Multi-application crimping or pressing tool

Abstract

A manual or powered crimping tool, and corresponding jaw set, are described that include a combination of provisions for crimping tangential type crimping elements and one or more circumferential type crimping elements. Various versions of the tool and jaw set are provided including tools and jaw sets that include provisions for using a selectively replaceable insert that significantly increases the range of applications of the tool or jaw set. Tool versions are also provided having insert receiving surfaces, such as when used with inserts, that also serve as crimping surfaces.

Description

BACKGROUND

Crimping or pressing tools are well known in the art and are used for many purposes. One of the best known uses is as a device for mechanically securing a fastener to an electrical wire or cable. Typically, one end of the fastener is in the form of a cylindrical, hollow sleeve, and the other end is an eyelet, pin or socket or similar fastener element. The sleeve is adapted for receiving an end of the wire or cable and is clamped thereon by deforming the sleeve through use of a crimping tool.

Another use for crimping tools involves clamping metal rings onto tubing or other fittings. An example of tools for this application is a tool for crimping metal fittings on cross-linked polyethylene (PEX) tubing. These tools are adapted for making PEX tubing connections such as used in porrtable water and radiant heating applications. Such tools have also been used in association with the commercially available ProPress™ copper systems with transitions to PEX systems.

Crimping tools may generally be characterized as being either of two types: circumferential or tangential.

A circumferential crimp tool typically has a set of jaws configured to provide a pair of crimping surfaces or crimp nest which is at least generally symmetric, for example circular, square, hexagonal, etc. ASTM F 1807, herein incorporated by reference, provides standards for systems of metal insert fittings utilizing a circumferential type crimp ring element for PEX tubing. Examples of circumferential crimping tools are described in U.S. Pat. Nos. 5,722,284 to Linsmeyer and 6,164,106 to Nghiem.

Tangential-type crimping tools are characterized as having a pair of projections or pincers that generally face one another. When using such tools, the pincers are positioned about an outwardly projecting portion or shoulders of a crimp element. ASTM F 2098, herein incorporated by reference, provides standards for systems of tangential type clamps for securing PEX tubing to metal insert fittings. An example of a tangential-type crimping tool is shown in U.S. Pat. No. 4,724,729 to Oetiker.

When using crimping tools, it is often necessary to select the tool that is of an appropriate (i) type, i.e. circumferential or tangential, and (ii) size for the particular application. The selection of either a circumferential or tangential configuration is determined by the particular application and in some instances, by the preference of the user. The selection of an appropriate size tool is governed by the particular application which in turn dictates the size of the crimping elements. Since applications can dictate a wide range of different sizes of crimping elements, and since it is difficult if not impossible to use a single crimp tool for all crimping elements, manufacturers typically provide different sized tools.

Using multiple crimping tools in the field and transporting the tools to and from the work site can be cumbersome and is generally undesirable. In order to at least reduce the number of crimping tools that may be required, manufacturers have provided crimping tools that can accommodate a range of different sized crimping elements. However, as far as is known, such tools have only accommodated a limited range of sizes of crimping elements of a particular type, i.e. circumferential or tangential. Thus, if applications exist for both types of crimping elements, i.e. circumferential and tangential, it is necessary to provide and use two separate tools or sets of tools. Accordingly, it would be desirable to provide a single tool that could be used with crimping elements of not only a variety of sizes, but also with different types such as circumferential or tangential crimping elements. Furthermore, it would also be desirable to provide a tool that could be used with a wide range, or multiple ranges, of sizes of crimping elements. Providing such a tool would reduce the overall quantity of crimping tools that an operator might otherwise require, which would be particularly desirable when performing crimping applications in the field.

Certain powered tools such as pressing tools, use a powered hand unit and multiple, selectively engageable jaws or jaw sets. Jaw sets are known that include circumferential crimping configurations. Other jaw sets are also known for tangential crimping applications. A problem with these tool systems, is that the manufacturing process to produce the jaw can be costly. Also, since each different size fitting generally requires its own jaw or jaw set, the cost of tools to cover a range of crimping sizes and applications increases as well as the inconvenience of having to bring all tools and jaws to the job site. Accordingly, it would be desirable to provide a powered tool and jaw set combination that could be used for both circumferential and tangential type applications.

Crimping or pressing tools that employ various jaw inserts to accommodate a range of crimping application sizes are known. For example, U.S. Pat. No. 6,772,618 to Frenken shows a pressing tool having removable jaw inserts. The insert allows the operator to use a single jaw set as a carrier for a single insert that can be selected from a set of such inserts. The inserts may vary with respect to size, profile or application. Additionally the inserts are significantly lighter, smaller and less expensive to produce than corresponding jaws. Examples of various known tool designs using inserts include U.S. Pat. Nos. 3,706,219 to Hoffman et al; 4,576,067 to Buck; 5,113,727 to Foster; and 7,188,508 to Hamm et al. Although generally satisfactory, this configuration still does not provide a single assembly that can be used for both circumferential and tangential type applications. That is, in order to use such a jaw set and insert assembly, for crimping tangential elements and then for circumferential elements for example, an operator must provide and transport one or more tools for the tangential crimping application and one or more tools for the circumferential crimping application. After crimping the tangential elements, the insert and possibly the jaw set, must be replaced with those adapted for crimping circumferential elements. Accordingly, a need remains for a single tool and jaw insert system that can accommodate both types of applications.

DETAILED DESCRIPTION

The present invention relates to a multiple application crimping or pressing tool that can be provided in either a manual or powered tool configuration. A preferred embodiment of the present invention tool is a dual application tool as described herein.

The multiple application tool can be used for crimping or pressing systems that are of the circumferential type, and those that are of the tangential type. The tool features a unique head configuration that accommodates both circumferential crimping elements and tangential crimping elements.

The multiple application tool, in yet another embodiment, can be utilized with one or more jaw inserts that enable a wide range of crimping applications, i.e. circumferential and tangential, and sizes. In particular, the multiple application tool can also accommodate multiple types of circumferential systems and in still further embodiments, in combination with tangential systems.

In still additional embodiments, the multiple application tool can be utilized with and/or incorporate ring assemblies similar for example, to those commercially available under the designation ProPress® Press Rings.

The term “jaw set” as used herein refers to jaw assemblies typically comprising two jaw members that are pivotally coupled or otherwise move relative to one another. The term jaw set refers to such jaw assemblies used in manual tools having handles or rearwardly directed members extending from the jaw members. The term jaw set also refers to ring sets or ring assemblies that can be used in crimping applications. The term also refers to such jaw assemblies used in powered tools. The term “jaw set” also includes similar tools or portions thereof such as those employing screw operated assemblies that apply a compressive force. For instance, pressing ring assemblies using screw operated manual or powered assemblies are noted. The term also includes like tools such as flare bars. Various representative examples of these jaw sets are described herein. Accordingly, the present invention encompasses not only the various jaw sets, but also manual tools and powered tools utilizing or including such jaw sets.

FIG. 1 illustrates a preferred embodiment tool 100 according to the present invention. The tool 100 features a circumferential crimping surface and a pair of tangential pincer portions. The tool 100 comprises a first jaw 110 and a second jaw 120 coupled to one another by an alignment member 150 and a hinge connector 190 described in greater detail herein.

FIG. 2 is a detailed view of the jaw set of the preferred embodiment tool 100 depicted in FIG. 1. FIG. 2 illustrates in greater detail the first and second jaws 110 and 120, a pair of tangential pincer portions 136, 138, and a circumferential crimping surface 140 defined by the jaws 110 and 120.

FIG. 3 illustrates the preferred embodiment jaw set used in the tool 100 depicted in FIGS. 1 and 2. FIG. 3 illustrates the jaw set with the alignment member 150 removed thereby exposing apertures 116 and 126 defined in the first and second jaws 110 and 120, respectively.

Referring further to FIGS. 1-3, each jaw defines a forward portion and an oppositely extending rearward portion. Each jaw also defines inner and outer edges extending between the forward and rearward portions. For example, the jaw 110 defines a forward portion 111 and a rearward portion 113. And, the jaw 120 defines a forward portion 121 and a rearward portion 123. Concerning the noted edges, the jaw 110 defines an inner edge 143 and an oppositely disposed outer edge 133. And, the jaw 120 defines an inner edge 145 and an oppositely disposed outer edge 147. Specifically and referring to FIG. 2, the inner edge 143 includes several segments such as a front segment 143a extending between a tangential crimping configuration and a circumferential crimping configuration, each of which is described in greater detail herein. The inner edge 143 also includes a medial segment 143b extending between the circumferential crimping configuration and the region generally overlaid by the alignment member 150. The inner edge 143 also includes a rear segment 143c generally extending from the location of the member 150 to the distal rearward end of the jaw 110. In certain instances, each of the inner edges 143 and 145 can include provisions as depicted in FIG. 3. There, the inner edge 143 includes an arcuate surface 143d adapted to receive and engage a pin (not shown) as is frequently used in jaw sets. The inner edge 143 can also include a recessed surface 143e that serves to reduce the overall length of the medial surface 143b. The inner edge 145 includes a correspondingly similar set of segments, a front segment 145a, a medial segment 145b, and a rear segment 145c. The first jaw 110 defines a front portion or nose 112 and an oppositely extending rear portion or arm 114. Defined in the first jaw 110 is a forward aperture 116 and a rearward aperture 118. Both apertures 116 and 118 extend through the thickness of the first jaw member 110. Similarly, the second jaw 120 defines a nose 122 and an oppositely extending arm 124. Defined in the second jaw 120 is a forward aperture 126 and a rearward aperture 128. Both apertures 126 and 128 extend through the thickness of the second jaw 120. Together, the first jaw 110 and the second jaw 120 define the tangential pincers 136, 138. Specifically, the first jaw 110 defines a first recessed surface 132 and the second jaw 120 defines a second recessed surface 134. The first recessed surface 132 together with a front leading surface of the nose 112 define a first pincer portion 136. Similarly, the second recessed surface 134 together with a front leading surface of the nose 122 define a second pincer portion 138. The first and second pincer portions 136 and 138 are preferably directly opposite from one another, and so aligned with one another. The jaws 110 and 120 also collectively define the circumferential crimping surface 140. Specifically, the first jaw 110 defines a first arcuate circumferential crimping surface 142 accessible along an inner edge 143 of the jaw 110. And, the second jaw 120 defines a second arcuate circumferential crimping surface 144 accessible along an inner edge 145 of the second jaw 120. The first and second circumferential crimping surfaces 142 and 144 are preferably directly opposite from one another, and so aligned with one another. The alignment member 150 serves to promote alignment and stability between the jaws 110 and 120 during use of the tool 100. The alignment member 150 defines corresponding apertures through which a first pin 152 and a second pin 154 extend. The pin 152 extends through the aperture 116 or otherwise rotatably engages the jaw 110. And, the pin 154 extends through the aperture 126 or otherwise rotatably engages the jaw 120. It will be appreciated that the pins can be in the form of hinge members, bolts, or other cylindrically shaped components that engage the jaws and alignment member together. Engaged to the arm 114 of the first jaw 110 is a first handle 160. The first handle 160 defines a forward connector region 162 and an oppositely disposed grip 164. Preferably, defined along the interior region of the first handle 160 is a stop member 166. Similarly, the second jaw 120 is engaged to a second handle 170. The second handle 170 defines a forward connector region 172 and an oppositely extending grip 174. Preferably defined within the interior region of the second handle 170 is a stop member 176. The first and second handles 160 and 170 preferably extend rearward of the corresponding jaws to which they are engaged. The first jaw 110 is coupled to the first handle 160 by a first connector 180 extending through an aperture defined in the connector region 162 of the first handle 160 and the rearward aperture 118 defined in the arm 114 of the first jaw 110. Similarly, the second jaw 120 is coupled to the second handle 170 by a second connector 182 which extends through an aperture defined in the connector region 172 of the second handle 170 and the rearward aperture 128 defined in the arm 124 of the second jaw 120. The first and second connectors 180 and 182 serve to engage the jaws to the respective handles. The jaws 110 and 120 are also coupled to one another by a hinge connector 190. The hinge connector 190 extends through corresponding apertures defined in both of the connector regions 162 and 172 of the first and second handles 160 and 170, respectively. The hinge connector 190 serves to provide a point about which the forward connector regions 162 and 172 of the handles pivot during use of the tool 100. It will be appreciated that the first and second connectors 180 and 182, and the hinge connector 190 can be in the form of hinge members, bolts, or other cylindrically shaped components that engage their respective members together.

The jaws 110 and 120 are operatively coupled to one another such that the respective pincer portions are aligned with one another and provide a tangential crimping configuration. That is, the resulting pincer arrangement enables crimping of tangential type crimping elements. Similarly, the recessed arcuate surfaces or edges, that are accessible along the inner edges of the jaws, and aligned with one another provide a circumferential crimping configuration. The resulting aperture or opening 140 defined in the jaws 110 and 120 when the jaws are closed such that the inner edge segments 143a and 145a, and 143b and 145b are in contact or approaching such contact, enables crimping of circumferential type crimping elements.

Specifically, as explained in greater detail herein, the surfaces 142 and 144 that constitute the opening 140 are configured such that the surfaces serve as an insert receiving surface and/or as a crimping surface. Although these surfaces are generally referred to herein as crimping surfaces, it will be understood that these surfaces can also be configured or serve as insert receiving surfaces. As used herein, the term “crimping surface” refers to a surface that contacts a workpiece or crimp element for subsequent crimping or other compression type application. The term “insert receiving surface” refers to a surface that receives and contacts an insert such as an insert element also described in greater detail herein. The insert, when received in the insert receiving surface, then contacts the workpiece or crimp element. The insert provides a crimping surface.

FIGS. 4-6 illustrate another preferred embodiment tool 200 according to the present invention. The tool 200 features two circumferential crimping surfaces and a pair of tangential pincer portions. The tool 200 comprises a first jaw 210 and a second jaw 220 coupled to one another by an alignment member 250 and a hinge connector 290 described in greater detail. The tool 200 and its jaw set features the previously described aspects of the tool 100 and its jaw set.

Referring further to FIGS. 4-6, the first jaw 210 defines a nose 212 and an oppositely extending arm 214. Defined in the first jaw 210 is a forward aperture 216 and a rearward aperture 218. Both apertures 216 and 218 extend through the thickness of the first jaw member 210. Similarly, the second jaw 220 defines a nose 222 and an oppositely extending arm 224. Defined in the second jaw 220 is a forward aperture 226 and a rearward aperture 228. Both apertures 226 and 228 extend through the thickness of the second jaw 220. Together, the first jaw 210 and the second jaw 220 define the tangential pincer portions 236, 238. Specifically, the first jaw 210 defines a first recessed surface 232 and the second jaw 220 defines a second recessed surface 234. The first recessed surface 232 together with a front leading surface of the nose 212 define a first pincer portion 236. Likewise, the second recessed surface 234 together with a front leading surface of the nose 222 define a second pincer portion 238. The jaws 210 and 220 also collectively define a first circumferential crimping surface 240a. Specifically, the first jaw 210 defines a first circumferential crimping surface 242a. And, the second jaw 220 defines a second circumferential crimping surface 244a. The jaws 210 and 220 also collectively define a second circumferential crimping surface 240b. Specifically, the first jaw 210 defines a third circumferential crimping surface 242b. The second jaw 220 defines a fourth circumferential crimping surface 244b. The alignment member 250 serves to promote alignment and stability between the jaws 210 and 220 during use of the tool 200. The alignment member 250 defines corresponding apertures through which a first pin 252 and a second pin 254 extend. The pin 252 extends through the aperture 216 or otherwise rotatably engages the jaw 210. And, the pin 254 extends through the aperture 226 or otherwise rotatably engages the jaw 220. Engaged to the arm 214 of the first jaw 210 is a first handle 260. The first handle 260 defines a forward connector region 262 and an oppositely disposed grip 264. Preferably, defined along the interior region of the first handle 260 is a stop member 266. Similarly, the second jaw 220 is engaged to a second handle 270. The second handle 270 defines a forward connector region 272 and an oppositely extending grip 274. Preferably defined within the interior region of the second handle 270 is a stop member 276. The first and second jaws 210 and 220 are coupled to one another by a first connector 280 extending through an aperture defined in the connector region 262 of the first handle 260 and the rearward aperture 218 defined in the arm 214 of the first jaw 210. Similarly, the jaws 210 and 220 are also coupled to one another by a second connector 282 which extends through an aperture defined in the connector region 272 of the second handle 270 and the rearward aperture 228 defined in the arm 224 of the second jaw 220. The hinge connector 290 extends through corresponding apertures defined in both of the connector regions 262 and 272 of the first and second handles 260 and 270, respectively.

The operation of tools 100 and 200 can be described by reference to FIG. 1 and depiction of tool 100. A user, wishing to fasten or otherwise engage a crimp element (not shown) which for example, has been appropriately positioned such as along an interface of tubing to be joined, determines whether the crimp element is of the tangential or circumferential type. The user then opens the jaws 110 and 120, i.e. the jaw set, by separating the handles 160 and 170 from one another. The jaw set is then positioned about the crimp element of interest. If the crimp element is a tangential type, then the pincer portions 136 and 138 of the tangential crimping surface defined by the jaws 110 and 120 are placed across and in contact with the outwardly projecting shoulders of the crimp element. The user then urges the handles 160 and 170 of the tool 100, together, thereby also moving the pincer portions 136 and 138 toward one another. In the event the crimp element is of the circumferential type, the opened jaw set is positioned about the element such that the element is between the circumferential crimping surfaces 142 and 144. Upon closure of the jaw set by urging the handles together, the circumferential crimping surfaces contact and engage the crimp element and fasten that element in place.

Tools 100 and 200 are examples of preferred embodiments of manual tools in accordance with the present invention. The present invention also includes manual tools like tools 100 and 200, but instead of providing one or two circumferential crimping surfaces in combination with a pair of tangential pincers, provide three or more circumferential crimping surfaces in combination with a pair of tangential pincers.

In addition to manual crimping tools, the present invention also provides powered crimping tools, and particularly, jaw sets adapted for use with powered tools.

FIG. 7 illustrates a preferred embodiment jaw set 300, adapted for use with powered tools according to the present invention. The jaw set 300 comprises a first jaw 310 and a second jaw 320 coupled to one another by an alignment member 350 and associated members described in greater detail.

Referring to FIG. 7, the first jaw 310 defines a nose 312 and an oppositely extending arm 314. Defined in the first jaw 310 is an aperture (not shown) through which a pin 352 extends. Similarly, the second jaw 320 defines a nose 322 and an oppositely extending arm 324. Defined in the second jaw 320 is an aperture (not shown) through which a pin 354 extends. Together, the first jaw 310 and the second jaw 320 define a pair of tangential crimping pincers 336, 338. Specifically, the first jaw 310 defines a first recessed surface 332 and the second jaw 320 defines a second recessed surface 334. The first recessed surface 332 together with a front leading surface of the nose 312 define a first pincer portion 336. Similarly, the second recessed surface 334 together with a front leading surface of the nose 322 define a second pincer portion 338. The jaws 310 and 320 also collectively define a circumferential crimping surface 340. Specifically, the first jaw 310 defines a first circumferential crimping surface 342. And, the second jaw 320 defines a second circumferential crimping surface 344. The alignment member 350 serves to promote alignment and stability between the jaws 310 and 320 during use of the tool 300. The alignment member 350 defines corresponding apertures through which the first pin 352 and the second pin 354 extend. The alignment member 350 also defines an aperture 356 which serves to receive a retention member (not shown) when the jaw set 300 is engaged with a powered tool, as described in greater detail herein.

FIG. 8 illustrates another preferred embodiment jaw set 400 adapted for use with a powered tool according to the present invention. The jaw set 400 comprises a first jaw 410 and a second jaw 420 coupled to one another by an alignment member 450 and associated members described in greater detail. The first jaw 410 defines a nose 412 and an oppositely extending arm 414. Defined in the first jaw 410 is an aperture (not shown) through which a pin 452 extends. Similarly, the second jaw 420 defines a nose 422 and an oppositely extending arm 424. Defined in the second jaw 420 is an aperture (not shown) through which a pin 454 extends. Together, the first jaw 410 and the second jaw 420 define a pair of tangential pincer portions 436, 438. Specifically, the first jaw 410 defines a first recessed surface 432 and the second jaw 420 defines a second recessed surface 434. The first recessed surface 432 together with a front leading surface of the nose 412 define a first pincer portion 436. Similarly, the second recessed surface 434 together with a front leading surface of the nose 422 define a second pincer portion 438. The jaws 410 and 420 also collectively define a first circumferential crimping surface 440a. Specifically, the first jaw 410 defines a first circumferential crimping surface 442a. And, the second jaw 420 defines a second circumferential crimping surface 444a. And, the jaws 410 and 420 additionally collectively define a second circumferential crimping surface 440b. Specifically, the first jaw 410 defines a third circumferential crimping surface 442b. And, the second jaw defines a fourth circumferential crimping surface 444b. The alignment member 450 serves to promote alignment and stability between the jaws 410 and 420 during use of the tool 400. The alignment member 450 defines corresponding apertures through which the first pin 452 and the second pin 454 extend. The alignment member 450 also defines an aperture 456 that serves to receive a retention member (not shown) when the jaw set 400 is engaged with a powered tool, as described in greater detail herein.

Jaw sets 300 and 400 are examples of preferred embodiment jaw sets adapted for use with powered tools in accordance with the present invention. The invention also includes jaw sets adapted for use with powered tools that include combinations of a pair of pincers for tangential crimping applications and three or more circumferential crimping surfaces.

FIG. 9 is a perspective view of the jaw set 400 depicted in FIG. 8, engaged with a powered pressing tool 500. The tool 500 comprises a housing 510, a handle 520, a battery pack 530, a forward end 540, and an oppositely directed rear end 550. The battery pack 530 preferably is selectively engageable along the distal lowermost end of the handle 520. The tool 500 includes a trigger 525 that upon actuation, initiates activation of the tool 500. Projecting from the front face of the forward end 540 is a receiving assembly 545 that is adapted to selectively engage a jaw set such as jaw sets 300 or 400, depicted in FIGS. 7 and 8 respectively.

Disposed within the interior of the housing 510 is an electric motor and drive assembly for imparting a drive force to the jaw set, such jaw set 400, engaged and received at the forward end 540 of the tool 500. A receiving assembly 545 forwardly projecting from the end 540 of the tool 500, includes provisions for receiving and engaging the jaw set 400. A retention member 548 or other similar component or assembly serves to retain and couple the jaw set 400 to the tool 500. The retention member 548 is releasably engageable with a jaw set by extending into or through the aperture 456 defined in the alignment member 450 of the jaw set 400, for example. Typically, upon pulling the member 548 to a release position, the member 548 is retracted from the aperture 456 and the jaw set 400 can be withdrawn from the tool 500. Details of the components, operation and assembly of the tool 500 are disclosed in various patents, such as for example, U.S. Pat. Nos. 5,111,681 to Yasui et al.; 5,611,228 to Dummermuth; 6,000,680 to Kimura et al.; 6,202,290 to Kewitz et al.; 6,244,085 to Dummermuth; 6,276,186 to Frenken; 6,401,515 to Frenken; 6,510,719 to Goop; 6,510,723 to Amherd; 6,662,621 to Amherd; and 6,718,870 to Frenken.

FIG. 10 illustrates a preferred embodiment gauge 600 in accordance with the present invention. The gauge 600 provides dimensional indicators for estimating or determining a range of sizes for circumferential crimping applications and tangential crimping applications. Preferably, and as depicted, the gauge 600 can be in the form of a “Go-No-Go” gauge as that term is understood by those skilled in the art. The gauge 600 serves as an inspection tool to check the extent of crimping or compression applied to a workpiece. The gauge 600 is a measuring tool that does not necessarily return a size in the literal sense, but instead returns a state. Specifically, the gauge 600 provides a series of circumferential, i.e. according to ASTM F1807, indicators such as 610, 620, 630, 640, 650, and 660. The gauge 600 also provides a series of tangential indicators such as 670, 680, and 690. As will be appreciated, each dimensional indicator is provided along the periphery of the gauge 600. The “Go-No-Go” aspect of the gauge 600 can be used to determine whether a circumferential crimped element has been sufficiently compressed about an underlying member. If, after crimping, the crimped element has an outer diameter small enough to fit within the Go indicator and has an outer diameter that is too large to fit within the corresponding No-Go indicator, then the element has been sufficiently compressed. If however, the crimped element fits in both of the Go and No-Go indicators, then the element has been excessively or overly crimped. If instead, the crimped element does not fit within the Go indicator, then the element has not been sufficiently crimped. The gauge is preferably formed from a relatively flat and thin sheet of a durable material such as metal or certain plastics.

The circumferential indicators of the gauge 600 are preferably slotted openings having a span or access width that corresponds to the desired range of diameters of the circumferential crimping element after crimping. That is, the preferred embodiment gauge defines a collection of openings, each of which corresponds to a minimum and maximum desired diameter of a circumferential crimping element after crimping. It is also preferred that the interior portion of each opening define an arcuate edge, and preferably, a semi-circular edge, having a diameter equal or substantially so, to the access width of the respective opening. Thus, for example, the circumferential indicator 610 defines an arcuate edge 612 that preferably extends through an arc of 1800 between a pair of side edges 614 and 616. The side edges are parallel to one another and spaced apart a distance corresponding to the desired diameter indicative of the indicator 610.

The tangential indicators of the gauge 600 are also preferably slotted openings. The span or width of each opening corresponds to the preferred maximum width of a tangential crimping element after crimping. This width, as will be appreciated by those skilled in the art, is the distance between the shoulders of the crimping element in its post-crimp state. It is frequently desirable, and often necessary, to utilize a tangential indicator to determine whether sufficient crimping has occurred. Depending upon the material of the crimp element and/or its physical characteristics, and also the characteristics of any underlying workpiece, after crimping, the gap between the shoulders of a crimped tangential type element may increase or “spring back” due to resiliency or elastic memory of the crimp element. Thus, it is beneficial to use a tangential crimp indicator to confirm that sufficient crimping has occurred. Inherently, it is likely that spring back occurs. The degree of spring back typically varies depending upon fitting size. This is the reason that the preferred embodiment gauge 600 provides indications for multiple sizes.

The present invention also provides a jaw configuration, a jaw set using such configuration, one or more jaw inserts, and a system of these features adapted for use with a manual or powered tool or tool assembly. Specifically, in this aspect, the invention provides a jaw configuration for a tool, manual or powered, which can be used for crimping or pressing applications, and which can be used in conjunction with one or more inserts.

More specifically, the present invention provides a wide variety of different style and different size inserts for use in conjunction with a jaw set as described herein. For example, in this aspect of the invention, a jaw set is provided that defines an insert receiving surface which in turn, receives an insert member that can be used to crimp a crimp element. The jaw set can be used to crimp a range of different sized crimp elements by appropriate selection of an insert of a size corresponding to the element to be crimped. In addition to the inserts varying from one another in size, the inserts may also vary from one another in one or more other characteristics such as, but not limited to crimp shape. Furthermore, in accordance with the present invention, jaw sets and/or inserts can be provided to accommodate multiple types or combinations of circumferential crimping systems.

FIGS. 11 to 15 illustrate a preferred embodiment jaw and an insert member in accordance with the present invention. Although the jaw depicted in these figures is of the type adapted for use in a powered tool, it will be appreciated that the following description is equally applicable to a manually powered tool. Specifically, FIGS. 11 and 12 illustrate a preferred embodiment jaw 700 comprising a jaw body 710, a nose 720, an oppositely extending arm 730, and a recessed insert receiving region 740. The jaw 700 defines first and second oppositely directed lateral faces 702 and 704, an outer edge 706, and an inner edge 708, both edges extending about opposite peripheral regions of the jaw 700. The jaw 700 preferably defines an aperture 750 for receiving an engagement member, such as for coupling an alignment member (not shown) thereto. The jaw 700 can also define a rearwardly disposed and preferably recessed region 760 that can carry logo(s) or other markings as desired.

The insert receiving region 740 is preferably defined by a concave, recessed, arcuate surface 742 that extends along the inner edge 708 of the jaw 700. Defined along one or both of lateral faces 702 and 704 of the jaw 700 are a plurality of retention members 744 and 746. The retention members 744 and 746 serve to align and preferably retain an insert member within and in contact with the surface 742 of the insert receiving region 740. Although the invention includes a wide array of designs and configurations for the retention members, a preferred configuration is that each member be in the form of an outwardly extending member. In certain instances, the retention members can be in the form of spring loaded or otherwise outwardly biased displaceable members that are received by or otherwise engaged with corresponding apertures or recesses in the insert. The insert can be retained to its corresponding jaw in nearly any fashion. For example, the present invention includes the use of magnetic retention strategies and the use of straps formed from elastomeric materials or metals that extend about the insert and outer surface of the jaw. A wide array of other retention strategies are contemplated and included in the present invention such as the use of selectively releasable pins or threaded connectors that temporarily affix an insert to the jaw. The surface 742, if used in conjunction with an insert as previously described, would then correspond to an insert receiving surface as that term is used herein. However, the surface 742 could also serve as a crimping surface.

FIGS. 13 and 14 illustrate a preferred embodiment insert member 800 in accordance with the present invention. The insert member 800 is preferably in the shape of a semicircle and includes a pair of lateral side walls 810 and 820 and an arcuate member 830 extending between the walls 810 and 820. The member 830 defines two oppositely directed surfaces, a convex mating surface 840 and an oppositely directed concave crimping or working surface 850. Each of the sidewalls 810 and 820 preferably include provisions for engaging one or more retention members provided in a corresponding jaw. For example, the insert 800 includes a plurality of receiving apertures or slots that engage the retention members 744 and 746 of the jaw 700 shown in FIG. 11 once the insert 800 is appropriately positioned in the insert receiving region 740 of the jaw 700. Specifically in this regard, the sidewall 810 defines apertures 812 and 814, and the sidewall 820 defines apertures 822 and 824.

The various inserts described herein feature outer surfaces for engagement and contact with jaws described herein. That is, the inserts feature an outer or backside surface configured to contact and preferably seat against a corresponding insert receiving surface defined in the jaw member. The inserts also feature an oppositely directed surface referred to herein as a crimping surface as such surface contacts a workpiece or crimp element for subsequent crimping. Referring to FIGS. 11-15 again, upon placement of insert member 800 in the jaw 700, the convex mating surface 840 of the insert 800 contacts and is engaged alongside the insert receiving region 740, and specifically the insert receiving surface defined therein of the jaw 700. Upon use of the jaw 700 and the insert 800, the crimping surface 850 of the insert contacts the workpiece or crimp element.

FIG. 15 is a perspective view of an assembly of the preferred embodiment jaw 700 and the preferred embodiment insert member 800 engaged therewith.

It will be appreciated that in using the jaw and insert assembly, two of the assemblies are used to provide a jaw set. And two or more inserts or insert members are utilized in a typical crimping application.

A jaw or jaw set and an insert member may be provided or implemented in combination with the dual crimping system described herein. That is, the present invention also provides a jaw set, adapted for use with a manual or powered tool or tool assembly, that includes jaw provisions for receiving insert members in combination with one or more tangential and/or circumferential crimping provisions. For example, the present invention includes a jaw set comprising provisions for receiving insert members in combination with a pair of tangential pincing portions. The invention also includes a jaw set comprising provisions for receiving insert members in combination with one or more circumferential crimping surfaces. The present invention also includes a jaw set having a combination of provisions for receiving insert members, a pair of tangential pincing portions, and circumferential crimping surfaces. In addition, the present invention includes a jaw set having multiple provisions for receiving insert members, such as a first set of insert members and a second set of insert members. The two or more different sets of insert members can vary by size, shape or configuration. It is also contemplated, to provide a jaw set that includes multiple provisions for receiving two or more sets of insert members in combination with a pair of tangential pincing portions, and/or one or more circumferential crimping surfaces. And, as previously noted, the jaw sets can be configured to accommodate multiple types or combinations of different types of circumferential crimping systems.

FIG. 16 illustrates a preferred embodiment jaw comprising provisions for receiving insert members in combination with a pair of tangential pincing portions. Specifically, FIG. 16 illustrates a jaw assembly 900 comprising a jaw 910 and an insert member 980. The jaw 910 defines a nose 912, an outwardly projecting pincer portion 936, and an arcuate insert receiving surface 950 adapted to receive the insert member 980. The jaw assembly 900 can be used in a jaw set to crimp tangential type crimping elements by use of the resulting pincer portions, one of which is shown as 936, and in addition, to also crimp a range of circumferential type crimping elements upon appropriate selection of the desired insert, such as insert 980. It will also be appreciated that the receiving surface 950, and a corresponding receiving surface in another complimentary jaw (not shown), can itself be utilized as a circumferential crimping provision.

FIGS. 17 and 18 illustrate jaw assemblies having provisions for receiving insert members in combination with one or more circumferential crimping surfaces. Specifically, FIG. 17 illustrates a jaw assembly 1000 comprising a jaw 1010 and an insert member 1080. The jaw 1010 defines a nose 1012 and an arcuate receiving surface 1050 sized and adapted to receive the insert member 1080. The jaw 1010 also defines a circumferential crimping surface 1040. FIG. 18 illustrates a jaw assembly 1100 comprising a jaw 1110 and an insert member 1180. The jaw 1110 defines a nose 1112 and an arcuate receiving surface 1150 sized and adapted to receive the insert member 1180. The jaw 1110 also defines a first circumferential crimping surface 1140a and a second circumferential crimping surface 1140b. The jaw assembly 1000 and the jaw assembly 1100 can each be used in a jaw set to crimp a relatively wide range of different sizes of circumferential type crimping elements. The jaw assembly 1000 enables circumferential crimping of a wide range of sizes, shapes, and configurations, since inserts of different sizes can be selected and positioned in the receiving surface 1050. The crimping surface 1040 can for example, be of a size that is popular or common. The jaw assembly 1100 is similar to jaw assembly 1000, however provides two sets of circumferential crimping provisions, i.e. 1140a and 1140b. This pair of crimping provisions may be of appropriate sizes to accommodate two common or popular sizes of crimping elements. Again, it will be appreciated that the receiving surface 1050 of the jaw 1010 and the receiving surface 1150 of the jaw 1110 (and corresponding surfaces in complimentary jaws forming useable jaw sets) can be used as circumferential crimping provisions.

FIG. 19 illustrates a jaw assembly having a combination of provisions for receiving insert members, a pair of tangential pincing portions, and circumferential crimping surfaces. Specifically, FIG. 19 illustrates a jaw assembly 1200 comprising a jaw 1210 and an insert member 1280. The jaw 1210 defines a nose 1212, a pincing portion 1236, a recessed arcuate surface 1250 sized and adapted to receive the insert member 1280, and a circumferential crimping surface 1240. As will be appreciated, this jaw assembly 1200 can be used in a jaw set for crimping (i) tangential crimping elements by use of tangential pincing portion 1236 and a complimentary portion (not shown) and (ii) a variety of different sizes of circumferential crimping elements, by use of the insert receiving surface 1250 and corresponding insert 1280, and circumferential crimping provisions provided by surface 1240 and complimentary portions (not shown).

FIG. 20 illustrates a jaw assembly having multiple provisions for receiving insert members, such as a first set of insert members and a second set of insert members. Specifically, FIG. 20 illustrates a jaw assembly 1300 comprising a jaw 1310 and a first insert member 1380a and a second insert member 1380b. The jaw 1310 defines a nose 1312 and a first receiving surface 1350a sized and adapted to receive the insert member 1380a. The jaw 1310 also defines a second recessed receiving surface 1350b that is sized and adapted to receive the insert member 1380b. The jaw assembly 1300 can be used in a corresponding jaw set to crimp a wide range of sizes of circumferential crimping elements by appropriate selection of sizes of inserts 1380a and 1380b. It is contemplated that the jaw assembly 1300 would be beneficial when crimping numerous circumferential style elements having a significantly wide range of different sizes. Also, as previously noted, in accordance with the invention, one or both of the receiving surfaces 1350a and 1350b can themselves constitute circumferential crimping work surfaces.

FIG. 21 illustrates a jaw assembly having multiple provisions for receiving two or more sets of insert members in combination with tangential pincing portions. Specifically, FIG. 21 illustrates a jaw assembly 1400 comprising a jaw 1410 and a first insert member 1480a and a second insert member 1480b. The jaw 1410 defines a nose 1412 and a pincing portion 1436. The jaw 1410 also defines a first recessed receiving surface 1450a and a second recessed receiving surface 1450b. The receiving surface 1450a is sized and adapted to receive the first insert member 1480a. The second receiving surface 1450b is sized and adapted to receive the second insert member 1480b. As previously described, the provision of a plurality of insert receiving surfaces enables the jaw assembly 1400 and corresponding jaw set to accommodate a wide range of sizes of circumferential style crimping elements. And, the provision of tangential crimping surfaces, such as the pincer portion 1436, enables the jaw assembly 1400 to also be used for tangential crimping applications.

FIG. 22 illustrates a jaw assembly 1500 comprising a jaw 1510, a first insert member 1580a, and a second insert member 1580b. The jaw 1510 defines a nose 1512 and first and second arcuate receiving surfaces 1550a and 1550b, respectively. The first receiving surface 1550a is sized and adapted to receive the first insert member 1580a. Similarly, the second insert surface 1550b is sized and adapted to receive the second insert member 1580b. The jaw 1510 also defines a circumferential crimping surface 1540. As will be understood from the previous descriptions of preferred embodiment jaws, the jaw assembly 1500, when used in a jaw set, accommodates an extremely wide range of different sizes of circumferential style crimping elements.

FIG. 23 illustrates a preferred embodiment jaw assembly 1600 comprising a jaw 1610 and first and second insert members 1680a and 1680b. The jaw 1610 defines a nose 1612 and a tangential pincing portion 1636. The jaw 1610 also defines a first arcuate receiving surface 1650a that is sized and adapted to receive the insert member 1680a. The jaw 1610 also defines a second arcuate receiving surface 1650b that is sized and adapted to receive the second insert member 1680b. The jaw 1610 also defines a circumferential crimping surface 1640. In addition to the jaw assembly 1600 accommodating a great range of different sizes of circumferential style crimping elements, the jaw 1600 can also be used for crimping tangential style crimp elements.

The present invention also provides a jaw set, or tool utilizing such jaw set, that includes a tangential crimping configuration located within the interior of the tool. That is, instead or in addition to, the provision of pincer portions disposed along the nose or front portion of the jaws, such pincer portions can be disposed within the interior of the jaw set, and accessible from one or more circumferential crimping provisions upon opening the jaws apart from one another. It is contemplated that the provision of interiorly disposed pincers that provide a tangential crimping configuration can also be provided in conjunction with a plurality of circumferential crimping provisions.

FIG. 24 illustrates another preferred embodiment jaw assembly 1700 comprising a first jaw 1710 and a corresponding second jaw 1720. This embodiment is an example of the present invention providing inserts that define a tangential crimping configuration, and particularly, one that is defined within the interior of the tool or jaw set. The jaw assembly 1700 features a tangential pincing configuration defined within the interior of the jaw assembly, by pincer members 1752 and 1762. The first jaw 1710 defines a nose 1712, an oppositely located end 1714 and an inner surface 1708. Similarly, the second jaw 1720 defines a nose 1722, an oppositely located end 1724 and an inner surface 1718. The jaw assembly 1700 is adapted for use in a powered pressing tool, and so, surfaces 1708 and 1718 are adapted for contact with rollers or other pressing components of the pressing tool. It will be appreciated that the present invention includes manual, unpowered versions of the jaw assembly 1700. The jaw assembly 1700 defines an interior receiving region for accepting crimping inserts 1780 and 1790. The first jaw 1710 defines a receiving surface 1750 which contacts an outer surface of the insert 1780. Similarly, the second jaw 1720 defines a receiving surface 1760 that contacts an outer surface of the insert 1790. An interiorly disposed tangential crimping provision can be accessed by removing the inserts 1780 and 1790. Upon such removal, pincer portions 1752 and 1762 can then be utilized for tangential crimping applications as described herein.

FIG. 25 is a detailed view of the insert 1790 depicted in FIG. 24. The insert 1790 defines an outer surface 1792 which is received by and engages the receiving surface 1760 of the second jaw 1720. The insert 1790 also defines one or more circumferential crimping surfaces such as 1794 and 1796. It will be appreciated that the present invention includes systems utilizing multiple inserts. For example, an insert such as insert 1790 can be used with additionary inserts that are received in surfaces 1794 and 1796. In this embodiment of the invention, a primary insert such as insert 1790 is positioned within a corresponding tool, and specifically in contact with an insert receiving surface defined within the tool. Next, one or more secondary inserts are then engaged with the primary insert, and specifically, in contact with the surfaces 1794 and/or 1796. Thus, the present invention includes inserts that provide multiple circumferential crimping provisions and/or define multiple insert receiving surfaces for accepting one or more secondary inserts. This strategy significantly increases the flexibility and application of the present invention tool, jaw sets, and inserts, to a wide array of uses.

As noted, the multiple application tool can also be in the form of ring sets or pressing ring assemblies, as known in the art. FIGS. 26-32 illustrate two representative examples of preferred embodiment pressing ring assemblies in accordance with the present invention. Specifically, FIGS. 26-28 illustrate a first preferred embodiment pressing ring assembly 1800. The assembly 1800 is depicted as a Propress® XLC/Propress® pressing assembly. The assembly 1800 includes a spring that biases the two portions or jaws of the ring assembly toward one another. The assembly is used by placing it over a fitting or element to be compressed or crimped, and then applying a compressive force at the nose end of the hinged jaws. Specifically, assembly 1800 comprises an upper jaw 1810, a lower jaw 1820 pivotally attached to the upper jaw 1810 such as by use of a pivot pin 1850. The upper jaw 1810 defines an upper crimping surface 1842 generally extending between a rear region 1813 at the vicinity of the pivot pin 1850, and a distal nose region 1836. The lower jaw 1820 defines a lower crimping surface 1844 generally extending between a rear region 1823 at the vicinity of the pivot pin 1850, and a distal nose region 1838. Together, the crimping surfaces 1842 and 1844 define a circumferential crimping surface 1840. Also preferably defined adjacent the nose regions 1836 and 1838 of the jaws 1810 and 1820, respectively, is a circumferential crimping configuration defined by a pair of recessed surfaces 1832 and 1834. The pressing assembly 1800 also comprises an optional compression segment 1870 disposed generally between the upper and lower jaws 1810 and 1820 and adjacent the rear regions of those jaws. The assembly 1800 additionally comprises a pair of opposing support members 1852 and 1854, fasteners 1860 and 1862, and retaining rings 1856 and 1858. A torsion spring 1864 is preferably utilized for biasing, as previously noted. Roll pins such as pins 1870, 1872, 1874, and 1876 can also be utilized in the ring pressing assembly 1800. In use, the assembly 1800 is positioned as desired, such as over a fitting or element to be compressed, and then a tool providing a compressive force, is then engaged in receiving regions 1802 and 1806 defined in the upper and lower jaws, respectively, and preferably in contact with surfaces 1804 and 1808 defined in the receiving regions 1802 and 1806. The surfaces 1804 and 1808 preferably define a concave or bowl-shaped depression. This configuration promotes receipt and engagement of members of a compressive force applying tool.

FIG. 29 is a side view of the pressing ring assembly similar to that depicted in FIGS. 26-28, utilizing a pair of removable inserts similar to those shown in FIGS. 24 and 25. Specifically, FIG. 29 illustrates the pressing ring assembly 1800 using a first insert 1880 and a second insert 1890. The first insert 1880 defines a first crimping surface 1884 and a second crimping surface 1886. The second insert 1890 defines a first crimping surface 1894 and a second crimping surface 1896. As will be understood, the inserts 1880 and 1890 can also serve as primary inserts and be used in conjunction with secondary inserts that are received and engaged in the corresponding pairs of surfaces 1884 and 1894, and surfaces 1886 and 1896.

FIGS. 30-32 illustrate another preferred embodiment pressing ring assembly 1900. The assembly 1900 includes a spring that biases the two portions or jaws of the ring assembly toward one another. The assembly is used by placing it over a fitting or element to be compressed or crimped, and then applying a compressive force at the nose end of the hinged jaws. Specifically, assembly 1900 comprises an upper jaw 1910, and a lower jaw 1920 pivotally attached to the upper jaw 1910 such as by use of a pivot pin 1950. The upper jaw 1910 defines an upper crimping surface 1942 generally extending between a rear region 1913 at the vicinity of the pivot pin 1950, and a distal nose region 1936. The lower jaw 1920 defines a lower crimping surface 1944 generally extending between a rear region 1923 at the vicinity of the pivot pin 1950, and a distal nose region 1938.
