Description

BACKGROUND OF THE INVENTION

The present invention relates to a novel woodworking tool for precisely measuring difficult inside and outside dimensions critical for fine woodworking and cabinetry. More particularly, it relates to a woodworking gauge that can measure square ends, measure square/mitered end combinations, measure mitered ends, scribe arcs, and check diagonal squareness of cabinets and other structures.

Fine woodworking projects require precise measurements before preforming cuts and/or assembly. Often, numerous tools are required to ensure proper measurements. Accurately measuring inside dimensions of windows or cabinets, for example, is difficult with a measuring tape. Once this gauge is locked to the exact dimensions, the tool can create a pattern for a new piece of trim with mitered or square corners by setting a saw stop, fence, or by scribing a knife line on top of the stock from which you are creating the new piece. Additionally, trammel points for making circles and arcs can be removably affixed at either end. By rotating the trammel points to extend from both ends of the gauge, the gauge can be used to measure diagonals, which is useful for squaring up cabinets and other structures.

Prior art woodworking devices have been to designed to do each of the aforementioned actions; however, no prior art discloses a gauge that does all of the aforementioned actions. Therefore, there is a need for a woodworking gauge that is simple to operate and can measure square ends, measure square/mitered end combinations, measure mitered ends, scribe arcs, and square up cabinets and other objects. This need will be achieved by the novel invention herein disclosed.

SUMMARY OF THE INVENTION

DETAILED DESCRIPTION

There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof that follows may be better understood and in order that the present contribution to the art may be better appreciated. There are, of course, additional features of the invention that will be described hereinafter and which will form the subject matter of the claims appended hereto.

In this respect, before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and to the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced and carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein are for the purpose of descriptions and should not be regarded as limiting.

Looking at FIGS. 1 and 2 the main elements of the multi purpose adjustable measuring gauge 2 can be best seen. The first linear member 4 is extendably engagable with second linear member 6 by virtue of the insertion of the T-shaped track 8 into the matingly conformed T-shaped groove 10. Linear locking thumbscrew 12 tightens to frictionally bind the first linear member 4 and the second linear member 6 in any of the extended configurations of these elements.

Referring now to FIGS. 3-6 the first linear member can be best illustrated and described. First linear member 4 is of generally linear quadrilateral configuration, comprised of a uniform thickness A, a first planar face 14 and a second planar face 16, a proximal end 18, a distal end 20, and a T-shaped track 8. The proximal end 18 is squared and the distal end 20 is at a 45 degree angle (although alternate angles may be used this angle is the most common for woodworking applications.) Track 8 lies along the centerline of the first planar face 14 and extends the entire linear length of the first planar face 14 to slidably engage the matingly conformed groove 10 of the second linear member 6 (although different track and groove configurations may be utilized, this style has economic advantages.) Additionally, two nuts 22 are disposed and affixed through first opening 24 and second opening 26 and are threading engageable for coupling with a thumbscrew 28 (FIGS 11 and 12). The heads of nuts 22 are recessed in the second face 16 so as to remain at least flush with the second face 16.

The second linear member 6 is of generally linear quadrilateral configuration of uniform thickness B substantially similar to the thickness A of first linear member 4. The second linear member 6 comprises a third planar face 30, a fourth planar face 32, a squared proximal end 34, an angled distal end 36 of 45 degrees, and a groove 10 extending along its entire linear length matingly conformed to the track 8 for slidable engagement with the first linear member 4. The second member 6 further comprises a proximal end plate 38 having a substantially similar thickness as that thickness A and B of both the first and second linear members 4, 6 matingly affixed to the forth planar face 32 via three pop rivets 40 to the second linear member's proximal end 34 (although in a different type of fabrication the proximal end plate 38 and the second linear member 6 may be integrally formed.) Additionally, the proximal end plate 38 has a nut 22 disposed through an third opening 42 to be coupled with a thumbscrew 28 in a similar fashion as that described above. The nut 22 is recessed in the proximal end plate 38 so as to remain at least flush with the exposed face 44. A distal end plate 46 having a substantially similar thickness as that of thickness A and B of the first and second linear members 4 and 6 and that of proximal end plate 38, is matingly affixed via three rivets 40 to the third planar face 30 of second linear member's distal end 36. The distal end plate 46 and the proximal end plate 38 reside on opposite planar faces of the second linear member 6. The proximal end plate 38 matingly conforms to the distal end 20 of the first linear member 4, and the distal end plate 46 matingly conforms to the squared proximal end 18 of the first linear member 4. A thumb screw 28 is used to lock the first linear member 4 to the second linear member 6.

Looking at FIG. 5 the proximal end view of the second linear member 6 showing the groove 10 can be seen. This view is also identical for the distal end of the second linear member 6 when the second linear member is rotated end for end about the X-Y horizontal axial axis of the second linear member 6.

Looking at FIG. 6 the proximal and distal end view of the first linear member 4 showing the track 8 can be seen.

Referring now to FIGS. 7 to 12, two scribe attachment devices can be seen. The first scribe attachment device 48 has a first planar face 50 a second planar face 52, and four substantially similar edge faces differing only wherein a first edge face 54 has an orifice 56 therein to accept and frictionally or mechanically constrain a scribe 58. The second scribe attachment device 60 has a first planar face 62 a second planar face 64, and four substantially similar edge faces with the four faces differing only wherein a first edge face 66 has an orifice 68 therein to accept and frictionally or mechanically constrain a scribe 58.

The first and second scribe attachment devices each have a central orifice (not illustrated) formed therethrough for the entry of thumbscrew 28 but differ in the configuration of their first planar faces 50 and 62. The first scribe attachment device 48 has a square plate 64 formed centrally thereon dimensioned so as to be received by groove 10 on the second linear member 6. There is a central orifice formed therethrough (not illustrated.) In this manner the square plate 64 of the first scribe attachment device 48 may be placed into groove 10 and the thumbscrew 28 tightened into the nut 22 recessed into third opening 42 of proximal end plate 38 so as to secure the first scribe attachment device 48 in a non rotatable fashion so as to be squared with the proximal end 34 of the second linear member 6. A retaining clip 70 is affixed to thumbscrew 22 to hold it on the first scribe attachment device 48. The first scribe attachment device 48 may be locked into any of four orientations each 90 degrees apart so that the scribe 58 may extent parallel or perpendicular to the longitudinal axis of the gauge 2.

The second scribe attachment device 60 has four substantially similar squared platforms 72 formed at its corners so as to form a depressed region 74 there between in the shape of a cross so as to allow the track 8 to reside in the depressed region 74 in any of the possible 90 degree rotations of the second scribe attachment 60. In this manner the second scribe attachment device 60 may be placed onto track 8 in any of the possible 90 degree rotations and the thumbscrew 28 tightened into the nut 22 recessed into first opening 24 of the first linear member 4 so as to secure the second scribe attachment device 60 in a non rotatable fashion so as to be squared with the proximal end 18 of the first linear member 4. A retaining clip 70 is affixed to thumbscrew 28 in a recess 76 to hold it on the second scribe attachment device 60 similar to that discussed above. The second scribe attachment device 60 may be locked into any of four orientations each 90 degrees apart so that the scribe 58 may extent parallel or perpendicular to the longitudinal axis of the gauge 2.

FIG. 11 shows a side view of the assembled second scribe attachment device 60 and FIG. 12 shows a side view of the assembled first scribe attachment device 48.

FIG. 13 shows a side view of the second scribe attachment device 60 partially engaged with the first linear member 4 and FIG. 14 shows a side view of the first scribe attachment device 48 fully engaged with the second linear member 6.

The second scribe attachment device 60 is locked onto the proximal end of the first face 14 of the first linear member 4 such that the scribe 58 extends perpendicular to the longitudinal axis of the gauge 2.

The multi function gauge 2 could be formed from wood, light weight metals, steels, alloys, plastics, or any combination thereof. Although described as use for woodworking, the present invention is equally applicable to use in all other fields where precise measurement is critical such as metalworking, drafting, pattern making and the like.

The above description will enable any person skilled in the art to make and use this invention. It also sets forth the best modes for carrying out this invention. There are numerous variations and modifications thereof that will also remain readily apparent to others skilled in the art, now that the general principles of the present invention have been disclosed. As such, those skilled in the art will appreciate that the conception, upon which this disclosure is based, may readily be utilized as a basis for the designing of other structures, methods and systems for carrying out the several purposes of the present invention. It is important, therefore, that the claims be regarded as including such equivalent constructions insofar as they do not depart from the spirit and scope of the present invention.
