Each fastener has two protuberances located on one side and two corresponding and aligned indentations located on the other side, wherein the two protuberances of each fastener respectively engaged with the two indentations of an adjacent fastener, thereby interlocking two adjacent fasteners together. In a broader embodiment, each fastener has at least one protuberance located on one side and at least one corresponding and aligned indentation located on the other side wherein the at least one protuberance of each fastener respectively engages with the at least one indentation of an adjacent fastener, thereby interlocking two adjacent fasteners together.

Abstract: A fastening device comprises a “U” shaped spacer wherein the recess of the “U” shape is captured by the upper cross bar of a staple when the staple is used to fasten a protective sheeting to an item to be stored or transported. The spacer has a flat bottom surface and a flat side surface. The flat bottom surface increases the surface area of the staple in contact with the item during transport thereby reducing the chances that the protective sheeting may become torn from the item. The flat side surface increases the surface area of the standard staple during removal of the plastic sheeting because the spacer rotates about the crossbar of the staple. This rotation of the spacer reduces frictional contact between the spacer and the protective sheeting so that when the plastic sheeting is pulled from the lumber, the plastic sheeting will pull the spacer and the staple therefrom.

Abstract: The present invention is a fastener assembly including a row of fasteners maintained in position by a carrier. The carrier includes a plurality of adjacent sleeves, each of which includes an upper breakable portion, a middle wall portion, and a lower breakable portion. When a fastener is driven into a work piece, the upper and middle portions of the fastener sleeve break away and the lower portion breaks into fragments, so that no residual sleeve parts remain with the fastener. This is accomplished by forming the carrier from a mixture of a stiff polyolefin material and a particulate filler to impart the necessary brittleness to the carrier sleeves. The plurality of carrier sleeves include two end sleeves. At least one end sleeve includes a lateral end extension in the lower breakable portion which helps to balance and stabilize the fastener assembly in the shear block and magazine holder of a fastener driving tool.

This is accomplished by forming the carrier from a mixture of a stiff polyolefin material and a particulate filler to impart the necessary brittleness to the carrier sleeves. Also, the lower portion of the sleeve includes fragmentable tabs joined at wall junctions which are structurally weaker than the tabs, to facilitate fragmentation between the tabs.

Abstract: Collated drywall screws are provided for securing drywall to framing members. A collated screw has screws connected to each other by a holding strip. Each screw is received in a frangible sleeve about its threaded shank such that a screw on being screwed into a workplace is separated from the strip by the head of the screw passing through the sleeve breaking the sleeve. The improvement arises in having the head of the screw spaced from the frangible strip by a distance greater than the thickness of the drywall such that a screw is screwed through the drywall in at least partially into the frame support prior to the head of the screw engaging the frangible strip. The increased engagement with the frame member prevents the screw from stripping in the drywall and drawing drywall powder which may clog the power driver after repeated use. The invention provides drywall screws and a method of driving them which reduces the forces a user must manually apply to a power driver.

Abstract: A collated fastener strip for use in a pneumatic fastener driving tool of the type having a magazine containing parallel spaced grooves for accommodating the heads of fasteners as they are fed within the magazine. The strip comprises a plurality of headless fasteners with at least one headed fastener positioned near the end of the strip such that the strip may be used in a magazine designed for using headed fasteners.

Abstract: The fastener strips are made from a band of wires which consists of a series of parallel spot-weldable metallic wires disposed side by side, contiguously and spot-welded to each other at longitudinally spaced points of the wires and arranged along lines transverse to the bands. The spot welds are produced by a laser beam swept across the band as the same is continuously moving. The band is thereafter cut and stamped to form fastener strips. The spot welds constitute frangible joints holding the fasteners together for manual handling of the strip but breaking when the fasteners are subjected to a separating force such as when used in a pneumatic nailer.

The molded pack includes a plurality of nails that are supported in a spaced apart relationship by a first upper web and second lower web molded integrally with adjacent nails. In a second embodiment of the invention, the nails are connected by a vertically disposed web extending between overlapping heads of adjacent nails in the pack. Each web has a weakened section located so that a nail positioned in the gun chamber separates cleanly from the pack when struck by the gun hammer thereby preventing the gun from becoming jammed.

Abstract: A nail retaining strip for feeding nails into a fastening element driving tool where the nails are driven individually out of the tool by a drive piston includes guide bushings for the nails. Adjacent guide bushings are separably interconnected by connecting webs. The guide bushing extends in the axial direction of the nail shank and has axially and circumferentially extending circular guide surfaces for supporting the nails within the muzzle bore of the driving tool. The connecting webs extend radially outwardly from the guide surfaces so that the guide surfaces on adjacent guide bushings are in spaced relation. The connecting webs retain the nails in the axial direction of the muzzle bore by engagement in a receiving recess in the bore located opposite a passage through which the nails are inserted into the bore. Such axial retention permits complete utilization of the nail strip down to and including the last nail.

The nail end remote from the head has a penetration portion with at least one point. The profiling of the nail shank (4), the curved portion (7) and the head (5) is such that these portions have substantially the same cross-sectional shape, the sheet metal in the nail being of substantially uniform thickness.

Abstract: A continuous nail for an automatic nailing machine is disclosed in which each nail (2) of a continuous nail (1) is integrally moulded with a resin in which reinforcing material is mixed to improve its strength. The resin is selected from thermoplastic materials such as polyamide resin to result in good compatibility with the materials to be nailed. Moreover, the sectional configuration and surface characteristics of the shaft (4) of each nail (2) is shaped and finished to make the nail (2) difficult to pull out. Also, the configuration of the head (3) of the nail (2) is shaped and/or colored to give it a good nailing finish on the plaster board pasted with paper.

Abstract: Obliquely cohered fasteners may be formed by adhering wires with an adhesive coating to form a strip. The strip is then shaped so that the wires are formed into fasteners of the desired shape. The adhesive coating is then plasticized and while plasticized, each fastener is offset from the next to obtain the obliquely cohered fasteners. Then, the adhesive coating is rehardened. Instead of applying a single adhesive coating, the wires may be adhered with a first thermoplastic coating and a second coating of a non-self-adhesive resin. The second coating may be applied only to that portion of the first coating covering the fasteners. Alternatively, as the fasteners are offset, the second coating may be cracked between fasteners to weaken the second coating, allowing the fasteners to be more easily separated when desired. The off-setting may be performed by a device which applies a force to one of the ends of the fasteners while the other of the ends of the fasteners are displaced.
