Abstract: A clip crimping tool includes a body provided with a hollow air storage area and a drive section provided with piston cylinder and a piston, and having a main valve with a diameter that is larger than the piston cylinder and is arranged with the drive section is in line or at an angle with a contact section in which clips are crimped. The air storage area and the arrangement of the main valve and piston cylinder allow the free flow of compressed air into the piston cylinder to provide a fast and efficient drive action.

Abstract: A T-Nut having a generally tubular barrel with an interior female thread and a flange with prongs bent to embed in a work piece, and in which the flange has planar sides to ride in a feed guide, and has end edges on the flange, at the leading and trailing edges of the flange, which end edges can contact respective end edges on leading and trailing T-Nuts within the feed, a generally median U-shaped depression formed in each of the leading and trailing edges and, generally arcuate recesses formed in each of the edge flange, on either side of the U-shaped depression.

Abstract: A Tee-nut fastener device having a tubular threaded sleeve and a flange around one end of the sleeve and a through bore extending from one end of the sleeve to the other, and a closure sealing the flange end of the sleeve while leaving the opposite end of the sleeve open.

Abstract: A Tee-nut having a flange head, a plurality of prongs extending from the flange head, and a hollow sleeve extending from the flange head. The hollow sleeve has an internally threaded reduced diameter waist portion connecting to the flange head, and an enlarged globular bulbous portion extending from the internally threaded waist portion. The end of the enlarged bulbous portion is radiussed inwardly to facilitate insertion into a hole in a workpiece. Also disclosed is a workpiece fitted with such a Tee-nut.

Abstract: A nail with offset reinforced head, adapted to be formed into a strip of similar collated nails, comprises a nail shank, an integral nail head disposed in an offset relationship with the nail shank, at least one reinforcing ridge member provided integrally on a lower surface of the head and extending from the shank to an edge portion of the head. The ridge member and a lower surface of the head define a recess for receiving an overlapping head portion of a collated nail.

Abstract: A nail strip for use in association with a power-operated nailing device having strip feeding pawls and having a plurality of nails arranged in parallel spaced-apart relation, thermoplastic collars formed around the nails, webs extending between adjacent collars formed integrally, of a like thermoplastic material, engagement surfaces defined by asymmetric shoulders formed on the collars for engagement by the strip feeding pawls, and, the webs lying in a common plane spaced to one side of the plane containing the shoulders.

Abstract: A nailing strip for use in a power-operating nailing hammer, and having a plurality of nails arranged in a strip, a junction wire fastened to the shank of each nail in the strip, and a sheath covering the wire.

Abstract: A fastener member having a base flange, a central perpendicular sleeve with internal threads for reception of a threaded fastening, fastening teeth struckout of such base flange for reception in a wooden work piece, the base flange having a forward feed edge and a rearward feed edge, and side feed edges, and abutment means in the base flange adjacent the feed edges and spaced apart from the fastening teeth, adapted to inter-engage with one another to prevent such feed edges from overriding one another in a feed track.

Abstract: A nail feed mechanism for use in power operated nailing guns having a strip of nails joined by two lengths of wire at spaced intervals, for feeding the nails from a magazine to a barrel, and having a nail feed channel, a nail feed pawl adjacent to such channel with abutments interengageable with the nails to advance them into the barrel, contoured surfaces on such abutments around which the wires are bent over when the nail is driven in and spacers on the pawl maintaining the nail out of contact with the bent over portions of wire.

Abstract: A magazine for use with a fastener driving tool employing a strip of fasteners formed into a coil, and having a fixed portion to be fastened to such a tool, wall means forming a portion of said fixed portion for engaging such a coil of fasteners, a mounting member on the fixed portion along an axis centrally of the coil of fasteners, a movable attachment member incorporated in the mounting member, and movable between locking and releasing positions, a movable magazine portion defining wall means adapted to engage the coil of fasteners, exit means on at least one of the fixed and movable magazine portions, for exit of the fasteners, a slidable guide member formed on the movable portion, interengageable with the mounting member, and locking abutment means located inwardly of the guide member, for interengaging with the locking means on said fixed magazine portion.
