Abstract: A repeating nail-feeding structure for pneumatic nailing machine, installed in a pneumatic nailing machine, includes an air stream guiding tube, automatic return cylinder, and shifting element. The tube enables working air stream from the machine to enter the cylinder, thereby a piston stein of the cylinder is driven to a retracted position. The piston stein is returned to an extended position by the pressing of a return spring within the cylinder. The shifting element is fixed to the piston stein and provided with a shifting lever. The shifting lever is moved along with the piston stein to advance the strip nail of the machine. Thereby, when the nail is ejected, the strip nail is advanced simultaneously by the discharged working air stream. The requirement of extensive use is fulfilled due to no limitation to length of the strip nail and successive nail-feeding capability.

Abstract: Method and apparatus for dispensing of attachments comprising a pair of side members linked by a connector. A roll of fastener stock is fed to a reciprocatively driven slide head assembly at which the roll is advanced over an elastomeric feed belt to a pair of needles secured to a shuttle. Once inserted in the needles, an individual attachment is severed from the stock, and displaced over a preset distance by the shuttle into the path of a pair of ejector rods. The ejector rods force the side members of the attachment out of the needles for insertion in a fabric or other workpiece at the bottom of the head stroke. On return stroke of the head, the needles are withdrawn, ejector rods retreat, and the shuttle returns to its severing position in a manner to avoid mechanical interference. This design uses an electric motor driven fastener dispensing head, actuator slide and associated linkages for actuating the various mechanisms either on an on-demand or continuous basis.

The retainer can hold the stack in one of two orientations. In order to avoid jamming, the hook is held on the slide as it retracts or is realigned with the stack, if the hook has not been removed from the apparatus.

Abstract: A fore chamber assembly of a nailing gun serially feeds nails by gravity through a channel into a firing chamber. A nail head fence prevents the heads of trailing nails from underriding the heads of preceding nails and getting more than one nail in the firing chamber. The fence is vertically adjustable to work on different thickness nail heads. A safety link prevents firing of the gun unless the gun abuts the structure to be nailed and in that attitude applies a friction lock to nails in the fore chamber to prevent kickback of these nails upon gun firing. This lock is through a sliding cam and lever that engages a resilient button that in turn engages some of the nails. A feed magazine has spaced rails defining a slot that accepts loose nails in any orientation so long as their heads are on the rails with the nail shanks in the slot. The magazine rails are secured together by a cover that overlies the slot and nail heads and depending flanges that attach to the rails.
