Abstract: A fluid operated reciprocal slide picks off fasteners, one at a time, from a delivery slide and delivers the fasteners to a flexible conduit. The same fluid that moves the aforementioned slide drives the fastener into the flexible conduit and on to an automatic fastener insert mechanism. The fluid drive is selectively activated by the trigger at the automatic fastener insert mechanism.

Abstract: Fasteners, such as nails, tacks, screws, rivets or the like are continuously fed from a vibratory, bowl feed-type supply hopper into a vibrating delivery chute or slide from whence they are removed, one at a time, by an escapement mechanism and delivered into one end of a feed conduit that is connected at the other end to a fastener driving device. An air supply is connected to the conduit downstream from the outlet of the escapement mechanism thereby inducing a negative pressure which pulls the fasteners from the escapement mechanism and delivers them headfirst into the conduit and on to the receiving chamber of a fastener driving device. The fasteners are delivered into the receiving chamber headfirst in a rearward direction into engagement with the front end of the drive piston.
