Abstract
A pneumatic fastener inserter and hopper for the same is disclosed for use in inserting fasteners into material being secured. The hopper comprises a rotatable drum which tumbles the fasteners therein into position so that the shanks thereof protrude outwardly between spaced-apart bars. The fasteners are discharged from a discharge opening formed in the hopper and are delivered to a magazine which is in communication with an entrapment apparatus which feeds the fasteners to a feed tube under pressure. The air pressure in the feed tube delivers the individual fasteners to the inserter with the fastener being positioned between pivotally movable head fingers which open to receive the fastener to position the same for subsequent insertion and which pivot to enable the fastener to be driven outwardly therefrom by a piston rod so that the fastener is driven into and through the material being secured.
