ABSTRACT:
A hand held pneumatic screw aligner feeder device which may be used in any orientation incorporates a container for loose screws made up of two cup shaped walls forming a hopper, a groove between the walls used to align the screws, a separator to keep unaligned screws out of the groove, a chute to carry the screws to a pawl which allows only a single screw to be delivered to a transfer chamber and an inlet for compressed air along one of the hopper walls. The device may be coupled to a pneumatic screw tightener such that a screw in the transfer chamber is forced down a hose to the nose of the tightener so that the screw may be forced into an external surface. An actuating valve system within the aligner feeder tightener device, coupled to the tightener nose allows compressed air to flow to the aligner feeder when the tightener is not in use, and to the tightener only when the tightener is activated.
