Apparatus for handling and feeding of groups of fasteners such as screws to an applicator or applicators for applying workpieces such as hinges to a base at a series of worksites. A dispenser at a charging site receives from a fastener feeder a charge of the groups of fasteners needed at all of the worksites of the series and then moves consecutively to each of the worksites to dispense a group of fasteners to an applicator at each worksite. A plurality of passageways extend from a fastener receiving side at the top to a fastener discharge side at the bottom of the dispenser, one passageway for each fastener to be dispensed. The discharge ends of the passageways register with receiving apertures at the applicator at each site. A series of gates at positions along the passageways selective hold and release groups of fasteners at their respective positions.
A dispenser for consecutively feeding groups of fasteners to an applicator for application of the groups of fasteners at separate locations, the dispenser being capable of receiving fasteners from a fastener charger at a fastener receiving side thereof and of feeding the fasteners in groups to a discharge side of the dispenser and having a plurality of passages for fasteners extending between the receiving side and the discharge side, a plurality of gates spaced from one another at positions between the receiving side and the discharge side for selectively closing off flow of fasteners along the passages at each gate position and a gate operator for opening and closing each gate, whereby a fastener may be introduced in each passage at the receiving side and, by selective operation of the gates, held at each gate position and selectively released to flow a further distance toward and/or out of the passage at the discharge side of the dispenser.
Apparatus for applying workpieces to a base at a series of worksites on the base with groups of fasteners which comprises
Apparatus for applying, with screws, a series of hinges with leaves have screw mounting holes to a juxtaposed door edge a and a face of a door jamb, with the hinge leaves opened and with one hinge leaf laid against the door edge and the other leaf against the jamb face, each hinge being applied to a respective application site along the door edge and jamb face which comprises
18 Apparatus as in claim 16 and wherein the appliance includes means for receiving, holding and applying an open hinge and applying the open hinge against the door edge and jamb face in preparation for driving the screws.
Apparatus as in claim 18 and wherein the shuffle additionally bears screwdrivers positioned to drive the screws held by the appliance at the door edge and jamb face through the screw holes and into the door edge and jamb face.
