ABSTRACT:
In a machine for dispensing stackable roofing washers individually and for driving fasteners through such washers, a shuttle is actuatable to displace a lowermost washer of one from a stack, either a small, circular or large, square washer. A gate is biased toward a lowermost position wherein it provides sufficient clearance for the lowermost washer but not any overlying washer to pass beneath it. A pawl mounted pivotally to the gate is biased to a lowermost position wherein the pawl engages a small washer displaced by the shuttle so as to restrain it against backward movement. A stop is adjustable so as to limit movement of a washer of whichever size is being displaced. A measuring bar is mounted via the stop. A screw gun, which provides a primary handle, and a secondary handle are mounted to an upright element so as to be independently adjustable.
