Abstract In a washer-dispensing machine, a chute open at a lower end receives a stack of roofing washers of a type having a central aperture to receive a fastener shank and possibly having downwardly extending barbs. A shuttle engages a single washer from the stack, displaces the single washer to a separated position as the shuttle is moved from a displaced position to a normal position, and releases the single washer in the separated position as the shuttle next moves from the normal position to the displaced position. A known mechanism is employed for moving the shuttle between the displaced position and the normal position. A novel mechanism is mounted operatively to the chute for supporting the stack so as to prevent any of the washers in the stack from dropping through the lower end of the chute and for releasing the stack so as to permit a lowermost washer in the stack to drop through the lower end of the chute. A preferred embodiment includes two stack-supporting fingers and two finger- moving plates, each finger-moving plate coacting with one of the stack-supporting fingers and coacting with a shuttle-moving mechanism so as to support and release the stack appropriately as the machine is operated. An alternative embodiment includes two pivotably mounted, stack-supporting fingers coacting with a shuttle-moving mechanism so as to function similarly.
