Abstract
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.

5. The magazine of claim 4 wherein the supporting means further includes two finger-moving plate mounted operatively to the chute, each finger-moving plate being associated with one of the stack-supporting fingers and finger-moving plate being movable between an inoperative position and an operative position so as to flex the associated finger and to move the distal part of the associated finger to the stack-supporting position when said finger-moving plate is moved from the inoperative position to the operative position and so as to allow the distal part of the associated finger to move from the stack-supporting position to the stack-releasing position when said finger-moving plate is moved from the operative position to the inoperative position, each finger-moving plate being biased to the operative position.
6. The magazine of claim 1 wherein said means includes two such stack-supporting fingers mounted pivotably to the chute, each on a different side of an imaginary plane comprising an imaginary line through the central apertures of the respective washers in the stack.
7. In a washer-dispensing machine comprising a base, a magazine for a stack of roofing washers, and a shuttle, each washer being of a type having a central aperture to receive a fastener shank and possibly having downwardly extending barbs, the magazine including a chute supported by the base and adapted to contain the stack of roofing washers having downwardly extending barbs, the chute having a lower end, which is open, the shuttle being mounted to the base for horizontal movement between a normal position and a displaced position and adapted to engage a single washer from the stack when the shuttle is in the displaced position, to displace the single washer from the stack to a separated position by positive engagement with the single washer as the shuttle is moved from the displaced position to the normal position, and to release the single washer in the separated position as the shuttle next moves from the normal position to the displaced position, and means arranged to be normally deactuated and adapted to be operator-actuated for moving the shuttle from the normal position to the displaced position when actuated and for moving the shuttle from the displaced position to the normal position when deactuated, an improvement wherein the machine further comprises means 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 any for releasing the stack so as to permit a lowermost washer in the stack to drop through the lower end of the chute, the supporting and releasing means being operative for supporting the stack when the shuttle-moving means is actuated for moving the shuttle from the normal position to the displaced position and being operative for releasing the stack when the shuttle-moving means is actuated for moving the shuttle from the displaced position to the normal position.
8. The improvement of claim 7 wherein the supporting and releasing means includes a stack-supporting finger mounted operatively to the chute so that a distal part of the stack-supporting finger is movable between a stack-supporting position and a stack-releasing position, wherein the distal part extends beneath and engages the second to lowermost washer in the stack, through an aperture in the chute, when the distal part is moved into the stack-supporting position, and wherein the distal part is removed from engagement with any of the roofing washers in the stack, through the aperture in the chute, when the distal part is moved into the stack-releasing position.
