ABSTRACT:
A metering mechanism for a paper towel dispenser cabinet is disclosed. The metering mechanism includes a metering gear which is rotatably driven by an operating mechanism of the dispenser cabinet. The metering gear has an axially extending cam portion which defines a radial cam surface extending continuously around the axis of the metering gear from a larger radius to a smaller radius and an abutment wall adjacent to the larger radius end of the cam portion. The metering gear also has an integral resilient finger adjacent to the abutment wall which is biased out of the plane of the metering gear. A release means is urged toward the axis of the metering gear and engages the abutment wall in a stopped position to inhibit rotation of the metering gear and thereby inhibit operation of the dispenser. The metering gear is released for rotation by moving the release means past the abutment wall until the spring finger snaps out of the plane of the metering gear to hold the release means clear of the abutment wall in a dispensing position ready to follow the cam surface. As the metering gear is rotated, the release means follows the cam surface from the larger radius to the smaller radius and eventually returns to the stopped position to once again stop the operation of the dispenser.
