ABSTRACT:
In a wall or other vertical surface mounted dispensing apparatus which receives a tube of viscous material has a base which supports a pair of substantially vertical gear tracks for receiving a cylindrical roller which has a plurality of gear teeth about the periphery at each end of the roller for engagement with said gear tracks. The roller is provided with a handle mounted on and axle which is rotatably attached to the roller through end caps which maintain the axle along the central axis of the roller but permit rotation relative to the roller. A cover holds the roller in place by exerting pressure on the cylindrical surface adjacent to the peripheral gears. The axle engages a pair of weights a point offset free the central axis of the weight which cause rotation of the crank arm in the upwards direction when released. A recoil arm mounted on a rectangular section of the axle is displaceable along its longitudinal axis. At the end of said recoil arm opposite said rectangular housing is a pawl for engaging saw tooth edges disposed annularly about the inner periphery of the roller. The operation of the crank arm downward caused a rotation of the roller along the gear track and the resulting pressure on the tube expels the contents of the tube out of a supply tube port which may be selectively sealed and unsealed. When the crank arm is released the weights will cause the crank arm to be moved to a ready position and the dispensing apparatus will be ready for the next operation.
