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.

A dispensing apparatus for dispensing the contents of at least one flexible tube having an opening and containing a viscous substance, said dispensing apparatus comprising: a. a base having a plurality of gear tracks spaced apart to provide a space for receiving the tube, b. means for supplying the contents of the tube adapted for communication with the opening of the tube, c. means for applying compression to the tube, said means including gear teeth for engaging said gear tracks and an axis, d. a cover removably engaging said base, said cover including means for holding said compression means against said base when said cover engages said base such that said gear teeth of said compression means are in communication with said gear tracks of said base, and e. means for selectively rotating said compression means about said axis only in a first direction whereby said gear teeth engage said gear tracks to advance said compression means along said gear tracks to apply compression to the tube and dispense the contents from the tube, said rotating means including an arm and being mounted for reciprocal rotation in said first direction while said arm engages and rotates said compression means therewith in said first direction and in a second direction opposite to said first direction while said arm disengages said compression means and said compression means remains relatively stationary, said rotating means being manually graspable to be manually driven in said first direction.
