Wall-mounted soap dispenser
First Claim
1. A dispenser for liquids, pastes, and creams capable of being mounted on a vertical surface comprising:
- a manual pumping mechanism including,a pump housing providing a reservoir for liquid,a pump chamber within said pump housing having at least one connecting opening to said reservoir, having a smaller chamber segment nearer the front of said mechanism and a larger chamber segment behind and co-axial with said smaller chamber segment, having a dispensing opening in said smaller chamber segment,a piston having a smaller piston segment and a larger piston segment behind and co-axial with said smaller piston segment, having a piston rod on the end of and co-axial with said larger piston segment, having grooves on each of said piston segments with gaskets fit into said grooves so as to form a sliding-contact fit between said chamber segments and said piston segments, said piston rod having at its end a crossbar,a lever pivoted at its upper end from the rear side of said pump housing and attached near its middle to said piston rod, said lever having a slot adapted and constructed to fit said piston into said lever, said crossbar having a flat at one end, said lever having a stop on its back side adapted and constructed so that after inserting said crossbar through said slot and rotating said crossbar by ninety degrees, said flat rests against said stop,a spring means forcing said lever toward the rear of said dispenser, anda means for attaching said mechanism to a vertical surface.

Abstract
A wall mounted soap dispenser made of plastic is described. The dispenser includes a hand-operated pump which dispenses liquid soap under pressure and which can be manufactured inexpensively. A disposable container of liquid soap is inserted in the dispenser to refill the dispenser. The pump has on its top a pan to collect liquid spilled as the disposable container is inserted. The pump and container are enclosed in a plastic housing which hinges from a plastic wall plate. A plastic latch with plastic key is used to lock the housing to the wall mounting plate. The pump mechanism uses a piston of two sections of different diameter and corresponding piston chamber of two sections of different diameter. There is an adjustable piston stroke length limiting mechanism. The piston is attached to the lever which moves the piston by means of a crossbar on the end of the piston rod. The crossbar is inserted in a slot in the lever and then turned to cross the slot.
