Abstract

A cabinet forms a frame mounting a dispensing mechanism, a soap reservoir comprised of a sump and container, and an actuating lever, all of which are selectively removable from the frame for maintenance purposes. The dispensing mechanism and reservoir sump are formed unitary slideably connected to the frame with the actuating lever pivotally connected partially overlying the dispensing mechanism in cantilever extension vertically pivotal by a forward broadened hand engaging portion to actuate the dispensing mechanism therebeneath. The reservoir container is supported inverted on the reservoir sump emptying downwardly therein and partially forwardly overlies the actuating lever, being forwardly supported to prevent the container from inadvertently depressing the actuating lever dispensing soap from the dispensing mechanism when the container is removed forwardly and replaced rearwardly to replenish the soap supply. Stroke adjustment for the actuating lever may be provided to adjust the soap volume dispensed on each lever stroke and soap flow adjustment to the dispensing mechanism may be provided increasing or decreasing time required between lever dispensing strokes. Also, the soap discharge end of the dispensing mechanism nozzle may be provided with projection means preventing nozzle closing off by an operator'"'"'s finger.

Claims

1. In a dispenser for dispensing flowable soap, and dispenser being of the type having a frame mounting a selectively operable dispensing mechanism for dispensing soap therefrom and a reservoir operably connected to said dispensing mechanism for supplying soap thereto to be dispensed;

the combination of;

a generally horizontally projecting dispensing lever extending in cantilever fashion and having rearward end means pivotally attached to said frame for selective vertical pivotal movement of said lever in actuating strokes, said lever having at least a part overlying said dispensing mechanism and having actuating means spaced forwardly of said rearward end means and operably connected to said dispensing mechanism for operating said dispensing mechanism during pivotal actuating strokes of said lever;

said reservoir including a sump operably connected to said dispensing mechanism for supplying said soap to said mechanism, a selectively removable container positioned on and projecting generally vertically from said sump supplying soap to said sump, said container at least partially overlying said dispensing lever;

said dispensing lever extending forwardly between and being selectively vertically pivotal between parts of said container and said dispensing mechanism during said lever pivotal actuating strokes, a forward end of said actuating lever being forwardly exposed of said container and dispensing mechanism accessible for hand engagement to carry out said lever pivotal actuating strokes.

2. In a dispenser as defined in claim 1 in which upward pivotal movement of said dispensing lever in said lever pivotal actuating strokes is limited by stationary stop means upwardly engageable by said lever during said pivotal actuating strokes between said container and said dispensing mechanism preventing lever contact with said container.

3. In a dispenser as defined in claim 1 in which said rearward end means of said dispensing lever includes transversely spaced leg means rearwardly pivotally attached to said frame and forwardly secured to a transversely broadened hand engaging portion of said forward end partially overlying said dispensing mechanism, said lever actuating means being secured to a rearward part of said lever hand engaging portion and projecting downwardly to engage and operate said dispensing mechanism during said pivotal actuating strokes of said lever between said container and said dispensing mechanism.

4. In a dispenser as defined in claim 1 in which stationary support means projects above said dispenser lever engageable by said container at least during insertion and removal of said container effectively preventing said container from pivotally moving said lever and causing inadvertent soap dispensing during said container insertion and removal.

5. In a dispenser as defined in claim 1 in which support means projects above said dispenser lever engageable by said container at least during insertion and removal of said container effectively preventing said container insertion and removal from pivotally moving said lever and causing inadvertent soap dispensing during said container insertion and removal, said support means including at least one stationary post extending generally vertically adjacent said lever.

6. In a dispenser as defined in claim 1 in which support means projects above said dispenser lever engageable by said container at least during insertion and removal of said container effectively preventing said container from pivotally moving said lever and causing inadvertent soap dispensing during said container insertion and removal, said support means including two transversely spaced stationary posts extending generally vertically adjacent said lever and upwardly engaged with said container.

7. In a dispenser as defined in claim 1 in which said dispensing mechanism includes a discharge nozzle with said mechanism being operable for dispensing soap axially through at least one discharge opening in an end of said discharge nozzle;

and in which said nozzle end has a generally radial outer surface forming axial termination of said discharge opening and projection means extending axially from said generally radial outer surface radially displaced from said discharge opening for preventing blocking of said discharge opening and permitting said soap axial dispensing even though a generally radial abutment may be placed axially against said nozzle end such as an operator'"'"'s finger which would otherwise close off said discharge opening.

8. In a dispenser as defined in claim 1 in which said dispensing mechanism contains a constant quantity refillable soap volume normally discharged by each selected operation of said dispenser, said reservoir sump supplying soap to said dispensing mechanism to refill said constant quantity soap volume, a flow opening formed between said reservoir sump and said dispensing mechanism automatically directing a flow of soap from said sump to said mechanism at least between said selected operations of said dispenser for said refilling;

and in which flow opening valve means at said flow opening is selectively adjustable for selectively closing off greater or lesser portions of said flow opening to decrease or increase timed rate of soap flow between said reservoir sump and said dispensing mechanism and thereby extend or shorten the time required for the dispensing mechanism to be refilled and thereby receive said constant quantity refillable soap volume.

9. In a dispenser for dispensing flowable soap, said dispenser being of the type having a dispensing mechanism containing constant quantity refillable soap volume normally discharged by each selected operation of said dispenser, a reservoir for supplying soap to said dispensing mechanism to refill said constant quantity soap volume and a flow opening formed between said reservoir and said dispensing mechanism automatically directing a flow of soap from said reservoir to said mechanism at least between said selected operations of said dispenser for said refilling;

the combination of;

flow opening valve means at said flow opening selectively adjustable for selectively closing off greater or lesser portions of said flow opening to decrease or increase timed rate of soap flow between said reservoir and dispensing mechanism and thereby extend or shorten the time required for the dispensing mechanism to be refilled and thereby receive said constant quantity refillable soap volume;

said dispensing mechanism including a cylinder having said constant quantity refillable soap volume therein with said flow opening being formed through a side of said cylinder;

said valve means at said flow opening being outward of said side of said dispensing mechanism cylinder and being rotatably mounted on said cylinder side at least partially within said reservoir.
