ApplicatîOn May 10, 1945, Serial N0. 593,065 6 Claims. (Cl. 222-340) ‘ A1 This invention appertains to liquid dispensers and more particularly to a novel device for dis pensing a measured quantity of liquid soap upon each operation thereof by a user. One of the primary objects of my invention is to provide a liquid soap dispenser of the type embodying a supporting bracket and a bowl orA jar for the soap connected with the bracket and having a novel pump mechanism for delivering the soap from the bowl directly into the hand of the user. Another salient object of my invention is to provide a novel pump mechanism for liquid soap dispensers in which the necessity of packing washers, gaskets and the like is eliminated, there by insuring the effective operation of the pump at all times. i ` A further object of my invention is to provide Figure 2 is a- sectional view taken at right angles to Figure 1 and substantially on the line 2_2 of Figure l looking in the direction of the arrows. Figure 3 is a top plan view of my ¿improved soap dispenser. Figure 4 is a detail vertical sectional view ` taken on the line 4-4 of Figure 1, looking in the direction of the arrows and illustrating a partY of the bracket.

The lower end of the provide a liquid soap dispenser which` will be face plate can be'provided with an opening I6 extremely durable and eñìcient in use, and one reasonable cost. i With these and other objects in view, the in vention consists in the novel construction, ar rangement `and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawing, in 50 which drawingz' , Figure l is a vertical sectional View through my improved liquid soap dispenser, the section being taken substantially on the line I-I of 55 Figure 2,1ooking in the direction of the arrows. persons willbe prevented. Extending forwardly from the face plate I3 is the body portion I8 of the bracket, and this body portion has formed thereon and depending therefrom, an internally threaded sleeve I0 for the reception of the neck 20 of the bowl or jar IIL The thread'ZI formed on the neck of the bowl or jar Il can be inter rupted as at 22 and a machine screw 23 can be threaded into the bracket and into the inter-` 2,407,765 rupted portion of thel thread 2l so as to prevent the accidental displacement, or removal by un authorized persons, of the bowl Il from the bracket. The bracket has formed therein a ver tically disposed filling opening 24 which corn municates with'the interior of the sleeve I9, and consequently with the bowl II. Hence, the bowl can be filled through this opening without the necessity of.~removing the bowlfromjthe bracket. A novel closure plug 25 is provided for this opens» ing, and this plug will be later described in de tail. rllhe body portion 'I8 of the bracket also. has formed therein a centrally disp’osedhori zontal bore 26 which bisects the opening 24. This bore 26 opens out both through the front and rear of the body portion of the bracket. If de-` sired, the body portion I8 ofthe. bracket can 4 Referring back to the filling plug 25, it will be noted that the same includes a depending sleeve 42 and this sleeve has formed therein on oppo site sides thereof spiral bayonet slots 43. In plac ing the plug in position, the slots are placed over the plunger 3l and upon the turning of the filling plug, the plunger 3l will ride into the recessed ends 4t of the bayonet slots d3. This will lock the plug in position and' discourage the unauthorized removal thereof. The top wall of the filling plug can be provided with Spanner wrench openings 45 to facilitate the renewal . thereof by an attendant. From the foregoing description, it can be seen that I have provided an especially simple and durable liquid soap dispenser in which the neces sity of packing gaskets and the like is entirely be reinforced by side walls 21 which join with eliminated. Therefore, it can be seen that there the face plate I3. ` ' . are no parts subject to great wear or which will The pump mechanism I2 includes a horizontally 20 have to be removed at stated periods of time. disposed pump cylinderl 2G, and this cylinder is Changes in details may-be made »without> de adapted to slideback and forth on the pump partingfrom the spirit or the scope of my.k inven piston 28. vThis pump piston is carried by a sup tion, but` what I claim as newV is: y ' porting rod 3€), the Lipper end of which is threaded 1.
