COCKS, F DES MOINES, IOWA, ASSIGNOR 03F ONE-HALF T0 NATHANIEL C. BARNES, OF DES MOINES, IOWA DISPENSING APPARATUS Application filed October 29, 1927. Serial No. 229,598.

The object of my invention is to provide a dispensing apparatus wherein liquid soap or creams may be dispensed with regular shots or charges, the parts being simple, durable and comparatively inexpensive in construction.

More particularly it is my ObJGCt to provide an inner container within an outside container wherein air pressure may be, used for forcing the bottom of the inside container upwardly wherein the contents from within the inside container, may be discharged and dispensed by manually operating a valve controlled outlet.

Still a further object is to provide a pump mechanism forming a part of the dispensing apparatus wherein the inside container may be subjected to air pressure for causing lts bottom to move and thus discharge the contents from within the inside container when desired.

Still another object is to provide an 1nside container having a movable bottom therein arranged with a downturned flange so that a chamber is formed below the bottom of the inside container and the base of the dispensing apparatus for receiving a sufcient amount of air under pressure to move the bottom upwardly when the valve controlled outlet is in open position.

With these and other objects in view,-my invention consists in the construction, arrangement and combination of the various parts of my device, whereby the ob'ects contemplated are attained, as hereina er more fully set forth, pointed out in my-claims, and illustrated in the accompanying drawings, in which Figure 1 is a top plan view of proved dispensing apparatus.

Figure 2 is a central vertical sectional view taken on the line 22 of Figure 1.

Figure 3 is an enlarged detail view of the check valve forming a part of the pump construction and mounted in the base of the dispensing apparatus.

Figure 4 is a perspective view of the bottom element which is mounted within the inside container and Figure 5 is a perspective view, parts being my im- 24 in communication 18 of the plug 20 and broken away and shown in section, disclosing the assembly of the bottom and the inside container. 7

In the accompanying drawings, I have used the reference character A to indicate generally a base having a cylinder opening 10 formed therein. The cylinder opening 10 is partially closed at one end with a cap or plug 12 and has a narrow web 14 formed in its other end. The web 14 is provided i with an opening 16 adapted to communicate wlith an opening 18 formed ina check valve p ug 20.

The plug 20 is adapted to be screw threaded into the base A and is provided with a ball valve 22. The base A has a passageway with the passageway serves as a means of communication between the pump construction and the interior oi: the dispensing apparatus as will hereafter be more fully set forth.

S lidably mounted within the plug 12 is a piston rod 26 having a piston 28 mounted thereon. The stem or rod 26 is formed with a screw threaded end 30 which may coact with screw threads formed in the plug 12 whereby the pump construction may .be closed or locked against movement.

The inner end of the stem or rod 26 is formed with a pointed end 32 which pro- ]ects into the opening 16 in the web 14 for closing it when the pump is in inoperative position. Operation of the pump will force air through the passageway 24 against the ball valve 22 into the interior of the dispensing device. t

The cylinder 10 is, of course, open to atmosphere by means of openings 34 formed in the plug 32. The base A has mounted thereon, an outside chamber 36. The lower end of the chamber 36 rests upon a gasket or seal 38. The chamber or casing 36 may be provided with any meansof connection between itself and the base A.

I have provided an outturned flange 40 which extends a short distance around the casing 36 and which coacts with a similar flange 42 formed upon the base A whereb the casing 36 after it is set upon the base may be turned a quarter turn and the flanges T e outlet B is formed with a downward 1y extending spout 52. The passageway 44- is in communication with the valve B. Within the outside casing 36 I mount an inner container or casing 54 made of paper or any other suitable material.

The container 54 is provided with an upturned inwardly extending flange 56. A bottom 58 is mounted within the container 54 and has .a downwardly extending flange 60 adapted to rest against the inner wall of the container 54 and to coact with the u turned flange 56 thereof as clearly shown in Figure 5 of the drawings. It will be noted that the bottom 58 1s positioned a short distance above the lower end of the container 54 so that a chamber or air receiving pocket 62 is formed above the base A and below the bottom 58. The passageway 54 in the base-A is in communication with the receiving pocket 62.

Within the container 54 may be placed substances of semi-liquid nature such as shaving cream, cleansing cream, tooth paste and the like. v

The contents from within the container 54 is forced upwardl by means of the air pressure ap lied against the bottom 58. This in turn lls the passageway 44 and the valve element B with the substance or contents.

Inward movement of the valve control 48 manually, will allow a certain amount of the contents to pass around and through the 1 valve seat 50 into the spout 52 where it will be dispensed. Pressure of the contents within the chamber 54 against the valve or con trol element 48 causes it to assume a closed position.

It will thus be noted that the element 48 is opened manually and closed automatically by the pressure ofthe contents within the container 54. Movement of the valve element 48 is of course limited by the head or knob formed thereon which engages the spout or outlet B;

Practical operation In the practical use of my device, it is only necessary to take a container as represented in Figure 50f the drawings and place it within the casing 36. The pump mechanism is released and thereafter reciprocated until air pressure is acquired within the receiving pocket 62.

The check valve 22 permits the air pressure accumulated within the pocket 62 to remain dispensed in suc pump may be locked against further operatlon.

tents within the container under pressure and whenever the valve element 48 is moved to open position, the contents will be discharged.

My device is especially applicable for use in barber shops and the like where shaving cream may be purchased in considerable volume, placed in m dispensing apparatus and amounts as required for shaving purposes.

Some changes may be made in the construc- The action just referred to places the con-,

tion and arrangements of the parts of my device without departing from the real spirit and purpose of my invention and it is my intention to cover by my claims, any modified forms of structure or use of mechanical e uivalent's, which may be reasonably include within their scope. I I claim as my invention 2-- i.
