Application .iuue 14, 1950, Serial No. 168347 4 Qlaims. (Cl. 222-243) This invention relates to a combination pump and containerv for dispensing cream and other liquids.

An object of this invention is to provide a combination pump and container which will be simple, practical and thoroughly durable.

Another object of the invention is to provide a construction of the above character which may he manufactured from inexpensive materials without udue labor costs.

Yet another object of the invention is to provide a construction of the above character which will be sturdy and well able to withstand continuous hard use.

Still another object of the invention is to provide a construction of the above character which may be readily disassembled and reassembled for purposes of cleaning.

Afurther, object of the invention is to provide a constructionof the above character in which the liquid being dispensed is efficiently cooled.

A still further. object of the invention is to provide a construction. which may be adjusted so that measured amounts of liquid are dispensed.

With these and other objects in View, which may be incident to my improvements, the invention consists in theparts. andcombinations to be hereinafter set forth and claimed, with the understanding that the several necessary elements, comprising my invention, may be varied. in construction, proportions and arrangement, without departing from the spirit and scope of the appended. claims.

The. invention accordingly consists of the. features of construction, combinations of elements, and arrangements of. parts, as will be exemplified in the structurev to be hereinafter. described and the scope of the application which will be indicated in the following claims.

In the accompanying drawings, in which is shown one of the various possible embodiments of the invention:

Figurel is a side elevation of the combination pump and: container;

Fig.. 2. is a horizontal section taken on line 2-2 of Fig. 3. illustrating the bottom of the piston and the valve structure;

Fig. 3 is a vertical section taken through the combination pump and container shown in Figure 1;

Fig. 4 is a horizontal section taken on line 4-4 of Fig. 3; and

Fig. 5 is. a view on an enlarged scale of the handle portion of Fig. 3.

Similar reference characters refer to similar parts throughout theseveral view of the drawings.

Referring now to the drawings in detail, the combinationtpump and. container includes an insulated housing, generally indicated at It having a well 12 secured to the bottom a of the inner shell 1% of the housing 10. The side wall of the well 12 is spaced from shell 1% to provide a space for ice or other refrigerant.

A container 14 is positioned within the housing 10 and includes a pump barrel portion I la which is positioned within the well 12. The remainder of the pump, generally indicated-at 16, is mounted on a cover, indicated generally at 18. The dispensing tube 20 is mounted on cover 18 and extends downwardly into the pump barrel portion 14a of container 14. A piston 22 is mounted on the lower end of a rod 24 which is actuated by knob 26, a spring 28 being used to move the rod 24 upwardly after each pumping stroke. On the downward stroke of piston 22, valve ports 48 in piston 22 are covered by closure 50 and liquid is dispensed through tube 20, while on the upward stroke the liquid flows in through ports 48 and fills pump barrel portion 14a. The housing 10 (Figs. 1 and 3) includes inner. and outer shells 10b and which are spaced from each other and which are joined at their upper edges to form an airtight space 11. The space between the shells 10b and 100 is filled with an insulation material such as cork. The well- 12 includes a side wall 12a and a bottom 1212, which is connected'to bottom 10:: of shell 10b in any suitable manner such as spot welding.

The liquid container 14 is cylindrically shaped and is slightly smaller in diameter than the width of shell ltib so that its wall 14b is spaced from housing shell 10b.- Container 14 includes a pump barrel portion 14a which extends downwardly into the well 12, the container being suspended within housing It) by means of an annular flange which extends outwardly over the upper edge of housing 10. Space 30 between wall 12a of well 12 and shell 10b is filled with a refrigerant such as crushed ice before container 14 is mounted within housing It Thus, well 12 serves to keep the ice or other refrigerant from the center of the bottom of the housing to provide a space for the. pump barrel portion 140. When container 14 is mounted on housing 16, the cool air. from the refrigerant in space 30 can circulate around container 14 in space 32 and enter well 12 through holes 34': Also, when the ice begins to melt, water passing through holes 34 comes into direct contact with pump barrel portion 14a and acts as a heat transfer'medium between this portion or" container 14 and the ice. Thus, when drinks are being dispensed from this cmitainer, the liquid within the pump barrel portion 14a is elhciently refrigerated. asloug as there. is :1V refrigerant in space 395 The remainder of. the pump is mounted on cover 13 which includes flange 18a extending downwardly over the outside of housing 10. It will be noted that flange 18a coacts with container flange 140 to keep container 14 centered. within housing 10. Dispensing spout 20 extends through an. opening in cover 18 and is secured to a. ring-shaped. member 36 in any suitable mannensuch asby brazing. T hev dispensing tube 20 passes through an opening 22:: in piston 22 and thus acts as a guide for piston 22. when piston 22 is not. positioned in pump barrel portion 14a. Piston22is connected to the lower end. ofrod 24 in any suitable manner, such as by brazing. Rod 24 extends through anopening' in the cover 18 and its upward movement is limited by ring 38 brazed to rod 24.

The upper end of rod 24'is threaded and a sleeve 40 is mounted on the threaded portion 24a of rod 24' by means of an internal annular flange d2, having a threaded opening therein. Sleeve 4tl-fitsover a sleeve 44 which is. alsov provided with. an internal annular flange 46. The lower endof sleeve id-fit over. a water guard ring 47 soldered to. cover. 18. Coil spring 28 is mountedon rod 24=and isunder compression, at all times between flanges 42 and 46. Thus, rod 24 is at all times resiliently urged upwardly and sleeve 46 is pressed downwardly against cover 18. Upward movement of rod 24 i limited by the engagement of stop 33 with the under surface of cover 18 at all times and rod 24 is actuated by knob threaded onto its upper end.

To permit liquid to flow into pump barrel portion 1411 during the upward stroke of the pump, the piston is provided with three valve ports 48 (Figures 2 and 4). During the pumping stroke, these ports are covered by a valve closure 50 which is mounted on the lower end of rod 24. The valve closure 50 is provided with a slot 50a (Figure 2) of rectangular shape, which is adapted to receive the T-shaped lower end 2% of rod 24. When valve closure 50 is mounted on the lower end of rod 24, the pump must be disassembled. First slot 50a is aligned with the T portion 24b of rod 24 and closure 50 is then moved upwardly until it lies in the same plane as the portion of rod 24 positioned immediately above the portion 24:: (Figure 3). Because portion 24b is cylindrically shaped to fit the enlarged center portion of slot 50a, closure 50 may be rotated 90. At this time a recess 50b in the edge of closure 50 is aligned with the lower end of dispenser tube 20, and thus, when dispenser tube is passed through piston 22 during assembly, it looks closure 50 in position so that it cannot be removed until the pump is again disassembled.

In operation, when rod 24 is pressed downwardly, closure 50 moves upwardly and closes ports 48. The liquid in barrel portion 14a is forced upwardly through tube 20 and is dispensed through its spout 20a. When pressure on knob 26 is released, spring 28 moves rod 24 upwardly. As spring 28 moves rod 24 upwardly, the liquid flows into pump barrel portion 14:: through ports 48, filling it so that the pump is ready for another dispensing stroke. In order to stir the liquid within container 14, an agitator 52 (Figs. 3 and 4) is secured to the pump rod 24 in any suitable manner, such as by soldering. Thi plate efficiently mixes the liquid Within the container as it is dispensed and this insures that an even mixture of liquid will be dispensed.

Thus, it will be seen that a simple, practical, and thoroughly durable combination container and pump has been disclosed. In this device the pump and container are so constructed that the liquid will be efliciently refrigerated at all times. Furthermore, the pump is so constructed that it may be readily disassembled and assembled for cleaning purposes. Thus, it will be seen that the several objects hereinabove mentioned, as well as many others, have been successfully accomplished.

As many possible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative v and not in a limiting sense.
