WALTER L. DAVIS, OF NASHVILLE, TENNESSEE.

WATER-COOLER.

Application filed September 24:, 1914.

T 0 all whom it may concern:

Be it known that I, WALTER L. DAvIs, a citizen of the United States, residing at Nashville, in the county of Davidson and State of Tennessee, have invented certain new and useful Improvements in Water- Coolers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in water cooling devices and more particularly to those designed for chilling water for drinking purposes.

The primary object of the invention is to provide a cooler, so constructed as to void the necessity of cracking or crushing ice used therein, and to provide a large water space whereby a considerable quantity of water be cooled at one time, thereby improving upon the types of this general character which employ coils for cooling the water. v y

In carrying out the above end, a water receptacle is provided, and an ice receptacle within said water receptacle.

A secondary object of the invention becomes to so construct the ice receptacle as to provide an. inclined surface upon which the water, fed into the device, is discharged, thereby eifectually cooling the same, and to construct said ice receptacle in such a manner as to allow the same to rest solidly on the bottom of the water tank or receptacle.

With the above and minor objects in view, the invention resides in certain novel features of construction and combination herein described and claimed and shown in the drawings wherein:

Figure 1 is a side elevation of a cooler constructed in accordance with my invention; Fig. 2 is a top plan view thereof; Fig. 3 is a vertical section as seen on the line 33 of Fig. 2; Figs. 4c and 5 are horizontal sections as seen on the lines 1--1- and 5-5 of Fig. 3; and Fig. 6 is a side view of the ice receptacle.

In the embodiment illustrated in the ac companying drawings, a water receptacle 1 is shown which is composed of inner and outer shells 2 and 3, and a packing a of insulating material, such as asbestos, between said inner and outer shells. The receptacle 1 is preferably provided with a depending flange or skirt 5 which is located beneath its Specification of Letters Patent.

bottom 6 and which base.

The top of the tank or receptacle 1 is normally closed by a removable cover 7 whose free edge is turned downwardly as seen at 8 and thence upwardly and inwardly as seen at 9 to provide a resilient gripping flange to snugly engage the outer shell 2. Near one edge, the cover 7 is provided with a circular opening 10 from the edges of which a flange 10 extends inwardly. The flange 10 is provided with an annular shoulder 10". A funnel-shaped guide 11 is fitted in the opening 10 with its lower end resting on the shoulder 10, said guide being de signed to receive the neck of a water bottle when the same is inverted, this general idea being common to numerous forms of coolers. In connection with the funnel shaped guide 11, an inverted cone-shaped strainer 12 is preferably employed, it being fitted to the lower end of the guide 11 as most clearly seen in Fig. 3.

Located centrally within the tank 1, is an ice receptacle 13 which, like said tank, is here shown as being cylindrical. By reference to the various figures of the drawings, it will be seen that the upper portion of the receptacle 13, at one side thereof,1is bulged inwardly as seen at 14 whereby to provide an inclined receiving plate located directly beneath the opening 10'and funnel 12. This formation also economizes in space since were it not for the inwardly bulged portion 14-, greater space would be required between the receptacle 13 and the tank 1, as will be evident.

The annular wall of the receptacle 13 is here shown as resting upon the bottom 6 of the tank 1 and as being provided with a plurality of water inlet openings 15, above which a solid bottom 16 is provided. The bottom 16 is provided with a central opening through which an externally threaded drip tube 17 projects, nuts 18 and 19 being provided on said tube and located respectively above and below said bottom 16. As clearly seen in Fig. 3, gaskets are preferably provided between the nuts and the bottom. The tube 17 likewise projects through a central opening in the bottom 6 and receives a jam nut 20 above said bottom and the socket 21 of a drip cook 22, below said bottom, suitable gaskets or washers being preferably interposed between the bottom 6 and the members 20 and 21.

forms a supporting properly held in place at all times. For the purpose of filling the receptacle 13 with ice, without the necessity of removing the cover 7, said cover is provided with a filling opening 23 which is normally closed by an insulated cap'or cover 24.

With the parts as above described, the

operation of the device is as follows: One

or more comparatively large blocks of ice are positioned in the receptacle 13 and the water bottle (not shown) is inverted and positioned in the guide 11, with its neck located in the strainer 12. It will be under stood that the inclined plate directly beneath the strainer 12 has now been cooled by the presence of the ice within the receptacle 13 and that the water discharged through said strainer 12 will thereby be chilled to an appreciable extent. The greater part of the cooling however, takes place after the Water flows into the space between the receptacles 1 and 13, it being understood that said water flows through the openings 15 into the space beneath the bottom 16. The cooled water may be removed at will, through a manually controlled valve or spigot 25 as is common with devices of this character.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that a comparatively simple cooler has been provided which will effectually carry out the objects of the invention and in which comparatively large blocks of ice may be placed. This is a marked improvement over the usual type of cooler employing a cooling coil around which crushed ice must be packed.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

A water cooler comprising a cylindrical water tank provided with a water outlet, an ice receptacle resting on the bottom of said tank and having its top flush with the top of said tank, said receptacle having upright walls spaced from the walls of said tank and having one of them bulged inwardly to provide an inclined receiving plate, a drip discharge from the ice receptacle, a Hat circular cover plate adapted to rest on the top of said tank and the top of said receptacle, said cover plate having an opening disposed above the open top of said receptacle and a circular opening near its outer edge disposed above said inclined receiving plate, the last named opening being provided with an inwardly extending flange having a shoulder, a funnel-shaped bottle guide fitted in said circular opening and having its lower end resting on said shoulder, an inverted cone-shaped strainer fitted to the lower end of said guide, and a lid adapted to close the first-named opening.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
