EDWARD H. ROY, OF LOUISVILLE, KENTUCKY.

REFRIGERATOR.

incase-f. Y

T0 @ZZ whom t may concern Be it known that I, EDWARD H. ROY, citizen of the United States of America, residing at Louisville, in the county of Jefferson and State of Kentucky, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

This invention relates to refrigeration and has special reference to an improved ice-box.

One important object ot the invention is to improve the general construction of devices of this character.

A second important object of the invention is to provide an improvement on the refrig'erator for which application for patent has been previously iiled by me, the saine bearing the Serial Number L169,235 and being led on the thirteenth day of May, 1921.

A third important object of the invention resides in providing an improved arrangement of box having a removable ice container.

A fourth important objection of the invention is to provide a refrigerator having an improved removable ice container so constructed and arranged as to provide a wall of ice about the sides and over the top of the cooling or refrigerating chamber proper.

A fifth important object of the invention is to provide a refrigerator of this class wherein the improved ice chamber may be spaced from the inner wall of the re'lrigera` tor casing whereby an air space may exist between the ice container and suchl inner walls.

A further obj ect of the invention is to provide an improved ice-box of this character wherein the ice chamber has both drawoff and over-flow pipes.

lVith the above and other objects in view, the invention consists in general of certain details ot construction and combinations oi parts hereinafter fully described, illustrated in the accompanying drawings, and specifically claimed.

In the accompanying drawings7 like characters of reference indicate like parts in the several views, and

Figure 1 is a vertical median section through an ice-box constructed in accordance with this invention.

Figure 2 is a section on the line 2 2 of i Figure 1.

Figure 3 is a perspective view partly broken away and showing the removable ice compartment.

28, 1921. Serial No. 518,335.

In the invention herein illustrated there is provided outer heat insulating casing and an inner ice ieceptacle. This outer casing is substantially identical with the outer casiiigof my previously described application having inner and outer walls 10 and 11 which are held apart by suitable spacing blocks 12 so that between these inner and outer walls there may be a packing of heat insulating material such as sawdust, flax tow, asbestos or any other like material as indicated at 13. These inner and outer walls are preferably constructed of wood.

The ice compartment is arranged to be iilled from the top and in order to accomplish this the top of the outer casing is provided witlia plurality of inverted :trustopyramidal openings or hatchways which are normally kept closed by suitable doors or hatches 14k constructed in all respects as is the bo-dy of the casing, being provided with inner vand outer walls, separating members and ,insulating packing. Protecting the bottom inner wall isa metallic floor 15 and box extends a drain pipe 16 having an intake end leading from the looring as at 17, this intake end being of inverted truste-conical form. At the front of the box there is provided a door 18 constructed similarly to the hatches and having the usual hinge mounting 19 at one side and latch 20 at the other.

The ice receptacle proper is preferably made ot metal and has an inner side wall 21 and an outer side wall 22 which are braced by suitable angle irons 23. It will be seen that these angle irons are arranged in staggered relation on the inner and outer walls of the ice-box and that they not only stiffen the iccbox walls but also act to prevent lat eral movement ol the ice during filling and when it is melting. These inner and outer side walls are spaced to provide an ice receptacle and as this removable ice-box extends around tlie packing and along the sides o't' the main refrigerator casing the ice-box or receptacle is in plan of substantial U- shape, the legs of the U being closed as at 24. This box is supported on legs 25 resting on the ioor 15 and the sides and back of the box are closed by a. bottom 26, the front of the box opposite the door 18 being open as clearly shown in Figure 3. Thus between the legs of the ice-box there is provided a reiiiigerating space` 27 and this space is closed at the top by a metallic sheet 28 carried by the inner vall of the ice-box. It is to be noted that the outer wall 22 ot the icebox is spaced from the inner Wall 10 of the casing` and that the hatches 1&1 are supported on a removable cross-bar 29, the spacingand the sides of the hatches being` such that the ice-bon or receptacle proper may be removed Y in this way.

In order to d ain the melted Water from the ice receptacle there 1s provided at the bottom of one leg,` a valved drain pipe Awhich is positioned over the mouth 17 and similarly in order to drain the over-flow water which may exist by reason ot' inattention beingpaid to the drain 30, there is provided a drain pipe 81 which extends up to lthe top 2S and also empties into the mouth 17. Y

In operation the hatches are removed and the ice is packed in the legs of the ice receptacle and also over the top 2S thereof and the hatches are replaced. (Food or other ari ticles to be refrigerated may be placed inthe box through the door in the usual manner.)`

Villienever it is desired to remove' the ice receptacle bodily the hatches 141- and cross- .bar 29- are all removed whereupon the ice receptacle will be lifted directly out. Y

Itis to be observed tliatthe various parts of the body of the outer casing are held to-l gether by bolts as shown iny Figure 2, the casingthus being sectional in construction. Y By this means the outer casing can be disassemvention without departing from the materialV principles thereof. It is not therefore de-l sired to coniinethe invention to lthe exact form herein shown and described, but it is wished to include all such as properly come within the'scope claimed.

l-lavin` thus described the'i1ivention,i\*l1at i is claimed as new, is-

In an ice-box of the kind described, anl

outer casing having a front door and filling housings in the top, anice receptacle substantially U-shaped in plan mounted Within theoutei` casing and having the open end of vthe U opposite the door, said ice receptacle having` spaced inner and outer Walls, the space within the inner ivall forminga refrigerating chamber, a top'flor the refrigerating chamber carried by said inner Walh and anv gle irons on the proximalV surfaces of the innerand outer Walls'of the ice receptacle for stitfening and hindering lateral movement of the ice in said receptacle.

- In testimony whereof l a-ihx, my signature.
