RE e RATQB- Application filed April 7, 19%. Serial No. 704,8(17.

To all ICIZOWZ it may concern .1

Be it known that I, HUorrr ALEXANDER GRANT, a subject of the King of Great Britain, residing at Malone, in the county of Franklin and State of New York, have in.- vented a new and useful Refriaerator, of which the following is a specification- This invention relates to' refrigerating or cooling chambers.

The object of the invention is to. provide a simply constructed refrigerator in which a maximum cooling efliec-t will be produced with a minimum consumption of ice.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings Figure 1 represents a vertical section taken on the line 1-1 of Fig. 3.

Fig. 2 is a horizontal section taken on the line 22 of Fig. 1.

Fig. 3 is a Vertical section taken in a plane at right angles to Fig. 1 on the line 83 of Fig. 1.

Fig. 4 is a detail of one of the supporting standards of the removal boards in front of the ice compartment.

Fig. 5 is a detail perspective view of the air deflector; and

Fig. 6 is a similar view of the drip pan.

In the embodiment illustrated a chamber 1 is shown having the walls thereof provided with dead air spaces 2 to insulate the contents of the chamber. The floor of this chamber is here shown made of cement 3.

Mounted within the chamber 1 is an ice container 10 in form of a rack 11 with adrip pan 12 arranged below it. This drip pan 12 is provided with an upstanding flange around it and in the bottom thereof has a screened opening 13 from which a drain pipe 14 leads.

Rising from the front of rack 11 at the corners thereof are two angle iron standards 15 equipped with seats 16 to support removable boards 18 which are arranged one above the other as shown in Fig. 3 and held in operative position by keepers or lugs 17 which form stops to prevent the boards falling inward against the ice. These boards 18 are made removable to facilitate the insertion of ice on the rack sothat any desired quantity of ice' may be placed on the rack and held in operative position by the boards, the ice being shown in Fig. 3 by dot and dash lines as indicatedat I. I f I Between the front wall of the ice 'andthe boards 18 is formed a space 19 for the passage of air between said-board'sand the'ice the air entering at the top and passing down against the ice and cooled leaving the ice compartment through the opening 25 at the lower portion of which is arranged, a downwardly inclined air deflector 20. This deflector 20 extends into the ice compartment so that the air impinging thereagainst is directed downwardly into the chamber 1 and rises up to the top of said chamber passing again into the ice container in the manner above described.

The deflector 20 is preferably constructed as shown in Fig. 5 with a downturned right angular flange 21 at its rear wall provided with an inwardly extending apertured lip 22 which forms an attachment for securing the deflector to the rack 11.

Arranged across the front of the ice con tainer outside the boards 18 are a plurality of vertically spacedtransversely extending bars 23 which are equipped with hooks'Q-i on which are designed to be suspended meats or other articles to be cooled.

In the use of this refrigerator the hot or warm air entering the top of the ice compartment impinges against the ice at the upper portion thereof thus causing it to melt along the dotted line shown at 26 the air getting cooler and cooler as it descends and finally when it passes out through the opening is sufliciently cooled for the purpose desired and enters the chamber 1 where it contacts with the object or articles therein to be refrigerated.

As the cakes of ice melt at the top of the compartment the top or uppermost board 18 is removed to permit theair to pass over the next adjacent in contact with the ice for the purpose above set forth.

This refrigerator is very simple and easy to construct and will be equally as efliGient as e ore e pensive Onesg I claim 1. A refrigerator comprising a cooling ice, and a downwardly inclined air deflector located within and spaced from said shieldto direct the'cold air toward the floor of the cooling chamber, said shield being formed in detachable sections.

2. The combination with a cooling chamber having an ice rackv mounted therein with a drip pan located beneath said rack, a plumy own, I have hereto-affixed my signature in-the presence of two witnesses.

ralityof boards superposed edgewise one above the other in front of said rack and 1e movably mounted, forming a sectional ice shield, the lowermost board being spaced above the rack, a cold air deflector located below said board and extending in planes on opposite sides thereof, said deflector being inclined downwardly toward the front thereofi. a o p 3. The combination with a cooling chamher having an ice rack mounted therein above the floor thereof, standards rising from the fro'nt 'c'orners of said rack, said inward movement, and a space formed between said seats and the rack to provide an outlet for the cold air from the ice chamber. In testimony that I claim the foregoing as HUGHT ALEXANDER GRANT; Witnesses: r.
