THoMAs' EDWARD PUGI-I', or REGINA, SASKATCHEWAN, CANADA.

REFRIGERATOR.

To all whom it may concern:

Be it known I that .I, THoMAs EDWARD. Been, a subject of the King of Great Britain, and a residentof the city of'Regina, in the Province of Saskatchewan and Dominion of Canada, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification. I

This invention relates to improvements in refrigerators and the objects of the invention are to dispense withthe use of ice and permit or the like, being utilized, to facilitate circulating the coo-ling medium around the cooling chamber, to render the refrigerator simple of construction and generally to adapt it to better perform the functions required of it.

For a complete understanding of my invention reference is made to the accompanying drawings in which Figure 1 is a perspective view, partly sectional, of the improved refrigerator.

Fig. 2 is a transverse section of the improved refrigerator.

Like characters of reference refer to like parts in the several figures.

Referring to the drawings, A represents the improved refrigerator comprising an inner casing inclosing the cooling chamber 10, which is surrounded by an outer casing 11, carried by suitable supports or legs and spaced therefrom to provide a water or like jacket 12. The casing 10 may be supported by the transversely extending wvall member 13, which is provided with a plurality of perforations 14 and in the embodiment illustrated this member is formed in two portions to permit of the inlet water pipe 15 projecting into the said jacket.

This jacket is divided into an upper and lower compartment 17 and 18 by the partition 19 which extends completely around the cooling chamber 10 and terminates at the doorway 20. Communication between the upper and lower compartments 17 and 18 is maintained by the transversely extending pipes 21 and 22, each having one end offset to extend through the division walls 19, thereby communicating with the upper compartment, while the other end remains straight and extends through the lateral wall of the cooling chamber 10 to communicate with the lower compartment 18.

By reference to Fig. 2, it will be seen that the offset ends of the pipes are located on Specification of Letters Patent.

of a cooling medium, such as water- Patented Dec. 31, 1918.

opposite sides of the cooling chamber 10,

thatthere is-no possibility'of the cooling medium remaining dead in the lower com. partment, but on the other hand, a complete positive circulation takes place throughout the jacket 12.

In the embodiment illustrated, the pipes 21 and 22 are shown extending transversely of the cooling chamber but they may be placed longitudinally depending on the ease with which the shelf 23 may be positioned,

the pipes thus performing a dual function of cooling the chamber and supporting the shelf.

The doorway 20 of the cooling chamber 10 extends through the lateral .wall of the casing 11 and is closed by a door 24: which carries a screening 25 on the inner face thereof, the outer face of thedoor being recessed as shown at 25 to engage with a second doorway 26 carrying a glass panel 27 therein.

The doorway 26 is made removable and is held in position by buttons 28 or the like i which permit of its ready removal so that air circulation. can take place throughout the cooling chamber.

The circulating cooling fluid after passing through the upper and lower compartments 17 and 18 of the refrigerator is discharged through the pipe 29.

The assembly of the refrigerator may be readily understood from the foregoing description.

When the refrigerator is in use, the pipe 15 is connected to a water main and the water is turned on. The water on entering the jacket 12 circulates through the lower compartment 18 and passing through the pipes 21 and 22 enters the upper compartment 17, where after circulating therearound is discharged through the pipe 29.

By utilizing the pipes 21 and 22, the interior of the chamber 10 is further cooled and a positive circulation of the water or cooling fluid through the compartments 18 and 17 is maintained.

Should it be advisable at any time to ventilate the refrigerator, the removable door 26 may be removed, so that while the air is permitted to flow through the screening 25, there is no possibility of insects, such as flies or the like entering the refrigerator.

From this description it will be seen that I have invented a refrigerator which can be advantageously utilized in districts where a supply of ice is difficult to obtain, the construction of the refrigerator being such that there is nothin to get out of repair, so thatthe operation 0 the refrlgerator 13 not liable to become impaired in any manner.

As many changes could be madein the above description and many apparently Widely different embodiments of my inven- 7 tion Within the scope of the claim constructed Without departing from the spirit or scope thereof, it is intended that all matter contained in the accompanying specification Oopies of this patent may be obtained for ing space around the inner casing, a horizontal partition forming upper and lower compartments in the liquid circulating space, a perforated Wall dividing the space beneath the cooling chamber vertically, an inlet pipe for Water, and an outlet pipe 29 and circulation pipes 21, 22', extending through the cooling chamber and having at one end offset portions extending through the partition and at the other end communicating With the lower. compartment for allowing the Water to flow from the com-' partment beneath the partition 19 to the compartment above the same, substantially as described. In Witness whereof I have hereunto set my hand. v THOMAS EDWARD PUGH.
