To all whom it may concern:

Be it known that L-CHARLES MoCoY, a citizen of the United States, residing at Wmnipeg, in the Province of Manitoba, D0

minion of Canada, have invented a new and useful Cooler for Refrigerators, of which ing in contact therewith will be cooled and my lmproved refrigerator with the doors of.

forcibly hurled therefrom to thereby create a forced draft of cooled air within the refrigerator.

A further object is to provide an improved form of rotatable tank adapted to contain a freezing mixture therein whereby the said mixture will be agitated to lower the tem perature thereof. 7 I.

With the foregoing and other Ob ects-m view which will appear as the description preceeds, 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 inthe precise embodimentof the invention herein disclosed, can be made within the scope of what-is claimed, without departing from the spirit of the invention.

In the drawings accompanying this specification and forming a part thereof, the preferable form of my invention is illustrated, in which Figure 1 isa front view in elevation of the cooling compartment open to disclose thecooling means disposed therein. Fig; 2 is a plan view of the tank. Fig. 3 is a fragmentary vertical cross sectional view taken throu h the center of the said tank.

tratedin Fi l of the drawings in an open position. T 'e' improved cooling apparatus herein described is illustrated in the ice compartment 2 but it is to be understood that it may be applied with equal facility to refrigerators, ice boxes, or cold storage rooms, etc, taking the place of the ice which is ordinarily disposed therein.

The cooler into which the freezing mixture and ice is placed comprises the central portion 4 communicating with which and extending therefrom are the four wings 5. Each of the said wings is provided with a hingedly mounted lid or cover 6 with a: suitable latch 7 secured thereto whereby the cover may be held in a closed position. The cooler which is in the form of a tank or receptacle is provided with the circular flue 8 extending centrally .therethrough and through which flue extends the vertical shaft 9 which is adapted to, support the said cooler or receptacle in a rotatable manner.

the central portion of the cooler is considerably larger than the shaft 9 so as to provide an air circulating conduit through the central portion of the cooler whereby an .increased radiating surface will be provided in the cooler receptacle.

The shaft 9 is disposed within suitable bearings 10 secured to the upper and lower walls of the compartment 2 and rigidly secured to the shaft 9 adjacent the lower extremity thereof is a belt wheel 11 around which passes the drivlng belt 12, the latter passing over the pulley of a motor 13, whereby the said shaft 9 may be mechanically operated. Rigidly secured to the upper and lower ends of thecooling receptacle 4: are the cross members 14 which are adapted to en gage the shaft 9 and to hold the said cooler receptacle rigidly thereto whereby the same will be rotated by the rotating of the shaft. The motor 13 which represents a source of power is adapted to drive the cooler by gearing or a friction belt 12 which actuates the shaft 9 to thereby rotate the cooler, it being pointed out that the belt is illustrated as a driving mechanism as being .silent in operation and practically noiseless. By rotating the said cooling receptacle, the wings 5 thereof willcome' forcibly against .the surrounding air and will thereb cool the same and create a forced draft w ich will circulate throughout the various portions of the refrigerator to effectual 1y cool the same. The air will also circulate through the centre-'1 lllu flue 8 and will be cooled through the said passage, it being noted that the air will be cooled and at the same time will remain in a dry and sanitary conditioninasmuch as it does not come directly into contact with the ice and freezing mixture which is disposed within the cooling receptacle 5.

The top cover 1s provided with lids 6 communicating with the various wings of the cooler and through which the ice and freezing mixture is to be introduced. The mixture -which is introduced within the said receptacle or compartment of the cooler is adapted to absorb the heat from the walls of the cooler and from the surrounding air. with the result thata considerable lowering of temperature will be obtained and that by a rotatlng of the said cooler, the. various ingredients will more readily pass into solu- =-tion to thereby absorb the heat as described.

'From the foregoing it will be apparent that the rotating of the cooler performs the functions and produces the eflect of increased radiation by bringing the air forci- -'bly into contact with the side walls of the cooler and to create a forced draft throughout the various parts of the refrigerator and also tends to agltate material disposed within the cooler, to aid the same in passing into solution, and to further bring the various materials into more intimate contact' to thereby eflect a lowering of temperature. By extending the four wings 5 radially from the central portion 4, it allows the various ingredients disposed therein to be thrown forcibly against the outer extremities of the said wings' and to thereby produce the greatest cooling effect at these points, and which points are also the ones which being the farthest from the center of the rotating cooler, contact with a relatively greater amountof air than the portions more centrally disposed.

From the foregoing itv will be apparent that refrigeration may be obtained with or 'witliout the use of ice and that furthermore when used in connection with ice, the most eflicient and economical refrigeration will be obtained, it being' pointed out that when it is desired to considerably lower the temperatureat any time, the motor may be started and the same rotating the cooler will agitate the various ingredients disposed within the said cooler to immediately reduce the temperature, as described.

Mention is also made of the fact that the cooler may be used to cool rooms, public buildings, etc.

Havin thus fully described the invention what Iaaim to benew and original with me is:

1. In an'apparatus of the class described,

the combination of a refrigerant receptacle with outstanding wings communicating therewith, a central flue extending longitudinally through the said receptacle and providing an air passage therethrough, a

ed to rotatably support the said receptacle, means for rotating the said receptacle to bring the wings thereof forcibly in contact with the surrounding air to create a positive draft and to cool'the' same.

2. A refrigerant receptacle including a main compartment with a'central flue extendin there through and ositi'oned substantia ly vertical, a plurahty of radially extending wings communicatmg with said main compartment and with't'he longitudinal axes thereof substantially parallel to the longitudinal axis of the said flue, and

means extending through said flue for the supporting of said receptacle.

3. In an apparatus of the class described, a main compartment provided with a central flue extending therethrough, a shaft extending through said flue, and means engaging the said shaft and the said compartment 'for securing the said compartment thereto,

radially extending wings; communicating with the main compartment and with their longitudinal axes substantially parallel to extending through saidflue, means for holding said shaft in a verticalposition, means engaging said receptacle and said shaft for support-ing the receptacle out of contact with adjacent objects and to permit the circulation of air through the said flue, the adjacent surfaces of the walls of the radial wings forming reentrant angles, the said walls acting to cool the air in contact therewith and to set up a circulation of air downwardly past the said walls and up through the central flue.

In testimony that I claim the foregoing as my own, I have hereto aflixed my signature in the presence of two witnesses.
