July 11, 1933. J. LOEB COOLING CHEST FOR FOODSTUFFS I ll Hw- +|m ATTORNEY ill x l! Filed Jan. 6, 1933 Patented July 11, 1933 UNi'rEo STATES JULIEN LOEROF BROOKLYN, NEW YORK V COOLING CHEST FOR FOODSTUFFS Application filed January GH, 1933. Serial 110,650,397.

The object of the present, invention is to provide a cooling chest for foodstuffswhich shall be used in conjunction with and supplementary to the present-day automatic refrigerator, electric and gas, and so designed as to receive a tray. of ice cubes from the automatic refrigerator, the latter serving to maintain thecontents of the chest cool for a period of from twelve to twenty-four hours.

The invention will be described with reference to the accompanyingdrawing in which Fig. 1 is a sectional plan View on the line 11, Fig. 2 showing an embodiment of the invention,

Fig. 2 is a front elevation of an embodiment of the invention.

Fig. 3 is a fragmentary section through the top wall of the chest showing in perspective a tray rack.

Fig. 4 is a fragmentary horizontal section through a corner of the chest showing the relation between a door abutting wall.

Fig. 5 is an end elevation of the chest with the end wall partly broken away. I

Referring to the drawing, it will be seen that the chest comprises a rectangular casing composed of end-walls 1, a rear wall 2, top and bottom walls 3, 3a respectively. These walls may be formed of spaced sheets of metal enclosing insulating material indicated at a.

To the under-face of top wall 3 is secured a rack t formed of a piece of'metal bent roughly U-shaped with horizontal flanges 4w apertured to receive rivets or screws 5.

The casing is provided at its front with a door 6 hinged at 7 so as to be movable upwardly. The door is provided at its lower end with a swinging catch-lever 8 adapted to engage catch member 9. The door has pivoted thereto at 10 a bracket arm 11 having a slot into which projects a pin 12 carried by a side wall of the casing.

When the door is swung upwardly, bracket arm 11 assumes dotted-line position, Fig. 5, a shoulder at the rear end of the slot engaging the pin and holding door 6 upwardly until.

the bracket arm is given a slight vertical movement to carry the shoulderv of the slot out of register with the pm.

In the operation of the chest, a tray of ice cubes will be removed from a refrigerator and placed in rack 4 whereupon foodstuffs may be placed in the chest and the door closed. Circulation of air is permitted by 55 the fact that the rack at is of greater depth than the tray, the normal top of the tray being indicated by the dotted lines 6, cold air being permitted to pass downwardly and outwardly from the rack through aperture 0 at the base of the rack and through spaces intermediate the rear wall of the chest and flanges 400 which serve as stops for the rear end of the tray.- r

At the end of the normal cooling period, 65 at which time the icein the cube tray will be melted, the tray may be removed, replaced in the refrigerator and a new tray ofcubes placed in the rack of the chest. Duringthe meltingof the ice the water accumulates and is retained within the tray without the necessity for apipe or other means to effect out-flow of the water after the ice melts.

My cooling chest may be placed in any c011- venient positon, as, for example, on or adjacent the refrigerator, and serves to increase the preserving capacity ofthe refrigerator without affecting the operation of the latter in any respect.

i It will be understood that the device, 315

though primarily a cooling chest, may be employed with reverse operation, i. e., as a heating chest. For example, a heating element may be placed withinthe chest in substitution ofa'nf ice tray and the chest used to maintain food warm. f

Having described my invention, what I claim and desire to secure byLetters Patent, is as follows 1. In combination with an automatic re-. frigerator having an ice-forming compartment and a plurality of sectional trays therein, each adapted to hold water frozen into ice cubes by the refrigerator, of a coolingchest comprising a closed heat-insulated walled casing provided with a front wall formed as a hinged door, a rack carried by the chest and a tray for containing ice cubes received by said rack, the tray being interchangeable with a tray of ice cubes in said refrigerator,

sage, and a stop device limiting the rearward movement of the tray to expose lateral air passages at the rear of said side Walls.

In testimony whereof, I have signed my name to this specification.

JULIEN LOEB.
