Y., a corporation of Delaware Original application October 27, 1933, Serial No. 695,398. Divided and this application Septem ber 19, 1936, Serial No. 101,567 1 Claim. (01. 62-1085) This invention relates to ice trays or the like The lower end of lever I8 is rounded and eccen for use in household refrigerators, and constitutes trically pivoted to the lower rounded end of a a division of my application Serial No. 695,398 bracket 2I which extends upward and is riveted ?led October 27, 1933. i > or otherwise secured to the front wall of' the tray 5 It is an object of the present invention to pro body I 2. A spring 22, having the upper end vide a device for facilitating and simplifying the fastened to the ?ange 23 formed at the upper removal of ice trays after the contents of the edge of the front wall of the tray body and the ' same have, been frozen. ' ' » lower end secured to the lever I8, serves to main The invention, together with the objects and the following description taken in conjunction tain lever I8 in the inoperative position shown in Fig. 2. 10 with the accompanying drawing forming a‘faart of tray body I2 is ?lled with water or other matter, 10 advantages thereof, will become apparent from this speci?cation, and of which Fig. 1 is a frag mentary front view of a cooling unit and an ice tray embodying the invention placed therein, and Fig. 2'is a fragmentary sectional view taken on line 2-2 of Fig. 1 illustrating more clearly parts of the device provided on the tray. Referring to the drawing, an evaporator or cool In the use of the above described device, the ' to be'frozen and inserted in the cooling unit I0 of the refrigerator with which the tray is used. With the tray positioned in theycooling unit heat 15 is removed from the tray bottom through the shelf,'due to the production of cold by the cooling unit, whereby any moisture between the tray bot tom and the shelf is frozen, thus ?rmly uniting 20 ing unit I!) of a.‘ household refrigerator ‘ (not . the parts. When it is desired to remove the tray shown) is refrigerated in any desired manner. The cooling unit I0 may be provided with one or more tray receiving compartments, only one of which is shown, in which an ice tray II is placed 25 for freezing the contents of the same. The tray I I includes a receptacle body I2, at the front end of which is provided two bent over extended por tions or abutments to which a tray front I3 may be secured by bolts or other fastening elements I5. This structure is formed at the time of stamp ing the tray, the material at each side of the tray being cut along the line indicated at I6 in order to provide a triangular reenforcemen't at each front outer corner of the tray. The tray front 35 I g is formed with a handle or hand-grip portion I . with its contents, the handle 20 of lever I8 is moved downward whereby the lower rounded end .of lever I8 is rotated eccentrically with respect to the lower rounded end of the bracket 2 I. With such eccentric movement of the lower rounded end of the lever I8 the lower end of the lever bears against the surface of the shelf I1 and 2o, 25' exerts a separating force between the tray body I2 and shelf I'I. When the ice bond between the _ tray and shelf is broken and the ?nger-grip 28 30 is released, the spring 22 returns the parts to the position shown in Fig. 2, whereupon the hand grip I4 can be grasped and the tray removed from the cooling unit. ‘ , In view of the foregoing, it will be seen that 35 an improved device has been provided for facill~ tating the removal of ice traysfrom cooling units. The lower rounded end of lever I8 is normally The tray II rests on the lower horizontal por tion or shelf ll of the cooling unit with the broad ~?at bottom of-the tray in thermal contact with ‘disposed adjacent the bottom of the tray body the shelf to provide a good conductive path for I2. When a rotating movement vis imparted to removal of heat through the tray and shelf. the lower rounded end of lever I8 by pulling down 40 When the tray is ?lled with water, moisture on v the ?nger-grip 20, a portion of the lower rounded the bottom of the tray freezes and forms an ice end extends beyond the bottom of the tray. With bond between the bottom of the tray and the shelf this construction the lower end’ of the lever I8, 45 "which must be broken in order to remove the tray together with the bracket 2|, forms 'a leverage 45 ‘from the cooling unit. ' means which can be extended whereby su?lcient In accordance with this invention an improved. force is provided to separate the tray body from device is provided for breaking the ice bond which is formed between the bottom of a tray and the 50 shelf of a cooling unit upon which it is placed. Referring to Fig.2, the device shown includes a lever or bar I8 which extends through a slot l9 formed in the hand-grip portion I 4 of the tray front and is provided with a curved upper end 28 55 to provide a ?nger-grip for actuating the device, 7 the support. . Although a particular embodiment of the in vention has been shown and described, it will be 50 apparent that various modi?cations and changes may be made without departing from the spirit and scope of ‘the invention. What is claimed is: » An ice freezing tray having bottom, side, and 55 2 . 2,138,266 end walls, a front plate secured to the tray in spaced parallel relation with one of said end walls, said front plate having a vertical slot and being formed to provide a handle for the tray, a lever having one end projecting through the slot in said front plate and the other end pivotally connected to’ said tray adjacent the lower front edge thereof, a spring for normally holding the 1 lever against the top of said‘ slot, and the pivoted end of said lever being formed as a cam which engages a tray supporting shelf when rotated by movement of the projecting end of said lever downward in said slot against the action of said spring to loosen any ice bond there may be be tween the shelf and the bottom of the tray.
