ICE TRAY Y Application 1111511 April as, 1981. Serial 1T0. 533,769.

This invention relates to ice trays especially adapted for refrigerators and has for the primary object, the provision of a device of the above stated character whereby the blocks .of ice formed therein may be more conveniently. removed than in the present types oftrays, due .to the construction of the tray which will cause an easy displacement of any one of the blocks of ice when pressure is ap- '1 plied near one edge thereof, positioning the of the blocks of ice, the block 0 ice slide upwardly in the arc of a circle presentin the opposite edge of the block outwardly o the m compartment to permit it to be easily grasped for tr'emotal from the respective compart-, .men

- A further object of this invention is the provision of an ice tray of the above stated zscharacter which will be simple, durable and l efiicient and which may be manufactured and sold at'a comparatively. low cost. With these and other bjects'in view, this invention consists in certain novel. features aoof construction, combination and arrangement of parts to be hereinafter more fully described and claimed. f y

Referring in detail to the drawing, the numeral 1 indicates, in its entirety, a tray to be employed in the freezing unit of a refrigerator for forming blocks of ice or other ingredients into frozen forms. The tray 1 includes a semi-cylindrical shaped wall 2 having formed integral therewith a plurality of relatively spaced semi-circular shaped partiso tions 3 providing a plurality of compartni'ents adapted to contain water or other ingredients to be frozen. The curved edges of the. partitions are formedintegral with the semi-cylindrical wall 2 with the straight edges 05 p i of the partitions disposed flush with the edges of the semi-cylindrical wall 2, so that the blocks of ice or other ingredients frozen within said compartments will be ofsemi-circular. shape as shown in Figure 1 having their straight edges disposed uppermost while lying within the tray. The side edges of thesemi-cylindrical wall 2 are formed integral with com aratively narrow flanges 4 on whichare ormed side plates 5 roviding runners to, engage the usual gui es within the freezing unit of a refrigerator for efficiently supporting the tray therein and permitting the easy removal and application of the tray to the freezing unit when desired. The 80, plates 5 at one of their ends are slightly curved as shown at 6 to facilitate the appli- I cation of the tray onto the usual supporting guides in the freezing unit. A front wall is formed integral with the other ends of the plates 5 and also forms a side wall to the end compartment of the tray and has secured thereto a suitable handle 8 for aiding in applying and removing the tray from the freeztents of the compartments have been frozen into semi-circular shaped blocks and the tray removed from the freezing unit of the refrigerator water is allowed to flow thereover for a short period of time which loosens the blocks 95 from the walls of the com artments and to remove any one of the bloc s, pressure is applied to the respective block adjacent one edge and due to the semi-cylindrical wall 2, the block will be caused to slide in the arc of a- After the concircle presenting the opposite edge of the block outwardly of the respective compartment, so that it may be easily grasped and removed as shown in Figure 1. Referring-to Figure 5 which illustrates one modified form of my invention, the tray 9 is similar in construction to the tray 1-' except the partitions each include relatively spaced walls 10 joined at their upper edges by comparatively short top walls 11 providing spaces 12 within each partition to provide a greater freezing area for the tray, or in other words, the cold temperature may enter the spaces 12 thereby freezing the contents of the compartments in a much shorter period of'time,

Referring to Figures 6 and 7 which illustrate another modified form of my invention, the tray 13 consists of a substantially rectangular shaped plate 14 having one end reduced and flanged as shown at 15 to which a handle 16 is secured. A plurality of semierator. It being understood that the side spherical shaped depressions or pockets 17 areformed by pressing the material of the plate 14 outwardly in which the water or other ingredients may be placed for freezing within the usual freezing unit of the refrigedges of the plate l t-engage the usual supporting guides within the freezing unit. The

pockets or depressions 17 form individual compartments and each-having a curved wall so that when the frozen block is pressed upon adjacent one edge, the block will'slide in the arc of a circle presenting the opposite edge of the block outwardly of the pocket or depression that the block maybe easily grasped v and removed.

semi-circular shaped'partitions formed in- I y te ally with the inner faces of the semi 1 cy ,ndrical shaped walland one of the end partitions'forming aclosure for the other end of the semi-cylindrical shaped wall, said partitions, wall and plate cooperating to provide semi-circular shaped compartments to -con-' tain frozen blocks whereby pressure applied invention, as claimed;

Aii'ice tra comprising. a plate havingone end reduce and bent angularly to form an attaching flange, a handle secured to the flange for sliding said plate into and out of a freezing unit, said plate having spaced portions offset outward y therefrom to form semiherical shaped pockets with curved walls ibr containing frozen blocks whereby pressure applied to any one of the blocks adjacent one edge will cause sliding of said block to position the. opposite edge thereof outwardly of the respective pocket so that it I may be readily grasped.

In testimony whereof I afiix mysignature.
