ICE GRID Filed Feb. 4, 1929 Patented Nov. 11, 1 930 EDWIN P. S. NEWMAN, OF'WASHINGTON, DISTRICT OF COLUMBIA ICE GRID Application and February 4, 1929. Serial n. 337,424.

1 The present invention is an improved grid for the drawers or trays of ice making machines in which trays ice cubes for domestic use are formed. These'grids divide the trays into a plurality of compartments or spaces in which water is placed sothat'after the refrigerating operation a plurality of ice cubes are, provided. 4

The grids generally in use are. removable of the tray to be released. The result of this being that often many or 'all of the cubes of ice drop from the tray becoming dirty or unusuable and the hands become'chilled or wet during the operation. I

The object of the present invention is to provide an improved grid forcube making trays overcoming the drawbacks renumerated above, and wherein it is not necessary to invert the tray to" secure removal of the ice cubes; where the grid may be removed from the tray without the hands touching the ice cubes or the grid per se; where the rid containing the cubes may be removed rom the tray and the cubes individually removed therefrom as desired.

Theinvention further has for its object the provision of a grid of the above stated chartrate several examples of an ice tray grid embodying the principles of the invention,

as at present devised:

Figure 3 is a perspective View of a grid of modlfieddesign and constructed in accord ance with the present invention;

Figure 4 is a fragmentary sectional view of another modified construction embdyi-ng the invention;

Figure 5 is a plan view of Figure 4; Figure 6 is a fragmentary sectional view taken substantially on line 66 of Figure 4:; and v Figure 7 is a plan view of a modified grid. To accomplish the objects above enumerated, the removable gridfor ice trays of refrigerating apparatus is provided with a plurality of vertical partitions 10, of suitable material, connected together in any suitable manner or design forming a unitary frame removable from the ice tray 11. The grid thus forms, when in the tray, a multiplicity of compartments 12 each producing an ice cube in a manner well understood in the art during the refrigerating operation, the grid per se being opened on its top and bottom sides.

' These compartments 12 are such as are capable of preventing the ice cubes from falling or dropping therefrom, when the grid has been. removed from the tray as shown in Figure 1, yet being opened at their bottom to permit the insertion of the grid in a tray of water in. the usual manner previous to refrigeration and, further, for per 'mitting a finger or other implement to be inserted in the bottom of the compartment to assist in removing the individual ice cube from each compartment. The grid of course is preferably provided with a suitable handle 13 by which the grid containing all of the ice cubes can be removed from the tray after the ice therein has sufliciently thawed to release itself from the walls of the tray. Several examples are shown in the drawings for construcwting the compartments to accomplish this pu pose, although applidesired purpose.

' compartments.

. I In Figure These flanges are shown as continuous, but.

may only be smaller projections 1 1* in contra-dlstinction to continuous, and moreover may not be provlded on all walls of a compartment but only on one or possibly two of the walls as is necessary to accomplish the (See Figure 7.)

In order to prevent accidental lateral movement of the cubes from the outer compartments of the grid, which are only provided with three side walls, the outer ends of each partition or wall is provided with a like flange or projection 15 at its lower corner, substantially the outer edge of- Figures 1 and 2. these projections or flanges 15 may be formed by a continuation of the flange 14.

The handle'13 may be of any suitable de sign or construction, but is here shown as of a bail type having its free ends inturned and received in suitable openings 16 formed in the partitions of the grid. As shown in Figure 1, the handle 13 is positioned centrally of the grid so that the same will be selfbalancing and is connected with the outermost partitions so as not to interfere with the removal of the ice from the adjacent upwardly for a distance with the partition, as shown in slightly bent in order that the handle portion 13 thereof will lie downwardly against a side edge of the tray 11, is in its lowered position, and thereby not interfere with the insertions of the tray or drawer into the drawer opening of the refrigerator.

3 a modified form of grid is consists of a central partition 17 having spaced and laterally extending vertical partitions 18 extended therefrom. This form of grid permits the formation of an elongated ice cube, and, further eliminates the rovision of central compartment-s closed by our side walls from which the removal of the ice is. not as convenient as when-the shown which cube compartments have only three walls removed, thus enabling the ice cubes to be removed by the thumb and forefinger as shown in Figure 1'. I v

Figures 4, 5 and 6 show a further modified form of grid, where the ice is prevented from dropping from the compartments of the grid by the vertical partitions 10 thereof having which flange or projection 15 extends As shown in the drawings v The side legs of the bail are when the handle a very sanitary, novel and nsefnllce tray grid has been provided for overcoming many of the ob ections and drawbacks attendant with the grids now commonly in use. The ice cubes formed in the present grid need not be touched by human hand in order to effect their removal, but may be passed around in the grid which acts as a-supporting or serving tray. The present invention also eliminates the now very disagreeable and unpleasant experiences in removing ice cubes from the tray by inverting the tray and holding same under water resulting in the loss of many cubes falling into a sink or other receptacle during the melting operation necessary to remove the cubes from the tray as is now commonly in practice. but on the contrary permits only those cubes that are desired to be conveniently removed, after the grid has been raised from the tray.
