and some flexible non-metallic partition walls J whereby to obtain faster freezing than is obtainable with a grid having all partition walls of flexible rubber or other non-metallic material.

Another object is to provide a freezing grid having a series of separate inetal partition walls loosely joined together to form a relatively long non-rigid metal partition wall which may be easily distorted to facilitate the removal of the frozen ice blocks.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawings wherein a preferred embodi- 25 ment of the present invention is clearly shown.

In the drawings: Fig. 1 is a plan view of an ice tray and removable grid therein made according to this inven- Fig. 2 is a section on line 2-2 of Fig. 1. Fig. 3 is a section on line H of Fig. 1. w ti Fig. 4 is a detail view of one of the cross partions.

Fig. 5 is a section on line 5-5 of Fig. 4. Figs. 6 and 7 are side view and cross section respectively of one end element of themetal partition.

Figs. 8 and 9 are side view and cross section respectively of one intermediate element of the ,40 metal partition.

. on closed in applicants copending application Serial No. 88,559, filed July 2, 1936.

The removable grid comprises a, series of separate metal sections II, II, and il loosely attached together to form-the central longitudinal parti- 55 tion walldesi/gnated asa whole by numeral ii.

The end metal section II is preferably flatwith a vertical slot I! at one edge thereof as shown in Figs. 6 and 7. The other end metal section l3 has anoflfset edge portion it having a vertical slot i1 therein (see Figs. 10 and 11). The inter- 5 mediate "metal sections I! each has a similar oilset edge portion l8 with a vertical slot I'I therein T and also a vertical slot I! at the other vertical edge thereof. All the intermediate sections i2 may be made identical in form as shown in Figs. 8 and 9, and every alternate section i2 may be simply reversed top for bottom to obtain the arrangement shown in Fig. ,1; When the metal sections l I, I2. and I3 are all arranged in slightly overlapping relation as shown in Fig. 1,-the verti- 15 cal slots I! will register at each overlap.

The flexiblenon-ametallic cross partitions are shaped as shown in Figs. 4 and 5 and are preferably cut to shape from a flat sheet of flexible rubher or other suitable flexible non-metallic mate- 20 rial which may be easily peeled from the frozen ice blocks bonded thereto. These flexible cross partition's 20 are slotted out at slots 22 to provide a central neck portion 2| of such dimensions as will fit, snugly within the registered slots i1 25 in the overlapping metal. sections and thereby yleldably hold. said metal sections together.

The parts are assembled'together in a verysimple. and eflicient manner as follows. The

wide portions of the cross members 20 are suf- 80 flciently flexible and stretchable as to be threaded thru thealigned slots il in two overlapping metal sections simply 'by inserting a corner of member 20 thru the slot l1 and then pulling half of the flexible member 20 thru said slot until the neck portion Zisnaps into place and substantially fllls the slot II. The edges of slots 22 form yielding shoulders which abut snugly against the lateral surfaces of the overlapping metal sections and so retain these overlapping portions in 40 1 mutual'lateral contact.

In operation, the removable grid is set down into the pan ili either before or after pan i0 is filled with water'to the desired level; The pan is thenset within a freezing compartment until the ice is solidly frozen. To remove the ice blocks from the tray, the grid and ice contents are first removed from the pan as a unit by any suitable or p esently known method. The grid may then be r dily flexed by hand by bending or twisting same from. end to end or by anyother suitable distortion thereof to cause the ice blocks to loosen therefrom. Since the central metal partition wall is'composed of metal sections yieldably joined together so as tobe relatively movable members and 'a plurality of flexible rubber par titioning members, said metal members being yieldably held together by said rubber members.

2. A freezing tr'ay having a removable grid, said grid comprising a series of separate metal partition walls arranged in substantial alignment to form a composite partition wall, and a series of flexible rubber partition walls, said metal partition walls being yieldably held together by said rubber partition walls.

3. A freezing tray having a removable grid, said grid comprising a series of separate metal partition walls having slightly overlapping por-" tions, and a series of flexible rubber partition walls intersecting said overlapping portions and yieldably holding said overlapping portions together. .4

4. A freezing tray having a removablegrid, said grid comprising a series of separate metal partition walls loosely joined together to form a relatively long non-rigid partition wall, and a series of flexible rubber partition walls, said separate metal walls being loosely joined together by said rubber walls.

5. A freezing tray having a removable grid, said grid comprising a main longitudinally expansible metal partition wall having longitudinally expansible joints therein and a series of separate flexible rubber partition wallsextending transversely across said metal wall and secured thereto. I l r 6- A freezing tray having a removable grid, said grid comprising a series of separate metal partition walls having slightly overlapping slotted portions having substantially aligned slots therein, and a series of flexible rubber partition walls intersecting said overlapping portions and having flexible'rubber portions extending through said aligned slots in said metal walls.

'7. A freezing tray having a removable grid, said grid comprising: a main longitudinal metal partition wall having expansible joints therein which v facilitate bending of said main wall in its longitudinal plane, and a series of flexible rubber cross partition walls extending transverse to said main wall and carried thereby.

8. A freezing tray having a removable grid, said grid comprising: a main longitudinal metal rpartition wall having expansible joints therein which facilitate bending of said main wall in-its longitudinal plane, and a series of readily dis-- tortable rubber cross partition walls extending across said main wall and forming therewith two rows of ice block compartments, said cross walls being distortable by the bending of said main wall in its longitudinal plane, to facilitate the removal of the frozen ice blocks'therefrom.
