INVENTOR,

Morris H F osier- ATTORNEYS Patented Apr. 7, 1953 UNITED 1 STATES PATENT l.()FFICIEZ HOME' REFRIGERATION UNrrl losv TRAY Morris H. Foster, South Charlestonl W. Vai. Application April 26, 1950,., SeralNo. 158,206,

l This invention relates to ice trays, and more particularly to an ice4 ktray having removable and separable parts, whereby theice cubes may be'removed as a- Whole from the tray proper, or whereby the icewithin individual compartments may be crushed.

h1- the past considerable di-iicultyhas been experienced in removing the ice 'cubes as a whole from the tray, or removing individual cubes of ice or crushed ice from the tray without removing the entire assembly from vthe tray.` I have found that thesediiiiculties can be eliminated by the novel constructionV hereinafter described. This structure includesmeans for removing the-- 'entire assembly of ice cubes from the tra-y.

Additionally, should itbe desired to obtain ice, suchV as individual ice cubes, crcrushe'd ice'cu'bes, without removing the entire assembly, such smaller portions of ice l may be obtainedA readily Without removing the assembly from the tray.

object of theinvention, therefore, is to pro- Y vide an ice tray having La plurality of transverse- I y extended partition plates or separator members which a-re mounted on a spacer strip, .which assembly may be removed as a Whole' from theA imy- A further object of the invention is to provide a structure in accordance with the foregoingr paragraph in which the transverse partition plates or separatormembers are composed of fiexible material.

Another object is to provide an ice tray structure having special mountingv means for the transverse partition plates or separator members whereby individual plates may be pivoted.

A further obiect is to. provide an ice tray struc- 'tureY having transverse partition vplates, or separatcrymembersand an additionalI transverseA plate having a lever type handle fastenedl thereto, yor forming a part thereof. whereby operation of 'the handle will free a' cube of ice at one end of the tray to permit pivotal movement of the aforementioned plates or separator members.

Yet another object is toI provide an ice tray having transverse partition plates or separator members with means for suppporting said members that includes a tension member for holding said plates or separator members' in place.

Other objects of the invention will be disclosed throughout the specifications. Y u

In the drawings herein, similar reference characters refer to similar parts in the speciiication:

Fig. 1 is a transverse vertical section view of the ice tray with thefparts in assembled position fol freezing ice cubes, l

Fig. 21s a front elevation 'of one of the transverse partition plates or separator members.

Fig. 3 is an end viewjoi oneform of rectangular-shaped metal spacer strip,

Fig. 4 is an end view of another form of spacer strip, and

Fig. 5 is a top plan viewv of the ice tray.

Before explaining lin detail the present invention, it is to b e understood that the invention is not limited in its application tor details ofv construction and arrangement of parts illustrated in the accompanying drawings and set forth in the following descriptiom since the invention is capable of other embodiment. It is to be further understood that thedisclosure as shown in the drawings and' hereinafter described, is for the purpose of `description and not of limitation, and it is not intended to'limit the invention classed herein beyondthe requirements of the prior.

Referring to the drawings: I

The letter A indicates the tray per se; the letter B indicates the cube assembly as a whole, and the letter C indicates the lever and plate assembly.

The tray is provided with ends Il! and l2. Extending longitudinally of the trays and substantially centrally thereof is a rectangular-shaped metal spacer strip Ill.' This strip is provided with a series of` transversely extending notches I6.

A plurality of transverse partition plates or separator members I8 are provided. Each of these separator members has a lower, centered notch 20, of such size that the spacer strip may extend through the notches when the plate members. are inthe inclined position shown in Fig. l. For. holding each, separator member of the spacer strip there. is'provided a spring 22, having upturned ends 24 and 26. Each spring 22 is made of. wire that has been bent into the U-shape shown in Fig..2, and in this position the ends 2li and 2li of the' spring are under tension and are therefore biased to a straight position. The strength of the tension of each spring 22 is only enough to secure the separator member or plate I8 towhich it is attached in a xed position relative to the spacer strip and not sufficient to straighten the separator member. In other words, the tensioning means does not position the separator members in a vertical plane butv permits them normally to take the position as shown in Figure 1. The central portion of each spring engages in some one oi the transverse notches I6.. and each spring is held to its plate by a plurality of pairs of holdingmembers 28, which may be fingers that have been struck from the partition plates or that may be U-shaped members which have been welded to the plates I8. It is to be understood that instead of providing pairs of such members, only one such holding member need be provided on either side of the notch 20.

It will be noted that due to the construction heretofore described each plate I8 is freely pivoted about a pivot which is defined by the notch I6.

The end plate 30 is provided with an offset portion 32, as seen in Fig. 1.

Instead of providing a solid-rectangular metal spacer strip such as is shown in Fig. 3, a spacer strip such as shown in Fig. 4 may be provided. This may consist of a longitudinally extending member of the same outside shape on three sides as the spacer strip I4. In other words this strip 84 may be of sheet metal which is channel-shaped in cross-section. The strip is provided with a pair of notches 36, corresponding to the notch I E.

The member C consists of a heavy gauge plate or handle 33, with an upwardly inclined end 4B. The opposite end of this handle is preferably integral with an additional plate 42, which is of the same general shape as the plates I8, but which omits the thumb tabs of said plates I8, now to be described.

Each plate I8 is provided with a thumb tab 4B,

and the plates are so arranged that when viewing the tray from either end thereof alternate thumb tabs will be adjacent to opposite sides of the tray. In other words, the plates are so mounted on the spacer strip that the thumb tabs of consecutive plates are adjacent opposite sides of the tray. This arrangement provides additional space between the plates for the insertion of a finger of the user to flex the plate by engaging the thumb tab 46. It will be understood that the plates I8 are made of flexible metal so that they may be not only pivoted about the notch I6 or 36, but they may be also flexed so as to break the ice within the space beween adjacent plates. y With the parts assembled in the position shown in Fig. 1 the tray may be lled with Water up to slightly below the top of the tray. In this position the thumb tabs project upwardly above the water on adjacent opposite sides of the tray. The tray is inserted in the freezing compartment of a refrigerator or deep freeze unit.

After the freezing of the Water in the tray takes place, some or all of the ice within the tray may be removed.

In the event it is desired to remove all of the ice from the tray, the inclined end 40 of the handle 33 is engaged by the fingers and pulled upwardly. This opera-tion accomplishes two purposes, viz., it pulls the ice which has frozen in the space between the lever plate 42 and the inclined end I2, and it also breaks loose the cube assembly B from the tray A. Ice may be removed from between individual plates by engaging a tab 46, and moving it so as to crush the ice on either end or both sides of the plate. Only the ice itself opposes movement of the plate about the pivot dened by the notch I 8.

The lever and plate assembly C is entirely independent of the assembly B, the lever 38 finding its support, as shown in Fig. 1, on the edges 48 of the plates.

Assuming that the ice has been frozen in the tray with the parts as shown in position at Fig. 1, and it is only desired to remove ice from between one or more of the plates I8, this is accomplished by gripping the inclined end of the handle 38, and

,4 moving the same upwardly so as to break the ice between the lever plate assembly 42 and the inclined end I 2 of the tray. Without removing the cube assembly B in the tray, ice may be removed from between any pair of plates by pivoting one or both of the plates. This is accomplished by grasping the tabs 46 of said plates and moving the plates about the pivot dened by the notch I6 or 36, according to which spacer strip is used.

Such movement of the plates will crush the ice into small pieces, when the plates are pivoted in this manner.

It is to be understood that any shape of tray or plate I8, 30, and 42 may be used to accomplish the purpose intended. It is also Within the scope of the present invention to use any desired number of such plates so as to divide the icetray into any desired number of, and shapes of, separate compartments as defined by said plates.

I claim:

l. A grid for an ice tray comprising spacer means, a plurality of spaced plates, and means pivotally mounting said plates on said spacer means, said means for pivotally mounting said plates on said spacer means including a series of notches in said spacer means, and spring means mounted on each plate for engagement with one of said notches, said spring means being under tension whereby said spring means is continually urged upwardly in said notches.
