More detailed reference will now be made to the accompanying drawings in which I have shown several different freezing trays constructed according to my invention. Before proceeding with the detailed description, however, I desire it to be understood that the drawings are mainly illustrative and that the invention may be embodied in various other freezing trays than those herein illustrated and described.

In Figs. 1 to 4 inclusive 1 show a freezing tray for use in the freezing compartment of a refrigerator and comprising a receptacle or pan 20 adapted to contain the liquid or material to be frozen and one or more members 2| adapted to divide the interior of the pan into a plurality of matrices or cells for the formation of individual blocks of the frozen material. The pan 20 is preferably formed of metal, although it could be formed of other material if desired. 'In this instanceI show the pan as having a longitudinal partition 22 therein, which divides the interior of the pan into two elongated pockets or receptacles 23, and one of the members 2| in each of the pockets. If desired, however, the partition 22 may be omitted, in which case a single member 2[ corresponding substantially I with the width of the pan receptacle is placed therein.

The member 2|, which may also be termed a grid, is formed of a resiliently flexible or sprin y Fig. 10 is a longitudinal sectional view taken sheet material, preferably sheet'metal, and may be formed from a single strip of this material which has been bent or folded transversely at longitudinally spaced points-to provide the longitudinally spaced double-thickness vertical walls 24 and the longitudinal single-thickness bottom or connecting walls 25 extending between such double-thickness walls. As will be seen from Figs. 2 to 4, the grid thus formed has a series of similar substantially U-shaped pockets with the upright legs of adjacent pockets connected at the top thereof. The strip of sheet material from which the grid 2| is formed is of a width slightly less than the width of the receptacle 23 of the pan in which the grid is to be used.

When the grid is in position in the pan it divides the receptacle of the pan into a series of individual matrices or cells 21. The upright double-thickness walls 24 of the grid form one pair of parallel side walls of the cells and the single-thickness connecting walls 25 form the bottom walls of the cells. The other side walls of the cells are formed, respectively, by the partition 22 and an outer side wall of the pan 20.

In forming the grid 2| from the strip of springy sheet metal, the transverse folds 28 at the tops of the cell walls 24 and the transverse bends 29 at the junction of the side walls with the bottom walls 25 are preferably so formed that when the grid is in a free or released condition it will assume substantially the shape and form shown in Figs. 1 and 2. That is to say, it will assume a shape such that the cell walls 24 stand in upright substantially parallel longitudinally spaced relation in the pan and the bottom and end walls 25 and 30 lie close against the bottom and end walls 3| and 32 of the pan. By reason of the springy character or resiliency of the sheet materiai of which the grid is formed the grid can be stretched or expanded longitudinally. by means to be presently described, whereby ice blocks which have been congealed in the cells 21 can be quickly and easily loosened.

In the form of my invention shown in Figs. 1 I to '4 inclusive, I connect one end of the grid 2| 45 with an end wall 32 of the pan and provide mechanical means adapted to act on the other end of the grid for loosening the grid and ice blocks from the pan and, at the same time, expanding or stretching the grid longitudinally to loosen the ice blocks from the grid itself. The end of the grid may be connected with the end wall 32 by any suitable means, such as by crimping, soldering or brazing, or a combination of such connecting means. The connection between the grid and the end wall may also include a coninection formed by rivets 34 or the like and located subloosening action is aided by heat being trans-' mitted through th side walls from the air in the air spaces 34.

The means for loosening and expanding the grid 2| may comprise, in addition to the above mentioned connection between the gridand one end of the pan, a tensioning or winding means, 75

the pan by providing the latter with longitudinally projecting spaced arms 35 and a transverse pin 31 carried by the arms and on which the spool is pivoted. Rotation of the spool on its pivot obtained by any suitable means, such as a lever 39 connected with the spool adjacent an end thereof and extending radially with respect to the rotation axis. The spool 35 corresponds .substantially in length with the width of the grid and when two grids are employed, as shown in Fi 1, two spools of corresponding width are provided and an actuating lever 39 is provided for each spool.

From the construction of the grid and the arrangement of the grid losening or actuating means, as thus far described, it will be seen that when the lever 39 is in a position extending longitudinally of the pan, as shown in Fig. 2, the grid 2| is in its contracted or released condition engaging the bottom and end walls of the pan but when the lever is lifted from this longitudinally extending position and thereby rotated on the pivot shaft 31, the spool will be correspondingly rotated and will wind up a portion of the grid. This causes a tensioning of the grid which results in its being loosened from the pan and lifted relative thereto, and also causes the grid to be expanded longitudinally to release the ice blocks.

11' only a few of the ice blocks are needed the lever 39 ma, be rotated through only a portion of its permissible travel, whereby only the cell wall or walls nearest the spool 35 will be expanded, as shown in Fig. 3, to release the ice blocks 40 in the corresponding cells, while the remainder of the grid and the ice blocks remain substantially undisturbed. If all of the ice blocks are needed, the lever 39 may be rotated through the full extent of its permissible travel, whereupon the entire grid 2| will be lifted andexpanded, as shown in Fig, 4, and the ice blocks contained in all of the ice cells will be released.

In order to secure a substantially uniform degree of extension or expansion along the grid I may provide means for limiting the extent to which the adjacent thicknesses of the cell walls 24 may be spread apart, and particularly for the cell walls nearest the spool 35, which might otherwise be unduly distorted by the pull exerted on this end of the grid. This limiting means may be in the form of headed members or rivets 42 disposed adjacent the bottom walls 29 of the cells and extending longitudinally of the grid through the adjacent thicknesses of the upright walls 24. One or more such headed members may be provided for each of the upright walls 24 and, when the grid is tensioned by rotation of the spool 35, these members will transmit tension from cell to cell and will limit the extent to which the thicknesses of the upright walls 24 may be spread apart therebypreventing the grid from being unduly stretched or distorted.

Thus it will be seen that the improved freezing tray illustrated in Figs. 1 to 4 inclusive is of simple and economical construction, yet it provides for a quick release of some or all of the ice blocks simply by the manipulation of a conveniently arranged lever and that after the grid has been expanded to release the ice blocks the return of the lever to its initial position and the spring characteristic of the grid will automatically cause the latter to resume its proper position in the pan in readiness for another charge of the material to be frozen.

In Figs. and 6 of the drawings I show another freezing tray which is somewhat similar to the tray of Fig. l, but in which the grid or insert member is not connected with the pan. In this form of my freezing tray I show a pan 45 adapted to contain a quantity of the liquid or material to be frozen and having a strip 46 extending longitudinally of the pan for loosening and lifting the grid '41. The strip 46 is formed of resiliently flexible or springy sheet material, preferably sheet metal, and has one end thereof anchored to an end wall of the pan, as indicated at 48. The op posite end of the strip is anchored to a winding or tensioning spool 49 which is mounted on a transverse pivot pin 5|! and carried by a pair of arms or brackets 5| projecting from the other end of the pan. A lever 52 connected with the spool provides for rotation thereof in one direction to cause tensioning of the strip 46 for loosening and lifting the grid 41, and rotation in the opposite direction to permit the strip to recede into the pan. The strip 46 is preferably of a width slightly less than the width of the pan receptacle which receives the grid 41 and is so formed that when versely at longitudinally spaced points to form longitudinally spaced, upright, double-thickness walls 54 and longitudinally extending single-thickness connecting walls 55. When the lifting strip 46 is in its retracted position and the grid 41 is placed in the pan, as shown in Fig. 5, the grid rests on the strip with the double-thickness walls of the grid 54 dividing the interior of the pan into end and intermediate matrices or

cells

56 and 51. When the lever 52 is actuated to rotate the spool 49 the strip 46 is tensioned and, in assuming a more or less straight line position as shown in Fig. 6, loosens the grid 41 and lifts the same out of the pan. In this way the grid 41 is loosened from the pan and lifted to an exposed and readily accessible position so that the ice blocks can be released by a single flexing of the grid, such as may be produced by a bending or twisting thereof. The grid 41 is preferably not connected with the strip 46 so that, if desired, it can be removed therefrom to facilitate the releasing of the ice blocks after the grid has been lifted out of the pan by the strip.

In Figs. '7 and 8 I show a freezing tray of a somewhat different form but also embodying a grid or insert member which is expansible longitudinally for releasing the ice blocks. As shown in Figs. '7 and 8, this freezing tray comprises an elongated pan 66 and one or more grids 6| adapted to divide the interior of the pan into a plurality of matrices or cells 62 for the formation of individual ice blocks. I

The pan 60 may be formed with a' removable end wall 63 which is normally'held in sealing engagement with an end of the pan and with a gasket 64 by suitable means, such as therod 65 extending longitudinally of the pan. The end wall 63 may have a rod-actuating handle 66 rotatably mounted thereon and connected with v the projecting outer end of the rod as by means of a transverse pin 61. The inner end of the rod 65 has threaded engagement with a not or sleeve 69, which is anchored to the inner end wall 19 of the pan as by means of a headed part 1|, the sleeve preferably having a hinge connection with such headed part. By rotation of the handle 66 in one direction, the rod 65 can be screwed into the sleeve 69 for clamping the end wall 63 against the outer end of the pan and, by rotation of the handle in the opposite direction, the rod can be screwed out of the sleeve to move the end wall away from the outer end of the pan.

The grid 6| may be formed from a strip of resiliently flexible or springy sheet material which I is bent and folded transversely at longitudinally spaced points to form the longitudinally spaced double-thickness upright cell walls 13 and the longitudinally extending single-thickness bottom walls 14. The outer end of the grid is anchored to the removable end wall 63 by the rivets 15, or other suitable means, so that movement of such wall away from the end of the pan will cause the grid to be extended or expanded longitudinally by spreading the adjacent thicknesses of theupright walls 13. The opposite or inner 1 causes the release of theice blocks so that they can be readily dumped from the tray, or, if desired, can be removed individually in any desired number by sliding them laterally out of these cells or pockets of the grid which have been withdrawn from the pan. In Fig. 7 of the drawings I show the grid in its expanded condition and withdrawn from the pan 60 far enough to permit the ice blocks to be discharged laterally from the end cells.

Although only one of the grids 6| may be provided in the pan 60, I prefer to construct the pan vwith a longitudinally extending hollow partition 11 and to use one of the grids 6| in each of the pockets thus formed in the pan. The hollow partition 11 may be formed by a pair of laterally spaced upright walls 18 which extend longitudinally of the pan and correspond substantially in height with the depth of the pan. This hollow partition provides a convenient space in which the rod 65 and the sleeve 69 may be located. The hollow partition 11 may be provided at longitudinally spaced points with guide and bearing members 19 for guiding and rotatably supporting the rod 65.

It will thus be seen that the freezing tray 11- lustrated in Figs. 7 and 8 provides an easily operated device of simple construction from which some or all ice blocks can be readily removed as desired. It willbe seen that the screw connection for the rod 65 provides a powerful means whereby the end wall 63 can be forced away from the pan and the grid 6| thereby expanded 1onanother freezing tray of my invention comprising a pan BI and one or more insert members or grids 82 disposed therein and dividing the interior of the pan into matrices or cells 83. When two of the grids 82 are employed, as shown in this instance, the pan is provided with a longitudinal partition 84 which divides the pan receptacle into pockets for the respective grids;

The grid or grids 82 may be formed from a strip of resiliently flexible or springy sheet material which is bent and folded transversely at longitudinally spaced points to provide the spaced double-thickness walls 85 and the longitudinally extending single-thickness connecting walls 86. The double-thickness walls 85 form side walls of the cells 88 and the single-thickness walls 83 form the bottom walls of the cells. The grid 82 is so formed that when in its free or released position it assumes a contracted condition substantially as shown in Figs. 9 and 10, in which the adjacent thicknesses of the walls 85 are in faceto face contact with each other, and the 'top edges of such double-thickness walls lie substantially in a common plane which is parallel to the bottom of the pan 8|.

For loosening the grid from the pan and causing the release of the ice blocks I provide means for lifting the grid, or a portion thereof, relative to the pan, and which can also be operated to flex or expand thegrid to loosen the ice blocks therefrom. This means may comprise a substantially rigid bar 88 extending longitudinally of the pan through the aligned slots 89 formed.

in the walls 85 adjacent the tops thereof. The

grid 82 is preferably made somewhat deeper than 1 the pan 8I so that the slotted tops of the walls 85 will project above the top of the pan and the bar 88 may extend across the end walls 90 and SI of the pan.

In using the bar .88 as a grid loosening and panding means, it is actuated as a lever of the second class and during this actuation a lifting force is applied to its curved outer end 92 while its inner end fulcrums either on the inner end wall of the pan when the entire grid is to be lifted or on one of the upright walls 85 when only a portion of the grid is to be lifted. A suitable fulcrum and retaining means for the inner end of thelever may be provided in the form of an upright ear 83 secured to the inner end of the pan and projecting thereabove and provided with a slot 94 through which the inner end of the lever extends.

When the operator wishes to loosen the entire grid 82 by a single operation, such as when all of the ice blocks are needed and it is desirable to remove the grid from the pan for discharging the blocks at one time, the curved outer end of the bar 88 is lifted while its inner end fulcrums on or adjacent the inner end of the pan. In this way the entire grid can be lifted relative to the pan to the dotted line position 95 shown in Fig. '11. During this lifting operation the grid and the ice blocks are broken away from the walls of the pan and, at the same time, more or less flexing may occur in the grid itself to cause the ice blocks to be broken away from the side and

bottom walls

85 and 86. .After loosening the grid from the pan by the lifting or prying action of the bar 88, as just explained, the ice blocks can be pushed ordum-ped laterally out of the cells, or, if desired, the bar may be withdrawn from the slots 89 and the grid flexedor twisted to further loosen the ice blocks.

If only afew of the ice blocks are needed or if the grid and blocks are frozen in the pan too tightly to be lifted in one operation, as explained above, the operator may withdraw the bar 88 part-way from the grid 82 to bring the inner end thereof to a fulcrum position on a certain one of the upright walls 85, whereupon the bar is lifted or swung upwardly to lift and expand the corresponding outer end portion of the grid from.

which the ice blocks are to be released. The dotted line position 96 of Fig. 11 shows the bar 88 partially withdrawn and actuated in the manner I end of the tray as by the pair of ears IOI or other suitable means. The handle I00 provides a pulling 'means for grasping the tray and withdrawing the same from the freezing compartment I02 (see Fig. 12) and also, serves as a lever for lifting the outer end ofthe tray and thereby breaking the same away from the bottom wall I03 of the freezing compartment. For the accomplishment of the latter purpose I provide the handle I00 with a cam or lever portion I04 which is eccentric to the pivot I05 and which bears or cams against the wall I03 of the freezingcompartment when the handle is swung relative to the pan as by means of a pulling force applied thereto. The handle is preferably formed with a curved top portion I08 which is adapted to overlie the curved outer end portion 92 of the grid lifting and expanding bar 88 when the handie is in its normal position, as shown in Fig. 10.

In Figs. 13 and 14 I have shown still another freezing tray of my invention comprising a pan H0 and one or more insert members or grids I II therein which divide the interior of the pan into a, plurality of matrices or cells II2. When two'of the grids III are to be employed the pan may be provided with a longitudinally extending partition II3 dividing the interior of the pan into pockets in which the grids may be disposed. The grid III maybe similar to the grid 41, shown in Figs. 5 and 6, that is to say, it may be formed from resiliently flexible or springy sheet material which is bent and folded transversely at longitudinally spaced points to provide the upright double-thickness walls I I4 and the longitudinally extending single-thickness connecting walls II5. In its' normal or free condition the grid assumes a contracted form corresponding substantially with the full line position shown in Fig. 14 but, when lifted relative to the pan H0, is adapted to be flexed or bent to the armate condition represented by the dotted line position I I8 in which condition the adjacent'thicknesses of the walls III have been spread apart to expand the grid longitudinally and thereby loosen the ice blocks. For lifting the grid III relative to the pan IIO I provide a. resiliently flexible lifting strip III which extends longitudinally of the pan and has opposite ends H8 and H8 thereof connected respectively with levers I 20 and I 2|. The strip II! is such that when in its free or released condition it will assume substantially the form and position shown in full lines in Fig. 14, that is to say, will lie close to the wall of the pan H0 and grid will be lifted out of the pan and will be more or less bowed and expanded, as indicated by the dotted line position H6, depending upon the extent which the end or ends of the strip may be lifted relative to the pan.

The levers I20 and I2I may be formed from metal bars bent to substantially U-shape, as shown in Fig. 13, so that intermediate sections of the bars form the handle portions I22 and I23 and end portions of the bars form the pairs of lever arms I24 and I25. The arms I24 and I25 are connected with the sides of the pan by means of pivots I26 located substantially on the vertical transverse mid-plane and are provided respectively with slots I21 and I28 of substantial length through which these pivots extend and which permit longitudinal movement of the levers relative to each other and relative to the pan. Adjacent the handle portions I22 and I23 the levers are provided with transversely extending anchor rods I29 and I30 to which the ends H8 and H9 of the strip II! are fastened. The rods I29 and I30 extend through the slots I21 and I28 of the levers so that the rods may have relative shifting longitudinally of the slots.

When the grid 'III and the lifting strip- III occupy their normal positions, as shown in Fig. 14, the levers I and I2I lie in substantial alignment with each other and extend longitudinally of the pan just below the top edges thereof. Pairs of laterally projecting clips I3I. and I32 engageable with the top edge of the pan may be provided for assisting in holding the levers in this position. When the grid is to be lifted and expanded for releasing the ice blocks, one

' or both of the levers I20 and I2I are lifted relative to the pan. The lifting of these levers causes the corresponding end or ends of the strip III and of the grid III to be lifted and at the same time flexed to the bowed condition represented in the broken line position II6.

In Figs. 15 and 16 I show another freezing tray of my invention comprising apan I33 and an insert member or grid I34 therein. The grid is similar to the grid III of Fig. 14 and the grid 41 of Fig. 6, that is to say, it may be formed from a strip of resiliently flexible or springy sheet material which is bent and folded transversely at longitudinally spaced points to provide the double-thickness upright walls I35 and the longitudinal single-thickness connecting walls I30. When the grid is disposed in the pan, as shown inFig. 16, the walls I35 divide the space into a plurality of matrices or cells I31 having the single-thickness walls. I36 as their bottom walls. The grid is so formed from the springy sheet material that when it is in its free or released condition it assumes substantially the shape and form shown in Fig. 16 and is adapted to rest upon and closely engage the bottom of the pan I33.

The strip of sheet material from which the grid I34 is formed may be slightly narrower than the interior width of the pan when a single grid is employed, or if two grids are desired, the pan may be provided with a longitudinal partition wall I38 to divide the interior thereof into two pockets in which the respective grids are received.

For lifting the grid relative to the pan I33 to thereby free the grid and the ice blocks coninclude a substantially U-shaped lever I40 having a transverse handle portion I4I disposed adjacent one end of the pan and a pair of substantially parallel arms I42 expanding longitudinally of the pan outside thereof and having their inner ends connected with the pan so as to permit both longitudinal and pivotal movement of the lever relative to the pan. To permit this relative movement the arms I42 may be provided with slots I44 adjacent their inner ends through which rivets or pivot pins I45 carried 'by the side walls of the pan extend. For transmitting motion from the lever I40 to the transverse lifting bar I39, I provide links I46 which connect the arms I42 of the lever with the ends of the transverse lifting bar. The links I40 have pivotal connection with the ends of thetransverse bar I39 and also have pivotal connection with the lever arms I42 at an intermediate point thereof.

With the grid lifting arrangement just described it will be seen that when a person grasps the handle portion I4I of the lever I40 and pulls forward on the same to cause relative longitudinal movement between the lever arms I42 and the pan, it will cause swinging of the links I46 from a relatively inclined position to a substantially vertical position. This swinging of the links will cause a powerful thrust force to be applied to the ends of the transverse bar I39 tending to lift the grid relative to the pan. This initial thrust force acting on the grid breaks the same and the ice blocks away from the walls of the pan so that, by subsequently swinging the lever I40 upwardly to its broken-line position I41 or higher, it will lift the grid and the ice blocks to the corresponding elevated brokenline position, shown in Fig. 16, or entirely clear of the pan, if desired. When the grid and ice blocks have been lifted out of the pan by the operation of the lever I40, as just explained, he grid can be grasped and flexed or twisted slightly to further release the individual ice blocks.

When the grid I34 occupies its normal position in the pan I33, as shown in Fig. 16, the lever I40 extends longitudinally of the pan with the lower edge of the lever substantially flush with the bottom face of the pan. Hence, when the pan is inserted into the. freezing compartment of the refrigerator, the lever I40 will engage the face or bottom of the freezing compartment upon which the bottom of the pan rests. When the pan is to be removed from the freezing compartment the lever I40 can be drawn forward to cause the initial lifting force to be applied to the grid I34, as explained above, and then can be pressed downwardly against the bottom of the freezing compartment and thus used as a. lever for loosening the pan. This downward move ment of the lever I40 for loosening the pan from the freezing compartment is illustrated in Fig.

When the pan I33 contains two of the grids I 34 and is provided with the longitudinal partition I38, the transverse grid lifting bar I39 is preferably formed with a doubled intermediate portion lBi which extends over the top of the partition, as shown in Fig. 17.

From the foregoing description and accompanying drawings it will now be readily understood that I have provided an improved freezing tray for refrigerators which is so constructed that the ice blocks formed in the cells of the tray can be quickly and easily removed therefrom. It will also be seen that the facility with which the ice blocks can be removed from my improved freezing tray results, in part, from the use of a novel form of rwiliently flexible and expansible grid and, in part, from the useof a conveniently operable manual means for loosening the grid and ice blocks from the pan. Additionally, it will be seen that I have provided simple and convenient means for loosening the pan from the freezing compartment when the tray is to be removed therefrom.

While I have illustrated and described my improved freezing tray in a somewhat detailed manner it will be understood, of course, that I do not wishto be limited to the particular embodiments and details of construction herein disclosed but regard my invention as including such changes and modifications as do not constitute a departure from the spirit of the invention and the scope of the appended claims.
