5 Claims. (Cl. 62-106) This invention relates to refrigeration and particularly to an arrangement for ejecting ice blocks from a freezing device into a storage bin.
There has recently been placed on the market an arrangement whereby ice blocks are ejected from a freezing device including a tray that is twisted by pushing the device along stationary supporting tracks in a freezing compartment of a refrigerator which tracks are inclined or curved relative to one another. While the public has favorably accepted this arrangement, there are some users of refrigerators having the same incorporated therein who have expressed objections thereto. One of these objections is that of the great force required to be applied to the freezing device to push it along the tracks to cause twisting of the tray thereof and ejection of the ice blocks therefrom. Another objection to this now well known ice block ejecting arrangement is that of the ice block ejector being permanently located in the refrigerator thereby eliminating use thereof at a kitchen work ledge where the housewife may be mixing and chilling drinks or the like prior to serving. I contemplate an arrangement for harvesting separated ice blocks from a freezing device without twisting the tray of the device and which harvesting operation can be carried out in or away from a refrigerator cabinet with a minimum of effort on the part of the user of the refrigerator to thereby overcome the aforesaid objections.
An object of my invention is to provide an improved low cos. arrangement for releasing or ejecting ice blocks from a freezing device associated with a household refrigerator cabinet.
Another object of my invention is to provide a unitary freezing device including a tray and a movable walled grid locked in the tray against detachment therefrom wherein the grid walls are moved relative to one another and to the tray without twisting the tray with a force multiplying leverage mechanism located on the device for ejecting ice blocks therefrom while the device is supported in an inverted position on a support therefor.
Still another object of my invention is to provide a combined freezing device support and ice block storage receptacle element for the reception of a freezing device from which ice blocks are to be released and collected in the receptacle of a type that can be used either in a refrigerator cabinet or at points remote therefrom.
A further object of my invention is to provide a unitary freezing device including a grid locked in a tray against removal therefrom, the walls of which grid are tiltable relative to one another and to the tray while the device is held stationary in an inverted position on a combined support and ice block storage receptacle without distorting the tray by a manually actuated leverage mechanism on the unitary freezing device.
A more specific object of my invention is to provide a portable combined freezing device receiving and ice block storage receptacle element with means which prevents movement of the tray of a fi'eezing device supported thereon while ice blocks are being released from the device and wherein a portion of which means serves as a handle for the combined element in transporting same to or away from a refrigerator cabinet.
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 form of the present invention is clearly shown.

Figure 6 is a view similar to Figure 5 showing the leverage mechanism on the freezing device moved with walls of the grid of the device shifted relative to one another and ice blocks ejected from the freezing device into the storage receptacle.
Referring to the drawings I show in Figure 1 thereof a refrigerating apparatus including an insulated household refrigerator cabinet 10 of the multiple compartment type in which the present invention is particularly useful. Cabinet 10 is provided with a lower unfrozen food storage compartment, or chamber 11 which is cooled to a temperature of from 37 F. to 43 F. by a plate-like sheet metal evaporator 12 of a refrigerating system associated with the cabinet and mounted behind a protecting cover or baflle 13. Cabinet 10 is also provided with an upper freezing or frozen food storage compartment or chamber 14 which is cooled to a temperature well below 32 F. for the storage of frozen foods, for freezing foods and/ or for freezing water into ice blocks for table use in chilling drinks in glasses. Chamber 14 is refrigerated by an evaporator of the refrigerating system associated with cabinet 1t), which evaporator is in the form of a conduit coiled or wrapped around the outside of and secured to a metal can-like member 15 forming the liner of chamber 14 as indicated by the dotted lines 16 in Figure 1. An insulated door structure 17, hingedly mounted on cabinet 10 for horizontal swinging movement relative thereto, extends across the front of both compartments or chambers 11 and 14 and is provided with a gasket 18 for sealingly engaging the front side of cabinet 10. Another smaller door, shown broken away in Figure 1, separate from door 17 may be hingedly mounted at the front of chamber 14 for vertical swinging movement to provide an individual closure for its access opening as is conventional in the art. A plurality of metal shelves 19 are secured, in any suitable or desirable manner, directly to a side wall of liner 16 so as to be in intimate metal to metal contact therewith and consequently with evaporator 16. Each shelf 19 is adapted to support an elongated unitary freezing device, generally represented by the reference numeral 20 in Figure 1, and shown more in detail in other figures of the drawings.
Each of the unitary freezing devices 29 includes a at theback of the device.
stamped sheet metal pan or tray 21 provided with a bottom and outwardly inclined sides 22 and ends 23 (see Figures 2 and 3). The rear end 23 of tray 21 is provided with an opening 24 adjacent the top rim thereof and the other or front end of tray 21 is notched out as at 26 (see Figure 2) and this notch extends downwardly through the top rim to a short distance therebelow for a purpose to be presently described. Two opposed clamping brackets 27 are welded to the notched end of tray 21 one'on each side of notch 26. A movable walled grid structure is locked in tray 21, against removal therefrom and includes a two-part metal longitudinal partition and a; plurality of spaced apart metal walls extending transversely of the longitudinal partition rfor dividing the interior of tray 21 into a plurality of rows of compartments in which water is to be frozen into separate ice blocks. The longitudinal partition of the grid structure comprises a lower wall 31 and an Upper actuatlower wall 31 of the long partition and to tray 21. The
. other'or' forward end of lower wall 31 of the longitudinal partition is-provided with an ear- 44- fitting innotch 26 at the front of. device- 20 and is secured to the two opposed- .wardly: raised, part 47' which terminates in: a hook-like The actuating bar or upper 4" end portion 48. A lever of a force multiplying leverage mechanism associated with a device 20 has a handle 49 and two integral spaced apart legs 51. The end of legs 51 of the lever, spaced from the handle 49 thereof, are pivotally mounted to the lower grid wall 31 by a pin 52 disposed in a hole provided in hooked end part 48 of this lower wall. This end. of legs 51 of the lever are pivotally connected by a stud or the like 53,.spaced from pin 52, to one end of a pair of links 54 which have their other end pivotally connected, by a pin or, stud 56, to the forward end of bar orupper wall 32 of the longi tudinal grid partition. Stud 53 is adapted to rotate about the pivot pin 52 within a cutaway portion of the hooked end 48 of grid wall 31. Movement of. the legs 51 of the lever in a direction outwardly away from the freezing device 26 rotates the stud 53 about the pivotally anchoring pin 52 and shifts the links 54 and consequently actuating bar 32. in a direction toward the front end of. the
device. and the bar 32 moves or tilts the crosswalls out of.
In accordance with my invention I provide a portable combined freezing device receiving and ice block, storage bucket or receptacle device preferably in the form of an elongated molded plastic transparent box or bucket-like element, generally represented by the reference character 60, for association with the; refrigerator cabinet 10 and removably disposed in the freezing compartrnent or. chamber 14 thereof. The. receptacle or bucket device: 60 includes a plurality of walls.61 forming anice block storage bin in the lower portion thereof (see Figure '6). Long sidewalls of receptacle element or bucketv device 60 are each provided with an integral rail 62, extending parallel to one; another from the front. to the rear thereof The rails 62 form supports on the combined element or bucket device 60 for receiving and supporting portions of the rim of a tray of a freezing. device 20. Front wall 61 of receptacle element or bucket device 60 has a cut-out notch at 63 at its-top edge providing clearance for the leverage mechanism on a. freezing device 20 when sup.- ported on the receptacle or bucket. The back wall of receptacle; or bucket element 60 extends upwardly of the top edge 64 of wall 61 and inwardly over the rear portion of the opposed rails 62 in the form-of a lip 66 (see Figures. 5 and 6). Lip 66 serves a double purpose for the substantially open top receptacle element or bucket device- 60 in that it'provides a handle for transporting the receptacle orbucket from the refrigerator cabinet 10 toa kitchen 'work ledge when desired and provides hold-down means for a freezing device 20 supported on rails or supports 62 'while the leverage mechanism on the device isbeing operated. That portion of the front wall of receptacle or bucket device 60- between its open top edge. 64 and the forward: end of. rails; 62,1 engaged: at either. side of notch.63. by the; brackets 27. cooperate with the handle portion 66 to prevent shifting or tilting of a freezing device 20 with respect to the receptacle or bucket and provides means for holding the tray 21 stationary relative to the element 60 during operation of the leverage mechanism carried by a device 20 supported on the supports 62.
After water has been frozen into separated ice blocks in a freezing device 20 on a shelf 19 within the freezing compartment or chamber 14 of refrigerator cabinet 10 the unitary device together with ice blocks therein is removed from compartment 14, rotated into an inverted position and placed into the open top of receptacle element or bucket device 60 with the top or rim of side walls of the tray thereof supported on the opposed rails or supports 62 as shown in Figure of the drawing. The combined receptacle and ice block storage element or bucket device 60 being portable permits the same to receive a freezing device 20 while it is located in compartment 14 or when it is removed from cabinet and supported on a kitchen work ledge. In order to harvest separated ice blocks from the inverted freezing device 20 on receptacle element or bucket 60 the handle 49 of the force multiplying leverage mechanism is grasped by a hand and pulled in an outward and downward direction relative to device 20 and receptacle 60. This movement of handle 49 pivots legs 51 of the lever about pin 52 and rotates the stud 53 around pin 52 to shift links 54 in a direction forwardly of device 20 and consequently moves actuating bar or wall 32 longitudinally along the grid wall 31. The one wall of notches 38 in actuating bar or wall 32 progressively engages the inclined cross or transverse Walls 33 of the grid structure in tray 21 and tilts these walls one after the other toward the vertical in succession from the front to the rear of the freezing device 20. Tilting of the forward grid wall 33 breaks the ice blocks in the compartments at the front of the freezing device loose from walls thereof and cams them against the inclined end wall 23 of tray 21 whereby they are released or ejected from the freezing device. Subsequent tilting of other of the inclined cross transverse walls 33 breaks the ice bond between ice blocks and tray 21 and these walls. The tilting of walls 33 enlarges the ice block compartments in a direction intermediate these walls and the loosened ice blocks are freed or released from the freezing device 20 by dropping out of the enlarged compartments (see Figure 6). The end portion of lip 4%? on the rear transverse grid wall moves away from the bottom of tray 21 as the wall is tilted toward the vertical and in so moving pushes the ice blocks at the rear end of device 20 out of their compartments whereby to remove all ice blocks therefrom. The ice blocks fall into the storage bin portion of receptacle element or bucket device 69 and then the freezing device 26 is elevated off the rails 62 and removed from the combined receptacle element or bucket device. Receptacle element or bucket 60 with separated ice blocks therein can remain in the freezing compartment 14 of cabinet 10 and ice blocks removed therefrom through its open top as needed or as desired.
From the foregoing it should be apparent that I have provided an ice block harvesting arrangement which can be operated with the ease of conventional means associated with a freezing device and without distorting or twisting a metal tray. By my improved arrangement the fast freezing characteristics of a freezing device of the metal tray and grid type is retained. My arrangement permits harvesting of ice blocks either in the freezing compartment of a refrigerator cabinet or at a kitchen work ledge. Moreover my freezing device is of substantially a conventional design and requires no special or expensive tooling, etc., in its manufacture. The grid remains locked at all times against removal from the tray of my freezing device and does not become misplaced therefrom. A portion of the means which prevents movement of the tray of a freezing device relative to the combined freezing device receiving and ice block storage bucket or receptacle element is formed thereon so as to serve as a handle for transporting the element to or away from the refrigerator.
While the form of embodiment of the invention as herein disclosed constitutes a preferred form, it is to be understood that other forms might be adopted, as may come within the scope of the claims which follow.
What is claimed is as follows:
