Application May 14, 1932, Serial No. 611,395 16 Claims. (c1. 62-1085) My invention relates to mechanical refrigerators andmore particularly it relates to a device for facilitating the removal of ice cube trays from mechanical refrigerators.

It is 'well known that considerable difiiculty is encountered in loosing and removing ice cube trays from the freezing unit of household mechanical refrigerators. This inconvenience is caused by the formation of ice between the trays and freezing unit causing the trays to firmly adhere to the unit. Heretofore it has been the common practice to loosen the trays by inserting a pointed kitchen utensil between the trayand the freezing unit and pry the tray from the unit. Such practice damages both the trays and the freezing unit and is often ineffective, and um mately requiring the use of heat to loosen the trays. Other means, such as cam and lever devices, built into the freezing unit have been proposed for loosening the trays but have met with little success because the devices themselves become frozen tight and are very difficult to operate. Morever these devices are expensive to manufacture because it is necessary to reconstruct the entire freezing unit in order to install them.

It is therefore an object of my invention to provide an improved device conveniently mounted in the refrigerator which will easily loosen and remove ice cube trays from the refrigerator without injury to either the refrigerator or the trays.

Another object of my invention is to provide a device of this class which may be quickly and easily installed in a refrigerator, at any time, and in such a manner that it will not be in the way,

' nor become frozen to the freezing unit, when not in use.

Another object of my invention resides in an improved ice cube tray removing device which is compact, durable and simple-of construction, economical to manufacture, readily installed in a standard refrigerator, and easy and efficient in operation.

These and other objects and advantages of my invention willbe apparent from the following description, reference being had to the accompanying drawing, wherein several embodiments of my invention are illustrated. It is to be understood that my invention is not to be limited to the specific embodiments herein illustrated and described, reference being had to the appended claims for that purpose.

In the drawing:

Fig. 1 is a perspective view of a portion of a r mechanical refrigerator embodying my inven-. tion;

This connecting member is preferably in the may be readily adjusted vertically for selective Fig. 2 is a fragmentary side elevational view of a mechanical refrigerator illustrating the position of the implement when not in use;

Fig. 3 is a similar view illustrating the operative position of implement;

Fig. 4 is a perspective view of an embodiment of my invention, and

Fig. 5 is a fragmentary side elevation of a modified support.

Referring to the drawing in detail, a standard mechanical refrigerator is illustrated at H] with the door open, so as to show the relation of the elements of the present invention with the con-- ventional refrigerator with which it cooperates including a freezing unit, generally indicated at 1 II and forming a. freezing chamber I2 which is divided into sections by a plurality of shelves l3 adapted to support a plurality of ice cube trays l4, having the usual handles l5. Thefreezing unit is provided with the usual guard or shield plate l6.

The embodiment of my invention illustrated in Fig. l which cooperates with the above men- 'tioned refrigerator parts is generally indicated by the reference character 20, and may be mounted on a bracket 2! which in turn is secured by screws'22, or the like, to a stationa y part of the refrigerator. In the illustrated embodiment the bracket as shown is attached to the shield l6 adjacent the ice cube trays ill but it is to be understood that the bracket could as well be at- 0 tached to any other part of the refrigerator or could be built into the walls or top of the refrigerator and be within the scope of the invention. The bracket 2| is formed with a forwardly projecting arm 23 more clearly shown in Figs. 2, 3 and 4, and having a depressed central portion 24. A slot 25 is preferably stamped out of the arm 23 and terminates at its inward end in an'enlarged portion 26. A connecting member extends through the slot and is so constructed and arranged as to slide freely through'the enlarged portion 26, but to be gripped by the narrow slot 25 at a plurality of points throughout its length.

form of a chain 21 as illustrated, the individual links of which will serve as the gripping abutment for engaging the narrow slot 25. The lowermost end of the connecting member is connected at 28 to a lever or implement 3!], but may i be secured to the implement or lever 30 at. any point intermediate its ends depending upon the amount of leverage desired. Chain 2'! thus pro- 1 vides a support for the implement 30 whereby it tray desired from its support. Moreover, such support enables an operator to swing the implement across the front of the trays to engage that portion of the tray most tightly frozen in and dislodge it from its support. The opposite end of the chain carries a ball 29 which is of a size suflicient to prevent its passing through the enlarged portion 26 of the slot. The implement 30 is formed at one end with a hooked portion 3| with which an operator may engage a tray to pry it loose from the shelf, and at the opposite end with a handle 32 to be grasped by the operator when the removal of a tray is desired.

Normally the implement 30 may rest in the depressed portion of the arm 23, as shown in dotted lines in Fig. 1 and full lines: in Fig. 2. When it is desired to remove one of the ice cube trays which may be solidly frozen in the freezing unit, an operator may first remove the implement from the arm 23 and then adjust the chain in the enlarged portion 26 of the slot 23 until the desired vertical position of the implement 30 in front of the trays is had. A link of the chain is then slid into the narrow slot portion 25 of the arm 23, to lock the chain against any vertical movement relative to its support. The operator may then grasp the handle 32 and engage the hooked end of the implement either with the underside of the tray handle, as shown in Fig. 3, or beneath the tray, if the tray does not have the usual handles. A slight downward pressureis now exerted on the implement, the connection 23 acting as a fulcrum for the lever action of the implement 30, which will dislodge or loosen the tray and cause it to slide outwardly on the shelf so that the operator may then grasp the handle of the tray or the tray itself and withdraw it from the shelf.

Referring to Fig. 5, I have shown ,a modified embodiment of my invention wherein the bracket 2| may be dispensed with and a support for the flexible member formed by a circular opening 35 cut in the shield-or guard I 6. A portion of this opening should-be large enough to permit the chain to be adjusted therein, a narrowed slot portion 36 being provided to retain a single chain link against relative movement of the chain in the slot when the device is in use. This form of the invention is preferably employed in refrigerators while under construction.

While the embodiment of my invention herein disclosed constitutes a preferred form, it is to be understood that other forms may be adopted,

such as for instance, the employment of arigid rod or flexible rod in the place of the chain 21,

all coming within the scope of the claims.
