Application February 14, 1933, Serial No. 656,767

7 Claims.

This invention relates to tools'or implements for removing frozen ice trays from mechanical refrigerators and has for its object generally to improve and simplify the constructionof such implements whereby to reduce the cost of manu facture and increase the efiiciency thereof.

A further object of the invention is to provide an implement of the class described including a standard having a series of notches formed in -one side thereof which cooperate with an operating lever to form a fulcrum for the latter when removing an ice tray, .said lever being adjustable vertically of the standard whereby to adapt the tool for removing trays of different -makes and heights.

A further object is to provide means for preventing accidental separation of the coacting units comprising the tool so that" they will always be properly assembled for immediate use, and means whereby thetool may be conveniently suspended from the wire shelf 'of a refrigerator when the tool is not in use.

A further object is to offsetthe lower end of the standard so that'it will assume a position,

' in front of and adjacent the bottom of the tray to be removed and thereby facilitate dislodgment of said tray from deposits of frost or ice when the operating handle is depressed.

In the accompanying drawing forming a ,part -of this specification:

Figure 1 is a side elevationpartly in section, of a tray releasing tool constructed in accordance with the present invention, showing the operating lever in position beneath the reinforcing bead of an ice tray.

Figure 2 is a top plan view of the tool or implement detached.

Figure 3 is a front elevation of the standard.

Figure 4 is a transverse sectional view taken on the line 4-4 of Figure 1.

Figure 5 is a transverse sectional view taken on the line 5-5 of Figure 1.

Similar numerals of reference indicate corresponding parts in all the views of the drawing.

The improved tool or implement forming the subject matter of the present invention comprises an operating lever 5 preferably arcuate in cross section and having one end thereof terminating in a handle 6 and its other end "provided with a terminal upwardly inclined lip '7 adapted to extend beneath the reinforcing bead 8 of an ice tray indicated at 9. The front connecting the side walls of the lever immediately beneath the slot vll is a transverse bearing pin 12. Associated with the lever 5 is a standard 13 preferably formed of sheet metal and U-shaped in cross section, as shown in Figure 4 of the drawing, thereby providing parallel arms 14 having a series of downwardly and inwardly inclined notches .15 formed therein and opening through the outer longitudinal edges of the arms, as shown. These notches 15 preferably extend substantially the entire height of the standard and are adapted to selectively receive the transverse pin 12 of the operating lever whereby to form afulcrum on which the lever tilts in the act of dislodging a tray. The lower end of the standard 13 is preferably offset laterally at '16 and extended downwardly to form a foot 1'? adapted to rest on the ice or frost in front of and adjacent the bottom of the tray 9 whereby to facilitate dislodgment of said tray when depressing the lever. The metal constituting the arms 14 is inclined downwardly in opposite directions, as indicated at 18 and connected by a transverse bar 19 forming a part of the foot. By making the lower end of the standard in this manner .acomparatively wide foot will be produced so as to form a firm foundation for the standard and prevent rocking or tilting movement thereof when operating the tool. The offset xportion of the standard is provided with a reinforcing rib 20 which gradually merges into the standard at the bend of the U-shaped portion and also into the foot, thereby to reinforce and strengthen the same. In order to prevent slippage of the standard on the frost or ice within the refrigerator, the foot thereof is provided with a pad 21 preferably formed of rubher, one end of the rubber constituting the pad being extended upwardly at the rear of and in contact with the foot 17 and the other end of the rubber being bent inwardly to form a yieldable locking lip 22 which fits within the hollow portion of the foot and bears against the adjacent side walls thereof. In case the pad 21 becomes worn or otherwise damaged from constant use it may be readily removed by deflecting the lip 22 laterally until it clears the foot and a new pad may then be inserted. The metal at the upper ends of the arms 14 is preferably bent laterally to form retaining ears or stops 23 which serve to prevent accidental separation of the two units comprising the tool so that they will always be properly assembled for immediate use. The end of the handle 6 of the operating lever is also preferably provided with a rearwardly extending hook 23 by means of which the tool may be conveniently suspended from the wire shelf of a refrigerator when the tool is not in use.

The upper tooth 24 formed by the adjacent notch 15 preferably terminates short of the upper end of the standard 13 and the outer edges of the arms 14 are preferably curved laterally at 25 to assist in guiding the lever to its proper position on the standard when assembling the tool, it being of course understood that after the lever is assembled on the standard, the stop ears 22 will be pressed laterally to prevent sepa ration of the units, as previously stated.

When the device is to be used for removing relatively shallow frozen ice trays the standard is positioned in front of the tray with the lip 7 of the operating lever extending beneath the reinforcing bead 8, after which a downward pressure is exerted on the operating handle which elevates the tray and permits its ready dislodgrnent from the ice or frost should the tray adhere thereto. In order to remove trays of greater height than that shown in Figure 1 of the drawing, the standard is positioned Within the refrigerator in the manner previously stated and the operating lever adjusted vertically on the standard until the lip '7 of the operating lever engages beneath the reinforcing bead of the ice tray to be removed and the pin 12 engages the corresponding notch, after which the handle of the operating lever is depressed in the manner previously described.

It will of course be understood that the tools may be made in diiferent sizes and shapes and either cast or stamped from sheet metal without departing from the spirit of the invention.

Having thus described the invention, what I claim is:

l. A device of the class described comprising a standard substantially U-shaped in cross sec tion and provided with a series of vertically disposed notches, an operating lever fulcrumed on the standard and provided with a transverse pin adapted to engage a selected notch in the stand ard, and stop ears formed on the standard to prevent accidental separation of said standard and lever.
