(Ci. 62l) 1 Claim. t

The invention pertains to refrigeration apparat-us and more particularly to means for conveniently and quickly removing ice and frost from a cooling element, as well as boosting the effectiveness of the element.

in some types of refrigerating apparatus, such as frozen food storage units. it is not possible to shut down the machine and permit the frost and ice to melt. In open top refrigerator cabinets divided into storage compartments by means of vertical partitions the frost and ice commonly form on the upper edges of the refrigerated partitions. It has been usual to use a wire brush or other tool for removing such ice and frost which may then fall down into the stored goods.

it is accordingly an object of my invention to provide a convenient defrosting arrangement for refrigeration cooler members.

It is also an object of my invention to provide a defroster-booster element which may be conveniently applied upon or removed from refrigerator cooler members for quickly removing the frost and ice therefrom, as well as boosting the effective field thereof.

in accordance with my invention. the portion of the refrigerator cooling member which usually becomes coated with ice is covered with a snug fitting defroster element. This is made of good thermal conductive metal so that it becomes a secondary refrigerating surface while in snug contact on the cooler member. In operation of the refrigerator the frost and-ice deposits on this defroster-booster element. To defrost the refrigerator it is then only necessary to pull ofi this element and hold it under the water tap to melt off the ice. The element is then reinstalled, as by pressing it upon the cooler member where it is preferably a snug resilient fit.

Further objects and advantages will be apparent and my invention will be more readily understood by reading the following specification in conjunction with the appended drawing, in which: a

Fig. 1 is a side elevational view showing a refrigerator cooling member or partition plate provided with my defroster, the dotted lines also representing it in a removed position;

Fig. 2 is an enlarged fragmentary end view with a deposit of ice shown by dotted lines; and

Fig. 3 is a similar view showing the defrosterbooster element removed from the refrigerator cooler member.

Referring more specifically to the figs. of the drawing, I have illustratlvely disclosed my invention as applied to the upper edge of a conven- 2 tional refrigerated plate type partition it, such as is commonly utilized between the storage con-1 partments in open top frozen food units (not shown). Such a cooler member has conduits it extending for connection with a suitable source of refrigerant.

in accordance with my invention i provide a defroster-booster element it comprising an elongated web strip ll adapted to fit on and along the edge of the refrigerated partition. Projecting from the edges of this web strip I provide a pair of opposed wings is extending suitably spaced to snugly fit over and engage opposite sides of the refrigerated partition. These wings it are sufficiently resilient to hold the defroster element snugly upon the partition while also facilitating installation or removal of the defroster element. While the defroster is installed, these resilient gripping wings it also serve to provide good thermal conductive contact on the partition and also to provide an extensive surface to receive the ice and frost 2i, shown dotted, and removal of the iced element is facilitated because this resilience permits the element to be broken loose by a side tilting movement, as represented by dotted lines in Fig. 3.

As shown, I may conveniently make the defroster element of a piece of sheet metal of suitable thickness to afford the desired strength and resilience. This is very easily accomplished by bending up edge portions E of the metal sheet and then giving it a reverse bend forming a double fold at D so that the downturned edges extend down below the web strip ill to form the resilient wings it. The upwardly extending double folds D may also serve as air cooling fins boosting or extending the effective range of the refrigerated partition ll, whereon the defroster element is installed.

' Fig. 3 shows how conveniently the defroster element is pulled off of the edge of the refrigerated partition, thereby removing the ice and frost which commonly issuch a nuisance on the upper edges of such refrigerated partitions. It is then only necessary to hold the defroster element under a water faucet to melt off the ice and frost. after which it is again clipped upon the edge of the refrigerated partition.

It is apparent that within the scope of my invention modifications and different arrangements may be made other than herein disclosed, and the present disclosure is illustrative merely, the invention comprehending variations thereof.

What is claimed as the invention is:

A defroster-booster for the exposed edge of a 3 refrigerated partition comprising, a piece of sheet metal bent to form an elongated web strip adapted to flt on and along the exposed edge or the partition and having reversely bent folds extending along opposite edges 01' said web strip and projecting to opposite sides thereof for gripping the edge or a refrigerated partition at one side while extending away from the partition at the other side.
