REFRIGERATING CABINET.

Application liled March 10, 1924. Serial No. 698,030.

Y 10 all whom t may concern Be it known that I, Lnn H. PAYNE, a citizen oi' the United States, residing at Milwaukee, in the county of Milwaukee and State ot' llliscoiisiii, have invented certain new and useful Improvements in Refrigerating Cabinets, of which the following is a specilication.

This invention relates to a cabinet for maintaining at a low temperature products, such as ice cream, and the like, and particularly to a refrigerating cabinet in which ice in subdivided form is packed around a container for the goods.

It has heretofore been proposed, tor the purpose of econoinizing in t-he consumption or' ice, to limit the vertical dimension of the mass of ice which surrounds the container by excluding the ice from the lowerY portion or' the container-receiving space and using the latter as a brine well, and d ependingon the salty water which develops' from the melting of the ice to keep the lower portion of the container' cool; and the object ot the present invention is to provide a construction of refrigerating cabinet operating upon this principle, but which will be of simpler construction and more eliicient in the cooling capacity of the brine well. Accordingly, the present invention proceeds upon the principle of having the transverse dimensions of the brine well sufficiently near to those ot the end of the container, which enters the well, to adapt the container to serve as the ice excluding element, although suliciently larger than the container to develop an elicient brine circulating space around the inner end of the container; but this brine circulating space is of such restricted capacity that the contained liquid cooling medium, namely, the brine, will circulate therein and be replaced by cooler' liquid from the ice pack as fast as the imbalance in temperature develops, and thus not only is the ice eX- cluded from the brine well without the complication of special partitioning means, gratings, and the like,but the brine is prevented roin accumulating around the inner end of the container in any such volume as would admit of local circulation and interference with replacement of brine from the melting ice. Means are introduced between the inner end of the container and the walls of the brine well for maintaining distance ot' all the walls of the two members, and thus insuring continuity of the brine well entirely around the container; and these spacing means extend beneath the container so as to prevent it resting on the bottom of the well as well as at the sides thereof, as,

for instance, by developing the spacing means in the form of straps extending along vertical walls ol the container and having deflected ends that enter beneath the container.

In the accompanying drawing`- Figure l shows, in vertical section, a relirigerating cabinet embodying the several features of the present invention.

Figure 2 is a horizontal section on the line QX-X of Figure l; and

Figure 3 is a detail view, in perspective, showing one of the straps for spacing the container in the Well.

l represents a refrigerating cabinet constructed with inner wall 2, outer Wall 3, and heat insulating material 4 between said walls, and 5 represents a container for goods to be kept cool by means of a packing 6 ot' ice surrounding the container. According to the present invention, the interior space of the cabinet l, in which the container 5 is received, is subdivided into an ice chamber 7 which, while completely surrounding the container 5, is nevertheless terminated short ot the lower end ot the container, and said lower end is accommodated in a brine well 8. Vhile that portion of the inner wall 2 of the cabinet which develops the ice chamber 7 is spaced a considerable distance from the container 5 in order to admit the substantial mass ot ice, the relative transverse dimensions ot the brine well 8 and the lower end of the container 5 are suoli as to leave a Space between these members that is too small to admit of pieces of ice although sufficient to permit brine,which naturally settles from the ice pack, to substantially surround the container and insure cooling of the lower end thereof.

In order to uniformly space the lower end of the container from the walls of the brine well 8, straps 9 are symmetrically distributed in said' space, preferably at the corners, when the opposed walls of the container and well constitute the sides of a polygon, and these straps have their ends 10 deflected-beneath the bottom of the container 5 so that they keep the latter from resting upon the bottom ol the well S, and excluding brine from the bottom space.

I claim l. In a refrigerat-ing cabinet, an ice-receiving chamber, a brine well at the inner end of and of less transverse dimension than said chamber7 and a container extending trom the chamber into said well and of a dimension which leaves between the container and the walls of the well a space that will not admit ott ice but which is sutlioient to permit brine from the ice chamber to circulate therethrough; means being provided in the brine well Ytor spacing the walls o't the container and brine well at intervals? and maintaining the brine space around the container.

ln a retrigerating cabinet, an ice-receiving chamber a brine wellat the inner end,

of and of less transverse dimension than said chan'iber, and a container extending from the chamber into said well and ot a dimension which leaves between the container and the walls of the well a space that will not admit; oit icev butK which is su'tticient to permit brine from t-he ice chan'iber to .circulate therethrough; means being provided in the brine Well for spacing the walls et the container and brine well at intervals. and maintaining the brine space around the container; said means being located beneath the endas wellas at the sides ot the container.

Inr a refrigerating cabinet, an ice-receiving chamber, abrine well at the inner end of and of less transverse dimension than said chamber, and a container extending from the chamber into said well and ot a dimension which leaves between the container and the walls ofthe Well a space that will 'not admit o-tice but which is sulicient to permit brine from `the ice chamber to circulate therethrough; means being` provided for spacing` the walls of the container and brine well at intervals, and maintaining the brine space around the container; said means comprising straps distributed at intervals around the container.

et. In a` refrigerating cabinet, an ice-receiving chamber, a brine well at the inner end ot and of less transverse dimension than said chamber, and a container extending trom the chamber into said Well and of a dimension which leaves between the container and the walls oit the well a space that will not admit ot ice but which is sutiicient to permit brine from the ice chamber to cir culate therethrough; means being provided for spacing the walls of the container and brine well at intervals, and maintaining the brine space around the container; said means comprising straps distributed at intervals aroundlthe container, and i having their ends deliected beneath the container and supporting the container above the bottom ot the brine well. l

ln a retrigerating cabinet, an ice-receiving chamber, a brine well aty the inner lend ot and ot' less transverse dimension than said chamber, and a container extending trom the chamber into said well and of a dimension which f leaves between the container and the walls oft' the well a space that will not admit o tL ice but which is sui'iicient vto permit brine trom' the ice chamber to circalate therethrough; means beingprovided within the brine well for spacing the walls ot the container and brine wellat intervals, and maintaining the brine space around the container; the brine well "being of polygonal transverse section1v and the spacing means being located at the corners of the polygon.
