REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 268,493, dated December 5, 1882.

Appncation nied'september 25,1882. (No model.)

To all whom it may concern Be it known that I, RALPH S. JENNINGs, of the city anlil county of Baltimore, of the State of Maryland, have invented a new and useful Improvement in Refrigerators 5 and I do hereby declare the same to be described in the following specification and represented in the accompanying drawings, of which- Figure l is a front elevation, Fig. 2 a rear view, and Fig. 3 a horizontal section, of the series of shelves and their surrounding cooling-case 'appertaining to my invention. Fig. 4 is a transverse and vertical section ofthe refrigerator.

The nature of my invention is defined in the claims hereinafter.

In this refrigerator each of the shelvesis hollow and contains a horizontal partition, which is disposed midway between the top and bottom of the space iut-he shelf, but does not extend entirely to the front of such space. The portion of the space which isimmediately over the partition opens into a dat tube or conduit that leads therefrom nearly upto the top ofthe chamberin which the shelves are placed. The portion of the space which is below the partition opens directly into a chamber in rear of it, within which is a perforated platform or grid for sustaining ice.

In the drawings, the outer case of the refrigerator is shown at A as having openings a in its-front provided with doors b. In rear ofthese openings, and between such and the cold-air chamber c, provided, as described, with the ice-sustaining grid d, is the series of hollow shelves e, within each of which is a partition,f. The pipes that lead upward-from the spaces over the partitions are shown at g in Figs. 2, 3, and 4. Furthermore, the series of shelves has extending up through it at its middle a hollow partition, h, which opens into a hollow casing, t', surrounding the series of shelves, except at the front and rear thereof.

I he hollowcasing, as well as the vertical hollow divisional and shelf-supporting partition, freely communicates with the spaces within the hollow shelves, in order that cool air received within 4the shelves may circulate Within the casing and hollow partition to aid in cooling the spaces between `the shelves.

the shelves.

There is to be in the wooden casing, at one end thereof, an opening provided with a door,

its partition and escapes by means of the pipe I leading upward from each partition nearly to the top of such chamber. Becoming raised in temperature in its course, the air flows over and upon the ice, and by contact therewith falls in temperature, and again descends-Within the chamber to again enter and pass through The lowermostshelfof the series is at or just above the bottom of the surrounding wooden case, such shelf constituting the bottom of theucooling space or spaces immediately over it.

By this construction of the refrigerator it becomes divided into a series of cooling apartments or spaces between the shelves, which,

if desirable,.may be provided with separatedoors, in order that when access may be desirable to any one of such apartments it may 'be had without having to open any of the 2.
