BENJAMIN F. AVERILL, OF DUNKIRK, NEW YORK, ASSIGNOR OF ONE-HALF OF HIS' RIGHT TO LEE LORD HYDE, OFSAME PLACE;

lMPROVEMENT IN REFRIGERATORS.

Specification describing certain new and useful Improvements in Refrigerators and Milk- Coolers, invented by BENJAMIN FRANKLIN AVERILL, of Dunkirk, in the county of Chautauqua and State of New York.

Nature of the Intention.

The object of my improvement is to obtain a constant downward circulation of dry cold air through the refrigerator from top -to bottom, and to prevent any contact of the air with the ice; and the invention consists in the construction and arrangement of the iceboX and certain parts, as hereinafter fully eX-l plained.

General Description.

In the drawing, Figure l is a vertical section. Fig. 2 is a cross-section of the ice-box, Ste. Fig. 3 is a plan of the ice-box, &c; Figs. 4 and 5, detail views.

A represents the refrigerator-case, made, in any suitable manner as to form and filling of the walls. Above and partly sitting in the refrigerator is the ice-box B, the bottom of which is made in trough-shape, so as to allow the drippings from the ice, and also the 'water condensed on the outside, to flow downward into the dripper D. This latter is made slantin g to readily carry oif the water (see Fig.

2,) either through the waste-pipe a, or a faucet, as may be desired. There is an open space, 13, leftbetween the ice-box walls and the contiguous walls of the refrigerator, as well as a space between the dripper and bottom of the ice-box. The object of this is important,

as it is for the purpose of getting aconstant very cold, and, in this state, passes through the'nozzle or opening d into the body of the refrigerator in a very dry and cold state, and

is there diffused and radiated throughout the entire inside. The upper mouth e will be protected `by a screen to prevent the entrance of iiies, insects, &c. I

To get the necessary circulation through the refrigerator, and to produce a draught, the bottom of the case A is provided with an outlet or escape pipe, E, which also has a wire-cloth screen to prevent ies, dirt, &c., from entering.

y The doors F of the refrigerator are made in the usual manner, with the addition of aband of rubber, c, or its equivalent, running around the outside, or set into a groove around the inner edge, to come in contact with the jamb, and thus make the joint air-tight. To make this packing more' effective I make the, socket f for the lock or catch g inclined 'inward from the top, so that the tongue or bolt h, (see Figs. 4 and 5,) when turned, will act on an inclined plane, and thus force the doors inward. The

lid or door F of the ice-box B is also arranged in this manner.

The operation of the refrigerator is very simple. The air in the pipe G, getting cooled,

passes downward, and is being constantly re- Y placed by the air from above through its mouth cand, passing into the interior of the refrigerator through opening d, keeps a dry pure air in it always. By mysimple method all odors are carried off, and a constant circulation of dry cold air is kept up, as before stated.

What I claim is- The ice-box B, constructed substantially as shown, and inclosing the return or coil air-pipe C, with its induction-mouth c outside, and the eduction-mouth d inside the refrigerator, the whole arranged and operating in the manner and for the purpose hereinbefore set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
