REFRIGERATOR.

SPECIFICATION forming part of Reissued Letters Patent No. 9,742, dated June 7, 1881.

Original No. 218,783, dated August 19, 1879. Application for reissue filed April 12, 1881.

To all whom it may concern:

Be it known thatl I, GYRUS B. SHAW, of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in Refrigerators; and I do hereby declare the following is a full, clear, and exact description of the invention, that will enable others skilled in the art to which it appertai-ns to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The object of this invention is to furnish improved refrigerators, ice-boxes, ice-houses, Src., which shall be so constructed as to use less ice than refrigerators constructed in the usual way, be more easily kept clean and sweet, and be more easily repaired when required, and which shall be simple in construction, inexpensive in manufacture, and convenient in use.

In carrying out my invention I employ the mechanisms and devices as fully illustratedin the accompanying drawings, which form a part of this specification, and in which- Figure l is a top plan view, partially in section; Fig. 2, a vertical section through the line .r wof Fig. 1, and Fig. 3 a vertical section of the same through the line y y of Fig. l.

Referring to the drawings, in which similar letters of reference indicate like parts in all the figures, A represents the box or case of my improved refrigerator, which may be made plain or paneled,as may be desired, and is supported upon short legs B, to raise its bottom from the ground and form space for the drip-pan.

The inner surface of the box or case A is lined with slabs O of plaster-of-paris, which are cast and allowed to set in molds of the required shape -and size. The lower and side edges of the slabs C are halved, dovetailed, or

otherwise jointed to each other, so as to formclose connections, and to keep the said slabs in place.

The upper ed ges-of the slabs CV are held in place by rabbeted cleats D, which are detachably secured to the inner sides of the upper edges of the box A, so that by detaching said cleats any or all of the slabs C may be detached and replaced by new ones. It will be observed that the removable slabs are non-con duetors of heat, and that the cleats D serve an importantfunction in connection with said noneonducting slabs.

The doorway is surrounded with cleats E, which are rabbeted to receive the edges of the slabs O. The door (marked F in the drawings) is also lined or provided with a non-conducting slab, of plaster-of-paris or the like, which is kept in place by rabbeted cleats D, attached to the inner sides of the edges, and the upper one of which is detachable, so that the liningslab may be conveniently detached and replaced at will.

To the upper edge of the box A are attached cap-cleats G, the inner edges ot' which project beyond the inner surfaces of the lining-slabs O to form a seat for the rabbeted edges of the inner cover, H, which is hin ged at its rear edge to the rear cap-cleat, G. The coverH isliued with a plaster-of-paris slab, C, which is kept in place by rabbeted cleats D. The forward cleat D is detachable, so that the slab C can be readily removed when desired.

'Ilo the upper sides of the outer parts of the cleats G are attached cap-cleats I, which surround the edges of the cover H and form a sea-t for the outer cover, J. The cover J is 'hin ged at its rear edge to the rea-r cap-cleat I and has dan ges or cleats K attached to its side and front edges to overlap the upper parts of ofthe sides and front of the box A.

In the projectinginner edges ot' the rear and front cap-cleats G are formed dovetailed or other notches or recesses to receive corresponding connections.

The rack M is made rectangular in form, and with open-work or skeleton sides and ends to allow the air cooled by the ice to pass down into the lower part of the box A. The rackM is made with an open-work or skeleton falsebottom, N, at a little distance above the true bottom O, to receive the ice and allow the water from the melting ice to drop to the said true bottom O.

The bottom O has a plaster-of-paris slab, P, placed upon it, which slab is coucavechto adapt it to receive the drip-water and conduct it to the drip-pipe, which passes out through the bottom or side of the box Ain the usual way, as indicated in dotted lines in Figs. 2 and 3.

In the ice-rack M, upon the middle part of the false-bottom N, is placed a vessel, Q, to serve as a reservoir for Water to be cooled for drinking purposes. The reservoir Qshould be made of earthenware or some other material that will not oorrode, and will not affect the water, and of such a size as to leave sulcient space between it and the sides of the rack M to receive a suitable supply of ice.

In the drawings, the reservoir Q is represented as being cylindrical in form; but Iprefer to make it rectangular, as forming bettershaped spaces to receive ice.

In the lower part of the forward side of the reservoir Q is formed a hole to receive the faneet'R, which passes in through a hole in the forward side of the box A, so that the cold water can be readilydrawn out, as required.

With this construction the Water in the reservoir Q will be kept cool, and will be free from the objections of having ice-water mingled with it.

What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A removable non-conducting lining for refrigerators, of plaster-of-paris, made in sections and jointed to match each with the other, combined with a holdingease, a removable top, and a hinged door having similar lining, substantially as and for the purposes set forth.

2. The frame A, combined with an outletpipe, R, from a reservoir, Q, the removable lining-slabs 0,01? plaster-of-paris, dovetailed orjonted, as shown, the door F, and hinged cover J, having similar lining, all constructed and arranged as and for the purposes set forth.

3. The combination of the cleats G, having dovetailed notches, the dovetailed bars L, and the rack M, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.
