UNITED' STATES PATENT OEEICE.

JOSEPH H. RAOEY, OF NEW YORK, N. Y.

IMPROVED REFRIGAERATOR.

Specification forming part of Letters Patent No. 89,243, dated April 20, 1869.r

To all whom t may concern:

Be it known that I, J osEPH H. RAGEY, of the city, county, and State of New York, have invented a new and useful Improvement in Refrigerating-Ohambers, of which the following is a full, clear, and exact description, reference being had to the accompanying draw- A ing, forming part of this specification, and in which- Figure l represents a plan of a refrigerating-chamber constructed in accordance with my improvement, having its upper portion removed 5 Fig 2, a vertical section through the lille x .fr in Fig. l, and Fig. 3, a similar section through the line'y y. Fig. 4 is a sectional plan through theline z z in Fig. 2.

Similar letters of reference indicate corresponding parts.

My inv-ention consists in a combination of a corrugated roof to the chamber in which the articles .designed to be preserved are placed, with side receptacles or pockets formed of waved or.corrugated plates, united at their ends, and of a tapering or converging character, so as to be apart internally at their tops, where said pockets join the roof, but gradually approaching each other below, where the pockets open intoor connect with horizontal troughs that serve to contain the water produced by the melting of the ice or frigorific mixture that in stocking the refrigerator is piled in the pockets and on the corrugated roof. By this construction a most efficient cooling action is obtained, with great strength of Y structure.

The invention also consists in a novel arrangement of double doors to the preservingchamber of a refrigerator, by making the inner door or doors to open inward, while the outer door or doors open outward, and whereby, when the inner and outer door are both packed or lined with a suitable non-conductor, as is the case with large refrigerators or refrigerating-chambers, the outer door may be made smaller, and greater convenience generally attained than when the inner door is also made to open outward.

Referring to the accompanying drawing, A represents the outer wall or case of the refrigerating-chamber, and B the inner shell thereof, with asuitable non-conducting packing in between them. O C are lids, which are also packed, and through which the ice or frigo riiic mixture is introduced onto a corrugated roof, D, to the preserving-chamber, or interior E of the refrigerator, and within side pockets F F. This corrugated roof is preferably of a double-inclined form, so as to slielve toward and join or connect with either side pocket F F. These side pockets are essentially of the character and construction described in Letters Patent No. 80,766, issued to me August 4, 1868, the same being formed of waved or corrugated plates a a, united at their ends, and of a tapering or converging character, so as to lie more apart at their upper edges, and less so below where the corrugations on the opposite sides of the pocket may meet.

. The'bottoms of these pockets open into or communicate with horizontal receptacles or troughs G G, that serve to hold water produced by the melting of the ice, and should be provided with suitable waste-pipes, also with a vertical pipe or pipes, to allow of the escape ofv cool air or gases generated therein into the body of the structure, so as to cause a circulation and expel the warmer air through a suitable vent in the top of the refrigerator.

The tapering form of the corrugated pockets not only prevents the ice which is broken or ground to a given size from settling too low or rapidly, but the pockets so constructedpresent a large cooling-surface within a comparatively small space, and which increases in an upward direction, where the air is `naturally warmer.

The corrugated roof D further provides, and this in a most efficient manner, for cooling the upper portion of the interior chamber, and, when taken in connection with the side pockets F F, to'which said roof forms au ice-feeding surface, a most perfect refrigerating-chamber is produced. v

H H and I I are inner and outer doors to the interior E of the refrigerator. These doors, which are suitably packed in common with the body or walls of the chamber, are hung and arranged so that the inner door or doors open inward or within the refrigeratingchamber, while the outer door or doors open outward, as represented by red lines in Fig. 4.

This arrangement, as regards the opening and D with the corrugated tapering side pockets,

F F, and lower Water troughs or receptacles, Gr Gr, substantially as specified.

2. The combination, with the refrigerator constructed, as described, of inner and outer doors arranged to open in reverse directionsthat is, the outer door or doors to open outward and the inner door or doors to open inward relatively to the chamber of such refrigerator, essentially as herein set forth.
