BENJAMIN F. ADAMS, OF BROOKLYN, NEW YORK.

REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 271,391, dated January 30, 183,

Application filed July 24, 1882. (No model.)

To all whom it may concern:

Be it known that I, BENJAMIN F. ADAMS, a citizen of the United States, residing in the city of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Refrigerators;

and I'do hereby declare that the following is a full. clear, and exact description of the same.

The object of my invention is to produce an ice-box or refrigerator which will utilize both the ice and the ice-water caused by the melting of the ice for cooling and condensing purposes, so thata low degree of temperature may be obtained and the air in the refrigerator be kept dry at the same time.

My invention consists essentially in an inner lining formed into corrugations and arranged on two or more sides of the interior portion of the box, and the combination therewith of anice'chamber at the top of the box, having its floor of a single thickness of metal, inclined in opposite directions at suitable angles to cause the water from the melting ice on the upper side and the moisture produced by condensation on the lower side of said floor to pass to the outer side of said corrugated lining without dropping into the body of the box and without the aid of an extra piece of metal or covering.

The accompanying drawings illustrate amode of carrying out my invention.

Figure lis avertical sectional view, looking toward the front of a refrigerator provided with myimproved lining and ice-chamber. Fig. 2 is a vertical section taken in the line 00 0c of Fig. 1. Fig. 3 is ahorizontal section taken in the'line y y of Fig. 1. Fig. 4 is a horizontal section taken in the line z z of Fig. 1. Fig. 5 is a detail view.

The outer casing,A, may be of wood or any other suitable material, and the metal lining,

' B may be attached thereto in the usual or any suitable manner. The ice-chamberG is at the top of the box, and is formed by the lid and sides of the box and by a plate, E, constituting the floor of the chamber. This plate or floor E is formed of a single thickness of metal, the object of which is to have a surface in the upper part of the box that will always be as cold as the ice which lies on the top of it, thereby distributing cold air from the most advantageous part of the box-namely, the topand allowing it to fall through the entire inner portion to the bottom of the box. The plate or floor E is inclined downward in opposite directions at a suitable angle-say about forty-five degrees-to enable it to carry off the drippings from the melting ice on the upper surface and the moisture of condensation on the lower surfaceyand deposit the same on the outer surface of the corrugated inner lining. The object in having said floor inclined at so great an angle is to carry the moisture of condensation along the under surface to the outer side of the corrugated lining without the aid of another piece of metal or covering for the purpose of catching the dripping moisture, which extra covering would keep the cold air from passing down through the inner portion or body of the box. If the corrugated lining is applied to only two sides of the box, the floor E is inclined in only two opposite directions, as shown in Fig. l; butif the corrugated lining is applied to all four sides of the box the floor E is inclined in such directions as to communicate with all four of said sides.

The inner lining, G, may be formed in a single piece on each of the sides to which it is applied,as shown in Figs. 1 and 2; or it may be formed of slats or strips, as shown in Fig. 5, in which latter case the slats or strips may be arranged to touch each other or to drip one upon another, as may be preferred. In either case the corrugations or slats are so arranged that the drippings and moisture of condensation may be distributed evenly and uniformly over the entire surface of the inner lining, and pass slowly down until they reach the bottom of the box, upon which they drop from the lower edge of the lining, and are conducted by a gutter, h, to an escape-pipe, z, leading from said bottom. This can be accomplished by having the corrugations either horizontal or inclined in zigzag form. The object in having the inner lining corrugated and placed in such a position as to receive the drippings from the ice-chamber at the top is to cause the ice-water from the ice-chamber and the moisture from the under surface of the floor to flow slowly back and forth over the corrugated surface until it reaches the bottom of ICO the box, which process will extract from the ice, the water, and the moisture of condensation a'll the cold which is of any value.

hen an extremely low temperature is desired-as, for exam ple, for preserving ice-cream or for similar purposesthe space between the lining B and inner lining, Gr, may, if desired, be packed with fine ice and salt.

This invention may be readily applied to ice-houses and refrigerating cars, barges, or vessels of any description.

What I claim as new, and desire to secure by Letters Patent, is-

In a refrigerator, an auxiliary lining for the food-chamber, consisting of corrugated plates separated by space from the walls of said chamber, and adapted to receive at their upper outside surface the waste water from the upper and lower surfaces of a superimposed ice'chamber, and to conduct the same through the space between said auxiliarylining and the walls of the refrigerator, substantially as described.

2. In a refrigerator, the icechamber 0, consisting of the walls A and the sloping floor E, adapted to form a roof or top to the food-chamber, in combination with horizontally-corrugated plates or strips G, located at one or more sides of the food-chamber, and adapted to receive at their upper outside surfaces the waste water from the sloping top, and to conduct the same to suitable collecting-gutter in the floor or bottom of said food-chamber, substantially as shown and described.
