H. REHAHN, OF NEI/V YORK, N. Y.

IMPROVED REFRIGERATOR.

Specification forming part of Letters Patent No. 20,895, dated July 12, 1858.

To @ZZ whom it may concern.-

Be it known that I, HENRY REHAHN, of the city, county, and State of New York, have invented certain new and useful Improvements in Refrigerators; and I do hereby declare the following to be a full, clear, and exact description of the arrangement and operation of the same, reference being had to the accompanying drawings, making a part of this specification, in which- Figure l represents a perspective view of the refrigerator. Fig. 2 represents a vertical section through the same. Fig. 3 represents a horizontal section.

Similar letters of reference where they occur in the several figures denote like parts of the refrigerator in all of them.

To enable others skilled in the art to make and use my invention, I will proceed to describe the same with. reference to the drawings.

The refrigerator maybe of an octagonal form and composed of wood, with solid or hollow walls, and lined with zinc in any of the usual well-known ways. The top of the refrigerator has double or two doors A B, the former opening over the ice-box C and the latter over a chamber D in the rear of and around the ice-box. One of the sides of the refrigerator has three doors E E E, which open,re spectively, to the three open shelves F F F, so as to readily get at the articles thereon.

Over the'icefbox C sits a water-cooler G, with a pipe d leading therefrom, on which a faucet or drawcock may be placed to draw out water. From the ice-chamber C there passes a coldair tube or pipe I, as seen in Fig. 2, down through the center of the refrigerator, and the bottom of this pipe is furnished wit-h openings, out of which t-he cold air may pass, and as it becomes warmed it rises, passing up through the openings in the shelves F and the articles upon them, and finally escapes through the register J, which can be regulated at pleasure for a greater or less current of air through the interior of the refrigerator. The shelves F have sleevesc at their centers, which slip over the pipe I and rest upon flanges c on said pipe,'and this allows the shelves to be freely turned around either way to bring any article upon them next the door. The lower shelf may have partitions in it for receiving bottles,

the necks pointing toward the center of the interior chamber.

The whole interior of the refrigerator can be lifted out at the top of the box by removing the top thereof, and thus it can be thoroughly cleaned in all its parts.

f is a drippipe leading from the ice-box down to the bottom thereof, and may be furnished with the usual bend or goose-neck to prevent the air from passing up it into the ice-chamber.

It will be perceived that, in addition to the zinc lining to the box, there is a round zinc case g within the box, which leaves spaces h between it and the angles of the sides of the box. In the bottom part of this zinc case g there is a series of holes 't' i, &c., which lead into these spaces h, and thus a current of cold air also passes up behind the inner case, as well as through it, and this air from behind the case also finds its exit at the register J with the air that comes up through the center of the refrigerator. By this arrangement I both cool and ventilate the inside of the refrigerator, and I have besides the inside of the case a chamber D underneath the top, which chamber, being in close proximity to the ice, is valuable for smaller articles that might get impregnated with other grosser ones in the main chamber, from which it is entirely separated.

Having thus fully described the nature and object of my invention, I would state that I do not claim circulating the air through the ice and through the refrigerating-chamber, as that has heretofore been done; but

What I claim herein as new, and desire to secure by Letters Patent, is'- In combination with the ice-box and ventilator arranged near the top of the refrigerator-box, the centrally-located cold-air tube for carrying the cold air from said ice-box down to or near the bottom of the refrigerator and admitting it into the refrigeratingchamber and in between the inner and outer cases, whence it ascends and escapes through the register, substantially as herein set forth and described.

HENRY REHAHN.
