' i UNITED STATES PATENT CEEICEo WILLIAM' ALLCHIN, OF NEWBURG, NEW YORK.

HOT-AIR DRUM.

Specicat-ion forming part of Letters Patent No. 85,554, dated January 5, 1869.

To all whom it may concern Be it known that I, Wnmmu ALLcHIN, of Newburg, in the county of Orange and State ot' New York, have invented a new and Improved Hot-Air Drum; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawingsforming part el this specification, in which- Figure 1 represents a vertical longitudinal section of my improved hot-air drum. Fig. 2 is a horizontal section of the same, taken on the plane ofthe line a: x, Fig. l. A

Similar letters ot1 reference indicate like parts.

This invention relates to a new apparatus for heating air by the products of combustion that escape from a stove, furnace, oven, or range of suitable construction.

The invention consists in the use of a fiat rectangular drum, which is by interior partitions divided into three zigzag channels, of which the central one serves to conduct the products of combustion to the chimney or Hue, while the outer ones are passages for air,

-which, entering the drum at the lower end in a cold state, become heated by the hot plates and partitions, the latter having been heated by the smoke passing up between them.

A, in the drawing, represents a flat rectangular. drum, composed of two large side plates aa, of two narrow end plates b b, and of a perforated top plate, c. The bottom is opened and may have a flange, d, around it to support the drum, and to conduct the air into the same.

The drum is put up above a stove or furnace of suitable description, and is connected with the smokepipe B of the same.

Within the drum are arranged alternate vertical and horizontal partitions e e, which divide the inside into three, more or less, zigzag passages C, D, and E.

The central passa-ge D is connected with the smoke-pipe B, and the products of combustion pass up through it.

.The side passagesG E receive cold air at their lower ends, and heat the' same as it passes up through them. The horizontal portions ot' the side passages are divided by horizontal plates f f, in order to produce the zigzag pipes, asshowu. The partitions e and fare fastened between ribs', g, formed on the side plates a a, as shown, or otherwise.

Scrapers may be arranged in the horizontal portions of the smoke-liuc D torallow the saine being cleaned.

The hot air escaping from the passages E can, in suitable pipes or tubes, be conducted to any suitable apartment, to be heated, or can be suffered to escape into the same room in which the drum'is put up.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The hot-air drum A, which is by the partitions e and fdivided into three, more or less, zigzag passages, C, D, and E, for smoke and air, substantially as and for the purpose herein shown and described.
