IMPROVEMENT IN SMOKE-HOUSES.

Specification forming part of Letters Patent No. 47,355, dated April 18, 1865.

To all whom it 'may concern:

Be it known that l, WILLIAM HAMILTON, of the city and county of St. Louis, and State of Missouri, have invented a new Safety Smoke-Chamber for Smoke-Houses; and I do hereby declare that the following is a 'ull, clear, and exact description thereof, reference being had to the accompanying drawings and the letters ofreferencc marked thereon.

Figure 1 is a sectional elevation, in perspective, of a smoke-house, a portion ofthe walls of which is broken ont to disclose the safety smoke chamber within. Fig. 2 is a transverse section of one ot' the smoke-chambers.

To enable those skilled in the art to make and use my invention, I will proceed to describe its construction and operation.-

Outside et the smoke house I construct a lire box, A, `of brick or other suitable material. These tire-boxes should have suitable iron doors, a, for closing them up tight. Leading from the tire-box A is the safety smoke chamber B. (Seen through the breach in vthe wall of the building in Fig. l.) The side walls of the sinokechamber are built ot' brick or other suitable material. Vi' hen built otl brick, the walls should be nine inches thick, andthe bricks so disposed in the several courses as to leave an open space, t, clear through the wall between=every brick. lhese openings tshould be ot' the thickness of the course of the brick in which they are constructed, and their length should be about half the length ofthe brick. A similar construction might be made in stone or iron, but I prefer the use of brick. A brick arch should be thrown over the top of the smoke-chamber, as shown clearly in Fig. 2. These arches will ordinarily be constructed of one thickness of brick, and several feet of that portion of them nearest the `firebox should be of lire-brick. The lining of the fire-box will also be of fire-brick. be an iron plate, x, projecting over the side oi' the walls ot' smoke-chamber from the base of the arch. The smoke -chambers should be constructed in the bottom of the smoke-house below the joist d, on which the meat is placed to be smoked. The fire being built in the Iire box A, entirely outside ot' the house, a great portion vot the heat will be retained outside,

-and not injure the meatduring the process ot' smoking. The sparks which may arise from the tire will be likely to expire in the smokeY chamber; but if any of them should pass out of the openings t, their upward flight will be arrested by the projecting iron plate fr, and f the building will thereby possess great in1Inu nity from danger by re.

Having described my invention, I elai1n-` M. RANDOLPH, A. WAGNER.
