HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 538,899, dated May 7, 1895.

Application filed January 24, 1894. serial No. 497,848- (No model.)

. of which the following is a full, clear, and exact description. reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is a front elevation of my improved gas-stove partly broken away. Fig. 2

is a horizontal section; and Fig. 3 is a vertical section on the line III III of Fig. 1, showing the stovein combination with a fire place.

In the drawings, A represents the fire-back of the stove, which is preferably of a plane surface, constructed of sheet-iron or cast-iron, coated with asbestos wool, or having a polished metallic radiating surface. At or near to the lower end of the fire-back may be perforations a, a, for the admission of external air. The burner consists of a tube 6, arranged longitudinally, and detachably supported from the fire-back A by hooks e which project from the fire-back, as shown in Fig. 1. On the upper side of the burner-tube e, are perforations or jets e for the passage of the gas, which is ignited on its escape therefrom. The gas is admitted by a gas nipple a, furnished with a valve or cook, over which nipple is a funnel or air-mixer d entering the lower side of the burner-tube c. There may be two or more such gas nipples similarlyarranged, if desired. The burner-tube e may be covered over in front by a curved plate or fender f. At the top of the fire-back A and projecting forward from it, is a hood or cowl g, which receives the heated air and products of combustion of the gas, conducting them through a short connecting pipe or pipes g into the upper end of a chamber B, which is or may be constructed of sheet metal or other suitable material, and which is plate-like in shape, 11. e., of relatively greater width than thickness and about the same width as the fire-back A, so that the products of combustion shall pass therethrough and in wide stream, and not as if a mere pipe were used to conduct the gases from the fire-back.

The chamber B is made separate from the fire-back so as to afford an intervening open air-circulating space 1) between them, and is connected thereto by bolts B. The fire-back A and its hood or cowl constitute an open front heating-chamber.

The stove is set immediately in front of a vertical plate H of sheet-metal or similar material which closes the front of the fire-place opening I, and from the lower part of the chamber B a pipe it extends through the plate H, there being an intervening narrow space J between the plate H and the back of the chamber B for the circulation of air and for the radiation of heat from the front of the plate H. This arrangement insures a good draft for the eduction of the products of com bustion. The'stove is held in position by suitable means, consisting preferably of a catch K, consisting of a pivoted slotted plate bearing against the elbow of the burner-pipe which is separate from the stove, together with plates or rods L, which project from the back of the chamber B and bear against the face of the plate H. When this catch is in the position shown in Fig. 1 bearing against the burner-pipe, it prevents the stove from being movedoutwardly, while the rods L pre-' vent it from being moved back. The stove caneasily be moved, however, by lifting the tube e, raising the catch K on its pivot so as to disengage it from the burner-pipe, and then moving out the stove. This part of my invention may be modified in various ways within the scope of the claims.

The heated products of combustion from the heating-chamber A enter the top of the chamber B through the pipe g, pass downwardly through said chamber and escape through the pipe h, and in doing so the heat is radiated from the stove into the intermediate air space from the back of the firechamber A and the front of the chamber B, and is also radiated from the back and sides of chamber B, and from the plate H, which is heated by the products of combustion which pass up the flue I. In addition to this, there is direct radiation from the face of the fireback A, so that the heating capacity of the gas is utilized to the greatest degree possible. For this purpose, the stove is set out in the room as shown, and not directly in a fireplace, and the chamber B is of greater crosssectional area than the area of the pipe h, so that the gases shall be retarded in their escape from the chamber B.

As I have stated, the burner-tube e is detachable from the stove, and from the gas-jet or jets, so that when desired the stove may be used for the purpose of illumination and ventilation without giving out much heat, the naked gas-jets, without the air supplied by the air-mixer 61, giving light, and the as cending column of heated air passing into the hood g and thence through the chamber B out to the chimney, thus ventilating the apartment.

The advantages of my invention will be appreciated by those skilled in the art.

\Vithoutlimiting myself precisely to the described form and arrangement of the parts, what I claim is-
