PATENT JOHN B. OLDERSHAIV, OF BALTIMORE, MARYLAND.

Al R-H EATING STOVE.

SPECIFICATION forming part of Letters Patent No. 449,691, dated April '7, 1891.

Application filed July 26, 1890- Serial No. 359,993. (No model.)

To all whom it may concern.-

Be it known that I, JOHN B. OLDERsHAw, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Air-Heating Stoves, of which the following is a specification.

This invention relates to an improved airheating stove, which is illustrated in the accompanying drawings, in which' Figure l is a side elevation of the stove. Fig. 2 is a vertical elevation of the same. Fig. 3 is a plan view of the stove as seen when the top is removed at the line 3 3. Fig. 4 is an inverted plan of the stove-top, that part above the line 3 3. Fig. 5 is an upper side view of the stovetop.

The object of this invention is to provide a heating-stove with such construction as will increase its capacity to heat air.

The letter A designates the base, which may be of any design or pattern; B, the cylinder inclosing the combustion-chamber B, and C the grate.

The ash-receptacle D is in the base.

Within the walls of the cylinder and Hittle below the top thereof is a crown-sheet or fire-plate E, which forms the top of the combustion-chamber B and also the bottom ofa hot-air chamber F, the top of which is formed by the plate G.

Abo've the top hot-air chamber F is a chamber H for gas and other products of combustion.

A direct smoke-flue I leads from the combustion-chamber B up past the top air-chamber F to the gas-chamber H. A damper J is at the top of the said smoke-flue I and is shifted by means of a rod J', whereby the smoke-flue may be opened and closed.

The top air-chamber F has a wall Z at the front, which extends therefrom part way around at each side, and thereby forms two indirect smoke-fines m, each at a side opposite the other, which lead up to the gas-chamber H. Openings m are in the top plate G and register with the indirect smoke-fines m.

A semicircular shell or jacket K forms an air-chamber K, which incloses the back wall of the cylinder B. The jacket of this back air-chamber forms a vertical front face n at each of two opposite sides of the cylinder B,

and at the bottom cold-air inlets 0 lead to the back chamber.

The top hot-air chamber F and the back air-chamber K'are in communication by two side spaces 10, which are between the direct smoke-flue I and the two indirect smokeflues m.

A hot-air outlet q at the front part of the hot-air chamber F provides for the escape into the room of all the air that may be heated in either the back chamber K or the top chamber F. e

A smoke-pipe 1" leads from the gas-chamber H at a point adjacent to the top of the direct smoke-flue I. Both the direct flue I and the indirect flues m carry smoke and gases from the combustion-chamber B to the smokepipe 7', and all of these flues lead to the gaschamber H. When the damper J is closed, all the products of combustion will escape by the side or indirect flue m, and thereby the front walls of the cylinder will be more intensely heated by the hot gases in the chamber B before said gases pass to the top gaschamber H. The gas-chamber H assists to heat the room in the same manner that the front part of the cylinder B and exterior of jacket K doby direct radiation.

A boiler-hole s is in the top plate of the gaschamber back of the center of said chamber and immediately above the top of the direct smoke-flue I.

In the drawings an ornamental device If is seated over the boiler-hole 8. Upon removal of this a kettle or boiler may be placed over the hole, where the full effects of the heat will be obtained.

Having described my invention, I claim 1. A cylinder-stove having a combustion- -chamber B havin a crown-sheet E a to a z: a p

gas-chamber H, a hot-air chamber F between the said crown-sheet and gas-chamber, a smoke-pipe 4", leading from the back of the gaschamber, a back smoke-flue I, leading from the combustion-chamber direct to the said smoke-pipe,-a damper to control this flue, and two side smoke-fluesm from the combustion-chamber to the gas-chamber, as set forth.

2. A cylinder-stove having a combustionchamber B, having a crown-sheet E, a top gas-chamber H, a hot-air chamber F between the said crown-sheet and gas-chamber, a

smoke-pipe '1', leading from the back of the gas-chamber, a back smoke-fine I, leading from the combustion-chamber direct to the said smoke-pipe, adamper to control this flue, and the top plate of the gas-chamber provided with a boiler-hole .9 back of the center of said chamber and immediately over the top of the said back smoke-fine.

3. The combination of acombnstion-cylind er having a crown-sheet E, a top gas-charnber H, a hot-air chamber F between the crownsheet and gaschamber and provided with an outlet q, and a semicircular jacket K,incl0sing the back Wall of the combnstion-cylinder and forming there a hot-air chamber which is in communication with the said hot-ai r chamber above the crown-sheet.

In testimony whereofI a'lfix my sign atnre in the presence of two Witnesses.

JOHN B. OLDERSIIAW. "Witnesses:
