SPECIFICATION forming part of Letters Patent N o. 449,692, dated April 7, 1891.

Application filed July 26, 1890 Serial No. 359,994. (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 Fire-Place Heaters, of which the following is a specication. Y

This invention relates to certain improvements in re-place stoves, which are hereinafter rst described and then claimed.

Referring to the accompanying drawings, Figure l is a front elevation of the stove, a portion at one side being broken away. Fig. 2 is a vertical section of the stove. Fig. 3 is a top view of the stove. Fig. 4 is a view of the stove on the horizontal line 4 4, seen in Fig. 2. Fig. 5 is a View of the top part on the horizontal line 5 5. Fig..6 is a horizontal section on the line 6 6. Figs. 7 and 8 are also horizontal sections on the lines 7 '7 and 8 S, respectively.

The letter A designates the front plate of the stove; B, the cylinder which projects partly forward and partly backward of said front plate; O, the front frame of the stove, and D the chamber for the ash-drawer. The combustion-chamber of the cylinder extends from the grate E as high as the doorway F, where a horizontal plate G is fixed at the front part. The rear wall B or one-half of the cylinder is continued upward to a crownsheet II, and each side B2 of said rear wall projects straight forward above the said horizontal plate G to the front frame C. NVindow-openings a are in these side walls B2. At the front of the cylinder just above the grate is an opening b for access to the grate to remove clinkers, dac. .The crownsheet II forms the top of the combustionchamber and also the bottom of a hot-air chamber I, above which is a chamber J for gases and products of combustion. A direct smoke-flue K leads from the lower combustion-chamber B up past the top air-chamber I to a gas-chamber J. A damperL at the top of the said smoke-flue is shifted by means of a rod L', and thereby the smoke-flue is opened and closed. The front side walls c of the air-chamber form at each side an indirect smoke-fine d. These two ues lead up and communicate with openings d in the bottom plate M of the gas-chamber J. A smoke-pipe N leads from the gas-chamber J at a point directly over the top of the direct smoke-flue K. Both the direct flue K and the indirect lues d carry smoke and gases from the cylinder B to the smoke-pipe N, and all of these tlues lead to the gas-chamber J. The position of the damper L determines the course the smoke and gases will take.

In the top plate M of the hot-air chamber I are two hot-air openings e e', one on either side of the same. These openings allow the hot air to pass into ues leading to the upper apartments of the house. Two dampers M for closing or opening said dues e e are operated by rods f. A third hot-air opening g is in the front portion of the top plate M and allows a portion of the hot air to escape into the room.

Below the horizontal plate G and extending from the front frame C back to the front plate A at an angleare two side walls C. These walls also extend down to a horizontal plate E', forming part of the top of the ashchamber D. The side walls C have windowopenings n. Adjoining the front frame C below the said plate E are two side walls P, which extend back and on an angle to the front plate A. These walls extend down to the base-plate V of thel stove and have airinlet openings h. The rear wall B of the cylinder also projects down to the base-plate V of the stove and forms the back wall of the ash-chamber D. Each side D of the said rear wall between the base-plate and grate E projects straight forward and forms the side walls of the ash-chamber.

Between the side walls D of the ash-chamber and the two outside walls P below the horizontal plate E is formed an air-chamber R, one at each side of the stove. Through the inlets h in the walls'P air passes from the atmosphere into the air-chamber R just described. Air-outlet holes h in the top plate Eof the air-chamber allow air to pass therefrom to a second air-chamber S, formed by the side walls C', the front plate A, the front frame C, the front wall of the cylinder B, and the horizontal plate G above and the plate E below. The air by coming into contact with the cylinder B is heated in this air-chamber S, and holes 7l in the horizontal plate G and outside of the side walls B2 allow a portion of ICO the said heated air of this hot-air chamber to escape into the room in which the stove is placed.

Surrounding the rear wall B of the cylinder B from the base-plate to the top of the stove and extending at each side to the front plate A is a jacket T, which forms an airheating chamber U, which connects with the air-chamber I above the crown-sheet H. Air from the atmosphere enters this chamber U through holes j in the base-plate Vaud from the air-chamber R through holes k in the front plate A, one on either side of the stove. Air passes into the air-chamber U from the air-chamber S through an opening or hole l.

Surrounding the jacket T is an outer jacket T, which extends from the base-plate V almost to the top ot the stove. This jacket is semicircular and extends to the front plate A on either side.

The air-chamber U', formedbetween the two jackets T T, has at the top av partial covering m, having a small spacem only open. Air from the atmosphere enters this chamber Uf through holes j in the base-plate. Air also enters this chamber U from the chamber R and atmosphere through the holes 7c in the front plate A on either side of the stove and also from the air-chamber S through the holes Z, one in either side of the front plate A. The two rear air-chambers U U', formed by the jackets T T and the rear Wall B of the combustion-chamber B, are independent of each other. rThe outermost one U has no connection with the other air-chamber U or the upper air-chamber I, but connects only .with lines leading to the upper apartments of the house, so as to allow hot air to pass4 upwithout being affected by the dampers h which control the hot air passing from the chamber I through the openings e c', which connect with the fines leading to the upper apartments of the house.

The direction ot' movement of the currents ot' air is indicated by the darts in the different figures of the drawings.

Having described my invention, I claim- 1. In a tire-place stove, the combination of the combustion-chamber B, a hot-air chamber I directly above the combustion-chamber and having openin gs e e leading to flues to supply upper apartments, dampers M', controlling said openings, a gas-chamber .I on top of the said hot-air cl1amber,two separate vertical airchambers U U extending from the base-plate to the top, one of them connected with said upper hot-air chamber I and the other leading to tlues which supply the upper apartments, and a base-plate having two sets of openings, each admitting cold air into a different one of said vertical air-chambers.

2. In a fire-place stove, the combination of the combustion-chamber B, a hot-air chamber I directly above the combustion-chamber and having in its top plate openings e c leading to flues to supply upper apartments, dampers IVI', controlling said openings, a gas-chamber .I on top of the said hot-air chamber, and an air-heating chamber U to supply upper apartments independent of the air-chamber I and not controlled by the said dampers'M, as set forth.

3. In a fire-place stove, the combination of the combustion-chamber B, an air-chamber R on each side of the ash-chamber, and an air- `chamber S above and communicating with t-he side air-chambers and having openings t' to allow hot air tov escape into the room, as

and` for the purpose set forth.

4. In a lire-place stove, the combination of the combustion-chamber B, a hot-air chamber I above the combustion-chamber and providedV with outlet-openings e c leading to fines to supply upper apartments, a hot-air chamber U, connected with said chamber I and partly surrounding the combustion-chamber B, dampers M for controlling the said outletopenings, andan air-heatingchamberU outside of said chamber U to supply air to fines leading to upper apartments independent of the air-chambers U and I and the dampers M', as and for the purpose set forth.

In testimony whereof I atx my signature in the presence of two witnesses.

JOIIN B. OLDERSIIAV.
