IMPROVEMENT IN FIRE-PLACES.

Specification forming part of Letters Patent No. 171,067, dated December 14, 1875; application filed October 29, 1875. 7

To all whom it may concern:

Be itknown that 1, ROBERT THOMPSON, of Stapleton, in the county of Richmond and State of New York, have invented a new and Improved Fire-Place, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a front view, and Fig. 2 a vertical transverse section on the line 0 c, Fig. 1, of my improved fire-place.

Similar letters of reference indicate corresponding parts.

The object of my invention is to construct an improved fire-place, by which the heat, which generally escapes through the chimney, may be utilized in a more perfect manner, and a pure, moist, and warm air supplied to the rooms above or on the same floor.

The invention consists in combining a chamher, having air inlets and outlets, with an angular shelf arranged at the back thereof, as hereinafter more fully described.

In the drawing, A represents a metallic fire wall or plate, which extends vertically from the bottom plate at some distance from the floor to a point at a level with or above the grate B, that is attached to the side walls of the lire-place, and provided with ash-pan. fender, &c., in the customary manner. The fire-wall A is formed above the grate B with an angular projection, O, that extends forward, and slants then backward in upward direction to the main wall. At the rear of the firewall A, back of the grate, may be arranged alternating shelves, for conducting the air along the same. A forwardproiecting angular part or shelf, D, of the wall, made of bricks, or metal plates, forms, in connection with the front wall A, an air-chamber, E, which is supplied with cold. air by suitable air-flues from the outside, through the floor or from the inside of the room, as shown in Fig. 2. The apex of the angular rear wall- D is below the angle of the fire-wall, and approaches close to the same, so as to form a narrow air-flue, that connects the lower part with the upper part of the air-chamber, and throws, by the lower inclined part of the shelf D, the cold air directly on the heated fire-plate.

If the air-flues a to below the fender are not employed, the air may be drawn in through a double flue, 1), formed by a horizontal partition, d, as indicated by arrows in Fig. 2.

The air-fines supply the air-chamber E, and also the air-chambers, which are-arranged at the sides of the fire-place, if such may be desired.

A water pan or receptacle, F, is placed back of the front wall A, into the lower part of the air-chamber E, for the purpose of supplying the required amount Of moisture by evaporation. The water-receptacle F is filled with water from time to time through a recess, 6, of the fire-wall, and a sliding or swinging gate, 0, for closing the same.

The slanting upper part of fire-wall A serves for the purpose of preventing the soot or ashes from settling thereon, so that no non-conducting layer is formed which \vould'diminish the heating capacity of the fire-wall.

The slanting top part of fire-wall A is connected, by tubesf, with a collecting-drum, Gr, above the same, which communicates again by tubes passing up through the chimney, with the room above, or by tubes passing through the front or side walls, to the room already heated by the grate-fire.

A flue, Z, of the rear wall, below the slanting plate of the fire-wall, conducts the heated air to the adjoining room or to the outside, whenever the air should not be required for heating purposes. The drum Gr may be dispensed with, and the conducting-tubes placed in direct connection with the rooms to be heated.

The air-chamber supplies a pure, moistened, and heated air to the rooms on the same or next floor, and produces thereby, by the use of the same amount of fuel, a more perfect utilization of the products of combustion.

Having thus described my invention, 1 claim as new and desire to secure by Letters Patent- The combination of the angular shelf D and air-chamber E, the two respectively arranged in relation to each other, in a fire-place, as and for the purpose set forth.
