FIRE-PLACE.

SPECIFICATION forming part of Letters Fatent No. 359,868, dated March 22, 1887.

Application filed April 3, 1386. Serial No. 197,627. (No model.)

To all whom it may concern:

Be it known that \V6,DOUGLAS P. Lnwis,AunRnwM. JOHNSON, and JOHN W. JOHN, citizens of the United States, and residing in Gin- 5 cinnati,in the county of Hamilton and State of Ohio, have invented a new and useful Improvement in Open Fire-Places, of which the following is a specification.

Our invention relates to heating apparatus;

: and the principal object is to construct an attachment to the ordinary grate or fireplace for utilizing a large per cent. of the heat which ordinarily passes up the chimney and is wasted.

Figure l is an isometric perspective view of I the principal features of this invention and its application. Fig. 2- is a section of the apparatus to show more clearly the circulation of the heated gases.

Similar letters of reference refer to like parts in all the drawings.

Referring to the drawings, the parts A, B, B, and O are hollow castings. The hollow part A forms a hollow lintel, and is usually cost in one piece with the hollow jambs B B. The hollow part of the lintel A is in communication with the hollow part of the jambs B B, at the top, as shown by the front of the rigl1t-hand end of the lintel A being broken away. The hollow jambs B B are in communication with the hollow base or hearth O, as shown in Fig. 1, by the lower end of jamb B being broken away, and by thewletter H in Fig. 2. The hollow base or hearth G, as shown by Fig. 2, communicates with the fine D at I.

At the under side of the hollow lintel A is an opening, J. (Shown in both Figs. 1 and 2.) This opening is almost as wide as the hollow lintel, and extends from the inside of hol- 0 low jamb B to the inside of hollow jamb B.

E is a grate, which can be of any pattern to give the best results to hold the fuel in condition for combustion. The back and side walls which inclosc the grate may be either of brick,

cast-iron, or any other material best suited to the purpose.

At the front of the base O is a door, G, in

which is a register, K. The door is opened whenit becomes necessary to clean out any accumulation of ashes or soot in the base.

The register K, when the door G is closed,

can be opened whenever it is necessary to bank the fire, and by this means the cold air near the floor will be taken up the chimney and the draft at the grate checked to the exact degree desired. By this means, also, any carbonic-acid gas which may be evolved from the grate will be carried along with the current of air at the register.

The hollow lintel A, hollow jambsB B, and hollow base G are usually to be made of castiron about one-quarter of an inch thick, and of a form to give an ornamental appearance.

To understand the Operation of this improvement it must be first understood that the only communication the grate has with the chimney is through the long opening J at the under side of the hollow lintel A. It follows, therefore, that the upward draft in the due is continually supplied by ai r entering the hollow lintel A. lfa tire is built in the grate, theproducts of combustion will rise by the heat, and the inward current at the long opening J will carry them into the hollow lintel A, thence right and left to the hollow jambs B B, and

downward through them to the hollow base or hearth O, and thence back to the rear (see arrows, Fig. 2) and out into the ilue D through the passage I.

It is readily seen that since there is no direct passage up the chimney, like an ordinary fire-place, the heated products of combustion will, in addition to radiating the usual amount of heat, also giveout alargc amount of heat to the hollow parts A B B and base O, which in turn radiate it into the room, instead of wasting it up the chimney; also, since there is no direct draft up the chimney, all accumulations of soot from the flue will fall back in the rear, near the passage I, Fig. 2, and can be taken out through the removable registerdoor at O.

This apparatus combines the heating qualities of a stove with the cheerful appearance of an open fire-place, and will give a maximum 95 degree of heat with a minimum of fuel consumed. On account of the heated gases of jeoting forwardly of the front walls thereof, r 5

the hollow lintel A, open on its under side;

and the hollowjambs B B, opening at their tops into said lintel and at their bottoms into said hollow base, said lintel and jambs being adapted to fit against the lintel and jambs of 20 the fireplace and form a'finishingtherefor.
