FIREPLACE.

Specification of Letters Patent.

Patented May 18, A1909.

To all Iwhom 'it may concern.

Be it known that I, T norms J. HARPER., a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have made certain new and useful Improvements in Fireplaces, of which the following is a speciiication.

My invention relates to an improvement in iireplaces and is designed particularly to heat two rooms with a single lire, its object being to produce a iireplace which is simple, cheap and ellicient, one which will heat two rooms with a single fire, thus economizing the use of fuel, one which shall consist of few parts, and one which can be readily applied, removed or repaired.

With these and other objects in view, my invention consists in certain nov el l'eatures of construction, arrangement and combination of parts, as will be hereinafter fully described and pointed out in the claims, reference being had to the accompanying drawing, in which#- Figure 1 is a front elevation showing my improved device. Fig. 2 is an elevation showing the rear of the lire back in an adjacent room. Fig. 3 is a vertical section on line 3-3 of Fig. 1. Fig. 4l is a similar section on line add of Fig. 1. Fig. 5 is a rear elevation partly in section, with the rear wall of the fire back removed, and also showing the chimney flue and damper. Fig. 6 is a horizontal sectional view taken on line 6-6 of Fig. 1. Fig. 7 is a sectional perspective view with the rear wall 3 removed.. Fig. 8 is a perspective view of the fire place removed from the wall. Fig. 9 is a perspective view in detail showing the partition. 10 and the damper 15.

In the drawing, 1 represents the ordinary brickwork surrounding the fireplace.

Uy improved .tire back, which consists ofthe front wall 2 and the rear wall 3, leaving a vertical space between them, is Yfitted in the fireplace, the front wall extending forwardly at its upper portion. The improved lire back may be of cast iron, cast with the rear wall 3 integral with the front wall 2, but l prefer to make the rear wall 3 separate from the front and somewhat thinner and to secure it to the side walls 4 of the hollow back by suitable means. The lire back is provided with a cut out portion 5 at one side of its upper portion, and immediately behind this cut out )ortion is the opening 7 in the upper wall S o the lire back.

9 is an opening extending through the liront wall at one side near its top.

10 is a vertical partition cast integral, if desired, with the liront wall, but preferably made separate, which extends `from the top wall of the 'tire back downwardly to .near the floor level, thus dividing the upper 'portieri of the hollow lire back into two tlues or chambers 11 and 12.

T he rear wall 3 oi the lire back, which, as stated. before, is made quite thin, has an open space left at its lower end into which may be slid the ash pan 13, said ash pan being of sul'licient size to extend to the front wall of the lire back.

14 is the chimney flue which connects directly with the cut out portion 5 at one side of the front wall of the fire back, said chimney flue also extending over the 'flue or chamber 12 between the front and rear walls oil the hollow iire back.

15 is a damper secured at one end within the chimney lue, on a rod 16 which extends through the front wall of the brick work 1 of the fire place, and has on its outer end a suitable handle to manipulate it. This damper is just wide enough to cover the cut out portion 5, but does not cover the upper end of the flue or chamber 12.

ln using my improvement, the various parts having been all properly put in place, the `lire is started in any ordinary grate which may be located in front of the lower end of the front wall of the fire back, and the damper 15 is turned to prevent smoking, and allowing a strong draft up the chimney and causing the lire to burn up quickly, the gases and productsof combustion passing up the chimney. As soon as the up-draft has been established, the damper 15 is turned down,l closing the opening 5 which communicates directly with the chimney, whereupon the products of combustion from the lire will pass up into opening 9 into the i'lue or chamber 11, where they are deflected downwardly by the rear wall ol the hollow rire back, passes around the lower end of the partition 1() into the ilue or chamber 12, and thence up the chimney, the heated air in taking this tortuous course, heats the thin rear wall of the hollow fire back to a high degree, and such rear wall, acting as a radiator, will heat the room neXt to it, the improved iireplace having been set in the opening between the two rooms. The ash pan 13 is to catch any ashes or soot that may be drawn over the front wall ofthe iire back;

The damper may be operated by means of the rod and handle as shown, or it may be operated by a pendant attached to it, hanging in the 'lireplace and manipulated by an ordinary iire poker.

It will be observed that the chimney has but one ilue, thus simplifying the construction, and that the partition l0 which begins at the top of the hollow iire back and eX- tends down to the grate level, divides the hollow back into an indirect ilue, beginning at the top of the tire back down and around the lower end of the partition, then up, connecting directly with the chimney flue; this arrangement of parts throws all the heat from the :tire that ordinarily passes up the chimney into direct contact with the inner surface of the thin radiating wall for the other room. One wall or side (the front wall) is the grate iire back, and the other wall (the rear) is the radiator for the other room, said radiator to be protected by an open-work and ornamental fender, if desired.

While, as stated, the hollow fire back may be cast integral, yet it is preferred to make the front and rear walls separate, and to secure them together by suitable means.

Having thus described my invention,

what I claim as new and desire to secure by Letters Patent, is-

1. A ire place for heating two adjacent rooms simultaneously, consisting of a hollow metallic casing comprising top, side, front and rear walls and a central vertical transverse partition extending downwardly from the top wall between the front and rear walls,

but terminating above the hearth level, said front wall having an opening at one side at its top communicating with a chimney flue, and having also at the opposite side near its top an opening communicating with the interior of the casing, said openings being located on opposite sides of the central vertical partition, the top wall of the casing having an opening communicating with the interior of the casing in the rear of the opening communicating with the chimney Hue, said opening in the top wall also having communication with the chimney iiue and means for governing the direction of the ilow of the products of combustion.

2. A 'lire back for hre places for heating two adjacent rooms, comprising a hollow casing, the front wall of which is thick and the rear wall relatively thin, forming a radiating surface said rear wall having an opening at its lower end, and an ash tray adapted to iit in said opening and abut the front wall of the rire back, and means for causing directly heated air to circulate between the said thick and thin walls and finally discharge into a chimney flue.

3. A iire-bacl for fire places for heating two adjacent rooms simultaneously, comprising a hollow casing having a thick front wall and a relatively thin rear wall connected at their upper ends, and a vertical transverse baffle plate or partition between said front and rear walls, the rear wall having an opening at or near its lower end to receive an ash tray, and means for causing the products of combustion to circulate between the said front and rear walls and finally discharge inte a chimney Hue.
