NATURAL-GAS HEATER FOR FlRE-PLACES.

SPECIFICATION forming part of Letters Patent No. 386,391, dated July 17, 1888,

Application filed February Q5, 1588. Serial No. $65,255.

To all whom, t may concern.:

Beit known that I, JOHN M. ELLIsoN, a citizen of the United States, and a resident of Allegheny City, in the county ofAllegheny and State of Pennsylvania, have invented certain new and useful Improvements in Natural-Gas Heaters for Fire-Places; and I do declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specitication.

Figure l of the drawings is a representation of a front elevation of my improved fire-place. Fig. 2 is a vertical section on line m, Fig. l. Fig. 3 is a vertical section through one end wall. Fig. ais a top view of chamber D.

The object of this invention is to provide apparatus of economical and effective character for heating and Ventilating houses or apartments thereof; and the invention consists in the construction and novel combinations of devices,all as hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letter A designates a fire-place having hollow side walls, B, and back wall, C, and provided also with the hollow sloping top D, which is sepaated by the throat V from the transverse connection or girder Il, which is preferably of arched form and extends across from the front portion of one of the hollow side walls to the front portion of the other; and I sometimes provide atransversc vertical partition between the front portion of the chamber in said side wall and the back portion, dividing the same into a front lue, F, and a back flue, G, which communicate by the opening a in said partition. Gold air is conducted into said chamber or flues and enters at the inlets b b, near the lower ends of said chamber or iues, as shown. When the back wall, C, is hollow, as preferred, it is designed to provide an opening for communication near the top of the back wall at each side thereof, as at c c, whereby the air may enter the back chamber from the side chambers. A tubular passage, d, leads from the back chamber to the sloping chamber H in the hollow inclined top D, which covers in the back portion of the tire-place, as

(No model.)

shown. Openings c e are also made at the ends of the hollow top in the floor thereof, to admit hot air Afrom the chambers or rear tlues of the side walls. Usually I. provide ribs K K in this top tlue between the end portions and middle thereof to strengthen the parts. rIhese ribs, however, have passages at g g, whereby communication is established between the end portions and middle part of said sloping chamber. In the bott-om or floor of said sloping chamber is also an inlet, h, which receives the end of a pipe, k, whereby con'nnunication is established between this sloping chamber and the hollow heater L, which is secured in the tire-place. This heater is designed to be ot' sectional construction and to have somewhat the appearance of a coil or grating. Usually I provide two coils, N N, which are arranged side by side, and are provided with laterallyextending pipes or conneetionsl, which engage openings in the inner walls of the tire-place at the sides thereof. to establish communication between the side tlues or chambers and the sectional heaters. These heaters are also provided with rearwardly and upwardly extending pipes or connections m, which may be again connected by a union, c, from which a pipe, 7c, extends to the top chamber, or the single pipes m may connect directly with the ioor ofthe top chamber.

In building the heater it is preferred to use short pieces of straight pipe, as at a, and elbows or unions e, into the ends of which the straight pieces of pipe are secured, each section forming, as indicated, a sort of coil, preferably, through which the air from the chambers in the side wall courses, being heated in its passage by the llames of the natural gas or other combustible which play around and about the heater L, raising said heater to a high temperature. The air thus heated passes upward into the chamber in the sloping top D, and being there mingled with the warm air from the hollow back and sides of the ireplace, may be conducted off through openings l s and suitable pipes or passages in connection therewith to heat other apartments, while the apartmentin which the lire-place is located is heated by the burning gas and the heater L, whose temperature is raised thereby. The burner-opening for the natural gas is indicated at J. I is the spreader. For Ventilating purposes it is designed to provide, in connection with openings in the front walls of the side fines of the fire-place, registers R, which may be regulated to graduate the ad mission of air from the room into theseside chambers, according to requirement.

Having described this invention, what I claim, and desire to secure by Letters Patent,

1. In a fire-place for natural gas having `hollow sides and top, a sectional pipe heater,

L L, in said re-place having lateral pipe-connections leading to said sides and upwardlyextending pipe-connections leading to said top, substantially as specified.

2. The combination, with areplace having natural-gas burners and hollow side walls, of
