GAS-STOVE.

sr'acIFIcAnIoN forming part of Letters Patent No. 537,041, dated April 9,1 895.

I Application filed September 14,1894. Serial No. 523,06 (NO Qd L) To aZZ whom it may concern.- Be-it known that I, LAZARD KAHN, of Hamilton, Butler county, Ohio, have invented certaln new and useful Improvements in Gas- 5 itoves, of which the following is a specifica- 1on.

This invention pertains to improvements in gas stoves for heating, and the improvements will be readily understood from the following description taken in connection with the accompanying drawings, in which- Figure 1, is a front elevation of a gas stove embodying my improvements; Fig. 2, a vertical longitudinal section of the same, in the plane of line a of Figs. 3 and 4; Fig. 3, a plan; and Fig. 4, avertical transverse section in the plane of line b of the other figures.

In the drawings:l, indicates the base or leg-frame of the stove; 2, a, rectangular boxlike body supported thereon and open at the front; 3, vertical flues formed just within the sides of the body and opening at their lower ends into the space underneath the stove so as to receive air therefrom; 4, an open front fireplace formed within the body between the 7 side flues 3; 5, a gas-burner disposed within the fireplace 4 and connected by pipe with a source of gas supply; 6, openings in the floor of the fireplace, under the burner, to supply air for combustion and also air to mingle with the products of combustion; 7, a cross-pipe in the top of the fireplace, extending across from the tops of the two flues 3, a passageway for the products of combustion from the fireplace 3 5 being left to the front and rear of this cross- .pipe, the cross-pipe being a short distance be low the top of the stove-body; 8, flues extending upwardly from the top of the stove-body 2, and communicatingwith the fireplace through 4Q the top of the stove-body; 9, a flue communicating at its lower end with the cross-pipe 7' and extending upwardly; 10, a hollow top or capital surmounting the flues, its interior cavity being in communication with the tops of 5 flues 8; 11, a prolongation of fine 9 through the top 10 but giving no communication with the interior cavity of the top, the top being open or perforated over the fine 9; 12, removable covers in openings in the top D over the fines 8, and 13, a pipe-collar communicating with the interior cavity of top 10, and consequently with flues 8, this pipe-collar being designed to receive the stove-pipe which communicates with the chimney.

The burning gas heats the side fines 3 and also highly heats the cross-pipe '7. Fresh air entering the lower ends of fines 3 therefore becomes heated in its upward passage and goes up through fiue 9 and out into the room through the open or perforated top of that flue at 11, flue 9 and flues 3 also radiating heat to the room and the flames themselves radiating heat to the room. The products of combustion, and airwhich has entered the fireplace and mingled with them, pass around cross-pipe 7 and up through fines 8 to the hollow top 10 and thence out through pipe-collar 13 to 'thestove-pipe and chimney.

The burner 5 may be burned nakedly, or it may have refractory material piled upon it to become incandescent in imitation of a coal fire, and in the latter case a fender, as shown in Fig.1, may be employed to retain this material.

The stove is used in the manner just described when the burner is worked with a mixer which supplies the gas with air before it reaches the point of ignition; but when no mixer is used, or when illuminating gas is burned, then the burner may be elevated in the fireplace and rest upon wall-lugs 14, and covers 12 and the stove-pipe need not be employed. In such case the flame is brought nearer to the cross-pipe 7, and the products of combustion pass upwardly into the room. 3

I claim as my invention- 1. In a gas stove, the combination, substantially as set forth, of a pair of vertical flues open below and forming end walls for an openfront chamber, a gas burner in said chamber, 0 a horizontal cross-pipe over said burner and connecting the tops of said two flues, an exposed radiating flue extending upwardly from said cross-pipe and open at its top, and an in- Y dependent exposed radiating flue having its base in communication with, said open-front chamber above said cross-pipe.

2. In a gas stove, the combination, substantially as set forth, of a leg base, an open front stove-body thereon, a gas burner therein, side lines within said body and open at their lower ends to the atmosphere, a cross-pipe within the body over the burner and communicating with the tops of said flues, a hollow top or capital having an outlet provided with a pipeoollar, flues extending from the hollow of said top and down into communication with the chamber of the stove-body containing the gas burner and said cross-pipe, and a flue rising from said cross-pipe to said top or capital and prolonged through said top or capital and open at its upper end.

3. In a gas stove, the combination, substantially as set forth, of a stove-body open at its front, a gas-burner disposed therein, a crosspipe disposed within the body over the gasburner, side flues within the stove-bodycom LAZARD KAI-IN.
