THOMAS (1 SMART AND JOHN E. LYNCH, OF DETROIT, MICHIGAN.

HEATING AND LIGHTING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 766,775, dated August 2, 1904,

Application filed January 9, 1904. Serial No. 188,410. (No model.)

To (LU 'whmn it warty concern.-

Be it known that we, THOMAS G. SMART and J OHN E. LYNCH, citizens of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Heating and Lighting Apparatus; and we declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specifieation.

This invention relates to heating and lighting apparatus; and its object is to produce a heating apparatus that not only cokes the fuel before burning, but also utilizes the gases formed in the coking-chamber for lighting purposes; and its novelty consists in the peculiar arrangement and combination of parts hereinafter more fully described and claimed.

In the drawings. Figure 1 is an elevation, partly in section, showing a stove arranged for both heating and lighting. Fig. 2 is a plan, partly in section, of a stove with the cover removed. Fig. 3 is a section on line a of Fig. 1, showing the slide in the bottom of the coking-chamber.

A is a coking-chamber. The coal is first placed in this chamber and a fire started in the fire-pot B with any kind of material suitable for the purpose. The heat thus generated not only warms the room in which the stove may be placed, but also cokes the coal in the coking-chamber, which is made practically air-tight for this purpose. The gases produced in this chamber pass out through outlet I) and pipe P into the reservoir N, from which leads a pipe to gas-jet O. There is only one jet shown in the drawings; but it is to be understood that any number may be used, depending upon the size of the coking-chamber and the amount of gas produced.

By making the gas-pipe P sinuous in form the heavier constituents of the gas, such as tar, &c., will more readily separate from the lighter, in fact purifies it to a certain extent, and the gas that passes into the reservoir is of better quality for lighting purposes.

A pipe L is connected to pipe P and leads to the fire-pot B, so that all by-products separated from the gas drop into fire-pot B and are consumed. The pipe P is also provided with a check-valve T(shown in dotted lines in Fig. 1) to prevent the gas from flowing back into the stove.

e have found it advisable upon starting the fire to open the slide F and allow the heavy gases which are first formed in the cokingchamber to pass through the chamber G and opening H into the fire-pot B, where they are nearly, if not entirely, consumed, the residue, if any, passing out through chimney O, which leads directly from the heatingor flame chamber. This flame-chamber is above the fire-pot B and entirely surrounds the cokingchamber A. As soon as the coal begins to coke the slide F is closed, and the gas then passes through pipe P into reservoir N, as above described.

If at any time it is found desirable not to use the gas for burning in fire-pot B or for lighting, the slide F being closed, the slide E is opened, and the gas passes directly from outlet D into chimney C.

When the coal in the coking-chamber has been thoroughly coked, the slide K is withdrawn, allowing the coke to drop into the firepot B. The coking-chamber A is made larger at the bottom than it is at the top in order that the coke may drop very freely. By replacing slide K and filling chamber A with fresh coal the coke which has been dropped into the fire-pot B is burned to again produce coke and gas in chamber A, as heretofore described.

The slide K is arranged with a cast piece M, which closes the opening in the outside wall of the stove when slide K is closed, as shown in Fig. 3. This opening is made in the wall of the stove to allow the slide K to be nearly or entirely withdrawn, if necessary.

At the bottom of chamber G a door R is provided, through which soot, &c., may be taken from stove. The door Q is provided to enable operator to see into fire-pot B, and through draft-door S the ash-pan I may be withdrawn.

\Vhat we claim is 1. In a heating and lighting apparatus, the combination of a fire-pot, a heat or flame chamber, a coking-chamber a storage reservoir for gas, a passage-way connecting the cokingchamber and the storage-reservoir of suchform as to purify the gas, and a channel or chamber connecting the passage-way to the storage-reservoir and the fire-pot, said channel or chamber being provided with a slide or damper at its upper end and a door at or near its lower end, substantially as described.

2. In a heating and lighting apparatus, the combination of a fire-pot, a heat or flame chamber surrounding the coking-chamber, a cokingchamber, provided with a sliding bottom, and made larger at the bottom than at the top, a storage-reservoir for gas connected to the coking-chamber by a gas-pipe sinuous in form and provided with a check-valve and drippipe joined to the gas-pipe and opening into the fire-pot and a channel or chamber Gr connecting the passage-way to the storage-reservoir and the ash-chamber, provided with a slide or valve at or near its union with the passage-way to the storage-reservoir, and a door below its union with the ash-chamber,

ber provided with an outlet or chimney at or near its upper end, a coking-chamber provided with an outlet at or near its upper end, a gas-reservoir connected by a pipe to the outlet from the coking-chamber, a slide'or damper between the outlet from the cokingchamber and the chimney and a channel or chamber connecting the outlet from the coking-chamber and the ash-chamber, said channel or chamber being provided with a slide or damper at its upper end and a door at or near its lower end substantially as described.

In testimony whereof we sign this specification in the presence of two witnesses.
