SPECIFICATION forming part of Letters PatentNo. 710,053, dated september'eo, 1902.

Application filed July 2 3. 1901.

' Be it known that I, MATTHEW GaiswoLD, Jr., a citizen of the United States, residing at Erie, in the county of Eriet-and State of Pennsylvania, haveinvented certain new and useful Improvements in Gas-Stoves; and I do hereby declare the following to bea full, clear, and exact ,description of the invention, suoli as will enable others skilled in the art to whichv it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked.

thereon, forming part of this specification.

Myuinvention relates to improvements in gas-stoves; and it consists substantially in making the stove with acent ral air-line which extends up through the lire-box of the stove and opens into a heating-chamber provided with a bathe-plate or dellector and a central air-Hue above the heating-cham bersurrounded by asmoke-flue. These and other features of my invention are hereinafter set forth, and

illustrated in the accompanying drawings, in'

which- Figure l shows a vertical central section of my improved gas-stove. Fig. 2 shows anti-ansverse section of the same on the line @c @o in Fig. l.

In the drawings thus illustrating my invention, Ais1 he base of the stove, supported upon legs A in the usual manner. The central part of the base A is cut away, and to'inwardlyprojecting lugs-ft I secure a circular gasburner B, provided with peripheral lugs b, adapted to be bolted to' the lugs d on the base arms b'. Upon the periphery of the base A I place thelire-box C, and to the lugs b on .the burnerl'I secure the lower end of anV air-flue D, and in the lower partof the reboxC, I place a basket-grate E, 'which is supported by means-of lugs e, extending to 'and contacting with the corners c of the fire-box shell C', and lugs d on the lower portion of the air-flue D.- Upon the top 'of the air-fine D, I secure a heating-chamberfF, the lower half F thereof resting upon the .top of` the air-ue D and the upper hali` thereof, F2, resting in a groove'f in the periphery of the lower semi No. 69,345. in@ model.)

hall' F' of the heating-cham ber F, and between the two halves of the heating-chamber F there is secured a baflie-plate G by means of peripheral lugs g thereon entering slots between thet wo halves F and F2 of the heating-chamber F, so that with the exception of the space occupied by the lugs g thereon there is a continuous peripheralopening around the edge of thebafle-plate G for the passage of air upward from the lower part of the heatingchamber. It will also be observed that by means of this Construction the heating-chamber is entirely supported upon the air-flue D and a clear space left entirely around it between its periphery and the inside of the shell G of the {ire-box C for the escape of the products of combustion from the fire-box C. Upon the top F2 of the heating-chamber F, I place an air-flue H, which connects with the heating-chamber by means of a central openingf through the top F2 of the heating-chamber- This air-flue H extends up to the stove-top I and discharges the heated air therefrom through openings `1l therein. On the top of the fire-box C', I place a smoke-flue J, which extends up to the stove-top I and entirely surrounds the air-flue H, so as to leave a narrow annular spa-ce K between said outer ue J and the inner air-fine H, through which the smoke and products of combustion pass up around the heating-chamber F and pass lto a pipe-thimble L on one sideof the upper part of the flue J. In thisconstruction it will be observed that I utilize the heat both to heat air passing up through the central flue, rbut also utilize itfor direct radiationvto the greatestextent possible.

Having thus described my-inventiomso as to enable others to construct and use the same, what I claim as new, and desire to secure by Letters Patentof theUnited States, is-

In a gas-stove, the combination 0f a. base, aV

chamber resting upon and supported by said flue so as to leave an annular space between it and the shell of the lire-box, a baille-plate in said heating-chamber having an annular opening around its periphery, an air-flue on the top of said heating-chamber discharging through openings in the Istove-top, and a smoke-Hue resting upon the top of the `hell 0f the fire-box and surrounding:r the air-flue above the heating-chamber, substantially as set forth. m

In testimony whereof I aiix my signature in presence of two witnesses.
