' LO ALL WHO IT MAY CONCERN:

Beit known that I, WARREN P. MIBLER, of the city and county of San Francisco, and State of California have invented a new and improvedMode ofonsti-ucting Fire-Places, by the use of which a large .saving of' fuel is effected; and I do hereby declare that the following is a full, clear, and exact description oi' the construction and operation of the same, reference being` had to the annexed drawings, making a part of this specification, in irhichi Figure No. I is a perspective View of a fireplace, `Vith la portion of the back and jamb broken away, thus exposing to view the air passages indicated by the arrows. A i

Figure No. 2 is a longitudinal sect-ion of fire-place and c oldair duets, hot and dead-air chambers, brickwork, Sic. i

Figure No. 3 is a vertical transverse section, showing the het and cold-air`dncts, dead-nir chamber, divisions in the heating-chamber, smoke-Hue, grate, &c. i

Like letters refer to like parts on the several dramfinggrs.` i

Letters a a are cold-air ducts; letters b b are hot-air duets; c e c c ehamberfwhere the air is heated; dd deadair chamber; ee cast-iron back and jamb; fff ledges, cast on the back andjanibs to divide the hot-air chamber into; compartments, but which are connected by small passages, as shown at l l; g a smooth,` bright metallic partition, dividing the hot from the dead-air chamber; 7L ha recess in the hack, filled with soap-stone or {ircbricks; ihre-grate; smoke-flue: lc /c c brick-Work.

lo enable others skilled in the art to make and usc my invention, I will proceed to describe its construction and operation` I construct an iron-fire-place of the proper form, with a recess' in the back where exposed to the greatest` heat, the saine to be filled with soap-stone 0r brick. Ledges arecast` upon the back and jambs, so as to form the same into air passages, in connection witn the partition g g, which forms the outside oi' the hot-air chamber, said partition being made of bright., smooth iron for the purpose of reflecting back or coniining the heat in the chamber, so as to bez-conducted, intotbe room through the ducts b b. The space in the brick-work is made sufficiently large, so that when the fireplace is set, there will remain an'air chamber all around the metal back g g, as shown at al d. It will be readily understood that when the airthat fills the chamber e becomes heated by being in Contact with the fire-place e e, it willi be forced out through the ducts b b by means of the cold air entering through the ducts a a. Thus it will be seen that a constant supply of hot air will be discharged into the roomv aslong as the fire is kept up in the grate.

Double {ire-places have been made in various ways, of materials such as brick, soap-stone, a'nd iron. 'All such I do not claim.

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

1. A lining or partition, g, made of a suitable reflecting metal, and located within an air-heating-chamber, behind the fire-place or chamber, and separating the latter from the dead-air chamber, substantially as and for the purpose specified.

2. In combination with the partitioirg, I claim theair-heating chamber ccc, and dead-air or nou-conducting chamber d, all constructed and arranged in the manner and for the purpose specified.
