AIR-HEATER:

1&28964.

Specification of Letters Patent.

Patented May 28,1912.

Application filed September 8, 1910. Serial No. 581,061.

To all whom it may concern:

Be it known that I, ADoLrH SOI-ILUETER, a citizen of the United States, residing at Oakland, in the county of Alameda and State of California, have invented certain new and useful Improvements in Air-Heaters, of which the following is a specification.

This invention relates to heaters, and the principal object of the same is to provide a means whereby air can be supplied to the heater from the outside of the room so that the heated air will be fresh.

This invention is illustrated in the accompanying drawings, wherein,

Figure 1 is a perspective view of the improved heater, a portion of the heater being broken away to illustrate the interior construction. Fig. 2 is a vertical sectional View along the line A-A showing particularly the means for admitting fresh air to the heater. Fig. 3 is a view along the line BB looking down.

The upper portion of this heater may be of any desired type but, in the one illustrated, it consists of a series of cylindrical casings, 1, which are secured to a hollow base, 2. The base, 2, is provided with a bottom plate, 8, which closes the bottom, and thus prevents air in the room from entering the heater. Above the plate, 3, the heater is provided with a second plate, 4, which is provided with a number of apertures, 5, to permit air to pass from the chamber, 6, formed by the two plates, into the compartment, 7, above the plate, 5. A heating pipe, 8, is mounted within the chamber, 7, and is provided in its upper surface wit-h a series of openings, 9, through which the fuel escapes. The outer end of the pipe, 8, is connected with the source of fuel supply such, for instance, as a gas pipe. A gas mixing chamber, 10, is placed in the outer portion of the pipe to permit air to be mixed with the gas. An inlet pipe, 11, is

centrally located at one side of the heater, and communicates with the chamber, 6. A grating, 12, is placed within the wall, 13, of the room, and is provided with an extension, 14, in which the pipe, 11, is removably secured. The upper portions of the casings are'supplied with a number of openings, 15, through which the heated air passes out into the room.

In the operation the heater is placed in a room with the pipe, 11, in the extension, 1%, and the gas supply pipe secured to the outer end of the pipe, 8. The gas is now turned on and lighted at the openings, 9, thus creating a draft. After the gas is lighted the air passes in through the grating, 12, and into the chamber, 6. From here it passes up through the openings, 5, formed in the plate, 4, and into the chamber, 7, where it is heated by the heating pipe. The heated air now passes up through the casings, 1, and out through the openings, 15, into the room.

Having thus described my invention, what I claim as new is:

A stove comprising a hollow base having an inlet formed in one side portion and having a plurality of openings in its upper face, collars leading from the openings in the upper face of said base, a bottom plate re movably secured to said base, a perforated plate removably secured within said base and dividing said base into an upper and lower compartment, a heating pipe extending through said upper compartment, and a casing mounted upon said base and connected with said collars whereby heated air will pass from said upper compartment into said casing.

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

ADOLPH SCHLUETER.
