HEATING STOVE.

HEATING-STOVE.

SPECIFICATION forming part of Letters Patent No. 372,620, dated November 1, 1887.

Application filed February 3, 1887. Serial No. 226,437.

To all whom, it may concern:

Be it known that I, ROZANDER S. HIGGINS, a citizen of the United States, residing at Neoga. in the county of Cumberland and State of Illinois, have invented an Improvement in Heating- Stoves, of which the following is a specification.

My invention relates to central air-tube heatingstoves, and particularly relates to those stoves in which the central air-tube is fed with air entering it through horizontal pipes extending from opposite sides of the stove.

My improvement consists in the construction hereinafter described, and pointed out in the claims.

In order that my invention may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which- Figure I is a front elevation of my improved heating-stove. Fig. II is a vertical section thereof.

The base of my stove may consist of a lower plate, 1, upper plate, 2, side plates, 3, rear plate, 4, and front plates, 5, forming a tight ash-pit.

7 are plates for supporting the ashtray 6 on the bottom plate. Supported on the upper plate, 2, is the fuelpot or lower portion, 8, of the fire-chamber, having a rotary grate, 9, operated by ashaker, 10.

11 is the flaring upper portion of the firechamber. Surrounding the fire-chamber, and also supported on the upper plate, 2, is a shell, 12, forming a still-air chamber, 13. Above the fire-chamber are the lower and upper sections, 14 15, of the combustion-chamher, surmounted by a cap-piece, 16, provided with a smoke-pipe, 17, having a damper, 17.

The above-described parts may be of any approved construction.

18 is the central airtube extending from a point beneath the grate through the fuel-pot or lower portion of the fire-chamber; but instead of passing upward through the combustion-chamber,as usual,it connects with an upper horizontal tube, 19, forming branches extending toward opposite sides of the stove through the lower part of the upper portion,

(No model.)

11, of the fire-chamber into the still-air chamber, where they connect, respectively, with downwardly-projecting tubes, 20, extending beneath the grate. The central air-tube is supplied with fresh or outside air by means of a lower horizontal tube, 21, extending through opposite sides of the base beneath the lower ends of the tubes 20,and connected by a neck, 22, with the central air-tube.

23 is the stove-door.

It will be observed that instead of using the central air-tube, as heretofore, for room-heating purposes, it is employed for heating the air for feeding hot air to the fuel in the direction indicated by the arrows in Fig. 2.

The outlets to the air-tube are at a higher elevation than the inlets, so as to be in close proximity to the grate.

The position of the horizontal base tube is such as to receive considerable heat from the fuel.

The construction of the base is such that all air for the tire enters the ash-pit through the tubes; but should it be desired to increase the draft this is readily accomplished by partly drawing out the ash-tray.

24 are dampers in the outer ends of the horizontal base-tube, by which the air-feed is regulated, the damper 17 regulating the draft through the smoke-pipe. Thus the fire can be made to burn fast or slow, as required.

Having thus described my invention, the following is what I claim as new therein and desireto secure by Letters Patent:

1. An air-feeding device for heating-stoves, consisting of the lower horizontal tube, up per horizontal tube having tubes at the ends thereof projecting downward, and the central tube connecting the horizontal tubes, substantially as described.

2. The combination, with a heatingstovc, of the vertical central air-tube passing-through the fuel-pot, the lower horizontal tube by which the central tube is fed, passing through the side of the stove, and the upper horizontal tube passing through the fuel-pot, provided with tubes at its ends projecting downward into the ash-pit, substantially as described.

3. The combination of the base, the firechamber, the shell surrounding the fire-chambar on the base, forming the still-air chamconnecting the upper horizontal tube with the her, the horizontal tube extending through ash-pit,-substantially as described.'
