A UNITED STATES I PATENT OFFICE.

sTovE.
SPECIFICATION forming part of Letters Patent No. 236,961, dated January 25, 1881.
Application filed October 11, 1880.
To all whom it may concern:
Be it known that I, SEWARD SHEPARD, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have in vented certain new and useful Improvements in Stoves; and I do hereby 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 appertains' to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.
The present invention relates to that class of heating-stoves which are provided with devices for mingling air with the smoke and products of combustion for the purpose of consuming the same.
The invention consists, mainly, in the combination, with the fire-pot or combustion-chamber of a heating-stove or furnace, of a coneshaped cover or top, which will serve to hold rarefied air over the fuelbed, so that the products of combustion will mingle with the same and be consumed at orifices formed at the top of the cone. A register-ring having apertures is used in connection with the orifices in the cone, so that by adjusting said ring through the medium of a rack and pinion, or equivalent devices, the size of the orifices in the cone can be increased or diminished.
The invention also consists in the combination, with the cone-shaped or dished cover, of a collar or plate, which is, at a suitable point above the orifices in said cover, attached to and carried by the fuel-magazine, and serves to prevent the heat from getting directly at the magazine and its contents.
In the drawings, Figure 1 shows my smokeburning attachment applied to a fire-pot and magazine-chamber of a stove. Fig. 2 is a plan or top view of my attachment.
The letter A designates a cone-shaped or dished plate, which is attached to the top of the fuel-pot or fire-chamber B in such manner that a chamber is formed above said fire-pot for the purpose of holding airadmitted through openings 0, near the top rim of the fire-pot. The air admitted in this manner becomes rarefied or heated in the aforesaid chamber, and
(No model.)
or products of combustion in general. At the top of the cone-shaped cover are formed a series of orifices or apertures, D, arranged in the form of a zone or circle, and having combined therewith an apertured register-rin g, E, which is capable of being adjusted for the purpose of varying the size of the openings in the cone A. These openings are for the egress of the unconsumed gases or products of combustion into the space or chamber formed by the outer casing of the stove and the magazine. A suitablepipe communicating with said chamber conveys the products of combustion into the chimney.
It will be perceived that the ascending products of combustion unite with the rarefied air present in the chamber 0, and are burned or consumed at the orifices D at the apex of the cone-shaped cover. There will, of course, be an upward draft through said orifices to promote the burning of the products of combustion, the air entering the openings in the fire-pot in the manner already mentioned.
The apertured register-ring E, fitted upon the portion of the cone provided with the open ings D, is adjusted through the medium of a short rack, G, and a pinion, H, carried by a shaft, 1 This shaft is journaled in suitable hearings on the cone A, and extends through the outer casing of the stove, where it terminates in a knob or disk, J, for the purpose of turning the pinion-shaft and giving motion to the register-ring thereby. A large opening, closed by means of a curved sliding plate, K, is also made in the cone-shaped cover A for communication with the fire-bed, in order to enable the same to be stirred by a poker, and also for gaining access to the bottom of the fuel-magazine. The slide K is fitted in guide-flanges on the cone A, and is provided with a suitable handle for moving the same.
The upper end of the cone-shaped cover A encircles the fuel-magazine near the lower end thereof, and the lower rim of the cone-shaped cover is adjusted so as to be in contact with the upper edge of the fire-pot.
To the fuel-magazine, at a proper distance above the orifices in the cone A, is rigidly secured a collar or broad flange, L. The object of this collar is to prevent the heat passing mingles with the ascendin' g smoke and gases through the orifices in the cone from coming in direct contact with the magazine, and thereby prevent the possible ignition of the coal therein.
1am aware that it is not broadly new to combine air-supplying devices with stoves for the purpose of consuming smoke, these de vices being generally located at the top of the fire-chamber. The construction presented by me, however, possesses decided advantages over all other devices designed for a similar purpose, it being more simple in construction, affording a means of a more complete combustion of the gaseous products of combustion than can be had by means of any other known device, and being capable of attachment to ordinary stoves.
It will be observed that the combustion of the gases and smoke takes place in a flaring chamber or space formed by the cone-shaped cover, the fuel-magazine, and the fire-pot, this result being due to the fact that said chamber contains a stratum of rarefied air, and is provided with apertures for the egress of the unconsumed gases. When the ring E is turned so as to cause its openings to register with the openings in the cone-shaped cover a most vigorous combustion or upward draft is the result, and this combustion or draft can be varied by adjusting the ring E. For retarding the combustion of the fuel-as, for example, when the stove is left unattended over nightthe ring is turned so as to close the openings in the cone-shaped cover.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1 The cone-shaped or dished cover having a series oftop openings, and means, substantially as shown, for varying the size of and closing said openings, in combination with the firepot, provided with air-inlet openings, and attached to the base of the cone'shaped cover, and the fuel-magazine attached to the top of said cover, as and for the purpose herein set forth.
2. The combination of the cone-shaped or dished cover A, having top orifices, D, adjustable apertured register-ring E, lower opening, and sliding door or plate, K, with the fire-pot and outer casing of a stove, substantially as and for the purpose set forth.
3. The combination of the cone-shaped cover A, having top orifices. the collar or deflecting plate L, the fuel-magazine, and the fire-pot, as and for the purpose set forth.
In testimony whereof I aflix my signature in presence of two witnesses.
SEWARD SHEPARD.
