Letters Patent No. 94,593, dated September 7, 1869.

PARLOR-STO'V'E.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern:

Be itknown that I, J on): 1-1. Goonrnnnow, of Troy, in the county of Rensselaer, and State of New York, have invented a new and improved Parlor-Stove; and 1 do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the accompanying drawings, making a part of this specification, in which-- Figure 1 is a longitudinal vertical section;

l igure 2 is a transverse horizontal section; and

Figure 3 is a horizontal section'o f the body of the stove, taken on the lincly y, fig. 1.

This invention relates to the class of coal-stoves in which the is'consumed by the introduction of extern-a1 air; and

It consists in constructing the fire-pot of upper and lower hollow perfin'ated rings, with intermediate hol low perforated standards which form the sides of the firepot, leaving lateral openings between said standards for the escape of gases and smoke, into which currents of air are drawn from the said peribratious in the rings and standards, for the purpose of more thoroughly consuming said smoke and gases; also, in

mounting the said standards upon pivots, so that they I be discharged through said notches; also, in such a general arrangement of parts, in connection with the tire-pot, as shall effect the drawingoti' and consumption of smoke and gases, either from the top of the fire-pot or its bottom, or from both quarters at the same time.

In the drawings is shown a'parlor coal-stove, in which a is the ash-pit, and l), the flue surrounding the same, for the discharge of products of combustion into the escape-pipe b.

The lire-pot A rests on a plate, 0, supported on the top of the ash-pit, and havinga grate in its centre for the supply of air to the fire-pot, which supply is regulated by the apertures and damper in the door of the ash-pit. I

The fire-pot is constructed of two hollow rings, B B, one at the bottom and the other at the top, the

lower ring B being in communication with the exter-' nal air by means of a horizontal passage, the mouth of which is guarded by a damper, c.

The chamber within the ring B is connected with the chamber in the ring B, by means of the passages within the upright standards 0, which standards also serve to sustain the upper ring, and, moreover, form the sides of the fire-pot, being set around it in sulficient numbers.

The air that has free access to the interior of the rings and standards when the damper c is open, finds exit therefrom through perforations 0', so that as the smoke and gases pass between the standards on their wayout, they are permeated by a great number of fine jets of air, which supply oxygen to effect the more thorough consumption of the products of combustion.

In the sides of the stove, immediately opposite the standards 0, I also provide a suitable number of perforated plates, d, through which external air enters, and co-operates with the jets from the rings and standards in consuming the gases.

When anthracite coal is burning in the stove, as it evolves no smoke, the lateral spaces in the fire-pot need not be as large as when bituminous coal is used. Consequently, in order to vary the size of such spaces at pleasure, I make the standards 0 of greater width than thickness, and mount them on pivots, so that they maybe turned so as to presenteither their wider or narrower sides, at pleasure, to each other.

I provide a chamber, D, within the stove, outside the ash-pit, just below the level of the plate 0, and just above the flue b.

The chamber D opens into the flue, and the flue opens into the escape-pipe b, in which, near the point of junction, is a damper, b.

I also provide another chamber, E, fonned by the transverse partition 0, just above the fire-pot.

The chamber E also opens into the escape-pipe, in which, near the point of junction, is a damper, o".

By closing the damper e", the products of combustion are all turned downward into the chamber D, whence they pass off by the flue b. Ii, on the other hand, the flue b is closed by means of the damper b, the products of combustion rise into the chamber E, whence they pass off into the escape-pipe. By keeping both the upper and lower dampers partially closed, the products of combustion will pass off in two currents.

In order to effect the more thorough consumption of such products of combustion as rise, I employ the plate 0, to check the currents and turn them to the sides of the stove, where are made notches h h h in the plate, through which notches the smoke and gases ass.

p The air necessary for their combustion is supplied from perforated plates It, set in the sides of the stove I in close proximity to the notches h. One or more oi the plates h may be hinged, so as to serve as a door.

When the gas bums in contact with these perforated plates, it makes a considerable illumination. Hence, if found desirable, the perforated plates might be extended entirely around the stove, so as to increase the illumination.

The notches h in the plate e also serve as apertures for the passage of coal. The plate may be hinged, if desired, so as to be raised up to facilitate the introduction of coal. 1 design making the plate hollow, and have its cavity communicate'with the external air, so as to supply a sufliciency of oxygen to insure complete combustion.

Having thus described my invention,

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. The fire-pot, having a grate in its bottom, through whichair is admitted to support the combustion 'in the lower part of the fire-pot, and with lateral openings through the fire-pot, just above the grate, and in communication with the smoke or draught-pipe, (for burning and discharging the gases at the lower part of the fire-pot) in combination with the chamber arranged above the fire-pot, supplied with air, and in communication with the smoke or draught-pipe for burning and discharging the otherwise accumulating gases from the top of the fire-pot, all substantially as shown.

2. In combination with the above, the damper, for regulating and controlling the supply of air to the chamber or ash-pit under the grate in the bottom of the fire-box.

- through the lower part of the fire-pot.

4. In combination with the subject of the first claim, that damper in the sinoke-pipe which regulates and controls the escape of the gases of combustion from the lower part of the fire-pot, without altering or controlling the discharge of the gases from the combustion-chamberabove the fire-pot.

The upper and lower hollow rings and intermediate perforated standards, which together form the lower part of the fire-pot, and which have communication with the air outside of the stove, and with the lower part of interior of the fire-pot, or the passages through which the burning gases escape laterally from the lower part of the fire-pot.

6. The dampered-aperture, by which the admission of air to the hollow rings and perforated standards of the lower part of the tire-pot is controlled and regu lated, in combination with the grate in the bottom of the lire-pot, and the air-chamber under the grate, to which the admission of air is regulated and controlled by a separate dainpered-aperture, all substantially as shown.

7. In combination with the perforated door or illuminating-casing, of the fire-chamber over the fire-pot, having passages for the gases to burn along or opposite to the perforations in the casing.

8. The plate 0, provided with the notches h, as and for the purpose specified.
