Letters Patent No. 99,264, dated January 25, 1870.

CO OKIING-STOVE.

I The Schedule referred to in these Letters Patent and making part of the same To all whom it may concern Be it known that I, CHARLES VAN De MARK, of Phelps, in the county of Ontario, and State of New York, have invented an Improved Cooking-Stove; and I do hereby declare that the following is a full and exact description thereof, reference being had to .the accompanying drawings, making part of this specifica- Figure 1 being a top view of a cooking-stove, provided with my improvements.

Figure 2, a top view of the same, with the top-plat removed, and the flanges of the damper-rings in horizontal section.

' Figure 3, a transverse vertical section thereof, in a plane indicated by the line 'x-z, figs. 1 and 2.

Figure 4, a longitudinal vertical section of the same, in a plane indicated by the line y y, figs. 1 and 2.

Figures 5 and 6, bottom and side views respectively of a part detached.

Figure 7, a bottom view of parts detached. Figure 8, a central vertical section of a part detached. Like letters designate corresponding parts in all of the figures.

The first feature of my invention consists in damperrings, inserted .in the boiler-holes of the stove, so that they receive the boilers and other stove-furniture as in the ordinary boiler-holes, the valves or dampers thereof being formed by concentric flanges, which project from their lower-surfaces downward across the fluesspace under the top-plateof the stove, over the oveu, aud.being arranged respectively in connection with division-plates and damper or valve-apertures, so that by simply turning the damper-rings, as required, the passage of thedraught may be closed, or partially closed, or directed in any manner desired, through the stove.

The second feature of my invention consists in additional and peculiarly-arranged stove-fines, as hereinafter specified; and

Another feature of my invention consists in a pecu liar construction of damper-rings, in connection with a specially-constructed boiler or heater, as hereinafter set forth.

The damper-rings A A are applied to any or all of the boiler-holes, in which they simply fit, like an ordinary enlargement-ring used with some cooking-stoves. Thesedamper-rings may be quite narrow, and they are closed by the .usual covers.

Their damper or Valve-flanges a a project downward in the arc of a concentric circle, as represented in figs. 5 and 6, the depth beingsnfiicient to reach across the flue-space B over the oven, and their 'width great enough to cover the damper-space or spaces, which they are intended to close. The rings are simply turned in the holes of the stove to open and close the damper-spaces, and this can be done while boilers or other'utensils are resting in them. Suitable marks may be formed on them, and on the adjacent stoveplates, to indicate their proper posit-ions.

The damper-rings of the front boiler-holes are arranged in connection with a partition-plate or plates,.

0, the damper-flanges closing damper-apertures c c therein, as shown in fig. 2, where the right-hand aperture is represented as open, and theleft-hand aperture as closed by the damper-flange. By this front damper arrangement the draught can be conducted back over the oven, either through one of the apertures c 0, so

as to concentrate theheat' under the utensil in that damper-ring, or through both apertures c c. simultane-' ously, whether they are entirely open' or partly closed,

or whether one is closed more than the other; or both apertures may be entirely closed, so as to stop all draught over the oven.

The damper-rings of the back boiler-holes are employed in connection with another transverse partitionplate or plates, D, the damper-flanges closing apertures d d therein, in the same manner as the apertures c c, in the front division-plate, arecontrolled by the front damper-rings. I

These back apertures d d admit the draught immediately to the stove-pipe opening F, when a pipedamper, j; therein is turned back, as shown in' fig. 2;-

The arrows show the direction of the draught.

A modification is shown at the left-hand back boilerhole in fig. 2, where the concentric dam'pera is represented as separate from the ring; but this is neither s0 cheap, nor simple, nor convenient as if joined to the ring itself. l

These damper-rings may be vapplied to an ordinary stove, if furniture of smaller size is used, to fit the somewhat smaller boiler-holes in the rings, by insert ing suitable-division-plates, with apertures to colre spend with the dampers, in said stove; But my improved arraugement of stove-fines, in connection with these damper-rings, gives additional efiiciency thereto.

First, there are side-fines H H above the oven, andoutside of the usual flue-space B over the oven, and alsoa back-fiue, I, above the oven and behind the rear diving-fines K K of the stove, the fines H H opening into the flue I, and the latter into the stovepipe opening F, when the pipe-damper f is-tu-rned forward, as shown by dotted lines in fig. 2.

There are apertures g 9 into the side-fines H H, direct from the fire-chamber, and these apertures are closed, or not, by the damper-flanges of the frontdamper-rings, made wide enough, as shown in fig. 2, for the purpose, in addition to their regular duty to close the apertures c c.

There are also apertures h it, through the side di-j A vision-plates G G, from the flue-space B, over the flue, M,- between the front of the oven and the ashpit andfire-chamber, and a second flue, N, over the oven, between the same and the ordinary flue-space B.

This flue N communicates with the side-Hues H H, by apertures i i in the side division-plates, as shown in figs. 3 and 4. It may extend over the whole oven,

or only over the forward part of it, so as to afford sufficient space flues H H.

The uses of these various fines are as follows:

If it is desired to concentrate the heat of the fire under one or both of the hunt boiler-holes, both the damper-apertures c c are closed by the damper-rings, and one or both of the apertures g 9 opened, the pipedamper f being turned forward. Thus, the draught will pass directly away through the flues H H and I' to the stove-pipe. Or, if the heat is to pass through the'flue-space B over the oven, and be concentrated under one of the boiler-holes in front, and one at the back, the apertures g g and h h, and one each of the apertures stand (1 d are closed, the pipe-damper being thrown-back. Then the course of the draught will be as represented by arrows in fig. 2. Or, if all the boiler-holes are to receive equal heat, and the for the exit of the draught to the sidedraught pas'sed' directly to the stove-pipe, all of the apertures c c and d (I are to be opened, the side apertures g g and h h all closed, and the pipe-damper f thrown back. Or, if it is desired to send the draught through the flue-space B into the side-fines H H and back-line I, the apertures d d and g g are closed, the apertures a sand h h opened, and the pipe-damper f thrown forward. Or, if it is desired to turn the draught around the oven, the side-apertures g g and h h are closed, the apertures c c and 01 pi pe-damper f turned forward. The draught will then pass back through the flue-space 13, down the divingtlues K K back of the oven, forward through the flue L under the oven, up through the flue M in front of the oven, back through the flue N immediately over the oven, thence out, through the apertures 'i i, into the flues H H, and finally into the flue I and to the d are opened, and the I cent notch or aperture, 1), outsideof the damper-flange.

'lh'e boiler or heater is set into the ring, so that its partition-plate at will rest between the two adjacent apertures 02. 1), being held in position by'a notch, or projections, r.

Now, when the damper-ring is so placed that the aperture 1) is opposite to an aperture, 0, (as in fig. 1,) or d, and the other exit-passages for the draught closed, or partly closed, the draught will ascend through the inner aperture or notch n in the ring 0, and then, being prevented from passing direct by the partition m, it passes around the boiler or heater, and-finally down, through the aperture or notch 1), outside of the ring. By this means an intense heat is concentrated around the boiler, as when it is required to heat water rapidly, or around a heater, when, for instance, smoothing-irons are to be heated.

The platebetween the flue M, in front of the oven It, and the fire-chamber Q, and ash-chamber S, is inclined forward, so as to slide the ashes directly forward into the ash-pit I, under the hearth.

What I claiui as my invention, and desire to secure by Letters Patent, is-

The damper-rings A A, with concentric damperflanges a a,-substantially as and for the purpose herein specified;

Also, the side and rear flue's H H and I, arranged substantially as and for the purpose herein set forth.

Also, the flue M, in front of, and the flue N immediately over the oven, in combination with the fiues H H and I, and with the back, diving,-and bottomflues K K and L, substantially as herein specified.

Also, the construction of the damper-ring O, in combination with-the boiler or heater P, as herein described.
