IMPROVEMENT IVN BASE-BURNING COOKING-STOVES.

Speciiication forming part of Letters Patent No. 122,156, dated December 26, 1871.

Specification describing a new and Improved Base-Burnin g Cooking-Stove, invented by WIL- LIAM CLARK, of Shelburne, in the county of Chittenden and State of Vermont.

Figure l represents a vertical transverse section of my improved cooking-stove, the line c c,

Fig. 2, indicating the plane of section. Fig. 2 is a vertical longitudinal section oi' the same on the line k k, Fig. l. Fig. 3 is a detail vertical section through the oven on the line c k, Fig. 2. Fig. 4 is a plan or top view of the stove, the oven andV reservoir being removed and the top plate partly broken away. Fig. 5 is a top view of the stove with the uncovered oven and reservoir in place. Fig. 6 is a detail horizontal section on the line q q, Fig. 2, of the tire-place. Fig. 7 is a detail front view of the door to the air-chamber under .the

v grate. Fig. 8 is a horizontal section of the same on the line kg, Fig. 7. Fig. 9 is a transverse section of the same on the line c q, Fig. 7. Similar letters of reference indicate corresponding parts.

This invention relates to a new cooking-stove, which is provided with a circular fire-place and rotary interior lining thereto, and witha feed` a removable cross-partition to have but halt` a supply of coal, which can be brought under either portion of the top plate or under the oven, as may be desired. The invention also consists in a new arrangement of draught'- door, grate, oven, and water-reservoir, all as hereinafter more fully described. A

A, in the drawing, represents the hearth-plate of the stove. Bis the outer case oi' the {ire-place,

made circular and enlarged at its upper part, as shown. C is the top-plate of the stove, placed upon the case or main body B, and provided with a suitable number of holesfor the reception of the cooking-vessels. D is an oven, placed back of the-iire-place, against the body' or case B, to receive the surplus heat radiated from the back of the same. The top plate C extends over the oven D, as shown in Figs. 2 and 4. E is the annular inner lining of the lire-place. It is made of metal,

of inverted truncated conical form, with a toothed lower edge. A pinion, a, mounted upon a crankarbor, b, which has its bearings'in the side of then case B, meshes into the toothed lower edge of this lining E, so that by turning the arbor b `the lining will also be revolved within the case B. The upper part of the case B, in which the lining E is contained, is made to bulge-out, as shown, so that thus an annular space, d, is formed between B. and E, said space being closed on top vand bottom. The lowerpart4 of the lining E rests on a shoulder, c, which is formed within B, while its upper edge lits a circular groove on the un- .der side of the top plate C, or is otherwise so made as to close the space d on top and bottom. F is the grate. It is of circular form, `made of radiating barsV that are connected by a central solid portion and by an outer ring, as in Fig. 4. From this grate projects downward a central pin or shaft, f, which has' a bottom arm, g, projecting.

forward toward the door .Gr in the lower part of the case B. The body of the grate rests with its .lower rim on a cross, h, which is `placed across the bottom of the `tire-place, the ends of the cross resting upon notches cut into the lining E. The pin f iitsloose through the cross h. The door G has an adjustable register, z', forregulating the admission of air to the fire, substantially like all similar doors in stoves. ture through the door for the reception of a bar or lever, which, when inserted within the socket g, can be used to shake the grate by oscillating it `horizontally onits pivot f. The aperture through the door G for receiving said bar for shaking must be of a certain length to permit 'the oscillating movements ofthe bar. In order to reduce thesize of this aperture and not make it too large an opening for air, Ihave provided in it a slid-` ing plate j, perforated just enough to admit the shakingar. This plate j rests on a track in the door, and slidesback and forth when the bar is vibrated. H is a transverse partition for the iireplace. It is placed across the lining E, its ends itting grooves of said lining. This partition divides the fire-place into halves, so that fire may be had only on one side. By'means of the arbor b the lining E can be turned to bring the fire under any part of the .top 'plate C, even under the oven I, which is placed upon the top plate G. The smoke escapes from the fire-place through a hole, l, in the lining into the space d, and thence There is also an aperthrough a hole, fm, in the back part of the ease B into a chamber, n, which is over the oven D, below the top plate G, as Vshown in Fig. 2. The

' smoke then must pass out forward (see Fig. 6)

and sweep entirely around the lining E before it can escape through the hole m,- but the liningE can atany time be turned to make the draught more direct. From the outer face of the lining E project ribs o o through the spa-eed against the case B,.while similar ribs, p p, project from the inner side of B toward E. Whenever the latter isturned the ribs will sweep the walls of the space d of all ashes that may have accumulated therein, and cause the same to escape through notches kcut through the supporting-flange or shoulder e. L is the ash-pau, of suitable kind, introduced through the door G. Behind the oven I is placed, upon the top plate C, the Water-reservoir J. The products of combustion pass 4ordinarily to the chamber u, betweenztwo vertical ribs r r therein, and then up between said ribs through a hole, s, into a flue, t, which is between the oven I and reservoir J. This iiue leads to a smoke-chamber, fu, above the oven, where the current is divided and spread by a transverse rib, y, to finally escape to the smolre-iiue c..

When, however, a damper, w, above the hole s is closed, the smoke passes backward between the ribs r r and around their back ends, and then forward again on the outer sides of said ribs, entering the flue t through the holes fr fr. way the heat can be carried under the reservoir J by closing, and away from the same by opening, the damper w. The top plate C is or ymay be perforated under the reservoir J to increase the effectiveness of the heat. Z is a short pipefor the escape of steam from the reservoir. M is a vertical cylinder for the supply of Vcoal tothe In this fireplace. It is fittedyupon vand through the top plate C in such position `that its charges will, in the ordinary position of E, fall forward of the partition H, the ordinary position being when the hole l is in front. a is a removable plate in the backV of the smoke- `hamber n, allowing the san'ie to be properly cleansed out.

,Having thusdescribed my invention, I claim as new and desire to secure by Letters Patentl. Awcookingstove provided with a circular case or body, B, which contains a circular rotary lining, as set forth. y

2. The rotary lining E, arranged Within the fire-place of a cookingstove and geared into an arbor, b, whereby it can be turned,.as set forth.

3. The grate F, supported and swiveled in the cross h, which is secured within the rotary lining E -of the stove, as specied.

4. The partition H, fitted across the circular fire-place, substantially as herein shown and described.

, 5. The combination of the rotary lining having the hole l, with the stationary 'ease B having the hole m, and with the intervening annular smokepassage d, as set forth. A

6. The ribs o p, arranged respectively on the lining E and case B, substantially as 'and for the purpose herein vshown and described.

7. The smolie-cha1nber n, under the reservoir J, when provided with the ribs r r, and arranged in combination with the damper zo and iiue t, substantiallyas herein shown and described.-

The above specification of my invention signed by me this 18th day of October, 1871.
