METHOD OF COMBINING ELEVATED OVENS WITH COOKING-STOVES SO AS TO RENDER THE SAME MOVABLE.

Specification of Letters Patent No. 2,404, dated December 30, 1841.

To all whom it may concern Be it known that I, ELI O. ROBINSON, of the city of Troy, in the county of Rensselaer and State of New York, have invented a new and useful Improvement in Stoves; and I do hereby declare that the following is a full and exact description.

The principle of my improvement consists in providing a movable oven to a stationary stove, so constructed as to allow the fire and heated air to pass through the lines of the oven in whatever position, within the limits prescribed for its movement, it is placed, and then through a stationary stove pipe to the chimney.

An oven, stove and pipe of this description, with their appendages, are represented in Figure I, of the annexed drawings, in which A is the stationary part of the stove, B a circular movable top to the same.

O, O are pipes supporting the oven D and serving as fines or passages for conducting the fire and heated air into its fiues, for which purpose the pipes are placed over openings provided for them in the top plate of the stove, each being supplied with a common collar for the purpose at E, E. The

top of the same pipes are connected with the oven at F, F, when like openings and collars are provided for them in its outside plate. The entire circle of the oven is formed with double plates, and the space between them constitutes its flues or passage for the circulation of the fire, &c., around the inner or baking apartment.

G is a stationary collar over which a common stove pipe is placed for conducting the smoke to the chimney.

H is a horizontal plate of sufiicient width and thickness to support the collar which is attached to it and both plate and collar with the stove pipe are supported by the upright standards connected with the plate at I, I, and with a rim of the permanent part of the stove at J, J Or instead of two standards I sometimes make use of one only, in which case the horizontal plate H is extended as an arm from the top of the standard to the collar G and is made to terminate on the opposite side of it, the collar being attached thereto at or near its extremity and over the center of the oven, the same as when two standards are used. I attach the foot of each standard in either case to the rim in the manner represented in the drawing or by a dovetailed joint or any other common mode of fastening at my option. A collar is also attached to the center of the top of the oven as partially seen at K and extends up within the collar G so as to form the connecting passage from the flue of the oven to the stove pipe. These two collars are apportioned in size so as to allow the inner one, or that connected with the oven to turn easily within the other which serves to preserve its own central position. With these provisions and a central pin from the stove through a small opening in the rotary top as shown at L, the oven with the rotary top is made movable horizontally as upon its center, by means of which I am enabled to place one end or the other of the oven directly over the fire place or furnace of the stove or at any relative distance therefrom within the circle of its movement, and also, by aid of a common damper with which each of the supporting pipes is provided, as shown by their handles at M, M the passage through either may be opened and the other closed, by means of which the heating proc ess of the oven is equalized or varied at discretion.

Another modification of the principles of my improvement is represented in Fig. II. In this the stove N and collar O for a common stove pipe, are in like manner stationary, and the latter like the other is sup ported by a horizontal plate to which it is attached at O, the same being of a width and thickness sufiicient for the purpose and both likewise sustained in their position by the upright standards P, P, (or by one instead of two at my option) which at the top are connected with the plate and at the bottom with the permanent part of the stove as represented in the drawing being united therewith by any common mode of fastening, while the oven Q, having its end plates extended down so as to rest in the grooves in the top plate of the stove shown at U, U is made movable back and forth from front to rear by being shoved one way or the other by hand or otherwise, the grooves and plates serving to guide it in its direction when thus moved. In the drawing it is represented at its rear station leaving the boiler seats R, R free for ordinary use, the fine of the stove, as shown in the drawing, being sufficiently extended for that purpose.

The baking apartment of the oven, suspended in the usual manner by flanges or other projections from the inner surface of the end plates of the oven, is, except the end, surrounded by a flue or open passage for the circulation of the fire and heated air from the stove which is introduced through an opening in its top plate as shown in a sectional view of the plate at S and partially seen at S, Fig. II. This opening is so located as to come under the front ascending flue of the oven when at its rear station as there represented, and under its back flue t,.when brought forward over the fire place. hen in this front station the boiler openings, being then under the oven, are left covered or uncovered by their lids as the state of the fire or temperature of the oven may require.

By means of a common sliding damper upon the top of the inside or baking apartment of the oven, either the front or back flue may be closed and the fire, &c., made to pass exclusively through the other. The handle for moving the damper is seen at T.

In order to eflect a smok passage from the fines of the even, when either at its front or rear-,station, to the stationary stove pipe, I provide two openings in the top plate of the oven, as shown in the separate view thereof at V, Vmaking the distance between them equal to the extent of its back and forward movement, so that at the termination of each movement one of these openings will be left exactly in the place which the other previously occupied, or which is the same thing directly under the stationary collar for the stove pipe and in order to make good the communication between the opening thus brought under the collar and the stove pipe, and at the same time close the other opening, a sliding plate is provided with two openings of corresponding dimensions as represented at W, and in a separate view of the plate at X, and placed upon the top of the oven, so as to be movable thereupon in the direction of its length either way. From the upper surface of this plate a flange is raised, extending in an oblique direction nearly across it as shown at Y, and a corresponding groove or double flange from the under side of the plate to which the stationary collar is attached, as seen at 2, 2, so as to interlap with the flange of the sliding plate; by means of which, as the oven is moved from one station to the other, the sliding plate is borne in this lengthwise direction of the oven one way or the other as by an inclined. plane according to the start given to these flanges, and I fix the angle of their inclination and the relative position of the two openings in the plate so that one of them will be brought exactly over each of the openings in the top plate of the even as it arrives under the collar for the stove pipe, While the same lateral movement of the slide carries its other opening on one side of that on the same side of the top of the oven and closes it with the plate of the slide. In this way, without further attention, the sliding plate serves as a damper to each passage. By means of a loose collar, as shown at a, placed upon the sliding plate as at I), so as to extend up within the stationary collar 0, by which it is kept in its place, either of the openings are covered by the loose collar when brought under it by the movement of the plate in the manner already described, and thus the passage from the flues of the oven to the stove pipe is perfected. The lateral movement of the slide is preserved by means of a lip or flange at its back and forward edges, made to overlap the edges of the top plate of the oven as shown in the drawings.

lVhat I claim and desire to secure by Let ters Patent isl. The mode of adapting an elevated oven to a rotary top of a stove or combining the same therewith so as to allow of the oven revolving with the said top by means of the stationary collar G combined with the oven and with the stationary part of the stove substantially in the manner above set forth.

2. And I also claim the method of combining the discharge openings V, V of the movable oven represented in Fig. II of the annexed drawings with the static-nary collar or smoke pipe 0 by means of the sliding plate W in the same figure having an oblique flange adapted to a groove in the underside of the plate supporting the stationary collar and provided with apertures corresponding to the openings V, V, in the oven top by means of which arrangement the connect-ion of the movable oven with the smoke pipe is maintained, all as above set forth.

Subscribed this 9th day of December 1841 before us.
