Construction of Fire Boxes for Stoves.
Patented Oct. 25, 1859.
UNITED STATES PATENT OEETeE.
M. C. ORONK, OF AUBURN, NEV YORK, ASSIGNOR TO HIMSELF, IYM. BOYN- TON, JR, AND ALBERT II. GOSS, OF SAME PLACE.
IMPROVED MODE O F FEEDING IN FUEL TO THE FIRE-BOXES 0F COOKING-STOVES.
Specification forming part of Letters Patent No. 25,930, dated October 25, 1859.
To all whom, it may concern.-
Beit known that I, M. O. ORONK, of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in the Manner of Feeding in Fuel to the Fire-Boxes of Cooking-Stoves, &c.; and I do hereby declare that the following is a full, clear, and exact description of the con struction and operation of the same, reference being had to the accompanying drawings, in which Figure 1 represents a perspective view of the front part of a stove, being represented as broken off toward the rear. Fig. 2 represents a longitudinal vertical section through the same. Fig. 3 represents a vertical cross-section through the same. Fig.4 represents the same section as Fig. 3, showing the movable parts within as thrown in a different position from Fig.
The nature of my invention relates to the manner of adjusting the position of the burning coal nearer to or farther from the boilers or kettles to be heated; and it further relates to the manner of feeding the coal to the stove, so as to bring the fresh coal below the burning for the purpose of preventing the gases of said coal from escaping unburned.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
A represents the side plates of a stove.
B represents the bottom plate, and C represents the front doors.
D is the upperand stationary portion of the fire-box.
E is the lower and movable portion of the same.
G are two arms which extend from the ends of the movable box E down to near the bottom plate B, where their circular ends are supported by and play on the lugs a of the side plates A, which thus serve as the bearings for said movable box to turn on.
H represents the grate of the fire-box. It fits within the movable box IE, and has projeetionsb formed on its ends, which fit in the guide-grooves c, and by means of which the grate is retained in its position while moved within the fire-box E.
d are pins or pivots on the ends of the grate II, which pass through the slots f of the box E.
I represents a shaft which has its bearings in the arms G, and to which two slotted cams g are secured, one at each end of the fire-box. The pivots (Z pass through curved slots of the cams g, and they and consequently the grate H are operated upon when the cams are turned by means of the shaft I. The end of the shaft I passes through a circular slot 72, in one of the sides A, and is provided with a handle, K, by which said shaft can be turned on its axis as well as it can be moved in the slot 71 thereby causing the fire-box E to turn on its bearings.
The shape of the fire-doors is convex, so that when they are closed a space maybe left between said doors and the fire-box, the lower edges of the doors fitting tightly against the curved edge of the bottom plate B, while the upper edge is formed with a horizontal flange L, which fits tightly against the front plate of the stove when the doors are closed. m represents holes through the fiange L, by which the air which keeps or aids to keep up the combustion is admitted to the stove. n are similar holes, and for the same purpose, in the side plates A, which communicate with the space which is between the sides A and the ends of the fire-box. The air which enters through the holes on and n passes in the direction indicated by the arrows around the ends of the fire-box before it enters the fire through the grate II, thereby cooling the outside plates and preventing the same from becoming overheated, and dispensing with the use of brick lining.
The shape of the fire-box E is represented in cross-section in Figs. 3 and 4E. The upper part of the same is circular, so that when it is turned on its fulcrum it may .remain in contact with the lower edges of the stationary fire-box D. It also extends to the rear in a circular flange 0, which, when the box E is thrown forward, as represented in Fig. 4, will close up the stationary fire-box D, for the purposes hereinafter described.
The operation of this stove is as follows: The coal being in the stove, as represented by X in Fig. 3, the draft from outside the stove passes through the holes m and n in the direction of the arrows, and prevents the outside of the fire-box from becoming overheated, as above described. hen fresh coal is to be added to the lire, the shaft I is turned by means of the handle K, and the cams 9 turning with it cause the grate II to rise by reason of the pins (1 being acted upon by said cams. The shaft 1 is thus turned until the upper and circular face of the grate H shall be flush with the upper edges of the movable firebox E, as represented in red in Fig. 3, and consequently all the burning coal shall be raised into the stationary fire-box D. The shaft 1 is now moved in the slot It so as to turn the arms G and consequently the firebox E on theirbearings and into the position represented in Fig. 4, so that the burning coal may now rest on the flange 0, and when in that position the shaft I is turned again on its axis, and the grate His lowered to the position represented in Fig. 4. In this position the coal is thrown onto the grate II, and when the desired quantity has been put into said box it is returned to the position represented in Fig. 3, when all the fresh coal will be below the burning coal, and thus the gases arising from the fresh coal will be ignited without loss.
The construction of the camsg is such that the grate II may be raised and lowered with the greatest facility, and also that it may be retained by it in any desired position. This construction, too, very much facilitates the separation of the ashes from the burning coal by moving the handle K quickly, and the grate H may be set in a higher or lower position, thus bringing the fire nearer to or farther from the boilers or vessel to be heated. This latter point is very important in stoves,
for by this arrangement when a strong fire is wanted for a short time only it may be effected with a comparatively small quantity of coal by raising the grate, while a slow fire may be adjusted at pleasure by lowering said grate. This construction also dispenses with the necessity of cleaning or dumping out the grate when the fire is to be made up in the stove. for the ashes can be riddled out and the cinders thrown up into the upper compartment, the grate swung out, and the kindling put into it and ignited. This done, the grate is swung back and the cinders and coal let down upon it, and the fire is made, thus saving much handling. dust, and dirt; or the igniting of the kindling may be done after the grate is swung back into its place, or after the cinder and coal are let down.
Having thus fully described the nature of my invention, What I claim therein as new, and desire to secure by Letters Patent, is
1. In combination with a stationary upper fire-box, a rocking or swingingfire-box underneath it, havinga flange or cut-off 0 connected thereto, substantially as herein described.
2. In combination with the rocking or swinging fire-box and cut-cit, a rising and falling grate II, substantially as described.
3. In combination with the rocking or swinging fire-box and rising and falling grate, asingle rod or shaft with its cams for operating both, substantially as described.
