Letters Patent No. 66,969, dated July 9.3, 1867.

GOAL-STOVE.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN H. KEYSER, of New York city, in the county and State of New York, have invented a useful Improvement in Stoves; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being bad to the accompanying drawings, making part of this specification, in which i i I Figure 1 is a front elevation ofa conical stove having my invention applied to it.

Figure 2-is an elevation of one side of the stove.

Figure 3 is a vertical central scctionof the-stove.

Figure 4 is a section through the stove, taken in the horizontal plane indicated by line a: x in fig. 3.

Figure 5 is a perspective view of the movablejacket detached fromthe stove.

Similar letters of reference indicate corresponding parts in the several figures.

This invention relates to an improvement in circular coal-stoves which are provided with an interior open fire-pot, and illuminating doors or windows through which the fire is exposed so as to present'a cheerful appearance. The invention is designed for all varieties of circular stoves having illuminating windows or doors for exposing the fire, whether of a cylindrical or conical form, and whether base-burning or surface-burning, and whether made wholly of cast iron, or partly of cast iron and partly of wrought iron.

The nature of my invention consists in the application, to the outside'of that part of the body of a. stove through which there are made two or more illuminating doors or openings, of a circularly adjustable jacket, through which there are openings corresponding in number and size to the openings through the body of the stove, said jacket being adapted to serve as a means for converting an open cylinder stove into a close cylinder stove, and exposing more or less of the fire through the several openings, as may be desired.

To enable others skilled in the art to understand my invention, I will describe its construction and operation.

In the accompanying drawings I have represented my invention applied to a cast-iron conical stove, but I do not desire to confine myself to this form of store, as I contemplate applying my invention to cylindrical stoves and ornamental circular stoves of various forms or designs.

The store consists of a base-section, A, a conical body, I), an intermediate section, C, and an enlarged chambered cap, I). The several sections may be connected together by bolts and flanges, or in any suitable manner. The cup D is constructed with an interior annular flange, a, upon which an open fire-pot, E, is sustained by its flange 1, so as to extend down nearly to the base of the section B, as shown in fig. 3. The coal is supplied to the tire-pot through an opening which is made through the crownof the cap C, and the smoke passes oil' through the chamber 0, which is formed by the walls of the cap, as shown. The intermediate section 0 and the section may be connected together by means of a flanged ring, F, which is so constructed as to serve the double purpose of a guard and of a foot-rest. This foot-rest I intend shall form the subject of a separate application for a patent, and for this reason it will not be claimed here. For the purpose of exposing to view the burning coals in the fire-pot E, two or more openings 0 c are made through the body 13 of the stove, of any suitable height and width. This portion B of the stove should be circular, and surroundingit is ajacket, G, through which openings care made, corresponding in size and shape to the openings 0. This jacket fits snugly but loosely upon the body 13, and it is supported upon the ring F, so that it can be easily turned partially or entirely around when desired;

The object of the jacket is to allow all the openings 0 through the body of the stove to be closed simultaneously, when a close stove is required, and to be opened when it is desired to expose the tire. The openings through the jacket may all be provided with mica light doors, or close doors, or mica lights may be applied to all but one of the said openings, and that one provided with a door. And for some kinds of stoves the doors and mica lights may be omitted, and the stove used as shown in the drawings.

\Vhen it is desired to shut up the openings 0 through the body of the stove, so as to make a close body, it is only necessary to more thejaeket around until those parts of it which are between its openings 0 are brought opposite the said openings c, as shown in fig. 2. In this condition of this stove the fire-chamber will be closed and the grate can be shaken or the fire-pot emptied without having any of the dust escape into the room.

When thefire burns brightly, and it is desired to expose the fire and allow the heat to escape readily into th room, the jacket is moved back and the openings all exposed, as shown in figs. 1, 2, and 3.

I am aware that it is not new to employ a sliding segment having openings through it corresponding to i openings through the body of the stove. Such contrivancc will be found in the patent granted to B. F. Raney, September 24, 1861, and alsoin many other stoves.

I am also aware that an annular band, having openings through it corresponding to similar openings through the stove to which such band is applied, will be found in the patent granted to Evans Ba.ckus,'March 10, 1863. To these contrivances I lay no claim. It will be seen by reference to the drawings that I employ the jacket or conical shell G in'conjunction with a suspended fire-pot, E, the Whole of which is'exposed by the openings 0 a when said jacket is brought in the position shown in figs. 1 and 3. This allows of the radiation of both light and heat, and exposes a bright fire. It will be seen also that the jacket G is supported upon the foot-rest or guard F and kept down in place thereon, but allowed to turn by the-overhanging cap D. This arrangement will allow of the free escape of ashes or pieces of cinder which get between the jacket and stove-plate, and thus prevent the clogging of thejacket.

Having described my invention, what Iclai'm as new, and desire to secure by Letters Patent, is

1. The application to a stove, of the form and character described and shown, of a. conical jacket, G, which is provided with openings 0 a corresponding to openings c a through the body of the stove, substantially as described.

2. The parts 13, C, and D, in combination with the conical jacket G, and a suspended open-work fire-pot, E, constructed substantially as shown and described. v

3. The relative arrangement shown and described of the openings 0 through the conical jacket G, the openings 0 through the stove, and the suspended open-work fire-pot E. i
