TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN H.-KEYSER, of New York city, in the countyand State of New York, have invented a new and improved Coal-Burning Stove; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, making a part of this specification, in which- Figure 1 is an elevation of the front of the improved stove.

Figure 2 is a longitudinal section taken' in a vertical plane through the centre of the stove, showing the interior CDHSiZlllClZlOXl thereof; v

Figure? is a section through the stove, taken in a horizontal plane, indicated by red line a: :1: in fig. 1."

Figure *1 is a side view of the open fire-pot and its support,

Similar letters ofreference indicate corresponding partsin the'several figures.

The nature ofmy invention consists in a stove which'i composed of two apartments, arranged one above the other, with an open-work fire-pot suspended within the upper half of the lower apartment, and Sustained by the cap-plate thereof, said lower apartment being provided with one or more illuminating doors, and adapted to form the main heating and radiating chamber, and also the ash receptacle, while the upper apartment forms the cap of the fire-pot, the entrance for supplying coal thereto, and also the chamber through which the products of. combustion are conducted to the eirit flue; the whole being constructed and arranged in such manner as to afford a very simple andeconomieal coal-burning stove, as will be hereinafter explained.

To enable others skilled in the artto understand my invention, I will describe its eonstructionand operation. In the accompanying drawings A represents the cast-iron hollow base of the stove, which isconstructed with:

a front opening, a, for the removalot' ashes and cinder-s, and also with an annular rim orflange, b, for receiving and having secured to it a sheet-iron cylinder, B. This hollow base A is mounted upon legs, and it may be OOTl structed so as to present a very neat and ornamental appearance. The cylinder B, which forms the body of the stove, and encloses the main heat-radiating chamber, is provided on its upper end with a hollow cast-iron cap, which is made of two-horizontal sections 0 D, secured to said cylinder by the annular flange c. The upper section of this cap is also adapted for receiving and having secured'to it a cylinder, E, of less diameter and capacity than the cylinder 13. The lower cap-section C'is fiat,,and made in the form ofa ring for receiving through it and sustaining'a tapering or flaring'fire-pot, F, as shown in figs. 2 and 4. This tire-pot is'con'struct ed of cast iron, with grated or open-work sides,- and also withan annular flange, (1, upon its upper and largest'end, which flange rests upon the ring C, and thus sustains the fire-pot within the upper half of the cylinder B, free from contact with the cylinder or jacket surrounding it. The lower end of this fire-pot is adapted to serve as bearings for a turning grate, Gr, 01', if desirable, the rod t of this grate may be made of suflicient length to pass through and be supportedby the cylinder B, as shown in the drawings. In the former instance a removable rod or key will be required for shaking the grate, and in the latter instance a handle will be used for this: purpose, applied to the projecting end of said rod. The upper end of the fire-pot or hollow conical grate F is'the only point of this grate by which it is sustained, and this point is prevented from rapid destruction by the heat of the fire, by allowing-of the entrance of cool air through the openings 0 of cylinder 13, which openings are located in such relation to the upper end'of the grate as to expose this end to streams of coolair and keep down its temperature. A slide may be applied to said holes a for regulating the influx of air. The upper section D is secured to the ring section 0 by means of bolts and nuts or other suitable fastening,'so that this upper section can be readily detached when 'it' is, desired to remove the fire-pot for repair or renewal. As the diam-'- eter of the upper ,end of the fire-pot is greater than the diameter of the upper cylinder E, it is necessary to detach the latter, with its base section D, before the fire-pot can'be-taken out of the stove; hence the necessity of having the sections 0 D detachable. It will be seenthat the grated-fire-pot is suspended centrally within the cylinder B, so as to leave an annular space between it and this cylinder for the circulation of air; thus the cylinder is.

protected from destruction by heat radiated from the sides of the open firc-pot. The fire-pot, being thus sus tained and suspended, there will be a free draught of air through every part of its sides and bottom, which air will support combustion at such points and keep up a'brilliant and cheerful fire, from which considerable heat will be radiated. The upper end of the cylinder B beingclosed, except the space occupied by the fire-pot', it

opening coal is supplied to the fire-pot.

will he seen that the entire draught is through the fire-pot, consequently the coals around the open-grated sides of the fire-pot will be kept in an incandescent state, and the greatest amount of heat will be radiated from the cylinder 13, while comparatively little heat will he carried oil through the upper cylinder E. Through the front and upper pai of the cylinder 13 is an opening, J, which should be provided with a mica-light door, through which air inlet openings, corresponding to the openings 0 through the cylinder B, are made, which are provided with a slide or regulator. The opening J is made large enough to expose to view the fire-pot, and also to admit air in large quantities when necessary, which will circulate around, beneath, and through the fire-pot, and not only facilitate combustion, but protect this pot and'its supporting ring 0 from rapidly burning out. Cylinder I) may be provided with several doors, if desirable. The upper cylinder E, which covers the uppercnd of the fire-pot F, hasa feed opening, K, through its front side-which should he closed by a'deor, not shownthrough which Through the rear side of the cylinder E, and near its upper end, an exit opening, g, is-made, which communicates with a vertical flue, it, through which the products of combustion descend and escape from the pipe j. Directly opposite the opening g a register, 8, may beapplied to flue h for admitting cool air and checking the draught of the stove. 1

From the above description it will be seen that my stove consists simply of two apartments, with a removable basket, or open-grated fire-pot suspended within the lower apartment, opposite a transparent or illuminating door, so that during the operation of the stove a brilliant fire will be exposed tovi'cw. The illuminating door may he opened when the fire burns well, and this door may be used as ameans of access to the fire-pot, for poking the fire-pot and clearing its vertical spaces should they become filled with dead einders. As there is no space in my stove cut ofl from the fire-pot, the entire stove, from base to top, will be subjected to the direct heat of the bed of coals.

I am aware that open-grated fire-pots have been employed before my invention, as instanced in the patents granted to Lewis Rathbone and \Villiam Haile, November "21, 1865, and Z. Hunt, June 14, 1864-, and therefore I lay no claim to the invention of an open fire-pot suspended within a stove. My invention relates to a particular mode of constructinga stovcembracing the features above mentioned.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A stove, which is composed of two apartments, 13 E, one arranged below the other, with a removable open-grated fire-pot F, which is provided with a grate, G, said pot being. suspended free from the sides of the lower cylinder B, and sustained by a cast-iron flanged ring, 0, which is secured permanently to cylinder 13, and whichforms the base for and means ofattachment of the castiron section D of the cylinder E, substantially as described.

2. In combination with a grated or open fire-pot, F, suspended within a cylinder, 13, by means of a cap ring,

C, I claim the grate (i when it issustained independently of' the fire-pot and by-the cylinder 13, substantially as described.

3. The combination and relative arrangement of' the air inlet passages c, with a suspended firc-pot, F, and

with the two detachable cast-iron sections C D, substantially as described, and for the purpose of cooling and preventing said sections from warping.

4. An open-grated fire-pot, F, which is suspendedwithin the cylinder B, and combined with the removable sections D E, outlet g,- descending flue k, and. :1. damper, s, the latter being lccated opposi te the outlet g, substantially as described. I i
