"BASE-BURNING- STOVE.

Thefichedule refen'ed to in these Letters Patent and making part of the same I To all whom these prcsents shall coo nc: l

r Be it known that I,'WATSON SANFORD, of the city,

First, to the construction of the upper part of the coal-receiver or chute.

Second, in the arrangement of an adjustable passage-way immediately above and to the chute, in order to permit of the easy removal and replacement of the latter. g

Third, in the arrangement of divisional strips or partitions, placed between the chute and the outer casing.

Fourth, in the arrangement of a horizontal slide damper under the escape-pipe, and about midwaybe tween the top and bottom of the chute.

Fifth, in the arrangement of the grate, so to permit of its being easily removed.

Sixth, in attaching and arranging the foot-ring. To enable those skilled in the art't'o construct and use my improvements, I will proceed to describe their construction and operation.

a is the chute or coal-receiver, for a short distance on the upper portion of which I construct the open or basket-work I).

sen and prevent the explosion of gases in the coalreceiver. This has been troublesome and annoying in this class of stoves, as when such gases accumulate in the chute, they become fixed, and explode, thereby frequently injuring the stove. By reason of this invention, such gases will 'throw up the inner cover 0, and pass oil through the open-work, into the escapepipe cl.

e is a rim or ring, taking up a portion of the top of the stove, which rim is made wide enough, so that when removed from the top, it forms an opening at e, in direct ,contact with and of larger diameter than the chute, and which will permit of the ready withdrawal of the chute.

This rim is held in place by'resting on, and being fastened with iron or wire bolts down to, the lugs f, f,

&c., projecting from the inside of the top portion of the stove, g, within which this rim fits. This is of great importance,.if it is desired to get at the coalchute in order to repair or clean it. Heretofore, the

repairing has been done at much trouble and expense.

h h are metal strips, or divisional plates, which are of the-width of the passage or circular flue between the chute and body of the stove, fastened at their lower extremities to a horizontal strip, .t', dividing horizontally the back part of this whole passage-way.

These strips extend up two-thirds of the way to the top of the stove, or more, and are constructed so that an additional piece placed on each, made in an anguvlar shape or in a slide form of construction, can be moved up and down, so as to increase or decrease the length of the division-plate, and thus render more or less effective the throwing of the heat to the front or rear of the stove; or it can;by means of a slide-damper, j, in the horizontal strip or division-plate i, be left free to pass up equally. around the body of the stove. The verticaldivisionplates can be left single, that is to say, not adj ustablc, if desired. These being also screwed down to the plate a, as shown at k k, admit of their easy removal for packing separately, thus avoiding breakage. V

j is a slide-damper in platev i, containing several openings, and its arrangement. at this point of the chute will admit of direct draught from the'fire to the smoke-pipe, at the time of kindling. the fire, which, with the aid of the division-strips, mainly confines the products of combustion to the back of the stove, as in a chimney; then, after the thorough ignition of the fuel, the heat can be thrown mainly to the front part of the stove by closing this damper.

m is a slot in the rim m, containing the sockets for the grate-bar, through which slot can pass the projection n, on the grate, thus enabling the grate, when such projection is opposite the slot, to be let down and removed away, by reason of one of the trunnions passing out of its socket, such socket being cut away on its front side, as shown at n. ience, in case of removal, required for cleaning or repairs.

0 is the fire-pot, which, in this class of stoves, has been heretofore cast in sections, and where the heat has been intense, the sections have opened, thus permitting gases and dust to escape. The brick being laid solid in this bowl, and angular, and to the shape of it, admit of a direct and intense radiation of heat down tothose portions of the floor immediately at the base of the stove. i I

p is a foot-ring, which is in position about on a line with the top of the fire-chamber, and is attached to brackets, q q q, which take into slots placed on the under side ot'the ring.

The horizontal portions of the brackets are fitted to- This is of great convena small rim, 1', cast around the stove, almost in the same horizontal plane as the foot-rest. The other arms of the brackets rest down on the store, at or near the lower part of the fire-pot.

These improvements all tend to render more effective this class of stove, and their respective features of utility are apparent.

\Vhat I claim as new, and desire to secure by Letters Patent, is

1. The arrangement of open-work at the upper portion of the chute, substantially as described.

2. The an'angementof an additional opening or passage-way to the chute, and in direct contact therewith, and of larger diameter, to admit of a more convenient withdrawal or replacement of such chute, substantially as described.

3. The arrangement of divisional plates or strips longitudinally between the chute and body of the stove, substantially as described.

4. Making such divisional plates or strips adj ust-able, substantially as described.

5. The arrangement of a slide-damper horizontally between the chute and body of the stove, substantially as described.

6. The construction of the grate and rim containing the trunnions, to admit of the removal of the grate, substantially as described.

7. The arrangement of the foot-ring, when combined with the brackets q q q, substantially as described.
