the Schedule referred to in the Letters Patent and making put of the same.

It all whom it may concern Be it known that Letters Patent for DAVID STU- ART and Laws Bsrness Improvements in Base- BurningFire-Place Stoves were, on June 23, 1868, granted to STUART, Pn'rnnson 8t 00., of Philadelphi'a, Pennsylvania, of which firm we, the undersigned Dsvm Swsm' and Brennan Pn'rnasox are the sole members; and we do hereby'declare the following to he a full, clear, and exact description of that part of the bad to the accompanying drawing, which forms a part of this specification, and in which--' Figure 1 is a front view of the improved fire-place stove;

Figure 2, a vertical section on the line 1-2, fig. 1; Figure 3, a sectional plan on the line 3-4, fig. 2; Figure 4, a sectional plan on the line 5-6, fi 2;

Figure 5, a sectional plan on the line 78,'fig. 2 Figure 6, a top view of the stove; Figure 7, a view of the covers of the feeder; Figure 8, a perspective view of the casing to fit in the fire-place, and receive the stove; and

Figure 9, a. diagram, showing a front view of a fireplace stove of the ordinary construction.

A is the oval base-plate of the stove, and to this base are fitted the curved plates B, O, and D, the plates B and D being connected together at their ends by plates 0 a, in each of which is an opening provided with a sliding door. The plate 0 is shorter than the other curved plates, and has two semicircular projections, 11 d, between which is a partition, 0, extending across the space between the lates B and G.

A plate, ,is fitted to the upper edges of the plates B, 0, D, and a a, and on this plate rests the oval casing I, iuclosing the fire-chamber K, fire-pot J, and

. At the rear of the oval casing I is a curved plate, M, secured to the said casing at a: :c,so as to form the cresoent-shaped air-chamberN,in which are two pipes,

To the upper edge of the casing I is fitted the hori'zontal flange h of the casing Q, which is contained within the exterior casing V, the latter being fitted to a plate, T, which rests on the curved plate M, but is so far above the flange hof the casing Q as to leave a space, m','for the admission of air to the space W, between the casings Q and V.

At the rearof the casing V is a curved plate, R, which, with the said casing, incloses a space separated by a partition, n, into two compartments k and k, with the former. of which the fire-chamber communicates through a tube, m.

The partition n, between the two compartments,has an opening, provided with a throttle-valve, p, the spindle of which passes through a cover-plate, q, and is provided with an arm, t, to be operated by a rod, 1, fig. 6. p

In this cover-plate is an opening, S, to which is fitted a pipe, for conveying the products of combustion from the compartment k to the chimney.

It should be stated here that the pipe I communicates with the compartment is and the pipe P with the compartment k, (see fig. 5.)

A plate, Z, is fitted to the upper edges of the cas ings Vand Q, this plate being of the form represented in fig. 6, so as to leave an opening, X, through which the air heated in the chamber W, between the casings Q and V, can escape.

From the plate X is suspended the fuel-reservoir or feeder Y, which terminates below in the fire-chamber, this feeder having at the top an opening for the admission of fuel, which is passed through an opening in the plate X above.

The cover consists of two disks 2 and 3, the former being larger in diameter than the latter, and resting on the plateX, while the disk 3 rests on the top of the feeder, below the said plate. The two disks are connected together by a central pin, 4, so that each disk will be certain to rest on its proper hearing.

The products of combustion can pass between these two covers, that is, betweenthe top of the feeder and under side of the plate X, thus-imparting heat, which wonld be lost, if the feeder extended to the plate X, and a single cover only were used.

In fig. 5 the line 5-repr'esents the face of a wall or.

P, for conveying the products of combustion to the flue of the chimney, and in the top of the plate 9, immediately above the opening X, fig. 6, is an opening provided with a suitable damper, which may be so adjusted that the heated air can pass upward into the passage which conveys the heated air to the rooms above that in which the stove is situated, or the damper may be so closed that the heated air will be .pro-

jected outward into the room contaiuing the stove.

Although we have described fully the several parts which relate to the internal arrangement of the stove, it will not be necessary to give here a further explanation of the operation and duties of these parts, as they are fully described in Division A of this application for a reissue of the aforesaid patent of STUART, PETERSON 8t 00., dated June 23, 1868 We will therefore proceed to describe those features to whichthis division of the said application more especially relates.

On the top of that portion of the stove which projects into the room is a plate or screen, H, which, in the present instance, is made in the form of a section of a hollow sphere.

This plate bears with one edge against the face of the wall or chimney-piece, and rests with its lower edge on the top X of the ,stove, and thus efl'ectually crating the damper 10, while it serves to distribute the heated air into the room.

The screen, however, is so hinged to the stove", either in one or two parts, that, when access to the handle or feeder becomes necessary, the said screen can be moved on one side.

-We claim as the invention of the said STUART and BRIDGE, and desire to secure by Letters Pateut' The combination, substantially as described, with a or screens, attached to, but movable on the stove.
