DIVISION A.

j BASE-BURNING- IIRE-PLACE STOVE.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that Letters Patent for DAVID STUART and LEWIS BRIDG-Es Improvements inBase-Burning Fire-Place Stoves were, on June 23, 1868, granted to STUART, PETERSON, AND COMPANY, of Philadelphia, Pennsylvania, of which firm we, the undersigned, DA- VID STUART and RICHARD PETERSON, are the sole members; and we do hereby declare the following to be a full, clear, and cXact-(lcscription of that part of the said invention, which relates more especially to the arrangement, described hereafter, of the interior of the stove.

In order to enable others skilled in the art to make and apply the invention, we will now proceed to describe its construction and operation, reference being had 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; I

Figure 3, a sectional plan on the line 3-4, fig. 2; Figure 4, a sectional plan 011 the line L6, fig. 2; Figure 5, a'sectional plan on the line 7-8, fig. 2;

. Figure 6, a top View of the stove;

Figure 7, aview 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.

The base of the stove will be best observed by reference to figs. 1 and 3, in which A represents the lower plate, the latter being of an oval form, and to this plate are fitted the curved plates B, O, and D, the plates 13 and I) being connected together at their ends by plates a a, in each of which is an opening provided with a sliding door. I

The plate 0 is shorter than the other curved plates,

\ and has two semicircular )ro'ections d and d between which is a partition, e, extending across the space hetween the plates B and O.

It may be stated in the outset that the products of combustion pass downward into the semicircular projection 1!, into the flue E, between the plates 13 and O, thence, in the direction of the arrows, into and through the flue F, between the plates G and D, and thence into the flue G to the semicircular projection d, as shown in fig. 3. I

The upper edges of the plates B G D and a a are closing the fire-chamber K, the fire-pot J, and grate f.

At the rear of the casing I is a curved-plate, M, srcured to the casing I at x at, so as to form the crescentshaped air-chamber N, in which are two pipcs, l and P, the former communicating with the interior of the semicircular projection (Z, and the latter with the semicircular projection d', above referred to. This plate M is so perforated as to admit apleutifnl supply of cold air to the chamber N.

To the upper edge of the casing I is fitted the horizontal flange h, of the casing Q, which is contained within an 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 h of the casing Q, as to leave a space, at, for the admission of air to the space \V, between the casings Q and V.

At the rear of the casing V is a curved plate, R, which, with the said casing, encloses a space separated by a partition,'n, into two compartments 7i and k, with the former of which the fire-chamber communicates through a tube, m.

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

In this cover-plate is an opening, s, to which is fit ted the pipe for conveying the products of combustion from the compartment It to the chimney.

It should be stated here that the pipe 1? communicates with the compartment k, and the pipe P with the compartment It. (See fig. 5.)

A plate, X, is fitted to the upper edges of the casings V and Q, this plate being of the form represented in fig. 6,'soas to leave an opening, X, through which the air heated in the chamber \V, between the casings Q and V, can escape.

From the plate X is suspended the incl-reservoir or feeder'Y, which terminates below in the fire-chamber, this feeder having, at thetop, an opening for the ad mission of fuel which is passed. through an opening in the plateiX above.

The cover consists of two disks, 2 and 3, the former being larger in diameter thanthe latter, and resting on the plateX, while the disk 3 rc'sts on the feeder below the said plate. I

The two disks are loosely connected together by a central pin, 4, so that each disk will be certain to rest on its proper bearing.

The products of combustion can pass between these two covers, that is, between the top of the feeder and p under side of the plate X, thus imparting heat which fitted to the plate H, on which rests the casing I, en-

against which bears the arched plate 6, figs. 1 and 8,

and to the rear of this. plate is secured a casing,,L,

and thence to the chimney.

' on each side of the main body of the stove, the proand up the other to the chimney.

composed of the side plates 7 7', and rear plate 8, the side plates meeting the top plate 9, which is made fiat, as shown in the perspective view, fig. 8.

This casingis fitted into the chimney-place .L, made in the wall 5, and is the recess into which the stove projects. "Through the top 9 of this casing projects the pipe P' for conveying the products of combustion to the flue of the chimney, and in the top 9, immediately above the opening X, fig. 6, is an opening provided with a suitable damper, which maybe so adjusted that the heated air can pass upward into the passage which conveys the heated air to rooms above that in which the stove is'situated, or the damper may be so closed that the heated air will be projected outward into th room containing the stove; When the valve 1 is closed, theproducts of combustion 'will pass from the fire-chamber'through the opening on, fig. -5, into the compartment lc, thence down the pipe 1 into the passage F, fig. 3, along the passage 1* into the passage G, thence through the pipe P to the compartmentk', and thence to the chimney. 0n opening the valve 1), however, the products of combustion will pass directly from the chamber k, through the opening in the partition it, into the-chamber k,

The air admitted through the casing M, at the gear of the stove, into the chamber N, is heated by intimate contact with the outer surfaces of these pipes P and P, and by contact with the back of the casing I, before it passes off through the opening X.

Another and independent volume of air is heated in the chamber W, having been admitted thereto through the opening m in the front of the stove, the air thus heated meeting the other volume of air, and passing with the same through the said opening X On the top of that portion of the stove which pro-' jects into the room is a plate, H, made in the form of a section of a hollowpphere, the plate which rests on the top plate X of the stove, and against'the wall 5, having openings forthe passage 'ef heated air into the room. Y

' The main advantages of the improved stove will be rendered. apparent by comparing it with the ordinary Well-known fire-place stove, of which a View, on a small scale, is shown in fig. 9.

In stoves of this class, there are two pipes, in w,one

ducts of combustion fromwhich pass down one pipe acts Owing to these external pipes, the stove occupies an extended space, and is frequently too large for an ordinary chimney-place; but, by constructing a. stove in the manner described, and by arranging the pipes for the passage of the products of colnbustion' to the chimney within the stove itself, the latter may be made the feeder with fuel from the front, an arrangement which demands a short feeder. By introducing the fuel through the top of the stove, a longer feeder may be used, and this long feeder enables us to form an airchamber, W, which greatly increases the heating-properties-of the stove. t

We claim as the invention of the said STUART and BBIDGE, and desireto secure by Letters Patent- 1. The base of the stove enclosing the passages E, F, and G, arranged and communicating with the pipes P and P, substantially as described.

2. Two or more pipes P and P, arranged within the outer casing of a fire-place stove, for conveying the products of combustion to the chimney, and for heat.- ing the air admitted to the space within the said outer casing-all substantially as and for the purpose herein set forth.

3. The pipes P and P, in combination with the compartments k and k, and the valved partition between the same.

' 4. The double cover, consisting of plates 2 'and 3,,

one for fitting to the top of the stove, and the other to the top of the feeder, and so. arranged that the products of combustion can pass between them.

In testimony whereof, we have signed our names to this specification, before two subscribing witnesses.
