STOVE.

SPECIFICATION forming part. of Letters Patent No. 341,363, dated lVIay 4, 1886.

Application filed April 30, 1883. Serial No. 93,378. (No model.)

To all whom it may concern.-

Be it known that I, FREDERICK WILL, of Rochester, Monroe county, New York, have invented a certain new and useful Improvement in Stoves; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings. in which- Figure 1 is a longitudinal vertical section of a stove, showing my improvement. Fig. 2 is a cross section of the same in line x z of Fig. 1, enlarged. Fig. 3 is a similar view in line y 1 Fig. 4 is a similar view in line 2 2. Fig. 5 isa vertical section in line in w of Fig. 2.

My improvement relates to parlor-stoves of square form in cross-section; and it consists of such a stove provided with a circuhn-fire-pot and a removable magazine, and having four revertible flucs, at the four corners, of peculiar construction, as hereinafter described.

This stove is of the form of ordinary square parlor-stoves well known. Heretofore in such stoves a square or oblong tire pet has been used, conforming to the square or oblong outline of the stove. In place of'such square fire-pot I employ a circular one, similar to that used in cylindrical stoves, and I employ, in addition thereto, a downward flue in each corner of the square stove, which flues have a I circuitous connection with the base, from which the products of combustion after heating the base pass off through an exit-flue in the rear to the smoke-pipe.

In the drawings, A shows the body of the stove, which is square in cross-scction, and B is the circular fire-pot, resting loosely therein on flanges a a, so that it can be readily removed upward and taken out bodily through the door b, which is of sufficient size for the purpose.

0 is the magazine, resting at its top on flanges c c, and is also removable. In removing the fire-pot it is necessary to first remove the magazine.

D D and D D are the four revertible fines in the four corners of the stove. They open from above the fire-pot and extend down vertically, and carry the heat and the products of combustion down into the hollow base E by the following means:

G G are two horizontal flues at the sides of the stove just above the base, which extend from front to rear. They are shown more particularly in the crosssection, Fig. 3, and vertical section, Fig. 5, and are indicated by the dotted lines in Fig. 2. The verticalfiues D D do not extend through the horizontal lines, but simply open into them at their ends. At the rear ends of the horizontal fines are ports or openingsd d, which open downward through the plate and communicate with the base 13.

The ports come directly under the rearvertical lines, D D, so that the currents from the latter have a direct and straight course down into the base; but the currents from the front vertical flues, D D, have an indirect course, first passing into the end of the horizontal fines, and thence passing along the whole length of these horizontal flues, and finally passing down the ports (I d, uniting in common with the volume from the rear vertical fines. By this means the sides of the stove are heated. In the hollow base are two'vertical plates, H H, as shown in the crosssection, Fig. 4, and as indicated by the dotted lines in Fig. These plates are set near, the sides at the rear, but converge toward the front. These plates form due-passages in the base on each side, receiving the draft from each of the ports (I, condncti ng it forward toward the front of the stove, and then, after it has passed the front end of the plates, turning it inward between the plates, as indicated by the arrows in Fig. 4, where it finally escapes up the back fine of the stove.

is a central port or passage opening from the rear of the hollow base up through the top plate into the back line, I, of the stovc,through which fine the products of combustion, after escaping from between the plates in the base, pass, and finally escape through a smoke-pipe, K, into the chimney. Above the back line is a boiler-opening, g, which receives heat from an open space, 71, above the fire-pot.

The construction of the does, as above described, is especially adapted to a square stove provided with a circular fire-pot. The corners left by the circle of the fire-pot furnish ample space for the vertical fines. Thelatter conduct the heat down into the horizontal fines, and here,owing to the fact that the front ends of the horizontal fines are closed and the rear ends alone have discharge-passages into the base, the heat which passes down the front vertical fiues has an extended passage at the sides of the stove,whicl1 keeps said sides constantly heatedan effect not accomplished in ordinary square stoves of the kind. On entering the hollow base through the ports d d the heat is again turned forward by the plates H H, and is again turned backward between the plates, and thus a zigzag course is made forward and back, which is most effective in extracting the heat before the final escape.

In the throat, between the fire-space l2 and the back fine, I, is a valve and deflector, constructed as follows: 7c is a fixed plate set in an inclined direction across said throat, one edge connecting with the top plate of the firepot support, the other edge connecting with the fine-plate above the smoke-pipe K, as shown in Fig. 1. On top of the fixed plate is a sliding plate, Z, of similar for1u,and provided with a stem, m, which extends outward through the stove, and by which the sliding plate is operated. Both plates are provided with or dinary register openings orslots, a n, as shown in Fig. 2. By sliding the upper plate the reg ister may be opened, in which case the direct draft from over the fire-pot can pass straight to-the smoke-pipe without passing through the revertible fines; or by sliding it the other way the register can be closed, thereby forcing the draft to pass down the revertible fines and take the indirect course before described. By this means, even when the register is closed and the draft is passing through the downward fines, the heat from the fire always passes direetl y through the open space h to the boiler, which is notthe case where an ordinary shifting valve is used, which covers one fine as it uncovers the other. Another advantage results from the inclined position of the register-Valve, which serves as a deflector to throw the heat upward to the boiler.

Having described my invention, I elainn 1. In a square stove having a removable fire-pot, the combination of the four revertiblc fines D D D D in the four corners of the stove, the two horizontal fines G G at the sides of the stovejnst above the hollow base, and the ports or passages d d through the top plate of the base, the two front vertical fines opening down into the ends of the horizontal fines, and the two rear vertical fines opening directly down into the base through the ports (I (Z, asherein shown and describedf 2. In a square stove having a removable fire-pot, the combination of the four revertible llues DD D D at the corners of the stove, the two horizontal lines G, G at the sides of the stove, the ports or passages d (1, opening through the top plate of the base and located directly under the rear vertical fines, and the two side fines in the hollow base formed by the plates H H, as herein shown and described.

3. In a square stove, the combination, with the fire-pot B and the discharge-fine I, of the register-plates k I, extending angnlarly across the flue and resting above the exit-pipe K, and a seat provided with a boiler-hole above the register, with a clear passage extending from the fire-chamber to the boiler-hole, as shown and described, and for the purpose specified.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
