"STOVE.

SPECIFICATION forming part Of Letters Patent NO. 609,768, dated August 30, 1898. Application filed August 16, 1897.; Serial No. 648,378. (No model.)

To all whom, it may concern.-

Be it known that I, WI LIAM W. BALDWIN, acitizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Stoves; and I do hereby declare the following to be a full,-clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide a coal heating-stove which may be simply and cheaply constructed and in which such provision shall be made for the drafts through the coal and such course provided for the heated gases, air, and smoke as shall insure a large heating capacity.

The invention consists in part of a sheet or cast iron inclosing drum, a fuel-pot within it, and a shield or deflector causing the heated products of combustion to come into intimate contact with the drum.

Another part of the invention consists in providing the fuel-pot with openings in its side adapted to allow the exit of gases, but

not of coal.

In the drawings, Figure 1 is a vertical central section of my improved stove. Fig. 2 is a rear elevation of the fuel-pot and ash-box. Fig. 3 is a plan of the fuel-pot with the back sections removed, and Fig. 4 is a detail view of one of the back sections.

The casing of the stove consists of the top plate a, the bottom plate a, each preferably made of cast iron, and the approximately cylindrical drum a, connecting the two and made preferably of sheet-iron. The rods a, extending from the top plate to the bottom, securely hold the casin g together. The stove is elliptical in horizontal section, Fig. 1 of' the drawings, being divided on the major axis of the ellipse.

At the front end of the stove the sheet-iron drum 0. is discontinued and its place is taken by the cast-iron plate a secured at its top and bottom by the cast-iron plates a and a and at its sides to said drum.

13 represents the fuel-pot, which is made of cast-iron and is in the shape ofan inverted conoid open at the top and bottom. Its front plates c and a.

side isformed. into a pitcher-spout b, which joins and is secured to the plate a there being an entrance L opening in said. plate 0pposite the pitcher-spout. The fuel-pot is secured at its lower end to the plate C, which forms the top ofthe ash-box. The bottom a of the stove forms the bottom of this ashbox. The front end thereof is open, while the rear and two sides are formed by vertical Within the ash-box, just below the bottom opening of the fuel-pot, is the grate D, made of suitable construction and supported in' suitable manner. A door a provides an entrance-opening for the fuel and a door a? an exit for the ashes and access to the grate.

The rear side of the fuel-pot casting does not extend up as high as the remainder, and thereby leaves an opening I), which extends approximately half-way. down from the top of the fuel-pot and laterally nearly a semicircumference. This opening is closed by separate sections E. Each of these sections is itself an integral piece of cast-iron having overlapping slats e, which'leave spaces 6 between them after the manner of a louverwindow.

The sections E are secured to the casting B by the following means: A flange 1) projects rearward from the upper edge of the rear portion of the fuel-pot, and in this flange are formed holes 19 Secured across the opening b at the rear side of the fuel-pot is the band b which is riveted at its ends to the fuel-pot directly and is supported intermediately by the arms 17 which are formed integral with the fuel-pot and extend upward at the rear side thereof, as shown. At the base of the sections E are the lugs e and at the rear sides are the hooks a both the lugs and hooks being cast integral with the sections. These lugs take into the holes b while the hooks hook over the band 12 The arms 11 are so placed that either of them forms a support for the contiguous edges of two proximate sections E. Thus the sections are securely held in place.

A flanged hole a is provided in the top plate a for the exit of the smoke and gaseous products of combustion. A shield F, preferably mo semicylindrical in form, depends from the plate a in' frontof this exit-hole to a point below the louvered sections E. This shield causes the gaseous products, of combustion to travel downward after leaving the fuelpot, whereby. they are brought into intimate contact with the sheet-metal walls of the stove. A cleaning or cooking hole a is supplied through the plate a over the fuel-pot and is closed normally by a cover of any suit-.

aerated a more' intense combustion takes.

place than if the sole exit of the draft was at the surface of the fuel. The smoke and gaseous productsof combustion, the course of which is shown by the arrows in the drawings, pass out through the louvers and from the top of the coal and heat the sheet-metal surface a above and at the sides of the fuelpot, and then, passing downward between the fuel-pot to the shield F, heat the said sheetmetal surface below that shield, and, passing up back of the shield out of the hole of, heat the rear of the sheet-metal surface and its sides near the rear. It will thus be seen that substantially the whole of the drum a may be heated to a high degree, or, rather, the drum being of sheet metal a large amount of heat will pass through it in all directions. Having described my invention, I claim- 1. A stove fuel-pot, open at its upper end and having on one side a rigid pitcher-spout and having a portion of its opposite side cut away, said cut-away portion being occupied by sections which are separable,removable,

and have openings through them, substantially as described. i l

2. The combination, with a stove having an entrance door a and an ash-box which has a top plate 0, of a fuel-pot B joining at its bottom said top plate 0, and having at its front a pitcher-spout 1) leading to said entrancedoor, and having at its rearreinovable perforated sections E, substantially as described.

3. In combination, a fuel-pot B open at its upper end and having a portion of its side cut away from said upper end, the band 12 secured to said fuel-pot across said cut-away portion, and a plurality of sections E having orifices through them and adapted to occupy said cutaway space and be supported by said band, substantially as described.

4:. In a stove, in combination, a fuel-pot B having a portion b cut away in the side wall from the upper end, arms 5 projecting upward from said fuel-pot outside of said cutaway portion, a band 19 supported by said arms, and the separable sections E adapted to occupy said cut-away portion and be supported by said band, substantially as described.

5. In a stove, a fuel-pot B having a portion of its side wall cut away from its upper edge, a flange b projecting outward from the firepot at thebase of said cut-away portion, holes in said flange and separable sections E adapted to occupy the portion cut away and having lugs e at their lower ends adapted to take into'------ said holes, and means for holding said sepa rable sections in place, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

WILLIAM W. BALDWIN.
