ERNST H. HUENEFELD, OF CINCINNATI, OHIO.

WOOD-BURNING STOVE.

SPECIFICATION forming part of Letters Patent No. 633,720, dated September 26, 1899.

Application filed December 28,1897 Serial No. 664,044. (No moclehl To r/f/l 1071/0111, it may concern:

Be it known that I, ERNST H. HUENEFELD, a resident of Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in \Vood-B urning 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 to make and use the same.

My invention relates to an improvement in wood-burning stoves, and is designed more particularly as animprovement on the stove shown in my Patent No. 601,556, granted to me March 29, 1898.

The object of the present invention is to provide for the ready removal and replacement of the fire-pot or any part of same, so that when any part of the fire-pot becomes worn or burned out it can be replaced by the owner of the stove without the aid of skilled labor.

iVith this object in View myinvention consists in the parts and combinations of parts and in the details of construction, as will be more fully described, and pointed out in the claims.

In the accompanying drawings, Figure l is a view in elevation of a stove embodying my invention. Fig. 2 is a view in vertical section of same. Fig. 3 is a view in horizontal section on the line as 0; of Fig. 2. Fig. a is a view of the top plate of the fire-pot detached. Fig. 5 is a top view of the bottom plate, and Fig. 6 is a perspective view of the smoke-pipe collar.

A represents the outer jacket, preferably I rectangular longitudinally and square transversely. This jacket is preferably made of sheet metal and surrounds and contains the cylindrical fire-pot B. In my former application above referred to this fire-pot is made up of a cylindrical body with top and bottom sections rigidly fixed thereto. 1n the present instance this fire-pot is made up of a cylindrical body a, preferably of sheet metal, and a removable top I) and removable bottom 0, preferably of cast-iron, the top and bottom sections being provided each with a rim d on its inner face, adapted to fit within the adjacent open end of the body a of the fire-pot, and thus not only prevent the ends 1 or 0 from slipping or moving laterally on the body, but also prevents the body from collapsing at its ends and makes-the fire-pot practically air-tight. The top or top plate bis provided with a central fuel-opening bounded by a vertical rim or collar f, which latter projects up through the openingin the top of the outer jacket, and the top I) and rim f are reinforced and strengthened by the ribs g, which latter are integral with both and form seats for the top plate of the outerjackets, and thus oper ate as spacing-blocks to hold the top plate of the jacket and the top of the fire-pot the required distance apart. The bottom plate 0 is provided on its lower face with ribs h, which latter are for the purpose of adding strength to the plate. The body and the top and bottom plates are removably secured together by the bolts h, passing through lugs tin the top plate I) and down through lugs t" on the bottom plate 0. These bolts are preferably headed or bent at their upper ends and screw-threaded at their lower ends for the attachment of the nuts j. Hence it will be seen that by removing the nuts the parts can be separated for repair or removal.

Loosely seated on the lower plate 0 within the body a of the fire-pot is the lining F. This lining fits loosely within the body and rests on the bottom plate. Hence by removing the top plate I) the lining, which is preferably made of sheet metal, can be removed for repair or removal.

The body a of the fire-pot is provided near its bottom with an opening 7;, reinforced on its inner face by the cast-metal plate 70', having an opening therein corresponding to the opening 7.; in the body a. Secured to the outer face of the body a and to the reinforcing-plate k is the flue-box I. This box is carried wholly by the fire-pot and is provided at its lower inner end with an opening registering with the opening 70 in the firepot and near its upper outer end with an opening corresponding with a similar opening in the outer jacket. From this it will be seen that this draft-box is located within the air-space between the outer jacket and fire-pot, and the air as it enters passes down within the box and escapes into the fire-pot near the lower end of the latter. The fire-pot also carries near its upper rear side the smoke-collar L.

This collar is preferably made of cast metal arrangement of the several parts herein and projects through a corresponding opening in the jacketand is provided with the rigid or, if desired, integral spacing-blocks Z, which latter form bearings for the outer jacket at this point.

To attach the fire-pot to the jacket, the parts of the form er are assembled as described and introduced into the jacket through the lower open end of the latter. Screws m are then passed through the flat metal ring N, resting on the top of the jacket and around the rim, a flange surrounding the fuel-open ing in the top plate, and into screw-threaded openings in the top plate I) of the fire-pot. I prefer, however, to employ screw-bolts and pass them through the top plate of the tirepot and secure them by nuts 92, as shown. This construction and arrangement would support the fire-pot; but in order to take part of the weight from the top of the jacket and also to hold the fire-pot in its proper relative position within the jacket I prefer to employ the braces 0. These braces 0 may be integral with the bottom 0 of the fire-pot or may be secured thereto and are provided at their ends each with an opening for the passage of a screw-bolt through the outer jacket. In order also to further brace the parts, hold them in position, and assist in taking the weight of the fire-pot and its contained fuel, I secure the parts together around the smokeflue and around the draft-box by screw-bolts and nuts passing through reinforcing-rings, the jacket, and the fire-pot. By removing these screw-bolts, together with the bolts connecting the top plate and the bolts connecting the braces carried by the lower plate, the

fire-pot and its attached parts can be withdrawn from the jacket and any of its parts renewed or repaired. \Vith this construction the cylindrical fire-pot is slightly less in diameter than the shortest diameter of the jacket, thus forming restricted air-space at the points centrally between the angles or corshown and described without departing from the spirit and scope of myinvention. Hence I would have it understood that I do not limit myself to the precise details herein shown and described, but consider myself at liberty to make such changes and alterations as fairly fall within the spirit and scope of my invention.

I-Iaving fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a stove the combination with a jacket open at its bottom, of a fire-pot suspended from the top of the jacket and comprising separable body, and top and bottom plates, and bolts depending from the top plate outside of the body and removably supporting the bottom plate in position against the lower end of the body.

2. In a stove, the combination with a jacket open at its bottom and provided with a fuelopening, of a fire-pot having a fuel-opening corresponding in position with the opening in the jacket, the said fire-pot comprising separable body and bottom and top plates, the top plate being secured to the under side of the top of the jacket, bolts depending from the top plate outside of the body and removably supporting the bottom plate against thelower end of the body, and a removable lining resting on the removable bottom of the fire-pot, substantially as set forth.

3. In a stove, the combination with a jacket open at its bottom and provided with a fuelopening, of a fire-pot comprising separable- ERNST H. HUENEFELD.
