JOSEPH WALTER RABBIT, OF AROMA, INDIANA.

PORTABLE FURNACE.

SPECIFICATION forming part of Letters Patent No. 321,332, dated June 30, 1885.

Application filed April 9, i885. (No model.)

T0 @ZZ whom, it may concern:

Be it known that I, JosErH NV. BABBIT, a citizen of the United States, and a resident of Aroma, in the county of Hamilton and State of Indiana, have invented certain new and useful Improvements in Portable Furnaces; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which forma part of this specification, and in which- Figurel is a side view of my improved portable furnace, showing the same to be constructed of two cylinders or compartments. Fig. 2 is a top or plan view ofthe same. Fig. 3 is a perspective view showing the manner of constructing the connecting-flue. Fig. 4 is a horizontal sectional view ofthe furnace, looking downwardlyintothe same. Fig. 5 is a detail view of one of the plates forming the tops of the connecting-flues,and Fig. Gis a top view showing my improvement applied to a furnace having` three cylinders or compartments.

The same letters refer to the same parts in all the figures.

This invention relates to portable furnaces for agricultural and domestic purposes 3 and it consists in the improved construction of a fu rnace of this class having two or more cylindrical drums or compartments, as will be hereinafter more fully described, and particularly pointed out in the claims.

In the drawings hereto annexed, A and A denote two sheet-metal cylinders, open at the top and bottom,and provided near their upper ends with metallic bands or hoops B, serving to brace and stifen the cylinders, and provided with downwardly-extending legs C C, upon which they are supported. The legs are sec cured, near their lower ends, to the sides of the cylinders by means of bails D, thereby increasing the rigidity of the said legs and strengthening the device generally.

One of the cylinders,A, is provided with a door, E, through which fuel may be fed into the furnace; and the other cylinder is provided with a thimble or collar, F, surrounding an opening, G, and to which apipe or smokestack may be attached. The cylinders A and by a plate, K, cut of'a shape to iit the flue.

In this manner the two cylinders or drums are connected rigidly, the connecting-flue H being constructed with double sides formed by the overlapping wings or flaps J, as will be seen more clearly by reference to Fig. L1.

It will be noticed that this way of forming the flue H makes it th ree-sided,or, rather, with` out a bottom. This permits the re to be placed underneath both or all of the kettles being heated, and itwill also permit of the use of long sticks of wood that will reach through both parts of the furnace.

My improved furnace may, when desired,be constructed of more than two drums or cylinders, as will be seen in Fig. 5 ofthe drawings, where three such drums or cylinders have been shown. In such case the several cylinders are connected by dues H, of the construction already described, and the two end cylinders are provided, respectively, with a door, and with a thimble for the attachment of a smokestack.

The operation and advantages of this invention will be readily understood from the foregoing description, taken in connection with the drawings hereto annexed. Kettles or caldrons may be readily fitted to the upper ends of the cylinders. Vood, coal, or other fuel may be used, and grates may be provided for the lower ends of the drums or cylinders,when desired.

Having thus described my invention, I claim and desire to secure by Letters Patent of the United States- 1. A portable furnace consisting of a series of two or more drums or cylinders open at their upper and lower ends, and connected by bottomless flues or passages constructed of wings or iiaps cut from the bodies of the said ICO cylinders, placed together overlapping each legs, and a door and a pipe collar orthimble other, connected by riveting, and provided attached, respectively, to the front and the with top covering-plates,substantially as hererear end cylinder, substantially as herein dein described, for the purpose set forth. scribed, for the purpose set forth. 15

5 2. In a portable furnace, the combination of In testimony that I claim the foregoing as my a series of drums or cylinders, bottolnless flues own I have hereunto afxedmy signature in or passages connecting the same,and constructpresence of two Witnesses. ed of overlapping Wings or flaps cut from the JOSEPH WALTER BABBIT. sides of said cylinders,and suitable top plates, Witnesses:

Io hoops, or bands arranged near the upper ends- WILLIAM COX,

of said cylinders and provided with suitable Lnvs KUNERLTNG.
