EDVARD B. COLBY, OF BROOKLYN, NEW YORK.

HEATING-STOV SPECIFICATION forming part of Letters Patent No. 374,939, dated December 20, 1887.

Application man Apr-n is, resi.

To all whom, it may concern:

Be it known that I, EDWARD B. COLEY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvementsin Heating-Stoves; and I do hereby declare the following to be a full, clear, and eX- aet description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The greatest objection to that class of heating-stoves commonly known as sheet-iron stoves,7 vin which a sheet-metal body is attached, usually by screw-bolts and nuts, to a flange projecting up from a cast-iron base, is that they are dirty or leak ashes and dust all round the bottom of the sheet-iron at the point where it is connected to the iiange of the base, it not being practicable to make the connection dust-tight.

Now, my invention is intended to obviate this objection as far as practicable and still make the sheet-metal body separate from the base, and to provide a simple, durable, and inexpensive connection between the two parts; and it consists of the parts and combinations of parts, hereinafter described and claimed.

In the accompanying drawings, forming a part of this specification, Figure lis a vertical section through a stove-basashowing a portion of the sheet-metal body; and Fig. 2 a perspective view etl my improved connecting-ring.

Similar letters refer to similar parts in both the views. 1

A represents a cast-iron base for a heatingstove of the class described, having a horizontal Harige, a, projecting inwardly all round its upper edge, on which rests and is secured in any desired manner, preferably by screw-bolts and nuts, a ring, B, which, for the purposes of this specification, may be called a connecting-ring,77 although, in fact, it may beof other form than annular. This ring, as clearly shown in Fig. 2, has cast with it or secured thereto in any desired manner a horizontal annular iiange, I), which projects inwardly, and on which rests the fire-brick.

The ring B and base A may be east in one piece, if desired, in which case the flange a will be rendered unnecessary. On the exterior of ring B, I cast or otherwise secure an annular flange, c, which is of greater thickness than Serial No. 234,664. (No model.)

fiange Z, and in the upper surface of the same I form a groove, h, which extends all round a vertical annular flange, d, projecting from the ring B, and t which it is eithersecured or cast. This flange dforms theinner wall of the groove h, and has slots c formed therein,whieh terminate in countersunk openingsor perforations f, formed in the ring, through which screw-bolts are passed to secure the ring, when it is cast separate, to the flange a of the base, the slot e Abeing sufficiently large to permit the use of a screw-driver therein.

E represents a sheet-metal body surrounding and secured to the ange d, the lower edge of which projects into the groove h a sufficient distance below the upper edge of its outer wall to permit the dust and ashes escaping from between the fiange d and the lower edge of the sheet-metal body to fall directly into the groove and not escape over the edge of said outer wall.

Suitable downwardly-projecting lugs, g g', are secured to or cast with the flange b,to form supports for the arms G, whichsupport the grate D. Any suitable arms, C, and lugs gg may be used which permit a dumping and shaking or any other kind of a grate to be employed.

Vhile the ring may be, and preferably is, cast in one piece and annular in form, it may, if desired, be cast in parts and fitted together; or it may be of other than annular formsuch as hexagonal, square, &c.-which is also the ease with its fianges, b, c, and d, and they may also be cast in segments or entire and secured to the ring; or they may, as shown, be cast in one piece with the ring. Therefore I do not desire to be limited to the ring cast in one piece with its flanges, or to the ring and its fianges cast separately but each in one piece, or to the ring and its parts cast separately from the base and secured thereto, as it is obvious they may be cast in one piece with said base with equally as good result.

Having thus described my invention, what I claim 'as new, and desire to secure by Letters Patent, is-

l. The combination, in a sheet-metal stove, of the base A, having an inwardly-projecting horizontal iiange, a, the ring B, having the horizontal flanges `b c, the vertical flange d, and the groove 7L, said groove being formed in the flange c and the sheet-metal body E, whereby ICO the dust and ashes escaping between fiange cl horizontal annular flange for the fire-brick, a and the sheetmetal body Will be caught in said vertical annular flange projecting therefrom, groove, as set forth. and 'means for securing said ring to the base of 2. A connecting-ring of suitable form for astove, substantially as set forth.
