HEATING-DRUM.

SPECIFICATION forming part of Letters Patent No. 223,715, dated January 20', 1880.

Application filed February 8, 1879.

I exact description of the same.

The object of my invention is to provide an improved heating device of thekind forming for connection with stove-pipes. 0, 1s pivoted in the lower collar, 1). The lower an attachment or appendage of a stove or furnace pipe, and commonly employed as a substitute for a stove or grate in apartments contiguous to that in which is situated the stove or furnace with which such pipe connects.

The construction of the drum is as hereinafter described, the same being shown in accompanying drawings, forming part of this specification, in which- Figure l is a vertical central section of the drum, and Fig. 2 avertical section on line now of Fig. 1. Fig. 3 is a vertical central section of a drum having a modified construction, and Fig. 4 is a side view of the same.

The body of the drum is formed of the three superposed parts or sections A B G, which are oval in cross section and graduated in size, the middle part, B, being smaller than the lower part, A, and larger than the upper part, G.

Referring particularly to Figs. 1 and 2, the lower and upper parts or sections, A C, have collars a b at top and bottom to adapt them A damper,

part, A, has a series of vertical tubes, D, ar ranged near the shell or casing, and open at top and bottom, so that air has free passage through them. In said Figs. 1 and 2 a perforated detachable oval cap or collar, E, is shown placed upon the laterally-projecting top portion of part A, and surrounding the base of section B. Said cap serves partly as an ornamental appendage of the drum; but its practical function is to break up the currents of heated air rising from tubes D, and it thus aids in distributing the heat in the apartment in which the drum is located.

In the interior of the drum are placed four concavo-convex-plates, which are arranged horizontally, and serve to'deflect thecurrent of heated air, smoke, and gases of combustion entering through the stove-pipe at a. The small deflector F is placed directly over the tion entering at b strike against the under side of deflector F, and are thus diverted and directed beneath the lower deflector, G, which in turn directs it laterallyagainst the tubes D and the adjacent side of the drum. The latter (tubes and side of the drum) thus become heated, so that currents of heated air are established through the tubes, as will be readily understood.

The deflector H supplements the function of its companion G, and the upper deflector, I, again diverts the current laterally. Thus the heated products of combustion are caused to project laterally against and take their general course alongside the walls of the drum, so that the heat is utilized as fully as practicable without serious obstruction of the apartment the heated airrisin g from tubes D.

The employment of the stove K renders it practicable to derive a sufficient' supply of heated air for this purpose.

I do not claim, broadly, the employment of deflectors or heat-distributers in .a stove, heater, or drum, nor providing such drum or heater with open-ended tubes for passage of heated air.

What 1 do claim is-- The improved heatingdrum consisting of the body A B 0, provided with top and bottom openings, and having open-ended tubes D, arranged. as specified, and the deflectors arranged horizontally, all as shown and described. I
