SPECIFICATIONforming part of Letters Patent No. 240,065, dated April 12, 1881.

Application filed J annary 31, 1881. (No model.) *Y

Astoves wherein the products of combustion are prevented from escapin g un`til they have nearly or quite parted with their heat by radiation, heating' currents of air, which, being in constant circulation, are drawn from the licor and carried upward through the stove,- and are there discharged in a highly-heated condition.

The invention consists in t-he peculiar construction of the various parts, their various combinations, and their operation, as more fully hereinafter described.

Figure l is a vertical central section ot' my improved stove. Fig. 2 is a horizontal section on the line 2 in Fig. l. Fig. 3 is a like View on the line 3 in Fig. l. Fig. 4 is a plan `view of the top. Fig. 5 is a plan of the bottom.

In the accompanying drawings, which form a part of this specitication, A represents` the` shell ot' the stove, B the bottom plate, and C the top plate thereof. A series ot' tubes, D, pass through the top and bottom immediatelyT outside of theI shell and open to the air above and below the stove, said tubes being secured to said 'top and bottom plates in any convenient manner, and with tight joints.

' E is the ash-pit, upon the top of which is supported the circular and flaring tire-pot F and the grate Gr. These members may be supported in any desired way.

H are a series of larger tubes enclosing the tubes D, opening at their lower ends into a chamber, I, (in which is suspended the magazine or feeder T,) and into the chamber4 J at their upper ends. This chamber is formed by the top plate, C, and the plate K and the circular wall L. The chamber I is formed by the shell A, the lower ring, M, base-plate B,

and liat ring N, which supports the lower ends of the tubes H and the shelLA. The upper end, 0, of the feeder llares to one side, as

shown in Fig. 1, to receive fuel through the i opening P in the plate K and the hole Q, in the plate C, the latter hole being provided with a removable cover. t

R is the exit through which the products of combustion pass to the chimney-liuc, and S a sliding damper affording direct communication between chambers l and J when a direct` The open top ot' the maga- (Not obtained from the tubes, as well as from the wall of the stove which they surround.

What I claim as my invention isl. A heating-stove having the interior shell, A, forming the combustion-chamber', in combination with the exterior lire-tubes, H H, each tire-tube H surrounding an air-tube, D, which passes entirely through the stove, whereby direct radiation is obtained from the .shell,from the lire-tubes, and from the air-tubes, substantially as described. l

2. ln a heating-stove, the combination of the shell A, bottom B, top C, chambers I J, grate G; ash-pit E, feeder T, and the air-pipes D D, each air-pipe passing entirely through a separate lire-tube H outside of the shell, substantially as described.
