IMPROVEMENT in sTovE-PIPE DRUMS.

Specification forming part of Letters Patent No. 47,833, dated May23, 1865.

.To all whom it may concern:

Be it known that I, JACOB B. HYZER, of the city oit' Janesville, county of Rock, and Sta-te of Wisconsin, have invente l a new and Improved Inode of' Constructing and Uperating a Heat-Radiator; and I do hereby declare that the followingis a full, clear, and exact descript-ion of the construction and operation of the same, reference being had to the accompanying drawings, making a part of this specication, like characters referring to like parts in each figure.

The nature of my invention consists, rst, in making a series of'holes through the radial plates used to partition heat-radiators, to partially turn the draft so that all parts ot1 the radiating-surfaces are equally heated and radiate the same amount of heat; second, in so constructing a heat-radiator having ascending aud descending flues ory an inner unconrined hot-air space that one central pipe and a'i ordinary damper serve all the purpose of inducting and discharging the smoke and iiame.

To enable others skilled in the mechanic arts to construct and operate a heat-radiator with my improvement, I will refer to the accompanying drawings, in which- Figure lis an elevation with a portion of the outer cylinder or case broken away. Fig. 2 is a vertical section cut centrally on the line ot' the damper-rod. Fig. 3 is a vertical section at right angles to Fig. 2. Fig. fl is a plan or top view or" the heat-radiator. Fig. 5 is a vertical section with a portion oi' the upper part cut away) similar to Fig. 3, showing a modification ofthe cross-fines and dampers.

I construct the radiator ot1 any convenient form or size, and from any suitable material, providing it with the appendages heretofore used-4to wit, an outer and an inner radiatingcylinder, A B, radial plates a and a', and an inner unconned hot-a-ir space, f. Centrally through the hot-air space j', I pass the smokeflue C, from opposite sides of which the crossiiues d and e are made to pass through the lower portion of the cylinder B into the space g between it and the outer case. When the cross-dues d and e are placed with reference to their altitude directly opposite to each other, as shown in Fig. 3, a damper bent in the form therein shown is required; but when the :dues

d and e are placed one above the other, as shown in Fig. 5, I use the plain straight damper therein shown.

In the space g between the cylinders, midway between the cross iiues, I put the radial plates a and a', partitioning the lower portion of the space, so that the heated air, flame, and smoke, dividing as they enter through the iiue d, must pass upward to the top of the radiator and over the radial plates a and a', and thence downward and through the iiue e into the central pipe, C, again. In the radial plates I make a series of holes or orifices, a, the objectof which is to allow enough of the heated air, smoke, and flame to pass through the radial plates to heatthose portions of the radiatingcylinders adjacent to the lower portions of thc plates, and so preventing the radiating-cylinders from being' unevenly heated, as heretofore experienced.

When in operation, turning the damper c to the position shown by the dotted lines c', Figs. 2, 3, and 5, secures `a straight, direct,

and full draft; but with it in the position shown in the drawings, the heated air, smoke, and flame pass through the lue'd into the space between the radiating-cylinders A B, thence over or through the radial plates a and a to the opposite side of the space, and thence through the flue e into the smoke-pi pe C, above the damper.

It will be seen that a radiator constructed as above described, with the inductive and discharge pipes forming one and the same iiue, secures the full draftof the ordinary pipe when desired, requires only one plain, cheap damper, and does not need to be supported, as the induction-pipe entering the radiator centrally from below supports it, thus avoiding the cost of constructing and the inconvenience of operating two dampers, and the difficulty of supporting the radiator'when the induction-pipe does not enter it centrally from below.

I apply my radiator both to furnaces andstoves. h

I am aware that ascending and descending iiues and an inner hot-air space, as also a straight flue regulated by a single damper, (to wit, the ordinary stove-pipe and dan1per,) have heretofore been known and used, and I do not claim them when used separately, but

only when combined as hereinbefere deseriba straight flue regulated by a single damper,

ed; but' substantially as described.

What I do elainnand which I desire to se- 3. Constructing` the radial plates With a eure by Letters Patent of the United States, series of orifices or holes, substantially as and isfor the purpose set forth.

1. A heat-radiator, when constructed and arranged substantially as herein described JACOB B' HYZER' and set forth. Witnesses:
