EDWARD HALL, 0F BEIIOIT, WISCONSIN AN D FRANC/ISU SEARL TON, ILLINOIS.

Letters Patent No. 102,114, dated April 19, 1870.

The Schedule referred to in these Letters Patent and making part of the same.

` drawings, which make part of this specification, and

in which- Figure 1 is a vertical central. section of our 'xn' proved stove-pipe shelf, heater, and damper combined, as attached to a stove-pipe.;

Fi urc 2 is a to) view of the stovei e showin r e a the damper; and

Figure 3 is detached view of the damper. Like letters of reference indicate like parts in the several figures.

Our invention consists in a hollow stove-pipe shelf` having a detlector, above and below which a series of openings are formed in the stove-pipe, which, in coinbination with a damper in the latter, allow the heat to pass up through the stove-pipe or forceit through the hollow stove-pipe shelf, according to the position given to the damper. A in the drawings represents a stove-pipe, on which is formed a funnel-shaped circular drum, B, over which a l'ul or shelf, C, tits snugly, the drum and lid together forming a hollow receptacle.

About midway between the lid or shelf Gand the drum B, where the latter is formed on or attached to the stove-pipe, is a detlecting funnel-shaped shelf, D, also secured to the stove-pipe, which latter, at a suitable distance above and below this deiiector D, is provided with series of openings I) c, between which, again, a damper, E, is suitably pivoted in the storepipe.

This damper E is operated by a rod, e, which passes out through the side of the drum B, and it has at one part of its circumference a small portion cnt out` to allow it to pass a projection, f, on the nside'of the stove-pipe, while at the opposite side of its circumference it is provided with Va weight, g, which will keep the damper either in a vertical position or in a horizontal one by resting upon the projection f.

lVheu the damper is in a horizontal position the products of combustion can not escape through the stove-pipe directly upward, but are forced to pass through the openings b, under and around the de- Hector D, and into the stove-pipe again through the openings c, when -they are allowed to escape upwardly'. When the damper is open the products of combustion are not forced to pass through the hollow shelf', as above' described, but the draught carries them directly upward. Thus the shelf', if used as such, may be heated to any desirable degree, suicient to boil water placed in a vessel on it. If desired to use it as a heater the damper is closed, when the products of combustion will heat the entire chamber or drum by passing through it.

In iig. 2 the damper is shown in the act of being turned from the right to the left, to close it.

Having thus described our invention,

What we claim as new, and desire to secure by Letters Patent, is

1. The combined stove-pipe shelf, heater, and damper, when constructed substantially as herein described, and operating with the deector D and lid C, substantially as herein set forth.

2. In a stove-pipe shelf, the funnel-shaped deflector D, when attached to the stove-pipe and independent oi' the drum, substantially as herein described.

3. In a hollow stove-pipe shelf, heater, and damper combined, the combination of the damper E and upper and lower openings c b in the stove-pipe within the hollow shelf, substantially as described.

4. The'combination ofthe drum B, lid C, deiiector D, damper E, and stove-pipe A, provided with lower and upper openings Z1 c, constructed and operating substantially as described.
