Letters Patent No. $7,221, dated February 23, 1869.

IMPROVEMENT IN DAMPERS.

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

To all whom it may concern:

Be it known that I, L. O. TABER, of Eaton, in the county of Madison, and State of New York, have ina stove, or stove-pipe, a damper which will open itself when there is more fire than is required, and which will close itself when there is less fire than is required, admit-ting air to the flue or pipe when open,'tliereby checking the draught through the fire, and when closed, causing the draught to pass through the fire.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

I construct my improved damper as follows, viz

I apply, to the back boiler-hole of .a'cook-stove, a rim, A.

'B is a cover supported upon its pins. One side of said cover is enough heavierthan the other, to open it, as shown in the drawings, figs. 1 and 2.

Under the heavy side of said cover, I apply the long arm of lever E, and to the short arm of said lever, I apply a brass rod,.F, partly encircling the rim A. One end of said rod is secured permanently to rim A at G.

To the opposite end of rod F, I apply a nut, H, for the purpose of tightening-or loosening said rod, by means of which the damper or cover may be so .set,

or adjusted, as to admit any desired amount of air.-

When the action of the damper is not needed, it may be fastened by means of the button 6.

By the foregoing description it will beseen that my improved damper is only applicable to a stove back of the fire. v

The damper-lid will open by its own grayity when uncontrolled, but by the united action of the lever and the brass rod, it is held closed, or partially closed, as adjusted by the thumb-screw, except when said rod is expanded by heat.

In Figure 5 my improved damper is shown as applied to the boiler-hole of a stove.

In Figure 6-it is applied to an opening, cut for the purpose, in the stove-pipe. It may in like manner he Witnesses L. I. WHITE, A. W. Monse.
