SPECIFICATION forming part of Letters Patent No. 428,129, dated May 20, 1890.

Application filed October 25, 1889. Serial No. 328,173. (No model.) l

To all wiz/0771, it may concern:

Be it known that I, DAVID L. OsBORN, of Kansas City, Jackson county, Missouri, have inven Led certain new and useful Improvements in Stove-Pipe Dampers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

My invention consists of a new and improved damper and ventilator to be applied to stoves, furnaces, boilers, and heating ap paratuses, whereby the heat, draft, and ventilation may be regulated as desired and by will of operator, of Which the following is a full, clear, and exact description.

My invention consists of an improved device and arrangement for regulating the heat, draft, and ventilation by means of two valvesthe main and auxiliary valve, the main valve and its relative adjustments so arranged with its relative connection that it operates the auxiliary valve in its movements and adjust'- ments, as hereinafter described.

First. The valves are arranged in their relative position in thev smoke pipe or flue so as to admit and allow the valves to oscillate in and out as desired. Second. The valve-seats are created and formed by removing va circular piece, the size being one-half of the diy mension of the circumference of pipe. Third.

Main valve is formed from a piece of iron one-half inch larger in diameter than the incision in the smoke-pipe, and soarranged in its construction as to allow one half of the valves to be inserted in the opening in smokepipe and to rest upon its seat on or within the side of the sm0ke-pipe, and the other half to rest upon its seat on the outside of smokepipe, which device effectually closes the incision in pipe resting upon its seat when closed. Fourth. rlhe main valve is hung or hinged at its diameter upon pivots to the center of opening or valve-seats, and is sol secured as to admit the valve to open and close in its oscillating movements. Fifth. The auxiliary valve is arranged, placed, and secured above the main valve in smokepipe, and its connections are adjusted to receive the reciprocative movements with the movement of the main valve. Sixth. The auxiliary valve is formed fronra piece of iron cut to the radius of the pipe it is to perform its work. Seventh. The auxiliary valve is hung and hinged upon a rod passing through the Vauxiliary valve at the center of smoke-pipe and so arranged as to stand upright or vertical. Eighth. Projecting arm is then secured to the auxiliary valve at its center and projects out one-half of the radius of the smokepipe, or equal to three-fourths of diameter of smoke-pipe. Ninth. The projecting arm of auxiliary valve hangs downward and is so adjusted to the main valve that the movement of the main valve is transmitted to the auxiliary valve in its relative position. lVhen the main valve is closed, the auxiliary is open, and, vice versa, main valve open, auxiliary valve closed. Tenth. The device and arrangement of the connecting-rod that joins and unites the two valves-the main and auxiliary valve-is formed by connecting-rod secured or toggled to the projecting arm of auxiliary valve, and then passes downward, the auxiliary remaining upright, or vertically passing through a seat formed by a bracket secured to the main valve to pass upward and downward on the connecting-rod, which transmits its motions to the auxiliary valve. f

Referring to the drawings by letter, Figure l is a perspective view of my damper located in a short section of pipe. A is the pipe. E is the bearing of the rod that holds the aux iliary valve in position in the pipe. Gis the front portion of the damper. `a is the handle by which the damper is opened and closed. d is the head of the pivot, to which arm B (seen at Fig. 2) is connected to the damper. F is a seat or hinged joint on which the damper gets its oscillating movement.

Fig. 2 is a sectional view of my invention, showing the interior arrangement of its different parts; D, an oscillating damper; E, a rod passing through the center of the pipe, on which the auxiliary damper operates. C is an extended flap, hinged at b to arm B, connecting the two dampers together.

Fig. 9 is the upper portion of the damper lapping over the cutaway portion of the stove-pipe when in a closed position; Fig. 10, the lower portion of the pipe cut away, the
