SELF-REGULA'IV'ING DAM PER.
Specification forming part of Letters Patent No. 48,291, dated June 20, 12565; antedated March 15, 1865.
To all whom it may concern:
Be it known that I, CHARLES H. LAVIS, of Philadelphia, in the county of Philadelphia, in
the State of Pennsylvania, have invented a new and Improved Self-Regulating Damper for stoves, furnaces, smelting-furnaces,and the like, which require a well-regulated draft; and
' I do hereby declare that the following is a full,
cle'ar, andexact description thereof', reference being had to the accompanying drawings, and to the letters of reference marked thereon.
My invention consistsin regulating the damp-A out the several Views.
A is a square drum, (ofany metal,) in which the damper B, which vibrates with the rod C, is fitted. The rod C passes through the drum A and bears on its sides at c c. It is placed as near the upper corner or angle, d, as may be convenient for its proper working. One end D ofuthe rod C is bent to any angle (in this case to a right angle.) This end D has a screw cut on it, on which is screwed the balance E.
Circular holes F F are out on opposite sides of the drum A, sothat the working ofthe damper B may be seen. These holes are covered with isinglass, which is kept in place by the flaps e c.
Small holes ffffare punched in the damper B, to allow the gasto escape while the damper is closed.
The flanges Gr G are to receive the stovepipe to which the drum A is fitted.
The damper B, hoes c c', end D of the rod C, and balance E form a lever of the first order. rPhe holes c c are the fulcrums, the damper B the weight, and the balance E the power. The weight E can be so adjusted that a perfect equilibrium will exist and the dam'per B be entirely closed. It can also be adj usted by screwing the weight up or down that any degree of draft can be obtained. l i
What I claim as of my invention, and desire to secure by Letters Patent, is
Y The drum A, the damper B, the rod C, the
Y screw D, and the balance E, constructed and operated with reference to each other, and for Vthe purpose and in the manner as herein shown and described.
CHARLES H. LAVIS.
