IMPROVEMENT IN DAMPERS.
Specification forming part of Letters Patent No. 154,798, dated September 8,1874 application filed August 1, 1874.
To all whom it may concern:
Be it known that I, JOHN G. KOPPING, of Clinton, inthe county of Clinton and State of Iowa, have invented a new and valuable Improvement in Stove-Damper and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 is a front View of my perforated spring-holder, and of the hooked end of the damper-shaft applied to a section of stovepipe. Figs. 2 and 3 are plan views of the same, and Fig. 4 is a sectional view. is a plan view.
This invention has relation to stove-pipe dampers; and it consists in a damper which is composed of two hinged semicircular sections constructed with hooks to receive arms on the damper-rod, in combination with a hook on one end of said rod and a perforated springholder, whereby a self-regulating damper is obtained which can also be regulated by hand,
.as will be hereinafter explained.
Fig. 5'
loosely, as indicated at c c. E E are two arms, which are secured to the rod 0 in the center of the pipe A, and e is a tongue, which is also secured to the rod 0, the object of which tongue is to lift one of the damper-sections over and upon one of the arms E in adjusting the said sections from the position shown in Fig. 5 to that shown in Figs. 2 and 4, in which latter position the arms E hold the sections stifiy together by engaging with the hooked portions 01. When the damper-sections D D are detached from the arms E, and the hook at on rod 0 is engaged with the lowermost hole in spring B, the sections will hang freely, and will be spread out more or less, according to the force of the draft. I thus have a self-acting damper. By turning the sections over and adjusting the arms E under the hooks d d the sectionswill be held rigidly together in the same plane, and may be adjusted and set at any desired angle like any well-known damper.
The perforations b through the damper-sections D D are for the purpose of allowing the escape of gas when the sections are in the closed position shown in Fig. 2.
What I claim as new, and desire to secure by Letters Patent, is-
The damper-sections D D, hinged to a hooked rod, 0, in combination with arms-E, hooks d, and a perforated spring, B, substantially as described.
In testimony thatI claim the above I have hereunto subscribed my name in the presence of two witnesses.
JOHN GEORG KOPPING.
