STOVEPlPE-DAIVI PER.
SPECFICATION forming part of Letters Patent N 0. 567,025, dated September 1, 1896.
d Application filed February 6, 1896. Serial No. 578,203` (No model.)
To MZ whom t may concern:
Be it known that I, HIRAM L. FERRIs, a citizen of the United States, residing at Osage City, in the county of Osage and State of Kansas, have invented certain new and useful Improvements in Stovepipe-Dampers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates to those stovepipedampers consisting of a hinged damper-lid and means for holding it in the various open and closed positions, and the objects sought to be accomplished are more perfect draft regulation, better ventilation, adaptability to all kinds of stovepipes, simplicity of construction, and cheapness of production.
Having these objects in view, the invention consists in certain improvements in the hinge connection between the damper-lid and the stovepipe and in improved means for holding the damper-lid in its various positions.
In the accompanying drawings, Figure l represents a perspective view of my complete invention as applied to an ordinary stovepipe and with the damper-lid open; Fig. 2, aside elevation thereof, showing the damperlid closed; and Fig. 3, a detail view of the hinge and friction-spring. l
Asection of an ordinary stovepipe is shown at A. A suitable opening, preferably rectangular in shape, is made in the stovepipe, and is covered by wire-netting l to prevent any of the solid products of combustion from escaping into the room when the damper is open. A rectangular frame 2 is fitted to the opening in the stovepipe and carries the damper-lid and connections, being provided with a projecting lip or catch 3 at its bottom to hold the damper-lid closed, as will appear hereinafter.
The damper-lid 4 is of the usual construction and is connected to the frame 2 by my improved hinge connection, now to be described. This hinge consists of a hinge-leaf 5, connected to'and projecting upwardly from the france2 at an angle of about forty-five nected to the leaf and passing looselythrough an elongated slot in the leaf 6, a suitable nut 8 being provided to hold the parts together. This construction permits the damper-lid to be lifted slightly and dropped into the catch 3 when it is to be held closed. It is also to be noted that the center of gravity of the damper-lidV is situated at one side and away from the stovepipe. Consequently when the damper is released from its catch it immediately swings open and remains so until closed. It is of course necessary to regulate the amount of opening of the lid, and for this purpose I provide an improved friction-spring. piece of spring wire or ribbon bent to form an open head 9 and neck 10, provided with a stricture 1l intermediate of its length. The friction-spring is placed astride the hingeleaves, so that the movable one 6 operates within the open neck and head of the spring when the damper-lid is opened, this spring having its extremities 12 and 13 fastened to the frame 2. The neck of the spring is adapted to pinch or grasp the hinge-leaf, so that the damper may be held open to any desired extent. Let it be assumed that the damper-lid is closed. The damper may be opened by slightly raising the damper-lid so that it is freed from its catch. Its tendency to swing open is resisted by the action of the friction spring, and the leaf 6, becoming wedged in the neck of the spring, holds the damper-lid open. As the damper-lid is opened still farther friction increases between the open neck and the leaf 6 until the stricture ll is reached, when it is greatest. This stricture preferably lies in the center of gravity of the damper-lid, and consequently thetendency is for the damper to remain open when this point is reached. The damper-lid can be opened still farther if desired, but it reaches the limit of frictional action of the spring when it leaves the open neck and begins to enter the open head 9. This open head is provided so that the damper-lid may be opened very wide when cleaning and repairs are necessary. After the hinge-leaf has This spring consists of a` IOO passed the stricture ll it is prevented from swinging closed of its own accord.
Having thus deseribed my invention, what I claim as new, and desire to secure by Letters Patent, is*
1. The combina-tion with a stovepipe provided with t draft-opening, of zt damper-lid for said draft-opening, a hinge-leaf pivotally connecting the damper-lid to the stovepipe, and a friction-spring having arms which bind upon the hinge-leaf, whereby the damper may be held in open position.
