STOVE-DANIPER.
SPECIFICATION forming part of Letters Patent No. 623,417, dated April 18, 1899. Application filed September Z3, 1898. Serial No. 691,678. (No model.)
To @ZZ whom, t may con/067%:
Be it known that we, ANTON OHNEMUS and HENRY SNNER, citizens of the Unit-ed States, residing at the city of Quincy, in the county of Adams and State of Illinois, have invented certain new and useful Improvements in Stove-Dainpers, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.
Our invention relates to that class of dampers that are intended to be used more especially in cook-stoves to regulate the ovendraft and the blades of which are adjustable on their stems, so as to provide for a more or less extension of the stems, while the blades are situated opposite the draft-openings of Jche stoves.
The object of our invention is to make such a damper in a manner that there will be a close iit between .the parts to effectually prevent the passage of air when the damper is closed and also to prevent the warping of the stein of the damper, while the device as a whole is at the same time inexpensive, durable, and strong.
Our invention consists in features of novelty hereinafter fully described, and pointed out in the claims.
Figure I is a perspective view of our iniproved damper in open position. Fig. II is a like view showing the damper in closed position. Fig. III is a transverse section taken on line III III, Fig. II. Fig. IV is a detail longitudinal section taken on line IV IV, Fig. II. Fig. V is a detail elevation with the parts detached.
l represents the stem of the damper, and 2 the blade. The main portion of the stem is of oval shape in transverse section and has a broad backv 3, sloping sides 4, and a narrow front 5 extending the greater portion of its length. One end of the stem is turned to form a handle 6. The back of the blade iits against the back of the stem and is held thereto by ears or lugs 7 on the blade and by ears or lugs 8 on a plate 9, that fits in a recess l0, that is formed in the central part of the blade. rlhe plate is held to the blade by means of a bolt ll, and its inner edge is notched at 12 to receive one of the ears 7 on the blade. The upper and the end walls of the recess l0 slope inwardly from the outer surface of the blade, so that when the bolt ll is tightened to cause the ears 7 and S to engage the stem the inner edge of the plate will be p ressed against the back of the stem, and a tight close fit will be effected between the walls of the recess and the plate, the result being a practically airtight connection between the blade and the stem. The ears are formed to iit the sloping sides of the stein, and the blade is thus movably held to the stem and can be adjusted thereon by loosening the bolt, as will be readily understood.
By forming the stem without grooves and by clamping the blade firmly thereto throughout the entire length of the latter the stem is not liable to become warped by excessive heat.
IVe claim as our inventionl. Adampercomprisingastemof oval shape in transverse section and having a broad back, sloping sides and a narrow front, a blade having ears engaging one side of the stem, a plate having ears engaging the other side of the stem, and a connecting-bolt substantially as described.
2. A damper comprising a stem of oval shape in transverse section having a broad back, sloping sides, and a narrow front, a blade having a recess with sloping walls, and provided with ears engaging one side of the stem, a plate iitting in said recess, and having ears engaging with the other side of the stem, and a connecting-bolt; substantially as and for the purpose set forth.
3. In a damper, the combination of a stem having sloping sides, a blade having a recess with sloping walls and provided withl ears engaging one side of the stem, a plate fitting in said recess and bearing against the sloping walls thereof and having ears engaging the other side of the stem, and a connecting-bolt; said plate being notched to receive one of the ears on the blade so that its inner edge will rest against the back of the stem, substantiallyas and for the purpose set forth.
