JAMES R. YEMAN, OF SENECA FALLS, NEW YORK, ASSIGNORIOF ONE-THIRD TO SAMUEL T. SHARP, OF SAME PLAGE.
AUTOMATIC TREADLE FOR SEWING-MACHINES.
SPECIFICATION forming part of Letters Patent No. 263,644, dated August 29, 1882.
' Application tiled May 17, 1882. (Model.)
To'all whom t may concern Be it known that I, JAMES B. YEMAN, of Seneca Falls, in the county of Seneca and State of New York, have inventednew and useful Improvements in Treadles, of whichthe following, taken in connection with the tgure, in perspective, in the accompanying drawing, is a full, clear, and exact description.
This invention relates to treadles adapted zo more particularly for operating sewingfmachines, and has reference to the class ot'treadles which are mounted on the two ends ofa treadle- Vbar pivoted at its center. l
rEhe invention consists in a novel construction and combination of parts, as hereinafter fully explained, and specifically set forth in the claims.
A represents a vibratory frame,composed of two parallel bars, united at the center by a fixed zo crossbar.
B B designate the treadles, pivoted at their ends directly to the frame A, respectively, at opposite ends thereof.
The frame A is pivoted at its center on a stationary supportingbar, D, having verti-` cally-projecting lugs or shoulders at the outer sides of said frame, through which lugs passes a set-screw, C, having a conical end engaging `the side ot the frame A. This arrangement 3o admits of taking up the wear ot the pivotal connection ot' the frame A, which constitutes the treadle-bar, and also affords the utmost convenience for attaching and detaching the said treadle-bar to and from the machine when desired. The treadles B B being connected to the frame A in a similar manner, imparts to them the same advantages.
Having described my invention, what I claim as new, and desire to secure by Letters Paten t, lS- 10 1. In combination with a stationary central support, d, the vibratory frame A, composed of two parallel bars united at the center by a rigid cross-bar, and pivoted thereat on the support d, and the treadles B B, pivoted at their ends directly to the ends of the frame VA, substantially in the manner described and shown.
2. The vibratory frame A, provided with a central tie and with the pivoted treadles B B, as shown, in combination with the stationary central support, D, provided at the outer side of the frame A with vertically-projecting lugs, and set-screws C, inserted through said lugs and having conical points engaging the side of the frame A, substantially as described, for the purpose set forth.-
Dated Seneca Falls, New York, May 13, A,
