UNITED STATES PATENT OFFICE.
M.'DE ROY SPAULDING, or CHICAGO, ILLINOIS.
lMPRQVE-MENTIN TREADLES.
Specification forming part of Letters Patent No. 174.163. dated February 29, 1876; application filed November 30, 1875.
To all whom it may concern Be it lgnown that I, M. DE ROY SPAULDING,
lowing is a full description, reference being had to the accompanying drawings, in which.' ,Figure l is a top or plan view; Fig. 2, a side view.
cushion or pad to a treadle.
In the drawings, A represents a double treadle; B, the ears by which it ispivoted to or supported on a bearing bar or rod; 0, the arm for attaching a pitman or other connection; a, the rubber or elastic sections inserted into the body of the treadle, and bthe hole in which the sections are inserted. V
In theform shown the treadle is double; it may, however, be made double or single, as
The rubbers a are cut from cylindrical rubber strips, and are inserted by being pressed through holes b, which are rimmed out to enable the rubbers to be properly inserted,
jar in reversing the movement; that it prevents the foot from slipping, and that it gives a slight additional impulse to that given by the foot. My invention consists in applying an elastic Theform shown is an easy and durable way of applying rubber to a sewing-machine treadle, for which usethe form shown is designed; but the. elastic cushion may be applied to treadles for foot-lathes and other devices.
What-I claim as new, and desire to secure by Letters Patent, is as follows:
In a treadle, the elastic cylindrical sections a, inserted through the holes b, substantially as specified.
M. DE ROY SPAULDING.
