Description
UNITED STATES PATENT OFFICE.
J ULIEN H, THAYER, OF GOLD HILL, NORTH CAROLINA.
IMPROVEMENT IN TREADLE-MOTIONS.
Specification forming part of Letters Patent No. 155.553, dated September 29, 1874; application filed July 25, 1874.
To all whom it may concern:
Be it known that I, J ULIEN H. THAYER, of Gold Hill, in the county of Rowan and State of North Carolina, have invented a new and Improved Treadle-Motion, of which the following is a specification:
The invention will first be fully described, and then pointed out in the claim.
Figure l is a side elevation of my improved treadle-motion, and Fig. 2 is a plan view.
Similar letters of reference indicate corresponding parts.
A is the heel portion, and B the toe portion, of the treadle. They are both pivoted to the axis 0, usually employed for a treadle, to be worked by rocking the foot at the ankle. The heel part has an arm, E, extending about as far as the toe-piece, and having the usual connecting-rod F for turning the crank-shaft connected to it, while the toe-piece has a rigid arm, G, rising up by the side of the connecting-rod to its middle, or-a little above, and connected at its upper end to connecting-rod F by a short connectingdink, H. The upper end of the arm G swings forward and backward across the connecting-rod F, and delivers the pressure of the foot on the toe-piece against it transversely at the time it is passing its centers, thus carrying it past the centers. As represented in the drawing, Fig. 1, the pressure on the toe-piece will push the connecting-rod F to the left, off its center, and turn the crank-shaft to the right, and, as the crank and connecting-rod rise up to the upper center, the arm G will swing across to the left-hand side and press the rod F to the right, thus continuing the action in the same direction.
By changing the link H so that its connection with the arm G is lower than With the rod F-say, at I and J-its action will be re versed, and the driving-crank will be turned in the other direction.
The apparatus is alike applicable to footlathes, sewing-machines, and all other light foot-power machines, and it may be used for a double or single foot power.
I am aware that a double crank, two pitmen, and two wrist-pins have been employed, but my object is to adapt this treadlemotion to old sewing-machines.
What 1 claim is The combination, in a sewing-machine, with a single crank-pitman, F, of the heel A, having arm E, and the toe B, having arm G and end link H, as shown and described, for the purpose specified.
JULIEN H. THAYER.
