WILLIAM H. MYERS, OF OREGON, WISCONSIN, ASSIGNOB. OF ONE-THIRD OF HIS RIGHT TO E. HENRY OSBORN AND ONE-THIRD TO JAMES M.
FOX, OF SAME PLAcE.
IMPROVEMENT IN SEWING-MACHINE MOTORS.
Specification forming part of Letters Patent No. 176,036, dated April 11, 1876 application filed April 3, 1876.
To all whom it may concern:
Be it known that 1, WILLIAM H. MYERs, of Oregon, in the county of Dane and State of Wisconsin, have invented a new and valuable Improvement in Sewing-Machine Motor; and I do hereby declare that the following is a full,
' clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of reference marked thereon.
Figure 1 of the drawings is a representation of my motor attached to a sewing-machine table, and Fig. 2 is a vertical sectional view of the same. Fig. 3 is a detail view thereof.
This invention has relation to motors which are especially designed for driving sewing-machines, watchmakers lathes, and other light machinery; and the nature of my invention consists in a vertically-adjustable pendulum, which is actuated by clock mechanism and a cam-wheel, in combination with a treadle for stopping and starting the motor, and with a device which will stop the movement of the pendulum when the foot-is removed from the treadle, as will be hereinafter explained.
In the annexed drawings, A designates the frame of the improved motor, which is secured to a table-top, B, and G designates a balancewheel, to the wrist-pin of which the lower end of a toggle-lever, I), is applied. The upper arm of the toggle has pivoted to it a pitmanrod, to, which is adjustably pivoted to a pendulum, E, having its fulcrum at b. This pendulum is composed of two parts, 0 c. The part 0 receives between its upper bifurcated end the corrugated .edge of a cam-wheel,-F, which is geared with the train of wheels above referred to. The rotation of the wheel F transmits avibratory motion to the pendulum E, and this pendulum transmits rotary motion to the fly-wheel through the medium of the pitman-rod a and toggle-joint D. The lower section 0 of the pendulum, or that section which has the weight w attached to it, is free to rise and descend through two cars, jj, formed on the pendulum-section 0, and to the section 0 h a string or chain, 70, is attached, which is carried over a pulley, 19, and attached to a treadle, G. J is a stop-flange, which is curved, as shown, and located beneath the loaded end of the pendulum rod 0 in such relation thereto that when the foot of the operator is raised from the treadle Gr the vertically-movable section of the pendulum will be depressed by its own gravity, and stopped by contact with the stop-flange J.
When the treadle G is depressed, the pendulum section is raised and freed from the flange J, which allows the pendulum to be'vibrated by the cam-wheel F.
It will be seen from the above description that the fly-whecl (J can be started or stopped at pleasure by simply depressing the treadle or raising it, and that the power obtained is derived from a springer a weight acting through the medium of a train of wheels, which can be multiplied to any desired number.
What I olaimas new, and desire to secure by Letters Patent, is-
1. In a motor for sewing and other machines whose prime force is derived from a spring or weight acting through a train of wheels, the sectional pendulum E, stop-flange J, pitmanrod on, toggle-joint D, and treadle-chain 70, combined and operating substantiallyzin the manner described.
2. In a motor for sewing and other machines whose prime force is derived from a spring or weight acting through a train of wheels, the sectional pendulum E, pitman a, toggle ioint D, and treadle-chain k, combined and operated substantiallyin the manner described.
In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.
WILLIAM H. MYERS.
