Abstract
186,130. Fairweather, W., (Singer Manufacturing Co.). June 17, 1921. Clutches, friction; gearing for stopping and starting machinery.-In sewing and other small machines in which the mechanism for declutching the motor from the machine is arranged to cut in resistances into the motor circuit so that the motor runs at reduced speed during the idle period of the machine, a motor C is secured by housings 11, 12 on an outwardly projecting bearing-boss 10 of the main shaft 9. The shaft 16 of the motor carries a worm 17 meshing with a gear wheel 18 secured on a clutch disc 1 turning freely on the shaft 9. A hand-wheel 20 fast in the shaft 9 is clutched to the disc 19 by a ring 21 carrying pins 22 which slide in holes in the wheel 20 and are engaged by a pusher 24 to force the ring into contact with a loose ring 23 of compressed cork &c. which frictionally engages the disc 19. The' pusher is actuated by the engagement therewith of an adjustable stud 36 of anti-friction material such as oil-soaked hard wood mounted in a lever 34, pivoted on the frame and also carrying a brakeslroe 39. The lever 34 is connected by a link 42 to a lever 44 on a shaft 45 rotatable against the action of a spring by a treadle rod 48. Connected to the treadle rod bv a chain 57 is a rheostat arm 53 held by a spring 55, when the machine is at rest, on the uppermost of three contacts 54 so as to include in the motor circuit resistances r<11>, r<1>. When the treadle rod is depressed to start the machine, the resistances are successively cut out and immediately after the arm 53 meets the lowest contact the clutch is engaged. In a modified construction the motor is mounted on the standard of the machine arm within which the worm 17 and gear 18 are situated, and the driven clutch-member, directly actuated by the stud 36, carries a square-section ring of leather &c. engaging a conical driving- member.
