Abstract
525,644. Knitting-machines. BRITISH THOMSON-HOUSTON CO., Ltd. Feb. 24, 1939, No. 6192. Convention date, Feb. 25, 1938. [Class 74 (ii)] [Also in Group XXIV] In a Cotton knitting-machine, an electric motor 1 drives the main-shaft 6 of the machine through a two-speed countershaft gear 5, the doubleclutch k of which is controlled electromagnetically by a switch 9 actuated automatically by a cam-chain 10 whereby a temporary reduction in speed is obtained during the reduction process. The double-clutch k is actuated by a fork g, drawn by a spring 8 into the reduced drive position shown, and moved to the direct-drive position when a solenoid 7 is energized by the closing of the switch 9. The working speed of the motor 1 is controlled by means such as a rod 2, chain or belt, extending over the entire length of the machine, and serving first to close relay contacts 3 to start the motor, and then to adjust a resistance R in the rotorcircuit to vary its speed. The motor 1 is a stator- and rotor-fed three-phase shunt commutator machine. An independent reduced speed for plaiting may be provided by an additional electromagnetic device which moves the motorcontrolling rod 2 against an adjustable stop.
