Title: Improvements relating to the operation of electrically driven textile machinery
Inventor: HOLT FREDERICK BRERETON
IPC: D01H1/244
Filed: 1950-06-23
Abstract: 689,323. Controllers. METROPOLITANVICKERS ELECTRICAL CO., Ltd. June 13, 1951 [June 23, 1950], No. 15783/50. Class 38 (iii) A hand control lever 1 for a textile machine having an individual induction motor drive is rigidly coupled to a lever 5, and, when the lever 5 is moved towards the left, it disengages a striker arm 9 for switch 10 so energising the driving motor. After a time delay, during which a spring 14 is compressed, the movement of the control lever is transmitted through Bowden cable 13 to initiate release of a brake for the machine. Further movement of the hand lever will gradually release the brake until the lever approaches the limit of its travel wherein armature 21 is near to hold-on magnet 22, an arm 18 engages switch 20, and the brake is fully removed. The closure of switch 20 energises the magnet 22 so that the lever is held in this position against the action of spring 6. When a trip knob 2 is depressed switch 10 is opened to break the circuit of the hold-on magnet, de-energise the motor, and release the lever 5 to apply the brake. The machine may also be stopped by actuation of a push-button or other additional switch to de-energise the hold-on magnet. The hold-on magnet may be replaced by a solenoid-operated latch. Failure of the power supply may cause the automatic return of the control lever to the brake "on" position, or the lever may have to be manually returned to this position before the power supply can be re-applied. The Bowden cable may be replaced by hydraulic, electric, or other forms of linkage. An automatic arrangement in which the brake is gradually released at a pre-determined rate by power-operated means following the actuation of a start switch may be used instead of the hand lever control. The operating lever may be driven by an electric motor, for example.
