Title: Improvements in and relating to Electric Motor Control Systems.
IPC: H02P1/34
Filed: 1911-07-07
Granted: 1912-03-14
Abstract: 15,841. British Thomson-Houston Co., [General Electric Co.]. July 7. Master control systems.-Systems of motor control, in which a separate control relay carrying motor current is used with each resistance contactor, have an actuating-coil as well as a series coil for each relay. The invention is described as applied to the control of a threephase machine, and a pair of relays 4, 5, 6 cut out each step of resistance successively. To connect the stator to the mains, a switch 30 is closed and energizes a coil 4', the circuit passing between the mains 1, 2, via the interlock 21 on one of the main contactors The core of the coil 4<1> having lifted and bridged the contacts 7, the circuits of the coils 16, 18 are completed in parallel between a point a and the main 2. The contactors of these coils thereupon pull up, and they are followed by that of the coil 17, the circuit of which is completed by an interlock 22 on the core of the coil 18. The stator is then connected across the mains and the motor starts with full resistance in the rotor circuit. De-energization of the coil 4' by the interruption of its circuit at the contacts 21 allows the contactor to fall and join the contacts 8, when permitted to do so by the series coil 13. A circuit is then completed through a wire 31 and the pair of coils 4, and through a common return 32 and the interlock 19 to the main 2. Both contactors of the coils 4 thereupon pull up, and short-circuit one step of the resistance. The circuit of the coil 5<1>, which was completed on the operation of the contactor of coil 16 via the interlocks 28, 19, is thus broken, and the coil 6' is energized via the interlock 29. When the series coil 14 allows the contactor of the coil 5<1> to fall, the circuit of the coils 5 is completed and another step of resistance is cut out. The switching sequence is repeated for the final step.

The paper band passing from the roll N to the roll O and below the stamp is operated intermittently by the first part of the inward movement of the ticket carriage H, two rack teeth 14 on which oscillate a shaft 12 carried by the swinging head C to drive the bevel-gear 10, 11, 7, 8 and telescopic shaft 9 and through ratchet gear 3, 2 the take-up roll O. A gapped flange 15 on the shaft 12, acting in conjunction with a fixed pin 16, limits the oscillation of the shaft, and a spring detent 17 engages recesses in the flange to hold the shaft at its limits of oscillation for the rack to gear with the wheel 13 correctly. The moistening - roller 18 mounted in vertical slots in the sides of the carriage H and pressed upwards by spring plungers has its axles extended to. engage slots in cam-pieces 24 pivoted at 25 to the sides of the carriage and limited in its oscillation by pins 23 on the carriage sides engaging slots in the cams. On the inward movement of the carriage the paper band is first fed forward by the rack, the roller 18 then moistens the band extending below the stamp and round a stripping bar 30 carried by bent springs 32, so that the bent end portions normally lie flush with the stamp, and, finally, lugs on the carriage act against the bar 30 to move it into the position shown, and fixed pins 26 on the spring head depress the cams and therefore the moistening-roll. At this stage, the carriage is held by a spring-controlled pawl u and the head is swung to emboss the date and effect the copying. At the completion of the return swing of the head, a spring catch on the frame disengages the pawl u from the carriage, which then returns under the action of a spring, the spring-mounted bar 30 then traversing across the stamp to strip the paper band therefrom, and fixed pins 27 finally acting on the cams 24 to raise the moistening-roll into position for the next operation of the machine. A suitable spring device holds the cams 24, and consequently the moistening-roll, in the raised and lowered positions.
