Title: Improvements in or relating to escapement mechanisms
IPC: G04C5/00
Filed: 1943-08-06
Abstract: 568,423. Automatic control systems. WATFORD ELECTRIC & MANUFACTURING CO., Ltd., and VUILLE, B. A.. Aug. 6, 1943, No. 12758. [Classes 35 and 38 (iv)] [Also in Groups XVIII, XIX and XXXVIII] A shaft is driven jointly by a constantly. acting torque, e.g. a disc-type induction motor 313 and a motor of the type in which the rotor is a toothed disc of magnetic material acted on. by a pair of magnets, the poles of which are alternately opposite teeth and spaces as the disc rotates, the members of the pair being energized alternately so as to give an escapement effect. The drive may be used in the receiver of remote control apparatus or clock. In the application described, the mixed drive continues for a predetermined period to advance the arm of a variable resistance geared to the shaft, after which the step-by-step magnets are disconnected and the resistance is driven on to its normal position by the motor 313 alone. The impulses are derived from cam-operated contacts driven at at speed depending on an electrical load and the resistance has the same function as the resistance RL in Specification 545,150, i.e. it acts jointly with a resistance RT varied uniformly with time throughout a measuring period to unbalance a self-balancing bridge in accordance with a comparison of the average load with a standard load and so cause, if' necessary, an automatic adjustment of the actual load. An identical mechanism may be used to drive the resistance RT. Detailed operation. The induction motor comprises two shaded-pole magnets 314 normally fed from an A.C. source through a resistance and a braking magnet 316 normally fed with D.C. The escapement motor has four magnets energized two at a time and arranged so that the poles of one pair are opposite spaces in the rotor disc when the poles of the other pair are opposite teeth. In operation, one pair is weakly and the other strongly energized in accordance with the condition of a relay 329 which receives impulses from a contact LIG at a rate depending on the instantaneous value of the load to be controlled. As the shaft advances, it drives the arm of a resistance R36 through a train of gearing. At the end of a, metering period, a momentary operation of contact 337 energizes 326 which locks, disconnects the brake magnet and the magnets of the escapement motor and shunts the resistance in the circuit of the induction motor. The resistance R36 is thus driven rapidly on to its normal position. Shortly before this position, cam-operated contacts connect up the brake and escapement-motor magnets and at the normal position 326 is shunted out. The relay 329 may be replaced by a relay, Fig. 2, having two windings 365a, 365b and a steel armature carrying a mercury switch.
