[Class 38(v)] [Also in Group XXXVIII] The balance wheel 9 has a magnetic part 14 which cooperates with a magnet 15. It is normally latched by an arm 21 which is moved clear by a magnet 23 when the device is switched on. At the same time, magnet 15 is energized and the magnetic portion 14 is attracted. As a result, contacts 16 are operated momentarily energizing relay LAN which locks up and cuts a resistor 25 and the contacts 16 into the circuit of the driving magnet which therefore releases the balance wheel when the springs open. During the return movements, the springs 16 are not operated but on each forward stroke they give an impulse to the magnet to keep the device running. Impulse springs 8 also are actuated only during the forward movement. Their position is adjustable along the arc 24 to compensate for variations in the time necessary to bring the device into action owing to manufacturing differences.
