Twelve lamps may be arranged in three circuits, every fourth lamp being in the same circuit. The different circuits contain pairs of spring fingers l arranged round a disc g which inter- mittently turns through the angle between the pairs so that a pin h upon it presses each pair in succession Alternatively, the pairs of fingers may be arranged over a drum o, Fig. 4, upon which there is a triangular thickening p. Escapements.-The disc or drum is in a train ending in an escape-wheel d having two pins e, f which escape from a bent vibrating arm c. The arm is either operated by an electromagnet b, or by a cam, there being a clock to make periodic coutacts to drive the cam.
