Cyclopedia of applied electricity : a practical guide for electricians, mechanics, engineers, students, telegraph and telephone operators, and all others interested in electricity . 23 Receiver, Showing Connection Between Coherer Relay, Morse Register, and Collector. Fig. 47. pulses per given period of time; these waves actuate different re-ceivers adjusted in accordance with the pre-arranged time the key closes the circuit of the battery 1 and the electro-magnet 2, the armature of the latter releases a clutch on the disc3 from the pin 4; the disc is rotated by a frictional shaft 5 makingfive revolutions per second. Every revolution of the disc causesthe pin 0 to close the circuit including the l)attery 7 and the elec-tromagnet 8; the disperser proper consists of a disc having attachedthereto four hundred straight steel springs 9, their free ends passingthrough a radial slot in the upper revolving disc 10; a brass ring 11serves as a guide for the spring points and when the disc revolves 367 38 WIRELESS TELEGRAPHY.

As the disc rotates, tlje springs make con-tact with projections extending around the frame at certain prede-termined intervals and in this way waves of ]ire^^(ril)ed fivijuencyare consequently emitted. AYlien these periodically emitted waves impinge upon the an-tenna of the receiving apparatus, Fig. 47, the coherer closes thecircuit of the relay magnets 23; and the tapper 24, and the collectormao-net 25 are brought into action. The mechanism of the eol-lector is exactly like that of the disperser and can therefore beinstantly converted into a disp
