Fig. 6 shows a receiving instrument R, with a vibratory circuit-breaker _v_ attached. The light spring-lever _v_ overlaps the free end of the steel reed A, and normally closes a local circuit, in which may be placed a Morse-sounder or other telegraphic apparatus. When the reed A is thrown into vibration by the passage of a musical signal, the spring arm _v_ is thrown upwards, opening the local circuit at the point 5. When the spring-arm _v_ is so arranged as to have normally a much slower rate of vibration than the reed A_{1}, the local circuit is found to remain permanently open during the vibration of A, the spring-arm _v_ coming into contact with the point 5 only upon the cessation of the receiver’s vibration. Thus the signals produced by the vibration of the reed A are reproduced upon an ordinary telegraphic instrument in the local circuit. Fig. 7 shows the application of electric telephony to autographic telegraphy. [Illustration: Fig. 7.] T, T´, &c., represent the reeds of transmitting instruments of different pitch, R, R´, &c., the receivers at the distant station of corresponding pitch, and, _r_, _r´_, &c., the vibratory circuit-breakers attached to the receiving instruments, and connected with metallic bristles, 21, resting upon chemically prepared paper P. The message, or picture, to be copied, is written upon a metallic surface, F__0_, with non-metallic ink, and placed upon a metallic cylinder 7, connected with the main battery B; and the chemically prepared paper P, upon which the message is to be received, is placed upon a metallic cylinder connected with the local battery B´ at the receiving station. When the cylinders at either end of the circuit are rotated in the direction of the arrows—but not necessarily at the same rate of speed—a _fac simile_ of whatever is written or drawn upon the metallic surface F__0_ appears upon the chemically prepared paper P.
