[ 6215 14 to the battery. The light armature 5 will be attracted by a feeble current, bringing the spring 3 in contact with screw 1, shunting the commutator, which will be moved away from its contact with the hand the mechanism of the instruments. The armature 11, attracted by by magnet M1, brings the spring 9 in contact with the screw 7, dividing the current, which pa es through the line L2, magnet Ms of the intermediate, magnet M3 of the receiver to the base of both instruments, and through the lever 13 and spring 14 to the battery. The armature of the magnet M3 is attracted, carrying the fork or pallets which propel the wheel W, and also, by means of the pin 18, pushes lever 15 so that it strikes the adjustable screw in lever 13, throwing it away from its contact act with spring 14, breaking the circuit, and allowing the instruments to return to their normal position. of the instrument is an electric contact-point carried on an insulated arm. When contact is made by a movement of the index, a current is established, which goes to the receiver and sets in motion there a train of mechanism which moves a dial-needle or registering-pen in the same sense as the motion of the original needle of the transmitter. When this has been effected, a return current is set up, which moves the electric contact-points of the transmitter a distance of one scale-division away from their position of contact with the needle, and all the other electrical parts are restored to their original condition. The instrument is then in readine for another change in the actuating instrument. Three wires between the receiver and transmitter is the smallest number by which the re quisite operations can be effected. This electrical registering apparatus is adapted to transmitting time, or the by an index. - Acoustic telemeter, an apparatus for deindications of any instrument whose changes are shown term in ing a distance by the time occupied in traversing it by the sound of a detonation. telemetric (tel-e-met'rik), a.
