Abstract

23,919. Stockert, J. Nov. 30. Drawings to Specification. Telegraphs. - Relates to operating-mechanism and circuits by which a number of keys at a transmitting- station can operate a number of magnets controlling the action of the levers of a type-writer. The keys are connected to a series of rapidly-acting "self-interrupters" by means of a common relay and " interrupter." The relay tongue is in the main circuit, and the " inter- '' rupter " is in a local battery circuit. The main battery is divided, one portion being put to line immediately on the depression of a key, and the remaining portion being added as soon as the '' self-interrupters " have worked back step-by-step to the first "self-interrupter." The receiver is provided with a similar set of step-by-step rapidlyacting "self-interrupters," two relays, one for weak and one for strong currents, and an interrupter. The break relay and interrupter connect up the " self-interrupters," which act in agreement with the transmitter "self-interrupters" and arrive at the desired electromagnet at the time when the strong current can actuate the second relay controlling the operating local circuits for the electromagnets,
