Abstract: 303,499. Electrical Research Products, Inc., (Assignees of Clokey, A. A.). Jan. 5, 1928, [Convention date]. Synchronous movements; duplex telegraphs.-A synchronous telegraph system, as described in Specification 228,828, comprises switching means 10 at each station for setting apparatus in motion simultaneously at all stations in response to an impulse transmitted from one station, and comprising mechanical tripping means 16 on a svnchronous distributer so that the exact time of release of the apparatus is controlled by the synchronous distributer. A manually operated switch 20 is closed to determine the approximate time of starting of the auxiliary apparatus, which comprises cams 6, 8 for connecting a transmitter T and receiver R alternately to a line 1. To determine the exact time of starting, the switch, on the first subsequent closure of contacts 18 by a member 15 actuated by a cam 16 on a distributer shaft 3, actuates through a relay 23 a relay 25 which places a tripping bar 26 in position to be engaged by the member 15 on the next revolution of the distributer shaft 3.
