Abstract

9198. Preston, E. J. April 10. Signals, marine and ship.-Relates to means for transmitting engine-room and steering orders &c. in case of failure of the ordinary telegraphs. The apparatus is shown in duplicate form, as used for twin engine telegraphing. On the top of the ordinary telegraph transmitter three contact-pieces B, C, D are mounted, and these are connected to an ordinary electric bell and indicator in the engineroom &c. The order is transmitted by rotating the revoluble plunger A, until its pointer A<4> indicates the order to be transmitted, and then depressing it ; this operation completes the bell circuit between the proper contact B, C, or D and the contact-arm A<1> on the plunger. The plunger is prevented from shifting by the spring E engaging in a groove in the plunger. The resetting of the indicator in the engine-room &c. is caused to complete a circuit which gives a reply signal on the bell L. Instead of employing a bell and indicator, three bells of different tones, or a form of the telegraph described in Specification No. 18,661, A.D. 1893, may be employed.
