Abstract

121,144. Lyons, W. J., and Selective Signal Co. Sept. 14, 1917. Harmonic and reed telegraphs; tuned relays.- A n harmonic telegraph receiver or relay consists of a tuning-fork a or a reed or stretched wire possessing great inertia actuated by a magnet b and a motion-restraining device comprising a piece of rubber tubing c mounted on a spring f capable of lateral and longitudinal adjustment. The fork a may operate as an aural receiver or as a means for closing a circuit including a signalling or recording device. Specifications 117,090 and 117,247 are referred to.
