Abstract

422,490. Two-part couplings. SHERLOCK, H. B., Carysfort, Glenageary, Dublin. July 14, 1933, No. 19988. [Class 38 (i)] A device for preventing the unauthorized starting of motor vehicles &c. comprises a casing a containing a pair of contacts e, f that are bridged to close a circuit by the insertion of a key v. One contact f is situated behind the keyhole and has a hole o into which the end of the stem w of the key fits. On turning the key the ward u enters a groove p in the other contact being frictionally gripped between a flat spring s and the side q of the groove p. The key thus bridges the gap g between the contacts e, f and closes the circuit through the cables j.
