Abstract

1,133,221. Preventing unauthorized use of I.C. engines. G. BURSLEM. June 16, 1966 [June 21, 1965; Feb.18, 1966], Nos.26085/65 and 7195/66. Heading F1B. [Also in Divisions E2, G4 and H1] In a door lock or ignition switch arrangement, a lock of the cylinder type incorporates an electric switch 1 and is provided with a key 4 having an extension 5. If extension 5 is the correct length it will depress a spring loaded plunger 6 and deflect a contact spring 8 carrying electrical contacts 9, 10 so that contact 9 touches a fixed contact 11 to complete the circuit from a battery 2 through switch 1 to ignition coil 3 when key 4 is turned. If the key is too short contact 9 will be in contact with contact 12 and turning of the key will sound a horn 13. In a modification, Figs. 2 and 3 (not shown) the key co-operates with a rod (17) to operate a switch (18) which has a contact (19) normally short-circuiting a horn push-button 20 so that if ignition switch (14) is closed the horn will sound but if the combined length of the key (15) and rod (17) is correct switch (18) will be operated to open contact (19) and close a contact (21) to permit normal operation.
