ABSTRACT:
A shaft lock for an automobile with a steering column. The steering column has a gear rim thereon with teeth on its periphery and a hollow cylinder is attached to the car body. A magnetic piston is slidably received in a hydraulic cylinder having a piston rod extending from the magnetic piston to the gear rim. An electromagnet is supported on the hydraulic cylinder and adjacent to the magnetic piston so that the field from the electromagnet holds the piston rod teeth out of engagement with the teeth on the gear rim when the ignition of the motor is turned on. The motor has an oil system connected to the hydraulic cylinder to force the magnetic piston away from the gear rim when the motor has started. A helical compression spring is supported on the hydraulic cylinder which urges the magnetic piston from the gear rim and disengages the teeth on the piston rod from the teeth on the gear rim. A coded switch is connected in series with a second switch connected to the electromagnet whereby a horn operates if the engine does not start after a predetermined number of tries.
