Claim 1
Independent Claim
188 words
A locking apparatus for a motorcar having an ignition switch, said apparatus comprising a cylinder lock with a keyway for insertion of a key, the lock including a rotatable operating portion coupled to the switch such that rotation of the operating portion will produce operation of the switch, a locking member having locking and released positions and coupled with said operating portion to be moved between said locking and released positions when the operatiNg portion is rotated, a displaceable engaging member operatively coupled with said cylinder lock to be moved between a first position in which the engaging member locks said locking member in the released position and a second position in which the locking member is released for movement to the locking position, and stop means for blocking movement of the engaging member to said second position when said key is inserted in the keyway, said stop means comprising a pivotal lever having an initial position partly projecting into said keyway, and a pivotal stop member acted on by said lever for movement into blocking position to prevent movement of the engaging member to said second position.
Claim 2
Dependent Claim
188 words
A locking apparatus for a motorcar having an ignition switch, said apparatus comprising a cylinder lock with a keyway for insertion of a key, the lock including a rotatable operating portion coupled to the switch such that rotation of the operating portion will produce operation of the switch, a locking member having locking and released positions and coupled with said operating portion to be moved between said locking and released positions when the operatiNg portion is rotated, a displaceable engaging member operatively coupled with said cylinder lock to be moved between a first position in which the engaging member locks said locking member in the released position and a second position in which the locking member is released for movement to the locking position, and stop means for blocking movement of the engaging member to said second position when said key is inserted in the keyway, said stop means comprising a pivotal lever having an initial position partly projecting into said keyway, and a pivotal stop member acted on by said lever for movement into blocking position to prevent movement of the engaging member to said second position.

Claim 4
Dependent Claim
46 words
A locking apparatus as claimed in claim 2 comprising a projection on said engaging member, said locking member having a recess in which said projection is received when the locking member has been displaced to released position and the engaging member is in said first position.
Claim 5
Dependent Claim
65 words
A locking apparatus as claimed in claim 3 comprising a second spring means, said second spring means acting on said engaging member and urging the same to its second position, and a second cam on said cylinder lock, said second cam being positioned to displace the engaging member to said first position against the action of the second spring means when the lock is turned.
