Abstract
Abstract A locking device for a vehicle having an internal combustion engine and a fuel injection pump is effective to lock an element of the vehicle necessary for its safe operation, such as the steering column, and to render the vehicle inoperative. Means are provided to preclude the possibility that the steering column or other element be locked while the pump is operative.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
185 words
An anti-theft device for a vehicle having an internal combustion engine and a fuel injection pump, said device comprising a lock, a bolt operable by said lock to be moved between locking and unlocking positions in which it locks and unlocks respectively, an element of the vehicle essential to the safe operation of that vehicle, an electrical switch operable by said lock and adapted for connection in a circuit starting said vehicle, drive means operable by said lock, drive transmitting means connected to said drive means and connectable to a fuel injection pump of a vehicle, to transmit pump opening and closing movement to said pump upon operation of said lock, said drive and drive transmitting means constituting means first causing said bolt to be moved to said unlocking position before said pump is opened as the lock is moved in a direction to cause pump opening movement of said transmission and, when said lock is moved in the direction to cause pump closing movement of said transmitting means, first causing said pump to be closed before said bolt is moved to said locking position.
Claim 2
Dependent Claim
185 words
An anti-theft device for a vehicle having an internal combustion engine and a fuel injection pump, said device comprising a lock, a bolt operable by said lock to be moved between locking and unlocking positions in which it locks and unlocks respectively, an element of the vehicle essential to the safe operation of that vehicle, an electrical switch operable by said lock and adapted for connection in a circuit starting said vehicle, drive means operable by said lock, drive transmitting means connected to said drive means and connectable to a fuel injection pump of a vehicle, to transmit pump opening and closing movement to said pump upon operation of said lock, said drive and drive transmitting means constituting means first causing said bolt to be moved to said unlocking position before said pump is opened as the lock is moved in a direction to cause pump opening movement of said transmission and, when said lock is moved in the direction to cause pump closing movement of said transmitting means, first causing said pump to be closed before said bolt is moved to said locking position.
Claim 3
Dependent Claim
60 words
A locking device as claimed in claim 1 including lost motion means between said lock and said drive transmitting means, said lost motion means being effective to delay activation of said drive transmitting means until said bolt is moved to said unlocking position as the lock is moved in a direction to cause opening movement of said drive transmitting means.
Claim 4
Dependent Claim
23 words
An anti-theft device as claimed in claim 1 wherein said drive means comprises a pinion rotatable by said lock and engaging a rack.
Claim 5
Dependent Claim
31 words
An anti-theft device as claimed in claim 3 wherein said lock is effective to cause rotation of a rotatable element having an eccentric, said eccentric being connected to rotate said pinion.
Claim 6
Dependent Claim
67 words
An anti-theft device as claimed in claim 4 wherein one of said eccentric element and said pinion comprises a pin and the other of said eccentric element and pinion comprises a slot within which said pin is disposed, relative movement of said eccentric element and said pinion producing lost motion as the lock is moved in the direction to cause opening movement of said drive transmitting means.
Claim 7
Dependent Claim
29 words
An anti-theft device as claimed in claim 1 wherein said drive transmitting means comprises a flexible element trained on a drum mounted for rotation upon movement of said lock.
Claim 8
Dependent Claim
18 words
An anti-theft device as claimed in claim 1 wherein said movement transmitting means comprises a fluid operated device.
Claim 9
Dependent Claim
34 words
An anti-theft device as claimed in claim 2 wherein said lost motion means comprises a pin and slot arrangement, relative movement of said pin and slot upon operation of said lock producing lost motion.
Claim 10
Dependent Claim
162 words
An anti-theft device for a vehicle having an internal combustion engine and a fuel injection pump, said device comprising a lock, a bolt operable by said lock to be moved between the locking and unlocking positions in which it locks and unlocks respectively an element of a vehicle essential to the safe operation of that vehicle, an electrical switch operable by said lock and adapted for connection to a circuit for starting said vehicle, drive means operable by said lock, drive transmitting means connected to said drive means and connectable to a fuel injection pump of said vehicle to transmit opening and closing movement to said pump upon operation of said lock, lost motion means between said lock and said drive transmitting means, said lost motion means constituting means delaying activation of said drive transmitting means until said bolt is moved to said unlocking position as the lock is moved in a direction to cause opening movement of said drive transmittinG means.
Claim 11
Dependent Claim
162 words
An anti-theft device for a vehicle having an internal combustion engine and a fuel injection pump, said device comprising a lock, a bolt operable by said lock to be moved between the locking and unlocking positions in which it locks and unlocks respectively an element of a vehicle essential to the safe operation of that vehicle, an electrical switch operable by said lock and adapted for connection to a circuit for starting said vehicle, drive means operable by said lock, drive transmitting means connected to said drive means and connectable to a fuel injection pump of said vehicle to transmit opening and closing movement to said pump upon operation of said lock, lost motion means between said lock and said drive transmitting means, said lost motion means constituting means delaying activation of said drive transmitting means until said bolt is moved to said unlocking position as the lock is moved in a direction to cause opening movement of said drive transmittinG means.
