Abstract
Abstract A safety locking mechanism for automobiles wherein the key turning with the lock rotor controls the switch of the vehicle circuitry through a rod coaxially carried by the rotor. The latter releases the bolt of actual locking means for a predetermined angular setting of the key which releases a yielding stop and allows thereby a spring to urge the bolt into its locking position. Another spring urges the rotor back into its normal position for which the engine is operative as soon as the starter has been actuated for a further position of the key. Repeated actuation of the starter is also prevented by an auxiliary contrivance.

379 words
An antitheft arrangement controlling the ignition and starter circuits of an automobile comprising a lock including a rotor and a stator, a key slidingly engaging the rotor along a plane parallel with the axis of the latter and including an extension projecting beyond said rotor, said key being adapted to be angularly shifted between its normal position corresponding to a closing of the ignition circuit, a first locking terminal position and a second terminal position corresponding to the closing of the starter circuit, a driving member axially and angularly rigid with the lock rotor, tenons carried eccentrically by the driving member on the side facing away from the rotor, a rod coaxially rigid with the rotor, a rotary switch controlling the circuits and directly engaged by said rod to be controlled by said rod, a bolt adapted to slide transversely of the lock stator between an outer operative locking position and a retracted inoperative position and provided with a slot, parallel with the direction of its sliding motion and through which said rod freely passes for all positions of said bolt, said bolt having shaped sections cooperating successively and respectively with said tenons whereby the bolt is normally held in its inoperative position and released at the first terminal position of the key, elastic means urging the bolt into its locking position, a spring urged block pivotally carried by the bolt and adapted to be held against movement together with the bolt by the extension of the key for said first terminal angular position of the latter and to retract upon movement of the key away from said first terminal position the bolt being urged by its elastic means into its operative position upon removal of the key when in its first terminal position. 2. An arrangement as claimed in claim 1 comprising an annular spring inserted against torsion coaxially within the driving member and a stationary stop adapted to engage one end of said spring upon angular shifting of the key beyond its normal position towards its second terminal position to tension said spring and make it urge subsequently the driving member back into the position for which the key is in its normal position, said annular spring being independent of and actuated separately from said elastic means.
Claim 2
Dependent Claim
43 words
An arrangement as claimed in claim 1 wherein at least one of the tenons on the driving member holds the bolt in its collapsed inoperative position and releases it solely when the key has been brought into its first terminal position and removed.
Claim 3
Dependent Claim
37 words
An arrangement as claimed in claim 1 wherein the elastic means includes a coiled spring operating against torsion and the ends of which engage respectively a stationary point of the vehicle and a projection on the bolt.
Claim 4
Dependent Claim
43 words
An arrangement as claimed in claim 1 wherein the shaped sections on the bolt include two systems of projections provided with slopes and recesses which systems carried by the side of the bolt facing the driving member cooperate each with a corresponding tenon.
Claim 5
Dependent Claim
46 words
An arrangement as claimed in claim 1 wherein one of the tenons cooperates with a slope on the bolt to hold the latter fast against the action of the elastic means for all the positions of the key between its normal and its second terminal position.
Claim 6
Dependent Claim
174 words
An arrangement as claimed in claim 1 comprising a safety mechanism preventing repeated closing of the starter circuit, including a cam-shaped washer coaxially engaging the transverse surface of the driving member and provided with cut out sections forming passages for the tenons and for the extension of the key and adapted to be angularly shifted to a limited extent with reference to the driving member, the periphery of the driving member being provided with a ratchet-shaped notch, a spring-urged pusher member fitted in a stationary part of the vehicle radially of the driving member and washer and adapted to engage the notch in the driving member upon return of the key from its second terminal position into its normal position and consequent relative angular shifting of the washer with reference to the driving member and to be held in said notch until the key is shifted beyond its normal position in the direction of its first terminal position to release the driving member by an angular shifting of the washer in the opposite direction.
Claim 7
Dependent Claim
217 words
An arrangement as claimed in claim 1 comprising a safety mechanism preventing repeated closing of the starter circuit, including a cam-shaped member coaxially engaging the transverse surface of the driving member and provided with cut out sections forming passages for the tenons and for the extension of the key and adapted to be angularly shifted to a limited extent with reference to the driving member, the periphery of the driving member being provided with a ratchet-shaped notch, a spring-urged pusher member fitted in a stationary part of the vehicle radially of the driving member and washer and adapted to engage the notch in the driving member upon return of the key from its second terminal position into its normal position and consequent relative angular shifting of the washer with reference to the driving member and to be held in said notch until the key is shifted beyond its normal position in the direction of its first terminal position to release the driving member by an angular shifting of the washer in the opposite direction, the peripheral outline of the cam-shaped washer including two arcuate sections of different diameters and the periphery of the driving member being that of a cylinder the outer diameter of which is equal to that of the larger of said two different diameters.
