Abstract
Abstract In an ignition switch for automotive engines, a leaf spring ratchet prevents rotating the switch to engage the starter motor while the engine is running. The leaf spring has one end attached to a rotor and the other end free. It has a recess in the radially outermost surface and a tooth between the free end and the recess. A stop means adjacent the spring prevents rotation of the rotor to the ''''start'''' position when it engages the tooth and permits rotation of the rotor to the ''''start'''' position when it engages the recess.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
In a switch, the apparatus comprising an angularly movable rotor, a leaf spring having one end engaged with the rotor and an opposing free end, and a housing for the rotor and leaf spring, said leaf spring having a recess intermediate its length and a tooth between its free end and the recess, a first stop means in said housing adapted to fit in said recess and with said tooth, said tooth, recess and stop means being arranged so that when the tooth and stop means engage, movement of the free end of the leaf spring toward the stop means is prevented and when the recess and stop means engage, movement of the free end toward the stop means is permitted and means for regulating the distance of rotor rotation.
Claim 2
Dependent Claim
130 words
In a switch, the apparatus comprising an angularly movable rotor, a leaf spring having one end engaged with the rotor and an opposing free end, and a housing for the rotor and leaf spring, said leaf spring having a recess intermediate its length and a tooth between its free end and the recess, a first stop means in said housing adapted to fit in said recess and with said tooth, said tooth, recess and stop means being arranged so that when the tooth and stop means engage, movement of the free end of the leaf spring toward the stop means is prevented and when the recess and stop means engage, movement of the free end toward the stop means is permitted and means for regulating the distance of rotor rotation.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1 having a second spring adapted to engage a second stop means when the first stop mans moves relative to said leaf spring between the tooth and the free end of the leaf spring.
Claim 4
Dependent Claim
20 words
The apparatus of claim 1 wherein the means for regulating the distance of rotor rotation comprises said first stop means.
Claim 5
Dependent Claim
20 words
The apparatus of claim 2 wherein the means for regulating the distance of rotor rotation comprises said first stop means.
Claim 6
Dependent Claim
186 words
In an ignition switch for automotive engines having maintaining ignition of an engine and deactivation of the engine, the apparatus comprising an angularly movable rotor, a leaf spring having one end engaged with the rotor and an opposing free end, and a housing for the rotor and leaf spring, said leaf spring having a recess intermediate its length and a tooth between its free end and the recess, a first stop means in said housing adapted to fit in said recess and with said tooth, said tooth, recess and stop means being arranged so that when the tooth and stop means engage, movement of the free end of the leaf spring toward the stop means is prevented and when the recess and stop means engage, movement of the free end toward the stop means is permitted, means for regulating the distance of rotor rotation, when the leaf spring is rotated so that the free end bypasses the stop means, said ignition being maintained when the tooth and stop means are engaged and deactivation of the engine is effected when said stop means and recess are engaged.
Claim 7
Dependent Claim
186 words
In an ignition switch for automotive engines having maintaining ignition of an engine and deactivation of the engine, the apparatus comprising an angularly movable rotor, a leaf spring having one end engaged with the rotor and an opposing free end, and a housing for the rotor and leaf spring, said leaf spring having a recess intermediate its length and a tooth between its free end and the recess, a first stop means in said housing adapted to fit in said recess and with said tooth, said tooth, recess and stop means being arranged so that when the tooth and stop means engage, movement of the free end of the leaf spring toward the stop means is prevented and when the recess and stop means engage, movement of the free end toward the stop means is permitted, means for regulating the distance of rotor rotation, when the leaf spring is rotated so that the free end bypasses the stop means, said ignition being maintained when the tooth and stop means are engaged and deactivation of the engine is effected when said stop means and recess are engaged.
Claim 8
Dependent Claim
38 words
The apparatus of claim 5 having a second spring adapted to engage a second stop means when the first stop means moves relative to said leaf spring between the tooth and the free end of the leaf spring.
Claim 9
Dependent Claim
20 words
The apparatus of claim 5 wherein the means for regulating the distance of rotor rotation comprises said first stop means.
Claim 10
Dependent Claim
20 words
The apparatus of claim 6 wherein the means for regulating the distance of rotor rotation comprises said first stop means.
