Repeat lock and inhibitor for starters of combustion engines

Repeat lock and inhibitor for ignition devices, for preventing repeated operation of a starter in a combustion engine, comprising:

• having a substantially cylindrica interior space, there being a center accordingly;
• a flat disk having a circular periphery and being disposed in said space and coaxially thereto for rotation on the center, the disk being rotated upon insertion of an ignition key in an ignition lock and upon turning thereof, said disk having its circular periphery spaced from the cylindrical interior wall of said case;
• said disk being provided with a chord like channel, bounding said center on one side;
• a slide lock, slidably held in the channel, having curved end pieces being complementary to the circular periphery of the disk, and being longer than said channel but shorter than the internal diameter of said cylindrical space;
• the slide lock having two juxtaposed grooves with a common apex line as border, the apex or crest line running transversely to the direction of movement and length extensions of the slide lock;
• a spring biased lock element in the disk and having an edge for entering the groove to thereby hold the slide lock in a first and second end position respectively, the end positions differing as to which of respectively first and seconds ends of the slide lock extends beyond the periphery of the disk;
• a first, radially inwardly extending extension of the case defining a first stop for engaging the first projecting end of the slide lock when in the first end position;
• a second and a third stop defined by radial inward extension of the case and being separated by a shoulder having dimension such that upon radial abutment with the second end of the slide lock the latter is prevented from assuming the second end position,
• the second stop positioned at an end of the shoulder for engagement with the second end of the slide lock and in ignition position of the disk, preventing further turning of the disk;
• the third stop being at another end of the shoulder such that the slide lock when in the second end position abuts the third stop upon attempting repeat ignition and turning of the disk and key towards ignition position;
• the bias of the blade shifting the slide lock into the second end position, when upon opposite rotation of the disk the second end of the slide lock clears the shoulder;
• first cam means for engaging the first end of the slide lock and shifting same as the disk is turned out of a resting position toward ignition but said shifting being not farther than permitted by the shoulder;
• and
• second cam means effective on turning of the disk in opposite direction and engaging the second end of the slide lock into the first end position, further rotation then being prevented upon abutment of the slide lock element with its first end against said first stop.
