ABSTRACT:
The present invention relates to a lock which features projections located in a single plane of the rotor and stator lined into two opposing rows. The drillings for the main group of projections and their corresponding springs extend through the rotor to the opposite side of the frame or stator but not through it completely. This blind drilling forms the exact lodging for an antagonistic second set of projections and springs.
