摘要： A control device for a magnetic cylindrical lock having a cylindrical housing and a cylindrical plug disposed for rotational and axial movements in the housing, comprises a longitudinal bore in the plug, magnetic rotary members arranged for rotation across the longitudinal bore, and arresting means for blocking the rotation of the plug in one axial position of the latter and for permitting the rotary movement in another axial position.

摘要： The plug of a cylindrical lock includes at each side of its key channel a blind boring communicating with a conical recess in an arresting plate secured to the housing of the lock. The blind boring intersects cylindrical rotary control members arranged for rotation in the plug and each having a diametrical passage coinciding in one angular position thereof with the blind boring. A series of arresting balls is arranged in the blind boring and in respective passages in such a manner as to resume in the aligned position of the members a blocking position in which the terminal ball is in engagement with the conical recess. During the rotation of the plug by a correct key the arresting balls are shifted by the inclined surfaces of the conical recess into the blind boring and the plug is free to rotate. By the insertion of a wrong key at least one passage is misaligned and consequently the terminal arresting ball cannot be removed from its arresting recess.

摘要： A lock system has a master-only lock which can be opened only by a master key and a subordinate lock which can be opened by a subordinate key and a master key. The master-key slot of the master-only lock is formed with a plurality of parallel longitudinally extending and inwardly projecting guide ridges and a plurality of parallel longitudinally extending and inwardly open variable recesses interleaved with and parallel to the guide ridges. The master key is complementarily shaped. The subordinate lock has guide ridges and variable recesses identical to that of the master-only lock, and in addition is formed with further variable recesses in which fit corresponding further ridges on the subordinate key. Thus, the subordinate key is of larger cross-sectional area than the master key so that it cannot fit into the master lock. The various guide ridges provided in all the locks and variable recesses which change from lock to lock are interleaved with each other to discourage machining of a subordinate key down into a master key.

摘要： A lock has a cylinder formed with a keyhole and rotatable in a housing. At least one tumbler is displaceable into the keyhole into engagement with a bit of a key which can position the segments of the tumbler so as to allow rotation of the cylinder in the housing. In addition the key is provided with a magnet that can coact with a magnetic rotor to rotate this magnet into a position that aligns a notch on the magnet or a control wheel controlled thereby with a retaining element. The housing is formed at its back end with a recess in which one end of the retaining element is urged by a weak spring. Only when the notches on the rotors are aligned with tabs on the retaining element can this element be displaced out of the recess in the housing and allow rotation of the cylinder relative to the housing.
