Abstract
A cylinder lock is provided which comprises a cylindrical housing; a core which is rotatably mounted in the housing, thereby defining a shear line; a first tumbler slidably disposed in a first aperture; means for moving the first tumbler between a locked and an unlocked position; a second tumbler slidably disposed in a second aperture; and means for moving the second tumbler between a locked and an unlocked position. When the lock is in the locked position, the first tumbler extends across the shear line into the first aperture of the core. When a correct key is inserted into the keyway, the first tumbler is urged completely into the core below the shear line. The second tumbler is arranged such that when the lock is in the locked position, the second tumbler extends across the shear line and such that when the correct key is inserted, the second tumbler is urged completely into the housing above the shear line. The first and second tumblers re configurated such that the first and second tumblers resist radial movement if a tensioning movement is applied between the core and the housing.
