  • Lock plug assembly and a tumbler with a bent-over end therefor
    Patent number: 5970762
    Abstract: A reciprocating combinating tumbler for a lock plug assembly which includes a flat body portion and a bent-over (or enlarged) end portion is provided for use with a lock plug barrel having a generally cylindrical outer periphery, a longitudinal axis, a keyway slot formed substantially along the longitudinal axis, and a plurality of spaced-apart cavities formed substantially perpendicular to the keyway slot. In use, the tumbler reciprocates between an extended position wherein the bent-over end portion is spaced radially outwardly of the outer periphery of the lock plug barrel and protrudes into a longitudinal spline formed in the aperture of a housing, and a retracted position wherein the bent-over end portion is spaced radially inwardly of the outer periphery of the barrel and does not protrudes into the longitudinal spline.
