ABSTRACT:
A multiple bolt combination lock with a combination dial having a shaft rotatable with the dial and extending through a wheel post and a bottom pan to engage locking wheels having gates which can be aligned by manipulation of the wheel. The bottom pan is fixed to a top pan having a plurality of locking rods pivotably attached thereto at a distance from the center of rotation so that rotation of the pans in one direction causes the rods to retract and rotation in the opposite direction causes the rods to advance. When the gates are aligned, a lever arm mounted on the bottom pan pivots under the urging of a spring into a position latching the dial and pans together for rotation. When the dial is rotated in a direction so as to advance the rods into a latching position, a cam on the wheel post which extends through a slot in the bottom pan engages the lever arm to pivot that arm out of the gates after the rods are in the latching position.
