ABSTRACT:
An improved combination lock mechanism including a dial adapted for removable securement thereto. Mechanically connecting a conventional wheel pack and drive cam combination to a lock cam is a locking lever pivotally secured at a point intermediate the opposite ends thereof to said lock cam, said lever having a first end adapted for engagement by said drive cam and wheel pack and a second end conforming to at least a portion of the peripheral geometry of said wheel pack. Finally, there is included a relock plate and means for biasing said relock plate against lock bolt connective members. Fence members are formed on said relock plate and spaced apart a distance slightly less than the distance between the ends of said connective members when said connective members are in an extended position. Thus, the urging of said relock plate against said extended members upraises said fence members to a position proximate the ends of said extended connective members whereby to inhibit the retraction of the locking bolts.
