Abstract

See full text

A combination lock is provided wherein force is maintained by convex blocks of a thimble member to displace a setting push ring and allow setting of a new combination. The convex blocks of the thimble are engaged with arcuate edges of a push ring by rotation of the thimble. Subsequent to setting of a new combination, the thimble is rotated back to its original position.
