ABSTRACT:
A tumbler wheel scrambler assembly for combination locks of the type having a plurality of tumbler wheels and a driving cam arranged in a stack in a lock case with lost motion couplings for rotating the tumbler wheels upon rotation of the driving cam by a dial, and having a slidable bolt and pivoted fence lever for moving the bolt from projected locking position to unlocking position when the proper opening combination has been dialed. The lock case has a scrambler mounting post therein and the scrambler included a two piece housing of mating housing halves collectively defining guide channels for elongated slide members having hook formations protruding into positions to engage with gates of the tumbler wheels for spring forced scrambling of the tumbler wheel positions during displacement of the bolt from projected locking position. The scrambler housing halves have mounting ear formations for collectively encircling the mounting post to pivotally support the scrambler housing from the lock case.
