Yale 101-1/2 comb lock

Note the 101 has a smaller depth of tooth engagement than the standard wheel. These two pictures show the engaged and disengaged positions of the wheel which occur in changing the comb. Not much movement is required to disengage the two wheel sections.

A second function performed by the keylock is to move the catch lever into the double notches in the outer wheels. This holds the outer wheels stationary as the inner wheels are repositioned during the comb change.
