This video demonstrates the delay action of arming the Marsh v.2 time lock. Normally when all the movements in a time lock are wound to the desired time, the lock will go 'on guard' preventing the operator from dialing in the combination, In this lock, it will not go on guard until the operator turns a separate arbor to arm the lock. This allows the operator to wind up the movements to the desired time, but still allow the safe to be accessed as if the lock were off guard. This could be useful if one doesn't know when the safe is to be closed permanently for the day. To see the full details about this lock go to: my-time-machines.net/diebold_chicago_marsh.htm
