ABSTRACT:
A motor driven rotary cam forces back a hammer against a spring and then suddenly releases it to provide an impact stroke to a pivoted massive lever which carries, at the end opposite the portion driven by a hammer, a lock pick needle held in a chuck. It is not necessary to feel out the position of the tumblers of the lock, because the impacts, repeated as necessary, drive the counter-pins away from the tumblers against their respective springs and an auxiliary tool carrying a weight, which does not need to be held in the hand of the operator, can turn the lock when the counter-pins have been propelled sufficiently far into the standing part of the lock. The force of the stroke, stroke length and repetition rate are all adjustable, as well as the torque applied by the auxiliary tool, in each case by a simple adjustment.
