Abstract
A dampener for cushioning engagement forces of an impacting mechanism. An impacting mechanism has relatively movable members that can be releasably coupled together. The coupling engagement produces forces which tend to deform the coupling members. An impacting mechanism, having an actuator with a releasable coupling member is coupled to a relatively movable impact plunger, contains a dampener which compresses or deforms to cushion the coupling force. An impacting mechanism having a dampener for cushioning the forces during coupling engagement prevents the coupling members from being deformed.
