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.

Dampener for impacting mechanism

An impacting mechanism for impacting a surface. An impacting mechanism having plungers spaced apart and adjacent allows fractured pieces to fly away and has a latch assembly that puts side loads on the plungers. An impacting mechanism having an impact plunger disposed in generally centered relation within a tubular actuator shields the impact to contain fractured pieces and provides a plurality of latch assemblies to equalize loading. The impacting mechanism breaks composite material into a plurality of pieces.

Impacting mechanism

A lip seal assembly provides an axially adjustable seal between a rotating shaft, such as a crankshaft, and a stationary housing, such as an engine block. The assembly includes a generally ring shaped retainer circumscribing the shaft and having a hollow, cylindrical cavity therein which receives a slidably positioned lip seal mounting member. A plurality of ring shaped spacer gaskets enable the lip seal to be axially adjusted within the cavity such that the point of engagement of the lip seal with a running surface of the shaft may be changed.
