ABSTRACT:
A linear stroke friction damped device adapted for resetting relatively moveable mechanism members by biasing spring action. Unidirectional resetting or multi-directional resetting are provided for. Displacement of the mechanism members attached to the device results in biasing spring loading and concurrent progressively increasing frictional damping as stroking movement of the device progresses toward end of stroke.
