ABSTRACT:
A resilient control link assembly for a control system for transmitting a mechanical signal from a transmitter to a receiver so as to prevent component damage resulting from force overload situations due to response differences of components, fluid pressure failure, etc. The assembly includes two link elements which cooperate with the receiver and transmitter and are hinged together at a main hinge for relative swinging thereabouts from a datum relationship. Two following members are hinged to the first link element for rotation about a follower hinge spaced from the main hinge and are adapted to contact the second link element. A resilient member interconnects the two following members to force the members to cooperate with the second link element to maintain the link element in the datum relationship. When the datum relationship is disturbed, the following members are moved apart and the resilient means opposes this movement tending to draw the link elements back into the datum relationship.
