ABSTRACT:
An apparatus or resilient link (24) provides relative movement of first and second members (36,38) for resiliency in limiting forces applied through the link (24). The link (24) connects, for example, a controlling member (14) such as a lever (14) or handle and a work mechanism (10) such as a valve (12) or shifting mechanism. In the resilient link (24), a first apparatus (44) moves the first member (36) from a first toward a second position (46,48) in response to exerting a first force (F.sub.1) on the first member (36) in the first direction (50) for resiliency to excessive force applied in tension on the link (24). A second apparatus (52) moves a second member (38) from a first toward a second position (54,56) in response to exerting a second force (F.sub.2) on the first member (36) in the second direction (58) for resiliency to excessive force applied in compression on the link (24 ).
