Title: Operating cable for spring-loaded location bolt - is guided by flared location sleeve for non-axial cable movement
IPC: F16C1/12
Filed: 1975-04-10
Abstract: The cable-operated location bolt (1) is held in its locking position by a compression spring (8). A coupling (2) is used to attach an operating cable (6) to the bolt. When tension is applied to the cable, the spring (8) is further compressed by pulling the bolt (1) along its location sleeve (9).
