Abstract
A mechanical lock of the type where a rod is normally locked for axial movement through a lock housing by a spring tightly wound about the rod and axially fixed to the housing, the rod being released by partially unwinding the spring. The lock is assembled without welding of the components to permit use of dissimilar materials in the lock housing selected for strength and weight characteristics and use of plated or painted components. The lock housing is configured to reduce the number of parts in the lock and adjustment can be made to eliminate axial free play of the locking spring following assembly of the lock housing.
