Improved Locking Balls for Logging Carriage.

摘要

A ball stop is locked to a cable by inserting the cable through an opening in the ball. The ball is then rigidly clamped in place by a wedge which is inserted into the aperture surrounding the cable and threads in the aperture and on the external part of the wedge mate and are screwed together to cam the wedge into frictional engagement with the cable.
