ABSTRACT:
An automatic self-adjusting cable control device comprising an outer member, an inner member having longitudinally spaced serrations, a spring yieldingly urging the inner member in one direction relative to the outer member, a clutch mechanism between the outer member and the inner member operable to adjust the position of the inner member depending upon the forces applied to the inner and outer members, respectively, and a mechanism for locking the inner member relative to the outer member comprising a first member fixed on the outer member and having an opening through which the inner member extends, a second member rotatably mounted on the first member about an axis spaced radially from the axis of the first member and having an opening through which the inner member extends. The opening through the second member is positioned so that in one rotatable position of the second member relative to the first member, the opening of the second member is aligned with the opening in the first member. In another position of the second member, the opening is out of alignment with the opening in the first member. The second member has an array of serrations on a portion of the opening therethrough. When the second member is rotated to one position, the array of serrations on the second member is out of engagement with the serrations on the inner member, and when the second member is rotated to a second position, the array of serrations is in engagement with the serrations of the inner member.
