A self-adjusting cable control device for automatically compensating for wear in a control cable system. The device includes a termination member connected at one end of a control cable and a connecting member attached to an actuation member. The connecting member carries a clutch for locking with the termination member upon application of force to the actuation member. Spring means are provided to move the cable with respect to the actuation member when the clutch is disengaged from the termination member. The clutch comprises a plurality of collet members which are movable radially and longitudinally and surround the termination member. The collet members have conical surfaces at one end adapted to engage complementary conical surfaces on the connecting member and serrations which engage complementary serrations on the collet members. The control device further includes a release tube that is accessible from the exterior of the device and can be engaged and moved axially inwardly by a clip to disengage the collet members and thereby permit easy connection of the device to the cables. In addition, provision is made for a separate clip normally holding the tube in a position and operable to release the release tube and the collet members to operative position.

A self-adjusting automatically compensating cable control device in a control cable system comprising a termination member adapted to be connected at one end of a control cable and having longitudinally spaced serrations on the exterior thereof, a connecting member adapted to be attached to an actuation member, a plurality of collet members having longitudinally spaced serrations thereon normally engaging the serrations on said termination member, spring means interposed between said termination member and said connecting member for moving the termination member longitudinally relative to the connecting member when the collet members are disposed from the termination member, said connecting member having a portion forming an internal conical surface and a portion having an external conical surface, said internal conical surface and said external conical surface on said connecting member being spaced longitudinally from one another in fixed relation on said connecting member, said collet members being positioned longitudinally between said internal conical surface and external conical surface on said connecting member, said collet members being movable radially outwardly to disengage the serrations on the collet members from the serrations on the termination member over the complete length of the serrations on the collet members, said collet members having external conical surfaces adapted to engage said internal conical surface on the connecting member for engaging the serrations on the collet members with the serrations on the termination member, the axial length of each said collet member between the external conical surface and internal surface thereon being less than the axial distance between said internal surface and said external surface on said connecting member, said collect members having internal conical surfaces adapted to engage said external conical surface on the connecting member for disengaging the serrations on the collect members from the serrations on the termination member, said collet members being movable longitudinally between a first position wherein the external surfaces of said collet members are in engagement with the internal surface of said connecting member and a second position wherein said internal surfaces of said collect members are in engagement with said external surface on said connecting member said collet members being in said first position wherein the internal surface of said connecting member and the external surfaces of said collet members are in engagement and with said serrations on said collet members in normal engagement with said serrations on said termination member when there is an external actuation force on said termination member and when the force on said termination member is reduced below a predetermined amount, said spring means acting on said termination member causes said termination member to move said collet members longitudinally to bring the collet members to said second position and cause said internal conical surfaces on said collet members to engage the external conical surface on said connecting member forcing the collet members to move radially outwardly and disengaging the serrations over the complete length of the serrations on said collet members from the serrations on the termination member allowing the spring means to move the termination member axially relative to the collet member and the connecting member until the force on the termination member is re-established to a predetermined amount.
