ABSTRACT:
A controlled-torque apparatus having a first cylindrical member and a second cylindrical member held together by means of a ball bearing positioned in a hole in the sidewall of the second cylindrical member cooperating with a bearing race on the interior sidewall of the first cylindrical member, thus longitudinally securing while allowing relative rotation. The torque control is provided by a spring which exerts vertical pressure on ball bearings extending through apertures in the base of the second cylindrical member into part-spherical recesses in the base of the first cylindrical member.
