ABSTRACT:
An adjustable torsion-spring slipping clutch, especially useful for tape recorders, having first and second coaxial clutch sections which are rotatable about an axis of rotation. The second clutch section includes a sleeve which has a substantially circular cylindrical shape and is adjustable in diameter. A coaxially arranged cylindrical helical torsion spring is connected to one end to the first clutch section and its turns are wrapped around the sleeve, adjustment of sleeve diameter determining the torque to be transmitted between the clutch sections.
