Abstract
The tangs of the clutch and brake springs of a wrap spring clutch/brake unit are connected to separate sleeves which form the control collar of the unit. The sleeves are normally coupled for rotation in unison by an internally splined ring which may be slid to a released position permitting relative rotation of the sleeves for purposes of adjusting the torsional differential of the springs.
