Abstract
A capstan winch for pulling cable through conduit includes means for measuring the torque applied to the capstan and a take-up reel. The torque measuring means comprises an inner drum connected by a tension spring to a concentric outer drum. A patterned disc on the inner drum is visible through a window in the outer drum. The pattern indicates the relative position of the inner and outer drums, which is correlated to the applied torque.
