An electrical cable (20) is wrapped on and can be unwound from a reel (34) rotatable in unison with a brake drum (33) on a support (13,27). A clock spring (32) on the support (13,27) constantly urges the reel (34) to rewind the cable (20). A brake cord (36) fixed to the support (13,27) is wrapped in
An electrical cable (20) is wrapped on and can be unwound from a reel (34) rotatable in unison with a brake drum (33) on a support (13,27). A clock spring (32) on the support (13,27) constantly urges the reel (34) to rewind the cable (20). A brake cord (36) fixed to the support (13,27) is wrapped in the rewind direction around the drum (33) and connected via a train of chain links (A,B,C) to a spring (41) that tensions the cord (36) to act as a frictional one way clutch against the drum (33) to hinder rewinding in any selected unwound position of the cable (20). To release clutch action, a further train of chain links (C,D,E) is interposed between the spring (41) and a control connection (45), by pulling of which the tension of spring (41) can be relieved to allow rewinding. A still further train of chain links (A,F,G) is connected to the cord (36) and to a spring and buffer (53,55,21,60), adapted to re-tension the cord (36) momentarily for braking action in response to the cable (20) reaching fully rewound position defined by an abutment (61) on the cable (20) actuating the spring and buffer.

A reel assembly (22) comprising a support (13,27), a winding reel (34) rotatably mounted on said support (13,27), a brake drum (33) coaxially affixed to said reel (34), a flexible conductor cable (20) wrapped upon said reel (34) and extensible therefrom so as to rotate said drum and reel in a pay-ou
A reel assembly (22) comprising a support (13,27), a winding reel (34) rotatably mounted on said support (13,27), a brake drum (33) coaxially affixed to said reel (34), a flexible conductor cable (20) wrapped upon said reel (34) and extensible therefrom so as to rotate said drum and reel in a pay-out direction, a first biasing means (32) connected between said support (13,27) and said drum (33) and reel (34) for urging them to rotate in a rewind direction opposite said pay-out direction an elongated flexible brake element (36) fixedly connected at one end (37) thereof to said support (13,27) and wrapped on said drum (33), second biasing means (41) connected between said support (13,27) and the other end of said brake element (36) to tighten said brake element (36) frictionally around said drum (33) so as to arrest rotation of said drum and reel in said rewind direction while permitting them to rotate in said pay-out direction during which said drum tends to frictionally slide relative to said brake element (36), and means to relieve said second biasing means (41) so as to free rewinding rotation of said drum and reel in response to said first biasing means (32).
