Abstract
Abstract A cable storage device having an operating pulley which is driven by a spring for retraction of cable which is payed out from the device is provided with a friction clutch interconnecting the spring and the pulley so that the clutch slips when the spring has been fully tensioned by paying out of the cable thereby to permit further paying out of cable without further tensioning of the spring.

Total Claims: 31
Claim 1
Independent Claim
215 words
A cable winding device for a cable fixed at both ends, comprising housing means including a storage space for the cable, respective entrance and exit openings for the cable, an operating pulley, at least one pressure roller cooperating with the operating pulley to urge the cable against the operating pulley with sufficient force to assure positive drive of the operating pulley by withdrawal of the cable from the housing, a drive spring cooperating with the operating pulley so as to be increasingly tensioned as the cable is withdrawn from the device, frictional clutch means operatively interconnecting the spring and the operating pulley with such frictional engagement that the clutch means slips when the spring is substantially fully tensioned by withdrawal of the cable from the device thereby maintaining the spring in said substantially fully tensioned state and permitting further withdrawal of the cable while the spring remains in the substantially fully tensioned state, and a locking device adjacent the exit opening for holding a segment of the cable, the locking device comprising a chamber having a toothed surface, a toothed clamping wheel resting freely on the toothed surface and means defining a cable guiding surface spaced sufficiently from the toothed clamping wheel to form with the toothed clamping wheel a restricted passage for the cable.
