ABSTRACT:
A cable control system including an adjustment device comprising a housing, a conduit fitting member mounted for reciprocating movement within the housing and adapted to be connected to the conduit of a cable system through which a cable strand extends. A spring yieldingly urges the housing in one direction. A ratchet gear is rotatably mounted in the housing and supports a pinion gear which engages teeth on the conduit fitting member. The ratchet gear has teeth with a pitch diameter greater than the pitch diameter of the teeth on the pinion gear and the teeth on the pinion gear are larger than the teeth on the ratchet wheel so that there are a greater number of teeth on the ratchet wheel than on the pinion. A removable ratchet detent engages the teeth on the ratchet wheel. In one form, the device automatically adjusts to change the tension on the cable conduit. In another form, the device is unlocked to provide an adjustment.
