Abstract
Cable operating apparatus includes an automatic cable slack removing arrangement, characterized in that the cable tension-adjusting pawl is mounted both for pivotal movement between engaged and disengaged positions relative to the tension-adjusting ratchet, and for lateral movement between nested and extended positions relative to a pocket defined within the operating handle to which the pawl is connected. A cable-tension pawl spring biases the pawl toward the engaged and extended positions, so that when the pawl is engaged with the cable-tension ratchet, the cable tension will bias the ratchet in a direction to displace the pawl to its nested position in frictional engagement with the bottom wall of the pocket, whereby the pawl is more positively maintained in the ratchet-engaged condition. The pawl includes a lateral tab that engages a ramp on the main ratchet when the handle is in the cable-released position, thereby to disengage the cable-tension pawl from its ratchet and thus activate the automatic cable slack removing device.
