Abstract
A cable operating apparatus includes a pawl and ratchet arrangement for maintaining an operating lever in a cable-tensioning position. The pawl is bifurcated to define a pair of pawl tips, the pawl being pivotable in opposite directions for effecting alternate engagement of the pawl tips with the ratchet. The pawl contains a slot that receives the pawl pivot pin and which permits lateral movement of the pawl between a pair of end positions. An overcenter spring arrangement alternately pivotally biases the pawl in opposite directions when the pawl is displaced toward the end positions, respectively. A cam arrangement serves to effect lateral displacement and pivotal movement of the pawl when the operating lever is pivoted from the released position toward a cable tensioning position. When the operating lever is locked in a cable-tensioning position by the pawl and ratchet arrangement, further movement of the lever in the cable-tensioning direction causes release of the pawl from the ratchet, whereupon the operating lever may either be pivoted further in the cable-tensioning direction, or released for return to the cable-released or off position. According to a modification, a manually operable release rod may be provided for releasing the pawl from the ratchet.
