Abstract
Novel ratchet loadbinder apparatus utilizing a spring-biased single pawl member carried within a slotted cam formed on the loadbinder's handle, the pawl member being selectively and reversibly positioned in one of two operating positions formed by bearing recesses at both ends of the slotted cam, such selective placement depending upon the desired direction of movement of an associated screw-threaded turnbuckle barrel. The loadbinder's handle carries a spring member utilized to maintain the pawl member in its preselected position during indexing handle movements. During working stroke handle movements, the pawl member is forcibly interposed between the selected bearing recess on the handle and an associated ratchet gear rigidly mounted on the threaded barrel.
