Abstract
Abstract An overcenter-type load binder, having improved self-locking safety characteristics, defined by an operating lever having a clevis configuration at one end, a pivoted yoke mounted at such end, and a movable shank mounted inwardly of such end. Generally L-shaped slots are formed in the clevis arms of the lever and the shank is provided with projecting pins which extend through and beyond the confines of the slots for engagement in self-locking recesses provided in the yoke. Interengagement of the pins and recesses during movement of the lever toward a load unbinding position prevents ''''flying'''' of the lever during such unbinding.

Total Claims: 25
Claim 1
Independent Claim
117 words
In an overcenter load binder comprising an operating lever, a yoke pivotally connected with said lever adjacent one end thereof, and a shank movably connected with said lever inwardly of said end, the improvement comprising A. a generally L-shaped slot formed in said lever inwardly of said one end, B. a pin on said shank projecting therefrom and received in said slot in said lever, 1. said pin extending through said slot and projecting laterally beyond the confines thereof, and C. a recess in said yoke in which said pin is receivable when said operating lever is in a load-binding position, wheReby engagement of said pin in said recess releasably maintains said lever in said load-binding position.
