Abstract: An improved J-hook (20) includes an eye portion (21) having a circular transverse cross-section; an arcuate hook portion (22) having a circular transverse cross-section; a shank portion (23) arranged between the eye and hook portions and having an oval-shaped transverse cross-section; a first transitional portion (24) between the eye and shank portions and having a transverse cross-section in smooth continuous transition from the circular transverse cross-section of the eye portion to the oval-shaped transverse cross-section of the shank portion; and a second transitional portion (25) between the shank and hook portions and having a transverse cross-section in smooth continuous transition from the oval-shaped transverse cross-section of the shank portion to the circular transverse cross-section of the hook portion. The improved J-hook is drop-forged of "MT-10" steel, and exhibits a markedly-improved strength-to-weight ratio.

Abstract: An over center load binder assembly is disclosed comprising a crank member, a clevis type draw bar with leg elements pivotally connected to a first portion of the crank member, a pull link pivotally connected to a second portion of the crank member and a lever handle, pivotally connected to the crank member and comprising a cam surface, radial to the axis of the lever handle pivotal connection, having a maximum lobe swell sufficient to displace the pull link from an alignment between the leg portions of the clevis type draw bar to release the assembly from tension.
