  • Patent number: 7566194
    Abstract: A ratcheting apparatus for engaging the winch driver of a winch used for tightening cargo straps, providing secure temporary engagement, with substantial leverage for turning the winch. The apparatus comprises a handle that removably inserts into the two sleeves of the apparatus. The teeth of the sleeves are arranged such that loosening motion allows the teeth of the respective sleeves to slip, one against the other, where winch tightening motion causes the teeth to engage and tighten a cargo strap. The spring of the rod of the apparatus provides correct tension between the two sleeves. A hardened leverage bar turns the apparatus. The apparatus is preferably made of metal or metal alloy, although more exotic polymers and matrixes may be used in construction.
