ABSTRACT OF THE DISCLOSURE A snap roller utilized as a snatch lock employs a pulley and a rod fabricated from a wire-like spring material to which the pulley is journalled. The rod has n portion of its length, located substantially in the central regions thereof to which the pulley is journalled. A pair of portions of the length of the wire-like rod extends radially outwardly from the longitud- inal axis of the pulley in a direction substantially parallel to one another. The ends of the wire-like rod are formed into oppositely directed hooks such that each of the distal ends approach, and if desired contact the opposed length of the pair of portions of the wire-like rod. In use, a rope or line may be passed between the hook-like ends so as to engage a groove in the pulley due to the fact that each hook-like end resides in planes that are skew to one another allowing the distal ends of the hooks to be forced outwardly from the opposed one of the pair of portions of the wire-like rod. In similar fashion an eye-hook or other bight-like element, such as an eye-hook or spring bight may be engaged within the opening defined by the hooks and the pair of portions of the length of the wire-like rod and the pulley, by passing the bight in between the hook- like ends until the portions of the bight pass the distal ends of the hook. A twisting motion to the bight or the wire-like -1- rod enables the bight to reside capturing the hooks. The line or the bight way be disengaged by reversing the pro- cedure utilized to capture these elements to the snatch block. An alternate embodiment utilizes a hook-like excursion on the hook-like ends of the wire-like rod which engage portions of the lengths of the wire-like rod in a locking like arrangement, which enhance the ability of the rod to carry great forces applied to the line or the eye hook carried thereby. -ii-
