Title: SELF-CENTERING POSITIVE LOCKING GRAPNEL

Abstract

A grapnel used for remotely securing a load to be hoisted is described. The grapnel of the invention is generally conical in shape with a plurality of semi-open bores laterally disposed about the device. The bores meet at the apex of the grapnel and there provde a securing pocket for a spherical member. A load provided with a rigid support rod having a spherical member at its end can be secured by directing the spherical member down one of the bores and into the securing pocket. The major advantsges of the invention reside in the self- centering and positive locking features.
