US Patent 7537428 Adjustably pivotable grapple with fixed heel

A grapple apparatus of a type having arms that pivot about parallel axes of a frame for grasping and releasing objects and wherein the entire grapple, including the grapple arms, pivots about a pivotal axis transverse to such parallel axes, and more particularly to a grapple which is pivotally adjustable about such pivotal axis between a first position and can be locked in at least the first and second positions thereof. A heel is fixed to the frame for supporting an object being grasped by the grapple when the grapple is in the first pivotal position thereof. A tooth is also optionally attached to the frame for permitting manipulation of the position of an object when the grapple itself is not being used.
