Abstract
A throat formed between jaws of a rigid bifurcate gripper can be moved horizontally to receive an edge portion of sheet structure. The gripper is freely tiltable so that application of a lifting force to it will effect tilting of the gripper relative to the sheet structure to bind such structure between the jaws. Normally the gripper is positioned by a counterweight with its elongated throat horizontal. The lower jaw is of reflex angle shape and is positioned relative to the upper jaw so that downward tilting of the jaws will cause them to bind the sheet structure in the gripper throat.
