ABSTRACT:
A portable tongs construction for the gripped handling of sheet materials that is comprised of a tubular handle internally containing a slidable plunger. Detachably supported at the common distal ends of both the handle and plunger are individual jaw units having opposed gripper faces arranged so as to enable lateral receipt of a sheet edge intervening therebetween. The plunger is spring biased relative to the handle to optionally effect either a normally open or normally closed operation of the jaw faces and is actuated via a finger button slightly raised from the surface of the handle. The jaw units are optionally replaceable so as to optimize suitability as is at least one of the gripper faces contained on one or other of the jaw units.
