ABSTRACT:
A package or carton lifter includes tongs which have two laterally spaced pairs of jaw levers physically connected intermediately of the first and second ends. A pair of cross-members rigidly connects the lever pairs at points below the lever-pivotal connections for pivotal movements in unison. First and second links pivotably connected to one another join the first ends of the levers of each pair for opening and closing the tongs, and a first handle extends between the connection points of the links. A second handle is substantially coextensive with the first handle and extends between the pivotal connections of the pairs of levers. Each of the cross-members has an inner side, and a gripping member is provided on the inner side of each of the cross-members for grasping a case or the like. A spring is wrapped around one of the pivotal connections and has first and second ends in contact with the jaw levers, respectively, of one of the lever pairs, urging the jaw levers to occupy a first position, where the second ends are closest to one another. The first and second handles may be jointly gripped and pulled towards one another for the jaw levers to occupy a second position, so that the second ends are furthest apart from one another. The gripping members are adapted to grip a case interposed between the jaw levers in the second position, when the first and second handles are released from the joint grip.
