ABSTRACT:
A spring clamp for holding a paper log (rolled up newspapers) while twisting tie wires around the end portions thereof. The clamp comprises a pair of spring-actuated curved jaws which have a laterally flexible cord across the free ends of the jaws to embrace the log, the cord extending through jaw openings and being connected to the ends of springs projecting laterally from the jaws. The springs are arranged to buckle when the jaws are separated to provide a large range of opening movement of the jaws by a substantially constant jaw opening force and a substantially constant tension on the cord.
