ABSTRACT:
Air pressure actuated locking power clamp released from static loaded condition by air pressure no greater than locking pressure notwithstanding a differential smaller release pressure area due to piston rod of air cylinder. Highly pressurized needle bearings in straight track portions of the clamp which actuate links connected to a pivoted clamp arm are critical elements in providing unexpected low pressure release. Similar needle bearings in all loaded pivots of conventional toggle clamps provide 100% improvement in ratio of apply force to clamping force.
