Abstract: Force multiplication device comprising a low power reciprocable force output device serving to energize, near the end of low force stroke thereof, a coaxially aligned coupling mechanism serving to interconnect to rear shaft of said low force reciprocable force output device, a high power reciprocable force output device comprising a plurality of coaxially disposed, connected and cooperating air cylinders resulting in availability of multiplied force throughout remainder of stroke of low power reciprocable force output device.

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.
