Claim Text:
1. A hand operated hydraulic press pliers tool comprising an upper stationary handle having an upper jaw forming the front end of the upper stationary handle, a lower jaw having front and rear ends being pivotally fixed to the upper stationary handle disposed to oppose the upper jaw, a hydraulic cylinder assembly disposed longitudinally within the upper stationary handle and having a rear end being a cylindrically shaped tool cylinder having a bottom pivotally fixed to the upper stationary handle near the upper stationary handle rear end, and a front end being a yoke pivotally fixed to the lower jaw at a location offset between the lower jaw front end and the lower jaw rear end, the hydraulic cylinder assembly comprising a lower moving handle having a distal end, a proximate end pivotally fixed by a pivot pin to the yoke, and a pump lever disposed near the lower moving handle proximate end and arranged to contact the hydraulic pump assembly of the hydraulic cylinder assembly, and adapted to activate the tool by a user pressing the lower moving handle and the upper stationary handle together to roate the lower moving handle around the proximate end pivot pin moving the distal end towards the upper stationary handle thereby pressing the pump lever towards the hydraulic pump assembly, activating the hydraulic pump assembly, forcing hydraulic fluid into the tool cylinder of the hydraulic cylinder assembly, lengthening the hydraulic cylinder assembly and forcing the upper and lower jaws to close.
