the first, second, and third collectors are axially aligned and in separate relationship to each other; means for forming a first cavity between the first and second collectors; means for forming a second cavity between the second and third collectors; an intensifier piston placed in the first cavity; a reservoir piston placed in the second cavity, the reservoir piston defines third and fourth chambers in the second cavity, and the reservoir piston has a central bore therein; a coupler intensifier rod coupled with the intensifier piston, the intensifier rod passes through at least one opening in the second manifold in the central bore of the reservoir piston; a drive cylinder placed in separate relationship from the master cylinder; means for forming a third cavity within the drive cylinder; a piston placed in the third cavity of the drive cylinder, the piston defines the fifth and sixth chambers on each side of the piston; a fourth chamber adjacent to the reservoir piston and the sixth chamber is adjacent to the piston each containing hydraulic fluid; a passage means for placing the fourth and sixth chambers in fluid communication with each other, the passage means has one end juxtaposed with respect to the master cylinder and an opposite end attached to the drive cylinder; a piston rod attached to the piston, the piston rod has a free end cantilevered from the cylinder; means for introducing pressurized fluid into the third chamber adjacent to the reservoir piston to cause the reservoir piston to force hydraulic fluid from the fourth chamber of the reservoir piston into the sixth chamber of the drive cylinder which is adjacent to the piston in such a manner that the piston and the fixed piston rod advance at a predetermined first rate towards the workpiece; and a means for introducing a pneumatic means pressurized into the first chamber adjacent the intensifier piston to cause the intensifier piston to move and further to move the coupled intensifier rod into at least one opening of the third manifold to act on the hydraulic fluid. it is stepped up for insertion into the sixth chamber of the drive cylinder to cause the piston rod attached to the piston to advance at a second predetermined rate toward the workpiece.
