ABSTRACT:
A hydraulic setting tool assembly for setting earth anchor and foundation devices comprising side-by-side hydraulic motive members. Each motive members comprises a piston movable within a cylinder. The piston has a piston arm extending out of the cylinder. Movement of a piston under the pressure of hydraulic fluid causes the associated piston arm to extend from or retract into its associated cylinder. A piston arm bearing plate is secured to the extended ends of the piston arms. A cylinder bearing plate is secured to the base of the cylinders. The bearing plates are parallel to each other and an opening is provided in each of the plates midway between the motors so that said openings are aligned for the passage of a threaded rod therethrough. An adjustable nut on the rod restrains one of the bearing plates against movement along the rod while the other bearing plate can move relative to the rod to force an earth anchor or foundation device into the earth.
