Abstract: An actuating device may comprise: at least one cylinder; means for providing fluid under pressure to the cylinder; a piston mounted in the cylinder for longitudinal sliding motion; a rod attached to the piston for longitudinal motion therewith; a crank member adapted for attachment to apparatus to be actuated; a mechanism connecting the rod and crank member adapted to convert longitudinal motion of the rod to rotary motion of the crank member; and a manual override assembly connected to the rod for displacement of the rod without providing fluid under pressure to the cylinder. The manual override assembly may comprise a ball screw mechanism in which the nut portion may be non-rotatingly attached by a hollow shaft to the end of the rod. The screw shaft of the ball screw mechanism may be mounted coaxially with the rod and rotatingly supported on a support housing adjacent to the cylinder. The end of the screw shaft may be adapted to receive a disengageable handwheel for rotation of the screw shaft and consequent reciprocation of the nut portion and attached rod.

Abstract: A device for translating rotary motion of one member into linear motion of another. It includes a rotating member, such as a screw, which is removably engageable with a threaded partial nut. On engagement, screw rotation causes linear nut movement. This movement may be used to control motion of further devices.
