Abstract
The actuator has a housing with a longitudinal passage between a first end and an opening at a second end. A spindle, supported and moveable in the passage, has oppositely handed, first and second threaded portions each nearer a respective end of the housing. A first nut fixed relative to the housing is engaged with the first threaded portion. The spindle is rotated and moved relative to the first nut by a handle at the housing first end. A second nut fixed against rotation relative to the housing and engaged with the second threaded portion moves relative to and in the same direction as the spindle as the spindle rotates. The second nut is connectable through the opening to a device, and the spindle is rotatable by the handle for adjusting the device by movement of the spindle and the second nut.
