ABSTRACT:
A tool for retrieving or placing test or process elements from and into a pressurized container has a relatively short run in/run out shaft that carries a connector for attachment to and rotation of a holder that mounts a test probe, test coupon, or the like, in the container. The run in/run out shaft is driven by a pair of concentric drive cylinders, rotation of the shaft being achieved by a longitudinally slotted rotation drive cylinder, and longitudinal motion of the shaft being achieved by rotation of a spirally slotted cam cylinder. The arrangement provides a shorter length tool and eliminates gears and close-fitting drive elements that are subject to wear and damage from trash that may be contained in the fluid of the system.
