Abstract
A submergible chamber is provided with flanges at the outward ends of chamber guide arms, wherein each flange engages a stanchion. In one embodiment the flanges are selectively electromagnetic with the stanchions, and with sufficient force, the flanges are held to the stanchions thereby positioning the chamber at a specific depth. In another embodiment, the flange is adapted to pivotally grip the stanchion, and further each stanchion is provided with a vertical gear rack engaging the driven gear of each respective work arm so as to accurately position the chamber at a specific depth whereat the clamp holds the chamber at that depth.
