Abstract
In liquid carrying cargo tanks of barges, with valves located inside the tanks at the bottom, valve position indicator assemblies are mounted at the valve operating shaft, above deck and fixed in position relative to the tank above the top of the tank. Each assembly includes a two-piece gear that is clamped onto the valve operating shaft. A mating gear is mounted on a shaft parallel to the valve operating shaft and having a screw thread on it. A nut mounted on the screw thread has an indicator pointer mounted to it and which moves vertically relative to the screw as the shaft is rotated and advances between a lowermost position on an indicator scale indicating valve closed condition, and an uppermost position on an indicator scale indicating valve open condition, as the valve operated shaft is rotated to operate the valve between the closed position and the open position. Various mounting arrangements are used.
