Abstract: Deck access box connected to a deck of a ship and to reach rods to operate valves below decks. The deck access box is fixed to the ship's deck. The deck access box includes a spindle connected to the reach rod by a suitable coupling. The top end of the spindle includes a recess used to turn the spindle which in turn operates the valve. The spindle has indicator apparatus coupled to it to show the travel position of the valve. The indicator apparatus includes indicators and a new and improved transmission for regulating the movement of the indicators to provide a uniform, non-intermittent, and continuous position indicator of the valve open-close status. The indicators are adjustable, rotate and travel a circular distance proportionally equal to the travel of the gate or other closing device of the valve, such as a door, gate, plug valve or other device.
