ABSTRACT:
A deck box valve operator and position indicator assembly characterized by a sprocket (66) supported by the housing (18) on a plateau (70) adjacent the spindle means (46) and having a plurality of radial forked (74) arms (72) with arcuate peripheries (76) extending between adjacent arms to extend about the circular circumference (78) of the spindle means (46). The spindle means (46) has a concaved recess (80) interrupting its circular circumference in an annular groove extending above the spindle means (46) for receiving the arms (72) of the sprocket (66). A gear train interconnects the sprocket (46) and an indicator ring (62) rotatably disposed in the housing for establishing a ratio between the number of revolutions of the spindle means (46) and the ring indicator (62) means whereby the ring (62) indicates the position of a valve means (12) between open and shut. A co-axial pin (84) which is supported by the spindle means (46) radially outside of its circular circumference (78) and in the center of the concave recess (80), slides into the slot (74) of one of the arms (72) to rotate the arm through the concave recess (80) so that the next adjacent arcuate periphery (76) compliments the approaching the circular circumference (78) of the spindle means (46) as the pin (84) slides radially out of engagement with the arm.
