ABSTRACT:
Position indicating device for constantly visually indicating angular disposition of the rudder of a marine vessel. The device employs a first ball screw cylinder which converts the linear motion from a second ball screw cylinder into rotary motion, which rotary motion is transmitted by a rotatable flexible shaft to the needle pointer of the device. Linear motion of the second ball screw cylinder is generated when the vessel's steering wheel is turned which rotates another flexible shaft connected to the second ball screw cylinder. Linear motion of the second ball screw cylinder controls the position of the rudder simultaneously with conversion of said linear motion into rotary motion by the first ball screw cylinder.
