Boat's engine speed and direction of rotation of the engine's propeller shaft are remotely controlled at the helm. Movement of hand control knobs through a semicircular area controls the full range of speed of the engine as well as its forward-neutral-reverse actuator. The knobs rotate a pulley structure which steps up rotation to flexible shafts. The stepped-up rotation of the flexible shafts is converted to linear motion by ball screw cylinders having output members connected to the engine's speed and propeller shaft actuators.

A device for coupling power from a high speed rotating flexible shaft to a spindle of a portable worktool. The flexible shaft is contained within a casing. The casing is crimped within a ferrule which is threaded into a handpiece which an operator holds in one hand to guide the worktool. Upon movement of the worktool on the workpiece by the operator, the casing becomes twisted to encourage loosening of the threaded connection between the ferrule and handpiece, thus endangering the operator. In lieu of the prior art threaded connection between the ferrule and handpiece, a retaining member engages both to prevent their dangerous separation by virtue of the handpiece and retaining member being free to slowly rotate about the ferrule in a direction to automatically relieve twisting stresses introduced into the casing caused by movement of the worktool by said handpiece on or about a workpiece.

A handwheel rotates an improved flexible shaft assembly which causes a socket member to rotate therewith. The socket seats an adapter therein which is uniquely configured to engage tapered square valve stems of different sizes and degrees of taper. The flexible shaft assembly is provided with a ferrule at the handwheel end and another ferrule at the socket end. The casing of the flexible shaft is free-positioning by virtue of the ability of the casing to slowly rotate in the ferrule provided at either the handwheel end, or at both the handwheel end and socket end, thus automatically relieving casing torsional stresses.

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.

Steering mechanism utilizes a pair of serially connected pulley-belt systems having a stepped-up output which causes a flexible shaft to rotate in the remote steering of a marine vessel. Upon fracture of a belt and/or when travelling at high speeds, the safeguard mechanism permits a rapid changeover to a direct drive steering capability such that steering shaft rotation is transmitted directly to the output shaft which rotates the flexible shaft.

In a vehicle steering system for automobiles, for example, a steering column is provided with a rotatable flexible shaft at the end thereof for improving the ability of the column to absorb energy in a crash situation. The flexible shaft has at least one strip of a plastic material, preferably polyvinylidene fluoride film made piezoelectric by known methods, secured to an outermost winding of the flexible shaft. Turning the steering wheel will torsionally deflect the flexible shaft which causes the piezoelectric strips to generate millivoltages thereacross. A deteriorating flexible shaft will deflect more under torsional stress than a comparable newer flexible shaft and the piezoelectric strip or strips secured to the deteriorating shaft will consequently produce higher millivoltages. These millivoltages are amplified and fed to indicating means for indicating the degree of safeness of the flexible shaft.

A compact, gearless steering control unit for open fishing boats, for example, employs a pivoting stick or rod to control steering rather than a conventional steering wheel. The unit includes a plurality of pulleys and timing belts to rotate a flexible shaft which controls a steering member. The stick is centrally disposed enabling either front seat occupant to easily move it, or at either side of the boat. By eliminating the protruding steering wheel, the front seat fisherman have additional room to manipulate their gear. The steering control stick may readily be removed to deter theft of the vessel.
