ABSTRACT:
Simple and inexpensive steering mechanism for marine craft wherein motion from a manually-operated steering wheel controls a remotely disposed rudder or other steering member. The present invention is characterized by an absence of gear mechanisms after the steering wheel for "stepping-up" the number of revolutions from the steering wheel in order that the steering member may be moved into steering position without requiring an excessive number of steering wheel revolutions. In lieu of such gear mechanism, a pulley-belt device is employed. As in the prior art, the stepped-up revolutions are conventionally fed into a rotatable flexible shaft assembly; and a ball screw cylinder or the like converts the rotary motion of the stepped-up revolutions into linear motion of a member which controls the steering. Since the steering wheel controls the direction of rotation of each pulley used in the system, as well as the direction of rotation of the rotatable flexible shaft assembly and the screw in the ball screw cylinder, all of which rotate in the same direction, it becomes readily known whether a ball screw cylinder contains a right or left hand threaded screw member therein, thus facilitating aftermarket replacement of steering systems. With prior art gear mechanisms, this capability is not readily available.
