Screw-steer′ing gear.

A screw on the axis of the steeringwheel may be made to act upon the rudder-head through the intervention of nuts, or nuts and rods. M ‘Williams’s gear (English) operates by means of a right and a left hand screw d e on the axis a of the steering-wheel. f f are two traversingnuts, and h h two traversing-rods, parallel to the spindle, and fixed respectively to the two traversingnuts at i i, and each passing through a guide-eye in the other nut. k k are two links jointed respectively at j j, to eyes on the traversing-rods, and at l l to the two arms of the yoke. b is the rudder-head.

A modified form of screw-steering gear was introduced by Reed (English). It has a similar right and left screw operating nut-blocks, which slide on parallel guide-bars. Each nut-block has a pin which engages in a slotted lug on the cap of the [2074] rudder-head, and thus turns the rudder when the screw-axis is rotated. See steering.
