IMPROVEMENT IN STEERING-APPARATUS.,

The Behedule referred to in these Letters Patent and making part of the same Y. I, EBENEzEI GREEN, ofEast Gloucester, in the county .of Essex, and State kof Massachusetts, have invented an improved Steering-Apparatus, of A\which the following is `a specification. Naturc'and Objects of the Intention.

The invention makes use of a .hand-wheel, actuating a shaft having gearing which operates the toothed segment of the rudder-head. wherebythe rudder is `operated and performs its work in any direction. desired.` Theifasteningsor couinings of the shaft are also so constructed that when thel rudder grounds in shoal water, or strikes any obstacle and is lifted up,

. the whole apparatus is lifted, and when the obstrucg tion is removed falls back without injury or displace` meut. of any of its parts ;v and the object of this invention is so to apply the wheel, shaft,pi nions, gearing; and other apparatus to the rudder-head, as to seem e greater safety to the rudder, and greater ease aud eiiciency f Description of the Accompanying Drawings.

of the segment of :Generali Description..

A represents that lpart of a vesselA to which the steering-apparatus is applied.`

-. bis the rudder-head to which is attached `the rudder-post descending through the deck tothewater, in the usual manner; the rudder-head also has a seg ment constructed and extending outward in the man; ner seen `in fig. 1 in the drawings, upon the extremity l1n the end of `res 1n drawing.)

f Theend of thebottom of the segment rests upon.

a roller, k, secured to the housing by a screw or other fastening, upon which it is movable; also another roller, 7tsecuredin like manner, plays in the groove j by turning the wheel, the rudder, it will be seen, is easily moved in either direction, and at the same time. it is perfectly secured. The boxes f f are let into' mortises in the top of thesupports L l, and are movable, so that, in case the rudder strikes an obstacle, or is thrown upward, it carries with it the shaft of the wheel, with the boxes, 85o.

The wheel is made inthe usual manner, and is at tached to the shaft'h, the shaft passing through the boxes f f in the manner seen in figs. 1 and2, and through the top of the cap e. Through the top of the boxes and cap are screws, which are brought down upon the shaft, or a fender upon the shaft. 'lheobject of these screws upon the shaft is to secure .the rudder in any position desired. Instead of these screws a dog may be used, striding the shaft upon the rail at the m end of the rudder-head segment outside the gearing,

and fitting into teeth, pins, or other fastenings upon the endy ofthe segment.

The whole apparatus, except the wheel, may be 'covered with a box or other covering having openings to the screws;A By means` of the wheel, the pinions on the shaft running in the gearing upon the segment of the rudder-head, great power may be ,brought to bear upon therudder. The movements of the rudder are also steady and uniform in operating, and if the rudder is thrown up no injury will result therefrom.

. Claims.

1. The arrangement of the movable boxes ff', and

Athe movable cap e, having adjusting-screws m m m.,

the wheel g,'aud the shaft h, having pinions fi, with the support-s l `I, and the rudder-head b, having gearing d, whereby the rudder may'be thrown upward without injury to the parts above named,.the whole being combinedl and operating'substantially vas and forv the p urpose described.

2. The arrangement of the groove `i, the rollers k k', in combination with the segment of the rudder-head, having gearing d, and operated by the' wheel y and shaft h, with its pinions t, the several. parts above named heilig constructed, combined, arranged, and operating substantially as and `for the purpose described Y EBENEZER G. GREEN.
