STEERING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 253,226, dated February 7, 1882.

Application filed September 10, 1881. (No model.)

'erence being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in steering apparatus; and it consists in compounding the leverage of the tiller, whereby it exerts an increased power in manipulating a series of rudders in the steering of watercraft, as will hereinafter more fully and at large appear.

To enable others skilled in the at t with which my invention is most nearly connected to make and usevit, I will proceed to describe its con struction and operation.

In the accompanying drawings, which form part of my specification, Figure 1 is a perspective view of the hull of a vessel provided with my improvement in steering apparatus. Fig. 2 is a vertical section of the same at line 111 of Fi 3. Fig. 3 is an end elevation of the same.

The ordinary method ot'conneeting the tiller to the rudder-stock is to form a mortise in the latter and secure the former permanently therein by means of keys or otherwise. This method of connecting the tiller involves the necessity of applying great force to the tiller for the purpose of manipulating the rudder, and often requires the pilot to throw the rudder into the desired position prior to any back movement of the vessel, otherwise it would .be almost impossible to manipulate it when backing the vessel.

My invention has for its object the manipulation of the rudder with casein either a backing or forward movement of the vessel. To accomplish this desirable result I extend the tiller beyond the pintle of the rudder, and pivoting it to an arm extending aft of the rudder-stock, with the tiller vibrating upon acenter forward of said rudder-stock, and when two or more rudders are employed coupling them together by means of coupling-links pivoted to arms extending aft of said rudderstocks.

Reference being had to the accompanying drawings, (t represents the aft portion of the hull of a vessel; (1, the skegs, to which the rudder-stocks c are pivoted, by means of pintlesfand stirrups, in the usual manner.

To the rudder-stocks 0 of the rudders t and t" are secured armsj, which are aft of and at right angle to said stocks, and are coupled together by means of links l, pivoted to said arms, as indicated at 70. The rudders t" are known to the art as kntickle-rudders, and the rudder i as the balanee-rudder.

To the upper end of the stock 0 of the rudder 1', and at right angle to said stock, andex tending aft of it, is an arm, h, to which is pivoted at g the extension b of the tiller b, which vibrates upon a center, 0, projecting vertically from a cap, at, secured to the middle skeg d.

From the foregoing description the skillful boat-builder will readily understand the construction of myimprovement and the relation that the several parts bear to each other. I will therefore proceed to describe the operation.

NVhen the tiller 1) is moved to the starboard the rudders i and t" will be moved to the larboard, and when the tiller 1) is moved to the larboard the rudders i and i will move to the starboard. The extension I), being pivoted at g to the arm It, will give to the tiller acompound leverage in lllitlllpllitlillllg the rudder t, and by coupling the rudders i. i to the rod der i, through the medium of the armsj and links I, pivoted as at It, a compound leverage of the tiller is applied to the three rudders shown in the present case.

Having thus described my improvement, what I claim as of my invention is- In a steering apparatus, the combination of the series of rudders and stocks 0 c 0, having fixed armsj projecting aft of said stocks. and links Z l for connecting said arms, and the tiller fnlcruined forward of one of the stocks, having an arm, h, projecting aft of it, and said tiller having an extension connected to said arm 71, substantially in the manneras and for the purpose herein shown and described.

JAMES REES.
