' Letters Patent No, 98,241, dated December 28, 1869.

.The Schedule referred to in these Letters Patent and making part o! the same.

To all .whom fit may concern y Be it known ythat I, EDWARD Fox, of the city and State of New York, have invented a new and usef-'ul Improvement in Steering-Apparatus; and I do -hereby declare the ibllowing to be a correct description of the same.

Before my invention,- a steering-apparatushasv been made containing two conical barrels, -from which chains .pass in opposite directions to the rudder vor tiller. In this charactervof apparatus, diiculty arises in keeping the chain or rope from becoming slack on lone side or the other, and allowing the rudder to move, if struck by a wave. h

The object of my'invention is to move't-he tiller or rudder by the 'action of vdifferential barrels, to which the ends of the chains are attached, so that the motion in either direction results from winding the chains from a smaller to a larger barrel, and the reverse.

The speed of movement depends upon the relative sizes of" the barrels, and the movement is uniform, aud slack chain is prevented.

In the drawing- Figure 1 isa plan View of 'my apparatus, and

Figure 2 is an elevation ofthe barrels, endwise, the shaft being in section.

The shaft a is supported in` suitable bearings, b b, and provided with the hand-wheel c.

Said shaft a'also carries the barrels d, e, f, and g. These barrels-are. made of suitable material, and the barrels e and f are of greater diameter vthan the barrels d and g.

The chain h hasit's ends'att-ached to the barrels d e, and the chain t has its ends attached to the barrels blocks Zon, at the eudsof the tiller-ropes or chains g. The chains h and t' pass respectively through the no, passing through the blocks s tto the tiller fr or rudder-head, iu :my convenient manner. i

. The chains It andi pass on' in opposite directions from the points of attachment to the respective barrels, so that when the shaft a is revolved in one direc tion, the loop of chain i passing through the block 'onv be correspondingly shortened, by being wound upon the larger barrel f as it islunwound from the smaller barrel.

During these movements the chains reeve throughI the respectiveblocks, and thev blocks themselves are moved, drawing the rudder to one side or the other.

In this apparatus the parts can be easily propoli tioned to the duty to be performed, for, when the barrelsare nearly of the same size, the movement: of the rudder will be slow and correspondingly powerful, and, if the barrels vary considerably in size,the'1n0tion will be more rapid, and the helmsman have less leverage over the rudder.

What I claim, and desire .to secure by Letters'latent, is Y The barrels'll, e, fand g', of two dii'erent sizes, to which the chains h and t are coi1uected,`in combination with the blocks l, fm,r s, and t, that are connected to the rudder, the parts being arranged and operating .substantially as set forth.

' In witness whereof, I have hereunto set my signature, this 7 th day of October, A. D. 1869.
