Leiters Patent No.. 67,686, datct August 13, 1867.

IMPROVED STEERING APPARATUS.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, JOHN P. TEALn and WALTER J. BnAssrNGroN, of the city of Brooklyn, county of Kings, and State of' New York, have invented a new and improved Mode of Operating the Ruddei and Steering Apparatus of Steam andvother Boats; we do hereby declare that the following is a full' und exact description thereof, reference being had to the accompanying drawing, and to the letters of reference marked thereon.

The nature of this invention consists in the application of certain mechanical devices to the rudder or rudders of steam and other boats, so as to enable the pilot to connect and disconnect the rudder directly from the pilot-house instead of dependingr on the deck-hand as at present, thus giving the pilot full control of the boat at all times, and preventing mischief from evil-disposed persons pulling out the rudder-pin, s at present arranged. v

Figure 1 represents a side elevation of a ferry-boat with the invention attached, wherein A. representsthe hull of the boat; B M, the two kinds of rudders used; C, the lock or bolt in position securing' the rudder B;

D, centre-pin upon which bolt C moves; E, rubber spring impinging upon bolt C; F, main bolt or pin upon` which rudder B moves; G, recess in hull of boat to allow bolt C to rise;` H, chain attached to bolt C andleading to pilot-house I; J, quadrant to which is attached chain H; K, guide-rollers upon which chain H moves; L, ice-breaker; M, opposite rudder from B, N, yoke connected withrudder M; O, crown-piece in which yoke N is suspended; P, chain which operates yoke N, throwing it out of gear from the rudder M, and leading te pilothouse S; Q, chain which `operates yoke N, throwing it in gearonrudder M, and leading to pilot-house S; R, guide-rollers upon which chains P and Q move; S, opposite pilot-house; T, double quadrant to which are attached chains P and Q.

To enable others skilled in the art to make and use our invention, wewill proceed to describe its construe'- tion and operation.

We construct a rudder hin shape and form similar to B, iig. 1, with a recess represented by dotted line, iig. 4, ofA suicieut capacity to admit the movable bolt C, which turns upon the end pin D, fig. 1. At the upper end of bolt C, fig. 1, is connected the chain H at G, said chain H passing'along under the deck of the boat, directed by the guide-rollers K to the pilot-house I. A spring made of rubber is placed at E for the purpose of keeping the bolt C firmly in its place. A recess, G, is made in the hull of the boat A, iig. 1, to permit the bolt C to be raised when operated upon by the pilot at J, in the pilot-house I. The rudder B, iig. 1, is held in its place by the main bolt F running up through the hull A to the deck, and secured by a. nut and washer in the ordinary way, thus allowing the rudder B'tlo revolve on-its centre freely when relieved from the bolt C, by the pilot, by moving the quadrant in thedirection of the arrow at pilot-house I. We also place upon the rudder B, figs. 1, 4, and 5, a, sharp-edge projection, indicated by fred lines at L L, which operates as an ice-breaker relieving the rudder -from largemasses of ice when floating against the boat. A steam pipe, (in the direction of the arrow,

from the boiler is passed through the hull A to the recess G to free all the working parts from ice and prevent freezing.

Operation: The rudder B- is now locked; the baat starts from the ferry; the pilot raises the quadrant J in pilot-house I, g. 1, in the direction of the arrow; the chain H H moving in the required direction communicates its motion'to the outerend of the bolt C, at G, -and raises it out of the recess in rudder B, freeing it from bolt C and allowing it to turn readily on the main bolt F, thus being subject instantly to the will of the pilot. At the end of the trip the pilot releases the 'quadrant from its i'astenings, the chain H H drops by the action of the rubber spring E, the bolt C'falls in thelrecess-ot' the rudder B, holding the latter firmly in its position .ready for'the return trip, all without the aid of a second party, and subject te the will of the pilot alone.

In order lto make use of the p'resent'rudders in use we apply the following device: We construct a crownpiece, O, figs. 6, 7, 8, 13, and 14, ofz cast iron or' other inaterialfivith a recess of the necessary shape and size.

to admit the movable yoke N, figs. 9, 10, 11, and 12; said yoke N having a journal on each end, figs. 7 and 9, with a slot in thermiddle, X, suiicientlyrvide to `pass over the rudder M,as seen at N, iig. 14.- Thus constructed, these two pieces NO, iig. 7, are fitted so as to allow the yoke N to move freely on its bearings U U in and out, figs, 6 and 8. vThe crownpiece is now securely fastened under the stern of the boat at V, tig. 1, and properly' adjustedv so that the yoke N will fall directly over the upper edge of the rudder, figli. The guide-rollers R R R are 110W placed in their proper position,.g. 1, the chains P Q attached to the lower end of yoke N, figs. 1 and 6, running along' under the deck to pilot-house No. 2, where they are secured to the doublel quadrant T, and subject tothe samceoperatinand 'command of thc pilot asin the previous case in pilot-house No. 1.

Our invention is new, inasmuch as nothing has over been used before like it. -It is novel, onaccount of Aits simplicity of construction. It is-use'ful, on account of the facilities it offers to the pilot to haveV full and sole control of the rudder at all times, Without depending upon the deck-hands or other persons for assistance..

1. We claim theconstruction; application, and arrangement of the movable' bolt C, in connection with the rudder B, substantially yas'land-tbr the purpose set forth. I

2. The sharp-edge projection L,or ice-breaker on rudder B, substantially as and for the purpose set forth.

v 3. Also the yoke N, in connection .with the crown-piece O and rudder M, substantially as described and for the purpose set forth. i Y i JOHN P. TEALE,
