inited @States THOMAS ROBIN AND CHARLES E. BURK, VOI? SHEBOYGAN, WISCONSIN.
Letters Patent N a. 98,636, dated January 4, 1870'.
IMIPROVEMENT IN SHIPS RUDDERS.
The Schedule referred to in these Letters Patent and making part of the same To rwhom it may concern Be it known that we, THOMAS ROBIN and CHARLns E. BURR, of Sheboygan, in the county of Sheboygan, and State of VVisccnsin, have invented a new and useful Improvement in Ships Rudders; and we do declare that the following is a true and accurate dc.- scription thereof, reference being had to the accompanying drawings, and to the "letters of reference marked thereon, "and beinga part of this specification, in which- Figure l is an elevation of the ster'n of a ship, fitted with Vour improved rudder, the hull a-nd rudder being partially in section, to better show their construction and arrangement.
Figure 2 is a horizontal section, on the line a b, in fig. 1.
.Like lettersA refer to like parts in each figure.
'Ihe nature of this invention relates to an improvement in the construction and method of attaching and operating rudders for steering steam and sail-vessels, and consists inthe peculiar construction of the rudder, which is hinged to the stern-post by a bolt extending down through the deck, and i-n operating the Sallie by means ofa chaiusecnred to the rudder-post, which is otherwise independent of it, and is stepped in the shoe ofthe keel, in a space between the stern-post and the dead-wood of the stern of the hull, the whole operating in such a manner as will enable the ship to steer easily, and answer hei' helm smartly, when put hard over, as hereinafter more fully shown and set forth.
ln the drawings- A represents the stern of a vessels hull, and B the keel.
O is the stern-post, dat on its rear face, and has its lower end supported by an extension of the keel, forming the shoe d. y
D is a rudder-post, stepped on the shoe, a space being left between the stern-post and the dead-wood c, of the stern of the hull, for that purpose. The rudder-post extends up through the deck, and is rotated in the usual manner.
E is a sectional and partially-folding rudder, composed of four or more 'vertical leaves or sections of wood, e, e2, e, and e, hinged together by the pintles f, adjusted by proper nuts on their outer threaded ends,'as shown.
The front edges of thesections are chamfered each way ii'oui the centre, while the backV edges are left square.
The forward section, e4, of the rudder, is hinged to the stern-post by a rod, l, passing through its pintles, g1, and through similar pintles, g2, in the stern-post.
g The-rod F is passed down through an opening in the deck, as shown.
The pintles g1 and g2 are. adjusted and secured in position by proper nuts on their threaded ends, the
forward edge of the stern-post and rear edgeof the By means of this nut, the slack of the chain may be 4 taken up, when necessary.
l, l2, and l, are metallic rollers, revolving on staples secured to the sections el, e, and e4 of the rudder. Under these rollers the chain passes.
o are metallic wear-plates, secured to the stern and rudder-posts, to avoid damage by the friction of the chain on their surfaces.
The action of our rudder may be explained as follows:
The rudder being amidship, as shown in the drawings, by partially rotating the rudder-post D, in either direction, the opposite end of the chain, ex erting a strain on the section e, rotatesit on its pintle until its chamfered edge strikes the after edge of the section c, which rotates unt-il its 'chamfered edge strikes the rear edge ofthe section e, which rotates until it strikes the rear edge of the section e, which turns ou the pintlc-rod F, until its chanifered edge abuts against the rear edge of the Stern-post, by which time the helm and rudder are hard over, the rudder not standing at a iight angle to the keel, but describing an are of a circle in that direction; the water being held in the hollow part of the rudder, until the greatest resistance can be obtained from it against 'the last section of the rudder. It will be noticed that the last section of the rudder is turned first, enabling the vessel to answer quickly, when but a slight change in her course is required, as the last section is hard over before the second section moves.
What we claim as our invention, and desire to secure by Letters Patent, isi l. The joint-ed sectional rudder E, as described, hinged to the' stern-post, and operated by an independent rudder-post, substantially as herein specified.
2. The independent rudder-post D and chain G, in connection with the rollers l1, l2, and l, bolts j, nuts k, and plates i, arranged and operating substantially as described and for the purposes set forth.
3. The pintle-bolt IP, when extended up through the deck, for shipping and unshipping the rudder when necessary.
