UNITED STATES .PATENT OFFICE.
HENRY LUMLEY, OF OHANOERY LANE, LONDON, ENGLAND.
IMPROVED RUDDER.
Specilication forming part of Letters Patent No. 38,172, dated April 14, 1363.
To all whom it may concerm.
Be it known that I, HENRY LUMLEY, of Chancery Lane, London, in the county of Middlesex, England, auctioneer, a subject of the Queen of Great Britain, have invented or discovered a new or Improved Rudder; and I, the said HENRY LUMLEY, do hereby declare the nature of the said invention, and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement thereof, reference being had to the accompanying drawings, and to the letters and figures marked thereon-that is to say:
The object of my invention is the construction of an improved rudder. For this purpose I construct a rudder in two movable portions, connected together edgewise, the outer or farther portion, which I call the tail,7 being at the outer end of the inner or hither portion, which I call the bodyJ The two portions are hinged, jointed, or articulated together, so that when the body is moved, turned, or worked to steer the ship or vessel, the tail also turns or works at the end of the body, and assumes various angles with respect thereto.
I guide or control the tail of my improved rudder by means of chains or ropes, or of chains or ropes combined with bars or rods, passing through slots or orices in the body portion ofthe rudder and attached at one end to a fixed point on the stern-post or hull of the vessel, and at the other end to a fixed point on the tail. The travel of the tail may be limited by ianges, stops, or abutments.
Having thus set forth the nature of my invention, I proceed more particularly to describe the best means known to mefor carrying the same into effect, with reference to the accompanying drawings.
Figures l and 2 are elevations showing opposite sides of a rudder constructed according to my invention. p
A B is my improved rudder. It consists of two portions, A and B, whereof A is the inner or hither portion, or portion nearer to the stern of the vessel, and B is the outer portion, or portion farther from the stern. The part A, I call the body 5 i the part B, I call the tail.
C is the stern-post, to which the portion A is connected by pintles and gudgeons a a., or any other means of hanging rudders t0 sternposts.
b b are pintles and gudgeons, or similar con-` trivances, which connect or hang the tail B to the body A, and allow the tail to turn or work at the end of the body when the latter is actuated.
D D2 are chains for controlling the action of the tail. Each chain is fastened at one end to a fixed point on the sternpost or hull of the vessel, and, after being carried through an oblique slot in the body A, is attached at its other end to the tail B near the outer edge thereof', at the opposite side of such tail to that at which it is fastened to the stern-post or hull. Thus, supposing the inner end of one chain attached to the starboard side of the sternpost or hull, the outer end would be connected to the port side of the tail, and vice versa. The two chains are fastened on opposite sides of the stern-post or hull, and therefore on opposite sides of the tail.
d', Fig. l, and d2, Fig. 2, are the xed points to which the ends of the chain D are attached.
d3, Fig. 2, and d, Fig. l, are the xed points to which the ends of the chain D2 are attached.
In Fig.3 four chains, D D2D3 D4, are shown. D3 is fastene'l in similar manner to D, and D'l in similar manner to D2, D D2 being fastened as explained in Figs. l and 2.
Instead of chains, ropes may be used, or bars or rods combined with chains or ropes.
e e2 are the slots or orifices in the body A, through which the chains pass. These orifices are obliquethat is to say, they are cut through the body A in a diagonal direction, or obliquely to the vertical planes of its sides, as shown in the horizontal sections taken through these orifices, Figs. 4 and 5. fices are protected with metal linings.
f f are grooved friction rollers or pulleys, which may be fitted in the slots e e2 for the chains to travel over.
g g are rubbing-plates to reduce the friction of the chains. They may be grooved, so that the chains may work in the grooves in them, or friction-pulleys maybe substituted for them.
When the rudder is of thin material, it may be desirable to have thick rubbingplates on the stern-post, to increase the power of the chains. If the form of the contiguous edges of the tail and body does not act as a sufficient stop to the tail, stops, abutments, or flanges may be fixed to the body for that purpose. The portion A is worked in the manner usual The orifor Working rudders, and when it turns or moves so as to take various angles to the foreand-aft line of the vessel, as usual with rudders, the part B Will turn or move at the end of the body A, taking various angles to the plane of the body A. The rudder, thus folding, presents a recessed surfaceV to the Water, as exemplified in the horizontal section, Fig. 6.
The improvedV rudder, constructed as directed, may be made to act as an ordinary rudder by taking off the chains or ropes and making the tail fast to the body, so that tail and' body may turn' or Work together 'as one rigid piece.
Having now described the nature of the said invention, and in what manner the same may be performed, I Wish it to be understood I do not restrict myself to any particular form of body A or tail B, as the same may be varied to suit the craft or vessel to Which the rudder may be applied.
And I hereby declare that I claim- The attachment of the tail B to the sternpost G by means of chains I) D2, or equivalent fastenings, Which pass obliquely through thebod y A, the several parts being constructed and operating substantially :in the manner and tor the purpose herein shown and described.
