page_text: I, RICHARD FLEMING, of Boston, in the County of Suffolk State of Massachusetts,
one of the United States of America, Mechanic do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
My invention relates more especially to that class of rudders known as jury
rudders; and it consists in a novel construction and arrangement of parts as herein-
after set forth the object boing to produce a simpler and more effective device of this
character than is now in ordinary use.
The nature and operation of the improvement will be readily understood by all
conversant with such matters from the following explanation..
In the accompanying drawing
Figure 1 is an isometrical perspective view of my improved rudder detached from
the vessel.
Figure 2 a side elevation of the stern of a vessel with the rudder attached; and
Figure 3 a top plan view of the same.
Like letters of reference indicate corresponding parts in the different figures of the
drawing.
A represents the body of the rudder, B the rudder proper, and C the stern of the
vessel.
The body consists of a broad heavy piece of plank, one end of which is narrowed
and rounded to fit the rudder-port m and is provided with holes k, y, adapted to
receive the ropes or chains c, d by which it is secured to the vessel.
The rudder proper B is preferably composed of heavy plank, its upper end being
secured in a mortise in the outer end of the body A, so that when in use it is
suspended perpendicularly from said body, its free end being slightly bevelled on the
inner or forward side, as shewn at b.
Two holes f,fare provided in the rear or outer end of the body A for. receiving the
steering or tiller-ropes D.
In either side of the bulwark H are journalled, horizontally arranged pulleys, or
sheaves and upon the deck M between the pulley's g and the wheel K are journalled
horizontally arranged sheaves or pulleys h.
My improvement is designed for use when the rudder of a vessel has been lost or
accidentally unshipped or broken, and in its use the ropes or chains z are secured in
the hole of the body A and then passed through the rudder-port m and drawn taut

page_text: until the end of the body is firmly held against the stern of the vessel, when the
ropes are secured to cleats P on the deck M thereby flexibly connecting the
rudder and hull of the vessel and permitting the rudder to roll as it floats in
the water.
Stays or guards d, d are fastened at one end in the holes y, y of the body, their
other ends being secured to the bulkhead H of the vessel, their purpose being to hold
the rudder more firmly in position and prevent it from " slatting."
The tiller-ropes D are secured at one end in the holes f, and passed around
the sheaves g, g in the bulwark and thence around the pulleys h, h to the steering
wheel K.
This arrangement of parts permits the body of the rudder to float freely on the water,
the rudder proper B, being immersed thereby serving the purpose of the ordinary
rudder and enabling the helmsman to steer the vessel by means of the wheel K
in the usual manner.
I do not confine myself to the use of two ropes z for suspending the body A or
securing the same to the stern of the vessel, as one may be employed if preferred.
Neither do I confine myself to the use of the stays or guard ropes d as these may be
omitted if desired; nor to the use of the wheel K as any other suitable mechanism
may be employed for operating the tiller-ropes; nor to the use of the intermediate
sheaves for relieving any sudden strain or shock on the wheel, as these may be
omitted if preferred; chaius may also be used in place of the ropes.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed, I declare that what I claim is :-
First. In a rudder of the character described, the body A provided with the rudder
proper B, in combination with a rope or ropes z, for securing the inner end of said
body to the stern of the vessel, and filler-ropes D, substantially as described.
Second. In a rudder of the character described, the body A having the holes f, k, y,
and rudder proper B secured to said body, in combination with the tiller-ropes D,
pulleys, wheel K, stays d ropes and vessel C, substantially as, and for the
purpose, specified.
Third. In a rudder of the character described, the combination of the following
instrumentalities, to wit:a body provided with a downwardly projecting rudder
proper; a rope or ropes for securing the body to the vessel; tiller-ropes secured to
the outer end of said body, pulleys for said ropes journalled in the bulwarks of the
vessel, and a wheel for working said tiller-ropes, all constructed, combined and
arranged, to operate substantially as shewn and described.
Fourth. In a rudder of the character described, the body. A provided with a rudder
proper and with the stays or guards din combination with the rope z and tiller-
ropes D, substantially as described.
Fifth. In a rudder of the character described, the combination of the body A
provided with the rudder proper B; two tiller-ropes D; a rope or ropes for sus-
pending or securing the inner or pivotal end of said body to the stern of the vessel,
suitable sheaves for the tiller-ropes, and a wheel or means for operating the tiller-
ropes, substantially as set forth.
Sixth. In a rudder of the character described, the intermediate sheaves h, in
combination with the vessel C, wheel K, tiller ropes D and body A provided with the
rudder proper P, and rope z, substantially as, and for the purpose, set forth.
