IMPROVEMENTS IN RUDDERS.
My Invention relates principally to my patented rudder for which I obtained
Her Majesty's Letters Patent, No. 1150, dated 19th April, 1862, and No. 3013,
dated 1st December, 1863, and it has for its object to provide improved controlling
or guiding mechanism for the same, as hereinafter described, and to arrange the
same, in such a manner, that it is brought on the deck of the vessel, instead of its
being beneath the "counter" of the same, or in the water, as heretofore, whereby,
I am enabled to place such mechanism under supervision, and thus obviate the
necessity of descent, for the purpose of repairing, adjusting or arranging the same,
as occasion may require.
Now, for the purpose of my Invention, and according to one arrangement, I
provide the tail post, or uppermost part of the "tail" portion of my rudder, with
a bar, arm, or lever acting as a supplementary tiller, and I arrange the same in such
a manner that it works in and out of a guide, eye, or slotted piece which slotted
piece is free to turn or pivot around its axes, according to the movement imparted
to the said bar, arm, or lever, by the "body" portion of the rudder; the aforesaid
guide, eye, or slotted piece being held in a bearing, or support fixed to the deck of
the vessel. Thus, as the body portion is moved, in the ordinary way, the bar, arm,
or lever acting as a supplementary tiller, will work in and out of the eye, or slotted
piece, and will guide or control the motion of the "tail," and thus produce the
recessing movement of the rudder, as is well known.
In another arrangement, or modification, the bar, arm, or lever, acting as a
supplementary tiller may be slotted, and a pin, rod, stud, or other suitable con-
trivance may be arranged on the bearing or support, and may travel in the said

page_text: slot, and thus cause the tail portion to perform its movements in relation to the
body portion, as above stated, on the body being actuated by the tiller or wheel.
In a still further arrangement, or modification, I provide the tail post on deck
with a short bar, or lever, to which is jointed a connecting bar crossing over the
top of the body portion of the rudder, and jointed to a fixed post or point on the
same side, thus bringing about the recessing of the rudder.
I prefer that the form of the rudder, as a whole, shall be, as regards the body or
front part, of nearly rectangular shape, or slightly sloping upwards, with the "tail"
or after part attached thereto or hinged or jointed thereon. The two pieces, thus
connected, pass through a port, in the counter of the vessel, to any deck above the
water,

IMPROVEMENTS IN RUDDERS.
My invention relates principally to my rudder, for which I obtained Her Majesty's
Letters Patent, No. 1150, dated 19 April 1862 and No. 3013 dated 1 December
1863, whereby a recessed, instead of a plane surface of rudder, is presented to the
water, and my present invention has for its object to arrange the controlling or
O guiding mechanisin, in such manner, that it is brought on the deck of the vessel,
instead of being beneath the "counter" of the same, or in the water, as heretofore.
I am thus enabled to place such mechanism under supervision, and to obviate the
necessity of descent, for the purpose of repairing, adjusting, or arranging the same,
as occasion may require; my present invention has further for its object to provide
a stronger rudder than heretofore, and one less liable to fracture in the part where
the common rudder is weakest.
I now proceed with reference to the accompanying drawings to fully describe my
invention.
For the purposes of my invention, and according to one arrangement thereof, as
O shewn partly in vertical section, figure 1, and in plan figure 2, the rudder posts are
carried up through the counter of the vessel, and the second rudder post, or
"Lumley" rudder-post, is carried up behind the main or ordinary rudder post to
the deck.
.
The post of this second, or "tail rudder," A, thus carried up, I provide with a
5 bar, arm, or lever a. This bar, arm, or lever acts as a supplementary tiller, and is
arranged to work in and out of a guide, eye, or slotted piece b, which is free to
turn or pivot around its axis, according to the movement imparted to the bar, arm
or lever, by the main or body portion A*, of the rudder. This guide, eye, or
slotted piece b, is held in a bearing or support Z, which is securely fixed to the deck
of the vessel. Thus, as the body portion is moved, in the usual way, by the tiller
or wheel, the bar, arm, or lever a, acting as a supplementary tiller, and working in
and out of the eye or slotted piece b, will guide or control the motion of the "tail,"
and thus produce the angulation or recessing movement of the rudder, as is well
known.
In another arrangement, or modification, shewn partly in vertical section, figure 3,
end view fig 4, and plan figure 5, the bar, arm, or lever a, acting as the supple-
mentary tiller, is provided with a pin or rod c, which is arranged to work in a
slot g, formed in the bearing Z, whereby the tail portion A, is caused to perform its
movements, in relation to the "body" portion A*, as above stated, on the body
being actuated by the tiller or wheel, in the usual manner. Or the tiller may be
slotted, and travel over a pin or rod in the standard.
In a still further modification, or arrangement, shewn in side elevation figure 7,
and in diagram plan figure 8, I provide the "tail" post A, which, as before stated,
is now brought on to the deck, with a short bar or lever d, to which is jointed a
connecting bar e, crossing over the top of the body portion of the rudder, and jointed
to a fixed post or point f, on the opposite side to the bar or lever d, thereby
bringing about the angulation or recessing of the rudder, because, when the body
of the rudder is put to port, (for example) then the connecting bar pushes the "tail"
rudder to port, at an increased angle, according to the position of the fixed post f,
lever d, and the connecting bar e, and vice versa.
I prefer that the form of the rudder shall be, as regards the body or front part
thereof, of nearly rectangular shape, as shewn, or slightly sloping upwards, with

page_text: "
the tail or afterpart attached thereto, or hinged or jointed thereon. The two pieces
thus connected, pass through a port in the counter of the vessel, to any deck above
the water line. This port may be trunked in the usual way, as shewn at x, x.
The water, or wash of the sea, is prevented entering the vessel, or trunkway,
through the enlarged rudder port, by means of sliding plates, which plates also act
as a stop for the rudder. These sliding plates take the place of the usual stuffing
box, and also form a support for the rudder, and are shewn in section in figs 1 and
2, and in plan in figure 6; they are constructed as follows:-
i, is the upper plate, and h, is the lower one, which latter is bolted to the main
deck. These plates are somewhat of heart-shape, as shewn in plan in figure 6, and
the lower one thereof forms a framing, in which the upper plate i, is free to slide,
or partially rotate, according to the angulatory motions of the rudder. These plates
are channelled or grooved at j, j, and oil, or other lubricator, may be introduced
therein. The recessed portions of the lower heart-shaped plate, serve as stops, to
limit the movements of the rudder.
Another part of my invention consists in the construction of the strong rudder,
and rudder heads, as shewn in the drawings, wherein the body of the rudder is
carried up to the deck with almost the same area of surface throughout, thereby
admitting of a strong framing, and a stronger rudder generally, and where in the
common rudder the effects of torsion or straining, or a blow from the sea, would
have a bad effect, the extra strength in this arrangement would prevent any such
ill results.
Having now described the nature of my said Invention, and in what manner
the same may be carried into effect, I declare that I claim.
First. The arrangement of the second rudder post (or Lumley Rudder post)
carried up behind the main, or ordinary rudder post, and up through the deck, said
rudder post being provided with a bar, arm, or lever, acting as a supplementary.
tiller, and working in a pivotted eye, or guide, arranged on a bearing or support
on the deck, as herein described, and as shewn in figs 1 and 2 of the drawings, for
the purposes set forth.
Second. The arrangement of the second rudder post, carried up behind the
main or ordinary rudder post, and up through the deck, said rudder post being
provided with a bar, arm or lever acting as a supplementary tiller, and furnished
with a pin or rod travelling in a slot in the bearing, or support, on the deck,
as shewn in figs 3, 4 and 5; or with a slot working over a pin or stud in
the bearing or support, substantially as herein described and for the purposes set
forth.
Third. The arrangement herein described, and shewn in fig 7, for working the
rudder, whereby the mechanism is also brought on and and worked from the deck.
Fourth. The arrangement and combination of sliding or partially rotating plates,
as herein described and shewn in the drawings, for supporting the rudder, and for
preventing water entering the vessel or trunkway, also at the same time acting as
a stop to the angulatory motions of the rudder.
Fifth. The strengthening of the Rudder, and Rudder head, by constructing them
in the manner herein described, and shewn.
In witness whereof I the said Henry Lumley have hereunto set my hand
and seal this Fourteenth day of July in the year 1882.
