IMPROVEMENTS IN APPARATUS FOR MANEUVRING SHIPS AND VESSELS."
Year: 1862

page_text: LETTERS PATENT to Charles Lungley, of Deptford, in the County of
Kent, Shipbuilder, for the Invention of "IMPROVEMENTS IN APPARATUS
FOR MANEUVRING SHIPS AND VESSELS."
PROVISIONAL SPECIFICATION left by the said Charles Lungley at the
Office of the Commissioners of Patents, with his Petition, on the 8th
May 1862.
I, CHARLES LUNGLEY, of Deptford, in the County of Kent, Shipbuilder,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
APPARATUS FOR MANEUVRING SHIPS AND VESSELS," to be as follows:-
My apparatus consists of a blade or other instrument, or of two or more such
blades or instruments, caused to reciprocate or move with a to-and-fro or cscil-
lating motion, by means of a steam engine or other motive power, and to change
its or their inclination at each reciprocation, in order that the full manoeuvring
effect may be exerted upon the vessel to turn her in either direction, as may
be desired. The apparatus may be fitted either on the sides or under the
quarters or at the bow, but I prefer to place it at the stern near the propeller
in screw propelled vessels. The steam engine of the vessel may be used to
work my apparatus, or an auxiliary engine may be applied.
My apparatus may be used either as a simple rudder, or as two or more
rudders, or for forcibly manoeuvring a vessel and changing her direction.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I CHARLES
LUNGLEY, of Deptford, in the County of Kent, Shipbuilder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing. date the Eighth day of May in the year of our Lord One
thousand eight hundred and sixty-two, in the twenty-fifth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said
Charles Lungley, Her special licence that I, the said Charles Lungley, my
executors, administrators, and assigns, or such others as I, the said Charles
Langley, my executors, administrators, and assigns, should at any time agree.
with, and no others, from time to time and at all times thereafter during the
term therein expressed, should and lawfully might make, use, exercise, and.
vend, within the United Kingdom of Great Britain and Ireland, the Channel
Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN APPARATUS
IOR MANŒUVRING SHIPS AND VESSELS," upon the condition (amongst others) that
1. the said Charles Lungley, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals, should particu-
larly describe and ascertain the nature of the said Invention, and in what manner
the same was to be performed, and cause the same to be filed in the Great
Seal Patent Office within six calendar months next and immediately after the
date of the said Letters Patent.
•
NOW KNOW YE; that I, the said Charles Lungley, do hereby declare the
nature of my 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 Drawings hereunto annexed, that is to
say-
My apparatus consists of a blade or other instrument or of two or more
such blades or instruments caused to reciprocate or move with a tu-and-fro or
oscillating motion, by means of a steam engine or other motive power, and to
change its or their inclination at each reciprocation, in order that the full
manoeuvring effect may be exerted upon the vessel to turn her in any direction
desired. The apparatus may be fitted either on the sides or under the quarters
or at the bow, but I prefer to place it at the stern near the propeller in serew-
propelled vessels. The steam engine of the vessel may be used to work my
apparatus, or an auxiliary engine may be applied.
My apparatus may be used either as a simple rudder or as, two or more

page_text: rudders, instead of the ordinary rudder,, or for forcibly manoeuvring a vessel
and changing her direction.
Figure 1 of the accompanying Drawings is a side elevation, and Figure 2 is
an end view of so much of an apparatus for manoeuvring ships and vessels as
will be necessary to illustrate the manner in which I prefer to carry my
Invention into effect.
a is a turntable, upon which the whole apparatus is fitted and with which it
may be made to revolve; b'is an aperture in the turntable and in that part of.
the skin and side of the ship where the apparatus is fitted, through which the
shaft c of the manoeuvring blade or propeller c¹ passes. The aperture is
conical to allow room for the play of the shaft. Where the apparatus is
placed above the water line this aperture requires no packing, but where it is
below, and which is usually the case, packing must be used. The shaft c
passes through a ball and terminates in a head e. The ball works in a
bearing, not shewn, and is free to move to and fro and to oscillate as it has
motion communicated to it, as hereafter described. f, f, is a quadrant frame..
supported by brackets f', f', between which frame the heade of the shaft.c
travels; g., are pins or studs on the head e, and united by universal joints to
connecting rods h, h', linked to a frame i, , which is pivoted on a pink,
passing through the shaft c and ball. The frame i receives an alternate tr=
and-fro motion through links 1, 1, united at one end to the frame i at m, and at
the other to the cross heads n, n, of the piston rods o, o, working in the cylin-
ders o, o'; p is a fly wheel with two cranks q, q, united by connecting rods 1,7,
to the frame i, for regulating the motion thereof. The cranks are arranged in
such manner that one crank has the lead of the other, to enable the blade to
alter its position at the end of each stroke, in proportion to the power of the
machinery and the extent of play imparted to the frame i.
When a single
engine only is used for imparting motion to the frame i, then the quadrant f,f,
carries a guide r, a detached view of which is given at Figure 3; this guide is
formed with double grooves s, s¹, in which a stud t, fixed to the head e of the
blade travels. By this means, when the stud t reaches the end of its course
in, for example, the top grooves, it falls or slides into the bottom groove, and
so cants or feathers the propelling blade at each end of its course. Thus, it
will be seen that the blade is caused to act on the water in a similar manner to
that of a scale worked at the stern of a boat.
The direction in which the vessel is manoeuvred or propelled is regulated by
the position of the turntable. Thus, when the axis of the turntable is in a
vertical position, the vessel may be moved in any desired direction. If the
axis is horizontal, similar to that of the shaft of a screw propeller, the vessel

page_text: may be manœuvred but not propelled. If the axis is placed at a slight angle
with the horizontal line, the vessel can be manoeuvred and propelled forward
but cannot be made to move astern. Sometimes I dispense with the engine
described, and impart motion to the quadrant frame direct from the main
engine of the ship.
In some cases I dispense with the turntable. The apparatus given at
Figure 1 is shewn fitted to the lower deck of a ship with the propelling blade
passing through the dead wood, and although this is the position I prefer, yet
the apparatus may be fitted above the water line and in any part where
(whether it be bow, stern, or midships of the ship) found most convenient.
And having now described the nature of my said Invention, and in what
manner the same is to be performed, I declare that I claim as my "Improve-
ments in Apparatus for Manoeuvring Ships and Vessels," the employment of a
blade or blades made to move to and fro, to oscillate, and feather by means
of apparatus or machinery constructed and acting substantially in manner and
for the purposes herein-before described and illustrated in the accompanying
Drawings.
In witness whereof, I, the said Charles Lungley, have hereunto set my
hand and scal, this Eighth day of November One thousand eight
hundred and sixty-two.
