page_text: LETTERS PATENT to George Edward Casebourne, of West Hartlepool,
in the County of Durham, for the Invention of "IMPROVEMENTS IN
APPARATUS FOR STEERING VESSELS AND FOR SHIFTING MATERIAL THEREIN AND
THEREFROK.
"
Sealed the 11th July 1871, and dated the 17th January 1871.
PROVISIONAL SPECIFICATION left by the said George Edward Case-
bourne at the Office of the Commissioners of Patents, with his
Petition, on the 17th January 1871.
I, GEORGE EDWARD CASEBOURNE, of West Hartlepool, in the County
of Durham, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR STEERING VESSELS AND FOR SHIFTING MATERIAL
THEREIN AND THEREFROM,' to be as follows:-
"
These improvements have reference to vessels employing steam power,
and have for their object the utilization of steam power for the purposes
of steering vessels, thereby effecting a great saving of power and time,
also in combination therewith applying steam power for the purposes

page_text: of shifting material in and from the vessel, as for instance, raising
ashes from the hold.
The improvements consist in applying steam power (by means of
suitable gearing) to the apparatus for steering at present in use; and
further in employing the steam power to shift material.
The improvements may be carried into effect by transmitting the
power either from the donkey engine or from the main engine to the
steering apparatus at present in use by suitable bevilled wheels and
friction cones conveniently affixed thereto so that by means of turning
a handle from left to right or vice versa, either one set of bevilled wheels
or the other are by the action of the friction cone put in motion, thus
making the apparatus revolve either in one direction or the other, and
so putting the helm to port or starboard as required; a brake may be
furnished, by employing which the rudder may be kept at any desired
angle.
The steam power may be employed or not as desired and does not
interfere with the ordinary apparatus, further, as regards the employment
of the steam power for shifting material, the improvements may be carried
into effect by employing the same means that transmit the power to the
steering apparatus to transmit the power by means of bevilled wheels
and friction cones to suitable drums or wheels for the purpose of raising
ashes from the hold or moving material in or from the vessel.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Edward Casebourne in the Great Seal Patent
Office on the 17th July 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
EDWARD CASEBOURNE, of West Hartlepool, in the County of Durham,
send greeting.

Letters Patent, bearing date the Seventeenth day of January, in the year 3
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fourth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George Edward Casebourne, Her

page_text: special licence that I, the said George Edward Casebourne, my executors,
administrators, and assigns, or such others as I, the said George Edward
Casebourne, my executors, administrators, and assigns, should at any
time agree, with, and no others, from time to time and at all times there-
after 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 "Im-
PROVEMENTS IN APPARATUS FOR STEERING VESSELS AND FOR SHIFTING MATERIALS
THEREIN AND THEREFROM," upon the condition (amongst others) that I, the
said George Edward Casebourne, my executors or administrators, by an
instrument in writing under my, or their, or one of their hands and
seals, should particularly 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 George Edward Casebourne, 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 :-
The improvements have reference to vessels employing steam power
and have for their object the utilization of steam power for the purposes
of steering vessels, thereby effecting a great saving of power and time,
also in combination therewith applying steam power for the purposes of
shifting material in and from the vessel, as for instance, raising ashes
from the hold.
The improvements consist in applying steam power (by means of
suitable gearing) to the apparatus for steering at present in use, and
further in employing the steam power to shift material.
The improvements may be carried into effect by transmitting the
power either from the donkey engine, or from a steam winch, or from the
main engine, or from any convenient engine (with which the vessel may
be provided and having power available for the purposes of the Invention).
to the steering apparatus at present in use by suitable bevilled wheels
and friction cones conveniently affixed thereto, so that by means of
turning a handle from left to right, or vice versa, either one set of bevilled.
wheels or the other are by the action of the friction cone put in motion,.
thus making the apparatus revolve either in one direction or the other,

and so putting the helm to "port" or "starboard as required; a brake
may be furnished, by employing which the rudder may be kept at any
desired angle.
The steam power may be employed or not as desired, and does not
interfere with the ordinary apparatus.
The accompanying two Sheets of illustrative Drawings further illus-
trate the manner in which the Invention is to be and may be performed.
In both Sheets the lines drawn in black indicate the ordinary steering
apparatus at present in use, and the red lines indicate the additions in
accordance with the improvements.
Sheet No. 1 shews arrangements for application of steam power from
a donkey engine or any other convenient engine working in one direction,
that is to say, not admitting of the quickly reversing its direction, and
therefore requiring the intervention or interposition of reversing gear if
applied to steering purposes.
Figure 1 is a side elevation, Figure 2 a plan, and Figure 3 a back
elevation with some of the parts removed.
a is deck or platform of vessel; b, ordinary steering wheel; c, framing;
d, e, shafts; f, g, gearing; h, chain wheel, and i, tiller or rudder chains;
all as heretofore.
"
The following are new: A is driving pulley for hempen endless belt
(or a chain) in communication with engine, and passing over such
intermediate guide sheaves as circumstances may require. B, shaft
driven by same. C, bevil wheel driven by the last-mentioned shaft.
C*, C', bevil wheels which can be brought into gear with C, constructed
with clutch boxes and running loosely in contrary directions upon the
shaft D, which is a continuation of d and controls the ordinary steering
apparatus. E is a double friction cone or other clutch turning with
shaft D, but sliding thereon to engage either with C* or C³ as controlled
by the forked end of the hand lever F. G is an ordinary friction strap,
break wheel, and strap (new in the combination described) applied by
foot plate G to maintain the rudder at any required angle. H is
pulley; I, chain; and K, another pulley in communication with index
or pointer L. When the lever F is in a middle position, as shewn, the
steam engine is inactive on the steering apparatus, but by moving it to
the right or left it will control the position of the helm. The apparatus

page_text: as described admits of being controlled at the option of the helmsman
either by hand power from the wheel 6 or by steam power from the lever
F, with the assistance of the break G.
Sheet No. 2 shews arrangements for application of steam power from
a steam winch that can be reversed by link motion (such as in common
use on many vessels for loading, unloading, and various purposes) or
from a steam crane or any convenient engine employed on the vessel
for loading, unloading, working the ship, or otherwise that admits of
being quickly reversed, and therefore not requiring the intervention of
reversing gear if applied to steering purposes.
Figure 1 is a side elevation, Figure 2 a plan, and Figure 3 a front
elevation with some of the parts removed.
a, b, c, d, e, f, g, h, and i denote as before, and k, k, are guide pulleys
for i; is a pinion on e, and m, m, toothed sector and index pointer worked
from l. All the above parts are as heretofore.
The following are new: A is a chain (or a hemp or other belt may be
substituted) leading over fair leader pullies A* from the steam winch
or crane to the wheel B which revolves loosely upon the shaft d. C is a
single cone or other clutch turning with the shaft d, but sliding thereon
to gear by means of forked handle with the clutch with which the wheel'
B is constructed, and thereby to drive the said wheel when required. D
is a handle or lever on a spindle working in the post or column F. The
spindle has arms F* at the bottom, by which and by the cords or chains
E motion is communicated to the ordinary reversing lever or handle of
the steam winch. One of the chains pulls in one direction from the
handle, the other passes over a sheave and pulls in an opposite direction
so that by putting the handle D to "port" (on the adjacent dial plate)
the winch works in one direction, when it is in the centre as shewn the
steam is shut off, and by putting it to "starboard" the winch works in
the contrary direction. The spindle also carries at its foot a third arm Ġ
with short length of chain G* connecting it to the tiller or rudder chain i
so that when the handle is at "port" or starboard " the extremity of
the arm G will be at the spots P or S respectively, and when the chain i
is in either direction at the intended full extent of its action, it will by
the connecting chain G* pull back the arm G, and thus shut off the
steam at the winch. This is a self-acting arrangement to provide
against the helmsman's possible want of sufficient attention, and possible
"

The ordinary or old parts of the combined apparatus represented in
Sheet No. 2 admit by modification thereof the application of the double
conc or other cluth and bevil reversing gear hercin-before described
substantially in the same manner as represented in Sheet No. 1, in which
event a winch or engine with link reversing motion will not be required,
but an ordinary donkey or other convenient engine may be substituted.
Having now described the nature of the said Invention and the
manner in which it is to be performed so far as the said nature and
manner of performance relate to the "Improvements in Apparatus for
Steering Vessels," I declare that I claim as my said Invention,―
:.
Firstly. The application of steam power to apparatus for steering
vessels by means of "bevil wheel and double cone or other clutch
reversing gear" in combination with steering apparatus of the ordinary
or of any approved description, such gear being intended to be driven
by any convenient engine, whether itself provided with link or other
reversing gear or not, so provided and substantially in the manner above
set forth and as described and represented in the Drawings.
And, secondly. The application of steam power to apparatus for steer-
ing vessels by means of "bevil wheel and single cone or other clutch
engaging gear," in combination with steering apparatus of the ordinary
or of any approved description, such gear being intended to be driven
by means of an endless chain or belt from a steam winch or crano or
engine provided with link or other reversing gear.
To the improvements or that part of the Invention intended and
comprised by the following words extracted from the title thereof,
namely, "and for shifting material therein and therefrom" I do not
now attach any great importance and do not advance any specific claim,
excepting in combination with that part which relates to the "improve-
ments in apparatus for steering vessels " above set forth and described.
But my intentions were the application of steam power and that the
apparatus constructed as in Sheet No. 1 of the Drawings might have.
added or appended thereto additional bevil wheels and friction clutch
and break so as to control a winding apparatus driven from or by the

page_text: bevil wheels for the purpose of raising ashes from the hold or moving
goods or materials into or out from the vessel.
In witness whereof, I, the said George Edward Casebourne, have
hereunto set my hand and scal, this Fourteenth day of July, in
the year of our Lord One thousand eight hundred and seventy-
one.
GEORGE EDWARD CASEBOURNE. (L.S.)
