of Liverpool, in the County of Lancaster, Engineers, for the Invention of
"IMPROVEMENTS IN STEAM APPARATUS FOR SHIPS' USE, PART OF WHICH

page_text: This arrangement consists in the first place
tank constructed in the following manner:-It is preferred for ships'
use that
the boiler should be of the vertical or upright form, the fire-box being formed
by a series of annular cones, the first cone commencing at the lower end of
fire-box, & from the position when the boiler rests on the tank, standing at an 5
angle of 45° to the horizon or thereabouts, and contracting the fire-box at the
inner point equal to the distance that it may be thought necessary to carry the
first cone; from the edge of this cone and back at right angles or there-
abouts towards the shell of boiler are attached the second cones, these cones
being continued as far upwards as the fire-box may be determined on, and 1
ending by one cone into size of chimney aperture. The chimney may also be

.
to that of the other. On these parallel faces tubes may be applied across the
fire-box. This arrangement gives a large amount of heating surface with an
immensely strong boiler, the steam being well liberated at all its parts when 1
the heat acts on directly. Under the boiler and on the deck of ship we place
a water supply tank; this tank is constructed with a space for ash-pit, the
heat from boiler fire is isolated from the deck by means of a steam or water
space between ash-pit and bottom of tank. The boiler is attached to the
tank, ship's deck, or foundation, as the case may be, by brackets rivetted to
the outer shell of boiler, and bolted through the tank tubes. The blow-off
cock, back-pressure valve for feed, & scum cock are connected in one at
bottom of boiler. The safety valve is enclosed in case bolted to side of boiler,
and has double branch attached, one with steam acting on valve, the other to
attach steam pipe for engine or condensor. It is also intended to have a
small pipe connected with water in boiler to take away any water that may
pass in with the steam on condensing in its chamber. The engine it is
preferred to attach by wrought-iron brackets to the side of the boiler, and to
economize space it is preferred that its shaft should pass through the boiler,
& to be isolated from the boiler in the following manner-to pass through a
tube, which tube passes through one of the tubes proposed to be placed across
the fire-box. The engine may have either oscillating or fixed cylenders, or a
single cylender.
Our arrangement of valve or reversing motion in our oscillating engines is
carried out in the following manner :-On the ordinary crank pin and imme-
diately over the valve spindle is fixed a crank. On one end of this crank, near
the centre of the shaft, a curve is formed corresponding with back & front
throw of valve for stopping and reversing the engine. In this curve a pin
attached to a lever slides, by which the reversing of the engine & the expan

page_text: sion of the steam is conducted. On the lower end of rod attached to the
before-mentioned pin is a slotted segment of a circle struck from centre of
oscillation of the cylender to the centre of pin in valve spindle. This pin,
working in a bush in the before-mentioned segmental slot, takes the curve
5 formed by the oscillation of cylender out of the motion of valve, the position
of segment being guided by a link.
Another arrangement of motion for working the valve may be adopted,
which is carried into effect in the following manner :-At a point set off on each
side of the cylender trunnions a fixed pin is placed, on this pin a link with a
o double gab or slot is fixed, the opposite end of link being connected to a pin on
valve spindle. On the cylender being put into motion this link gives motion
to the valve spindle & valve, by taking it off pin & transferring it to pin on
the opposite side of trunnion the engine will be reversed. The same may be
carried out by the valve spindle pin working in a slot to represent the motion
5 of link, the slot being moveable, which would reverse & stop the engine.
The feed pump it is preferred should be placed in the tank, as the water
being nearly heated to boiling point by the combined action of the down-
ward heat from fire and the exhaust into tank, by placing the barrel of pump
below the water in tank more certainty of action is ensured, as the steam from
the water when heated makes the action of the pump uncertain. This pump
can be applied to pump the water from sea into tank, or from tank into the
boiler when required. In the engines in which the crank shaft passes through
the boiler a pair of brackets are rivetted on the boiler parallel to the crank
shaft; on these brackets are bolted pedestals, on which a strong shaft works with
differential or other spur gearing from main shaft of engine; this shaft passes
through the deck house on each side of the ship; on this shaft are placed
gipseys or conical barrels for hauling ship, lifting anchor, taking out heavy
machinery, hauling up yards, or any other heavy work required. In some
cases a V or rope wheel with sufficient griping power is attached where a rope
may be attached for working windlass direct or driving any other work. In
working the windlass in this manner we can make use of the ordinary
arrangement with pawl or frictional gearing. We fix a shaft on which is
keyed a V or rope wheel to the bit beads, or in some other convenient manner;
this V or rope wheel is driven by a rope from the shaft passing through the
sides or from the inside of deck house. On this shaft, connected with windlass
gearing, is keyed a pinion, which pinion is geared into a spur wheel, and by
means of a fixing on the bits a differential stroke is acquired with links or
rods to the ordinary rocking motion frames of windlass; the anchor can be got

For discharging cargo we place a winch or hoist driven as in the previous case
with a rope or V wheel, or otherwise, direct from engine shaft; this winch has a
frictional contact wheel, which it is preferred should be of cast iron, with a corru-
gated surface in the direction of its motion, which wheel is driven by another
wheel, which it is preferred should be made of compressed paper bound in iron,
and fixed on first motion shaft of winch. This wheel is also corrugated to corre-
spond with the wheel previously mentioned. They may be also worked in
contact without the corrugated surfaces, but
greater when the corrugated surfaces are used.
which the barrel is fixed for chain a frictional iron wheel is attached bearing
in a steading bush. This bush is moved by a hand lever.
This bush is moved by a hand lever. On moving the
lever this bush brings the wheel in contact with the frictional surface of small
wheel driven by the engine, thereby lifting any weight that may be attached by
the chain to the barrel. On slightly depressing it the lever of the winch or
barrel will lower the weight, but on still further depressing it the wheel will
come into contact by the introduction of a third friction wheel.

which is attached to the sides of the winch frame by adjusting screws, one
lever lifting, lowering, and stopping the ascent or descent of the weights to be
lifted. On the barrel shaft of winch and outside of frame we attach a pinion
which gears into another wheel keyed on a shaft which passes along on each
side of the back of this winch. On this shaft can also be placed gipseys for
any heavy work, or revolving clams for dragging chain or hauling out of
lockers, this arrangement only being required when from want of room or from
some other cause the shaft through the deck house is not fixed. The
are also worked by a V wheel on engine shaft, over which a rope is passed, a
corresponding wheel of sufficient diameter being placed on the shaft driving
pumps, or holes may be made through the arms of the fly wheels usually
applied to ships' pumps, and dogs or loose V's attached with bolts or otherwise
thereto. For the purpose of taking up the slack of these ropes when in
motion we attach a pulley to a double lever. This lever has circular eyes on
the lower end through which the shaft, having a V wheel fixed on it, passes
between each arm of lever the V wheel on shaft and rope wheel for tightening
The pulley for tightening rope running loose on a pin
between the arms of the levers bears down or up as the case may be in the
direction of the circumference of the V wheel, thus taking up the slack of the
rope are fixed.

The pumps we prefer to use in
connection with these arrangements are those for which we received Letters
Patent dated 30th April 1859, No. 1082, but we can adapt this gear to any
other pumps.
Another part of this Invention is our improved evaporator or regenerative
still for producing pure sparkling fresh water from sea water or foul water.
Our Invention consists of first boiling off a large portion of the water of
condensation, converting it into steam at lower temperature than the boiling
point, & causing the steam so evaporated to pass into the condensing tubes
O along with the original steam from the main boiler. Third for keeping sea
water in evaporating part of condenser at a uniform height, & clearing out
the brine deposited by the evaporation of the water without any attention from
the party in charge. For preventing priming or boiling over of the water.
For producing a larger quantity of water than usual from ordinary condensors,
and aerating, boiling, & condensing the water in the same cylender for a new
method of filtering, producing clear, bright, and pure water. This portion of
the apparatus consists of the following parts:-A base or plinth cast or made
hollow, in which the cistern or case containing the filtering materials are
placed; a cylender or case in which the boiling, condensing, and aerating and
circulating of the water of condensation is carried on. A worm or coil, or
or more than one worm or coil, or a series of tubes, circular or quadrilateral, is
or are placed within the cylender. On the top or outside of the cylender and
connected directly with the steam pipe from the boiler is attached a modifica-
tion of Giffard's injector. The steam from the boiler blowing directly through
this injector, and forming a partial vacuum in a chamber surrounding the
injector, which cavity or chamber is connected by pipes or otherwise to the
top of the cylender or case, enters into the space between the water & cover,
which pipes may have a means of regulating the admission of the steam into
injector, and thence into condensing tubes. A partial vacuum will be formed
on the surface of the water in the cylender causing it to liberate its steam at a
ower temperature, drawing it off to condensor, and ensuring the water in
ylender from priming or boiling up; a small tap may be placed on this cover
o regulate the admission of air into the space above the water if required.
The water of condensation is circulated around the condensing tubes by means

ensed water in the tubes enters the filter; its exit is regulated by a pipe

previously
from the steam in its descent through the tubes or coils, and, as
stated, boiling off by aid of the heat and partial vacuum a portion of the
water of condensation, which is drawn up by the injector, and, as
previously
explained, passes down through the coils or tubes, partially retreating the water
and passing out of condensor along with the steam injected from boiler. The
pump it is preferred to attach directly to side of cylender or filter case with
suitable passages cast on ditto, for conveying and distributing the water to the
point required. That portion of the cylender or case in which the filtering
process is conducted is preferred to be of a rectangular form open at one side
so that the filter be drawn in and out if required, doing away with the necessity
for breaking any of the joints connected with this portion of the apparatus if
required to be seen for any purpose.
The filter. Our filtering composition is formed by combining in the manner
herein-after stated furnace coke, animal or vegetable charcoal ground very
fine, white river or sea sand (well washed) and coarse gravel or ground glass.
First, we fix about three inches from the bottom of the vessel which is to con-
tain the filter a false bottom or perforated plate; on this is placed a layer
of coarse gravel or ground glass, after which we put in a layer of white sea
or river sand (well washed), about one inch in thickness and press it carefully
down to the gravel so that it may be firmly set; next a layer two inches or
thereabouts in thickness of furnace coke ground very fine and well washed,
which we beat down until it is perfectly solid; we next put in a layer of
very fine animal or vegetable charcoal, which is also beat very solid, and over
this is placed another layer of furnace coke also beaten down as before; we
then put in a thin layer of coarse gravel or ground glass. To keep the whole
composition firmly bound together we fasten on the top
cement another perforated plate. The vessel in which we place the filter may
be made of iron, slate, wood, or earthenware. The water condensed from
the steam is admitted at the top of the filter and percolates through the
filtering medium and issues perfectly pure through the pipe or cock at the
bottom of the vessel, and is led off to tanks or in any direction as may
required through a tube, pipe, or otherwise.

PROVEMENTS IN STEAM APPARATUS FOR SHIPS' USE, PART OF WHICH IMPROVEMENTS
IS APPLICABLE TO OTHER PURPOSES," upon the condition (amongst others) that
we, the said William Winstanley and Joseph Kelly, our executors or admi-
nistrators, by an instrument in writing under our, or their, or one of their

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 we, the said William Winstanley and Joseph
Kelly, do hereby declare the nature of our said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement :-
This Invention consists in the first place of a fixed steam engine boiler and
ank constructed in the following manner:-It is preferred for ships' use that
the boiler should be of the vertical or upright form, the fire-box being formed
y a series of annular cones, the first commencing at the lower end of fire-box
und from the position when the boiler rests on the tank standing at an angle
or thereabouts of 45° to the horizon, and contracting the fire-box at the inner
oint equal to the distance that it may be thought necessary to carry the first

cone; from the edge of this cone and back at right angles or thereabouts
towards the shell of boiler are attached the second cones, these cones being
continued as far upwards as the fire-box may be determined on, and ending
by one cone into size of chimney aperture; the chimney may also be made in
In this form of boiler the face of cone is parallel to that
of the other. On these parallel faces tubes may be applied across the fire-box.
This arrangement gives a large amount of heating surface with an
strong boiler, the steam being well liberated at all its parts when the heat acts
on directly. Under the boiler, and on the deck of the ship, we place a water
supply tank; this tank is constructed with a space for ash-pit. The heat
from boiler fire is isolated from the deck by means of a steam or water space
between ash-pit and bottom of tank. The boiler is attached to the tank,
ship's deck, or foundation, as the case may be, by brackets rivetted to the
outer shell of boiler and bolted through the tank tubes. The blow-off cock,
valve for feed, and scum cock, are connected in one at bottom
of boiler. The safety valve is enclosed in case bolted to side of boiler, and
bas double branch attached, one with steam acting on valve, the other to
attach steam pipe for engine or condenser. It is also intended to have a small
pipe connected with water in boiler, to take away any water that may pass in
with the steam on condensing in its chamber. The engine it is preferred to
attach by wrought-iron brackets to the side of the boiler, and to economize
space it is preferred that its shaft should pass through the boiler, and to be
isolated from the water in the following manner,-to pass through a tube, which
tube passes through one of the tubes proposed to be placed across the fire-box.
The engine may have either fixed or oscillating cylinders, or a single cylinder.
Our arrangement of valve or reversing motion in our oscillating engines is
carried out in the following manner :-On the ordinary crank pin and imme-
diately over the valve spindle is fixed a crank, on one end of this crank,
near the centre of the shaft, a curve is formed corresponding with back and
front throw of valve for stopping and reversing the engine. In this case a
pin attached to a lever slides, by which the reversing of the engine and the
expansion of the steam is conducted. On the lower end of rod, attached to
the before-mentioned pin, is a slotted segment of a circle, struck from the
centre of oscillation of cylinder to the centre of pin in valve spindle;
working in a bush in the before-mentioned segmental slot takes the curve
formed by the oscillation of cylinder out of the motion of valve, the position of
segment being guided by a link.
this pin
Another arrangement of motion for working the valve may be adopted.
which is carried into effect in the following manner:-At a point set off on

page_text: each side of the cylinder trunnions a fixed pin is placed; on this pin a link
with a double gab or slot is fixed, the opposite end of link being connected to
a pin on valve spindle on the cylinder being put into motion. This link gives
motion to the valve spindle and valve; by taking it off pin and transferring it
5 to pin on the opposite side of trunnion the engine will be reversed. The
same may be carried out by the valve spindle pin working in a slot to represent
the motion of link, the slot being moveable, which would reverse and stop the
engine. The feed pump it is preferred should be placed in the tank, as the
water being heated to nearly boiling point by the combined action of the
downward heat from fire and the exhaust into tank by placing the barrel of
pump below the water in tank more certainty of action is ensured, as the steam
from the water when heated makes the action of the pump uncertain. This
pump can be applied to pump the water from sea into tank or from tank into
the boiler when required. In the engines in which the crank shaft passes
through the boiler a pair of brackets are rivetted on the boiler parallel to the
crank shaft; on these brackets are bolted pedestals, in which a strong shaft
works with differential or other spur gearing from main shaft of engine. This
shaft passes through the deck house on each side of the ship. On this shaft
are placed gypseys or conical barrels for hauling ship, lifting anchor, taking out
heavy machinery, hauling up yards, or any other heavy work required. In
some cases a V or rope wheel with sufficient griping power is attached
where a rope may be attached for working windlass direct or driving any other
work. In working the windlass in this manner we can make use of the
ordinary arrangement with pawl or friction gearing. We fix a shaft, on
which is keyed a V or rope wheel, to the bit heads, or in some other con-
venient manner; this V or rope wheel is driven by a rope from the shaft
passing through the sides or from the inside of deck house; on this shaft,
connected with windlass gearing, a pinion is keyed, which pinion is geared
into a spur
wheel, and by means of a fixing on the bits a differential stroke is
acquired with links or rods to the ordinary rocking motion frames of windlass
the anchor can be got up, the hand lever of windlass remaining, and can be
made use of if required from adjustable pins on two disc plates, and are
connected.
For discharging cargo we place a winch or hoist driven as in the previous
case with a rope or V wheel or otherwise direct off engine shaft. This winch
has a frictional contact wheel, which it is preferred should be of cast iron with
a corrugated surface in the direction of its motion, which wheel is driven by
another wheel, which it is preferred should be made of compressed pape
bound in iron and fixed on first motion shaft of winch. This wheel is also

page_text: corrugated to correspond with the wheel previously mentioned. They may be
also worked in contact without the corrugated surfaces, but the frictional
contact will be greater when the corrugated surfaces are used. On end of the
spindle, in which the barrel is fixed for chain, a frictional iron wheel is attached
bearing steading bush; this bush is moved by a hand lever. On moving
the lever this bush brings the wheel in contact with the frictional surface of
small wheel driven by the engine, thereby lifting any weight that may be
attached by the chain to the barrel; on slightly depressing, the lever of the
winch or barrel will lower the weight, but on still further depressing it the
wheel will come into contact. By the introduction of a third friction wheel
the wheel can be made to hoist both ways without reversing the engine. The
break is attached to the sides of the winch frame by adjusting screws, one
lever lifting, lowering, and stopping the ascent or descent of the weights to be
lifted. On the barrel shaft of winch and outside of frame we attach a pinion
which gears into another wheel keyed on a shaft which passes along on each
side of the back of this winch. On this shaft can also be placed gypseys for
any heavy work or revolving clams for dragging chain or hauling out of lockers,
this arrangement being only required when from want of room or some
other cause the shaft through the deckhouse is not fixed. The pumps are
also worked by a V wheel on engine shaft, over which a rope is passed, a
corresponding wheel of sufficient diameter being placed on the shaft; driving
pumps or holes may be made through the arms of the fly wheels usually
applied to ships' pumps and dogs or loose V's attached with bolts or otherwise
thereto. For the purpose of taking up the slack of these ropes when in
motion we attach a pulley to a double lever; this lever has circular eyes on the 2
lower end, through which the shaft on which a V wheel is placed, the pulley
for tightening rope running loose on a pin between the arms of the levers, and
bear down or up, as the case may be, in the direction of the circumference.
of the V wheel, thus taking up the slack of the rope and increasing its hold
on the wheels.
The pumps we prefer to use in connection with these arrangements are
those for which we received Letters Patent, dated April Thirtieth, Oue
thousand eight hundred and fifty-nine, but we can adapt this gear to any other
pumps.

Another part of this Invention is our improved evaporator or regenerative S
still for producing pure sparkling fresh water from sea water or foul water,
which consists of, firstly, boiling off a large portion of the water of conden-
sation, converting it into steam at lower temperature than that boiling out, and
causing the steam so evaporated to pass into the condensing tubes along with

page_text: the original steam from the main boiler. Secondly, for keeping sea water in
evaporating part of condenser at a uniform height, and clearing out the brine
deposited by the evaporation of the water without any attention from the party
in charge. Thirdly, for preventing priming or boiling over of the water.
5 Fourthly, for producing a larger quantity of water than usual from ordinary
condensers, and aerating, boiling, and condensing the water in the same
cylinder; and, fifthly, for a new method of filtering, producing clean, bright,
and pure water.
This portion of the apparatus consists of the following parts:-A base or
0 plinth cast or made hollow, in which the cistern or case containing the filtering
materials are placed. A cylinder or case in which the boiling, condensing,
aerating, and circulating of the water of condensation is carried on.
A worm
er coil, or more than one worm or coil, or a series of tubes circular or
quadrilateral is placed within the cylinder. On the top or outside of the
cylinder, and connected directly with the steam pipe from the boiler, is
attached a modification of Giffard's injector, the steam from the boiler
blowing directly through this injector and forming a partial vacuum in a
chamber surrounding the injector, which cavity or chamber is connected by
pipes or otherwise to the top of cylinder or case, enters into the space between
the water and cover, which pipes may have a means of regulating the
admission of the steam into injector, and thence into condensing tubes. A
partial vacuum will be formed on the surface of the water in the cylinder,
causing it to liberate its steam at a lower temperature, drawing it off to con-
denser, and insuring the water in cylinder from priming or boiling up. A
small tap may be placed on this cover to regulate the admission of air into the
space above the water if required. The water of condensation is circulated
around the condensing tubes by means of one of our patent re-action pumps,
but any other description of pump will answer the purpose. This water enters
the cylinder at the lowest end, or near the point where the water that is con-
densed in the tubes enters the filter; its exit is regulated by a pipe cast on
the cylinder, or otherwise, which takes the water off from the cylinder at
about half its height or thereabouts on the side of the cylinder, so that a
portion of this water will rise around the top part of tubes, taking up the
heat from the steam in its descent through the tubes or coils, and, as
previously stated, boiling off by aid of the heat and partial vacuum a portion
of the water of condensation which is drawn up by the injector, and, as
previously explained, passes down through the coils or tubes, partially retreating
the water, and passing out of condenser along with the steam injected from
boiler. The pump it is preferred to attach directly to side of cylinder or filter

the filtering process is conducted is preferred to be of a rectangular form, open
with the necessity for breaking any of the joints connected with this portion 5
at one side, so that the filter be drawn in and out if required, doing away
of the apparatus if required to be seen for any purpose.
gravel,
Our filtering composition is formed by combining in the manner herein-after
stated furnace coke, animal or vegetable charcoal ground very fine, white river
or sea sand (well washed), and coarse gravel, or ground glass. First, about
three inches from the bottom of the vessel which is to contain the filter a false 1
bottom or perforated plate is fixed, on this is placed a layer of coarse gravel
or ground glass, after which we put in a layer of white sea or river sand (well
washed) about one inch in thickness, and press it carefully down to the
so that it may be firmly set; next a layer two inches or thereabouts in thick-
ness of furnace coke ground very fine, and well washed, which we beat down 1
until it is perfectly solid; we next put in a layer of very fine animal or
vegetable charcoal, which is also beat very solid, and over this is placed
another layer of furnace coke, also beaten down as before; we then put in
a thin layer of coarse gravel or ground glass. To keep the composition firmly
bound together we fasten on the top by bolts, screws, or cement another
perforated plate. The vessel in which we place the filter may be made of
iron, slate, wood, or earthenware. The water condensed from the steam is
admitted at the top of the filter, and percolates through the filtering medium,
and issues perfectly pure through the pipe or cock at the bottom of the vessel,
and is led off to tanks, or in any direction as may be required.
In order that our Invention may be the more readily seen and understood.
we have hereunto annexed Drawings illustrative of the same.

Having now fully described and ascertained the nature of this our said
Invention, and how the same may be carried into practical effect, we should
remark we do not confine ourselves to the precise details, dimensions, or
relative proportions of the several parts, but we wish it to be understood that
we claim the general arrangement and combination of the various parts of the
apparatus, substantially and in the manner and for the purposes herein-before
described and set forth, particularly the fresh water-producing apparatus, the
internal arrangement of steam boiler, the motion for working steam slide
valve of engine, the combination of condensing apparatus with steam engine,
circulating pump, feed pump, and filter, the application of injector arrange-
ment for boiling in vacuo, and the arrangement of filtering material, as
described.

Kelly, have hereunto set our hands and seals, this Twenty-ninth
