Year: 1868

page_text: LETTERS PATENT to George Graveley, of Bow, in the County of
Middlesex, Engineer, for the Invention of "IMPROVEMENTS IN STEAM
PUMPS AND OTHER ENGINES ACTUATED BY STEAM OR OTHER MOTIVE FLUID, AND
IN COMBINING SEA WATER DISTILLING APPARATUS WITH STEAM PUMPING AND
PROVISIONAL SPECIFICATION left by the said George Graveley at the
Office of the Commissioners of Patents, with his Petition, on the
6th October 1868.
I, GEORGE GRAVELEY, of Bow, in the County of Middlesex, Engineer,
do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
STEAM PUMPS AND OTHER ENGINES ACTUATED BY STEAM OR OTHER MOTIVE FLUID
AND IN COMBINING SEA WATER DISTILLING APPARATUS WITH STEAM PUMPING AND
STEAM COOKING APPARATUS," to be as follows:-
The first part of my Invention relates to an improved arrangement
of valve for admitting steam or other motive fluid to and exhausting
the same from the cylinders for actuating pumps or other purposes
For this purpose I employ a crank or bent arm or excentric for working
the slide valve, the crank or bent arm being preferably the axle of
Pic 877

page_text: a fly wheel which is actuated by a rod connected with the piston
rod of the cylinder. As the fly wheel rotates its cranked axle moves
the slide, thereby opening the supply and exhaust ports at the proper
times.
The second part of my Invention consists in an improved combination
of steam pump and sea water distilling apparatus. The cylinder before
described is worked with steam generated from sea water, and the
piston rod works the plunger of a pump. The piston rod is connected
by a pin or crosshead with the plunger rod of a smaller pump for
feeding the boiler. The two pump barrels are surrounded with a worm
or coil of piping, and the whole is contained in a box or case. The
exhaust pipe, from the steam cylinder communicates with the worm,
and steam is also led from the boiler directly to the worm. The larger
pump draws in sea water from a tank or otherwise and discharges it
into the box, while the smaller pump draws water from the box to
feed the boiler. The water in the bex condenses the steam in the
worm and the fresh water resulting from the condensation after passing
hrough a filter or purifier is drawn off. A nozzle is fitted to the box
to discharge water for any purpose required. The smaller pump may
be dispensed with when other means are adopted for feeding the
boiler..
The third part of my Invention consists in an improved combination
of the sea water distilling with steam cooking apparatus. For this
purpose I lead steam generated from sea water into and through one
or more hollow globes or other hollow vessels suitable for being placed
in casks or other vessels in which the food, say rice, to be cooked is
placed. The steam entering the hollow globes which are surrounded
by the food effects the cooking of the food and at the same time
becomes partly condensed before reaching the condenser and purifier.
SPECIFICATION filed in pursuance of the conditions of the Letters:
Patent, and of an Order of the Lord Chancellor, by the said George
Graveley in the Great Seal Patent Office on the 27th April, 1869.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
GRAVELBY, of Bow, in the County of Middlesex, Engineer, send
greeting.

Letter Patent, bearing date the Sixth day of October, in the year
of our Lord One thousand eight hundred and sixty-eight, in the
thirty-second year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said George Graveley, Her special
licence that I, the said George Graveley, my executors, administrators,
and assigns, or such others as I, the said George Graveley, 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
STEAM PUMPS AND OTHER ENGINES ACTUATED BY STEAM OR OTHER MOTIVE FLUID,
AND IN COMBINING SEA WATER DISTILLING APPARATUS WITH STEAM PUMPING
AND STEAM COOKING APPARATUS," upon the condition (amongst others)
that I, the said George Graveley, 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 on or before the
Twenty-seventh day of April One thousand eight hundred and sixty-
nine.
NOW KNOW YE, that I, the said George Graveley, 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 accompanying
Drawings, that is to say:-
The first part of my Invention relates to an improved arrangement of
valve for admitting steam or other motive fluid to and exhausting the
same from the cylinders for actuating pumps or other purposes. For
this purpose I employ a crank or bent arm or excentric for working
he slide valve, the crank or bent arm being preferably the axle of a fly
wheel, which is actuated by a rod connected with the piston rod of the
ylinder. As the fly wheel rotates its cranked axle moves the slide,
hereby opening the supply and exhaust ports at the proper times.
The second part of my Invention consists in an improved combination
f steam pump and sea water distilling apparatus. The cylinder before
escribed is worked with steam generated from sea water, and the piston

page_text: rod works the plunger of a pump. The piston rod is connected by a pin
or cross head with the plunger rod of a smaller pump for feeding the
boiler. The two pump barrels are surrounded with a worm or coil of
piping, and the whole is contained in a box or case; the exhaust pipe
from the steam cylinder communicates with the worm, and steam is also
led from the boiler directly to the worm. The larger pump draws in sea
water from a tank or otherwise, and discharges it into the box, while the
smaller pump draws water from the box to feed the boiler. The water
in the box condenses the steam in the worm, and the fresh water result-
ing from the condensation after passing through a filter or purifier is
drawn off. A nozzle is fitted to the box to discharge water for any
purpose required. The smaller pump may be dispensed with when other
means are adopted for feeding the boiler.
The third part of my Invention consists in an improved combination
of the sea water distilling with steam cooking apparatus. For this
purpose I lead the steam generated from sea water into and through one
or more hollow globes or other hollow vessels suitable for being placed
in casks or other vessels in which the food, say rice, to be cooked is
placed. The steam entering the hollow globes which are surrounded by
the food effects the cooking of the food, and at the same time becomes
partly condensed before reaching the condenser and purifier.
In order that my Invention may be fully understood I proceed to
describe the same with reference to the accompanying Sheet of
Drawings.
Figure 1 is a section of my improved valve through the line A, B, of
Figure 3; Figure 2 is a sectional plan through the line C, D, of Figure 3,
showing my improved combination of steam pump
and sea water
distilling apparatus; Figure 3 is a vertical section and Figure 4 a side
elevation likewise showing the said combination as well as my improved
valve.
Figure 5 is a vertical section showing my improved combination of
sea water distilling and steam cooking apparatus.
Figure 1 is drawn to twice the scale of Figures 2, 3, and 4.
a is the steam cylinder, and 6 the piston of the same; c is the steam
supply, and d the exhaust pipe of the cylinder; e is the port commu-
nicating with the lower end of the cylinder a below the piston b; and f
is the port communicating with the upper end of the cylinder above the

page_text: piston; these are the only two ports in the cylinder; g is the slide valve
for covering and uncovering the ports e and f at the proper times; this
slide valve is formed with a slotted passage h to receive the crank or bent
portion i of the axle k of a fly wheel ; this wheel is rotated by a rod m
attached by a connection n to the piston rod o, so as to move simultaneously
therewith; the fly wheel therefore makes one revolution for every up-and-
down stroke of the piston. In the position of the parts seen in Figure 3
the piston is at the lower end of the cylinder, and the slide valve covers
both the ports, the fly wheel continuing to revolve shifts the valve through
the action of the crank i so as to open the port e to the supply c, and-the
port to the exhaust d; the up stroke of the piston is thus produced, and
the valve is then again shifted to the other side, thereby reversing the
ports, that is to say, opening the port to the exhaust and the port ƒ to
the supply, and so on.
It will be understood that my mode of arranging and operating the valve
is applicable to engines other than steam pumps, and whether actuated by
steam or by other motive fluid.

I now proceed to describe the manner in which I combine sea water
distilling apparatus with a steam pump.
The steam cylinder a for
working the pump p is actuated by steam generated from sea water, and
the piston rod o works or constitutes the plunger of the pump. q is a
smaller pump, the plunger r of which is connected to the plunger o, as
shown, so that the two plungers work together. This pump q is for
feeding the boiler, and may be dispensed with if not required for that
purpose. s, 8, are the valves of the larger pump, and t, t, those of the
smaller pump; these valves being of ordinary construction and arrange-
ment do not require further description. The two pump barrels and
are surrounded with a worm or coil of piping u, and the whole is contained
in a box or case v. The exhaust pipe d from the cylinder a communi-
cates with the worm u, and steam is also led directly to the worm by
the pipe w. The larger pump p draws.in sea water from a tank or other-
wise by the pipe x, and discharges it into the box »; the smaller pump
draws water from the box and discharges it through a pipe to the boiler
or otherwise. The water in the box v condenses the steam in the worm u
and the fresh water resulting from the condensation passes into a filter
or purifier y, from which it may be drawn off at 2. j is an overflow for
the box v.
I now proceed to describe the manner in which I combine sea water

page_text: distilling apparatus with steam cooking apparatus E. Figure 5 is a
hollow globe or vessel, into which steam generated from sea water is led
by a pipe F; G is a pipe to couvey the steam from the globe to a con-
denser. The globe E is placed in a cask or other vessel H, as shown,
into which the food to be cooked is placed. The steam entering the
globe E effects the cooking of the food, and is at the same time partly
condensed before passing off by the pipe G to the condenser.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim,-
First. Fitting steam pumps and other engines actuated by steam or
other motive fluid with a valve constructed and operated substantially as
herein-before described and represented in Figures 1, 3, and 4 of the
accompanying Drawings.
Second. Combining steam pumps and sea water distilling apparatus,
substantially in the manner herein-before described and represented in
Figures 2, 3, and 4 of the accompanying Drawings.
Third. The combination with sea
with sea water distilling apparatus of
apparatus for cooking, constructed and acting substantially as herein-
before described with reference to Figure 5 of the accompanying
Drawings.
In witness whereof, I, the said George Graveley, have hereunto set
my hand and seal, this Twenty-sixth day of April, Oue thousand
eight hundred and sixty-nine.
