IMPROVEMENTS IN SHIPS AND OTHER PUMPS, IN ANCHORS, AND IN PROPELLING VESSELS
Year: 1850

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
GREENWAY, of Green Street, Grosvenor Square, in the County of Middlesex,
send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Nineteenth day of
June, One thousand eight hundred and fifty, in the thirteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Charles Greenway, my exors, adñors, and assigns, Her especial licence,
full
power, sole privilege and authority, that I, the said Charles Greenway, my
exors, adiñiors, and assigns, or such others as I, the said Charles Greenway,
my exors, admiors, or assigns, should at any time agree with, and no others,
from time to time and at all times during the term of years therein expressed,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "IMPROVEMENTS
IN SHIPS AND OTHER PUMPS, IN ANCHORS, AND IN PROPELLING VESSELS;" in which
said Letters Patent is contained a proviso that I, the said Charles Green-
way, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, by an instrument in
writing under my hand and seal, to be inrolled in Her said Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Charles Greenway, do hereby declare that the nature of my said Invention,

page_text: and the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had to
the Drawing hereunto annexed, and to the figures and letters marked thereon
(that is to say):
-:
My Invention relates, first, to an arrangement of valve suitable for ship and
other pumps; and, secondly, my Invention relates to a mode of constructing
anchors.
And in order that the Invention may be fully understood I will proceed to
describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a plan, and Figure 2 a section of a valve, with its seating,
for ship and other pumps, arranged according to my Invention. Figure 8
shows a plan and section of the valve seating separately. Figures 4 and 5
show the parts of the valve; a, a, is the seating, which is ground or other-
wise fitted to receive the parts of the valve, which are guided in their
movement by their stems passing through the bridge a', as is well under-
stood in arranging other pump valves and seats. The valve in this instance
consists of two parts, b, c, but other numbers of parts may be employed. The
object being to increase the waterway and facilitate the action, the part b
of the valve is perforated and ground, as shewn at b, to fit tightly into the
seat a. The part b is also formed with a seat at b² to receive the part c, which
is a plain disc with an edge ground to fit close in the seating of the valve b,
and it has a stenn c', which passes through and is guided by the hollow stem b³
of the part 6. In causing water or other fluid to flow through the valve the
two parts b, c, will be separated, and the liquid divided into two streams, one
passing between the parts a and b, and the other between the parts b and c.
I would however state that I do not confine myself to dividing such valves
into but two parts, as it will be evident that in like manner may valves be
divided into three or other number of parts, by which three or other number
of distinct streams may be obtained.
I will now describe the second part of my Invention, which consists of
forming anchors by cutting or stamping out of sheet metal a series of parts
each of the form of an anchor, in place of forming anchors of bar iron, and by
piling, welding, and forging, as heretofore. Figure 6 shows a side view, and
Figure 7 an edge view of an anchor constructed according to my Invention.
Figure 8 shews the central, and Figures 9 and 10 show thin portions of an
anchor, each stamped or cut out of plates of iron. I prefer to form the
parts a, b, c, by stamping out of sheet iron. The parts b', c', (which are to

page_text: form parts of the flukes) when cut are to be of the form indicated by the
dotted lines in Figures 9 and 10; they are then to be turned up, as shewn
by the section Figure 11, and so that when the parts a, b, c, are together,
as shewn by the Figures 6 and 7, they will lie close together, and aid to
support each other and form the fluke. Although in the Drawing I have
shewn the anchor composed of only five parts, I do not confine myself to
that number, as the anchor may be composed of other numbers of plates.
In forming what I call a portable anchor I combine a suitable number
of such plates together, retaining them in their relative position by screws
and nuts d, d, d, or other suitable fastenings. When not in use, or when
they are required to be moved from one locality to another, the screws
and nuts or other suitable fastenings used may be removed, and the plates
separately removed or stowed away. In thus combining sheets of metal
to form portable anchors I prefer to apply between the sheets of iron
then sheets of zinc of the same form, which will serve to counteract corosion.
And although I have described the palms as being formed by the binding
over of the parts b', c', I sometimes cut the plates without those parts, and
afterwards apply separate palms, which may be bolted or otherwise fastened
on to the anchor. I also employ sheet iron as a means of making solid
anchors. For this purpose, having formed the separate parts from sheet
iron, as above described, and temporarily hooped or bound them together,
I place them in a furnace till they are at a welding heat, and then by
means of hammering I weld the separate plates into one solid mass; or,
in place of welding the parts together by hammering, I combine the soparate
plates together when at a welding heat by compression by means of suitable
dies or tools actuated by a steam hammer.
Having thus described the nature of my said Invention, and the manner
in which the same is to be carried into effect, I would have it understood that
I do not confine myself to the precise details shewn and described, so long
as the peculiar character of either part of my Invention be retained. But what
I claim is,-
First, the mode herein described of constructing valves for ships' and other
pumps; and, secondly, I claim the mode herein described of constructing
anchors.
I witness whereof, I, the said Charles Greenway, have hereunto set my
hand and seal, this Eighteenth day of December, in the year of our
Lord One thousand eight hundred and fifty.

page_text: In the Matter of a Patent granted to Charles Greenway, of Green
Street, Grosvenor Square, in the County of Middlesex, for his
Invention of "Improvements in Ships' and other Pumps, in Anchors,
and in Propelling Vessels," bearing date at Westminster, the Nine-
teenth day of June, One thousand eight hundred and fifty.
DISCLAIMER and Memorandum of Alteration proposed to be entered by
Charles Greenway with the Clerk of the Patents of England, pursuant to
an Act passed in the fifth and sixth years of the reign of His late
Majesty King William the Fourth, intituled an "Act to amend the
Law touching Letters Patent for Inventions."
¿c
I, the said Charles Greenway, do declare, that since I obtained the said
Letters Patent I have discovered that the Invention which was to have
been described under that part of the title which is contained in the following
words, and in propelling vessels," has not that degree of novelty it was
supposed to possess at the time of taking out the said Letters Patent, for
which reason I am desirous to, and do hereby, disclaim all that part of the
title which is contained in the following words, "and in propelling vessels;" and
in order to make sense of the title then remaining, I alter it by introducing
the word and between the words "pumps in," so that the title will be as
follows: "Improvements in Ships' and other Pumps, and in Anchors."
In witness whereof, I, the said Charles Greenway, have hereunto set my
hand and seal, this Eighteenth day of December, in the year of our
Lord One thousand eight hundred and fifty.
CHARLES (L.S.) GREET AI.
To the Clerk of the Patents of England.
This is to certify, that Charles Greenway, of Green Street, Grosvenor
Square, in the County of Middlesex, has applied to me for leave to enter with
you the above-written Disclaimer of part of the title of a certain Invention for
which Letters Patent were granted to him under the Great Seal, bearing date
the 19th day of June 1850; and on considering the said application, and no
objection having been made to the same, I have accordingly granted leave
to the said Charles Greenway to file his said Disclaimer, pursuant to the

page_text: Statute passed in the 6th year of the reign of His late Majesty, entitled An
Act to amend the Law touching Letters Patent for Inventions.
