IMPROVEMENTS IN SHIPS' AND OTHER PUMPS
Year: 1853

page_text: LETTERS PATENT to Charles Ramsay, of North Shields, Brass
Founder, for the Invention of "IMPROVEMENTS IN SHIPS' AND OTHER
PUMPS."
Sealed the 19th May 1854, and dated the 22nd November 1853.
PROVISIONAL SPECIFICATION left by the said Charles Ramsay at
the Office of the Commissioners of Patents, with his Petition, ou
the 22nd November 1853.
I, CHARLES RAMSAY, of North Shields, Brass Founder, do hereby
declare the nature of the Invention "IMPROVEMENTS IN SHIPS' AND OTHER
PUMPS to be as follows:-
This Invention consists of a peculiar combination of parts, by which
a more advantageous construction of pump is obtained than those
heretofore used. For this purpose a horizontal cylinder or barrel is
employed, having a piston worked to and fro therein by a piston rod
put in motion by suitable power and gearing. At each end of the
cylinder or barrel is an opening for the passage of water (into and out)
as the piston moves from and to the ends of the cylinder or barrel. At
the upper end of the suction pipe there is a divided valve box, one

page_text: chamber of which communicates with one end, and the other chamber
communicating with the other end of the cylinder or barrel. The
valves in this valve box open inwards, and there is a man-hole or covered
opening by which the valves can readily be got at, and there is also a
divided passage or outlet, one branch communicating with one end,
and the other branch communicating with the other end of the cylinder
or barrel, each branch being closed with a valve opening outwards, so
that when either of the branches are not delivering water it is closed
air tight.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Charles Ramsay in the Great Seal Patent Office
on the 22nd May 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, J,
CHARLES RAMSAY, of North Shields, Brass Founder, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of November in
the year of our Lord One thousand eight hundred and fifty-three, in the
seventeenth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said Charles Ramsay, Her special
licence that I, the said Charles Ramsay, my executors, administrators,
and assigns, or such others as I, the said Charles Ramsay, my execu-
tors, 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
SHIPS AND OTHER PUMPS," upon the condition (amongst others) that I,
the said Charles Ramsay, by an instrument in writing under my hand
and seal, 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.

page_text: NOW KNOW YE, that I, the said Charles Ramsay, do hereby de-
clare the nature of the 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 (that is to say) :-
This Invention consists of a peculiar combination of parts, by which
a more advantageous construction of pump is obtained than those
heretofore used. For this purpose a horizontal cylinder or barrel is
employed, having a piston worked to and fro therein by a piston rod
put in motion by suitable power and gearing. At each end of the
cylinder or barrel is an opening for the passage of water (into and out)
as the piston moves from and to the ends of the cylinder or barrel. At the
upper end of the suction pipe there is a divided valve box, one chamber
of which communicates with one end, and the other chamber com-
municating with the other end, of the cylinder or barrel. The valves in
this valve box open inwards, and there is a man-hole or covered opening
by which the valves can readily be got at, and there is also a divided
passage or outlet, one branch communicating with one end, and the
other branch communicating with the other end, of the cylinder or
barrel, each branch being closed with a valve opening outwards, so that
when either of the branches are not delivering water it is closed air
tight.
Having thus stated the nature of my said Invention I will proceed to
describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1, shows a longitudinal section; Figure 2, a transverse
section; Figure 3, an external view; and Figure 4, an end view of a
pump constructed according to my Invention. a, a, is a horizontal
cylinder or barrel, in which the piston b, works, motion being com-
municated to the piston rod b', by any suitable power and gear. c, is a
passage or chamber formed on one side of the cylinder a; the passage c
communicates with each end of the cylinder a, so that water may pass
into and out as the piston moves from end to end of the cylinder; d, is
a divided valve box at the upper end of the suction pipe e, and d', d²,
are valves opening inwards, so as alternately to open and close the

page_text: passage of water from the suction pipe e, to each end of the cylinder a.
ff, is a divided passage or outlet for the water, one branch communi-
cating with one end and the other with the other end of the cylinder or
barrel a, each passage f, being closed by a valve f, opening outwards,
so that when either of the branches are not delivering water it is closed
air tight.
c', is a man-hole or covered opening by which the valves
d', d, can be readily got at, if required.
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I do not
confine myself to the precise details herein described, so long as the
peculiar character of my Invention be retained. But what I claim is,
the combination of parts constituting the valve chamber and water
passages to and from the cylinder a, as herein described.
In witness whereof, I, the said Charles Ramsay, have hereunto
set my hand and scal, this Twentieth day of May, in the year of
our Lord One thousand eight hundred and fifty-four.
Witness,
J. G. TONGUE.
CHARLES RAMSAY. (L.S.)
