Year: 1861

page_text: LETTERS PATENT to Richard Alfred Godwin, of 151, Newport Street,
Paradise Street, Lambeth, in the County of Surrey, for the Invention of
"IMPROVEMENTS IN PUMPS."
Sealed the 4th February 1862, and dated the 9th August 1861.
PROVISIONAL SPECIFICATION left by the said Richard Alfred Godwin
at the Office of the Commissioners of Patents, with his Petition, on the
9th August 1861.
I, RICHARD ALFRED GODWIN, of 151, Newport Street, Paradise Street,
Lambeth, in the County of Surrey, do hereby declare the nature of the
Invention for "IMPROVEMENTS IN PUMPS," to be as follows:-
This Invention has for its object improvements in pumps. For this purpose
I employ a cylinder mounted in a horizontal position and having a solid piston
fitted into it; near each end of the cylinder a suction pipe enters it, passing
through the side of the cylinder; each of these suction pipes is fitted with a
valve opening into the cylinder; the ends of the cylinder are closed, and the
piston rod is worked through a stuffing box in one of the ends; and through
the ends of the cylinders the exit passages are formed; these are fitted with
valves opening outward; these valves are kept as low down as possible to
allow the whole of the water the cylinder contains to run out. In some cases
I make the whole of the ends or covers of the cylinder open as exit valves in
order to give free passage to the water; and in order that the piston rod may
not interfere with the action of the end or valve through which it passes I
cause the said rod to work through a stuffing box carried by a bar passing
from side to side of the cylinder, and the end or valve has a circular hole cut
in it large enough to pass the piston rod freely, and when the end closes the

by the said Richard Alfred Godwin in the Great Seal Patent Office on

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ALFRED GODWIN, of 151, Newport Street, Paradise Street, Lambeth, in the
County of Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of August, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Richard Alfred Godwin, Her special licence that I, the said Richard
Alfred Godwin, my executors, administrators, and assigns, or such others as
I, the said Richard Alfred Godwin, 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 "IMPROVE-
MENTS IN PUMPS," upon the condition (amongst others) that I, the said Richard
Alfred Godwin, 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 Richard Alfred Godwin, do hereby
declare 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 has for its object improvements in pumps. For this purpose
I employ a cylinder mounted in a horizontal position and having a piston
fitted into it. Near each end of the cylinder a suction pipe enters it, passing
through the side of the cylinder; each of these suction pipes is fitted with a
valve opening into the cylinder. The ends of the cylinder are closed, and the
piston rod is worked through a stuffing box in one of the ends; and through
the ends of the cylinders the exit passages are formed; these are fitted with

page_text: valves opening outward; these valves are kept as low down as possible to
allow the whole of the water the cylinder contains to run out. In some cases
I make the whole of the ends or covers of the cylinder open as exit valves in
order to give free passage to the water; and in order that the piston rod may
not interfere with the action of the end or valve through which it passes
I
cause the said rod to work through a stufling box carried by a bar passing
from side to side of the cylinder; and the end or valve has a circular hole cut
in it large enough to pass the piston rod freely, and when the end closes, the
edges of the hole in the centre come against a ring around the stuffing box,
and so make a tight joint.
Having thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows a vertical section of a pump (constructed according to my
Invention; and Figure 2 shows a transverse section of the pump barrel or
cylinder and of one of the branch suction pipes.
a, a, is the barrel or cylinder of the pump, which is fixed in a horizontal
position in a suitable framing; b is the piston, c, the piston rod, which works
through a stuffing box d at one end of the barrel or cylinder of the pump. The
openings through which the water passes into and from the pump barrel or
cylinder are made at the lower side of and at the ends of the cylinder or barrel,
as shewn; e, e, are the outlet valves, which are hung, by preference, at their
upper sides, and rest, when shut, on inclined seats formed at the outlets or
openings f, f, of the barrel or cylinder of the pump, and such valves c, e, open
outwards; 9, 9, are two branch suction pipes, which are connected to the
descending suction pipe h, which has a retaining valve j, as shown; i, i, are
the two inlet valves in the branch suction pipes g; these valves are hung, by
preference, at their upper parts, and they shut down on inclined seats parallel,
or nearly so, with the seats of the outlet valves e, c.
The peculiarity of my Invention consists in the mode of applying the valves and
the valve seats to a horizontal cylinder or barrel of a pump, as herein explained.
In witness whereof, I, the said Richard Alfred Godwin, have hereunto
set my hand and seal, this Eighth day of February, in the year of our
Lord One thousand eight hundred and sixty-two.
RICH. A. GODWIN. (L.S.)
