Year: 1864

page_text: LETTERS PATENT to William Edward Newton, of the Office for Patents,
66, Chancery Lane, in the County of Middlesex, Civil Engineer, for the
Invention of "IMPROVEMENTS IN PUMPS."-A communication from abroad
by Levi Peabody Dodge, of Newburgh, in the State of New York,
United States of America.
Sealed the 14th March 1865, and dated the 15th October 1864.
PROVISIONAL SPECIFICATION left by the said William Edward Newton
at the Office of the Commissioners of Patents, with his Petition, on the
15th October 1864.
I, WILLIAM EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane,
in the County of Middlesex, Civil Engineer, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN PUMPS," to be as follows:-
This Invention consists, firstly, in a novel construction and arrangement of
the chamber containing the inlet valves, and of the seats of the valves in a
double-acting pump. The cover of the valve chamber is formed by the flange
around the cylinder with the same joint, composed of two plane surfaces, as is
used to unite the cylinder and sole plate. This chamber is provided with a
small bonnet or cover so that the valves may be reached by the removal of
the small bonnet or cover without unseating the cylinder.
It consists, secondly, in a novel arrangement of the delivery valves and
their containing chamber and seats in relation to the air vessel and the
cylinder, whereby. the connection of the passages of the cylinder with the air
vessel, and that of the cylinder cover with the cylinder are made by joints

page_text: having their surfaces in the same plane, and the labour of facing the surfaces
of the joints is reduced. These valves are on or near the same plane as the
cover of the cylinder, and are also easy of access from above.
It consists, thirdly, in constructing the upper part of the air vessel with a
moveable cover, by removing which the delivery valves can be reached
without removing or disconnecting the air vessel or the delivery pipes leading
therefrom..
And it consists, finally, in a compound valve of india-rubber and leather of
novel construction, whereby the advantages of both of those materials are
obtained without the disadvantages of either. This valve is made of a disc of
sheet rubber to which a ring of leather is cemented, and a weight is attached
to the central part of the valve by means of a screw and washer..
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Edward Newton in the Great. Seal Patent Office
on the 15th April 1865.

EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the County
of Middlesex, Civil Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Fifteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-eighth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William Edward Newton, Her special, license that I, the said: William
Edward Newton, my executors, administrators, and assigns, or such others.
as I, the said, William, Edward Newton, 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. Kingdoni, of-Great
Britain and Ireland, the Channel Islands; and Isle of Man, an. Invention for.
"IMPROVEMENTS IN PUMPS," being a communication from abroad;. upon the.
condition (amongst others) that I, the said William Edward Newton, 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 William Edward Newton, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Drawing hereunto annexed, and to the
letters and figures marked thereon (that is to say):
This Invention consists, firstly, in a novel construction and arrangement of,
the chamber containing the inlet valves, and of the seats of the valves in a
double-acting pump. The cover of the valve chamber is formed by the flange
around the cylinder with the same joint, composed of two plane surfaces, as is,
used to unite the cylinder and sole plate. The valves may therefore be
reached on the removal of a small bonnet.
The Invention consists, secondly, in a novel arrangement of the delivery
valves and their containing chamber and seats, in relation to the air vessel and
the cylinder, whereby the connection of the passages of the cylinder with the
air vessel, and that of the cylinder cover with the cylinder, are made by joints.
having their surfaces in the same plane, so that the labor of facing the
surfaces of the joints is reduced.
The Invention consists, thirdly, in constructing the upper part of the air
vessel with a moveable cover, whereby the delivery valves can be reached.
without removing or disconnecting the air vessel or the delivery pipes leading
therefrom.
And it consists, finally, in a compound valve of india-rubber and leather of
novel construction, whereby the advantages of both of those materials are
obtained without the disadvantages of either.
Figs. 1 and 2 in the accompanying Drawings are central vertical sections,
taken at right angles to each other, of a pump in which the several: improve-
ments are illustrated; Fig. 3 is a horizontal section of the cylinder, and a plan
of the inlet valve box with the bonnet removed; Fig. 4 is a plan of the
improved compound valve; and Fig. 5 is a section of the same:
A is the cylinder or barrel of the pump, cast with longitudinal passages D
and Fon opposite sides, with an offset F¹ at the upper part for the attach-
ment of the air vessel, H, and with a broad flat flange A' around the bottom,
by which it is bolted to the flat upper surface of the sole plate S. The flange
A also serves by the use of a single joint composed of two plane surfaces, as
a cover to the lower valve chamber S', which is cast in the sole plate. The
lower valve chamber is divided by a partition p, Fig. 3; into two compartments
cach of which contains one of the inlet valves c, d, and seats f, g, the openings
of the seats communicating with a passage h (Fig. 2), with which the suction
pipe s is connected. The compartment of the valve box which contains the

page_text: valve c communicates by a passage C with the lower part of the cylinder, and
the compartment-which contains the valve d communicates by the passage D
with the upper part of the cylinder. The cylinder is fitted with a piston B,
operated by a rod 6 passing through a stuffing box a in the cylinder head in
the ordinary manner. The flange A¹ is provided with an opening over the valve
chamber S¹, and this opening is fitted with a bonnet S" (Fig. 2) by the removal
of which both of the valves c and d may be reached. This passage F, which
leads from the lower part of the cylinder, and a passage G leading from the
upper part of the cylinder, communicate with the seats f¹, 9', of the delivery
valves c, d, which are placed in separate compartments of the upper valve
chamber T, Fig. 1, these compartments being separated by a partition t.
This valve chamber is formed in the lower part of the air vessel H, and a
guard bar I is formed in the same casting with the air vessel, to prevent the
valves from getting out of place. The valve seats f¹ and g¹ are formed in the
offset of the cylinder, which is faced flush or in the same plane with the
top of the cylinder. The air vessel H and the cylinder cover N, are faced to
fit this plane surface, which may be finished at one operation in a lathe with
very little labour. The delivery pipe P is attached to one side of the air
vessel. The air vessel is constructed or fitted with a moveable cover H', which
is screwed on or otherwise secured in place. By the removal of this cover,
the valves c and d¹ may be reached by inserting the hand through the opening
in the top of the air vessel. The suction pipes is connected with the
passage by means of an union joint w, and at this connection there is fitted
a valve U, which opens while the pump is in operation, but closes to prevent
the pump losing its water when at rest for any time. This valve is first
formed of a single piece of sheet india-rubber v, which also serves as a packing
ring to the joint, and there is cemented to it a ring, of leather w.
The valve
is loaded with a weight x, by which it is closed, the weight being secured by
a rivet y and metal washer to the india-rubber. The leather ring w slips
easily against one surface of the joint in screwing it up, and thus prevents the
joint from being loosened by the action of the india-rubber after it has been
screwed up, thereby producing all the advantage of an india-rubber and a
leather valve, without the disadvantages of either. A compound leather and
india-rubber valve of this kind may be advantageously used in all cases in
which a screwed or union joint is applied to hold a valve in place.
Having now described the Invention that has been communicated to me as
aforesaid, and having explained the manner in which the same 'is carried into
effect, I claim,-
1st, the arrangement of the chamber S¹ containing the inlet valves and

page_text: their seats in a double-acting pump, as herein described, in which the cover
of the chamber is formed of the flange of the cylinder, with the same joint
composed of two plane surfaces, and is used to secure the cylinder to the sole
plate S, so that the valves are enabled to be reached by the removal of a small
bonnet.
2nd, the arrangement of the delivery valves c', d', and their containing
chamber T, and seats in relation to the air vessel H and cylinder, as herein
described, whereby the connection of the passages of the cylinder with the air
vessel, and of the cylinder cover with the cylinder, are formed by joints in the
same plane.
3rd, providing the air vessel with a moveable lid or cover H¹, as and for
the purpose herein specified.
4th, the compound india-rubber and leather valve U constructed as and for
the purpose herein set forth.
In witness whereof, I, the said William Edward Newton, have hereunto
set my hand and seal, this Thirteenth day of April, in the year of
our Lord One thousand eight hundred and sixty-five.
Witness,
J. W. MOFFATT,
