IMPROVEMENTS IN PUMPS." A communication from abroad by Albert
PROVISIONAL SPECIFICATION left by the said Henry Edward Newton at
the Office of the Commissioners of Patents on the 30th July 1880.
HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer. "IMPROVEMENTS IN PUMPS." [A communi-
cation from abroad by Albert Louis George Dehne, of Halle on the Saal, in the
Empire of Germany.]
These improvements refer to the construction and arrangements of the valves
and valve casings, the centre line of the valve casing lying horizontally, and in
which casing the suction or pressure valve is arranged, the casing forming at the
same time the seat for the valve. The valve may either be a clack valve, or ball
valve, or disc valve, and may be made of any suitable material, and the valve may
work within the casing with or without the employment of spring pressure.
The valve seat on which the valve rests is formed in the valve casing. To
introduce the valve the upper part of the casing is made removable, and is capable
of being secured by a screw thread to the casing; this part forms at the same time
the guide for the valve rod.
In adapting these valves to a pump cylinder, separate valve chambers are
arranged and preferably cast in one piece with the cylinder, one for each horizontal
valve casing. Into these chambers the casings containing the valves may easily
be introduced or withdrawn. Two valve chambers are arranged on each side of
the cylinder, and all four chambers are arranged in one plane parallel to the
ground line or foot of the cylinder. The two chambers on the same side of the
cylinder are connected together, and through them on the one side the entrance,
and on the other side the exit of the pumped liquid takes place.
The four valve chambers are all of equal or identical form, so that the casings
with their valves may be inserted at will on either side of the cylinder, and by
such changing the suction pipe may be converted into the delivery pipe, and
vice versa.
Single acting pumps may be provided with valve chambers at one end of the
cylinder only.

the said Henry Edward Newton in the Great Seal Patent Office on the
27th January 1881.
HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer. "IMPROVEMENTS IN PUMPS." A communi-
cation from abroad by Albert Louis George Dehne, of Halle on the Saal, in the
Empire of Germany.
These improvements refer to the construction and arrangement of the valve
casings in which the suction and delivery valves are placed, the casing forming the
seat for the valve and having its centre line horizontal. The valve may either
be a clack, ball, or disc valve, and may work within the casing with or without the
employment of spring pressure.
In the accompanying Drawing, Fig. 1 is a plan of the valve casing containing a
suction valve of the disc order; Fig. 2 is a cross section of the same on the line
A, B, of Fig. 1; Fig. 3 is a vertical section taken on the line C, D, of Fig. 1 and at
right angles to Fig. 2; Fig. 4 is a plan partly in section on the line E, F, of Fig. 3.
In Fig. 4 the valve is omitted; Fig. 5 is a plan of a valve casing containing a
delivery valve also of the disc order; Fig. 6 is a cross section of the same on the
line A, B, of Fig. 5; Fig. 7 is a vertical section through the line C, D, of Fig. 5;
Fig. 8 is a plan in section through the line E, F, of Fig. 7.
In Fig. 8 the valve itself is omitted.
The valve casing a, which is cylindrical, is formed with a valve seat b on which
the valve crests. In order to introduce the valve c into its casing the upper
part d of the casing is made removable, and is capable of being secured by a screw
thread to the casing. This part d is formed with a cap or socket which acts as a
guide for the valve rod e.
In the suction valve casing the liquid is drawn in through the bottom of the
casing, and it enters the cylinder through the opening fin the wall of the casing in
the direction of the arrows.
In the delivery valve casing the bottom of the casing is closed so as to form a
chamber a¹ below the valve, the liquid entering this chamber through the side
opening a², Fig. 7. The liquid in passing from this chamber a¹ raises the valve c
and escapes through openings formed in the upper part d of the casings, see
Fig. 7, as well as through openings a³, a³, in the walls of the casing, see Fig. 6,
into the delivery passage B.
All the valve casings are made of the same dimensions externally so that they
may be interchanged if desired; Fig. 9 is a side view of a pump cylinder arranged
with four valve casings and valves; Fig. 10 is a cross section of the pump cylinder
taken on the line G, H, of Fig. 9; Fig. 11 is a sectional plan taken through the
centre of the pump cylinder.
In adapting these valve casings to the cylinder of a pump, the cylinder is cast
or formed with a valve chamber for each horizontal valve casing, and into these
valve chambers the casings with the valves are introduced. Two valve chambers
are arranged on either side of the cylinder, and all four chambers are arranged in
one plane parallel to the ground line or foot of the cylinder. The two chambers
on the same side of the cylinder are connected together by a passage, and through
these passages the entrance and the exit of the pumped liquid take place.
The four valve chambers are identical in form and dimensions, so that the position
of the suction and delivery valves with their casings may be transposed if desired,
by which means the suction pipe may be converted into the delivery pipe, and
vice versa.
In Figures 9, 10, and 11, a, a, are the suction valves, and b, b, the delivery

page_text: valves; A and B are the passages connecting respectively the two suction valves
a, a, and the two delivery valves b, b, with the supply and delivery pipes A¹, B¹.
c, c, is a jacket or casing serving for cooling or heating purposes, as for instance,
when used with air compressing or blasting engines; d is the foot of the cylinder.
Single acting pumps may be provided with valve chambers at one end of the
cylinder only. The valve chambers are provided with openings in their sides
through which the valve casings are inserted, and these openings are closed by
covers d which are held in place by crossheads e and screws f³.
Having now set forth the nature of this Invention for " Improvements in Pumps"
as communicated to me by my foreign correspondent, and explained the manner of
carrying the same into effect, I wish it to be understood that under the above in
part recited Letters Patent I claim,—
First. Constructing a valve casing to be fitted with a clack, ball, or disc valve
and capable of being inserted into or removed from a pump cylinder, and offering
at the same time a seat for the valve, substantially as herein shown and described.
Second. Arranging two valve chambers of equal form and dimensions and
connected together by suitable passages on both sides of a pump cylinder in a
plane parallel to the ground line of the said cylinder, such chambers being intended
for the reception of the above described valve casings with valves, substantially as
herein shown and described.
Third. The arrangement of the valve chambers for the reception of the valve
casings, substantially as herein shewn and described, so that by changing the valve
casings the supply pipe may be converted into the delivery pipe, and vice versa.
In witness whereof, I, the said Henry Edward Newton, have hereunto set
my hand and seal, the Twenty seventh day of January, in the year of our
Lord One thousand eight hundred and eighty one.
