I, ALFRED VINCENT NEWTON, of the Office for Patents, 66, Chancery
Lane, in the County of Middlesex, Mechanical Draughtsman, do
hereby declare the nature of the said Invention for "AN IMPROVEMENT IN
PUMPS," to be as follows:-
The general object of this Invention is to adapt steam and other
pumps to work in different positions without inverting or changing the
normal position of either the suction or delivery valves, or both, whereby

page_text: the action of the valve or valves is similar and equally perfect or easy in
different positions of the outer case of the pump, that may accordingly
be arranged to work horizontally, vertically, or at any intermediate
inclination. This will be found of great service in pumps used for
mining purposes, as when sinking shafts, either vertical or inclined, or
for working in a horizontal drift.
The Invention consists in a valve box fitted to turn on or around its
axis within the pump case or chamber thercof, and in an annular
excentric or other suitably shaped passage in said chamber or case and
around the valve box, whereby in all positions of the pump a free com-
munication is extablished with the under or inner side of the valve,
while its upper or opposite side is closed to such communication.
The Invention also consists in combination with such construction of
the valve box and its chamber of an index which may either be a rib or
mark on the outside of the valve box to show the position of the valve
from the outside within its turning valve box for the purpose of
facilitating the adjustment of the valve and valve box to different
positions of the pump.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Alfred Vincent Newton in the Great Seal Patent
Office on the 9th September 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALFRED
VINCENT NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Mechanical Draughtsman, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of March, in the year
of our Lord One thousand eight hundred and seventy-four, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said Alfred Vincent Newton, Her special
licence that I, the said Alfred Vincent Newton, my executors, admi-
nistrators, and assigns, or such others as I, the said Alfred Vincent
Newton, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times there.

after 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 Inven-
tion for "AN IMPROVEMENT IN PUMPS," being a communication to me from
abroad by William John Silver and George Attwood, both of Salt Lake
City, in the Territory of Utah, United States of America, upon the
condition (amongst others) that I, the said Alfred Vincent Newton,
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 Alfred Vincent Newton, 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, reference being had to the Drawing
hereunto annexed and to the letters and figures marked thereon (that is
to say):
The general object of this Invention is to adapt steam and other
pumps to work in different positions without inverting or changing the
normal position of either the suction or delivery valves, or both, whereby
the action of the valve or valves is similar and equally perfect or easy in
different positions of the outer case of the pump, which may accordingly
be arranged to work horizontally, vertically, or at any intermediate.
inclination. This will be found of great service in pumps used for
mining purposes, as when sinking shafts, either vertical or inclined, or
for working in a horizontal drift.
The Invention consists in a valve box fitted to turn on or around its
axis within the pump case or chamber thereof, and in an annular
excentric or other suitably shaped passage in said chamber or case and.
around the valve box, whereby in all positions of the pump a free com-
munication is established with-the under or inner side of the valve, while
its upper or opposite side is closed to such communication. On its out-
side the valve box is furnished with an index, which may either be a rib
or mark to show the position of the valve from the outside within its
turning valve box, and thereby to facilitate the adjustment of the valve
and valve box to different positions of the pump.

page_text: In the accompanying Drawing Fig. 1 represents a side view of a pump
case in part with valve box and valve constructed in accordance with the
Invention; Fig. 2 is a rear or end elevation of the same; Fig. 3 is a
section on the line x, x, of Fig. 1, and Fig. 4 is a section on the
line y, Y.
Fig. 5 represents a sectional view of a pump in part under a different
arrangement of the passages, and with hinged or flat valves substituted
for puppet ones, but showing the same general principles or features of
the Invention as illustrated in the other Figures. Similar letters of
reference indicate corresponding parts.
"
Referring in the first instance to Figures 1, 2, 3, and 4 of the
Drawing, A is the valve box, case, or chamber of a pump having an inlet,
or suction passage B and outlet C arranged at right angles thereto. The
case A is constructed with circular bearings b, b, to receive within them
from the outside a cylindrical valve box D made to form a close but free
fit with said bearings, but leaving an annular or excentric chamber E all.
around the body of the valve box between its bearings 6, b, to establish
free communication in all changed positions of the pump with the under
or inner side of the valve G, which is arranged to open and close a
lateral opening d in the body of the valve box; said valve opening
upwards or outwards and more or less within a chamber e in the valve
box. This chamber e is open at the back or inner end of the valve box
so as to be in free communication at all times with the outlet C. A
clamp or cross bar H applied to the back or outer end of the valve box
and secured by screws f,f, serves to keep the latter in place.
Any kind of valve including round rubber ones may be used in con-
nection with the Invention.
:
It will be evident that by turning the valve box on or around its axis,
the valve may always be made, to preserve its normal position in all
changed positions of the pump case from the two extremes of a horizontal
to a vertical position or any intermediate one. To facilitate this, adjust-
ment and to indicate the position of the valve when changing the position
of the pump case, the valve box D is provided on its outside with an
index I which may either be a rib or raised mark or a depression, but
which serves to indicate the direction of the valve's action or the position
of the valve.
In Fig. 5 of the Drawing, A is the valve box case portion of a 'pump,

page_text: B its inlet or suction passage, and C its outlet or delivery passage;
D, D, are the valve boxes of the inlet and outlet passages, both being of
a cylindrical construction to provide for the turning of them on or
around their axes, substantially as and for the purposes herein-before
set forth. The valve boxes are however provided with hinged or flap
valves G, G, in the place of puppet valves shown in the first described
arrangement; E, E, are the annular or excentric chambers around the
bodies of the valve boxes between the bearings b, b; and d, d, are the
lateral openings in the valve boxes in communication with the annular
or excentric chambers; e, e, are the chambers into which the valves
G, G, open upwards or outwards, and more or less within; S is the
plunger of the pump. The valve boxes may be kept in place by means
of a clamp or cross bar H and screws f, f, as in the first described
arrangement, also an index I be applied to the exterior of the valve
boxes to indicate the position of the valves.
Having now set forth the nature of the Invention of "An Improve-
ment in Pumps," as communicated to me by my foreign correspondents,
and explained the manner of carrying the same into effect, I wish it be
understood that under the above in part recited Letters Patent,
I claim,―
First. The valve box made capable of adjustment on or around its
axis within its case or chamber, and fitted with a valve for operation in
relation with a side aperture and end passage in the valve box, whereby
the valve may be made to retain its normal position in various or
changed positions of the pump case, substantially as specified.
Second. The combination with the axially adjustable or turning valve
box D of the passage E in the case A arranged to surround said box,
essentially as and for the purpose herein set forth.
In witness whereof, I, the said Alfred Vincent Newton, have here-
unto set my hand and seal, the Fourth day of September, in the
year of our Lord One thousand eight hundred and seventy-four.
