Year: 1870

page_text: LETTERS PATENT to Edmund William Pyle Taunton, of Birmingham,,
in the County of Warwick, Manufacturer, for the Invention of
"IMPROVEMENTS IN PUMPS FOR RAISING AND FORCING LIQUIDS."-A com-.
munication from abroad by George C. Bishop, of the City of
Montreal, Canada.
PROVISIONAL SPECIFICATION left by the said Edmund William Pyle
Taunton at the Office of the Commissioners of Patents, with his.
Petition, on the 11th August 1870.
I, EDMUND WILLIAM PYLE TAUNTON, of Birmingham, in the County
of Warwick, Manufacturer, do hereby declare the nature of the said.
Invention for "IMPROVEMENTS IN PUMPS FOR RAISING AND FORCING LIQUIDS,"
to be as follows:-
The said Invention consists in constructing and arranging the parts
of pumps for raising and forcing liquids in the manner herein-after
described.

page_text: The body of the pump consists of a hollow cylinder situated horizontally.
In the axis of the said cylinder is a shaft carrying a plate, which plate
extends from the said shaft to the ends and inner cylindrical surface of
the said hollow cylinder, and constitutes a piston capable of being made
to oscillate by the shaft; the ends of the shaft pass through the ends of
the cylinder, and by means of a handle or handles an oscillating motion
can be given to the said shaft and piston. The said oscillating piston is
provided with a valve on each side of the shaft, the said valves being
hinged to the said piston and opening upwards. On the upper side of
the pump cylinder is the egress or delivery pipe, and on the under side of
the said cylinder is the ingress or suction pipe. Within the cylinder and
immediately over the suction pipe is a fixed partition, the said partition
having the figure of an inverted letter V. By means of the said partition
communication between the suction pipe and the delivery pipe is cut off,
excepting through valves, one on each of the sides of the said V-shaped
partition. These valves open upwards; the said partition extends from
end to end of the pump cylinder, and the shaft of the oscillating piston
works closely upon a concave bed on the top of the said partition. By
giving an oscillating motion to the piston by means of the handle and
shaft the valve on the descending side of the piston opens, while that on
the ascending side closes, the reverse taking place with respect to the
valves in the V-shaped partition, that is to say, the ascending side of the
piston with its closed valve produces an exhaustion between itself and
the side of the V-shaped partition, over which it works, and water rising
through the suction pipe passes through the valve in the partition and
fills the enlarging space between the partition and the ascending side of
the piston, the liquid above the ascending piston being forced out of the
delivery pipe at the top of the cylinder. As the other side of the piston
descends the valve in the partition under it closes, and the valve in the
said descending side opens, letting the water pass from below to the
upper side of the said piston; the actions described take place at each
stroke of the piston. An ordinary conical valve may be situated in the
delivery pipe, which valve may be protected by a cover to prevent any
obstructing matter falling on the valve.

within six calendar months next and immediately after the date of the
said Letters Patent.
B
NOW KNOW YE, that I, the said Edmund William Pyle Taunton, 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 :—
The said Invention consists in constructing and arranging the parts
of pumps for raising and forcing liquids in the manner herein-after
Josanibod

page_text: The body of the pump consists of a hollow cylinder situated horizontally.
In the axis of the said cylinder is a shaft carrying a plate, which plate
extends from the said shaft to the ends and inner cylindrical surface of
the said hollow cylinder, and constitutes a piston capable of being made
to oscillate by the shaft. The ends of the shaft pass through the ends of
the cylinder, and by means of a handle or handles an oscillating motion
can be given to the said shaft and piston. The said oscillating piston is
provided with a valve on each side of the shaft, the said valves being
hinged to the said piston, and opening upwards. On the upper side of
the pump cylinder is the egress or delivery pipe, and on the under side
of the said cylinder is the ingress or suction pipe. Within the cylinder
`and immediately over the suction pipe is a fixed partition, the said
partition having the figure of an inverted letter V. By means of the
said partition communication between the suction pipe and the delivery
pipe is cut off excepting through valves one on each of the sides of the
said V-shaped partition. These valves open upwards. The said partition
extends from end to end of the pump cylinder, and the shaft of the
oscillating piston works closely upon a concave bed on the top of the
said partition. By giving an oscillating motion to the piston by means
of the handle and shaft the valve on the descending side of the piston
opens, while that on the ascending side closes, the reverse taking place
with respect to the valves in the V-shaped partition, that is to say, the
ascending side of the piston with its closed valve produces an exhaustion
between itself and the side of the V-shaped partition over which it works,
and water rising through the suction pipe passes through the valve in
the partition and fills the enlarging space between the partition and the
ascending side of the piston, the liquid above the ascending piston being
forced out of the delivery pipe at the top of the cylinder. As the other
side of the piston descends the valve in the partition under it closes, and
the valve in the said descending side opens, letting the water pass from
below to the upper side of the said piston. The actions described take
place at each stroke of the piston. An ordinary conical valve may be
situated in the delivery pipe, which valve may be protected by a cover
to prevent any obstructing matter falling on the valve.
Having explained the nature of the said Invention, I will proceed to
describe with reference to the accompanying Drawings the manner in
which the same is to be performed.
Figure 1 represents in side elevation, and Figure 2 in transverse

page_text: vertical section a hand pump for raising and forcing liquids constructed
according to this Invention; Figure 3 is a plan of the oscillating piston
of the pump detached. The same letters of reference indicate the same
parts in each of the Figures of the Drawings.
a is the body of the pump, consisting of a hollow cylinder situated
horizontally and closed at its ends by the flanged discs a², a²; bis
the oscillating piston, situated in the cylindrical body a, and crossing
the axis of the said body in the direction of a diameter, the said
piston being carried by the shaft c. The said oscillating piston 6 consists
of a plate extending on either side the shaft c to the cylindrical surface
of the hollow cylindrical body a, and also to the ends of the said
body. The piston 6 is provided with hinged valves 62, 63, one on either
side the shaft c, the said valves opening upwards. The ends of the
piston shaft c pass through the ends a², a², of the cylindrical body a,
and work in bearings or journals at a³, a³, in the said ends a², a². The
ends of the piston shaft b`may work through stuffing boxes. The
extreme ends of the piston shaft b outside the body a are connected
together by the bail handle d, by means of which handle an oscillating
motion can be given to the shaft c and piston b. e is the egress or
delivery pipe at the top of the cylindrical body a, and fis the ingress
or suction pipe at the under side of the said body a; g is the fixed
inverted V-shaped partition within the cylindrical body a and imme-
diately over the suction pipe f, the said fixed partition extending from
end to end of the body a. The shaft c of the piston 6 seats itself closely
upon the top of the partition g, which partition is provided with a
packing to-make a close joint between it and the shaft c. On each side
of the partition g is a hinged valve marked respectively g², g³, opening
upwards. By means of the partition g communication between the
suction pipe f and delivery pipe e is cut off, excepting through the
valves g, g. In the discharge pipe e is a suspended conical plug valve h,
the upper rim or shoulder of the said plug valve resting on the seat i.
Above the discharge pipe e is a reservoir k having a spout 7 on one side.
The reservoir / is covered by a cap k², by means of which any obstructing
matter is prevented from falling on the plug valve h. The use of the
plug valve h in the discharge pipe e is to keep the space between the
oscillating piston 6 and valve plug / charged with liquid, whereby the
pump is always ready for work. By raising or removing the plug valve h
the liquid in the body of the pump will slowly descend into the suction
h

page_text: pipe, and thus prevent the pump being rendered useless in frosty weather.
The valve plug h may be dispensed with. The person working the
pump stands at the side A, Figure 2, and by moving the bail handle d
to and fro an oscillating motion is given to the piston b and shaft c.
In Figure 2 the oscillating piston 6 is represented at the middle of its
stroke, and is indicated in dotted lines at the end of its stroke in one
direction. When the piston b is moved through a portion of a circle, as
indicated in dotted lines, the valve 63 on its descending side opens, while
the valve 62 on its ascending side closes, the reverse taking place with
respect to the valves 92, 93, of the fixed partition g. As the ascending
side of the piston 6 with its closed valve rises an exhaustion is produced
between the ascending side of the piston and that side of the partition g
over which it works, and water rising through the suction pipe ƒ passes
through the open valve 92, and fills the enlarging space between the
partition g and the ascending side of the piston b, the liquid above the
piston being forced out at the delivery pipe e, first raising the plug
valve into the reservoir k, and from thence it escapes by the spout 7.
As the descending side of the piston 6 approaches the partition g the
valve g³ in the said partition closes, and the water between the said
partition and the descending side of the piston forces open the valve ³,
and passes from below to the upper side of the piston. On the piston
making its return stroke the same actions take place, but on opposite
sides of the piston, water being forced out of the cylinder a by the
ascending side of the piston, while a fresh supply is drawn from
the suction pipe into the space between the said ascending side of the
piston and the partition, at the same time the descending side of the
piston forces the water from its under to its upper side. In this way a
continuous or nearly continuous stream of water is raised and delivered
by the action of the pump. The pump may be worked by hand or by
steam or other power. In the latter case a connecting rod or lever
worked by the steam or other power is affixed to one end of the shaft of
the oscillating piston b.
Figure 4 represents in front elevation, Figure 5 in side elevation;
Figure 6 in transverse vertical section, and Figure 7 in plan, a modi-
fication of the pump herein-before described; Figure 8 represents the
handle detached by which the oscillating piston is worked.
The action of this pump is the same as that first described, and corre-
sponding parts are marked with the same letters of reference. The

page_text: principal parts or details in respect of which this pump differs from that
first described, are as follows:-
The cylindrical body a is open at top and expands into a reservoir k,
the delivery pipe and its valve plug being omitted, the water raised and
forced by the pump being delivered directly into the said reservoir k
from whence it escapes by the spout 7. The ends a² and body a are
made in one piece. The lower part of the body a is made separate from
the upper part, the said lower part supporting the fixed partition g, g², g³,
The shaft c of the oscillating piston b, 62, 63, is secured to the body by
screw nuts outside the ends of the said body, the middle of the piston
within the body being provided with a tubular socket & to receive the
end of the handle d, by which an oscillating motion is given to the said
piston to work the pump. The fixed partition g over the suction pipe f
is nearly horizontal instead of an inverted V shape, the seats for the
valves g², g³, of the said partition being made in one piece with the
separate lower part of the body a of the pump (see Figure 6). The
valves, ³, of the oscillating piston 6 and the valves 92, 93, of the
partition g are in this arrangement made of leather and weighted, the
said leather valves being secured to the piston and partition respectively
by screw pins and bolts and nuts, as represented. The construction of
the packing at the working edges of the piston 6 and at its seat on the
fixed partition g for ensuring a tight joint between the said parts will be
understood by an examination of the section Figure 6.
By arranging the parts of the pump in the manner represented in
Figures 4, 5, 6, and 7, great facility is afforded for gaining access to the
valves, the removal of the separate lower part of the body detaching the
whole of the valvular partition from the pump, and the withdrawal of
the shaft permitting of the removal of the piston through the open top
of the body of the pump.
This modification of the pump may be worked by steam or other
power instead of by hand.
Having now described the nature of the said Invention, and the
manner in which the same is to be performed, I wish it to be understood
that I do not limit myself to the precise details herein described and
illustrated, as the same may be varied without departing from the
nature of the said Invention; but I claim as the said Invention of
improvements in pumps for raising and forcing liquids,-

page_text: Firstly. The combination or arrangement of the hollow cylindrical
body a, oscillating valvular piston b, 62, 63, working in the said body, and
the fixed valvular partition 9, 9², g³, the said parts being constructed and
the oscillating piston worked substantially as herein-before described and
illustrated in the accompanying Drawings.
Secondly. The combination with the said cylindrical body, piston, and
partition of the outlet pipe e, and valve plug h, and parts connected
therewith for the purpose and substantially as herein-before described
and illustrated in the accompanying Drawings.
In witness whereof, I, the said. Edmund William Pyle Taunton,
have hereunto set my hand and seal, this Second day of February,
in the year of our Lord One thousand eight hundred and
seventy-one.
