IN VALVES FOR REGULATING THE FLOW AND PRESSURE OF LIQUIDS AND FLUIDS."
In applying our Improvements to push valves we forin the body in any
convenient shape. The piston valve which closes the inlet passage for the water,
is made of considerably larger diameter at the opposite or upper end and fitted
with a cup leather which fits and fills the body of the valve; a small hole is made
through the piston valve which allows the water a free passage into the chamber
or space between the upper part of the piston valve and the valve cover.
The push spindle for operating the valve slides in the valve cover and is fitted
with a cup leather near the head to prevent leakage to the lower end of this
spindle secured a leather rubber or other disc which has a seating on the lower
part of the cover and there is also a metal plug on the spindle below the leather
disc which when the valve is pushed and opened, fills or nearly fills a recess in the
upper part of the piston valve: a small passage is made from the chamber in the
valve cover and above the piston or push valve which leads into the outlet passage
for the water.
The operation is as follows:-When the valve is closed, water fills the chamber
above the piston valve and below the valve on the spindle to which it is at all
times free to enter by the small hole through the piston valve. The piston valve
is kept closed by the area on the upper side of the piston being considerably
greater than that of the inlet pipo.

page_text: When the spindle is pushed to open the valve, the water contained in the
chamber between the two valves passes under the spindlo valve into the space in
the valve cover and from it through the small passage into the discharge pipe and
the pressure of the water in the inlet pipe raises the piston valve and allows the
water to pass freely into the discharge pipe until the pusher piston is released when
the pressure of water in the chamber will raise the spindle valve and close it and
the piston valve will be brought on to its seating and closed automatically.
With a slight modification the above valve may be applied to steam, gas and
other fluids and liquids.
The inlet valve may be flat faced or V or wedge shaped. .
In applying our improvements to a pressure reducing valve, for water, we employ
a piston valve to close the inlet pipe; the opposite end of the piston is fitted with
a cup leather which fills a chamber of considerably larger diameter than the inlet
pipe a small hole is made through the piston valve and allows water to pass into
the chamber and another small hole conducts water from the chamber above the
piston and cup leather into the discharge pipe this passage is covered by a valvo
connected to a weighted spindle which has one or two pistons that slide in cylinders
made with the valve body and are provided with cup leathers—the pressure of
water in the discharge pipo acts upon these pistons. When more than one piston
is used we prefer to make them of different diameters in order to reduce the
weights on the spindle.
The operation is as follows:-When the inlet valve is open it admits water into
the outlet pipe until an increase of pressure takes place which will be felt on both
sides of the inlet valve and raise the piston fixed upon the weighted spindle and
the valve connected to it which closes or partially closes the small opening from
the chamber above the piston valve: this has the effect of increasing the pressure
in the chamber by the water which passes through the small opening in the valve.
The pressure acting on the upper and larger diameter of the piston closes or
partially closes the inlet valve until the fixed pressure is regained. It may be
necessary to regulate the size of the opening from the chamber to the discharge
pipe.
This reducing valve may, with slight modifications, bo applied to steam, gas or
other fluids and liquids.
The body of the valves may be made of metal, porcelain or other material.

LAWSON, Manager, both of Salford, in the County of Lancaster. "IMPROVEMENTS
IN VALVES FOR REGULATING THE FLOW AND PRESSURE OF LIQUIDS AND FLUIDS
"
Our invention relates to valves for regulating the flow and pressure of liquids
and fluids and our Improvements are illustrated by the accompanying Sheet of
drawings, in which
Fig. 1 is a sectional elevation of a push valve suitable for lavatories. Fig. 2
shows a valve for flushing pipes for urinals and other purposes. Fig. 3 represents
a sluice valve. Fig. 4 shows part of a sluice valve. Fig. 5 represents a valve for
a hydrant and Fig. 6 shows a pressure reducing valve to which our Improvements
are applied.
Similar letters refer to similar parts throughout the several views.
In applying our Invention to push valves we form the body in any convenient
shape.
On Fig. 1-a is the valve which closes the inlet passage b for the water:
connected to the valve a by a stem c is a piston d of considerably larger diameter
than the valve a and fitted with a cup leather which fits and fills the body of the
valve: a small hole e is made through the stom c which allows the water a free
passage into the chamber or space between the piston and the valve cover:
y are stops to regulate the lift of the valve. The push spindle h for operating
the valve slides in the valve cover and is fitted with a cup leather near the head
to prevent leakage: to the lower end of this spindle is secured a leather, rubber,
or other disc j which has a seating on the lower part of the cover and there is also
a metal plug on the spindle below the leather disc j which when the spindle h is
pushed, fills or nearly fills a recess in the upper part of the piston d: a small
passage is made from the chamber in the valve cover and above the piston or
push valve which leads into the outlet passage m for the water.
The operation is as follows:-When the valve is closed water fills the chamber j
above the piston d and below the valve on the spindle h, to which it is at all times
frée to enter by the small hole e through the valve stem c. The valve a is kept
closed by the pressure of water as the area on the upper side of the piston & is
considerably greater than that of the inlet b. When the spindle h is pushed to
open the valve, the water contained in the chamber passes around the spindle
valve into the space in the upper part of the valve cover and from it through the
sinall passage into the discharge pipe m, removing the pressure froin the upper
side of the piston d: the pressure of water in the inlet pipe braises the piston and
valve a and allows the water to pass freely into the discharge pipe m until the
pusher piston his released when the pressure of water in the chamber f will raise
the push valvej and close it and by the pressure on the piston d the valve a will
be brought down on to its seating and closed automatically.
The aperture n leading into the discharge pipe m must be smaller than the
inlet b to ensure the pressure needed to raise the push valve j.
With a slight modification the above valve may be applied to steam, gas, and
other fluids and liquids.
The inlet valve a may be fat faced or V or wedge shaped

page_text: Fig. 2 shows a valve having working parts similar to the valve shown on Fig 1
and operated in the same manner.
Fig. 3 represents a sluice valve to which our Improvements are applied.
We employ a weighted lever h¹ to raise and depress the push spindle h: the
water entering through the inlet b passes through the passage e in the stem c into
the space and by its pressure on the piston d keeps the slide valve o (connected
to the lower part of the stem c) closed. When the spindle h depressed the
water in the chamber ƒ flows through the passage into the outlet m and the
pressure under the piston a' raises the stein c opens the valve o and allows the
water to escape through the outlet m.
Fig. 4 shows part of a sluice valve through the cover of which we pass an
adjustable screwed rod 2 to regulate the lift of the valve: in this case we place the
push spindle h between the centre and the side of the valve cover.
Fig. 5 shows our Invention applied to a valve for a hydrant.
We employ a weighted lever h¹ to raise and depress the push spindle h. The
operation of the valve is similar to that of the valves shown on Figs. 1 and 2.
In applying our Improvements to a pressure reducing valvo for water we
employ a valve a to close the inlet b: the piston d on the stem c is fitted with a
cup leather which fills a chamber of considerably larger diameter than the inlet b:
a small hole e is made through the valve stem c which allows water to pass into
the chamber and another small hole or passage conducts water from the
chamber fabove the piston d into the discharge pipe m; this passage is closed by
a valve r connected to a weighted spindle s which has one or two pistons & t¹ that
slide in cylinders made with the valve body and are provided with cup leathers.-
the pressure of water in the discharge pipe m acts upon these pistons.-When
more than one piston is used we prefer to make them of different diameters as
shown so that we may reduce the weight on the lever which acts on the
spindles and push spindle h.
The operation is as follows:-When the inlet valve a is open it admits water
into the outlet pipe m until an increase of pressure takes place on the outlet m
which will be felt on both sides of the valve a and raise the pistons t t fixed upon
the weighted spindle s and the valve ? connected to it which will close or partially
close the small opening or passage from the chamber above the piston d. this
has the effect of increasing the pressure in the chamber by the water which passes
through the small opening e in the valve stem c: the pressure acting on the
piston d closes or partially closes the inlet valve a until the desired pressure is
regained. When the spindle is depressed by the lever v the plug / enters the
recess in the piston d, stops the flow of water through the passage e and accelerates
the opening of the valve a. It may be necessary to vary the size of the opening
from the clamber f to the discharge pipe m.
This reducing valve may with slight modifications be applied to steam gas or
other fluids and liquids.
The body of the valves may be made of metal, porcelain or other material.
Having stated the nature of our Invention and described the manner of
performing the same
We declare that we clai
1. The improved valves herein described and illustrated by Figs. 1, 2, 3, 4, and 5.
2. The improved valve having an inlet valve a and piston d connected by a stem c
provided with a passage e through which water or other fluid flows and closes by
its pressure on the piston d the valve a, in combination with the push spindle h
provided with a valve j and plug k, which plug is pushed into a recess in the
piston d to close the passage e and remove the pressure of the water or other fluid
(which escapes through the passage !) from the piston d and allow the valve a to
open as herein set forth.

3. An automatic pressure reducing valve having a valve a and piston & with
perforated stem c and the upper part of the valve chamber communicating with

page_text: the outlet m by a passage combined with the valve i piston or pistons t¹ and

substantially as herein described and as shown on Fig. 6.
In witness whereof I the said William Lawson for myself and on behalf of the
said William Henry Bailey have hereunto set my hand and seal this twenty eighth
day of March One thousand eight hundred and eighty four.
