We ROBERT ROYON BEARD of 90 Fort Road, Bermondsey, in the County of
Surrey, Engineer and WALTER HENRY OAKLEY of 202 Grange Road, Bermondsey
aforesaid Engineer do hereby declare the nature of our invention for "IMPROVE-.
MENTS IN AND CONNECTED WITH VALVES FOR CONTROLLING THE 'FLOW OF GAS,
WATER, AND OTHER FLUIDS," to be as follows:—
The object of our invention is to produce an automatic regulator for use with
all kinds of fluids but more particularly for use with compressed gas such as-
that employed with the oxyhydrogen light which requires a regulator of great
sensitiveness.
In carrying out our invention we employ a screw down valve of any convenient
construction which is actuated by the rising and falling of a diaphragm a piston,
a plunger, a float or equivalent contrivance under the influence of the fluid to be
regulated.
The valve stem or spindle is threaded with a slow and quick thread the greater
part with the quick thread.
On this portion the diaphragm or other contrivance is mounted and as the
pressure increases underneath this diaphragm is caused to rise on the thread and
rotate the stem thereby screwing down the valve and vice versa. means being
provided to prevent the turning of the diaphragm.
The slow threaded portion of the stem works in a threaded socket suitably
placed above the valve seat to receive it.
When a diaphragm is employed we prefer it shall form the top of a bellows. into
which the fluid enters.
The inlet and exit passages for the fluid may be arranged in any convenient
manner and the valve may be single double conical or other suitable shape the
essential feature of the invention being the means for actuating the valve that is to
say converting the rectilinear motion of the diaphragm or equivalent contrivance
caused by the increase or decrease of pressure into a rotary motion for the purpose
of closing or opening the valve.

We ROBERT ROYOU BEARD of 90 Fort Road, Bermondsey in the County of
Surrey, Engineer, and WALTER HENRY OAKLEY of 202 Grange Road, Bermondsey
aforesaid, Engineer do hereby declare the nature of our invention for IMPROVE-
MENTS IN AND CONNECTED WITH VALVES FOR CONTROLLING THE FLOW OF GAS,
WATER AND OTHER FLUIDS and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:-
The pressure regulator which forms the subject of this invention is designed to!
regulate the flow of all kinds of fluids, but the primary object we have in view is:
to obtain a sensitive regulator for use with the compressed gases employed for the
.production of the oxyhydrogen or oxycalcium light."
I
Our invention consists in a novel application of a quick and slow threaded screw
for working automatically the delivery valve for the fluid.
In the accompanying drawings, we have shown our invention as adapted for a
compressed gas regulator and for a steam regulator, also for controlling the flow of
water.
Fig. 1 shows in side elevation the form our invention takes for automatically
regulating the delivery, at a uniform pressure, of compressed gas. Fig. 2 is a
vertical section of the same, taken in the line 1, 2 of Fig. 1, and Fig. 3 is a
sectional plan taken in the line 3, 4 of Fig. 2.

A is a circular bellows formed of india rubber or other flexible material having a
base plate B to which it is attached, and a movable head C, which is weighted,
as desired, to maintain the requisite pressure upon the gas. The plate B of the
bellows is screwed to a casting D, which carries at its centre a valve seat d, and has
projecting from it laterally a delivery pipe di furnished with a cock d-d³ is a
screwed socket formed in the bottom of the casting, and intended to fit upon the
screwed neck with which the gas reservoir is fitted. Mounted on the base plate B
is a cylindrical case E, which is made fast by bayonet joints, or their equivalent, to
the plate, and is intended to serve as a protection to the bellows. The movable
bead C is fitted with a central tube c closed at its upper end, and contracted at its
lower end into a neck c', which is threaded internally to receive a quick screw F.
This screw forms the spindle of the regulating valve f, which fits the valve seat d
made in the casting D. Immediately above the valve, a slow thread f¹ is cut on
the valve spindle, and in a neck of the base plate B, a thread b is cut corresponding
with the thread f¹ on the valve spindle. Openings are made in this neck for the
passage upwards of the gas into the bellows, and as the pressures of the gas vary,
the bellows will be caused to expand or contract, the tendency of the weighted
head C being to force the bellows into the compressed stute. As the weighted head
descends, it will impart an axial motion to the valve spindle, and thereby cause the
valve, under the action of the screwed neck b, to recedo from its valve seat, and
thereby enlarge the opening for the delivery of the gas. When the pressure of the
gas is in excess, it will be necessary to contract the delivery opening. This is done
by the rise of the bellows head under the excessive pressure, which rise, by giving

page_text: an axial motion to the valve spindle in the opposite direction, forces down the
valve towards its seat. By this means an automatic regulation of the delivery is
effected, the weight of the head being adjusted to suit the requirements of the case.
The head of the bellows is fitted with a safety valve c², which will prevent the
rupture of the bellows, should the compressed gas in full force be admitted thereto.
Fig. 4 shows in side elevation, Fig. 5 in vertical section, and Fig. 6 in sectional
plan, our invention as adapted for the automatic regulation of the pressure of
steam, Fig. 5 being a section in the line 5, 6 of Fig. 4, and Fig. 6 a section in the
line 7, 8 of Fig. 5.
In this example we have shown a double poppet valve connected by its stem to
its spindle F, in such a way as to allow of the rotation of the spindle to lift or
depress the valve without imparting an axial motion to the valve itself. The valve
spindle is formed, like that before described, as a quick threaded screw for a
piston C to slide up and down, and is furnished also with a slow screw thread f¹,"
which works in a central tapped hole in the bottom B of a steam cylinder A.
The double valve f has its seats in the upper and lower sides of a central
chamber formed in a casting D, which is provided with a screwed neck d for fitting
on to the steam supply pipe, and has also a screwed neck d² for connecting with the
steam delivery pipe.
The steam is admitted to the central valve chamber, and passes out therefrom
by the double valve.f into a steam space surrounding the valve chamber, whence
it is free to pass out at the nozzle d.
Openings are made in the bottom B of the cylinder A, for admitting steam from
the steam space below to the underside of the piston C. The piston C is formed
with a tubular chamber c for receiving the screwed valve spindle. This chamber
is made sufficiently long to allow for the free play of the piston in the cylinder.
The connection of the spindle with its valve is made by screws, which pass
laterally through the valve stem, and enter an annular groove in the lower end
of the screwed spindle F as shown at Fig. 5.
Enclosing the steam cylinder and its piston is a cylindrical cover E, which is
grooved vertically to slide over fixed guides attached to the steam cylinder. This
cover is formed at its top, or closed end, with a squared socket to receive the
squared end of the tube c, for the purpose of arresting any tendency of the piston
to move axially. The lower edge of this cylindrical cover E is made with a
flange for receiving annular weights, by which the pressure of the steam is
balanced.
The action of this pressure regulator is as follows :—
As the steam enters this properly weighted pressure regulator, it will pass the
valve and fill the cylinder A, and eventually pass out at the neck . When
the pressure of the steam is in excess of that required, it will force up the piston
against the action of the counter-weights carried by the cover E, and thereby
cause the piston to impart an axial motion to the spindle F, and force the double
valve towards its seats,. thereby contracting the openings for the passage of the
steam. Should, however, the pressure of the steam diminish, the piston will fall
and cause the valve to present au increased area to the passage of the steam.
From the foregoing description it will be obvious that our pressure regulator
may be applied to regulate the flow of water, say into a tank or reservoir.
We have shown, at Figs. 7, 8, and 9, in elevation, vertical section, and plan view,
a modification of the last described pressure regulator suitable for this purpose.
In this example, the rising of the valve f serves to contract or close the openings
for the flow of the liquid, but the action of the regulator is precisely the same
as that just described. The water passes into the space surrounding valvo
chamber, and flows thence through openings made in a plate D' forming the
bottom of the casting D, to the tank or reservoir, over which the regulator is
fixed. Pendent from the double valve stem is the screwed spindle F, which
works in a threaded hole in the bottom plate D¹; and for imparting the axial
motion to this spindle, a float C is employed, which, like the piston of Fig. 5, is

page_text: formed with a threaded centre c', corresponding with the quick thread of the spindle.
This float is formed to receive two fixed guides c³ pendent from the bottom plate D',
and threaded on their inner ends to attach the plate to the casting D. By means
of these rods, the float is prevented from turning while making its vertical move-
ments. As the float rises and falls with the variations in the level of the water, it
will automatically regulate the position of the valve with regard to its seats, and
thereby control the admission of the supply. .
Having now particularly described and ascertained the nature of our said
Invention and in what manner the same is to be performed, we declare that what
we claim is
The means above described for automatically regulating the position of valves
employed in controlling the flow of gaseous and other fluids.
