Improvements in Pressure-regulating Valves for Highly Compressed
Gases and in Valves for Steam or Water Pressure.
We, DAN RYLANDS of Shepcote, Stairfoot, near Barnsley, in the County of
York, Glass Bottle Manufacturer, and CHARLES EMMET, of No. 194, Doncaster
Road, Barnsley aforesaid Mechanical Engineer, do hereby declare the nature of
this invention to be as follows:
Our invention relates to improvements in valves intended to resist very heavy
gaseous or liquid pressures, which valves when used in conjunction with iron or steel
bottles or cylinders are very suitable for the bottling and safe keeping of carbonic
acid, oxygen, hydrogen, or other compressed gases.
In carrying out our invention we provide a circular hollow bottomed valve
case of gun metal or other suitable metal, and we form externally on this valve
case a screw thread capable of engaging with a female screw thread carried by
the mouth of the iron or steel bottle. In the bottom of the valve case we insert
and secure by sweating or soldering a disc of soft copper, white metal, or other soft
and yielding metal constituting the seat of the valve. The upper internal diameter
of the valve case is screw-threaded for the reception of an externally-threaded
gland nut; and this gland nut is formed with an internal central screw thread, in
which internal thread a screw-down valve of steel, delta metal, or other suitable
metal, is free to work. The working end or face of this screw-down valve is
formed with any suitable number of concentric V shaped projections or annular
cutting edges.
Above the upper surface of the copper or white metal valve seat and the under
surface of the gland, and surrounding the unthreaded portion of the valve spindle, we
place a hydraulic leather of the usual construction; or in cases where a very heavy
pressure has to be withstood we use a packing ring of leather, woodite, or other
suitable packing material, this packing ring being externally of conical form, and for
the reception of this packing ring we provide a seating also of conical form in the
interior of the valve casing. In the centre of the soft metal valve seat, a small port
is provided communicating with the interior of the bottle. On the centre line of the
screw-down valve, a port is also formed or drilled extending from the upper end to
nearly the working face of the spindle, a port at right angles to the central port com-
municating with it. The upper end of the valve spindle is screw-threaded enabling
the valve spindle and with it the valve casing to be very readily connected by
means of a union joint or other form of connector with the gas-compressing pump
in the charging of the bottle, or with the discharge pipe connecting the bottle with
the receiver or container to be charged during the emptying of the bottle.
The hydraulic packing ring and gland nut being placed in position in the interior
of valve casing, the threaded valve spindle on being rotated will enter the central
threaded hole formed in the centre of the gland nut, further rotation of the spindle
will cause the concentric V shaped cutting faces or annular projections to come into
contact with the soft metal valve seating, and in doing so the harder metal of which
the valve spindle is composed will cut into and indent the soft metal constituting
the valve seating, and so make effectual joint and close and protect the contents
of the bottle.
To liberate the contents, the valve spindle is rotated in the opposite direction to
that previously described, when the valve face leaving the valve seating will allow
the contents to pass through the small port contained in the soft metal seating

page_text: into the space above the valve seating from, whence they are conveyed by the small
ports formed in the body of the valve into the previously-described discharge pipe.
It will be seen that the formation of valve face and the harder metal of which it
is composed will ensure a true and accurate joint with the softer and more yielding
metal of the valve seating, also that the valve forms or produces its own seating,
and that this seating must be a true seating, and will not deteriorate by wear.
Any suitable form of connector may be employed to connect the valve with the
charging or discharging pipes; but we prefer to use a connector provided with a
valve and seating of similar construction to that previously described.
We have described this invention in its application to the bottling, retention, and
liberation, of gases under very high tension; but it will be evident that our
.invention is applicable as a stop and release valve for steam or water pressure.

COMPLETE SPECIFICATION.
Improvements in Pressure-regulating Valves for Highly Compressed
Gases and in Valves for Steam or Water Pressure.
We DAN RYLANDS of Shepcote Stairfoot near Barnsley in the County of
York, Glass Bottle Manufacturer and CHARLES EMMET of No. 194, Doncaster
Road Barnsley aforesaid Mechanical Engineer, do hereby declare the nature of this
invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our invention relates to improvements in valves intended to resist very heavy
gaseous or liquid pressures, which valves when used in conjunction with iron or
steel bottles or cylinders are very suitable for the bottling and safe keeping of
carbonic acid, oxygen, hydrogen, or other compressed gases.
To illustrate our invention we append hereto two sheets of drawings in which
Figs. 1 and 2 are sectional elevations showing a valve in the closed and opened
positions respectively.
Fig. 3 is an elevation of the valve with the connector we prefer to use when
discharging the contents of the bottle and
Fig. 4 a view showing a valve in elevation, and in sectional elevation a
connector well adapted for coupling up the gas compressing pumps to the bottle to
be charged.
In carrying out our invention we provide a circular hollow bottomed valve case
(Figs. 1 2 and 3) of gun metal or other suitable metal, and we form externally on
this valve case a screw thread & capable of engaging with a female screw thread
carried by the mouth of the iron or steel bottle. In the bottom of the valve case
we insert and secure by sweating or soldering a disc c of soft copper, white metal,
or other soft and yielding metal constituting the seat of the valve.
The upper internal diameter d of the valve case is screw-threaded for the recep-
tion of an externally-threaded gland nut e and this gland nut is formed with an
internal central screw thread f, in which internal thread a screw down valve g of
steel, delta metal, or other suitable metal, is free to work. The working end or
face of this screw-down valve is formed with any suitable number of concentric
V shaped projections or annular cutting edges.
Above the upper surface of the copper or white metal valve seat and the under
surface of the gland nut, and surrounding the unthreaded portion of the valve spindle,
we place a hydraulic leather of the usual construction or in cases where a very
heavy pressure has to be withstood we use a packing ring of leather, woodite, or
other suitable packing material, this packing ring being externally of conical form
and for the reception of this packing ring we provide a seating ; also of conical
form in the interior of the valve casing. In the centre of the soft metal valve seat,

page_text: a small port k is provided communicating with the interior of the bottle. On the
centre line of the screw-down valve, a port is also formed or drilled extending
from the upper end to nearly the working face of the spindle, a port m at right
angles to the central port communicating with it. The upper end of the valve
spindle n is screw threaded enabling the valve spindle and with it the valve casing
to be very readily connected by means of a union joint or other form of connector
with the gas compressing pump in the charging of the bottle, or with the discharge
pipe connecting the bottle with the receiver or container to be charged during the
emptying of the bottle.
The hydraulic packing ring i and gland nut e being placed in position in the
interior of valve casing the threaded valve spindle g on being rotated will enter the
central threaded hole f formed in the centre of the gland nut e further rotation of
the spindle will cause the concentric V shaped cutting faces h or annular projections
to come into contact with the soft metal valve seating c, and in doing so the harder
metal of which the valve spindle is composed will cut into and indent the soft metal
constituting the valve seating, and so make effectual joint and close and protect the
contents of the bottle.
To liberate the contents, the valve spindle is rotated in the opposite direction to
that previously described, when the valve face leaving the valve seating will
allow the contents to pass through the small port k contained in the soft metal
seating into the space above the valve seating from whence they are conveyed by
the small ports l, m, formed in the body of the valve into the previously described
discharge pipe.
It will be seen that the formation of valve face and the harder metal of which it
is composed will ensure a true and accurate joint with the softer and more yielding
metal of the valve seating, also that the valve forms or produces its own seating,
and that this seating must be a true seating and will not deteriorate by wear. Any
suitable form of connector may be employed to connect the valve with the charging
or discharging pipes, but for charging purposes we prefer to use the connector
illustrated by Fig. 4 which is of similar construction to the valve previously
described and capable of being readily attached to or detached from the valve by
means of the winged union nut o engaging with or becoming disengaged from the
threaded portion n of the screw down valve g.
For emptying the contents of the bottle the simple form of connector shown by
Fig. 3 is convenient and effective and consists of a union tube q attachable to the
threaded portion n of the screw down valve by means of the winged union nut p as
will be understood.
We have described this invention in its application to the bottling, retention, and
liberation, of gases under very high tension, but it will be evident that our invention
is applicable as a stop and release valve for steam or water pressure.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. In a pressure resisting and regulating valve the screw-down ported valve
spindle y with annular projecting V shaped cutting edges in combination with the
softer metal ported disc c constituting the valve seat, substantially as described and
illustrated by reference to Figs. 1, 2 and 3.
2. In a pressure resisting and regulating valve the use of the leather or other
packing ring i externally of conical form and the seating for the packing ring of
internal conical formation substantially as described and illustrated by reference to
Figs. 1 and 2.
3. In combination with a pressure resisting, regulating, and connector valve, the
winged union nut capable of engaging with or becoming disengaged from the
threaded portion of the screw-down valve n as described and illustrated by reference
to Fig. 4.

page_text: 4. The general arrangement and construction of the various parts constituting
the valve for the purposes herein set forth and illustrated.
