Improvements in Valves for Controlling the Inlet and Outlet of
Compressed Liqueflable Gases To and From Metallic Storage
Cylinders or Vessels.
We, HOWARD LANE, of Corporation Street, Birmingham, in the County of
Warwick, Engineer, and JOHN PULLMAN, of Greek Street, Soho Square, in the
County of Middlesex, Manufacturer, do hereby declare the nature of this invention
to be as follows:-
The improvements which form the subject of the present invention relate more
especially to valves used in the manipulation of gases which under pressure become
partially or wholly liquefied. The increased utilization of such gases, as for
instance carbonic acid, entails the use of the substance both in gaseous and liquid
condition at the option of the user, from the same storage cylinder or vessel. For
example, to aërate liquids, carbonic acid in a gaseous condition passing in some
cases through an automatic regulator is needed, whilst to produce cold artificially,
to make ice creams, to cool wine, and for other useful purposes, the carbonic acid
should be in liquid condition.
Our present improvements consist in the construction and application of double
valves to the storage reservoirs or vessels containing gases as described. The
double valves are contained in a chamber having two outer orifices provided with
unions or other means for connecting them with exterior pipes or apparatus and two
inner orifices one of which is extended to the bottom of the reservoir or cylinder
by means of a tube and is therefore capable of conducting liquid gas from the
lower levels where it collects by gravitation, whilst the other interior orifice opens
immediately into the neck or highest portion of the reservoir or cylinder so that
gas only is withdrawn.
The inner and outer orifices described are connected by passages which are
opened or closed at pleasure with screw plugs or stoppers by well known means.

COMPLETE SPECIFICATION.
Improvements in Valves for Controlling the Inlet and Outlet of
Compressed Liqueflable Gases To and From Metallic Storage
Cylinders or Vessels.
We, HOWARD LANE, of Corporation Street, Birmingham, in the County of
Warwick, Engineer, and JOHN PULLMAN, of Greek Street, Soho Square, in the
County of Middlesex, Manufacturer 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 and accompanying drawing, that is
to say :-
The improvements which form the subject of the present invention relate more
especially to valves used in the manipulation of gases which under pressure become
partially or wholly liquefied.
The increased utilization of such gases, as for instance carbonic acid, renders it
advantageous or necessary to use the substance both in a gaseous and a liquid
condition, at the option of the user, from the same storage cylinder or vessel. For
example, to aërate liquids, carbonic acid in a gaseous condition, passing in some
cases through an automatic regulator, is needed, whilst to produce cold artificially,

page_text: to make ice creams, to cool wine, and for other useful purposes, it is preferable that
the carbonic acid should be in a liquid condition.
Our present improvements consist in the construction and application of double
valves to the storage reservoirs or vessels containing gases as described so that
their contents may be drawn off either in a liquid or gaseous form as may be
desired.
The accompanying drawing is in illustration of our invention, Figure 1 being a
vertical section through the double valves, Figure 2 a plan, and Figure 3 a view of
the apparatus on a smaller scale.
'The same letters refer to the same parts in the different figures.
The double valves a, b, are contained in a chamber c having two outer
orifices d, e, provided with unions or other equivalent means for connecting them
with exterior pipes or apparatus (such as d, e, Figure 3) and two inner orifices one
of which g is extended to the bottom of the reservoir or cylinder & by means of a
tube (Figure 1) and is therefore capable of conducting liquefied gas from the
lower levels where it collects by gravitation, whilst the other interior orifice i opens
immediately into the neck or highest portion of the reservoir or cylinder k so that
gas only is withdrawn.
The inner and outer orfices described are connected by passages the valves a
and b in which are opened or closed at pleasure by means of screw plugs or stoppers
in the ordinary well known way, as shewn, or by other equivalent means.
Instead of using two separate outer discharge orifices at d and e each connected
with one of the inner orifices g, i, by the valves, one single discharge orifice (such
as d or e) may be used, and may be connected as desired with either the liquefied
gas at the lower part of the vessel k, by one of the valves, or with the compressed
gas in the upper part of the vessel, by the other valve, so that either the
liquefied gas, or the compressed gas can be delivered as desired, from the same
discharge orifice.
The several parts of the apparatus are made of metal or other material capable
of resisting the great pressure of the gas, and we do not confine ourselves to the
precise form, proportions and details, which may be varied more or less to suit the
particular circumstances in which the apparatus is to be used, but
Having now particularly described and ascertained the nature of the said inven-
tion and in what manuer the same is to be performed, we declare that what we
claim is :-
1. In connection with vessels containing compressed liquefiable gas, the use of
double valves, one of which is connected on one side with the lower part of the
vessel and on the other side with a suitable discharge aperture, for drawing off
liquefied gas, whilst the other valve is connected on one side with the upper part
of the vessel and on the other side with another suitable discharge aperture, for.
"drawing off compressed gas, substantially as described and illustrated.
2. As a modification of the arrangement described in Claim 1, the use of a single
discharge aperture which can be connected by one of the valves with the lower
part of the vessel, and by the other valve with the upper part of the vessel, for
drawing off liquefied gas, or compressed gas, through the same discharge aperture,
substantially as described.
3. The combination with a vessel containing liquefied gas, of the chamber c,
containing valves a, b, an inner orifice y extending to the bottom of the vessel, and
an inner orifice i communicating with the upper part of the vessel, an outer orifice
or orifices d, e, and means for opening and closing the valves a, b, as desired,
substantially as and for the purpose described, and shewn in the drawing.
