1, JAMES HOWARTH PARKINSON, of Urmston, in the County of Lancaster, Gas
Engineer, do hereby declare the nature of this invention to be as follows:-
:―
The object of my invention is to provide a means by which cylinders or receivers
or suitable vessels may be filled or charged with compressed gas or gases without
the aid of compressors or pumps.
I provide one or two or more storage cylinders or receivers of large capacity,
which are charged with the desired gas under a higher pressure than is required in
the receiver or receivers to be filled. The cylinder or cylinders to be filled are
connected to the storage cylinder or cylinders by means of suitable taps or valves
and connections through which the gas or gases flow from the storage cylinder or
cylinders to the cylinder or cylinders to be filled until the required pressure is
obtained therein.
When by repeated or constant use the pressure of gas in the storage cylinder is
reduced below the pressure required in the cylinder to be filled, I allow as much of
the gas to pass from the storage cylinder as will do so until an equilibrium is
obtained and then by means of suitable valves, or taps or connections I complete
the charging or filling to the required pressure by allowing more of the gas to pass
from a second or third or more cylinders which still contain the gas at a pressure
over or above or equal to the required pressure.
In the case of liquid gases the storage cylinder may be slightly heated or the
receiving cylinder cooled, or water may be pumped into the storage cylinder to
lisplace the gas.
A safety valve or valves and pressure guage or guages or other means may be
dded to indicate when the desired quantity or pressure of gas is obtained in the
ylinder being filled.
The storage cylinder may be made of any desired capacity or size that can be
eadily transported from place to place, and thus a stock or supply of com-
ressed gas can be maintained at any desired centre from which the small or portable
linders can be refilled without the necessity for expensive plant as at present
xists and at the same time the operations are carried out with much greater safety
those employed; no heat being generated by the passage of the gas from the
orage cylinder to the receiver cylinder, as is the case when the gas is pumped and
mpressed.

COMPLETE SPECIFICATION.
Improvements in the Filling of Cylinders or other Receivers with
Oxygen, Hydrogen, Coal, Oil, and other Gases or Mixtures of
Gases under Pressure.
I, JAMES HOWARTH PARKINSON, of Stretford, in the County of Lancaster, Gas
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:-
-
The object of my invention is to provide a meaus by which cylinders or receivers
[P1

page_text: or suitable vessels may be filled or charged with gas or gases under pressure or in a
liquid state without the aid of compressors or pumps.
"The invention will be fully described with reference to the annexed drawings.

I provide one two or more storage cylinders A. of large capacity capable of
resisting a high internal pressure. The cylinders A. are mounted in a suitable frame
or stand B in which they can be easily placed and from which they can be readily
removed, provided with suitable connections valves and taps whereby the cylinders A
may be connected to the cylinders C which are to be filled.
The pillars b support two cradles D into which the storage cylinders A. are placed
and by which they are held and supported. The cradles D oscillate on pivots or
trunnions d upon which they can be turned over to any angle to receive or discharge
the cylinders A by the worm E and quadrant e actuated by the hand wheel E.
The various sized cylinders A are held in position in the cradle D by the screws (1.
When it is desired to place a storage cylinder in position or remove one the cradle
is tilted over until the cylinder can be easily drawn from or placed into the same
by means of a trolly. In front of the cradles and cylinders there is placed a
table F upon which the small or ordinary cylinders G (into which gas is transferred
for commercial or other purposes) rests while being filled. The storage cylinders
are both connected by the pipes h' to the valve H through which the gas flows
from the large storage cylinders A. to the small cylinders C. Both the large storage
cylinders and the small cylinders are fitted with valves of the usual form. The
valves of the storage cylinders A are opened by the taps J and the pipes
connected thereto by unions or couplings j.
are
The small cylinder C which is to be filled rests upon the table F and is held in
position by the screw clip N whilst being filled the valve in the end being opened
by being pressed down upon the end of the pipe G. On the pipe G is a tap y to
prevent air filling the pipe or the escape and waste of the gas therein when the end
is released and the tap J turned off.
The valve His connected to the small receiving cylinder C by the pipe G and
is constructed to prevent too great a pressure being exerted upon the cylinder C.
It is formed with a small valve K preferably formed of the pointed end of a spindle
which at its other end carries a piston K¹ of considerably larger diameter upon
which the gas acts to close the valve when the pressure above the piston is sufficient
to overcome the spring (adjusted to close at certain fixed pressures).
The valve H being thus automatically closed, the valve attached to the small
cylinder C also the stop valve g between the same and the valve H, are closed by
hand. The small cylinder being now charged with gas at the desired pressure is
removed. To refill another small cylinder I place the same upon the table F and
connect its valve by means of the screw clip to the pipe G leading from the valve H
open the valve on the small cylinder and re-open the stop valve between the same
and valve H thus relieving the pressure on the piston K' and permitting the spring
to open the valve H. The small cylinder C is thereby connected with the large
storage cylinder A. until the pressure accumulates sufficiently in the small cylinder C
and above the piston K' to again overcome the spring and close the valve H.
Upon the top of the chamber is placed a pressure gauge M to indicate the
pressure in the cylinder C and a safety valve is provided to prevent an excessive
pressure accumulating in the cylinder C should the valve H from any cause fail
to work.
Pressure gauges may be used if desired on each of the storage cylinders A to
indicate the pressure contained therein.
When by repeated or constant use the pressure of gas in one of the storage

page_text: A is reduced below the pressure required in the cylinder C I allow a
much of the gas to pass from the storage cylinder as will do so until an equilibrium
is obtained and then by means of the tap or valve adjacent to the storage cylinde
containing a reduced pressure, I close the connection therewith and open the tap to
5 connect the other storage cylinder and complete the charging or filling of the smal
cylinder to the required pressure by allowing more of the gas to pass from a second
or third or more cylinders which still contain the gas at a pressure over or above or
equal to the required pressure for commercial or other purposes.
In the case of those gases kept liquid by pressure the temperature of the large
O storage cylinder may be slightly increased by heat so as to vaporize sufficient
quantity of gas to charge the portable cylinder or a connection may be made with
the lower part of the large storage cylinder so as to convey the gas in a liquid state
to the small portable cylinders by the liquid gas being driven over by the pressure
of the gas above the liquid in the large storage cylinder.
Water may if desired be pumped into the storage cylinder to displace the gas
when the pressure is reduced.
The storage cylinders A may be made of any desired capacity or size that can
be readily transported from place to place and thus a stock or supply of compressed
or liquified gas can be maintained at any desired centre from which the small or
portable cylinders can be refilled without the necessity of waiting for days and the
expense of carriage, without the necessity for the expensive plant as at present
exists and at the same time the operations are carried out with much greater safety
to those employed; no heat being generated by the passage of the gas from the
storage cylinder to the receiver cylinder as is the case when the gas is pumped and
compressed.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. Apparatus for filling portable cylinders or receivers with gas in a compressed
or liquified state from large storage cylinders in which the gas is very highly com-
ressed constructed and arranged substantially as described and shown.
2. The process for charging or filling portable cylinders or receivers with com-
ressed or liquified gas which consists in first pumping or compressing the gas into
orage cylinders at a very high pressure-much higher than required for use or in
e portable cylinders-and then filling such portable cylinders from the storage
linders substantially as described.
3. Apparatus for filling portable cylinders or receivers with gas in a compressed
liquified state from large storage cylinders having the supporting stands for the
orage cylinders the valve H connecting pipes the table F for the portable
linder pipe y and clip N substantially as described.
