PROVISIONAL SPECIFICATION.
Improvements in Regulators for Compressed Gas.
ALFRED SUITER, 65 Chancery Lane, London, Middlesex Mechanical Engineer,
and ALFRED RUSSELL MARGARY, 9 Wynne Road, Brixton, Surrey, Mechanical
Draughtsman, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to regulate the pressure of gas issuing from
compressed gas vessels, to any pressure that may be desired (short of the pressure
in the vessel) no matter what the pressure in the vessel may be; also to regulate
such issuing gas, so as to be adjustable and under the control of the operator, so
that the pressure can be increased or decreased at will.
In carrying out our invention, we employ a suitable casing for connection to
valve of compressed gas vessel, in this casing we fit a gas tight diaphragm, under
which is a lever of the first kind, the fulcrum of which is placed at any suitable
distance from the end, (according to the leverage required to close the valve) on
one end of such lever is fitted a valve to control the flow of gas from the vessel, the
other end of the lever is fitted with a suitable screw and clamping nuts to connect
it to the diaphragm.
.
;
To render the issuing pressure of gas adjustable at will, we provide the screw
connecting the lever with the diaphragm, with a pointer, by turning which adjusts
the distance of the valve from its seating, so causing the diaphragm to spring more
or less before it closes or opens the valve emitting the gas from the vessel. Such
pointer being provided with a suitable divided quadrant, the pressure of the issuing
gas can be read off at a glance.

COMPLETE SPECIFICATION.
Improvements in Regulators for Compressed Gas.
ALFRED SUITER of 65 Chancery Lane London in the County of Middlesex
Mechanical Engineer and ELLEN EMMA MARGARY of 9 Wynne Road Brixton
in the County of Surrey, Widow, Administratrix to the estate of the late Alfred
Russell Margary, 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 this invention is to regulate the pressure of gas issuing from
compressed gas vessels, to any pressure that may be desired (short of the pressure
in the vessel) no matter what the pressure in the vessel may be. Also to regulate
such issuing gas so as to be adjustable and under the control of the operator, so
that the pressure can be increased or decreased at will.
In carrying out our invention we employ a suitable casing for connection_to
valve of compressed gas vessel, in this casing is fitted a gas tight diaphragm, under
which is a lever of the first kind the fulcrum of which is placed at any suitable
distance from the end according to the leverage required to close the valve. On
one end of such lever is fitted a valve to control the flow of gas from the vessel.
The other end of the lever is fitted with a suitable screw and clamping nuts, to
connect it to the diaphragm.
To render the pressure of the issuing gas adjustable at will, we provide the screw
connecting the lever with a pointer, by turning which, adjusts the distance of the

valve from its seating, so causing the diaphragm to spring more or less before it
closes or opens the valve, emitting the gas from the vessel. Such pointer being
provided with a suitable divided quadrant the pressure of the issuing gas can be
read off at a glance.
That our invention may be more clearly understood reference may be made to
the accompanying drawing, in which,
Fig. 1, is a part sectional elevation and Fig. 2, a plan with cap removed of a
regulator for compressed gas, constructed, according to our invention.
A is a casing with screw B for connecting to valve of compressed gas vessel,
a, is a diaphragm, b, is the screw and clamping nuts, c, is the lever, and d, is the
fulcrum to control the flow of gas from the vessel by the valve e. f, is the pointer
for adjusting the pressure of the issuing gas, g, is the divided quadrant for indicating
the pressure of the issuing gas.
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 :-
1st. In regulators for compressed gas the use of a lever, c, in conjunction with a
concentric diaphragm, a, fulcrum, d, and valve, e.
2nd. In regulators for compressed gas the use of a pointer, f, for adjusting and
shewing the issuing pressure of gas.
3rd. The general construction of regulator for compressed gas as herein described
and illustrated by the accompanying drawing.
