JOHN FREDERICK SIMMANCE Elm Villa Royal Road Teddington Middlesex, Engineers
Traveller and CHARLES REVILL, BELLAMY, Princes Park, Liscard, Cheshire, Gas
Engineer do hereby declare the nature of this invention to be as follows:-
An improvement in the method of automatically regulating downward or other
currents of gaseous bodies, & which improvement is capable of application to any
existing class of gas regulator in which the governing power is exerted by varying
positions of a disc, cap, float, diaphragm or other form of valve. Our improvement.
consists in allowing the gas to enter from above the disc, cap, float, diaphragm or
other form of valve & to pass by means of an inlet duct through the centre of the said
disc, cap, float, diaphragm or other form of valve into the chamber or reservoir
beneath from whence it obtains exit by the means adopted in the class of regulator to
which our improvement may be applied, the inlet duct may or may not be used as a
guide rod for ensuring the accurate centering of the disc, cap, Hoat, diaphragm or
other form of valve, & may be formed in any suitable manner with view to use as a
valve seat for actually effecting at this point the automatic regulation of gas (in con-
junction with a suitable form of disc, cap, float, diaphragm or the like) or by means
of a screw or sliding action may be used as a method of adjusting the quantity of
gas passing through the regulator or may be used wholly & solely as an inlet or for
the above named purposes collectively or in any combination.

An Improvement in Gas Regulators.
CHARLES REVILL BELLAMY, Gas Engineer, Princes Park, Liscard, Cheshire, JOHN
FREDERICK SIMMANCE, Gas Engineer, Elm Villa, Royal Road, Teddington, Middlesex,
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 consists of a simple method of conducting the Gas, (the downward
current of which it is desired automatically to regulate,) to a suitable point in the
regulator for allowing any excess of pressure to exercise its motive power upon a
suitably constructed throttling valve, which may be in the form of, or attached to, a
float, dise, or diaphragm of any suitable material. This improvement in the con-
duction of downward currents of Gas is effected by the insertion of an inlet tube,
which passes vertically through the centre of the float, disc, diaphragm, or valve, but
does not necessarily go beyond it in either direction. This central inlet Tube may
rise with the float, disc, diaphragm, or valve, or may remain rigid. It may be used
as the throttling valve, as the seat for the throttling valve, as a guide rod to ensure
the accurate rising or falling of the float, disc, diaphragm, or valve, or may simply
fill its primary office as a means of conducting the gas to the required point in the
regulator, or it may be used for any of these purposes in combination, & may be as
long or as short as may be necessary to allow the gas to obtain inlet passage through
& from above the float, disc, or diaphragm, to either of which it may or may not be
It may be constructed in metal, glass, leather, silk, or any other suitable
attached.
material.
We will now proceed to describe, with reference to the accompanying drawings
some of the applications of our invention.
Fig. 1 Shows our invention, in sectional elevation, applied to a regulator with a
float that is itself the throttling valve. Gas enters at A, passes downwards through B,
(the central inlet Tube,) to the chamber C, beneath the float D. D, from which point
the action becomes similar to that of the ordinary form of regulator.
Fig. 2, Shows our invention, (in sectional elevation.) the central tube itself used
as a valve seat.
Gas enters at A, passes downwards through B, (the central inlet Tube,) & passes
round the conical valve Cinto the chamber D. D. beneath the Table-Disc E. E. E. E.
where, should the pressure of gas be in excess of that required for securing the further
passage of the desired amount through the fixed orifices F. F, or other suitable
apertures, the table-disc E. E. E. E. is raised, & the attached valve, C, is brought into
action, reducing the outlet of the central inlet tube B in proportion inversely to the
pressure, thus securing an uniform discharge for consumption.
"
Fig. 3, in sectional elevation, shows our invention applied to what is generally
known as a
diaphragm regulator, & in this instance tlie central inlet tube itself
forms the throttling valve, rising when necessary, to a conical seat.

page_text: Gas enters at A, passes round & under the conical seat B, through the central
tube C, (which is attached by a flexible joint D. D. to a convenient part of the case
of the regulator,) into the chamber E. E., where, should the pressure of the gas be in
excess of that required for securing the further passage of the desired amount, through
the fixed orifices F. F. or other suitable apertures, the diaphragm G. G. expands or
is inflated, & the central tube C. being attached, is brought into action in its capacity
as a valve, reducing the inlet to the chamber E, E. in inverse proportion to the
pressure of the gas, thus ensuring an uniform discharge for consumption. The
annular space H. H. communicates with the atmosphere. The conical valve seat, B,
is attached by means of a rod with an adjustable screw, to the bottom of the
chamber E. E.
Having now particularly described & ascertained the nature of our said invention,
& in what manner the same is to be performed, we declare that what we claim is :-
The use of an inlet tube passing centrally through the disc, float, valve, or
diaphragm, of a gas regulator, through which tube gas passes downwards, & which
tube may be of any required length or diameter, & either rigid, or moveable, & of
any suitable material.
In witness whereof we the said Charles Revill Bellamy & John Frederick Simmance
have hereunto set our hands & seals this eleventh day of January in the year of our
Lord one thousand eight hundred & eighty seven.
