We, JOHN FREDERICK SIMMANCE, 40, Weltje Road, Hammersmith, W.,
Civil Engineer, and JACQUES ABADY, 18, Rockley Road, West Kensington Park, W.
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
For regulating automatically the pressure of gas to a burner, we propose fixing
in the supply pipe at a convenient position in relation to the burner a chamber
containing a diaphragm of prepared leather, silk or other flexible material, or
materials, fixed horizontally and attached by its edges to the wall of the chamber,
and from which diaphragm is depended a valve capable under certain circum-
stances of completely closing the gas conduit. To this diaphragm we attach in a
'suitable manner a tube of metal steatite glass or similar material and of a desired
weight which shall extend from below the diaphragm, this being perforated for
the purpose, to a convenient height above it. This tube shall be so shaped at its
lower end that the valve may be depended without interrupting the gas way and
its (the tube's) upper extremity prepared so as to ensure that gas issuing from it
will assume a desired form such as a jet, a circle (or the like) of jets, such as are
used in connection with incandescent burners. We propose to enclose the upper
part of the chamber with a cover (not airtight) which shall always allow the
aforesaid tube to project above it without being in any way attached to it & which
will protect the diaphragm from injury.
In action the gas passes along the supply pipe past the valve, fills the space below
the diaphragm and out through the tube in the diaphragm, but should the pressure
in the sub-diaphragm portion of the chamber exceed that required for passing the
requisite amount of gas through the aperture or apertures provided-the diaphragm
and its tube lift and the valve closes the gas supply in proportion to the outlets,
that is, in inverse ratio to the gas pressure.

manner the same is to be performed, to be particularly described and ascertained
in and by the following statement: →
For regulating automatically the pressure of gas to a burner, we propose fixing
in the supply pipe at a convenient position in relation to the burner a chamber
containing a diaphragm of prepared leather, silk or other flexible material, or
materials, fixed horizontally and attached by its edges to the wall of the chamber,
and from which diaphragm is depended a valve capable under certain circum-
stances of completely closing the gas conduit. To this diaphragm we attach in a
suitable manner a tube of metal steatite glass or similar material and of a desired
weight which shall extend from below the diaphragm, this being perforated for
the purpose, to a convenient height above it. This tube shall be so shaped at its
lower end that the valve may be depended without interrupting the gas way and
its (the tube's) upper extremity prepared so as to ensure that gas issuing from it
will assume a desired form such as a jet, a circle (or the like) of jets, such as are
used in connection with incandescent burners. We propose to enclose the upper
part of the chamber with a cover (not airtight) which shall always allow the
aforesaid tube to project above it without being in any way attached to it & which
will protect the diaphragm from injury.
In action the gas passes along the supply pipe past the valve, fills the space below
the diaphragm and out through the tube in the diaphragm, but should the pressure
in the sub-diaphragm portion of the chamber exceed that required for passing the
requisite amount of gas through the aperture or apertures provided-the diaphragm
and its tube lift and the valve closes the gas supply in proportion to the outlets,
that is, in inverse ratio to the gas pressure.
Fig. 1, (in sectional elevation) shows our invention applied to a regulator
governing the supply to the usual form of steatite flat-flame burner. In action the
gas enters at A, passes round the valve B and, filling the chamber C, C, passes
out through the openings D, D, in the tube E, and out at the steatite burner (or
ignition orifice) F. L, L, L, L, are discs of lead or any other suitable material of
any desired weight, which, with a given outlet orifice decides the pressure at
which the valve and diaphragm lift and consequently the speed at which the gas
issues from orifice F, as it will be seen that any excess of pressure beyond that
cause the
required for securing the passage of the desired amount of gas will
diaphragm G, G, to rise, and with it the tube E, to which is rigidly fixed the
valve B, which will close the gas supply in proportion to the outlet.
In the figure the issuing gas (from F.) induces an incurrent of air at the
openings H, H.
It is obvious that with a given weight L, the size of the opening F, will regulate
the pressure at which the diaphragm will commence to rise and consequently
bring the valve B into action.
Fig. 2, shows our invention (in sectional elevation) as applied to the Bunsen
burner of an incandescent gas light. The mode of action in this case is exactly the
same as in Fig. 1, except that the gas is not ignited at the tip F. It will be obvious
that as in Fig. 1, the size of the orifice decides the pressure-effect of the weights
Fig. 3, shows our invention (in sectional elevation) also as applied to an incan-
descent burner. In this case the diaphragm (which may be of metal, steatite or
any suitable material) is not fastened to the side of the chamber but is free to
slide up and down in it.
The diaphragm is so fitted as to be gas-tight, but as there is a risk of gas leaking
round the periphery, this form of governor can only be used for purposes in which
such a leak will not be greatly inconvenient.
A drop of oil may be run in the groove shown in the drawing, capillarity
ensuring soundness.
In action the gas enters at A, passes round the valve B, and into the chamber
formed by the diaphragm resting on the annular ring H, H.

page_text: From thence it passes through the openings D, D, up the tube E, and through
the orifice F.
J, J, J, are air-holes.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:
-
A gas regulator in which the point of issue at which the gas is allowed to expand
to atmospheric pressure is at a part of the apparatus connected rigidly to the
diaphragm and moving with it substantially, as herein described.
