An Improved Gas Regulator or Governor.
1, JOHN HORAN HIGGINSON of 105 Newport Street, Bolton in the County of
Lancaster, Funeral Undertaker, do hereby declare the nature of iny said invention
to be as follows:-
:-
This invention relates to an improved gas regulator or governor and consists in
providing a metallic case in halves provided with inlet and outlet orifices and a
Hexible diaphrage. The inlet portion of the metallic case is provided with a valve
seat in conjunction with which operates a conical or other valve mounted on a
screwed spindle, the latter being attached to the diaphragm by a threaded nut
secured in any convenient manner. By means of the screwed spindle the movements
of the valve may be regulated to a nicety according to gas pressure and require-
ments, thereby dispensing with the old or present system of regulating the same by
a series of weights. The upper end of the metallic case is provided with a screwed
or other cover to allow of the screw being operated to regulate or adjust the valve
as desired.

An Improved Gas Regulator or Governor.
I, JOHN HORAN HIGGINSON of 105 Newport Street, Bolton in the County of
Lancaster, Funeral Undertaker, do hereby declare the nature of my said invention
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
This invention relates to an improved gas regulator or governor and consists in
providing a metallic case in halves provided with inlet and outlet orifices and a
flexible diaphragm. The inlet portion of the metallic case is provided with a valve
seat in conjunction with which operates a conical or other valve mounted on a
screwed spindle, the latter being attached to the diaphragm by a threaded nut secured
in any convenient manner. By means of the screwed spindle the movements of the
valve may be regulated to a nicety according to gas pressure and requirements,
thereby dispensing with the old or present system of regulating the same by a series
of weights. The upper end of the metallic case is provided with a screwed or
other cover to allow of the screw being operated to regulate or adjust the valve as
desired.
Fig. 1 is a sectional elevation of my improved gas regulator or governor, and
Fig. 2 is a plan through line A. B.
The gas regulator or governor consists of the metallic case C made in halves
provided with the flanges D and jointed together by the screws E. The bottom
portion of the metallic case C is provided with the inlet orifice F and the outlet
orifice G, each having a union H to connect them to the ordinary gas pipes.
Between the flanges D of the metallic case C is fixed the flexible diaphragm K, to
which is attached the threaded nut L in which is mounted the screwed spindle M.
To the bottom end of the latter spindle is fixed the conical valve N to operate in
conjunction with the valve seat O in the inlet orifice F. To prevent the spindle M

page_text: turning it is locked by the nut R. By means of the screwed spindle M the move-
ments or position of the valve N may be regulated in either direction to the greatest
nicety according to gas pressure and requirements, thereby dispensing with the old
or present system of regulating the same by a series of weights. The upper end of
the metallic case C is provided with the cover P to allow of the screw M being
operated in either direction to regulate or adjust the valve N as desired according
to requirements. This gas regulator or governor is simple in its action and prevents
the flaring of gas lights through the constantly varying pressure of gas which is
partly owing to the irregularity of street mains, and more particularly so in places
where the latter are too small or little to supply the great and fluctuating demands
for mills and other works.
This improved gas regulator or governor operates in the following mauner :-
When the full quantity of lights are burning that it is set for the pressure on the
diaphragm K is nil, or almost so, and the valve N is full open, as shown in Fig. 1,
to pass the requisite amount of gas. In case a number of lights are turned out and
the demand from the outlet G is reduced the pressure from the inlet orifice F
operates on the underside of the diaphragm K and lifts the same, by which action
the valve N rises towards its seat O and contracts the area just sufficient to allow of
the passage of gas
to keep the remaining lights burning in their normal condition
to prevent flaring and waste. In case more lights are put in operation the
diaphragm K drops and opens the valve N to pass the requisite amount to give
uniform lights according to the demands of the various burners employed, which
is performed automatically by the regulator or governor without the slightest
attention. In case all the lights are turned out the pressure of gas through the
inlet orifice F will raise the diaphragm K so high as to close the valve N against
its seat O, at which point it will remain until a supply of gas is required to pass
through the outlet orifice G.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In combination with the metallic case C of a gas regulator or governor the use of
the flexible diaphragm K, screw M, and nut L for automatically opening and closing
the valve N according to the amount of gas required, substantially as described and
as illustrated in the drawings.
