Improved Governing Apparatus for Regulating the Pressure and
Supply of Gas and the like.
I, MARY ELIZABETH MCLENNAN, of 19, Gerrard Street, Colebrook Row,
Islington, in the County of London, Gentlewoman, do hereby declare the nature of
iny said invention to be as follows
This invention relates to improved governing apparatus for regulating the
pressure and supply of gas and the like to burners, meters or where required to be
used.
The invention has reference to that class of such governors wherein the desired regu-
lation of the gas is effected by means of an adjustable conically formed valve which
is so applied to an opening through which the gas obtains access to the burner or
where else required to be used as that it may be set to permit of only the required
quantity of gas passing in any given time irrespective of the pressure of the supply,
the valve being preferably dished on the side thereof upon which the supply acts,
and being automatically caused to more or less close the opening in accordance with
the pressure operating upon it.
Hitherto such valve has been most generally mounted on a vertically disposed
lever working on a horizontal axis and adapted with a depending fixed or adjustable
weighted part causing the appliance to as a gravity governor. Such an arrange-
ment is disadvantageous in that the gravitating influence of this weight militates
against the free action of the valve, the action of which (to be perfect) should be
dependent upon its formation and upon the pressure of the supply without being
interfered with by any such counteracting influence as aforesaid."
It has also been proposed to mount the valve upon springs but these also have a
resisting tendency which it is difficult to regulate.
The object of the present invention is to remedy these defects, and to this end
the invention consists essentially in applying or mounting the said valve to or on a
suitably supported vertical spindle whereby the aforesaid counteracting influences
are wholly avoided and the action of the valve is regulated by the influences to
which it should alone be subjected. Such supporting spindle may be mounted
either in pinned or other suitable bearings projecting from or seated in the end
covers of the mounting of the regulator, or in like bearings projecting from the gas
supply or exit tube or in any other suitable manner, and the valve may be applied
to or mounted on such spindle in combination with a lateral balancing arm projecting
from the other side of the spindle, or with an arm intended to limit its movement
away from the outlet opening to which the valve is applied, and the spindle may
also be adapted with other projecting arms by means of which and of adjustable
wires operated from the exterior the movement of the valve towards such opening
may be regulated as may be desired.

I, MARY ELIZABETH MCLENNAN, of 19, Gerrard Street, Colebrook Row,
Islington, in the County of London, Gentlewoman, do hereby declare the nature of
the said invention and in what manner the same is to be performed, to be particu-
larly described and ascertained in and by the following statement :-
This invention relates to improved governing apparatus for regulating the
pressure and supply of gas and the like to burners, meters or where required to
be used.
This invention has reference to that class of such governors wherein the desired
regulation of the gas is effected by means of an adjustable conically formed valve
which is so applied to an opening through which the gas obtains access to the
burner or where else required to be used, as that it may be set to permit of only
the required quantity of gas passing in any given time irrespective of the pressure
of the supply, the valve being preferably dished on the side thereof upon which
the. supply acts and being automatically caused to more or less close the opening in
accordance with the pressure operating upon it.
Hitherto such valve has been most generally mounted on a vertically disposed
lever working on a horizontal axis and adapted with a depending fixed or adjustable
weighted part causing the appliance to act as a gravity--governor. -Such- an-
arrangement is disadvantageous in that the gravitating influence of this weight
militates against the free action of the valve, the action of which to be perfect
should be dependent upon its formation and upon the pressure of the supply without
being interfered with by any such counteracting influence as aforesaid.
It has also been proposed to mount the valve upon springs but these also have a
resisting tendency which it is difficult to regulate.
The present invention is represented on the accompanying drawings, in which
Fig. 1 represents a sectional elevation of a regulator constructed in accordance
with the present improvement.
Fig. 2 represents a sectional elevation of the other side of the same device showing
only part of the casing attachments, and
Fig. 3 is a sectional plan view of the device through about the plane indicated by
the line a-b Fig. 1.
The object of the invention is to remedy the aforesaid defects, and to this end
the invention consists essentially in applying or mounting the said valve 4, by a
suitable connection 5, to or on a suitably supported vertical spindle 6, whereby the
aforesaid counteracting influences are wholly avoided and the action of the valve
is regulated by the influence to which it should alone be subjected. Such
supporting spindle 6, may be mounted between adjustable pins 7, carried by
bearings 8, which preferably project from the gas exit pipe 9, at a part adjacent to
the outlet opening 10, made therein, as in the modification represented. The gas
supply and exit pipe may be made in one piece stopped across internally at 11, in
a usual manner. Or such bearings may project from or be seated in the end
covers 13, of the regulator, or they may be supported in any other suitable
manner.
.
The valve 4, may also be applied to or mounted on such spindle 6, in combination
with a lateral balancing. arm 12, projecting from the other side of the spindle as in
the modification represented, or in combination with a similarly disposed arm so
shaped as to limit the movement of the valve away from the said opening 10, by
abutting against the tube 9, and either of such arms and other similar but oppositely
disposed arms with which the valve supporting spindle may be further adapted may
be adjusted and controlled, as required, by wires 14, carried by nuts 15, which may
be adjusted as required from the exterior of the regulator in a usual manner 80

page_text: that the limit of the closing movement of the valve may be adjusted as may be
desired.
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 governing apparatus of the class herein before referred to for regulating the
pressure and supply of gas and the like, applying or mounting the valve to or on a
vertically disposed axis of movement substantially as hereinbefore described.
