Improvements in Gas Governors.
I, JOHN GOODSON, Gas Engineer, of 13, Maze Pond, S.E., in the County of
London, 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:-
1
This invention for improvements in gas governors relates to that class of
governor
which is usually connected directly to the burner and in which the opening of a
supply valve or passage is regulated by means of a floating diaphragm.
In the accompanying sheet of drawings: Fig. 1 is a vertical section of a
governor suitable for an ordinary burner; Fig. 2 is a similar view to Fig. 1 of
a governor provided with means for varying the supply. Fig. 3 is a sectional
elevation of governor suitable for down current supplied to regenerative or other
suspended lamps. Fig. 4 is a vertical section of a modified arrangement of gover-
nor and especially suitable for gas stoves.
Referring to Fig. 1 of the drawings, a casing a is provided with screw threaded
socket b, for connecting it to the gas supply pipe, and with a broad cylindrical
chamber c in which works a floating diaphragm & having a central tube c working
freely in a guide diaphragm f fitting into the upper part of the chamber c and
being surmounted by a cap g having perforations for the passage of the gas to
the burner. The chamber c is placed in communication with the supply by means
of a perforation in the tube c. A gauze wire diaphragm is stretched across
the lower part of the chamber c and is firmly secured by a spring ring m. So
long as the supply pressure remains normal the float & remains in its lowermost
position admitting a full supply of gas to the burner, but should this pressure be
increased it acts on the underside of the float d and raises it, thereby causing the
upper orifice of the tube e to approach the valve projection on the cap g in the
chamber and throttle the supply until the pressure is reduced to the normal,
the rate of gas consumption being determined by the diameter of the tube & or
its inlet orifice o as will be readily understood.
In the modified arrangement shown in Fig. 2 the gas passes through a socket h,
gauze diaphragm and passage ol (provided with a regulating screw p' by means
of which its effective area may be adjusted to suit different consumptions and
qualities of gas) to a cylindrical chamber c', in which the floating diaphragm d¹
works. The lower end of the tube e forming part with the floating diaphragm d'
is blocked, the gas passing from the chamber c¹ to the interior of the tube e
through a perforation and thence to the chamber as in the arrangement
shown in Fig. 1.

In the arrangement of governor shown in Fig. 3 the gas enters from the supply
pipe at the screwed socket 62 passing through gauze diaphragm annular space s
and passages into the chamber te and through passages o into the chamber and
thence through the tubular part es of the float to the socket & connected to the
burners. The lifting of the floating diaphragm de causes the orifice of the tube e³
to approach the projection n³ of the diaphragm and thereby throttle the supply

regulated by means of a regulating screw p passing through the casing as opposite
to the passage o³, the accurate relative positions of the casing a² and chamber c³
being maintained by the fixed screw y all as clearly shown.
In the arrangement of governor shown in Fig. 4 the gas enters the
and passing through tube e and into the chamber formed by the screw casing
passage 64
cap a, holes h in cover g' and thence through passages and a to the burner,
its action being similar to that described with reference to Fig. 1. When desired
this governor may be constructed with a regulating screw similar to the arrange-
ment shown in Fig. 2.
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 :-
1. A gas governor in which the supply is regulated by means of a floating
diaphragm, the whole arranged and constructed substantially as described und
shown in Fig. 1 of the drawings.
2. A gas governor in which the supply is regulated by means of a floating
diaphragm, the whole arranged and constructed substantially as described and
shown in Fig. 2 of the drawings.
3. A gas governor in which the supply is regulated by means of a floating
diaphragm, the whole arranged and constructed substantially as described and
shown in Fig. 3 of the drawings.
4. A gas governor in which the supply is regulated by means of a floating
diaphragm, the whole arranged and constructed substantially as described and
shown in Fig. 4 of the drawings.
