1 GEORGE BRIER FEARNLEY Engineer 55 Millbrook Road Brixton in the County
of Surrey do hereby declare the nature of this invention to be as follows:-
Improvements in Gas Regulators for obtaining the Heighest Illuminating power, the
Fullest carbonic combustion the Greatest amount of cleanness combined with the
Lowest Registeration of the meter, the most complete principle for Safety. This
apparatus is worked by Hydraulic pressure gauge which can be fixed in any part of
the Establishment thus making the consumer independent of any over pressure
which may be forsed through the main, which is indicated on the Gas Gauge.)
I attach to the gas pipe in any convenient place a Hydraulic Guage which shows
on a scale marked on a suitable case containing the Guage the pressure of the Gas
forsed through the mains. Running up each side of the case inside the same are two
racks each attached at its lower end to wiers leading to the Meter Tap. The right
hand rack tending when Raised to close the Meter Tap, the left hand rack tending
when raised to open the same, these racks are worked by the same pinion, at about
the middle of their lengths and to the axis of the pinion is attached a suitable
key for actuacting the Racks. To the top of the left hand Rack is fixed an
indicating hand pointing to a Scale on the upper part of the case above that of the
Hydraulic pressure guage which scale showes the state of the Meter Tap Guage full
on &, & off, as the pressure through as indicated by the pressure guage increases
the before mentioned key is turned so as to raise the right Rack and turn off the
Meter Tap untill the pressure as indicated by the guage is that required to give the
maximum Light without an excess of pressure.

page_text: I, GEORGE BRIER FEARNLEY of 55 Millbrook Road, Brixton, in the County of
Surrey, Gas Engineer, 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 :-
My invention for improvements in gas regulators has for object to provide efficient
mcans whereby the pressure of the gas to be consumed can readily be regulated from
any convenient place to the required degree to give the maximum of illumination
for the minimum consumption of gas whatever the pressure of gas in the mains
may be.
Apparatus constructed according to my invention consists of the combination of a
pressure gauge for determining the pressure of the-gas to be consumed, with means
for operating the ordinary meter or other suitable supply tap or cock for regulating
the pressure as required. The apparatus is fixed in any convenient place and the
pressure gauge is connected to the gas supply pipe to indicate the pressure at which
the gas is being consumed. Two racks capable of sliding longitudinally in the
framing of the apparatus are operated by a pinion arranged centrally between them
and are connected by cords or wires to the opposite ends of a lever or to a pulley
secured to the plug of the aforesaid tap or cock. It will thus be seen that by operating
the pinion by means of a handle or key, the tap or cock can be turned to admit more
or less gas to regulate the pressure of the gas to be consumed so as to give the
maximum amount of illumination, this point being indicated on the pressure gauge.
A pointer attached to one of the racks moves over a graduated scale and shows the
position of the plug of the supply tap or cock.
In the accompanying sheet of drawings
Fig. 1 is a front elevation of apparatus constructed according to my invention, and
Fig. 2 is a sectional side elevation of the same.
The pressure gauge consists of a bent tube formed partly of metal a and partly of
glass b. The tube a is connected to the gas supply pipe, which contains or is to contain
the gas at the pressure at which it is to be consumed, through the small tap or cock c.
The top of the glass tube b is closed by a metal cap d which is perforated with a
small hole. The tube a contains a small quantity of water at its lower bend. It will
thus be seen that when the gas is admitted through the cock c, this water will be
caused to rise in the glass tube b behind which is a suitably graduated scale to indicate
the pressure as clearly shown or the tube itself may be graduated. The means for
operating the meter or supply cock comprises two racks e capable of sliding in the
framing and gearing with a pinion g arranged centrally between them. The pinion g
is fixed on a spindle h which can be turned in either direction by means of a handle
or key. When the pinion 9 is turned in one direction or the other, the two racks e
slide in the opposite direction. These said racks are connected by cords or wires to
the opposite ends of a lever or to a pulley secured on the plug of the meter or supply

page_text: cock admitting the gas to the supply pipe, the pressure in which is to be regulated.
One of the racks e has fixed to it a pointer m moving over a graduated scale to
indicate the position of the meter or supply cock. The pressure gauge and racks
and operating mechanism are arranged in the framing which is graduated as shown
and is provided with a slot n for the pointer m, a slot o for the pressure gauge a band
with suitable holes for the spindle h, tube a and wires or cords ...
In using my apparatus the cock or tap c is turned to admit the gas to the tube a
and the spindle c is then turned until the pressure as indicated by the height of the
water in the tube b is at the required degree. It will thus be seen that the gas can
be consumed at the most economical pressure and that this pressure can readily be
regulated from any suitable room or place, the apparatus being only connected to the
meter or supply cock through the two cords or wires which can be run as desired and
which are not liable to break or become deranged as the pull on them is in the direct
line of their length.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is :-
1. The arrangement of apparatus for regulating the pressure of gas to be consumed
consisting of a pressure gauge for determining the said pressure and of means for
operating the meter or other supply tap or cock for admitting the gas, the said
apparatus being arranged in any suitable place and connected with the said tap or cock
by wires or cords substantially as described.
2. The construction of apparatus for regulating the pressure of the gas to be
consumed substantially as described with reference to the drawings.
