Improvements in Gas Regulators.
I ALFRED CHRISTOPHE TOBLER, of 12 Rue de la Bourse, Paris, France,
Gas Regulator Manufacturer 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 :-..
This invention relates to a self-acting gas regulator of extremely simple
construction, capable of efficient working even at the lowest pressures, and of
indefinite durability, its working parts being hermetically enclosed.
Reference is to be had to the accompanying drawing, which illustrates an example
of the regulator; Figure 1 being a longitudinal vertical section, Figure 2 a vertical
cross-section of the lower part, on line 1-2, Figure 1, and Figure 3 a horizontal
section, on line 3-4, Figure 1.
The same letters of reference denote like parts in all the figures.
The casing a, a, is provided with gas inlet orifices b, 1, (one or other being closed
by a screw plug c according as the regulator is placed upon or beside the meter)
and with a gas outlet, an outlet closed by another screw plug d being also
provided for the water of condensation deposited in the pipes. Within the casing a
à bell chamber e preferably of aluminium dips into an annular mercury trough
comprised between the side of the casing a and the inwardly and upwardly
projecting flange f formed in one with a. The bell e is affixed by out k to a central
vertical rod g carrying a balanced or deuble beat valve h, closing against
seats i, i', of a valve box r screwed into the central chamber; which communicates
works
by passage j, with the gas inlet bor b. The lower end of the valve rod
in a suitable guide and the valve rod is loaded by weights m resting on a collar 1,
the load being adjusted for the purpose of regulating the supply, according to the
number of burners and of preventing the gas in excess from passing into the bell e,
and thus avoid any increase in the consumption due to too great a pressure.
Upon the inner wall of the mercury trough is fixed a diaphragm n provided
with a ceutral aperture to give passage to the valve rod and access of the gas to
the interior of the bell, and the casing a is enclosed by an inner domed cover o to
prevent the admission of dust provided with a filling orifice above the mercury
trough and with a central aperture for the valve rod to slide through, this cover
being in turn enclosed by the outer cover p provided with a dome or chamber in
which the weights m are enclosed. This dome p carries the downwardly projecting
guide socket t and is surmounted by a pressure gauges whose index is actuated by
the upper end of the valve rod g bearing against the spring contained within said
socket t.
The gas on entering the regulator either at 6 or 6', raises the bell e and stem g,
which upward movement compresses the spring of the pressure gauge and transmits
the movement to the index hand.
The regulator may be placed at any point on the gas supply pipe, but preferably
near the meter.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. A gas regulator consisting of the combination of a bell e dipping in mercury
contained in an annular trough formed by an annular flange ƒ cast in one with the

page_text: casing a, double beat valves h¹ contained in a valve box r screwed into a chamberj
so as to regulate the supply and prevent any increased consumption resulting from
excessive pressure, the valve stem 9 being fixed to the belle and loaded with
weights m for regulating the pressure to suit the requirements of the consumption,
as hereinbefore described and illustrated in the drawings.
2. In a gas regulator of the kind specified in the preceding claim, the combination
of a pressure gauges and the spring actuating the index hand thereof, with the
belle and valve stem g which by rising in socket t compresses the said spring and
moves the index hand, the variations of pressure thus indicated enabling the
consumption to be regulated and the gauge also indicating leakage when the gas is
not burning, as hereinbefore described and illustrated in Figure 1 of the drawings.
