PROVISIONAL SPECIFICATION.
A Combined Pressure Regulator and Stop Valve for Gas Supply.
I, ALFRED TOBLER, of 12, Rue de la Bourse, Paris, France, Gas Regulator
Manufacturer, do hereby declare the nature of this invention to be as follows:-
My invention relates to apparatus adapted to act either as a pressure regulator
or stop valve for gas mains. The apparatus consists essentially of the combina-
tion with a floating bell chamber and double beat valve controlling the admission
of gas to the bell whereby to obtain a constant pressure, of a device for enabling
the regulator to act as a stop valve.
Reference is to be had to the drawings accompanying this Specification
wherein Figure 1 represents a vertical section of the apparatus.
is a half plan, half longitudinal section on line A B Figure 1
Figure 2
a is the casing having gas inlet and outlet orifices bc. d is the bell which dips
into a bath of mercury contained in an annular channel e within the casing a.
The bell d is fixed to the stem f of a double beat valve g g and is loaded with
weights h for regulating the outflow pressure of the gas. The stem f is con-
nected by a link i at its upper end with a shackle k attached to a regulating
screw turning in a nut mounted in the cover m and operated by a hand wheel n.
When the screw is in its lowest position the valves g will be removed from their
seats and give passage to the gas, in which position the bell floats and is free
to rise and fall under variations of pressure, the links ik allowing freedom of
vertical movement sufficient in extent to allow the valve to pass from the closed
to the full open position. By raising screw until the valve is closed as shewn
in Figure I, the bell d which is also raised will be rendered immovable and the
flow of gas to the main will be shut off.

I, ALFRED 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:-

the regulator to act as a stop valve.
Reference is to be had to the drawings accompanying my Provisional Specifica-
tion wherein Figure 1 represents a vertical section of the apparatus. Figure 2
is a half plan, half longitudinal section on line A B Figure 1.
a is a casing having gas inlet and outlet orifices b c and d is the bell which dips
into a bath of mercury contained in an annular channel e within the casing a.
The bell d is fixed to the stem f of a double-beat valve g g and is loaded with
weights h for regulating the outflow pressure of the gas. The stem f is con-
nected by a link i at its upper end with a shackle k attached to a regulating
screw turning in a nut mounted in the cover m and operated by a hand wheel n.
When the screw is in the lowest position the valves g will be removed from their
seats and give passage to the gas, in which position the bell floats and is free
to rise and fall under variations of pressure, the links ik allowing freedom of
vertical movement sufficient in extent to allow the valve to pass from the closed
to the full open position. By raising screw 7 by means of hand wheel until
the valve is closed as shewn in Figure 1 the bell d which is also raised will be
rendered immovable and the flow of gas to the main will be shut off.
It is to be understood that the forms, dimensions, details and materials em-
ployed in the construction of the apparatus may be varied without in any way
departing from the principle of the invention.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
1 claim is
The herein described combined pressure regulator and stop valve for gas mains
consisting in the combination with a floating bell chamber and double-beat
valve mounted within a casing having inlet and outlet orifices, of the means
described for enabling the bell and valve to be raised for cutting off the supply
and lowered to give passage to the gas and permit of the regulation of the pres-
sure, substantially as specified.
