Improvements in Gas Governors.
JOSEPH WINTERFLOOD 133 Hemingford Road Barnsbury N. London Metal
Worker do hereby declare the nature of this invention to be as follows:-
My invention relates to an apparatus employed to regulate excessive pressure
down to a fixed maximum. In well known forms of such apparatus bell floats are
used, and, it is to such forms that my improvements relate:-In practice it is found
essential to employ double beat valves for the purpose of checking the gas in its
passage to the burners. My improvements consist in employing a single beat valve
so constructed that the bottom end dips into a mercury dish thus obtaining the
neutrality of the valve. To fill the dish with mercury I connect a tube from the
outer case of the governor to the edge of the dish. On one side of the governor I
form au inlet for the unregulated gas, and, on the opposite side an outlet for the
regulated gas to pass to the burners.

COMPLETE SPECIFICATION.
Improvements in Gas Governors.
I JOSEPH WINTERFLOOD of 133 Hemingford Road Barnsbury N. in the
County of Middlesex, Metal Worker 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 relates to an apparatus employed to regulate excessive pressure
down to a fixed maximum. In well known forms of such apparatus bell floats are
used and it is to such forms that my improvements relate. In practice it is found
essential to employ double beat valves for the purpose of checking the gas in its
passage to the burners.
My improvements consist in employing a single beat valve so constructed that
the bottom end dips into a mercury dish thus obtaining the neutrality of the valve.
On one side of the governor I form an inlet for the unregulated gas and on the
opposite side an outlet for the regulated gas to pass to the burners. This invention
has reference to those gas pressure regulators in which the pressure of the gas is
regulated by a stem or valve depending from a moveable float operating in or
against the gas inlet orifice.
Heretofore the bell float has been constructed like an inverted cup or basin
dipping into a mercury dish and the said stem or valve has been exposed to the
pressure of the unregulated gas, which being variable caused the float and the
pressure of the gas at the outlet of the regulator to fluctuate which defect it is
the object of this invention to overcome.
According to my invention I prevent the unregulated gas acting upon the base
of the stem or valve by a cup sealing. The bell float I construct like an inverted
cup with an extending flange and rim and in order that my invention may be more
fully understood I will now proceed to describe the same by the drawings hereunto

Like letters of reference indicate corresponding parts in the different figures of
the drawings.
A. is the body proper.
G. the regulating weights.
H. the cap for protection of the regulating weights.
From experience I find it makes no practical difference in using mercury for
the valve sealing and therefore I prefer to employ my improved valve without
mercury.
It will readily be seen that the gas in passing through the valve can have prac-
tically no disturbing effect upon it and the bell float with its extended flange as it
rises out of the mercury presents a larger surface to the pressure of the gas to
compensate for the increased weight of the float as it becomes less buoyant in
leaving the mercury.
I make no claim for any invention in respect of the mercury dish or bell float
shown in this Specification.
.
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 :-
:
First The apparatus for regulating or controlling the

drawings.

drawings, a valve with its cup sealing, to operate without mercury as herein
described and illustrated.
