page_text: I GEORGE SMITH of 5 Rockley Road, West Kensington Park in the County of
Middlesex, Gas Engineer do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide a regulator for regulating the supply
of gas between the meter and burners whereby the gas is allowed to pass into the
regulator before going to the burner, so that gas under low pressure is supplied to
the burners no matter what the pressure at the main may be.
The regulator is composed of a reservoir or body for the gas having an inlet
on one side and an outlet on the other; in the reservoir or body I provide a
diaphragm the upper surface of which is connected to a spindle which goes up into
the regulator cap which spindle may be weighted if found necessary. The lower.
surface of the diaphragm is by slings connected to a disc or eccentric which is itself
carried by a bracket secured to the base of the body of the regulator; in the disc
there is a quadrant shaped slot in which a pin on a horizontal shaft works, this
shaft goes through bearings in standards secured to the base of the body and the
outer end of the shaft carries a valve which has its seating on the inlet.
Where this regulator is applied to a holder having water or mercurial seal the
spindle passes through the holder and tank and rises and falls with the bell which
then acts as the diaphragm.
The pressure of gas on the valve opens same and admits gas to the body of the
regulator, when the latter is full the pressure on each side of valve is equal; the
eccentric disc rotating as the diaphragm ascends the valve is closed and the supply
of gas cut off until the consumption at the burners makes a fresh supply from the
inlet necessary.

page_text: I, GEORGE SMITH of 5 Rockley Road West Kensington Park in the County of
Middlesex 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:-
The object of my Invention is to provide a regulator for regulating the supply
of gas between the meter and burners whereby the gas is allowed to pass into the
regulator before going to the burners so that gas is supplied to the burners under
low pressure no matter what the pressure at the main may be.
Fig. 1 of the accompanying drawing is a vertical section through a regulator
constructed according to this Invention, and fig. 2 a detail view.
The regulator is composed of a reservoir or body A for the gas having an inlet B
on one side and an outlet C on the other. In this reservoir or body I provide a
diaphragm D the upper surface of which is connected to a spindle E which goes up
into the regulator lid A¹ and cap F which spindle may be loaded with a weight G
if found necessary. A light helical spring H may suitably be placed between the
diaphragm and the lid A¹. The lower surface of the diaphragm D is by rod or
links I connected to a disc or eccentric K which is itself carried by a più L in a
bracket M secured to the base of the body A of the regulator. In this disc K
there is a quadrant shaped slot K¹ in which a pin N on a horizontal rod or shaft
works. This shaft O goes through bearings in standards P secured to the base of
the body A and the outer end of the rod O carries a valve Q which has its seating
on the inlet B. In Figure 2 I have shewn another and lighter form of the part K.
Where this regulator is applied to a holder having water or mercurial seat, the
spindle E passes through the holder and tank and rises and falls with the bell
which acts as the diaphragm.
The pressure of gas on the valve Q opens and admits gas to the body A of the
regulator and when the latter is full the pressure on each side of the valve is
equal; the eccentric disc or part K rotating on its fulcrum pin L in the direction
of the arrow a as the diaphragm D ascends in the direction of the arrow b the
valve is closed in the direction of the arrow d and the supply of gas cut off,
until the consumption at the burners makes a fresh supply from the inlet necessary.
Having now particularly described and ascertained the nature of this Inven-
tion and in what manner the same is to be performed I declare that what
I claim is
A Gas regulator having a flexible diaphragm which is so connected to a disc or
part K that the inlet valve Q which by pin and radial slot is connected to the
part K tends to close when the diaphragm is raised by excess of the normal gas
pressure, and vice versâ tends to open when the pressure decreases, substantially
as described and shewn.
