IMPROVEMENTS IN GAS REGULATORS FOR SUPPLYING GAS TO GAS MOTORS
Year: 1885

page_text: I HENRY NIELD BICKERTON of Richmond Street Ashton-under-Lyne in the
County of Lancaster, Engineer, do hereby declare the nature of my invention of
IMPROVEMENTS IN GAS REGULATORS FOR SUPPLYING GAS TO GAS MOTORS" to
be as follows:-
:
.
The object of this invention is to construct a gas regulator capable of supplying
the necessary gas to a Gas Motor; uniformly, and without interfering with the
pressure in the main and thus to prevent any oscillation or jumping of the gas
lights supplied from the same main.
In performing my invention I employ a small vessel-similar to any ordinary
gas regulator with an inlet and an outlet passage for the Gas.
This vessel is connected to the supply pipe leading from the main to the Cas
bag and is covered by preference by a diaphragm of sufficient pliability to rise
slightly by the pressure of the gas. The gas as it flows to the gas bag is in full
and free communication with the under side of this diaphragm which rises and
falls with the varying pressure in the bag. Attached to or suspended from the
diaphragm in any convenient manner is a truncated shaped valve which is so
mounted in its seating that when it rises with the diaphragm it gradually contracts
the inlet to the diaphragm chamber and conversely by its fall enlarges the same.
A dome shaped cover encloses the diaphragm and completes the vessel. A com-
munication between the atmosphere and the inside of this dome is necessary and
this I prefer to make in the following or any similar manner. To the dome
I attach a hollow upright stem in which I make a small lateral hole for the
gradual admission of air at the top of this hollow stem I apply a mushroom or
check valve opening outwards and which allows the air to pass outwards or in one
direction only. In this manner I construct a gas regulator which requires no
adjustment as there are no levers or other mechanical contrivances and which
permits the valve to close rapidly and to open gradually. Instead of the
diaphragm being covered as aforesaid I sometimes connect the spindle by means of
a rack and pinion to a revolving vane and thus I prevent the too rapid fall of the
diaphragm and consequent opening of the valve or I connect the valve spindle to
a piston fitting loosely in a vessel containing any suitable liquid for the same
purpose.

I HENRY NIELD BICKERTON of Richmond Street, Ashton under Lyne in the
County of Lancaster, Engineer, do hereby declare the nature of my 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 this invention is to construct a gas regulator capable of supplying
the necessary gas to a gas Motor uniformly and without interfering with the
pressure in the main and thus to prevent any oscillation or jumping of the gas
lights supplied from the same main.
On the accompanying drawing Fig. 1. represents a sectional view of a Gas
regulator for Gas motors embracing my improvements.
In performing my invention I employ a vessel a similar to any ordinary gas
regulator with an inlet b and an outlet passage c for the gas. This vessel a is
connected to the supply pipe leading from the main to the gas bag and is covered
by preference by a diaphragm d of pliable leather or other suitable material of
sufficient pliability to rise slightly by the pressure of the gas. The gas as it flows
to the gas bag is in full and free communication with the under side of this
diaphragm which rises and falls with the varying pressure in the bag. Attached
to or suspended from the diaphragm & in any convenient manner is a truncated-
shaped valve e which is so mounted in its seating that when it rises with the
diaphragm dit gradually contracts the inlet of to the diaphragm chamber f¹ and
conversely by its fall enlarges the same. A dome shaped cover g encloses the
diaphragm and completes the vessel. A communication between the atmosphere
and the inside of the dome is necessary and this I prefer to make in the following
or any similar manner. To the dome g I attach a hollow upright stem h in which
I make a small lateral hole i for the gradual admission of air. At the top of this
hollow stem h I sometimes supply a mushroom or check valve j opening outwards
and which allows the air to pass outwards or in one direction only.
In this manner I construct a gas regulator which requires no adjustment as
there are no levers or other mechanical contrivances and which permits the valve
to close rapidly and to open gradually. . Instead of the diaphragm being covered as
aforesaid I sometimes connect the spindle as illustrated in modification Fig. 2. by
means of a rack and pinion m to a revolving vane n and thus I prevent the too
rapid fall of the diaphragm d and consequent opening of the valve e or I connect
the lower extremity of the valve spindle to a piston o as illustrated in modification
Fig. 3, such piston o fitting loosely in a vessel p containing any suitable liquid for
the same purpose.

If the diaphragm q and vessel r be considerably enlarged as illustrated in Fig. 4.
then the peculiar truncated shape of the valvo a alone will be sufficient to prevent
fluctuation in the gas main without employing any means of controlling its motion
and in this case the regulator may be used as the gas bag thus dispensing with the
ordinary gas bag usually applied to gas engines.

page_text: Having thus particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what
I claim is :-
1st In the construction of gas regulators for gas motor engines, the employment
of a truncated-shaped valve in conjunction with the means of controlling its
motion, substantially as and for the purposes hereinbefore described and illustrated
on the accompanying drawing.
2nd The improved construction and arrangement of gas regulator controlled by a
truncated-shaped valve capable of being used in addition to or instead of the
ordinary gas bag substantially as and for the purposes hereinbefore described and
illustrated on the accompanying drawing.
