AN IMPROVED AUTOMATIC GAS GOVERNOR to be as follows:
Year: 1885

page_text: I ALFRED KINNEAR of No 19 Camomile Street, in the city of London, Yarn
Merchant do hereby declare the nature of the said invention for "AN IMPROVED
AUTOMATIC GAS GOVERNOR to be as follows:-
"
This invention relates to the construction of an improved automatic gas governor
for governing the quantity of gas passing through it, whereby the gas is governed
at the inlet to the governor, which occupies a small space.
For this purpose I employ a bored cylinder having an inward flange at the base
thus leaving a smaller inlet than outlet. Inside the cylinder I place a disc or float ·
of metal or other suitable material capable of sliding up and down; this disc is so
arranged that it just allows a given quantity of gas to escape past it at a normal
pressure when it is resting on the flange; attached to the bottom of this disc is a
small pin which passes down through the inlet and on the end of which, a cone of
metal or other substance is placed capable of being moved up and down the pin at
will, for regulation. This cone is so placed that it allows a sufficient quantity of
gas to pass up through the inlet, when the disc is resting on the flange. At the
side of this cone a small bye-pass or escape hole is placed.
The action is as follows:-when the gas is at a normal pressure and the disc and
cone are adjusted to allow a given quantity of gas to pass, the disc rests on the
flange, but upon an increase in the pressure of the gas taking place the disc rises
automatically with the pressure and the cone being attached consequently rises and
shuts off the inlet in proportion to the increase of pressure, leaving only a normal
pressure still to pass the disc; should the pressure be excessive and the disc and
cone are buoyed entirely up, the gas passes through the small bye-pass or escape
hole, thus keeping up the normal pressure passing the disc.-Upon any decrease in
pressure taking place, the disc and cone fall by gravity thus opening the inlet in
proportion as the pressure decreases.

page_text: I ALFRED KINNEAR of 91 Finsbury Pavement in the city of London, Managing
Director of Kinnear's Patents Limited do hereby declare the nature of this inven-
tion 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 the construction of an improved automatic gas governor
for governing the quantity of gas passing through it, whereby the flow of gas is
governed at the inlet to the governor, the said governor occupying but little space.
For this purpose I employ a bored cylinder having an inward shoulder so as to
leave a smaller inlet than outlet. Inside the cylinder I place a disc or float of
metal or other suitable material. capable of sliding up and down; this disc is so
arranged that it just allows a given quantity of gas to escape past it at a normal
pressure when it is resting on the shoulder; attached to the bottom of this disc is
a small pin which passes down through the inlet and on the end of which a cone
of metal or other substance is placed capable of being moved up and down the pin
at will, for regulation. This cone is so placed that it allows a given quantity of
gas to pass up through the inlet, when the disc is resting on the shoulder. At the
side of this cone a small bye pass or escape hole or holes is or are placed.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1, is an
elevation, and figure 2, is a vertical section of an automatic gas governor con-
structed according to my invention. The said figures are drawn to an enlarged
scale and similar letters in the same represent similar parts.
a, is the cylinder and b, is the projecting shoulder inside the cylinder a; which
from the said shoulder downwards is formed conically as shewn at C, and is pro-
vided with a screw thread on its exterior to allow of it being fixed to a gas pipe;
by this means the lower or inlet end of the cylinder a, is made smaller than the
upper or outlet end; d, is the disc or float of metal or other suitable material
which can slide up and down in the cylinder a, above the conical part thereof; the
disc d, is provided with bye passes e, on its under side at its periphery and fits
loosely in the cylinder so as to allow a given quantity of gas to escape past it at a
normal pressure when it is resting on the shoulder b, in the position shewn in
figure 2, is the pin attached to the bottom of the disc d; the said pin passes
down through the inlet or cone c, and is screw-threaded as shewn; g, is the cone of
metal or other substance on the end of the pin f, and which can be moved up and
down thereon at will for the purpose of regulating the position of the cone g, in
the opening h, at the lower end of the cone c; as will be seen the cone 9, if properly
adjusted will allow a given quantity of gas to pass up through the inlet 1, when
the disc d, is resting on the flange b; i, i, are the small bye passes or escape holes
in the cone g; j, is an ordinary gas nib or burner fixed in the upper end of the
cylinder a.
The action is as follows; when the gas is at a normal pressure and the disc d,
and cone g, are adjusted to allow a given quantity of gas to pass through the

page_text: inlet h, and by the disc d, the said disc d, rests on the flange b, but upon an increase
in the pressure of the gas taking place the disc d, rises automatically with the
pressure from below and the cone g, being attached consequently rises also and
shuts off the inlet h, in proportion to the increase of pressure, leaving only a normal
pressure still to pass the disc d; should the pressure be excessive and the disc d,
and cone g, are buoyed entirely up, the gas passes through the small bye passes or
escape holes i, i, thus keeping up the normal pressure of the gas passing the disc.
Upon any decrease in pressure taking place, the disc d, and cone g, fall by gravity
thus opening the inlet, in proportion as the pressure decreases.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is:
The manufacture and use of the improved automatic gas governor hereinbefore
described and represented in the accompanying drawing.
