Improvements in Dry Governors for Regulating the Pressure
of Gas.
I WILLIAM LYON of 161, Pye Bank Sheffield in the County of York 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 :-
This Invention relates to a further or extended application of the principle of
the Invention described in the Specification of the Letters Patent granted to me
on the 27th day of March 1882 N° 1472, and also to a modification of such
Invention where such extended application or modification are desired.
The first named Patent, as and being for an improved Governor for regulating
the pressure of Gas claimed for such an arrangement of parts as should cause the
pressure of the outlet gas to act on the surface of a liquid contained in a closed
Compartment, such Compartment opening at or near its base into a second Compart-
ment of the Governor, whereby the liquid in the second Compartment, actuated as
before mentioned, should by its rise and fall, raise or lower a float therein, connected
with and governing the general inlet valve, and opening or shutting the same as
required.
The object of the present Invention, is to attain a like result relating to the
pressure of Gas as before mentioned, but in a modified form of Governor, that is,
without the use or employment of any liquid, and to supply, in fact, for Gas
Consumers, an improved kind of Governor of the class called or known as
Governors."

To effect my object, I make the Governor of a Bell shape with the diaphragm
or top moveable part, made of leather, or other like substance as usually employed
Through the centre of this diaphragm, a rod (with a small flange) is inserted,
reaching to the point at which the gas enters into the Consumer's pipe, and at such
point of the rod, a Valve or other simple contrivance is attached so as to close or
open the outlet.
Between such outlet and the inner side of the diaphragm, a spiral spring
is placed, encircling the Rod before mentioned, and above such diaphragm, and
encircling the rod protuding from the top of same, are placed weights, so as to act
upon the Spring, and which, according to the extent of weight employed, compress

outlet, and the action of the Governor is to some extent automatic.
The gas supply inlet from the main, may be through the side or bottom of the
Governor, as may be found most convenient.
The accompanying Drawings illustrate the features of my Invention.
Figure 1 shews the Governor when the outlet pipe is closed by the raising of
the Valve and the outlet pressure off.
Figure 2 shews the same when the Consumer's pipe is open and the outlet pressure
acting on the Consumer's fittings.
Figure 3 is an outside elevation.
Like letters of reference where such letters appear indicate corresponding parts
in the Drawings.
In Figure 1 the Valve A as attached to the Rod B is operated upon when
required by the Spring C and Weights G, and when thereby raised to the point D,
being the outlet of the Consumer's supply Tube E, shuts off the Glas, the tube F
being the supply tube from the Main, and in any event, the whole of the Gas
consumed is drawn directly from or through the Governor.
In Figure 2, the Spring C is shewn as compressed to the lowering of the Valve
and Rod B, by means of the weights G, the pipe I (as plugged) being the one
which may in some cases, if desired, be used as the inlet from the Main instead of
the pipe F.
In Figure 3, a Cap H, is shewn as used to cover the top part of the rod and
weights thereon, to protect the same.
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
In connection with a diaphragm and Rod through same, and weights thereon,
as usually employed, for regulating the flow and pressure of Gas, an improved
and simple method of effecting the object, by the use or addition of a Spiral Spring,
acted upon, underneath the Diaphragm, and acting as a balance of same by means
of the weights as shewn.
