hereby declare the nature of this invention to be as follows:-
:-
To effect my object I make the Governor of cylindrical or any suitable form
attached to which is a moveable Top, this constitutes the outside case. Through the
bottom of this case 1 attach two vertical tubes an inlet & an outlet. The inlet pipe
is made up at the top by a solid cap projecting over the circumference of tube &
forming a fixed valve face, underneath this face around the circumference of the tube
are cut V or any other suitable apertures so as to enable the Gas to flow into the
inner case of the Float hereafter described.
The Float I make of two cylindrical cases a larger & a smaller, the smaller going
inside the larger & fastened together at the bottom forming a hollow cylindrical
float. In the centre of this float is fixed by means of cross legs or stays with the
inner cascing of the tube large enough to encase the fixed inlet tube and of allowing
the float & tube (which makes other face of valve) to work freely. This tube working
up or down with the float makes in conjunction with the cap of fixed inlet tube
a valve which is sealed by the liquid in the body of the case.
To put the Governor in working order remove the loose cover & pour in the outer
case of Governor, liquid until the Hoat with the outer tube rises bringing the two faces
of the valve together, thus stopping the flow of Gas to the consumers pipes. Weights
are now placed on the top of the float to rate it to the required pressure of the user.
It will now be seen that the pressure of Gas in the inlet chamber of float causes the
valve to close & open automatically according to the requirements of the user.
Dated this 28th day of October 1887.

Improvements in Wet Governors for Regulating the Flow of Gas.
FRANK WOOD 38 Arundel Street Sheffield in the County of York, Manufacturer
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 refers to Improvements in Station, District, Consumers & other 5
Governors for regulating the Pressure of Gas so that for example although the
pressure of supply may be equal to 40/10th inches of water displacement the pressure
on the outlet will be automatically governed & gas supplied at the undeviating
pressure of 10/10th inches, however much the consumption varies.
My invention consists in governing the inlet gas valve automatically by the
pressure of Gas in the inlet pipe acting on the surface of a fluid contained in the
Governor, thereby raising or lowering the float connected directly with the said inlet
valve.
I accomplish the above end by constructing my Governor as follows & with a view
to an easy definition I shall refer to the accompanying section by means of letters.
The Governor may be made of cylindrical or any suitable shape, with a moveable
lid or top to outside case. Through the bottom of this outside case I fix two vertical. "
tubes one the inlet pipe in the centre of case, the other the outlet nearer the
circumference.
Around the circumference of the inlet pipe at the top I cut acute V or any other
suitably shaped spaces & make up the top of tube by screwing a cap to it & allowing
it to project over the circumference of tube forming in conjunction with the floating.
tube (which I shall now. describe) a valve.
The Float I make of the same shape as outside Case, with a watertight chamber to
make it buoyant. In the centre of this float fixed in a vertical position by means
of stays or cross legs with the inner side of watertight chamber, is a tube large
enough to work freely over the vertical inlet pipe before described. The Float when
rising bringing with it the outer tube & covering the apertures under cap of inner
tube thus regulating the flow of Gas to Consumer.
'
To put the Governor in working order I pour water or any suitable liquid in the
outer case until the float rises & closes the valve, weights are now placed on the
float which may be rated to the consumers requirements.
It will now be seen that the Gas enters the inlet pipe A, flowing through the
apertures into chamber of float B and thence through the outlet pipe C to the
consumers pipes. The pressure of Gas in chamber of Float B acting on surface of
liquid D causing the float to rise and automatically open or shut the apertures
on inner tube.

page_text: 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
An improved valve & float arrangement dispensing entirely with a vertical rod used
for carrying the valve. My valve being constructed of two tubes, moving one inside the
other, one being perforated the other being entact, thereby opening or closing the
apertures.
Any valve for regulating the flow of Gas substantially as described & as illustrated
on the annexed sheets or any mere modification of the same.
