PROVISIONAL SPECIFICATION.
Improvements in Gas Regulators.
We, WOLF DEFRIES of 4 Danes Inn London in the County of Middlesex,
Gentleman, and VICTOR ISIDORE FEENY of 60 Queen Victoria Street in the
City and County of London, Consulting Engineer, do hereby declare the nature of
this invention to be as follows:-
The object of our invention is to provide a sensitive gas regulator in which a full.
way is provided for the passage of the gas at any desired pressure.
For this purpose we make the outlet pipe of the same diameter as the inlet and
extend it into a valve chamber formed at the bottom of the regulator closing the
inner end of such extension.
Upon this extension we make the valve seat or seats, the total area of which is.
equal to that of the bore of the inlet or outlet.
We may use a single valve or an equilibrium valve of any suitable construction
and we may make the extension having the valve seat or seats in one piece
with the outlet pipe or it may be separate from it and suitably attached to some
other part of the regulator care being taken to preserve the arrangement above
described.
The valve or valves are carried by a stem attached to a float contained within
an annular chamber above the valve or valves which at its lower end communi-
cates with an outer annular chamber, such chambers containing water or any
suitable liquid or liquids, preferably water, with a layer of oil on top.
Into this outer chamber a tube from the outlet rises above the level of the liquid,
and the pressure of the gas conveyed through this tube tends to depress the liquid
in the outer chamber thereby raising the liquid in the inner chamber and tending to
raise the float.
By adjusting the weight of the float with suitable weights the pressure necessary
to raise the float can be varied at will, and for instance by weighting the float so
that it just touches the bottom of the chamber when no pressure is on, the addition
of another weight placed on the top of it will cause it to require a definite
minimum pressure before it will rise; when that pressure is attained the float at
once begins to rise and carrying with it the valve or valves contracts the passage for
the gas from inlet to outlet.

COMPLETE SPECIFICATION.
Improvements in Gas Regulators.
We WOLF DEFRIES of 4 Dane's Inn London in the County of Middlesex
Gentleman and VICTOR ISIDORE FEENY of 60 Queen Victoria Street in the City
and County of London Consulting 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 our invention is to provide a sensitive gas regulator in which a full
way is provided for the passage of the gas at any desired pressure.
Upon reference to the accompanying drawings illustrating our invention and on
which
Figure 1, represents a vertical section through a regulator.

page_text: Figure 2, a sectional plan through line 1-2 and
Figure 3, a sectional plan, through line 3-4
It will be seen that we make the outlet pipe B of the same diameter as the
inlet A and extend it into a valve chamber C formed at the bottom of the regulator
closing the inner end of such extension..
Upon this extension we make the valve seat or seats D, the total area of which is
equal to that of the bore of the inlet or outlet.
We may use a single valve as shewn at E or an equilibrium valve of any
suitable construction; in the case of a single valve we form one or more grooves F
in the face of the valve or on the valve seat D, and we may make the extension
having the valve seat or seats in one piece with the outlet pipe or it may be separate
from it and suitably attached to some other part of the regulator, care being taken to
preserve the arrangement above described.
The valve or valves E are carried by a stem G attached to a float H contained
within a cylindrical chamber I above the valve or valves which at its lower end
communicates with an outer annular chamber K, such chambers containing water
or any suitable liquid or liquids L, preferably water with a layer of oil on top.
Into this outer chamber K a tube. M from the outlet B rises above the level of
the liquid, and the pressure of the gas conveyed through this tube tends to depress
the liquid in the outer chamber K.thereby raising the liquid in the inner chamber
and tending to raise the float H.
By adjusting the weight of the float with suitable weights N the pressure
necessary to raise the float H can be varied at will, and for instance, by weighting
the float so that it just touches the bottom of the chamber when no pressure is on,
the addition of another weight placed on the top of it will cause it to require a
definite minimum pressure before it will rise; when that pressure is attained the
float at once begins to rise and carrying with it the valve or valves contracts the
passage D for the gas from inlet A to outlet B.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
2
A gas regulator, constructed, combined and arranged substantially as described
and illustrated upon the accompanying sheet of drawings.
