PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Regulating the Flow and Pressure
of Gas.
I, WILLIAM FOULIS, of 45 John Street, Glasgow, in the County of Lanark,
North Britain, Civil Engineer, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in apparatus for regulating the flow and
pressure of gas, and is a modification of or an addition to the apparatus described in
the Specification of my former Patent No. 3655 of 19th September 1876.
The present invention has for its object to provide more efficient means for
guiding the regulating cone or bell, inside the governor or case, whereby the
friction is reduced to a minimum and all tendency to jump or oscillate, when the
valve is nearly closed, is overcome.
Also by means of an improved shape of the valve seat, the ring and cone meet
with an equal curve and so ensure steadiness.
In carrying out my said invention I build the cone or bell upon a central spindle,
mounted true with the valve seat; the said spindle is provided or formed at its
lower end with a barrel or cylinder which fits easily on a piston fixed in or formed
on the bottom of the case.
As the cone or bell rises or falls some of the liquid (preferably glycerine) con-
tained in the case must get into or out of the barrel or cylinder on lower end of
spindle, and this it can only do by passing the piston or by passing through an
orifice made in the barrel or cylinder for the purpose.
The cone or bell is guided at its top end by means of narrow vertical bars or
guide rods mounted across the conical opening, and the valve seat is made of such a
shape that the ring or seat proper and the cone meet with an equal curve.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Regulating the Flow and Pressure
of Gas.
I, WILLIAM FOULIS of 45, John Street, Glasgow, in the County of Lanark,
North Britain, Civil 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 improvements in apparatus for regulating the flow and
pressure of gas, and is a modification of or an addition to the apparatus described in
the Specification of my former Patent No. 3655 of 19th September 1876.
The present invention has for its object to provide more efficient means for
guiding the regulating cone or bell inside the governor or case whereby the friction
is reduced to a minimum and all tendency to jump or oscillate, when the valve is
nearly closed is overcome.
Also by means of an improved shape of the valve seat, the ring and cone meet
with an equal curve and so ensure steadiness.
In carrying out my said invention, as illustrated in sectional elevation in the
accompanying drawing, I build the cone or bell A upon a central spindle B,
mounted true with the valve seat C. The said spindle B is provided or formed at
P

page_text: its lower end with a barrel or cylinder D, which fits easily on a piston or plunger E,
fixed in or formed on the bottom of the case F, and preferably provided with a non
corrosive metal covering e.
As the cone or bell A rises or falls, some of the liquid (preferably glycerine)
contained within the case F passes into or out of the barrel or cylinder D, which is
on the lower end of the spindle B, and this can only take place by the liquid
passing the piston or plunger E, or by passing through an orifice made in the said
barrel or cylinder D for the purpose.
The cone or bell A is guided at its top end by means of narrow vertical bars or
guide rods G, mounted across the conical opening of the bell A. The valve H on
the top end of the bell A, and also the ring or valve seat proper J, are made of an
equal curved shape, as shown in the drawings, as to ensure of the cone or valve H
and the seat J meeting with an equal curve, and thus regulate the said governor.
The whole apparatus thus forms a steady, sensitive, smooth and efficient working
gas governor, which has no tendency to jump or oscillate owing to the variations of
the inlet pressure, and so any sudden change of pressure taking place is prevented
as the rise and fall of the bell is slow and steady owing to the space inside the
barrel D requiring to be filled or emptied by the liquid according to the movement
of the bell.
Having now particularly described and ascertained the nature of my said inven-
tion and in what way the same is to be performed, I declare that what I
claim is :-
(1) The general arrangement, construction and combination of the various parts
constituting my improvements in apparatus for regulating the flow and pressure of
gas substantially as hereinbefore described and shown in the accompanying
drawings.
(2) In gas governors as described, the piston or plunger E, and barrel or
cylinder D, acting as a guide to keep the bell truly vertical and as a regulator to
prevent any sudden action taking place substantially as hereinbefore described and
shown in the accompanying drawings.
(3) In gas governors as described, the formation of the valve H and valve seat J,
substantially as and for the purposes hereinbefore described and shown in the
accompanying drawings.
