PROVISIONAL SPECIFICATION.
An Improved Gas Governor.
I, FRANK STEPHEN STREETER, of 44, Amhurst Road, Hackney, in the County of
Middlesex, Gas Engineer, do hereby declare the nature of this invention to be as
follows: :-
My Invention relates to an improved gas governor for regulating the pressure
of gas to burners; and it is specially designed for controlling the gas supplied
through a descending tube to a number of burners although it is with slight
modification applicable for use in other cases. The governor proper consists of a
float-valve working up and down within an upright tube fluted or corrugated
longitudinally with fintings of tapering form, their cross-sectional area being greatest
at the lower end of the tube. The minimum internal diameter of the tube measured
at the ribs or spaces between the flutes or grooves is constant throughout the length
of the tube so that the valve which is of circular form and corresponding diameter
may move freely up and down within, and be guided by, the tube whilst leaving a
passage for the gas equal to the cross-sectional area of the flutes or grooves at the
point where the valve is for the time being situated.
The valve floats upon the column of gas, rising and falling as the pressure fluctuates
so as, in conjunction with the tapering form of the flutes, to vary the area of the gas
passage inversely to the variations of pressure. The valve is preferably composed of
two discs fixed upon a common stem at a sufficient distance apart to afford the
necessary lateral support and guidance, the stem serving also as a stop to limit the
motion of the valve. The fluted tube is enclosed within an outer tube which, in
the case of a descending column, is connected directly by its upper end with the
supply pipe and is closed at its lower end. The fluted tube is open at its lower end
to the outer tube and communicates at its closed upper end with lateral outlets leading
through the sides of the outer tube and opening into an external bulb or casing to
which the arms carrying the burners are connected.

COMPLETE SPECIFICATION.
An Improved Gas Governor.
I, FRANK STEPHEN STREETER, of 44, Amhurst Road, Hacknoy, in the County of
Middlesex, 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 :--
My Invention relates to an improved gas governor for regulating the pressure of
gas to burners; and it is specially designed for controlling the gas supplied through
a descending tube to a number of burners although it is with slight modification
applicable for use in other cases.
Reference is to be had to the accompanying drawings forming part of this specifica-
tion, wherein figure 1 is a central vertical section of the governor fixed on the central
bulb of a gaselier from which the arms radiate. Figure 2 is an underside view of
the corrugated tube of the governor. Figure 3 is a vertical section of the governor
in a plane at right angles to that of figure 1. Figure 4 is a section on line 1-1
DQ11

page_text: figure 3. Figure 5 shews the governor applied to an ordinary single burner. The
same letters of reference indicate like parts in all the figures.
The governor proper consists of a float valve a working up and down within an
upright tube & fluted or corrugated longitudinally with flutings 61 of tapering form,
their cross-sectional area being greatest at the lower end of the tube and gradually
diminishing to zero in the upward direction. The minimum internal diameter of the
tube 6 measured at the ribs or spaces between the flutes or grooves 61. is constant
throughout the length of the tube b so that the valve, which is of circular form and
corresponding diameter, may move freely up and down within, and be guided by, the
the tube b whilst leaving passage for the gas equal to the aggregate cross-sectional
areas of the flutes or grooves at the point where the valve a is for the time being
situated. The valve a floats upon the column of gas, rising and falling as the pressure
fluctuates, so as, in conjunction with the tapering form of the flutes 6, to vary the
area of the gas passage inversely to the variations of pressure. The valve disc a is
fixed upon a common stem c and a second disc d is fixed on the same stem at a
sufficient distance above disc a to afford the necessary lateral support and guidance,
the stem c serving also as a stop to limit the downward motion of the valve. The
disc d may be perforated to give free passage to the gas if it is not intended to act
as a valve but it need not necessarily be perforated and may act as a valve in con-
junction with the disc a. Both discs a and d aro cupped or flanged so as to present
a smooth surface to contact with the fluted tube. The stem c is screw-threaded and
the discs screw thereon and may be adjusted at different distances apart according to
the desired capacity of the governor. The motion of the governor in the upward
direction is limited by the disc d abutting against the casting g.
The fluted tube is enclosed within an outer tube e which, in the case of a descending
column of gas, is connected directly by its upper end with the supply pipe. In
figure 1 this connection is through the four holes f in the casting 9 to which the
outer and inner tubes e and b are fixed, as shewn. The tube e is closed at its lower
end by a cap e¹. The fluted tube bis open at its lower end to the outer tube and
communicates at its upper end with lateral outlets leading through the casting g into
an external bulb or casing i to which the arms; carrying the burners are connected.
The course of the gas is clearly indicated by the arrows.
In figure 5 no outer tube is necessary as the gas is supplied from below, whereas
in the other figures the gas being supplied from above, the outer tube or some
equivalent means of reversing the direction of the gas is necessary as the governor
acting by gravity can only regulate an ascending current of gas. In figure 5 there-
fore, the internally corrugated or fluted governor chamber is simply a continuation of
the gas bracket and needs no special description.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what 1
claim is :
1. A gas governor consisting in the combination with a floating disc valve of a
longitudinally corrugated or fluted tubular chamber having internal flutes or grooves
tapering in the upward direction, the valve being guided by the part of the tube
between the flutes and regulating the flow of the gas, by determining the point at
which it can only pass through the grooves, substantially as specified.
2. The herein described gas governor consisting in the combination of the floating
valve and guiding discs a d on a common stem c with the longitudinally fluted
tube b having flutes tapering in the upward direction, as described, the discs
working within the fluted chamber and regulating the flow of gas, substantially as
specified.
3. The herein described gas governor for regulating the passage of gas from the
pendent tube to the branches of a gaselier, the said governor consisting in the com-
bination of the floating valve and guiding discs a d on a common stem c working

page_text: within a tubular chamber 6 having longitudinally fluted sides of tapering form in the
upward direction, and of an outer chamber e the latter communicating with the pendent
supply pipe and the fluted chamber with the branches of the gaselier, all substantially
as specified and illustrated in the drawings.
