We, WILLIAM THOMAS SUGG and DAVID WILLIAM SUGG, both of Vincent Works
Vincent Street in the City of Westminster, Gas Engineers do hereby declare the
nature of this invention to be as follows:-
It is well known that with regenerative burners it is of the greatest importance to
maintain uniformity of consumption under the varying pressures of gas in the mains
and the variations in the quality of the gas to both of which these burners are so
highly sensitive.
Hitherto it has been necessary in order to regulate the supply of gas to these
burners to disconnect the fittings and consequently to put out the light.
Now the object of this invention is to obviate these conditions and to enable the
consumer to adjust the light to its proper consumption according to the quality of gas
existing in his district, without taking apart any of the fittings, or extinguishing the
light, which may remain burning while he is adjusting the flame to its
proper diinen-
sions and the invention consists in the means for adjusting the consumption of the
gas according to the variations of the quality and maintaining a uniform supply of gas
under any variation of pressure.
In carrying out our invention we employ a governor or governors of the diaphragm
or disc type which as usually constructed fail to efficiently regulate the supply of gas
to the burner; for example the governor is regulated to supply a given amount of gas
but should the gas be lowered during absence from the apartment (by turning off the
supply) to a small bead of gas and the pressure on the main increase from any cause
this bead will be increased to a considerable extent and a waste of gas will thereby take
place. The cause of this increase is that by shutting off the supply of gas the governor
is thrown out of action and so long as the maximum supply is not attained it will
continue out of action and therefore no regulation can take place, but by our improve-
ment we are enabled to ensure that the supply shall be uniform whatever may be the
pressure of the gas.

page_text: The governor we form with an outlet passage from under the diaphragm or disc of
such dimensions as to pass any desired maximum supply of gas and in this passage we
place a tap plug or regulating screw by means of which the size of the outlet may be
regulated to pass any quantity (large or small) of gas within the maximum without the
least variation in the supply as the governor will always remain in action the full
supply of gas being always admitted thereto.
When a tap or plug is employed we make it with two ways or passages and we
prefer to pass the gas through it, to the governor as well as to the burner, one of the
gas ways serving as the inlet to, and the other the outlet from the governor.
These passages or ways will be arranged to let in a full supply so long as any
portion of the outlet is open thus the governor will always be in action but the supply
to the burner will be regulated by the size of the outlet from the governor.
The governors may be arranged singly or in pairs, the latter form is preferred for
districts where the pressure in the main is normally more than two inches.
In the double governor the first diaphragm is weighted to give one inch on the.
outlet and the 2nd diaphragm is weighted to give an excess of gas on the outlet and
the quantity required to produce a flame of the full size adjusted by the screw; or
when a tap is used by turning it until the flame is seen to be of the full size.
The gas passes from one governor to the other through a suitable passage formed on
the governor support.

Gas Burners.
We WILLIAM THOMAS SUGG and DAVID WILLIAM SUGG both of Vincent Works
Vincent Street in the City of Westminster Gas Engineers 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 :--
It is well known that with regenerative and inverted burners it is of the greatest
importance to maintain uniformity of consumption under the varying pressures of
gas in the mains and with the variations in the quality of the gas to both of which
these burners are so highly sensitive.
Hitherto it has been necessary in order to readjust the supply of gas to these
burners to disconnect the fittings and consequently to put out the light if the gas is
burning, such re-adjustment being necessary if the quality of the gas is different from
that with which the governor was originally adjusted.
Now the object of this invention is to obviate these conditions and to enable the
consumer to adjust the light to its proper consumption according to the quality of gas
in his district without taking apart the fittings and to regulate the flow without
extinguishing the light which may remain burning while he is adjusting the flame to
its proper dimensions, and the invention consists in the means for adjusting the
consumption of the gas according to the variations of the quality and maintaining a
uniform supply of gas under usual variations of pressure such means being indepen-
dent of those parts acted upon direct by the gas as will be hereafter fully explained.
In carrying out our invention we employ a governor or governors of the diaphragm,
dise or other type having a communication with the external air above the disc which
governors as usually constructed fail to efficiently regulate the supply of gas to the
Burner if the gas not of uniform quality. For example the governor is regulated
to pass a given volume of gas per hour, of a given quality, and should the gas supplied
be of a higher quality than that with which it was originally adjusted, it is necessary
to check the flow of gas by the gas tap but such means of adjustment throws the
governor out of action so that with an increase of pressure after such adjustment the
flame becomes too large and smokes, and so long as the maximum supply for which
the governor is adjusted is not attained it will continue out of action and therefore no
regulation can take place. By our improvements we regulate the delivery of the gas
from the governor so that the supply to the governor is always full on, and thus the
governor will always remain in action whatever may be the quantity of gas being
actually delivered to the burner.
In the accompanying drawing Figs. 1 and 2 are sectional elevations of the simplest
form of single governor taken at right angles the one to the other.

page_text: Figs. 3 and 4 show in sectional elevation and sectional plan a single governor
combined with a special plug as will be hereafter more fully referred to and
Figs. 5 and 6 are respectively a longitudinal sectional elevation and a front elevation
partly in section of a double governor.
A is a casting which forms the body of the governor and in which are formed
certain recesses and passages and the lower end of the casting is closed by the
cup piece A¹ which is formed with a stem A* to screw into the burner pipe, said stem
having a central gas way of any suitable diameter. The body is also formed with a
projection on one side, A2, as seen in Fig. 1 and in this projection gas ways are formed.
B is the diaphragm to the centre of which is secured in any well known manner the
valve stem and valve which closes the inlet to the governor. The gas enters the
governor body by the arm which also serves as the means for carrying the lamp to
which the governor is secured.
In Figs. 3 and 4 the body is formed with a barrel to receive a plug of a cock as will
be hereafter referred to.
The gas then enters by the pipe C and passes by the passage 1 to the central
chamber 2.
The upper end of this chamber is provided with a valve seat of any suitable con-
struction for the valve attached to the diaphragm. From the chamber 2 the gas
passes through the valve to the diaphragm chamber 3. From this chamber the gas
passes by the passage 4 to the chamber 5 and thence to the burner.
In the passage 4 a screw down valve or other suitable shutting off or adjusting
arrangemont D is placed and by raising or lowering this valve the passage 4 will be
more or less contracted or opened. By this means the supply of gas to the burner
can be regulated to a nicety and will always remain so regulated notwithstanding any
increase of pressure in the main, for the governor is always open to the main and will
therefore always be in action to lessen or increase the supply up to the maximum as
may be required.
Instead of the screw D in the passage 4 we may adapt a bye pass tap or cock
below the stem A*, the gas way formed in the plug of such tap or cock, being of such
dimensions as will pass the maximum quantity of gas required for the particular
burner to which the governor is adapted, but arranged so as not to shut the gas off
entirely, leaving a small flame burning which will be controlled by the governor.
It will be understood that in both the above arrangements a tap or cock will be
placed on the inlet to completely shut off the gas when required.
In the arrangement shown in Figs. 3 and 4 the plug E takes the place of the
adjusting screw D. This plug is formed with two ways 6 and 7 the way 6 serves to
permit of the gas passing from the supply pipe C to the chamber 3 and the way 7
forms a continuation of the passage 4 from the chamber 3 to the chamber 5 and to the
burner. The way 7 is of small diameter and the way 6 is of such a size and is so
arranged that there shall always be a full supply of gas to the governor so long as any
part of the way 7 is open.
In the arrangement shown at Figs. 5 and 6 a similar plug is shewn but there are
two governors. This form is preferred for districts where the pressure in the main is
normally more than two inches.
Thus the first diaphragm will be weighted to give one inch on the outlet and the
second diaphragm will be weighted to give an excess of gas on the outlet and the
quantity required to produce a flame of full size as adjusted by a screw down valve
as before mentioned or by turning the tap or cock as before explained.
In the Figures the course of the gas will be from the plug through passage 1 to the
1st governor thence by the passage 2 to the 2nd governor passing by the passage 3 in
which a screw down valve may be placed (in addition to the plug) and the secondary
passage in the plug to the burner.
When the governor is placed above the light and near the ceiling we prefer to adapt
to the plug a small pulley E* to which a cord or chain may be secured by the centre
of its length. The free ends of this cord or chain will be of sufficient length to
enable the consummer to work the plug in order to regulate the flow of gas from the

page_text: governor to the burner and they will be provided with different shaped knobs or
pendents marked with the words " onl " and "off."
