Lancaster, Gas Engineer, and John Barrow, of West Gorton, near
Manchester, in the same County, Manufacturing Ohemist, for the
Invention of "IMPROVEMENTS IN EFFECTING THE IGNITION OF GAS, AND
APPARATUS AND MEANS FOR OPENING THE SUPPLY OF GAS TO BURNERS, FOR
IGNITING THE GAS. AND FOR EXTINGUISHING GAS LIGHTS.”
Sealed the 17th February 1874, and dated the 2nd September 1878.
PROVISIONAL SPECIFICATION left by the said Henry Green and John
Barrow at the Office of the Commissioners of Patents, with their
Petition, on the 2nd September 1878.
We, HENRY GREEN, of Preston, in the County of Lancaster, Gas
Engineer, and JOHN BARROW, of West Gorton, near Manchester, in the
same County, Manufacturing Chemist, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN EFFECTING THE IGNITION OF Gas,
AND APPARATUS AND MEANS FOR OPENING THE SUPPLY OF GAS TO BURNERS, FOR
IGNITING THE GAS, AND FOR EXTINGUISHING GAS LIGHTS," to be as follows:-
.
This Invention is designed to furnish practicable and reliable means
of enabling gas to be readily turned on and ignited, and the light to be

page_text: afterwards extinguished, as may be required, at any burner or at a
number of burners or places simultaneously, and has reference chiefly
to apparatus actuated by gas pressure.
According to the first part of our Invention we apply to each lamp or
burner a small collapsible vessel or chamber, connected to and arranged
to actuate a suitable lever or tumbler carrying a cup or vessel of mercury
or other suitable sealing liquid, arranged to effect the opening and
closing as required of a nozzle or orifice for supplying or conducting gas
to the burner; and in order to obviate the difficulties arising from the
variations in pressure usual in gas mains we so construct or regulate
this collapsible vessel that it shall not expand or open out until subjected
to a higher pressure than the maximum ordinary pressure in the mains,
but that when the pressure is increased so as to expand or open out the
collapsible vessel it shall actuate the lever or tumbler in such manner as
to unseal the nozzle or orifice communicating with the burner, at the
same time actuating suitable apparatus for effecting the ignition of the
gas, as herein-after described, after which the gas pressure may be
reduced, whereupon the collapsible vessel or chamber collapses, or its
moving part (or parts) falls or moves inwards, but by a suitable
mechanical device we cause it (or them) to be arrested at the proper
time and to be retained and securely held in the proper position for
keeping open the nozzle or orifice leading to the burner, so that gas may
continue to flow through to the burner until the extra pressure is again
put on, whereupon the collapsible vessel or its moving part or parts is or
are again expanded or caused to move outward, and in so doing acts or
act upon our aforesaid mechanical device, so that when the extra
pressure is again taken off the holder is left free to collapse or close up
so that its lever or tumbler shall cause the nozzle or orifice leading to
the burner to be sealed or closed, thereby extinguishing the light.
Our Invention further consists in effecting the ignition of the gas by
bringing together through the operation of the gas pressure, or other-
wise, suitable chemicals, which by their action on meeting shall produce
the requisite flame or spontaneously inflammable gas for igniting the
gas.
The chemical agents employed may be brought together in a suitable
uniting chamber or vessel situated near the burner so as to produce a
temporary flame when requisite, and thereby to ignite the gas issuing
from the burner.

page_text: One of the chemical agents or mixtures employed may be in the form
of a liquid, and may be contained in the uniting chamber, and another
chemical agent or mixture may be in the form of pills or little balls.
A number of such pills or balls may be stored in a suitable pipe,
receptacle, or vessel having a nozzle or orifice provided with suitable
apparatus connected to the collapsible vessel so as to be actuated by its
movements in such manner as to allow one pill or ball at a time to drop
or pass when requisite into the liquid contained in the uniting chamber
for the purpose of generating the necessary flame or spontaneously
inflammable gas, as above explained.
In some cases the cup or vessel of mercury or other sealing liquid,
actuated as herein-before described, may be arranged to effect the
opening and closing as required of two nozzles or orifices, one supplying
or conducting gas to the burner, and the other supplying or conducting
gas to a separate orifice or orifices provided with a uniting chamber for
igniting the gas by chemical means, thereby producing at the said orifice
or orifices a separate gas flame for effecting the ignition of the gas
issuing from the main burner. In this arrangement both of the nozzles
or orifices in the collapsible vessel are kept unsealed during the lighting
operation, after which on the closing of the orifice leading to the
igniting apparatus the further collapse or moving inwards of the
collapsible vessel or its moveable part or parts will be prevented by our
aforesaid mechanical device, which will keep open the nozzle or orifice
leading to the burner until the extra pressure is again put on and taken
off, as already explained, whereupon the collapsible vessel will close or
collapse so as to seal the nozzle or orifice leading to the burner as well
as the nozzle or orifice leading to the lighting apparatus.
Our apparatus for governing the opening and closing of the orifice or
orifices for the gas, as well as the parts of our Invention which relate to
effecting the ignition by chemical agents, besides being used in con-
junction with each other, may respectively be used in some cases apart
from each other in connexion with other arrangements or apparatus for
effecting the opening of the gas supply, the ignition of gas, and the
extinction of gas lights.

filed by the said Henry Green and John Barrow in the Great Seal
Patent Office on the 2nd March 1874.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
GREEN, of Preston, in the County of Lancaster, Gas Engineer, and JOHN
BARROW, of West Gorton, near Manchester, in the same County, Manu-

nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date
of the said Letters Patent.
"
NOW KNOW YE, that I, the said Henry Green, for myself and on
behalf of the said John Barrow, do hereby declare the nature of the said
Invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement
thereof, and the Drawings therein referred to (that is to say) :-
This Invention is designed to furnish practicable and reliable means
of enabling gas to be readily turned on and ignited, and the light to be

page_text: afterwards extinguished, as may be required, at any burner or at a
number of burners or places simultaneously or nearly so, and has
reference chiefly to apparatus actuated by gas pressure.
According to the first part of our Invention we apply to each lamp or
burner a small collapsible vessel or chamber connected to and arranged
to actuate a suitable lever or tumbler carrying a cup or vessel of mercury
or sealing liquid arranged to effect the opening and closing as required
of a nozzle or orifice for supplying or conducting gas to the burner,
and in order to obviate the difficulties arising from the variations in
pressure usual in gas mains we so construct or regulate this collapsible
vessel that it shall not expand or open out until subjected to a higher
pressure than the maximum ordinary working pressure in the mains,
but that when the pressure is increased so as to expand or open out the
collapsible vessel it shall actuate the lever or tumbler in such manner as
to unseal the nozzle or orifice communicating with the burner, at the
same time actuating suitable apparatus for effecting the ignition of the
gas, as herein-after described, after which the gas pressure may be
reduced, whereupon the collapsible vessel or chamber collapses, or its
moving part (or parts) falls or moves inwards; but by a suitable
mechanical device we cause it or them to be arrested at the proper
time, and to be retained and securely held in the proper position for
keeping open the nozzle or orifice leading to the burner, so that gas may
continue to flow through to the burner until the extra pressure is again
put on, whereupon the collapsible vessel or its moving part or parts is or
are again expanded or caused to move outward, and in so doing acts or
act upon our aforesaid mechanical device, so that when the extra
pressure is again taken off the holder is left free to collapse or close up,
so that its lever or tumbler shall cause the nozzle or orifice leading to
the burner to be sealed or closed, thereby extinguishing the light.
Our Invention further consists in effecting the ignition of the gas by
bringing together through the operation of the gas pressure or otherwise
suitable chemicals which by their action or meeting shall produce the
requisite flame or spontaneously inflammable gas for igniting the gas.
The chemical agents employed are brought together in a suitable
3 uniting chamber or vessel situated near the burner, so as to produce a
temporary flame when requisite, and thereby to ignite the gas issuing
from the husnes

page_text: One of the chemical agents employed is in the form of a liquid
contained in the uniting chamber, and another chemical agent or
mixture is in the form of pills or little balls. A number of such pills or
balls are stored in a suitable pipe, receptacle, or vessel having a nozzle
or orifice provided with suitable apparatus connected to the collapsible
vessel, so as to be actuated by its movements in such manner as to allow
one pill or ball at a time to drop or pass when requisite into the liquid
contained in the uniting chamber for the purpose of generating the
necessary flame or spontaneously inflammable gas, as above explained.
In some cases the cup or vessel of mercury or sealing liquid actuated
as herein-before described, may be arranged to effect the opening
and closing as required of two nozzles or orifices, one supplying or
conducting gas to the burner, and the other supplying or conducting
gas to a separate orifice or orifices provided with a uniting chamber for
igniting the gas by chemical means, thereby producing at the said orifice
or orifices a separate gas flame for effecting the ignition of the gas
issuing from the main burner. In this arrangement both of the nozzles
or orifices in the collapsible vessel are kept unsealed during the lighting
operation, after which on the closing of the orifice leading to the igniting
apparatus the further collapse or moving inwards of the collapsible
vessel or its moveable part or parts will be prevented by our aforesaid
mechanical device, which will keep open the nozzle or orifices leading to
the burner until the extra pressure is again put on and taken off, as
already explained, whereupon the collapsible vessel will close or collapse
so as to seal the nozzle or orifice leading to the burner, as also the nozzle
or orifice leading to the lighting apparatus.
Our apparatus for governing the opening and closing of the orifice or
orifices for the gas, as well as the parts of our Invention, which relate to
effecting the ignition by chemical agents, besides being used in con-
junction with each other may respectively be used in some cases apart
from each other in connexion with other arrangements or apparatus for
effecting the opening of the gas supply, the ignition of gas, and the
extinction of gas lights.
Such being the nature of our said Invention, we now proceed to
describe the manner of performing the same, reference being had to the
accompanying Sheets of Drawings, and the figures and letters marked
thereon. The same letters of reference are used to denote equivalent
parts in each of the several views.

page_text: Fig. 1 is a side elevation partly in section of an apparatus according
to our Invention; Fig. 2 is a side elevation at right angles to the
foregoing; Fig. 3 is a plan view of the base plate and other portions
partly in section; Fig. 4 is a vertical section in the line A, B, of Fig. 3,
with the flexible connecting piece or band removed; and Figs. 5 shew in
elevation at right angles to Fig. 1 parts of the device for keeping the
collapsible vessel expanded.
a is the burner, to which gas is conducted by a pipe 6 communicating
with a nozzle o, terminating within a collapsible vessel or chamber d
composed of a base plate & and a crown plate d³ (hinged at d'), joined
together by a flexible connecting piece or band a³, which may be of
leather, so as to make the chamber d perfectly air-tight. The crown
plate d³ is weighted by flat pieces of lead or other convenient means, so
as to very slightly exceed the maximum working pressure of the gas in
the mains. Within the chamber d is a lever or tumbler e having its
fulcrum at e¹, and slotted at one end e³ to allow of the free passage
within certain limits of a pin or stud attached at its upper end to the
crown plate d³ of the collapsible vessel, and formed or provided at its
lower end with a head or projection f¹ for lifting the end of the lever or
tumbler e when the collapsible vessel d is expanded or opened out by gas
entering from the supply pipe g.
When the collapsible vessel d is collapsed or closed, the slotted end e¹
of the lever e is depressed by its own weight, thereby sealing the nozzle
or orifice c by means of mercury contained in a cup or vessel h carried
by the other end of the lever or tumbler, but when the collapsible vessel
is expanded by the gas pressure the slotted end of the lever being raised
depresses the cup of mercury, thereby unsealing the nozzle or orifice o
and permitting gas to flow to the burner. Mercury is supplied to the
eup & through the pipe h².
We cause the crown plate d³as already explained to just overcome
the maximum ordinary pressure of gas in the mains, in connexion with
which our Invention is applied, so that when the gas supply is to be
either turned on to the burner and ignited or cut off and extinguished,
the gas pressure in the mains is to be for a few seconds augmented
5 slightly beyond the ordinary maximum pressure, which augmentation
is effected by means of a regulator or governor at the works, as well
understood,

page_text: The collapsible vessel is caused to remain in a partially expanded
position by a mechanical device consisting of a grooved wheel or cam
carried by a small bracket on the crown plate d³, and having its axis
at . This wheel or cam is formed with two notches *, **, and provided
with four pins k, k¹, k³, k³, or cross pieces traversing the groove in its
periphery, which pins or cross pieces operate in conjunction with a
pawl working on a pin P. Attached to the base plate d¹ of the
collapsible vessel is an adjustable pin or projection m operating in con-
junction with the wheel or cam i, into one or other of whose notches³, **,
this pin m enters when the collapsible vessel d is collapsed or closed.
In Fig. 1 the collapsible vessel is shewn in this position with the pin or
projection m in the notch. On now expanding the vessel the cross
pin / of the wheel or cam i will enter the bent of the pawl 7, thereby
partially rotating the wheel or cam, so that on the gas pressure being
again reduced the descent of the crown plate d² will be arrested by the
pin or projection m coming into contact with the part of the periphery
of the wheel or cam i, which will keep the collapsible vessel partially
expanded, so that gas may continue to flow to the burner a until on its
being desired to shut off the gas from the burner the pressure is again
temporarily augmented byond the ordinary maximum pressure as before,
whereupon the wheel or cam i will by the action of the pawl as before
be again partially rotated until its notch is brought into position to
· receive the pin or projection m. On the extra pressure being now taken
off the crown plate & will descend so as to liberate the slotted end of the
lever or tumbler, whose cup or vessel will thereupon ascend and seal the
nozzle or orifice c. The wheel or cam i is prevented from being
accidentally turned back by a small catch P. To the crown plate d³ is
hinged or jointed a wire or rod n, cranked or provided with a loop at n³,
and bent like an elbow at n³. Through this wire or rod motion from the
crown plate d³ is communicated to the lever o, o¹, (whose fulcrum is at o³
in the bracket x) for uncovering the uniting chamber p which contains
the liquid chemical agent, and to the levers q, r, to regulate the feeding
one by one at the proper times from the pipe or receptacles through the
nozzle s¹ to the uniting chamber p of the pills or balls t, f, for generating
the necessary flame or spontaneously inflammable gas for igniting the
illuminating gas issuing from the burner.

page_text: pipe or receptacle s. Into another similar orifice enters a projection or
stopping pin ¹ carried by the lever r, which is bent at ³, and has its
fulcrum at . That arm of this lever carrying the stopping pin 7¹ is
made to preponderate over the other arm of the lever. The upper arm o¹
of the lever o, o¹, carries a stopper u made of vulcanized india-rubber,
ground glass, or other suitable material, so as to truly fit the face against
which it closes for excluding air from the chemical agent in the uniting
chamber p, when it is not required to be open. The parts being in the
relative positions shewn in Figs. 1 and 2, on the collapsible vessel d
being expanded as already described, the loop n' coming in contact with
the arm o will, through it and the arm o³, uncover the uniting chamber p,
whilst as the part n² of the wire rises and releases the part of the
lever r, the stopping pin will descend between the pills t, f, and by
the continued upward movement of the wire n, its part ³ coming in
contact with the part q³ of the lever q, will raise the stopping pin o̟³
partially out of the pipe or receptacle 8, thus allowing the pill t to
descend by the nozzle s¹ into the liquid chemical agent in the uniting
chamber p, and so by the action of the chemical agents thus brought
together generating the necessary temporary flame or spontaneously
inflammable gas to ignite the gas issuing from the burner a.
On now
removing the extra pressure the collapsible vessel d will partially collapse
sufficiently to close the uniting chamber p by its stopper, but not so as
to cause the actuation of the lever r, and as already explained, tho
collapsible vessel will be kept sufficiently expanded to allow of the con-
tinued flow of gas to the burner a until the pressure is again temporarily
augmented and subsequently reduced as previously described. This
last-mentioned reduction of pressure, besides cutting off and ex-
tinguishing the gas, will bring about the descent of the wire n, thereby
drawing down the part of the wire and raising the stopping pin r³,
so that the pill & may take the place of that shewn at t in Fig. 1, and
so on.
To the nurnace
cenerating the necessary flame or spontaneously

page_text: whereupon the collapsible vessel d will close or collapse, so as by the
change of positions of the crown plate d and lever or tumbler e to seal
the nozzle or orifice c, the nozzles c, c³, being then both sealed.
Fig. 9 is a side elevation partly in section; Fig. 10, a longitudinal
vertical section; Fig. 11, a transverse section; and Fig. 12, a plan view
illustrating an apparatus furnished with a hydraulic governor or trap,
shewn separately in the sectional views Figs. 13, 14, 15, and 16.
This apparatus is arranged so as to obviate the loading or weighting
of the crown plate d², which may be made very light so as to enable gas
of very low pressure to be used without difficulty, as well as to afford
increased available power for expanding the collapsible chamber and
actuating the mechanical parts in connexion with it. To this end for
opening or closing the gas supply to the burner a the pressure in the
main is temporarily increased, sufficiently to overcome the resistance of
a column of water or liquid in the trap before gaining admission to the
chamber d, which it consequently enters at a pressure exceeding the
resistance offered by the crown plate dº.
Gas from the main entering the apparatus by the pipe g flows into
the compartment w of the trap, wherein it presses against the surface w
) of the water or liquid, which is forced up into the compartments w³, w³,
until the surface w' is depressed below the top of the slot or orifice w³,
whereupon the level in w³ also falls below the top of the said slot
or orifice, and gas flows into the compartment w³, and by the
orifice w³ enters the collapsible chamber d, which is thereby opened out
5 or expanded, so that the weighted end e³ of the lever or tumbler e
previously held up by the stud d' is now left free to descend and raise
the partition h² of the cap h above the level of the mercury h* (fed in
at ), thus placing the nozzles or pipes c, c, in communication with
each other, so that gas entering by the pipe will flow through c, o, to
O the burner a. On the extra pressure being taken off, the surface of the
water or liquid in the compartments w, w³, will rise above the top of the
slot or orifice w³, and the gas remaining in the chamber d will escape
therefrom by the small orifice d*. wª is an adjustable overflow pipe
- screwed through the bottom of the trap. The raising or lowering this
5 pipe regulates the height of the column of water or liquid to be overcome
by the gas before it can enter the chamber d.

page_text: The arrangements for keeping the collapsible vessel partly expanded,
and for igniting the gas by chemical agents and extinguishing when
required, are the same as those in Figs. 1 to 5, inclusive.
Figs. 17, 18, and 19, shew our plan of arresting the crown plate ď³ to
retain the collapsible vessel partially expanded, and subsequently per-
mitting of its collapse as required, and our method of igniting the gas
by means of chemical agents as applied to apparatus in which the crown
plate ď³ is made to serve in lieu of the lever or tumbler e for carrying a
cap to operate in conjunction with mercury h* for sealing and
unsealing the nozzle c.
This arrangement will be readily understood from the Drawings
without further description, it being understood that when the nozzle c
is unsealed the gas flowing in by the pipe 9 passes through the chamber d,
nozzle c, and pipe 6, to the main burner.
Figs. 20, 21, and 22 shew the application of the said parts of our :
Invention to an apparatus wherein the crown plate d³ carries two caps
h, h', operating in conjunction with mercury, so that during the
temporary augmentation of the gas pressure beyond the maximum
ordinary working pressure both of the caps will be out of the mercury,
and the nozzle a leading to the main burner, as well as the nozzle o¹
leading to the messenger pipe v, will be open for the flow of gas,
substantially as herein-before explained with reference to the arrange-
ment shewn in Figs. 6, 7, and 8, but when the temporary extra pressure
is removed the crown plate d³ will fall so that the longer cap h' will dip
into the mercury and seal the nozzle c³, in which position the crown ;
plate d³ will be retained with the shorter cap h, still above the level of
the mercury, so that the nozzle c will remain open for the flow of gas to
the main burner until the extra pressure is again put on and taken off as
explained with reference to a previous arrangement, whereupon the
collapsible vessel will close or collapse, so that both caps will enter the 3
mercury and seal the two nozzles c, c². The form of the igniting
arrangements is slightly modified in a manner which is clearly shewn in
the Drawings, and therefore needs no further description.
It will be obvious that in carrying out our Invention the wheel or
cam i may be attached to the base plate of the collapsible vessel, the
pawl and adjusting pin m, or its equivalent being attached to and
carried by the crown plate d², and that the crown plate, instead of being

page_text: hinged may be made to work in guides, but we prefer to hinge it to
ensure perfect working of the wheel i.
"
Our method of igniting gas by the use of chemical agents may be
advantageously employed in connection with lamps or burners to which
the supply of gas is regulated by taps or cocks in the ordinary way. In
such cases we arrange a uniting chamber p in juxtaposition to each
burner, as shewn in Fig. 1, but there being no collapsible vessel we
connect the lower end of the wire n to one arm of a bell-crank lever
working on a fixed stud or pin in the ordinary way and provided with a
spring to retain it normally in such position as to keep the wire n in its
lowest position, from which it is raised as required for operating the
cover # and pill feeding levers by pulling a wire attached to the other
arm of the bell-crank lever in a manner that will be readily understood
without further description.
Having described the nature of our said Invention for "Improvements
in Effecting the Ignition of Gas, and Apparatus and Means for Opening
the Supply of Gas to Burners, for Igniting the Gas, and for Extinguishing
Gas Lights," and having explained the manner of carrying the same
into practical effect, we hereby declare what we consider to be novel and
original, and therefore claim under the Letters Patent herein-before in
part recited to be,-
First. The construction of apparatus for opening the supply of gas
to burners, igniting the gas, and extinguishing the lights by temporary
augmentations of the gas pressure, substantially as shewn in and
described with reference to Figs. 1, 2, 3, 4, and 5 of the Drawings.
Secondly. The construction of apparatus shewn in and described with
reference to Figs. 6, 7, and 8 of the Drawings.
Thirdly. The use or employment in connection with a collapsible
vessel or chamber of a lever or tumbler arranged to effect the opening
and closing as required of a nozzle or orifice whereby gas flows to the
burner, substantially as described.
Fourthly. The arranging the collapsible vessel or chamber to expand
or open out only when subjected to a pressure exceeding the ordinary
maximum working pressure in the mains, and governing the action of
such collapsible vessel or chamber so that notwithstanding any variation
in pressure that may occur within the ordinary working limits, a constant

page_text: flow of gas to the burners is maintained until on the gas pressure being
temporarily augmented beyond the ordinary maximum working pressure
and subsequently reduced, the position of the holding device is changed,
leaving the collapsible vessel or chamber free to collapse or close up,
and thereby cutting off the gas supply, substantially as herein-before
described.
Fifthly. The above described method of effecting the ignition of the
gas by the use or employment of chemical agents, and the bringing
together of such chemical agents in a uniting chamber or vessel
arranged in juxtaposition to the gas burner or orifice or orifices so as to
produce a temporary flame or flames in the manner set forth.
In witness whereof, I, the said Henry Green, have hereunto set my
hand and seal, this Twenty-fourth day of February, in the year
of our Lord One thousand eight hundred and seventy-four.
