A New Composition of Matter for Automatically Lighting Gas and
for other purposes.
We, STANISLAW ROSINSKI, Civil Engineer, of 95, Avenue de Versailles, Paris,
France, and Madame VEUVE E. DUCRUIX, nee Marie Marguerite Pierquin, of
104bis, Boulevard Exelmans, Paris, France, do hereby declare the nature of this
invention to be as follows:-
This invention relates to a product which possesses the property of being ren-
dered incandescent by the action of a jet of gas directed upon it, the incan-
descence being due to the condensation in its pores of a considerable proportion
of the gas, the heat thereby developed being sufficient to ignite the gas.
The product consists essentially of gelatinous alumina impregnated with
platinum chloride, the invention being particularly characterized by the employ-
ment as a support for the platinum salt of the gelatinous alumina which has
the property of possessing a very great power of condensation.
The new product is prepared by immersing gelatinous alumina in a solution
of platinum chloride, in the proportion of one gramme of platinum chloride to
four grammes of alcohol. The gelatinous alumina after having been steeped in
the platinum chloride solution is brought to a temperature of about 120° C.
Owing to its great power
the product thus obtained being then ready for use.
of condensation, this new product is capable of many uses, either alone or
applied in special apparatus.
This new composition, owing to the rapidity with which it can be rendered
incandescent under the action of a jet of gas, may be employed for the manu-
facture of gas lighters in the form of matches but capable of being used over
and over again. For this purpose the match stems are tipped with a small
quantity of the material and in order to light a gas jet therewith it is only
necessary to turn on the gas and to hold the composition head or tip of the
lighter in the jet of gas whereupon the composition will become incandescent
and develop a sufficient amount of heat to ignite the jet, the same lighter being
capable of use over and over again an indefinite number of times.
This improved composition is more especially intended to be applied to the
purpose of automatic gas lighting and it is described in another application
of even date herewith, in combination with special constructions of gas control-
ling devices but it may also replace with advantage the spongy platinum employed
in apparatus for purifying the air for hygienic purposes, owing to its great
power of.condensation for gases, and it is to be understood that the several uses
of the product above specified are cited merely as examples.

PROVISIONAL SPECIFICATION.
Improvements in or connected with Automatic Gas Lighting
Apparatus.
We, STANISLAW ROSINSKI (Civil Engineer), of 95, Avenue de Versailles, Paris,
France; and MADAME VEUVE E. DUCRUIX, neé MARIE MARGUERITE PIERQUIN, of 104bis,
Boulevard Exelmans, Paris, France, do hereby declare the nature of this invention
to be as follows:-
Our invention which is applicable to gas burners generally, relates to the
automatic lighting of gas by the mere act of turning on the gas to the burner,
and comprises the provision of a material capable of being rendered incandescent
by contact of the gas, of a branch passage for directing a current of gas on to
said material, and of means whereby the branch passage is closed automatically
on the ignition of the gas at the burner by the incandescent lighter.
The last mentioned part of the invention consists essentially in effecting the
automatic closure of the branch passage by the expansion of a fluid on any other
expansible body acting upon an elastic bulb or membrane in such manner as to
cause the latter, on the expansion of the fluid under the action of the heat of
the burner, to shut off the branch passage. This device consists essentially of
a tube having one end closed and the other open, but enclosed by an elastic cap
or bulb of indiarubber, the said tube containing mercury and a certain volume
of air which, under the action of the heat of the lighted burner, is caused to
dilate and so expand the elastic cap or bulb which is applied to act as a valve
to shut off the passage of the gas through the branch passage. On the gas
being turned off, the air and mercury cool and contract, the elastic membrane
resumes its original form, and the passage is unclosed in readiness for the turning
on of the tap of the burner.
The composition of material to be rendered incandescent by the jet of gas
consists essentially of gelatinous alumina impregnated with a solution of platinum
chloride, containing one gramme of platinum chloride to four grammes of alcohol.
Our invention is illustrated in the accompanying drawings as applied to various
known types of gas burners. Figures 1 to 5 shew it as applied to a batswing burner;
Figure being an elevation, Figure 2 a side view, Figure 3 a vertical section,
Figure 4 a plan view, and Figure 5 a horizontal section on line 1-2 Figure 1.
Figures 6, 7, and 8 shew front, side, and sectional views respectively of the apparatus
as applied to an ordinary gas burner. Figure 9 shews the applicant to an incandes-
cent gas burner. Figure 10 shews an elevation and Figure 11 an underside view
of the device applied to a Bengel burner. The same letters of reference indicate
the same parts in all the figures.

page_text: a is a metal block having a channel which communicates directly, or through a
tube, with the gas supply passage leading to the burner, and with a chamber c of
slightly larger diameter, from which leads a channel d terminating in an upwardly
directed nozzle d¹ by which the jet of gas admitted through b is directed on to the
pellet of material e capable of being rendered incandescent by the gas and preferably
composed of gelatinous alumina impregnated with platinum chloride by steeping
in a solution containing one gramme of platinum chloride to four grammes of alcohol
and then heating it to 120° C. The gelatinous alumina forms a support for the
platinum chloride and possesses great power of condensation and rapidly becomes
incandescent under the action of the gas directed upon it. The pellet e which should
be in proximity to the burner, is mounted on a support of screwed to the block a,
and in order to obtain a more extended incandescent surface, a cluster of platinum
wires e¹ extend down from the pellet e to the base of support. f.
The device by which the gas is shut off from the nozzle when the gas is lighted,
consists of a tube screwed into the chamber c. This tube is closed at its upper
end and its open lower end is enclosed by a bulb h of elastic material such as india-
rubber, and the tube is filled with mercury and a certain volume of air. When the
gas is lighted at the burner, the tube becomes heated, the contained mercury
becomes dilated, the bulb is expanded and closes the channel b.
To adapt the improved automatic lighter to a batswing burner, the nipple i is con-
nected to the gas inlet j by two or three tubes k, the channel b in this case branching
directly from the gas inlet j, as shewn in Figure 3, and the upper end of the mercury
tube g is rounded so as to conform to the shape of said nipple through which it
extends. The whole is enclosed in a casing open at its upper end. Batswing
burners may thus be provided with an automatic lighting device without altering
their general form and be screwed on to existing gas fittings like ordinary
burners.
The device shewn in Figures 6 to 8 is adapted for use on burners of all kinds and
dimensions. To enable the position of the pellet of incandescible material e to be
adjusted relatively to the burner, the block & is mounted upon a tube m connected
with channel b and is fitted to slide in another tube n branched upon a union piece o
screwing on to the gas supply pipe below the burner as shewn in Figure 9 which
illustrates the application of the device to an incandescent gas burner. The tube m
is clamped at any suitable height in tube n by any ordinary means. The device is
enclosed in a protective casing (as before.
Figures 10 and 11 shew the automatic lighting device as mounted upon a Bengel
burner. In this case the tube m screws into gas inlet j. The pellet of incandescible
material is shewn at e. Its composition is the same as above described.
It is to be understood that the invention comprises the use of the improved auto-
matic gas controlling apparatus described with any other material capable of being
rendered incandescent by the contact of the gas.
Our improved automatic lighting device presents the great advantage of compact-
ness and of being readily adaptable to existing fittings; it is also of very simple
construction and not liable to get out of order, thus ensuring an efficient action.

a is a metal block having a channel b which communicates directly, or through
tube, with the gas supply passage leading to the burner, and with a chamber c of
0 slightly larger diameter, from which leads a channel & terminating in an upwardly
directed nozzle d¹ by which the jet of gas admitted through b is directed on to the
pellet of material e capable of being rendered incandescent by the gas and preferably
composed of gelatinous alumina impregnated with platinum chloride by steeping in a
solution containing one gramme of platinum chloride to four grammes of alcohol and
5 then heating it to 120° C. The gelatinous alumina forms a support for the platinum
chloride and possesses great power of condensation and rapidly becomes incandescent
under the action of the gas directed upon it. The pellet e which should be in
proximity to the burner, is mounted on a support f screwed to the block a, and in
order to obtain a more extended incandescent surface, a cluster of platinum wires e¹

end and its open lower end is enclosed by a bulb h of elastic material such as india-
rubber, and the tube is filled with mercury and a certain volume of air. When the
55 gas is lighted at the burner, the tube g becomes heated, the contained mercury
becomes dilated, the bulb h is expanded and closes the channel b.

page_text: To adapt the improved automatic lighter to a batswing burner, the nipple i is con-
nected to the gas inlet by two or three tubes k, the channel b in this case branching
directly from the gas inlet j, as shewn in Figure 3, and the upper end of the mercury
tube g is rounded so as to conform to the shape of said nipple through which it
extends. The whole is enclosed in a casing open at its upper end. Batswing
burners may thus be provided with an automatic lighting device without altering
their general form and be screwed to existing gas fittings like ordinary
burners.
The device shewn in Figures 6 to 8 is adapted for use on burners of all kinds and
dimensions. To enable the position of the pellet of incandescible material e to be
adjusted relatively to the burner, the block a is mounted upon a tube m connected
with the channel b and is fitted to slide in another tube branched upon a union
pieces o screwing on to the gas supply pipe below the burner, as shewn in Figure 9 which
illustrates the application of the device to an incandescent gas burner. The tube m
is clamped at any suitable height in tube n by any ordinary means. The device is
enclosed in a protective casing (as before.
Figures 10 and 11 shew the automatic lighting device as mounted upon a Bengel
burner. In this case the tube m screws into gas inlet j. The pellet of incandescible
material is shewn at e. Its composition is the same as above described.
In order to prevent any emission of gas at the burner until after the pilot jet is
ignited and so avoid explosion or loss of gas, a valve is provided controlling the supply
to the main burner to be opened by the expansion by the mercury of the elastic bulb
under the action of the heat produced by the ignition of the pilot jet as herein before.
described. This improvement is illustrated in vertical section in Figures 12 and 13
of the drawings as applied to an incandescent gas burner, and a Bengel burner
respectively.
In Figure 12 the union piece o which screws on to the gas supply pipe below the
burner is provided with a seat for a conical valve 2 which when the gas is not
lighted remains upon its seat. The stem of said valve bears upon the end of a
lever q pivoted at and connected at its other end to a thrust rod 8 passing up
through the tubes n and m and acted on by the bulb before described, when the
latter becomes increased in volume by the dilatation of the mercury and of the air
contained in tube g. When the material e becomes incandescent under the
action of the jet of gas emitted at 1, the rise of temperature thus produced causes
the expansion of the mercury and air contained in tube g whereby, through the
medium of bulb h, the rods, and lever q, the valve p is raised so as to allow the gas
to pass direct to the main burner and he there ignited, the heat emitted by the main
burner still further expanding bulb h and thereby closing the bye-pass to the pilot
jet whilst keeping the main valve open. When the light is extinguished the valve p
returns to its seat either by its own gravity or by the action of a light spring.
Figure 13 shews the application of the same improvement to a Bengel gas burner.
In this case the elastic bulb h acts upon a tubular stem s¹ contained in a tubular
casing t through which the gas is supplied to the pilot jet as will be hereinafter
described. The casing is screwed into the part of the union piece which is
chambered or bored of two diameters so that when the gas is unlighted the small
orifices in stem s¹ open into the chamber t¹, so as to allow the gas to pass from s¹ to
the nozzle . When the gas is lighted at the main burner the tube s¹ being forced
downwards by the expansion of the elastic bulb h, the orifices x will be covered
by the casing and the supply of gas to the pilot jet cut off. Upon the lower
end of the stem s¹ is fixed a disc valve p which is seated against the lower end of the
body portion and controlling the passage of the gas through two channels v to the
chamber wo leading through passage y to the main burner. When the burner is not
lighted the valve p is held against its seat by a spring on stem s¹. The union
piece is screwed on to the gas supply pipe, and so long as the gas is not lighted, the
valye shuts off the supply of gas to the main burner but as soon as the gas supply
is turned on at the tap the gas passes up through tube s¹, orifices x, and chamber t¹,
to the pilot jet ¹. The gas impinging on the pellet e renders it incandescent, the

page_text: at causes the mercury and air contained in tube g to expand, and
as before, and to force downwards the stem s¹ and open the valve p to permit the
s to pass to the main burner. By the continued expansion under the heat of the
ain burner the stem s¹ is forced down so that the orifices are completely covered
hereupon the pilot jet is extinguished, the gas continuing to burn at the main
urner only. On turning off the gas at the tap the elastic bulb in resuming its
riginal dimensions ceases to bear on stem s¹, and valve p is again pressed against its
eat by its spring so as to cut off the supply of gas to the main burner.
The improvements which may be applied to batswing and all other kinds of
as burners present the great advantage of effecting the automatic lighting, without
OSS, of Igas and without risk of explosion.
It is to be understood that the invention comprises the use of the improved auto-
matic gas controlling apparatus described, with any other material capable of being
rendered incandescent by the contact of the gas.
Our improved automatic lighting device presents the great advantage of compact-
ness and of being readily adaptable to existing fittings; it is also of very simple
construction and not liable to get out of order, thus ensuring an efficient action.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we wish it to be understood
that we are aware of the Specifications of H. A. Kent No. 18,012 of 1895, J. M
Canellopoulos and H. O. Kratz-Boussac; No. 3316 of 1896, and H. Borchardt, No.
2288 of 1897, and we lay no claim to anything described and claimed therein, but we
declare that what we claim is :---
1. An automatic lighting device for gas burners, comprising a pilot nozzle
connected to the gas supply pipe for directing a small jet of gas on to a material
capable of being thereby rendered incandescent in combination with a device con-
sisting of a tube in proximity to the lighter closed at one end and provided at the
other end with an expansible bulb adapted to act by its expansion as a valve to
control the passage of gas to the pilot jet, the tube containing mercury and a certain
0 volume of air so that by the expansion thereof under the heat emitted from the
lighted burner the bulb will be expanded and the gas cut off from the ignition or pilot
jet as specified.
2. The herein described automatic gas lighter wherein the supply of gas to the
main burner is controlled by a valve adapted to permit the supply of gas to the mai
5 burner only after the ignition of the pilot jet, the said valve being combined with
the device whereby the supply of gas to the pilot jet is controlled so that the opening
of the said valve to supply gas to the main burner and the shutting off of the suppl
to the pilot jet will be effected by the dilation of the said device as specified.
3. The application of the herein described automatic gas lighting device to a
40 kinds of gas burners.
