PROVISIONAL SPECIFICATION.
Improvements in or connected with Incandescent Gas Lamps.
I, HERMANN WINKLER, of 97, Dresdener Strasse, Berlin, in the German
Empire, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in or connected with incandescent gas
lamps.
In the employment of intense incandescent gas burners, which are fed with
air under pressure, the necessity frequently arises that the said burners, which
give a very bright light, should be employed for obtaining a less intense light
with a less gas consumption and without the employment of air under pressure.
Now, this invention has for its object to provide means whereby this can be
effected. Furthermore, the jet of highly compressed air which streams out from
the nozzle possesses peculiar properties, the employment of which also form the
subject of the invention.
In such lamps the air under pressure is usually conveyed through a cock a
regulating screw and a small pipe to the nozzle. The pressure air passes also
through a lateral passage into a chamber where it operates upon the underside
of a diaphragm. The gas enters through passages into the said chamber above
the diaphragm whence it can pass through a valve to a nozzle.
In order now to allow gas instead of air under pressure to pass into the small
pipe and nozzle air cocks are utilized the said cocks being provided for this
purpose; by turning these cocks the entrance of the air under pressure to the
nozzle can be interrupted and a passage is opened to the small pipe for the gases
flowing from the gas chamber.
To prevent compressed air and gas simultaneously flowing to the apparatus I
provide suitable means such as lever mechanism whereby one cock is closed
when the other opens communication between the gas chamber and the small
inlet pipe.
The two nozzles are also advantageously arranged concentrically. Through
the inner nozzle, which supplies the air under pressure and which is furnished
with small perforations, a relatively small quantity of highly compressed air is
fed, the said air having by reason of its degree of compression a high velocity so
that the strong jets of air, which flow through the small perforations, suck up
not only the gas flowing from below but also the air flowing through orifices
into the burner tube, the said gas and air being carried away with the
compressed air. This result has never before been attained in an incandescent
gas burner.

I, HERMANN WINKLER, of 97, Dresdener Strasse, Berlin, in the German
Empire, 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 or connected with incandescent gas
lamps.
In the employment of intense incandescent gas burners, which are fed with
air under pressure, the necessity frequently arises that the said burners, which
give a very bright light, should be employed for obtaining a less intense light
with a less gas consumption and without the employment of air under pressure.
Now, this invention has for its object to provide means whereby this can be
effected. Furthermore, the jet of highly compressed air which streams out from
the nozzle possesses peculiar properties, the employment of which also forms the
subject of the invention.
In such lamps the air under pressure is usually conveyed through a cock, a
regulating screw and a small pipe to the nozzle. The pressure air passes also
through a lateral passage into a chamber where it operates upon the underside
of a diaphragm. The gas enters through passages into the said chamber above
the diaphragm whence it can pass through a valve to a nozzle.
In order now to allow gas instead of air under pressure to pass into the small
pipe and nozzle air cocks are utilized the said cocks being provided for this
purpose; by turning these cocks the entrance of the air under pressure to the
nozzle can be interrupted and a passage is opened to the small pipe for the gases
flowing from the gas chamber.
To prevent compressed air and gas simultaneously flowing to the apparatus I
provide suitable means such as lever mechanism whereby one cock is closed
when the other opens communication between the gas chamber and the small
inlet pipe.
The two nozzles are also advantageously arranged concentrically. Through
the inner nozzle, which supplies the air under pressure and which is furnished
with small perforations, a relatively small quantity of highly compressed air is
fed, the said air having by reason of its degree of compression a high velocity so
that the strong jets of air, which flow through the small perforations, suck up
not only the gas flowing from below but also the air flowing through orifices
into the burner tube, the said gas and air being carried away with the
compressed air. This result has never before been attained in an incandescent
gas burner.
To enable the invention to be fully understood I will describe it by reference to
the accompanying drawing, in which:-
Figure 1 is a vertical section of an incandescent gas lamp having the control-
ling device fitted to the igniter :
Figure 2 is a plan view of the lower portion shewing the parts necessary for
illustrating the arrangement for supplying the gas from the gas chamber to the
air nozzle.
Figure 3 is a side view corresponding to the plan view, and
Figures 4 and 5 shew in side elevation and plan respectively the link and
lever mechanism of the controlling device.
In the arrangement shewn the compressed air flows through the purifier a,
the small tube b and the cock c. After it has passed the latter it flows through
the lateral passage into the air chamber e where by pressure upon the dia-
phragm fit raises the gas valve g as it overcomes the tension of the spring h.

page_text: The compressed air cannot pass out of the chamber e but merely holds the gas
valve g open. The air also passes by the regulating screw and through the
cock and the tube k and flows to the nozzle 7, when the parts are in the normal
position. The gas in this case flows through the supply pipe m and the passage n
into the gas chamber o and thence passes through the valve g, the holes, and
the annular space q to the nozzle . The air and gas meet in the space r between
the nozzles and . The gas is sucked up by the stream of compressed air and
a quite peculiar mixture of air and gas is obtained which when burned in
connection with the incandescent mantle gives rise to a very intense light.
In the arrangement here shewn, as distinguished from nozzles as heretofore
usually made, the two nozzles and are arranged concentrically as above
described. Through the inner nozzle 7, which is provided with very small
perforations, there flows a relatively small quantity of air, the said air being
highly compressed and having a high velocity so that the powerful jets of air
issuing from its small perforations not only draw up the gas supplied from the
space but also the air which passes into the burner tube through the open-
ings s, s¹. This result has never before been obtained in incandescent gas lamps.
When now for any reason a less powerful illumination instead of the full
intense light is desired, the burner is supplied with gas only, the said gas itself
drawing in the air which it requires for its combustion. This gas, however, does
not pass through the valve g to the nozzle in the manner above described as the
said nozzle has too large an opening and would not produce the necessary jet of
gas.
For this reason, therefore, the gas is caused to flow from the gas chamber o
to the nozzle 1. The connection is effected through the pipe t (Figures 2 and 3)
one end of which is fitted to a nipple o' upon the cover o2 of the gas chamber o
and the other end of which opens into the three-way cock which, according to its
position, cuts off the gas coming from the chamber o or allows it to flow through
so that in the latter case the gas can pass to the pipe and nozzle 7.
In order, however, to prevent compressed air and gas simultaneously flowing
through the pipe and nozzle 7 the cocks c and j are so connected together that
the air cock c is closed when the cock opens communication between the gas
chamber o and the tube and vice versa, that is to say, the connection being
broken when compressed air is passed through the cock c. This control of the
cocks is effected by the levers and fitted to the plugs of the cocks c and j
respectively. A link w connects these two levers in such a manner that one cock
cannot be moved independently of the other.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
-
1. In incandescent gas lamps of the kind described the arrangement consisting
of the two cocks and the tube connecting the gas chamber with the upper cock,
in combination with the mechanism for controlling the said cocks, substantially
as and for the purpose herein before described.
2. In incandescent gas lamps of the kind described the concentric arrangement
of two nozzles the inner of which is provided with fine perforations and is supplied
with compressed air which draws gas and atmospheric air into the burner pipe,
substantially as hereinbefore described.
3. An incandescent gas burner constructed substantially as hereinbefore
described and illustrated in the accompanying drawing.
