Improvements in Incandescence Gas Lighting.
I, ERNST SALZENBERG, of No. 1, Mariannenstrasse, Crefeld, in the German
Empire, Manager of Gas and Water Works, do hereby declare the nature of this
invention to be as follows:-
The present invention relates to the production of incandescence gas light
and is based upon the discovery that when the pressure of the gas is considerably
increased upon the incandescence body the said body emits a golden yellow light
very agreeable to the eye and which light displays objects in their natural colours.
Hitherto it has however been impossible to make use of greater pressure of
gas than the usual one because of the great sensitiveness of the incandescence
Body and because the suspended incandescence body is broken up by high gas
pressure and in consequence of its light weight is blown away from the burner.
The applicant has discovered that yellow light and a great intensity of lighting
can be obtained by means of a considerably increased gas pressure on condition
that the incandescence body is made use of in such manner as to render it possible
to withstand the high gas pressure without breaking up and being blown away.
In accordance with the present invention the gas is supplied to the burner
at a pressure of about three atmospheres or upwards, and in order to render this
possible the incandescence body is attached to the burner by means of incom-
bustible fastenings in such a manner that the same is capable of withstanding
the pressure. By this means a single incandescence jet of the usual size can
evolve a light of up to one thousand candles. On application of the extremely
high gas pressure pointed flames are evolved when a single mantle is used which
flames pass out between the meshes of the mantle. This drawback can be
avoided by drawing several mantles in the unburned state over one another and
then incinerating the whole. Or a single mantle constructed of several layers
of fabric may be employed. The pointed flames formed on the innermost mantle
layers then impinge against the threads of the outer layers or mantles and are
thereby broken up and prevented from passing through.
The accompanying drawing shows a section through a method of fastening the
incandescence body applicable for the carrying out of this process.
The mantles a a¹ and so forth are placed one upon another in the unburned
condition and incombustible threads of asbestos, platinum or the like, passed
through, and after the combustion of the mantles the threads are so secured
around the outermost layer of incandescence material as well as secured to the
burner or burner support, that the incandescence body is enclosed within a netting
of incombustible threads or wires and cannot be blown off or destroyed by means
of the high gas pressure.

page_text: The mantle support c. which in consequence of the great development of heat
may be easily burned away is preferably protected by means of a. cover. d of
incombustible material such for instance as asbestos, platinum, fire clay, pipe
clay or the like. For the purpose of creating the gas pressure any suitable
pressure apparatus may be made use of.
Improvements in Incandescence Gas Lighting.
I, ERNST SALZENBERG, of No. 1, Mariannenstrasse, Crefeld, in the German
Empire, Manager of Gas and Water Works, 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:-
The present invention relates to the production of incandescence gas light
and is based upon the discovery that when the pressure of the gas is considerably
increased upon the incandescence body the said body emits a golden yellow light
very agreeable to the eye and which light displays objects in their natural colours.
Hitherto it has however been impossible to make use of greater pressure of
gas than the usual one because of the great sensitiveness of the incandescence
body and because the suspended incandescence body is broken up by high gas
pressure and in consequence of its light weight is blown away from the burner.
The applicant has discovered that yellow light and. a great intensity of lighting
can be obtained by means of a considerably increased gas pressure on condition
that the incandescence body is made use of in such manner as to render it possible
to withstand the high gas pressure without breaking up and being blown away.
In accordance with the present invention the gas is supplied to the burner
at a pressure of about three atmospheres or upwards, and in order to render this
possible the incandescence body is attached to the burner by means of incom-
bustible fastenings in such a manner that the same is capable of withstanding
the pressure. By this means a single incandescence jet of the usual size can
evolve a light of up to one thousand candles. On application of the extremely
high gas pressure pointed flames are evolved when a single mantle is used which
flames pass out between the meshes of the mantle. This drawback can be
avoided by drawing several mantles in the unburned state over one another and
then incinerating the whole. Or a single mantle constructed of several layers
of fabric may be employed. The pointed flames formed on the innermost mantle
layers then impinge against the threads of the outer layers or mantles and are
thereby broken up and prevented from passing through.
The drawing filed with the Provisional shows a section through a method of
fastening the incandescence body applicable for the carrying out of this process.
The mantles a a¹ and so forth are placed one upon another in the unburned
condition and incombustible threads 6 of asbestos, platinum or the like passed
through and after the combustion of the mantles the threads are so secured
around the outermost layer of incandescence material as well as secured to the
burner or burner support, that the incandescence body is enclosed with a netting
of incombustible threads or wires and cannot be blown off or destroyed by means
of the high gas pressure.

may be easily burned away is preferably protected by means of a cover d of
incombustible material such for instance as asbestos, platinum, fire clay, pipe
clay or the like. For the purpose of creating the gas pressure any suitable
pressure apparatus may be made use of.
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. The improved method for the production of an incandescence gas light
characterized by the supply of the gas to the incandescence body at a pressure
at which a light of golden yellow colour is caused.
2. A modification of the process set forth in Claim 1, characterised by the
supply of the gas to the suitably secured incandescence body at a higher pressure
than could be resisted by the weight of the freely suspended incandescence body.
3. A further modification of the process according to Claim 1, characterised
by the delivery of the gas to the correspondingly strengthened incandescence
body at a higher pressure than that corresponding to the resistance of which
the normal incandescence mantle would be capable by its own strength.
4. In the process set forth in Claims 1 to 4 the use of a number of mantles
drawn in the unburned condition over one another and incinerated together,
or of a fabric composed of several layers of material for the purpose of preventing
sharp flames passing through the same on the application of a high gas pressure.
