PROVISIONAL SPECIFICATION.
Lamp for the Production of Spirit-gas Incandescent Light, with
Lighting and Extinguishing Contrivance.
I, ALBIN PERLICH of 34 Lauensteinerstrasse, Dresden-Striesen, Germany, Engineer,
do hereby declare the nature of this invention to be as follows:-
The purpose of this lamp is to produce gas from spirit, in order, by mixing the gas
with air, to heat an incandescent body.
Fig. 1 shows this spirit-glowlamp in vertical section, whilst the
Fig. 2-4 illustrate single parts in view and in cross section.
C
The lamp consists, as Fig. 1 shows, of three principal parts, the burner, the lighting
and the extinguishing contrivances. The burner is formed of a double walled hollow
cylinder a, between the walls b and c of which are a number of wicks d, which suck
up the spirit contained in receptacle f. In the burner head g at the upper edge of
the cylinder a the inner case wall c has a conical widening h, in which two or more
tubes i are arranged which run into the bollow burner disc k. The interior of the
burner disc is provided with a vertical tube / having slits or openings m at its upper
end. Beneath these openings is a plate n.
The lower end of the tube in the
cylinder a, has a distributing chamber o, which is provided with outlet openings p.
In the cylinder a, at the height of this distributing chamber, are two or more air
channels g.
Upon the hollow burner disc k, shown in Fig. 1 and 3, is fastened a ribbed
body r
which carries the incandescent substance, and is also for the purpose of
accumulating and distributing heat.
The lighting contrivance consists of a smaller spirit receptacle s, on which a
tube t is arranged, and has a small opening u at its free end, and a wick in its
other end which is in the receptacles.
Underneath this tube t there is a second
tube, the wick of which lies exposed at its open end for lighting. This lighting
contrivance, while in use, is held by tube resting on feet i¹ which stand upon
the receptacle f, and by the tube t which, with the catch a at its front end, is hooked
into a channel q.
The extinguishing arrangement is formed by two channels y and z, which are both
in the short piece c¹, and to which channels tubes a¹ and b' are joined, tube b¹ reaching
into the receptacle f. The short piece c¹ is provided on its outer end with a thread
upon which a socket d' can be moved backwards and forwards, and is closed by a
non-conducting handplate f¹. In the socket d' is a stopper plate 9' made of cork or
similar material, for the purpose of reducing the friction, and carried by a metal
cone h¹.
Then
If the lamp is to be lighted, the tube t of the lighting contrivance is put into one of
the channels q, so that the catch a hooks firmly to the inside of the cylinder a.
the apparatus with its feet is placed upon the receptacle f, and the wick protruding
from the tube v is lighted. The flame thus produced turns the spirit sucked into the
wick of the tube t into gas, and this escapes through the small opening u into the
interior of the cylinder a. Here, through the conical widening h, circulating round
the tubes i, it passes through the perforated surface k¹ upon which it is lighted.
Whilst now the lamp is burning, the upper part of the cylinder a is heated by
the warmth radiating from the burner disc k and the ribbed body r, so that
gasification of the spirit sucked into the wicks d takes place. The gas hereby
developed now goes in the direction of the arrows, through the tubes ii into the

page_text: hollow burner disc_k, encompassing the plate n and passes through the openings m
into the tube l. In this way, the gas in the burner disc is again heated by the
flame on the perforated surface, and in this condition now arrives in the distri-
buting chamber o, passes through the opening p into the interior of the cylinder a,
goes from here into the conical widening h, circulates round the tubes i and passes
through the perforated surface k to the flame.
On coming out of the openings p the gas mixes with the air entering through the
channels g. When this gas reaches the burner head, a further spontaneous gasifica-
tion takes place in the wicks d, so that the lighting contrivance can be detached.
In order to regulate the gas streaming to the perforated surface, a plate having
a female screw is provided inside of the conical widening h, which plate can be
raised or lowered by turning the same on a thread arranged on the tube 1, whereby
the intermediate space between the conical wall and the plate n is extended or
diminished, resulting in a greater or lesser influx of gas.
If the lamp is to be extinguished, the extinguishing contrivance provided on the
burner, already described, is used.
With the burning lamp the socket d' was so far screwed on to the short piece c¹
that the channels y and z were closed by the stopper plate g'. In this position, the
gas developed in the wicks d, distributing itself on all sides, passes into the tube a¹
and the channel y. As this was closed by the plate g', all the gas therefore, developed
in the wicks d, streams through the perforated surface to the flame.
If, however, by means of the hand-wheel f', the socket d' is turned in such way,
that an intermediate space is formed between the mouth of the short piece and the
plate g', then the gas which is in the channel y passes, through this intermediate space
into the channel, and through tube & into the receptacle f.
By this diverting of the gas, the flame on the perforated surface is extinguished.

Lamp for the Production of Spirit-gas Incandescent Light, with
Lighting and Extinguishing Contrivance.
I, ALBIN PERLICH of 34, Lauensteinerstrasse, Dresden-Striesen, Germany,
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 :-
The purpose of this lamp is to produce gas from spirit, in order, by mixing the gas
with air, to heat an incandescent body.
Fig. 1 of the drawings filed with the Provisional Specification shows this spirit
glow lamp in vertical section, whilst the
Fig. 2-4 illustrate single parts in elevation and in cross section.
The lamp consists, as Fig. 1 shows, of three principal parts, the burner, the lighting
and the extinguishing contrivances. The burner is formed of a double walled hollow
cylinder a, between the walls b and c of which are a number of wicks d which suck
up the spirit contained in receptacle f. In the burner head 9 at the upper edge of
the cylinder a the inner case wall c has a conical widening h, in which two or more
tubes i are arranged which run into the hollow burner disc k. The interior of the.
burner disc k is provided with a vertical tube / having slits or openings m at its upper
end. Beneath these openings is a plate n. The lower end of the tube in the
cylinder a, has a distributing chamber o, which is provided with outlet openings p.
In the cylinder a, at the height of this distributing chamber, are two or more
air channels g.

page_text: Upon the hollow burner disc k, shown in Fig. 1 and 3, is fastened a ribbed
body r, which carries the incandescent substance, and is also for the purpose of
accumulating and distributing heat.
The lighting contrivance consists of a smaller spirit receptacle s, on which a
tube t is arranged, and has a small opening u at its free end, and a wick in its
other end which is in the receptacle s. Underneath this tube t there is a second'
tube v, the wick of which lies exposed at its open end for lighting. This lighting
contrivance, while in use, is held by tube v resting on feet which stand upon the
receptacle and by the tube t which, with the catch a at its front end, hooked
into a channel 7.
The extinguishing arrangement is formed by two channels y and, which are
both in the short piece c, and to which channels tubes a' and are joined, tube 6¹
reaching into the receptacle f. The short piece c¹ is provided on its outer end with a
thread upon which a socket d' can be moved backwards and forwards, and is closed
by a non-conducting bandplate. In the socket is a stopper plate g' made of
cork or similar for the purpose of reducing the friction, and carried by a metal
cone h¹.
If the lamp is to be lighted, the tube t, of the lighting contrivance is put into.
one of the channels 9, so that the catch a hooks firmly to the inside of the
cylinder a. Then the apparatus with its feet is placed upon the receptacle f, and
the wick protruding from the tube v is lighted. The flame thus produced turns the
spirit sucked into the wick of the tube t into gas, and this escapes through the small
opening u into the interior of the cylinder a. Here, through the conical widening h,.
circulating round the tubes i, it passes through the perforated surface k upon
which it is lighted.
Whilst now the lamp is burning, the upper part of the cylinder a is heated by the
warmth radiating from the burner disc k and the ribbed body r, so that gasification of
the spirit sucked into the wicks d takes place. The gas hereby developed now goes in
the direction of the arrows, through the tubes ii into the hollow burner disc k, encom-
passing the plate n and passes through the openings m into the tube i. In this way,
the gas in the burner disc is again heated by the flame on the perforated surface, and
in this condition now arrives in the distributing chamber o, passes through the
opening into the interior of the cylinder a, goes from here into the conical
widening h, circulates round the tubes i and passes through the perforated surface k
to the flame.
On coming out of the openings p the gas mixes with the air entering through
the channels 9. When this gas reaches the burner head, a further spontaneous
gasification takes place in the wicks d, so that the lighting contrivance can be
detached.
In order to regulate the gas streaming to the perforated surface, a plate l' having a
female screw is provided inside of the conical widening h, which plate can be raised
or lowered by turning the same on a thread arranged on the tube 1, whereby the
intermediate space between the conical wall and the plate l' is extended or diminished,
resulting in a greater or lesser influx of gas.
If the lamp is to be extinguished, the extinguishing contrivance provided on the
burner, already described, is used.
With the burning lamp the socket d' was so far screwed on to the short piece c¹
that the channels y and 2 were closed by the stopper plate g¹. In this position, the
gas developed in the wicks d, distributing itself on all sides, passes into the tube a¹
and the channel y. As this was closed by the plate g₁, all the gas therefore,
developed in the wicks d, streams through the perforated surface to the flame.
If, however, by means of the hand-wheel ', the socket d' is turned in such
way, that an intermediate space is formed between the mouth of the short piece
and the plate g', then the gas which is in the channel y passes, through this inter-
mediate space into the channel z, and through tube & into the receptacle f.
By this diverting of the gas, the flame on the perforated surface is extinguished.

page_text: 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 a lamp for the production of spirit-gas incandescent light the arrangement of
the double walled, cylindrical hollow body a forming the burner, by which the gas,
developed in the wicks d by the flame at the burner head, passes through tubes i i
and circulating round plate n, into the hollow burner disc k, in order to be again
heated, and then passing through the openings m, goes downward into the tube 1,
streaming out of a distributing chamber o into the interior of the cylinder, from
where, mixed with the air entering by the channels 9 circulating round the tubes i i
and conducted through the perforated surface k¹ to the flame, as described.
2. In a lamp for the production of spirit gas incandescent light, the arrangement
of a conical widening in such way, that by a plate moving upwards and down-
wards on the tube 1, the intermediate space between the two is diminished or
enlarged, and accordingly varying the influx of gas, as described.
3. In a spirit gas incandescent lamp, the arrangement on the burner disc k of a
ribbed body r, which holds the incandescent-body, for the purpose of accumulating
and distributing heat, as described.
4. In the warming arrangement, the combination of a special spirit receptacles,
a tubet filled with a wick and provided with small opening u and catch a, with
burner tube v beneath, by which the spirit in tube t is gasified, as described.
5. The extinguishing arrangement consisting of two tubes a' and ', placed
between the walls of the cylinder a, into which the parallel channels y and z of a
short piece crun, upon which a closed socket d' is moved backwards and forwards
by a handwheel f¹ in order, by means of the cone shaped stopper plate g¹ lying in
it, to open or shut the channels y and for the purpose of diverting the gas into
the receptacle f, as set forth.
