APPARATUS
This invention relates to the production of light and heat from the evaporation
of suitable hydrocarbons including alcohol, wood spirit and others by means of an
apparatus or lamp of a construction such as that hereinafter described.
A suitable construction of apparatus or lamp for carrying out my invention is as
follows:-
I employ a suitable receiver for containing alcohol or spirit; through the cover
of the receiver passes a tube or tubes; the said tube or tubes extends or extend
nearly to the bottom of the receiver, and to a certain distance above the cover;
within the tube or tubes I place any suitable porous material such as cotton wool,
the said porous material extending from the bottom of the tube or tubes to within
a short distance of the top thereof. The upper end of the tube or tubes above the
top of the porous material is perforated with a number of holes for the purpose
hereinafter described. From the said tube or tubes and below the line of the top
of the porous material passes what I term an exciter made of metal or other suitable
heat transmitting material.
A burner or burners consisting of platinum wire or gauze fitted into a disc or discs
of suitable refractory material is or are suspended over the top of the tube or tubes
and at a distance therefrom,
The operation of the apparatus or lamp is as follows:-
The receiver is charged with suitable alcohol or spirit such as methylated spirit
and heat is applied to the exciter which becoming heated heats the burner or

page_text: burners and the tube or tubes whereby the spirit rises to the top of the tube or
tubes by capillary attraction. In some cases instead of applying heat obtained by
combustion a similar effect is obtained by passing an electric current through the
tubes. Volatilization or evaporation is induced in the top part of the tube or tubes
above the porous material and the vapour meets with the air entering the tube or
tubes through the hereinbefore described perforations. The mixture of vapour and
air thus induced will continue to form and will rise to the burner or burners
causing the same to become incandescent and to remain incandescent until the
spirit is consumed.
0
The exciter is made adjustable so as to allow of regulating the evaporation and
consequently the extent of incandescence of the burner or burners.
I have described the burner or burners as being made of platinum but iridium or
other heat resisting metal may be employed.
The burner or burners is or are enclosed within a globe or lantern to which the
air has access.
In some cases I use electric currents in connexion with the burner, or burners
constructed as above described or with other burners of a similar character; by
_ causing the currents. to pass through the metallic wires while they are-in-an-
incandescent or heated state the light is greatly intensified by employing com-
paratively moderate currents-The use of these currents in combination with my
burner will enable a very powerful light to be obtained at a moderate cost. In the
case of ordinary incandescent electric lamps which are made to act by means of 'say
for example a given number of accumulators producing the requisite current I am
-able to lessen the number of accumulators required and produce..an-equal.or.better
effect by combining with the electric incandescent lamp the action of my improved
lamp or apparatus.

"IMPROVEMENTS IN THE PRODUCTION OF LIGHT AND HEAT AND APPARATUS
THEREFOR
"
This invention relates to the production of light and heat from the evaporation
of suitable liquid hydro-carbons including alcohol, wood spirit and others by means
of an apparatus or lamp of a construction such as that hereinafter described.
A suitable construction of apparatus, or lamp for carrying out my invention is as
follows:-
I employ a suitable receiver for containing alcohol or spirit; through the cover
of the receiver passes à tube or tubes; the said tube or tubes extends or extend
nearly to the bottom of the receiver, and to a certain distance above the cover;
within the tube or tubes I place any suitable porous material such as cotton wool,
the said porous.material extending from the bottom of the tube or tubes to within
a short distance of the top thereof. The upper end of the tube or tubes above the
top of the porous material is perforated with a number of holes for the purpose
hereinafter described. From the said tube or tubes and below the line of the top
of the porous material passes what I term an exciter made of metal or other suitable
hent transmitting material or the tube itself may be so constructed as to form the
exciter as hereinafter explained.
A burner or burners consisting of platinum wire or gauze fitted into a disc or discs
of suitable refractory material is or are suspended over the top of the tube or tubes
and at a distance therefrom, or when the tube forms the exciter the platinum wire is
fixed in an opening in the tube.
When an independent exciter is employed it is made adjustable so as to allow of
regulating the evaportion and consequently the extent of incandescence of the burner
or burners.
I have described the burner or burners as being made of platinum but iridium
may be employed.
The burner or burners is or are enclosed within a globe or lantern to which the
air may or may not have free access.
In some cases I use electric currents in connection with the burner or burners
constructed as above described or with other burners of a similar character; by
causing the currents to pass through the metallic wires while they are in an incan-
descent or heated state the light is greatly intensified by employing comparatively
moderate currents. The use of these currents in combination with my burner will
enable a very powerful light to be obtained at a moderate cost. In the case of
ordinary incandescent electric lamps which are made to act by means of say for
example, a given number of accumulators producing the requisite current, I am
able to lessen the number of accumulators required and produce an equal or better
effect by combining with the electric incandescent lamp the action of my improved
lamp or apparatus,
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1, is a side
elevation partly in section of an apparatus or lamp constructed according to my
invention and provided according to this modification with an exciter ; figures 2,
and 3, are a front elevation and a section respectively of a similar construction of
lamp without an independent exciter; figures 4, and 5, side and front elevations

page_text: shewing the construction of lamp I employ when used in connection with currents
of electricity; figures 4, and 5*, are enlarged details of the burner of the lamp
shewn in figures 4, and 5; figure 6, elevation of a pair of accumulators to be used
with a lamp of the character shown in figures 4, and 5; figure 7, elevation
shewing the lamp represented in figures 4, and 5, connected to the accumulators and
placed within a receptacle or stand ready for use, the burner and the lamp however
being of the construction shewn in detached front and side views at figures 8,
and 9; figures 10, and 11, detached enlarged views shewing two constructions of
burner suitable for use with the lamp shewn in figures 2, and 3. Similar letters in
all the figures represent similar or corresponding parts.
•
In figure 1, a, is the receiver containing the alcohol or spirit; b, the tube passing
through the cover c, of the receiver and extending nearly to the bottom of the
receiver a, as shewn; d, the porous material such as cotton wool placed within the
said tube; e, the air holes in the tube b; f, the exciter which may be adjusted
by the ring g, and set screw h, or by other suitable means; i, is a disc fixed to the
top of the exciter f, and carrying platinum or iridium wire or gauze j, forming the
burner which is thus suspended over the top of the tube b, at a suitable distance
therefrom.
The operation of the apparatus or lamp is as follows:-
The receiver a, is charged with suitable alcohol or spirit such as methylated
spirit and heat is applied to the exciter f, which becoming heated heats the
burner j, and the tube b, whereby the spirit rises to the top of the porous material
in the tube b,. by capillary attraction. In some cases instead of applying hent
obtained by combustion a similar effect is obtained by passing-an-electric current
through the tube b. Volatilization or evaporation is induced in the top part of the
tube b, above the porous material d, and the vapour meets with the air entering
the tube through. the hereinbefore described perforations e. The mixture of vapour
and air thus induced will-continue-to-form and will rise to the burner i, j, causing.
-the-same-to-become-incandescent_and_to_remain incandescent until the spirit is
consumed.
The lamp or apparatus shewn in figures 2, and 3, is constructed and operates
substantially the same as the lamp herein before described and shewn in figure 1,
the only difference being that instead of employing a separate or independent
exciter the upper part of the tube is cut away in the front part, the back part f
forming the exciter, the burner being formed by platinum wire j, placed in the cut
away part as shewn clearly in the detached enlarged view at figure 10. Or instend
of the platinum wire being fitted in a cut away part of the tube b, it may be
adapted to a separate tube 61, of suitable material such as steatite which is fitted
or placed on the top of the tube b, as shown in the detached enlarged view at
figure 11.
In the lamp shewn in figures 4, and 5, to be used in conjunction with currents
of electricity, the upper end of the tube b, is flattened as shewn at k, figure 4, the
front side being perforated with holes as clearly shewn at ligure 5; at a short
distance in front of the said perforations is fixed a piece of platinum wire o,
forming the burner preferably bent into the shape shewn in figure 4*, and held or
supported by rods 1, (or equivalent means) connected by the wires m, to
accumulators such as those shewn at n, n', figure 6, or to other suitable source of
electricity
Or the burner for this construction of lamp may be constructed as shewn in
figures 8, and 9, in which the perforations in the flattened part of the tubo are
dispensed with the flattened part of the tube being instead split or open at the
sides and top and a piece of platinum wire o, forming the burner being placed
around the opening at the sides and top of the flattened part of the tube b.
When the lamp or apparatus is joined up with the accumulators and placed
within a suitable stand or receptacle as shewn in figure 7, a very powerful
light will be obtained. Instead of the accumulators a small dynamo machine
operated by clockwork may be employed placed within the stand or receptacle

page_text: In all cases the burner is enclosed within a globe or lantern as herein before
described such globe or lantern not being shewn in the drawing.
I have described and shewn my improved lamps or apparatuses as being
provided with only one tube b, and one burner but it will be evident that two or
more tubes and burners may be employed.
For the purpose of heating the air before it mixes with the vapour, I
sometimes provide the tube b, with a concentric tube of suitable length the air
becoming heated in its passage through the space between the two tubes.
For the better diffusion and henting of the vapour before it reaches the burner I
sometimes employ a ring of clay or other suitable refractory material corrugated
or otherwise on its periphery and placed in the tube b, on the porous material d,
and to prevent flaming a loose packing of suitable material can be placed in the
upper end of the tube b.
Having thus described my invention and suitable means for carrying the same
into practice I would have it understood that what I claim and intend to be
protected by the herein in part recited Letters Patent is :-
Firstly. The production of light and heat from the evaporation of suitable
liquid hydrocarbons including alcohol, wood spirit and others (in combination or
not with currents of electricity) by the employment of apparatus constructed
substantially as herein before described.
Secondly. The use in the manner indicated of liquid hydrocarbon substances for
aiding and intensifying the action of lamps which give light by the agency of
electricity substantially as herein described.
Thirdly. The improved lamps or apparatuses for producing light and heat from
the evaporation of suitable liquid hydrocarbons constructed and operating as
herein before described and represented in figures 1, 2, and 3, of the accompanying
drawing.
Fourthly. The improved lamp or apparatus for producing light and heat from
the evaporation of suitable liquid hydrocarbons in conjunction with currents of
electricity constructed and operating as herein before described and illustrated in
figures 4, 5, and 7 of the accompanying drawing.
In Witness whereof I the said Elieson Prosper Chaimsonovitz have hereto set
my hand and seal this eighth day of May in the year of our Lord one
thousand eight hundred and eighty three.
