Manufacture of Improved Illuminating Gas.
SELMON KOOPMAN, Merchant, of 19, Worsley Road, Hampstead, London, N.W.,
do hereby declare the nature of this invention to be as follows:-
The object of the invention is to produce a gas, effecting a considerable
saving combined with great lightning power, from heavy mineral oils, including
all kinds of petroleum, from the lamp oil to the heaviest, viz. all the heavy
hydrocarbon, thus avoiding obstructions caused by the separation of tarry in-
gredients. This gas can be used especially with great advantage for the illu-
mination of small communities, big establishments, isolated factories, man-
sions, &c. The apparatus used for the production of the above gas, consists of a
retort in three parts, (or branches) two of which run parallel, the third having a
superposed position in the same direction, so that the three parts are placed at
an equal distance of each other and are mutually connected at the back. The
gas which is developed in the lower two parts rises to the upper one from where
it passes through a purifier, then through a refrigating condenser and finally
finds its way to a gasometer.
Manufacture of improved luminating Gas.
SELMON KOOPMAN, Merchant, of 19, Worsley Road, Hampstead, London, N.W..
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 object of the invention is to produce a gas effecting a considerable saving
combined with great illuminating-power from heavy mineral oils including
all kinds of petroleum from the lightest (lamp oil) to the heaviest, viz. all the
heavy hydrocarbon; thus avoiding all obstructions caused by the separation
of tarry ingredients.
.
This gas can especially be used with great advantage for the illumination of
small communities, large establishments, isolated factories, mansions, etc.
The system consists of:
1. A cast iron retort with three arms or sections, two of which run parallel,
the third having a superposed position in the same direction and all three being
placed at an equal distance from each other mutually connected at the back.

page_text: 1. A furnace G (Fig. 2 and 3).
2. A slab consisting of three fire-proof bricks L the largest of which is placed
in front in a flat position, whilst the two others are fixed on behind in the same
manner, thus forming altogether one slab, causing a continuous and equal circu-
lation of the flames, serving at the same time as an entire partition between
. the retort and furnace.
3. A stand of fire-proof bricks with basin H, supporting arm C serving to
protect the same from the flames which are concentrated by the draught on
those parts now covered by the basin.
4. A vault of fire-proof bricks. J (Fig. 2 and 3) so constructed that at the
sides and at the top space exists between the same and the upper section of the
retort, so that, on meeting the two lower sections it is entirely joined in a bent
shape at the fire-proof brick basins on which those two lower sections are fixed.
5. A bridge of fire-proof bricks see K (Fig. 2).
The flames move towards the indicated arrows (Fig. 2) proceeding from the
furnace G, after first having come into contact with the fire-proof bricks at the
bottom, through the apparture G along between the two lower sections
encircling the entire retort from outside, then along M and N to the chimney O.
Besides the retort and oven there are connected with this installation like in
all constructions for the manufacture of gas from mineral-oils, as shown at
Fig. 4, a purifier P, a refrigerator R, a reservoir S containing the necessary
oil which passes through the little tubes T and is conducted towards sections A
and B. The developed gas proceeds from the upper-section C, through pipe F
to the purifier, from there through the refrigerator and finally through pipes V
to the gasometer.
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. A retort consisting of three arms or sections to obtain cheap and excellent
gas by a process of quick development.
2. In connection with the retort described above an oven shown by Fig. 2.
There will be seen a slab consisting of three fire-proof bricks L, the largest of
which is placed in front in a flat position, whilst the two others are fixed on
bebind in the same manner, thus forming altogether one slab causing a con-

page_text: tinuous and equal circulation of the flames, serving at the same time as an
entire partition between the retort and furnace;-a stand of fire-proof bricks
with basin H, supporting arm C, serving to protect the same from the heat of
the flames which are concentrated by the draught on those parts now covered
by the basin.
3. A vault of fire-proof bricks J (Fig 2 and 3) so constructed that at the
sides and at the top space exists between the same and the upper-section of the
retort, so that, on meeting the two lower sections, it is entirely joined in a bent
shape at the fire-proof brick basins on which those two sections are fixed.
