Vienna, in the Empire of Austria, Solicitors of Patents and Engineers. " IMPROVE-
MENTS IN OR APPLICABLE TO REGULATOR GAS BURNERS." A communication from.
Josef Janky, Julius Rimanoczy, and Coloman Rimanoczy, of Vienna, Austria.
This Invention relates to certain improvements in or applicable to regulator gas
burners. These improved regulators consist essentially of pieces of (Bengal) cane
suitably prepared and hardened, and inserted into shells or cases, which are placed
into the gas-burners or into pieces specially adapted for their reception, upon which
the burners or burner tips are screwed. The size of these shells depends on the size
of the burners, and with different diameters their length varies from 1/16 to 1/2 inch.
Inserted into the burner they regulate the flame by opposing to the gas from
200 to 300 capillary channels, through which the gas must pass before reaching the
nipple.
The cane is prepared in the following manner :-
10
Pieces about two feet long are soaked for about two weeks in a bath consisting
of water and alcohol in equal parts. This bath must be kept lukewarm and be
renewed about every two days. After this the pieces are freed from all watery
mucous and soft or pitby particles by forcing the blast of an air pump, compressor,
or fan through them, whereby the fine channels are opened. Now the canes are cut
into small pieces, dried, and again rinsed for several days, first in warm, then
in cold water, again cleaned by being blown through, and subsequently dried in a
well aired place.

page_text: Being perfectly dry the pieces, in order to harden and colour them, are slowly
boiled in a mordant composed of 5 parts (by measure) extract of gall nuts, 40 parts
logwood (Campeache), 3 parts green vitriol, 40 parts water, and 12 parts alcohol,
for about 48 hours.
The pieces are allowed to cool in the mordant, and are then rinsed in clean water,
blown through, dried, and are ready for insertion in the shells. These shells consist
of tubing made of metal, glass, porcelain, clay, or similar material. The pieces of
cane, the length whereof depends upon the size of the flame, are inserted into the
shells by means of a press. The shells are somewhat longer than the pieces of cane,
so that the former will project over the latter about from 1/8 to 3/16 of an inch.
The combination of such a shell with a piece of the prepared cane forms the
regulator for the gas burners.
The regulator is placed immediately beneath the flame into the burner itself,
or into a metal coupling piece inserted for this purpose between the burner and
supply pipe.
Besides the flame being so regulated by this arrangement that it burns steadily
and quietly, avoiding any hissing and flickering of the same, while the air in the
room which is illuminated by it remains pure, there is by the use of these regu-
lators a saving of from 18 to 35 per cent. effected upon the consumption of gas.
This regulator, it is obvious, can easily be applied to gas burners of any
description.
In the accompanying Drawing is represented the means for carrying the Invention
into practical effect.
a is a piece of cane.
b, the shell or case into which the prepared.cane is pressed.
c and d are two metal pieces, which can be screwed into each other, thus forming
the coupling piece or boxing for the reception of the shell and the cane, and which
is inserted between the supply pipe and the burner or burner tip.
Having thus described the nature and particulars of the said Invention, I
claim,
-
Firstly. In a gas burner the employment of the piece a of (Bengal) cane, prepared
by soaking it in a luke warm bath composed of equal parts of water and alcohol,
rinsing it first in warm then in cold water, and freeing it from all soft pithy
particles by forcing a strong blast through the same, so that the cane in section
will appear perforated with a large number of small holes, as and for the purpose
set forth.
Secondly. The preparing and hardening of the. perforated cane in a mordant
composed of the ingredients and in the proportions as herein described.
Thirdly. The combination of the so prepared cane-regulator piece a with a
tubular shell b of metal, glass, porcelaine, clay, or other equivalent material, and an
intermediate piece or coupling consisting of two parts, and adapted for the reception
of the shell and cane, the whole forming a gas burner regulator, substantially as
herein described and shown in and by the accompanying Drawings.
In witness whereof, I, the said Heinrich Zwanziger, have hereunto set my
hand and seal, this 22d day of April, One thousand eight hundred and
eighty one.
