J. Brandt and G. W. von Nawrocki, of 124, Leipzigerstrasse, Berlin, Germany,
Patent Agent, for an Invention of "IMPROVEMENTS IN APPARATUS FOR
PRODUCING OIL-SOOT." A communication by Otto Thalwitzer; of the Firm of

PROVISIONAL SPECIFICATION left by the said Gerard Wenzeslaus von
Nawrocki at the Office of the Commissioners of Patents on the 7th April
1880.
GERARD WENZESLAUS VON NAWROCKI, of the Firm of J. Brandt and G. W. von
Nawrocki, of 124, Leipzigerstrasse, Berlin, Germany, Patent Agent, "IMPROVE-
MENTS IN APPARATUS FOR PRODUCING OIL-SOOT." A communication from Otto
Thalwitzer, of the Firm of A. Biermann & Co., of Halle a/Saale, Germany.
This Invention relates to improvements in apparatus for producing oil soot, and
consists of a vertical tube point of a step block carried on the bottom of a
cylindrical box or casing containing the apparatus.
The tube is provided at its upper end with a funnel, into which cooling water is
poured and flows out through openings in the tube immediately above a circular
plate of thin cast or wrought iron arranged horizontally and secured at its centre to
the tube.
Round the periphery of this plate is a vertical rim of tin plate, at the top of
which is a suitable pipe through which the cooling water runs into a gutter
arranged round the top of the cylindrical box or casing, the water being carried off
from this gutter by a suitable pipe. The vertical tubo is carried near its upper end
in a bearing, and to it at that part is attached a worm wheel geared into by a
worm driven by any suitable power. At the underside of the circular plate radially
therewith is fixed a scraper, the edge of which is formed with a strip of leather in
contact with the lower surface of the plate.
Opposite the scraper, at the bottom of the cylindrical box or casing, is placed
a burning lamp which sucks up the oil for its consumption by a flat and wide
wick.

page_text: The operation is this apparatus is as follows:-The vertical tube is caused to
revolve by the action of the worm wheel, the circular plate thereby receiving a slow
rotary movement, and a small stream of water being poured into the funnel at the
top of the tube, this water passes down the latter and through the openings
therein on to the circular plate, which is thereby kept cool. The burning lamp 5
filled with paraffin or other oil is brought as near to the circular plate as is
necessary for the cooling of the flame and the most perfect extraction of the carbon
which, in the form of soot, attaches itself readily to the plate owing to its coldness
and by the condensation of the steam produced. The revolving plate presents
continually to the flames new and clean surface in consequence of the soot being 1
scraped away by the scraper as soon as deposited, and brought away through a
pipe or shoot into a collecting barrel.

Nawrocki, of 124, Leipzigerstrasse, Berlin, Germany, Patent Agent. "IMPROVE-
MENTS IN APPARATUS FOR PRODUCING OIL-SOOT." A communication from Otto
Thalwitzer, of the Firm of A. Biermann and Co., of Halle a Saale, Germany.
The apparatus forming the object of the present Invention is illustrated by the
accompanying Drawings:-Figs. 1 and 2, and consists of a round metal plate A
provided with a flange a and fixed on a vertical shaft b supported by the bearing B
and carrying at its upper end a worm wheel d set in motion by a worm.
The plato A is cooled by water admitted through a pipe g, and the flange a is
provided with a discharge pipe h, through which the cooling water runs into the
groove D, surrounding the whole apparatus. Underneath the plate A a number of
lamps J are applied, which are fed with oil by a common pipe l. H is an oblique
scratcher or blade, tho working edge of which is formed by a strip of leather, and
touches the lower surface of the plate A.
For manufacturing soot a slow rotary motion is imparted to the apparatus by
means of the worm and worm wheel, and a slight current of water directed upon the
plate A through the pipe g. The lamps J filled with paraffin oil derived from
lignites, or with any other suitable oil, are ignited and approached to the plate A
as far as is necessary for cooling the flame so as to deposit the greatest possible
quantity of soot. The latter adheres to the cold surface of the plate which is also
kept damp by the aqueous vapor formed during the combustion. The revolution of
the plate serves to bring the flame continually into contact with new and clean
portions of the plate, the soot being continually scraped off by the blade or scraper
placed opposite the flames and conducted through a channel into a collecting
trough.

CLAIM.
The apparatus for the manufacture of oil-soot, substantially as described, and
especially the application of a revolving and constantly cooled metal plate, one
side of which is in contact with a suitable flame or flames while the lamp black
5 produced is removed and collected by means of a scraping device.
In witness whereof, I, the said Gerard Wenzeslaus von Nawrocki, have
hereunto set my hand and seal, this Fourth day of October, A.D. 1880.
