Improved Means and Arrangement of Building for Producing
Lamp Black for Making Printers' Ink and other Substances
for which such "Black" is Used.
I, CHARLES TALMAGE BASTAND, of Warner Street, New Kent Road, Surrey,
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 object of this invention, is to obtain Lamp Black from the burning of oil, or
its equivalent within a close chamber to which only sufficient air is permitted to enter
to support combustion. One side of said chamber is open at the top. and leads into
another chamber, into which the blacks given off from the flame of the burning oil, or
its equivalent can deposit or gravitate one wall of the second chamber being cut short
at the bottom to allow other blacks which may be carried on by the draught to deposit
themselves in a second depositing chamber in which curtains or screens are arranged
for causing the blacks to be carried on by the draught in a zigzag manner, said
curtains or screens being worked like ordinary window blinds or otherwise from the
outside of the structure and scraped when raised to remove the blacks which may
adhere to them.
Any number of these chambers may be arranged in one structure and any number
of curtains may be fitted as desired.
Each depositing chamber has an opening in the front wall covered by a sliding
flap or shutter which can be raised or opened when the Lamp Black has to be
removed.
These shutters or flaps are preferably within a gangway to allow of sacks being
filled without interfering with the working, said gangway being closed and provided
with sufficient windows to give light to enable a man to work within it.
At the end farthest from the black producing chamber, is a chimney, the top of
which is capable of being closed when desired especially when all the chambers have
to be emptied, the air inlet being also closed.
The roofing of the chambers is flat but is surmounted by a semicircular cover for
protecting the roof proper against wet and serving as a cover for those curtains which
pass through the roof.
The black producing chamber may be supplied with cotton waste or other refuse
and the oil or its equivalent supplied from a tank, said oil flowing on to the cotton
waste from a T branch perforated for distribution.

page_text: My invention will be understood by the annexed drawings, in which at Figure 1 I
show a part sectional prospective elevation.
Figure 2 is a sectional plan and Figure 3 a top plan with a cover removed.
A is the chamber, in which the "black" or soot is produced from the burning of
oil and cotton waste or other substances within the vessel B, the oil being supplied by
the perforated branch C from its connection with an oil tank.
D is the air inlet for supporting combustion, E is the first partition wall stopped
short from the top and F is the second partition stopped short at bottom, so that the
particles of soot or black not deposited in the first depositing chamber G may rise up
again between F and the first curtain H as indicated by arrows and then over the top
of H thence down and under I travelling up and down in a zigzag manner through the
several chambers, the particles of black depositing themselves in the several
chambers G, J, K, L, M, vapour alone escaping by the chimney N. This chimney N
is provided with a closing plate P so that when the black has to be removed from
either of the chambers, the valve of the air inlet D is closed and also the chimney
cover P all draught being thereby stopped, an attendant can lift either of the flaps or
sliding doors Q which cover openings Qwithdraw the black from the chamber and
fill it into bags.
These sliding doors are within a gangway R lighted by windows S, the inlet passage
being at T from which the filled sacks can be removed.
The curtains H, H', are suspended from rollers within the chamber J and reach to
the bottom of said chamber as a partition but the curtains I, 1', are suspended from
rollers I³ from above the roof U, scrapers being applied within the chamber J for
removing black from the curtains while being raised.
In order to protect the roof U and also the upper rollers 12, 12, I cover the same
with a semi-circular covering V of say, corrugated iron but any other form of
roofing may be adopted and instead of a semi-circular covering over the roof U it
may be over the parts only where the rollers 1', 1', are situate.
In the drawing, I have shown six depositing chambers with curtains in the alternate
ones but when the curtains are raised those chambers are free to enable a man to
enter.
By the use of the curtains the zig-zag route, along which the sooty particles might
travel is increased without making the building of a bulky character and these
curtains form an essential feature in my invention for the purpose.
Having now particularly described and ascertained the nature of this invention and
in what manner the same is to be performed I declare that what I claim is :—
1. The general construction and arrangement of building in which Lamp Black is
produced, said building having partitions stopped top and bottom alternately to form
chambers in which the sooty particles deposit themselves for after collection as
described and substantially as shown in the annexed drawings.
2. In connection with a building, such as that previously described and in which
Lamp Black can be produced, a series of curtains arranged within one or more
chambers for increasing the distance which said blacks have to travel for checking
their progress and inducing deposit within the chambers all as set forth.
3. Fitting some of the curtains for operation within the chambers and some for
operation outside the chambers but capable of being scraped from the inside for the
removal of Lamp Black deposited on them as described.
