PROVISIONAL SPECIFICATION.
Improvements in the Manufacture of Carbon Bisulphide.
We, THOMAS PARKER, Electrical Engineer, and ALFRED EDWARD ROBINSON,
Technical Chemist, both of (Commercial Road Wolverhampton in the County of
Stafford, do hereby declare the nature of this invention to be as follows:-
This Invention has for its object the manufacture of carbon bisulphide by a
continuous and economical process.
In proceeding according to these Improvements, we place a mass of charcoal in a
suitable chamber between two carbon electrodes and pass through the mass a current
of electricity having a sufficient density to bring the charcoal to a high temperature.
As soon as the desired temperature in the charcoal has been attained, we pass vapour
of sulphur through the heated mass. The vapourous carbon bisulphide produced by
the combination of the sulphur with the carbon is led off and condensed in the usual
known manner.
The supply of charcoal during the process may be replenished continuously by
automatic feeding devices or by hand.

COMPLETE SPECIFICATION.
Improvements in the Manufacture of Carbon Bisulphide.
We, THOMAS PARKER, Electrical Engineer, and ALFRED EDWARD ROBINSON,
Technical Chemist, both of Commercial Road Wolverhampton in the County of
Stafford, 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 :-
This Invention has for its object the manufacture of bisulphide of carbon by a
continuous and economical process.
In proceeding according to these Improvements we place a mass of charcoal
between two suitable electrodes which are preferably constructed of carbon and are
contained within a suitable vessel or chamber, and connect the electrodes with the
poles of a dynamo or other source of electricity capable of yielding a current of
sufficient density to bring the charcoal to the high temperature known to be
necessary to ensure its combination with sulphur vapour.
As soon as this high temperature in the charcoal has been attained by the passage
of the current, we pass the vapour of sulphur through the heated mass, and we
continue to pass the vapour through the mass so long as the necessary high
temperature is maintained.
The supply of charcoal is renewed continuously or from time to time as may be
required, and it may be supplied to the space between the electrodes either by hand
or by means of automatic feeding devices.
The vapourous bisulphide of carbon produced by the combination of the sulphur
with the carbon, is led off and condensed in the usual manner and by known
means.
Having now particularly described and ascertained the nature of our said Inven-
tion and in what manner the same is to be performed, we declare that what we
claim is,
(1) The manufacture of carbon bisulphide substantially as and by the means
herein before described.

page_text: (2) In the manufacture of carbon bisulphide, heating the charcoal between two
carbon electrodes by means of a current of electricity, substantially as herein before
described.
