IMPROVEMENTS IN OBTAINING POWER WHEN BISULPHURET OF CARBON IS USED
Year: 1858

page_text: LETTERS PATENT to John Oliver York, of Paris, Engineer, for the
Invention of "IMPROVEMENTS IN OBTAINING POWER WHEN BISULPHURET OF
CARBON IS USED." -A communication from Bernard Hughes, of Rochester,
New York, America.
Sealed the 2nd August 1858, and dated the 23rd April 1858.
PROVISIONAL SPECIFICATION left by the said John Oliver York at the
Office of the Commissioners of Patents, with his Petition, on the 23rd
April 1858.
I, JOHN OLIVER YORK, of Paris, Engineer, do hereby declare the nature of
the Invention for "IMPROVEMENTS IN OBTAINING POWER WHEN BISULPHURET OF
CARBON IS USED," to be as follows:-
This Invention has for its object improvements in obtaining power when
bisulphuret of carbon is used. Heretofore when using bisulphuret of carbon,
the vapour thereof has been combined with steam, and the two have been
caused to work ordinary engines, and the bisulphuret of carbon has then
been separated from the water after condensation. Now, my improvements
consist in employing the vapour of bisulphuret of carbon without mixing it
with steam, and in condensing the vapour and again and again using the
bisulphuret of carbon. The arrangement of the boiler and machinery may.
be greatly varied, but I prefer that the generator of vapour should be within
an ordinary steam boiler, and consist of a vessel having through it a number

page_text: of tubes, within which the steam passes. The bisulphuret of carbon is
pumped or forced into the vessel or generator in a quantity sufficient to
produce a stroke of the engine or engines connected therewith, and the
vapour after passing from the engine or engines is condensed by a surface
condenser, such as heretofore used, which is worked by an air pump; and the
condensed bisulphuret of carbon is again and again used by being pumped
or forced into the generator or heated vessel.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Oliver York in the Great Seal Patent Office on the
19th October 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
OLIVER YORK, of Paris, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-third day of April, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said John Oliver York, Her special licence that I, the said John Oliver
York, my executors, administrators, and assigns, or such others as I, the said
John Oliver York, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the term therein expressed, should and lawfully might make,
use, exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
.MENTS IN. OBTAINING POWER WHEN BISULPHURET OF CARBON IS USED," a com-
munication from Bernard Hughes, of Rochester, New York, America; upon
the condition (amongst others) that I, the said John Oliver York, my exe-
cutors or administrators, by an instrument in writing under my, or their,
or one of their hands and seals, should particularly describe and ascertain
the nature of the said Invention, and in what manner the same was to be
performed, and cause the same to be filed in the Great Seal Patent Office
within six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Oliver York, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say :-

page_text: This Invention has for its object improvements in obtaining power when
the vapor of bisulphuret of carbon is used. Theretofore when using bisulphuret
of carbon, the vapor thereof has been combined with steam, and the two have
been caused to work ordinary engines, and the bisulphate of carbon has then
been separated from the water after condensation. Now, the improvements
consist in employing the vapour of bisulphuret of carbon as motive power
without mixing it with steam, and in condensing the vapor, and again and
again using the bisulphuret of carbon. The arrangement of generators of
machinery necessary to carry out the improvements may be greatly varied.
I prefer that the generator of the vapour of bisulphuret of carbon should
consist of a steam or vapour-tight cylindrical chamber, into the ends of which
a number of small tubes are inserted and made steam or vapour-tight; this
chamber is placed either in the interior of an ordinary steam boiler (having
connected with it the usual and necessary appurtenances of steam boilers,
or in a separate steam chamber communicating with the said steam boiler,
so that the steam from the same may be around the shell and within the
tubes of the generator. Into this generator a pipe is inserted to supply at
each stroke of the engine the required quantity of bisulphuret of carbon,
which when thus introduced is immediately converted into vapour of any
required pressure by the heat of the steam within the tubes and around the
shell of the generator. The vapour thus formed is then passed through a pipe
to the working cylinder of an ordinary steam engine. The generator is to be
fitted with safety valves, which should, in order to prevent waste, be in com-
munication with the condenser.
The first supply of bisulphuret of carbon may be introduced by a hand-
pump, but after the first stroke of the engine it may be supplied to the gene-
rator as follows:-The vapour of the bisulphuret of carbon supplied from and
created in the generator passes through a pipe as before described, and works
an ordinary steam engine, and is then exhausted into a surface condenser and
therein condensed; the bisulphuret of carbon thus produced by condensation
is then removed by an ordinary air pump worked by the engine, and is
delivered into a chamber generally called the hot well in ordinary condensing
engines, from the hot well it is passed by a pump into the generator, where it is
again converted into vapor, and this process is continued as long as the
engine works. Any waste occurring in the passage of the vapour from the
generator to the condenser may be made up by a reserve quantity of bisul-
phuret of carbon.
Having thus described the nature of the Invention, and means of carrying
out the improvements, I do not confine myself to such means, as variations

page_text: may be made therein.
In some cases it may be preferred to regulate the
generation of the vapour by the degree and quantity of heat supplied to the
generator, instead of limiting the quantity of bisulphuret of carbon supplied for
each stroke of the engine. I claim as the Invention the employment of the
vapour of bisulphuret of carbon as herein described, in place of combining such
vapours with steam.
In witness whereof, I, the said John Oliver York, have hereunto set
my hand and seal, this Eighteenth day of October, in the year of our
Lord One thousand eight hundred and fifty-eight.
JOHN OLIV YORK. (L.S.)
