IMPROVEMENTS IN THE MANUFACTURE OF COMPOUNDS IN THE NATURE OF KAMPTULICON
Year: 1866

page_text: LETTERS PATENT to Alexander Parkes, of Birmingham, in the County of
Warwick, for the Invention of "IMPROVEMENTS IN THE MANUFACTURE OF
COMPOUNDS IN THE NATURE OF KAMPTULICON."
Sealed the 4th December 1866, and dated the 6th June 1866.
PROVISIONAL SPECIFICATION left by the said Alexander Parkes at the
Office of the Commissioners of Patents, with his Petition, on the 6th
June 1866.
I, ALEXANDER PARKES, of Birmingham, in the County of Warwick, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MANUFACTURE OF COMPOUNDS IN THE NATURE OF KAMPTULICON," to be as
follows:-
This Invention has for its object improvements in the manufacture of
compounds in the nature of kamptulicon. For this purpose I take oil, by
preferenco castor oil, and change it by means of chloride of sulphur in'o a
platsic mass, and with this I mix and thoroughly combine cork dust, saw dust,

page_text: or loose fibre, and in this way I obtain compounds very similar to kamp-
tulicon and which may be used for similar purposes, these compounds may
also be shaped in moulds.
The following proportions are suitable, 100 parts of oil, 10 to 15 parts of
chloride of sulphur dissolved in 20 to 30 parts of bisulphide of carbon or
other solvent, 100 to 500 parts of cork dust, saw dust, or loose fibre; india-
rubber and gutta percha may also be added to the above-named compounds.
A surface of parkesine may be applied to sheets and articles made of these
compounds.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alexander Parkes in the Great Seal Patent Office on the
6th December 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
PARKES, of Birmingham, in the County of Warwick, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing. date the Sixth day of June, in the year of our Lord

reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Alexander Parkės, Her special licence that I, the said Alexander Parkes,
my executors, administrators, and assigns, or such others as I, the said
Alexander Parkes, 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 THE MANUFACTURE OF COMPOUNDS IN THE NATURE OF KAMPTULICON,'
upon the condition (amongst others) that I, the said Alexander Parkes,
my executors 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 Alexander Parkes, do hereby declare
the nature of the said Invention, and in what manner the same is to be

page_text: performed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in the manufacture of
compounds in the nature of kamptulicon. For this purpose I take oil, by pre-
ference castor oil, or linseed or cotton seed oil may bo conveniently used, and I
change the oil by means of chloride of sulphur into a plastic mass, and with
this I mix and thoroughly combine cork dust, saw dust, or loose fibre, in this
way I obtain a compound very similar to kamptulicon and which may be
used for similar purposes. These compounds may also be shaped in moulds.
The following is the manner in which I prefer to conduct the opera-
tion. I take, say, 100 parts of oil, and I add thereto from 10 to 15
parts of chlorido of sulphur dissolved in 20 to 30 parts of bisulphide of carbon.
If I desire to obtain a soft material capable of holding a large proportion of
cork dust, saw dust, or fibre, then I use the smaller quantities above given, and
on the contrary I use the larger proportions when I desire to obtain a tough
product. In place of bisulphide of carbon other solvents of chloride of
sulphur may be employed, for example, mineral naptha is very conveniently
used. The changed oil obtained I wash well with water, and I then incorporate
with it the cork dust, saw dust, or loose fibre, by passing it together with these
materials between rollers heated with steam.
For a floor cloth I prefer to use an oil compound of medium toughness and
to combine therewith in the manner described, about 300 parts of cork dust
and 100 parts of loose fibre. Tho fibre I prefer to employ is to cut to about
quarter inch lengths. This compound is then rolled out into sheets as is usual
in making kamptulicon. In place of cork dust, saw dust, which is cheaper
may be used, but an inferior article is obtained or the fibro may be used alone
in the proportion of, say, 300 parts, and in this way a tougher and less elastic
article is obtained. Such compounds are also advantageously used in making
steam joints and packings, and in this case I add black lead or it may be
gypsum or chalk or powdered soapstone or such like material to the other
ingredients. A good steam packing is obtained by compounding in the
manner described 100 parts of changed oil of the tougher description, 250
parts of cork dust, 20 parts of black lead or powdered soapstone. Where
there is no friction gypsum or chalk may be substituted for black lead or soap-
stone. For floor cloth, india-rubber, and gutta percha may be added to the
other ingredients, the proportion in which this mixture may advantageously be
made will depend principally on the prices at which these materials may be
obtained.

page_text: What I claim is the combining the materials obtained by acting on castor
and other oil with chloride of sulphur, with cork dust, saw dust, and fibre, as
herein described.
In witness whereof, I, the said Alexander Parkes, have hereunto set my
hand and seal, this Sixth day of December, in the year of our Lord
Ono thousand eight hundred and sixty-six.
ALEXANDER PARKES. (L.B.)
