Year: 1865

page_text: LETTERS PATENT to John Ingham, of Bradford, in the County of York,
Dyer and Finisher, and John Culpan, of the. same. Place, Cashier, for
the Invention of "IMPROVEMENTS IN THE TREATING OF CHINA GRASS OR
OTHER VEGETABLE FIBROUS SUBSTANCES."
Sealed the 13th February 1866, and dated the 16th August 1865.
PROVISIONAL SPECIFICATION left by the said John Ingham and
John Culpan at the Office of the Commissioners of Patents, with their..
Petition, on the 16th August 1865.
We, JOHN INGHAM, of Bradford, in the County of York, Dyer and Finisher,
and JOHN CULPAN, of the same Place, Cashier, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN THE TREATING OF CHINA GRASS OR
OTHER VEGETABLE FIBROUS SUBSTANCES," to be as follows:-
This Invention relates to means or method of finishing or treating china
grass or other fibrous substances after they have undergone the ordinary
process of bleaching, so as to obtain the most perfect development of the fibre.
The fibre is first washed in a hot bath of water with a suitable quantity of dis-
solved soap, and gallipoli or other oil. The water is then extracted as much
as possible by the means of a hydro-extractor. It is then passed betwixt a

page_text: pair of squeezing rollers, and afterwards thoroughly dried by any suitable
drying means. It is made up into moderate sized bundles, and boiled seven
or eight hours in clean water, after which the fibre is placed again in the
hydro-extractor and operated upon until as much of the water is extracted as
possible; it is then again washed in hot water with soap and oil, and the
water taken out as before stated. The fibre is then passed betwixt squeezing
rollers, and thoroughly dried by any suitable drying means. If there should
still be found the objectionable hard ends, boil again in hot water with soap
and oil, squeeze and dry as before directed, and the result will be found
satisfactory.

page_text: NOW KNOW YE, that we, the said John Ingham and John Culpan,
do hereby declare the nature of our said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained in
and by the following statement (that is to say):-
This Invention relates to the means or method of treating or finishing china
grass or other vegetable fibrous substance after it has undergone the ordinary
process of bleaching, so as to obtain the most perfect development of the fibre,
or to remove all "hard ends," or gummy matters therefrom. The said fibrous
substance is first washed in a bath of hot water, with a suitable quantity of
dissolved soap and gallipoli, or other oil. The water is then extracted as
much as possible by means of a hydro-extractor. It is then passed betwixt a
pair of squeezing rollers, and afterwards thoroughly dried by any suitable
drying means. It is then made up into moderate sized bundles, and boiled
seven or eight hours in clean water, after which the fibre is again placed in
the hydro-extractor, and operated upon until as much of the water is extracted
as possible. It is then again washed in hot water with soap and oil, and the
water taken out as before stated. The fibre is then passed betwixt the
squeezing rollers, and thoroughly dried by any suitable drying means. If there
should still be found the objectionable "hard ends," boil again in hot water
with soap and oil, squeeze and dry as before directed, and the result will be
found satisfactory.
In witness whereof, I, the said John Culpan, for and on behalf of
myself and the said John Ingham, have hereunto set my hand and
seal, this Thirteenth day of February, One thousand eight hundred
and sixty-six.
JOHN CULPAN. (L.S.)-
