page_text: LETTERS PATENT to Charles Loxton Jackson of Bolton in the County of
Lancaster, for an Invention of "IMPROVEMENTS IN THE MANUFacture of
BOWLS OR BOLLERS FOR MANGLING AND CALENDERING MACHINES EMPLOYED
PROVISIONAL SPECIFICATION left by the said Charles Loxton Jackson at
the Office of the Commissioners of Patents on the 15th January 1883.
CHARLES LOXTON JACKSON of Bolton in the County of Lancaster " IMPROVE-
MENTS IN THE MANUFACTURE OF BOWLS OR ROLLERS FOR MANGLING AND.
CALENDERING MACHINES EMPLOYED IN FINISHING WOVEN FABRICS AND PAPER
The principal object of this invention is to manufacture bowls or rollers
peculiarly suitable for finishing woven fabrics made from jute fibre, but the
improved bowls or rollers may also be used with advantage in finishing other kinds
of woven fabrics, paper or other material requiring calendering.
The principal feature of my invention consists in the use for this purpose of
prepared jute fibre (either by itself or in combination with other fibrous
substances) a material which has not hitherto been employed for this purposo,
but which is more especially suited for finishing woven fabrics made from the same
fibre.
I propose to open "willow" card or comb the jute fibre, and cleanse or purify the
same from all extraneous matter, and with the jute fibre thus prepared either alone
or mixed with other fibrous material as above stated I proceed to build up a bowl
or roller (in the manner now practised in forming bowls or rollers from cotton,
wool or other similar materials) upon a wrought iron or steel axis.
The bowls or rollers after being thus built up of the prepared jute fibre are
submitted to powerful hydraulic pressure until they become perfectly hard and
solid after which they are turned up to a true cylindrical form and polished in a
lathe, and are then ready for use in machines for mangling and calendering jute
and other woven fabrics, paper or other material requiring calendering.

the said Charles Loxton Jackson in the Great Seal Patent Office on the
13th July 1883.
CHARLES LOXTON JACKSON of Bolton in the County of Lancaster IMPROVE-
MENTS IN THE MANUFACTURE OF BOWLS OR ROLLERS FOR MANGLING AND
CALENDERING MACHINES EMPLOYED IN FINISHING WOVEN FABRICS AND PAPER
The principal object of this invention is to supersede the use of sycamore wood,
paper, compressed cotton and other materials hitherto employed for this purpose,
and to manufacture bowls or rollers more peculiarly suitable for mangling
calendering and finishing woven fabrics made from jute fibre, but the improved
bowls or rollers may also be used with advantage in mangling calondering and
finishing other kinds of woven fabrics, paper, or other material or materials
requiring to be calendered.
The principal novel feature of my invention consists in the use for this purpose
of prepared jute fibre (either by itself or in combination with other fibrous
substances) a material which has not hitherto been employed for this purpose, but
which is more especially suited for calendering and finishing woven fabrics made
from the same fibre.
In manufacturing calendering bowls or rollers according to my invention I
propose to open "willow" card or comb the jute fibre and to cleanse or purify the
same from all extraneous matter and with the jute fibre thus prepared (either
alone or mixed with other fibrous materials as above stated) I proceed to build up
a bowl or roller (in the manner now practised in forming bowls or rollers froin
cotton, wool, or other similar materials) upon a wrought iron or steel axis.
The bowls or rollers, after being thus built up of the prepared jute fibre, are
then submitted to powerful hydraulic pressure until they become perfectly hard
and solid, after which they are put in a lathe and turned up to a true cylindrical
form and polished. They are then ready for use in machines for mangling
calendering and finishing jute and other woven fabrics, paper or other material
requiring to be calendered.
"
Having now described the nature and object of my said invention for
Improvements in the manufacture of bowls or rollers for mangling and calendering
machines employed in finishing woven fabrics and paper together with the
manner in which the same may be performed or carried into practical effect, I
would remark in conclusion that I claim as my invention the manufacture of bowls
or rollers for such purposes from prepared and compressed jute fibre (either alone
or in combination with other fibrous substances) substantially as hereinbefore more
particularly set forth and described
In witness, whereof I the said Charles Loxton Jackson. have hereunto set
my hand and seal this eleventh day of July in the year of our Lord one
thousand eight hundred and Eighty three
