IMPROVEMENTS IN MACHINERY FOR SIZEING, TARRING,. DYEING, DRYING, AND FINISHING LAID AND OTHER TWINES, LINES, YARNS,: THREADS, AND FIBRES." PROAL SPFICATION left by the said.
Year: 1868

page_text: LETTERS PATENT to. William Weldon Symington, of Chard, in the
County of Somerset, Engineer, for the Invention of "IMPROVEMENTS
IN MACHINERY FOR SIZEING, TARRING,. DYEING, DRYING, AND FINISHING
LAID AND OTHER TWINES, LINES, YARNS,: THREADS, AND FIBRES."
PROVISIONAL SPECIFICATION left by the said. William Weldon
Symington at the Office of the Commissioners of Patents, with
his Petition, on the 20th April 1868.
I, WILLIAM WELDON SYMINGTON, of Chard, in the County: of:
Somerset, Engineer, do hereby declare the nature of the said. Invention:
for "IMPROVEMENTS IN MACHINERY FOR SIZEING, TARRING, DYEING, DRYING,,
AND FINISHING LAID AND OTHER TWINES, LINES, YARNS, THREADS, AND FIBRES,"
to be as follows:-
My Invention relates; first, to improvements in revolving cylinders.
employed in drying and finishing lines,. twines, yarns, or other fibres.:
These cylinders which are hollow I make of iron, and cover the periphery
with a surface of enamel to prevent the discoloration of the yarns or
other fibres by contact with the iron, by which means I am enabled to,
use iron cylinders for the purpose of drying said yarns or fibres, thus.
effecting a great economy in the construction of the apparatus. These:

page_text: cylinders, which are four or more in number, are mounted in bearings
enclosed in a suitable chamber. The axis of each cylinder I make
hollow and connect it with a suitable steam pipe so as to heat tho.
cylinders by keeping them continually filled with steam. The yarns,
lines, or fibres after having passed through the sizeing, tarring, or dyeing
bath, are passed round these heated revolving cylinders for the purpose
of effecting the drying operation before being wound on the bobbins.
I also pass into the chamber containing the cylinders a current of heated
air direct from a furnace which further assists in drying the yarns and
prevents the condensation of the steam in the cylinders. The heated
air also prevents the condensation on the sides of the chamber of the
vapors arising from the yarn or fibres when passing over the cylinders.
In this chamber I further mount two or more brushes made preferably
of horsehair cloth, each brush revolving in contact with the twine or
fibre for the purpose of finishing the same while passing from one
cylinder to the other. I also apply revolving brushes to the peripheries
of the skimping and drudging rollers against which they rotate for the
purpose of cleansing said rollers from the deposits left by the yarn or
fibres in passing over them in the process of tarring, sizeing, or
dyeing.
My Invention further consists in enamelling the rollers used in
connection with the sizeing or other bath, by which means I am enabled
to make said rollers of iron instead of brass or other inoxydizable metal
as hitherto.
SPECIFICATION in pursuance of the conditions of the Letters Patent 2
filed by the said William Weldon Symington in the Great Seal
Patent Office on the 20th October 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WELDON SYMINGTON, of Chard, in the County of Somerset, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twentieth day of April, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said William Weldon Symington, Her special

page_text: licence that I, the said. William Weldon Symington, my executors,
administrators, and assigns, or such others as I, the said William Weldon
Symington, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times
thereafter during the term therein expressed, should and lawfully migl.t
make, use, exercise, and vend, within the United Kingdom of Great
Britain and Ireland, the Channel Islands, and Isle of Man, an Inven-
tion for "IMPROVEMENTS IN MACHINERY FOR SIZEING, TARRING, DYEING,
DRYING, AND FINISHING LAID AND OTHER TWINES, LINES, YARNS, THREADS, AND
FIBRES," upon the condition (amongst others) that I, the said William
Weldon Symington, 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 William Weldon Symington, do
hereby declare the nature of my said Invention, and in what manner
the same is to be performed, to be particularly described and ascertained
in and by the following statement, reference being had to the Sheet of
Drawings hereunto annexed and to the letters and figures marked
thereon (that is to say).:-
My Invention relates, first, to improvements in the revolving cylinders
employed in drying and finishing lines, twines, yarns, and other fibres.
These cylinders which are hollow I make of iron and cover their
periphery with a surface of enamel to prevent the discoloration of the
yarns or other fibres by contact with the iron, by which means I am
enabled to use iron cylinders for the purpose of drying said yarns or
fibres, thus effecting great economy in the construction of the apparatus.
These cylinders, which are four or more in number, are mounted in
bearings and enclosed in a suitable chamber. The axis of each cylinder
is made hollow and connected with a suitable steam pipe so as to heat
the cylinders by keeping them continually filled with steam. The yarns,
lines, or fibres after having passed through the sizeing, tarring, or dyeing
bath are passed round these heated revolving cylinders for the purpose
of effecting the drying operation before being wound on the bobbins ;
I also pass into the chamber containing the hollow cylinders a current

page_text: of cleansing the same of all deposits left by the yarn or thread in its
passage to the sizeing or tarring bath F, also provided with an enamelled
roller or rollers for conducting the fibres. The fibres after passing
through the bath are next operated on by ordinary drudging rollers G,
which I likewise provide with brushes H, H, serving to evenly distribute
and remove any excess of size or tar taken up by the threads. The
threads thus treated next pass over a guide roller or rollers (in all cases
of enamelled metal) to the drying cylinders B contained in chamber A
as before mentioned, in which they are operated on by the brushes. K
preferably of horsehair cloth, and caused to revolve in contact with the
fibres in their passage through the drying chamber for the purpose of
finishing the same. The threads or fibres are then wound on bobbins
or reels L ready for use.
Having described the nature of my Invention and the manner of
performing the same, I declare that what I claim as my Invention
to be protected by the herein-before in part recited Letters Patent is,-
1st. The use of enamelled iron cylinders for drying and finishing lines,
twines, yarns, or fibres.
2ndly. I claim introducing heated air direct from a furnace into the
chamber A containing the hollow steam drying cylinders B, as and for
the purposes described.
3rdly. I claim the application of revolving brushes to the peripheries
of the skimping and drudging rollers of machines for sizeing, tarring,
dyeing, and finishing yarns, threads, and fibres, as and for the purposes
described.
4thly. I claim the use of enamelled rollers in connection with the
tarring, sizeing, or dyeing bath of such machines, as and for the purpose
described.
In witness whereof, I, the said William Weldon Symington, have
hereunto set my hand and seal, this Twentieth day of October,
in the year of our Lord One thousand eight hundred and sixty-
eight.
W WELDON SYMINGTON. (L.S.)
