Year: 1876

page_text: LETTERS PATENT to Henry Edward Newton, of the Office for Patents, 66,
Chancery Lane, in the County of Middlesex, Civil Engineer, for the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF THREADS OR YARNS." A com-
munication from abroad by François Delamare Deboutteville, the Younger, of
Paris, in the Republic of France.
Sealed the 9th September 1876, and dated the 21st April 1876.
PROVISIONAL SPECIFICATION left by the said Henry Edward Newton at
the Office of the Commissioners of Patents on the 21st April 1876.
HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer. "IMPROVEMENTS IN THE MANUFACTURE OF
THREADS OR YARNS."
This Invention consists in subjecting the spun threads of cotton and other fibres
to a rubbing action as they issue from the spinning frame, or after they have been
submitted to the dye bath, or even after they have been doubled and twisted, the
object being to provide a substitute for the gassing operation, by causing the ends
of the fibres forming the threads to be worked up into the body of the threads or
yarns.
The object may be conveniently attained by passing cotton threads under the
pressure of a travelling apron and a leather covered roller, to both of which a slight
endway motion in opposite directions is given.
As the threads pass between these rotating pressing surfaces they will become
condensed into round cords, all loose or outstanding ends of fibres being by the
friction to which the threads are exposed worked into the body of the thread or
yarn.

HENRY EDWARD NEWTON, of the Office for Patents, 66, Chancery Lane, in the
County of Middlesex, Civil Engineer. "IMPROVEMENTS IN THE MANUFACTURE OF
THREADS OR YARNS." A coinmunication from abroad by Francois Delamare
Deboutteville, the Younger, of Paris, in the Republic of France.
This Invention consists in subjecting the spun threads of cotton and other fibres
to a rubbing action as they issue from the spinning frame, or after they have been
submitted to the dye bath, or even after they have been doubled and twisted, the
object being to provide a substitute for the gassing operation by causing the ends
of the fibres forming the threads to be worked up into the body of the threads or
yarns.
This object may be conveniently attained by submitting the threads, whether of
cotton, flax, wool, silk, or other fibre, to the action of frictional apparatus (rota-
frotteur) similar to that used for condensing the soft slivers or ropings delivered
from carding engines. The spun threads (arranged at a suitable distance apart to
prevent adjacent threads from uniting) are passed between a travelling endless
apron and a leather covered pressing roller, to one or both of which a slight lateral
or endway motion in opposite directions is given.
As the threads pass between these rotating pressing surfaces they will become
condensed into round cords, all loose or outstanding ends of fibres being by the
friction to which the threads are exposed worked into the body of the thread or
yarn. By this means a much stronger round thread or yarn is obtained than by
the gassing operation, as no portion of the fibres which compose the thread are
removed.
The threads or yarns after undergoing the rubbing operation may be wound on to
bobbins or reels, or may be made up in any other suitable manner.
"
Having now set forth the nature of this Invention of "Improvements in the
Manufacture of Threads or Yarns as communicated to me by my foreign corre-
spondent, and explained the manner of carrying the same into effect, I wish it to be
understood that I do not limit myself to the use of any particular arrangement of
frictional apparatus, but propose to employ any approved machine that will give
the thread the rolling and travelling motion desired; under the above in part
recited Letters Patent I therefore claim, subjecting the spun threads or yarns of
cotton, flax, wool, silk, and other fibres to a rubbing action as and for the purpose
herein set forth.
In witness whereof, I, the said Henry Edward Newton, have hereunto set my
hand and seal, the Twentieth day of October, in the year of our Lord One
thousand eight hundred and seventy-six.
