PROVISIONAL SPECIFICATION.
Improvements in the Method of and Apparatus for the Manufacture
of Yarns and Threads.
1, JAMES BOYLE, of Wood Lane, Headingley, Leeds, in the County of York,
Hemp and Yarn Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the construction of apparatus by a novel
combination of mechanism, arranged in such a manner as to enable the construction
or manufacture of a yarn or thread, in which the inside or core may be of one
kind or quality of fibre, and the outside or covering of the same or other suitable
fibre.
I accomplish my object in the following manner. Between the nip of the usual
drawing rollers of an ordinary spinning frame, the fibre for covering the centre
thread or core is passed, and in front of the said rollers, I place a second pair, one
of which is grooved to allow the covering of the core or centre thread to pass.
The centre thread or core is drawn by the second rollers from a bobbin or reel
placed in a suitable position, and as the said rollers deliver the centre thread or
core, the covering fibre passing through the groove is twisted around the centre
thread by the rotation of the spindle flyer or the like, thus combining fibres of the
same or different qualities into one thread.
Dated this 23rd day of June 1896.

Improvements in the Method of and Apparatus for the Manufacture
of Yarns and Threads.
JAMES BOYLE of Wood Lane Headingley, Leeds in the County of York
Hemp and Yarn Merchant, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This invention relates to a new method by which a thread or yarn of any given
fibre may be covered or enclosed by a coating of the same, or any other fibre, and
twisted into yarn so that the covered thread or yarn shall be in the middle of the
new product, forming as it were, a core. The figures of the drawing shew the
apparatus I employ in section and elevation respectively. In front of the present
delivery rollers A, of a flax or hemp spinning frame I place a pair of covering
rollers B, driven at the same speed and receiving the covering threads, or sliver F,
through the conical guide C. A groove, about an eighth of an inch in diameter,
is cut in the periphery of the bottom roller B to receive the yarn E, which passes

page_text: through a hole in the plate D as shewn. The sliver F also passes between these
rollers in the form of a band of threads as shewn in the elevation. The combined
yaru and sliver G is then taken up by an ordinary flyer and twisted in the
usual way.
In this way a yarn can be produced in which a core of an inferior quality of
fibre is covered by one of a superior quality.
I wish it to be understood that I do not claim generally the covering of one
thread or yarn by another but
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
The particular method of, and apparatus for, covering a thread or yarn of any
fibre with a sliver of the same or any other fibre substantially as described and
illustrated in the drawing.
JAMES BOYLE.
