Yarns or Threads of Various Kinds.
We, ROBERT BOYD, Junior, of 53 Cochrane Street, Glasgow, in the County of
Lanark, North Britain, Merchant, and EDMOND LEPAINTEUR, of Roubaix, France,
Manufacturer, do hereby declare the nature of this Invention to be as follows, that is
to say:
This Invention has for its object to improve and simplify the construction of
machinery specially designed for twisting and winding chenille but also applicable for
twisting and winding yarns or threads of various kinds.
In carrying out the Invention in the case of chenille, the chenille being in a cut or divided
condition on a roller or beam as produced by machinery described in the Provisional
Specification relative to the Application for Letters Patent by the present Applicants
and numbered 15033 of 1886, is first wound upon large bobbins the number of ends
or strands wound on each large bobbin being the same as that of the spindlos for
small bobbins in each small machine or set to which each large bobbin is in turn
transferred. In each machine or set of spindles the spindles which are vertical are
arranged in a circle and are fixed by their bottom ends to a horizontal frame plate.
The spindles have pinions running loose on them which are in gear with and driven
by a horizontal spurwheel, and frictional disks resting on the pinions drive the bobbins
by pegs the bobbins being loose on the spindles. The horizontal spurwheel is driven
by means of bevil wheels from a horizontal first-motion shaft having on it a crank
handle for turning it by hand and also fast and loose pulleys for a driving belt. A
pinion on the first-motion shaft drives a spurwheel on a horizontal shaft having also
on it a
"heart" cam which imparts a traverse motion to a series of guide eyes through
which the chenille strands are led to the small bobbins, the large bobbin being carried
above, and the strands proceeding down from it to a central guide and thence to the
traversing guide eyes which are all upon a ring or frame moved up and down by the
heart cam.
When the contents of a large bobbin have been wound on a set of small bobbins
the large bobbin is removed and a reel is placed in suitable supports over the set o

page_text: spindles. This reel is driven by means of a pitch chain and toothed gearing so as to
rotate in concert with the bobbins below, and the strands are led up through suitably
placed guide eyes from the bobbins to the reel on which they are wound in hanks.
The strands of chenille or the other yarns or threads are twisted as they pass from
the bobbins to the reel the degree of twist depending on the relative speeds of the
several parts.
Instead of first rewinding the chenille from a beam or roller on to large bobbins,
a set of such bobbins may be placed on a shaft in the loom and may have the chenille
wound directly upon them as it is produced.
The spindles may be made tubular and yarns or threads may be led up through
them so as to become combined with the yarns or threads passing from the bobbins.

page_text: Yarns or Threads of Various Kinds.
We, ROBERT BOYD, Junior, of 53 Cochrane Street, Glasgow, in the County of
Lanark, North Britain, Merchant, and EDMOND LEPAINTEUR, of Roubaix, France,
Manufacturer, 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, that is to say :-
This Invention has for its object to improve and simplify the construction of
machinery specially designed for twisting and winding chenille but also applicable for
twisting and winding yarns or threads of various kinds.
In carrying out the Invention in the case of chenille, the chenille being in a cut or
divided condition on a roller or beam as produced by machinery described in our
Patent Specification No. 15033 of 1886, is first wound upon large bobbins the number
of ends or strands wound on each large bobbin being the same as that of the spindles
for small bobbins in each small machine or set to which each large bobbin is in turn
transferred.
When the contents of a large bobbin have been wound on a set of small bobbins
the large bobbin is replaced by a reel on which the strands from the small bobbins aro
wound in hanks.
Instead of first rewinding the chenille from a beam or roller on to large bobbins, a
set of such bobbins may be placed on a shaft in the loom and may have the chenille
wound directly upon them as it is produced.
And in order that the said Invention and.the manner of performing the same may
be properly understood we hereunto append a sheet of explanatory drawings to be
hereinafter referred to and showing the two arrangements of the machine; figure, 1,
being a sectional elevation of the machine as arranged for winding the chenille off the
large bobbin and figure, 2, an elevation of the machine as arranged for twisting and
rewinding the chenille into hanks.
In the machine spindles, 3, for the small bobbins, 4, are vertical and arranged in a
circle, being fixed by their bottom ends to a horizontal frame plate, 5, of an annular
form. The spindles, 3, have pinions, 6, running loose on them and which are in gear
with and driven by a horizontal spurwheel, 7, which is carried and guided by the
plate, 5. Frictional disks, 8, resting on the pinions, 6, drive the bobbins, 4, by pegs
the bobbins being loose on the spindles, 3. The horizontal spurwheel, 7, is driven
by means of a pair of bevil wheels, 9, from a horizontal first-motion shaft, 10, having
on it a crank handle, 11, for turning it by hand and also fast and loose pulleys, 12,
for a driving belt. A pinion, 13, on the first-motion shaft, 10, drives a spurwheel, 14,
on a lower horizontal shaft, 15, having on its inner end a. heart"
cam, 16, which in
the machine shown in figure, 1, imparts a traverse motion to a series of guide eyes
through which the chenille strands are led to the bobbins, 4, by acting on an anti-
friction roller fitted in the lower end of a vertical spindle, 17. The guide eyes are
"

page_text: fixed in a ring or disk, 18, formed or fixed near the upper end of the spindle, 17.
The large bobbin, 19, is carried above by a standard, 20; fixed to the plate, 5, and
the strands proceed down from it to a central guide, 21, also carried by the
standard, 20, and thence through the guide eyes to the bobbins, 4.
In the machine arranged as shown in figure, 2, of the drawings the large
bobbin, 19, and guide eye, 21, are removed and a reel, 22, is placed in bearings
near the upper ends of standards, 23, so as to bo over the set of spindles, 3. The
reel, 22, is driven by gearing consisting of a pinion, 24, on the horizontal shaft, 15,
which gears with a spurwhool, 25, loose on the shaft, 10, this spurwheel, 25, acting
through sprocket wheels, 26, 27, and a pitch chain, 28, on pinions, 29, 30, the upper
one, 30, being fixed on the outer end of the spindle of the reel, 22, so that the reel
rotates in concert with the bobbins, 4, below. The pinion, 24, is made capable of
being thrown out of gear when the machine is to be used as shown in figure, 1.
There are provided two sets of guide eves up through which the strands are led to the
reel, 22. The lower guide eyes are fixed in a ring or disk, 31, fixed on the upper end
of the spindle, 17, which in this case is not acted on by the heart cam, 16, being held
up so that the cam, 16, cannot act on the antifriction roller as hereinbefore described,
by a catch piece, 32, inserted beneath its bottom end this catch piece being carried on
a small bracket, 33, fixed to one of the lower standards, 34, of the machine. The
upper guide eyes are fixed in a horizontal bar, 35, carried by the standards, 23, and
the strands are led up through these two sets of guide eyes from the bobbins, 4, to the
reel, 22, on which they are wound in hanks. The strands of chenille or the other
yarns or threads are twisted as they pass from the bobbins to the reel the degree
of twist depending on the relative speeds of the bobbins, 4, and of the reel, 22.
The spindles, 3, may be made tubular and yarns or threads may be led up through
them so as to become combined with the yarns or threads passing from the
bobbins, 4.
Having now particularly described and ascertained the nature of the said Invention
and in what manner the same is to be performed we declare that what we claim
is :-
1.―The combination and arrangement of parts of machinery for winding chenille
or yarns or threads of various kinds substantially as hereinbefore describod with
reference to figure, 1, of the accompanying drawings.
2. The combination and arrangement of parts of machinery for twisting chenille
or yarns or threads of various kinds and winding them into banks, substantially as
hereinbefore described with reference to figure, 2, of the accompanying drawings.
3. In twisting and winding machinery of the kind hereinbefore described making
the bobbin spindles tubular substantially as and for the purpose hereinbefore
described.
