Ickringill Spinners all of Keighley in the County of York, for an Invention
of IMPROVEMENTS IN COMBING MACHINES
PROVISIONAL SPECIFICATION left by the said Charles Hoyle, Ira Ickringill
& James Ickringill at the Office of the Commissioners of Patents on the
9th October 1883.
CHARLES HOYLE, Machine Maker, IRA ICKRINGILL, and JAMES ICKRINGILL,
Spinners, all of Keighley in the County of York. IMPROVEMENTS IN COMBING
MACHINES.
The object of this invention is to draw off from the circle of a Listers' comb, two
tops of such length of staple as will better suit the present requirements of the
worsted trade; in addition to the hitherto "milking" drawing off rollers.
Both the tops are drawn off by a pair of vertical fluted rollers and a pair of press
rollers also vertical with the revolving funnel between, the regulation of the fluted
or drawing off rollers regulates the length of staple.
The first top drawn off is of the very longest staple, the second of a shorter staple,
both these tops are passed to the gill boxes but the result of the third drawing off
or "milking" as it is termed, requires to be carded again. The noil is drawn off
in the ordinary manner, but under our improved method the noil produced is
considerably less in quantity than hitherto.
The first top drawn off contains not only the longest staple, but the most
lustrous wool and is used for genappe, and heald yarns, also for worsted warps
now so much in demand, whilst the second lot contains the short stapled and less
lustrous wool, and is then more suitable for Hosiery yarn for which purpose it is
thus prepared.
In mohair, camel hair, and other similar fibres, the long and short staple is
separated in the process of sorting.
By the use of our improvement, this mode of separating the long staple from the
short is unnecessary, as our improvements separate the long from the short in the
process of combing. In the case of mohair the tops free from kemp are more
valuable than those containing kemps: in our process the first top drawn off
contains no kemp whatever, the kemp being all in the second top.

SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said Charles Hoyle, Ira Ickringill & James Ickringill in the Patent Office
on the 8th April 1884.

The object of this invention is to draw off from the circle of a
combing machine two or more slivers of such length of fibre or staple as will better
suit the requirements of the worsted trade, in addition, to the hitherto "milking
drawing off rollers; and consists in mounting two or more sets of vertical drawing
off rollers placed at different distances from the circumference of the comb circle,
by which fibre of different lengths is drawn from the said circle.
In order that our invention may be better understood, we have appended a
drawing which represents a diagram plan of such portions of
"Listers" combing
machine as are required to make clear our invention.
a
The wool or other fibrous substance to be combed is fed to the teeth of the
comb circle A in the ordinary manner, which revolves in the direction of the
arrow 1, and the noil is removed from the circle as in machines of the ordinary
construction.
•
On one side of the machine we mount a number of pairs of vertical rollers, the
first pair of fluted drawing off rollers B, B, nearest the feeding head or nip of the
comb are at the greatest distance from the comb circle A, and draw off the very
longest staple from the same; between the vertical fluted rollers B, B, and the
vertical press rollera C, C, we mount a revolving funnel D, which receives motion
by a belt from pulley P, mounted on a vertical shaft E. The fibre after passing
between the fluted rollers B, B, passes through the funnel D, and between the press
rollers C, C, and finally through the guide box F to the sliver can. Between the
fluted rollers B, B, and the next pair of vertical fluted rollers B', B¹, we place a
revolving fan G which revolves in the direction of the curved arrow 2, and diverts
the fibre forming the "beard" from the direction indicated by the lines H, to a
more favourable direction as shewn by lines J for being gathered into the nip of
the second pair of fluted rollers B³, B¹, which we place nearer to the comb circle A
than those first mentioned, and which draw off the short stapled fibre left in the
circle by the first pair of drawing off rollers B, B. We also place a revolving
funnel D¹ between the fluted rollers B', B¹, and press rollers C₁, C, all these, and
the rollers before described, are secured to vertical spindles, and driven by gearing
secured near the bottom of the spindles in the same manner as the drawing off
rollers in "Nobles" combing machines.
The first sliver that is drawn off contains not only the longest staple, but most
lustrous, and may be used for genappe and heald yarns, and for worsted warps, whilst
the second sliver drawn off by the rollers B¹, B¹, contains the short stapled and
less lustrous fibre, and is then more suitable for hosiery yarn for which it is
prepared.
In mohair, camel hair, and other similar fibres, the long and the short fibre is
separated by hand labour in the process of sorting; but by the use of our improved
method of drawing off, this mode of separating the long fibre from the short is
rendered unnecessary, as the machine separates the long from the short in the
process of combing in the manner as before described.
In the case of mohair, the sliver first taken from the machine containing the long
fibre is comparatively free from kemps, nearly all the kemps being in the second or
short stapled sliver.

page_text: When three or more sets of drawing off rollers are fitted to a combing machine,
we mount and actuate the rollers and funnels in a similar manner to that before
described, and in every case the vertical fluted rollers from the first pair near to
the feeding head, to the last pair near to the noil stripping plates, are placed at
gradually varying distances from the comb circle A, those rollers next to the
feeding head being the furthest, and those next to the noil stripping plates nearest to
the comb circle, thereby drawing off fibre of varying lengths corresponding with
the varying distances at which the drawing off rollers are placed from the comb
circle.
In the drawing, the brackets for supporting the upper portion of each pair of
rollers are removed in order to more clearly shew the rollers, and are of the same
construction as the brackets H¹ which support the bottom portion of the roller
spindles.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is:-
The mounting of two or more sets of vertical drawing off rollers placed at
different distances from the comb circle for drawing the fibre from the circle and
separating the long from the short, delivering it in separate slivers substantially in
the manner described.
In Witness whereof I the said Ira Ickringill for and on behalf of myself and
the said Charles Hoyle and James Ickringill have hereunto set my hand and seal
this seventh day of April in the year of our Lord, one thousand eight hundred and
eighty four.
