An Improvement in or applicable to Machinery for Combing Fibres.
I PERCY ASHWORTH, of the Firm of John Ashworth Limited, of Astley Bridge,
near Bolton, in the County of Lancaster, Cotton Spinner, do hereby declare the
nature of this invention to be as follows:
The object of this invention is to prevent the cutting of the fibres by the top
detaching roller of a combing machine, such cutting being liable to take place if
the machine is run at a high speed.
I have found that this cutting is occasioned by the flutes of the top detaching
roller which is heavy and is driven by the steel detaching roller, the combed
sliver of fibre being nipped firmly between these two fluted rollers.
My invention consists in dispensing with the ordinary top detaching roller,
which is usually made of steel, br brass-covered, and is therefore somewhat
expensive, and I substitute therefore a light plain surfaced top roller made of
wood or hollow metal and preferably covered with leather, cloth, or other similar
and suitable material. This light roller will be more easily rotated than a heavy
roller, and in order to obtain the necessary nip between this top detaching roller
and the steel detaching roller, I apply the desired pressure by weights or springs
acting upon the journals of the said top roller.
I find that the use of these improved top detaching rollers will enable the
machine to be run at a higher speed than was before possible without cutting
the combed fibres, and the said rollers will be much less expensive to make than
the old steel or brass covered fluted rollers.

COMPLETE SPECIFICATION.
An Improvement in or applicable to Machinery for Combing Fibres.
I PERCY ASHWORTH, of the Firm of John Ashworth Limited, of Astley Bridge,
near Bolton, in the County of Lancaster, Cotton Spinner, 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:-
The eject of this invention is to prevent the cutting of the fibres by the top
detaching roller of a combing machine, such cutting being liable to take place if
the machine is run at a high speed.
I have found that this cutting is occasioned by the flutes of the top detaching

page_text: roller, the combed sliver of fibre being nipped firmly between these two fluted
rollers.
My invention consists principally in dispensing with the ordinary fluted top
detaching roller, which is usually made of steel, or brass-covered, and is therefore
somewhat expensive, and in substituting therefor a light plain-surfaced top
roller, made of wood or thin hollow metal, and preferably covered with leather,
cloth, or other similar and suitable material.
The manner in which my said invention is to be performed or carried into
practical effect will be readily understood on reference to the sheet of drawings
hereunto annexed and the following explanation there of.
Fig. 1 on the drawing is a partial sectional elevation of so much of a combing
machine as is necessary to illustrate my invention one form of which is shown as
applied thereto, and Fig. 2 is a similar view showing a slight modification
thereof.
a is part of the combing cylinder, the top comb, c the leather covered
detaching roller, and d the bottom steel roller which is fluted as usual, e is the
horse-tail" and f the bracket for supporting the same.

I dispense (as before stated) with the ordinary heavy fluted top detaching
roller, and I substitute therefor a light plain surfaced roller g which is made of
wood or thin hollow metal and preferably covered with leather, cloth, or other
similar and suitable material. In either case these rollers may either be made
with a metal shaft extending through from end to end, or they may be provided
with metal pivots only at each end. This light roller will be more easily
rotated than a heavy roller and in order to obtain the necessary "nip" between
this top detaching roller g and the fluted steel bottom detaching roller d I apply
the desired pressure by means of either a weight (or weights) h supported by a
cord passing through a hole drilled in the "horse tail" e between the fulcrum ex
and the top detaching roller gas shown at Fig. 1, or by means of a spring
applied to the "horse-tail" e outside the said fulcrum as shown at Fig. 2, or the
weight or spring may be otherwise applied to the journals of the top detaching
roller, or in some cases may be dispensed with.
I find that the use of these improved light top-detaching rollers, will enable
the machine to be run at a higher speed than was before possible without cutting
the combed fibres, and the said rollers will be much less expensive to make than
the old heavy steel or brass-covered fluted rollers hitherto employed, and thus a
considerable economy both in time and material will be effected and the yarn
produced will have a much better appearance."
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is
.

P
In combing machines dispensing with the ordinary heavy fluted top detaching
roller, and combining with the usual leather detaching roller, and the bottom
steel fluted roller, a plain top detaching roller made of wood or hollow metal, and
covered with cloth, leather or other suitable material, substantially as herein-
before described and illustrated by the drawings annexed.
