PROVISIONAL SPECIFICATION.
Improvements in "Noble's" Combing Machines.
We, WILLIAM HORSFALL GREENWOOD, Commission Wool Comber, and
FREDERICK FARRAR, Manager, both of Upper Castle Street, Bradford in
the County of York, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in "Noble's" combing machines for
combing fibrous material. A defect in this machine is that short or transversely
disposed fibres, and burrs, shives or neps are liable to be fed into the machine
exactly between the combs and are therefore drawn off into the sliver practically
without being combed. The said improvements consist in passing or combing the
root of the fringe of fibres through a supplementary comb, to remedy this defect,
as the fibres are drawn off.
For this purpose we employ a radial comb having one or more annular rows of
radial pins projecting from its periphery. This comb is mounted so as to revolve
freely and is so arranged that its pins penetrate the fringe and intersect the fibres
between the drawing off rollers and the comb. A guide or rest is provided to
support the fringe of fibres and prevent it being displaced as the pins of the
radial comb penetrate it. By this arrangement all the irregularly disposed fibres
not held by the circular comb are either held back by the radial comb or they are
combed and straightened out by it as the root of the fringe is drawn through such
comb and burrs, shives, and neps are also prevented from being drawn into the
gliver.
We find these radial combs are most useful in conjunction with the drawing off
rollers of the large circle of a "Noble's "comb but they may be advantageously
applied to the drawing off rollers of the small circles also.
The said combs are preferably made with two rows of pins arranged at such an
angle to each other that the points of both rows of pins approximately lie in the
same plane. And the points of one row of pins are arranged to project more or less
beyond the other row so that the comb may more easily penetrate the fringe.

COMPLETE SPECIFICATION.
Improvements in "Noble's" Combing Machines.
We, WILLIAM HORSFALL GREENWOOD, Commission Wool Comber, and
FREDERICK FARRAR, Manager, both of Upper Castle Street, Bradford, in
the County of York, 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 improvements in "Noble's" combing machines for
combing fibrous material. A defect in this machine is that short or transversely
disposed fibres, and burrs, shives, or neps are liable to be fed into the machine
exactly between the combs and are therefore drawn off into the sliver practically
without being combed. The said improvements consist in passing or combing the
root of the fringe of fibres through a supplementary comb, to remedy this defect,
as the fibres are drawn off.
For this purpose we employ a radial comb having one or more annular rows of

page_text: radial pins projecting from its periphery. This comb is mounted so as to revolve
freely and is so arranged that its pins penetrate the fringe and intersect the fibres
between the drawing off rollers and the comb. By this arrangement all the
irregularly disposed fibres not held by the circular comb are either held back by
the radial comb' or they are combed and straightened out by it as the root of the
fringe is drawn through such comb. And burrs, shives, and neps are also prevented
from being drawn into the sliver as they cannot pass the radial comb but remain on
the short fringe of fibres left projecting from the circle and are eventually dabbed
between the pins of one of the other circles.

Reference is made to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference distinguish the same parts in
both figures.
Figure 1, represents a side view of a portion of a large circle of a combing
machine and such other parts as are necessary to fully illustrate the application of
our improvements thereto.
Figure 2, is a plan view of the same with the radial comb and drawing off rollers
shown in section.
The radial comb A is loosely mounted on the stud R carried by the arm C
projecting from the feed knife bracket D. And the pins E of the said comb pass
down between the pins F of the large circle G and the drawing-off rollers H. The
side faces of the comb A are preferably recessed to partly receive the head J of the
stud B and the washer K mounted thereon so as to more perfectly exclude dust,
short fibres and other foreign matter:
•
"[
The pins E of the comb A are preferably secured in the brass facing L represented
in section by the black part Figure 2 and such facing is secured to A by three or
more screws similar to a Figure 2.
"
The comb A is preferably made with two rows of pins more or less inclined
towards the drawing-off rollers and arranged at such an angle to each other that
the points of both rows of pins intersect or approximately lie in the same plane.
And the points of one row of pins may be arranged to project more or less beyond
the other row so that the comb may more easily penetrate the fringe.
We find these radial combs are more useful in conjunction with the drawing off
rollers of the large circle of a "Noble's "comb but we may also apply them to the
drawing-off rollers of the small circle.
3
A thin guard or rest secured to the steam chest or other convenient part may be
provided to pass up by the side of the drawing-off rollers approximately to the
level of the underside of the fringe of the fibres and thus prevent such fringe being
displaced as the pins of the radial comb penetrate it.
Having now particularly described and ascertained the nature of our said.inven-
tion, and in what manner the same is to be performed, we declare what we
claim is :
The combination with a "Noble's" comb, of a radial comb mounted between
the drawing-off rollers and any of the comb. circles,. substantially, as herein shown
and described and for the purpose specified.
