PROVISIONAL SPECIFICATION.
Improvements in the Drawing-off Rollers of Noble's Combing
Machines.
We, EDWIN GAUNT, of Grangefield Mill, Stanningley, in the County of York,
Spinner and Manufacturer, WILLIAM HENRY COCKCROFT, of Victoria Terrace,
Stanningley, aforesaid, Combing Overlooker, and SAMUEL BEST, of Gladstone
Terrace, Stanningley, aforesaid, Combing Overlooker, do hereby declare the nature
of this invention to be as follows:-
:-
This invention relates to improvements in the drawing-off rollers of Noble's
combing machines and its object is to more thoroughly draw off the long fibres or
reduce the proportion of noil.
For this purpose in addition to the ordinary pair of drawing-off rollers we employ
a third roller of smaller diameter placed as close to the comb circle as possible and.
approximately midway between the ordinary rollers arranged just to clear one
roller and be as closely in contact with the other roller as the leather passing round
it will permit so that there is a decided pressure between them approximately equal
to that between the ordinary rollers.
This third roller is fluted in the ordinary way and is mounted at each end
preferably in adjustable bearings formed in the brackets supporting the ordinary
rollers. The third roller is also preferably driven by gearing.

Improvements in the Drawing-off Rollers of Noble's Combing
Machines.
We, EDWIN GAUNT, of Grangefield Mill, Stanningley, in the County of York,
Spinner and Manufacturer, WILLIAM HENRY COCKCROFT, of Victoria Terrace,
Stanningley, aforesaid, Combing Overlooker and SAMUEL BEST, of Gladstone
Terrace, Stanningley, aforesaid, Combing Overlooker, 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 the drawing-off rollers of Noble's
combing machines and its object is to more thoroughly draw off the long fibres and
thereby reduce the proportion of noil.
For this purpose in addition to the ordinary pair of drawing-off rollers we employ
a third roller preferably of smaller diameter placed as close to the comb circle as
possible and approximately midway between the ordinary rollers and arranged just
to clear one ordinary roller and be as closely in contact with the other ordinary
roller as the leather passing round it will permit so that there is a decided pressure
between them approximately equal to that between the ordinary rollers.
This third roller is fluted and is mounted at each end in adjustable bearings
formed in the brackets supporting the ordinary rollers and it is driven by gearing
therefrom.
Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents a plan view of such parts of a Noble's comb as are necessary

page_text: to illustrate the application of one set of rollers thereto which are shown in section
and arranged in accordance with our invention.
Figure 2, is an elevation of the set of rollers on a larger scale with a sectional
view of the comb circle on the broken line a, b Figure 1.
Figure 3, is a separate plan view of a set of rollers with the bracket etcetera in
which they are mounted.
Figure 4, is an elevation of the same approximately at right angles to
Figure 2.
Figure 5, is a separate sectional-plan view of the rollers on a larger scale with a
portion of the leather or apron Z between them.
The rollers A, A' are of the ordinary type and are mounted in the brackets B, B1
in the usual way excepting that A is not quite in line with the adjustment
screws B. The parts B and B₁ are connected together as usual by the vertical
piece C, and B' is adjustably secured by the screw bolt D to the projection E on
the box bracket F secured to the underside of the steam chest G. The rollers A, A¹
are driven as usual by the wheel H secured to the spindle J of the roller A below
the bottom plate K of the comb.
The third roller L is of smaller diameter and is mounted in the bearings M
provided in B and B' and adjusted by the screws N, N in relation to the roller A
This roller L is positively driven by the spur wheel O fixed upon the spindle J and
connected by the double stud wheel P to the pinion R fixed on the lower end of the
spindle or arbor S of the roller L. The double stud wheel P is mounted upon the
stud or upright T secured to K.
The rollers are so arranged in relation to the comb circle W that they form a
sort of double nip. The first nip being formed between the rollers L and A'
closer to the comb circle than usual and the second nip between A and A' further
from the circle. By this means the shortest of the long fibres as well as the long
fibres which only slightly project from the comb circle are laid hold of by the first
nip and are drawn off this being facilitated owing to the bulk of the fibres being
also held by the second nip.
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 that what we
claim is:
In a Noble's combing machine, the combination with the drawing-off rollers A
and A¹ of a third roller L mounted in bearings at each end and positively driven
by gearing, substantially as herein shown and described and illustrated in the
accompanying drawings.
