Improvements in connection with the Drawing Off and Method of
Conducting the Slivers from the Circular Combs of Noble's"
and similar Machines.
We, MICHAEL FIRTH, of Bolton Woods Shed, Bradford, in the County of York,
Machine Wool Comber, and JOSEPH ROBERTSHAW, of the same place, Combing
Overlooker, do hereby declare the nature of this invention to be as follows:-
"
The object of our invention is to obviate the liability of fibres collecting around
and forming a "lap" upon either of the drawing off rollers mounted near each small
circular comb, which "lap on coming in contact with the pins of the adjacent
comb circle, bends, breaks, or otherwise damages them to such an extent as to render
them useless for the proper and effectual clearing of the fibre: and also by our
combination to be enabled to dispense with the revolving funnels hitherto mounted
near the said drawing off rollers and near the centre of the machine by which the
several slivers are collected and combined, thereby preventing some of the fibres
being twisted around or laid across the remaining portions of the sliver thus
producing more valuable cleared fibre or top."
"
We accomplish our object in the following manner: The drawing off rollers are
mounted and operated somewhat in the usual manner, but in addition to the usual
endless apron working around one of the drawing off rollers for removing the sliver
or cleared fibre from the adjacent small comb circle, we place another endless apron
around the other roller and upon an additional stretching roller mounted near the
centre of the machine, and placed in such position so as to allow the additional
endless apron to run in contact with the other or ordinary endless apron, between
which, where in contact, the slivers from one portion of the large and from the small
circle are carried towards the centre of the machine; the other drawing off rollers
also conveying the respective slivers in a similar manner towards the centre of the
machine where they are combined.
The combined slivers drawn from the circular combs on both sides of the machine,
are thus brought together at or near the centre of the machine, and the delivery of
the said combined slivers from or near this point is effected between two endless
aprons of the series being kept in contact with the same by their respective
stretching rollers, the slivers being conveyed from between the endless aprons to, a
suitable receptacle in the ordinary manner: thus by these means dispensing with the
usual revolving funnels at or near the centre of the machine, and preventing the
fibre coming in contact with the drawing of rollers, thereby rendering it impossible
to lap around the same and damage the comb pins of the small circles.

COMPLETE SPECIFICATION.
Improvements in connection with the Drawing Off and Method of
Conducting the Slivers from the Circular Combs of "Noble's"
and similar Machines.
We, MICHAEL FIRTH, of Bolton Woods Shed, Bradford, in the County of York,
Machine Wool Comber, and JOSEPH ROBERTSHAW, of the same place, 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 :-
The object of our invention is to obviate the liability of fibres collecting around

page_text: and forming a "lap" upon either of the drawing off rollers mounted near each
small circular comb, which on coming in contact with the pins of the adjacent comb
circle, bends, breaks or otherwise damages them to such an extent as to render
them useless, for the proper and effectual clearing of the fibre: and also by our
combination to be enabled to dispense with the revolving funnels hitherto mounted
near the said drawing off rollers and near the centre of the machine, by which the
several slivers are collected and combined, thereby preventing some of the fibres being
twisted around or laid across the remaining portions of the sliver, thus producing
straighter and more valuable cleared fibre or "top."
In the drawings Fig. 1. represents a diagrain plan of the comb circles and
drawing off rollers of a Noble's" machine arranged according to our invention.
Fig. 2. is a detail plan of the four centre rollers.
Fig. 3. a sectional detail of one of the centre rollers, and
Fig. 4. detail views of an arm for traversing the additional endless aprons.
The drawing off rollers A and B. and the stretching rollers C and D. on each side
of the machine are mounted and operated somewhat in the usual manner, but in
addition to the usual endless aprons E. working around the respective drawing off
rollers B. for removing the sliver or cleared fibre from the adjacent small comb
circles F or F1 we place another endless apron G. around the other roller B. of
each pair, and upon the respective additional stretching rollers H and H2 mounted
by preference upon a circular plate J. secured near the centre of the machine.
The circular plate J. may be secured to the cross plate K. and is adjustable
thereon. The rollers H' H2 and H³ mounted to the circular plate J. are adjustable
thereon in the direction of the respective arrows, in order to admit of regulation to
suit the varying thicknesses of the endless aprons.
The rollers H and H¹ of one series and H2 and H³ of the other series, are so
placed on the circular plate J. as to allow the respective additional endless aprons G.
to run in contact with the other or ordinary aprons E. The endless aprons E and L.
run in contact as hitherto, convey in the direction of the arrows the slivers drawn
from the large circle at M. M., the slivers drawn from the small circles at N. N.
pass along with the before mentioned slivers between the aprons G and E.
towards the centre of the machine, where all are combined on passing between the
rollers H and H³.
The slivers drawn from the large and small circles and combined at or near the
centre of the machine in the manner described, may be conveyed therefrom in the
direction shown at Z. by an ordinary coiling box, thus dispensing with the usual
revolving funnels about the centre of the machine, and preventing the fibre coming
in actual contact with the drawing off rollers, thereby rendering it impossible to lap
around the same and damage the comb pins of the small circles.
The rollers upon plate J. are mounted upon a central spindle S. having a
collar P. formed thereon near the bottom somewhat larger in diameter than the
spindle, and a similar collar attached by a screw at the top. Each roller is recessed
at the end to such diameter as to correspond with the collars which form the
bearing surface, and by which arrangement, loose fibre is not so liable to lap
around the end of the rollers as is the case with rollers mounted in the ordinary
manner.
The stretching or carrying rollers of each series are mounted to the tables T. of
an ordinary traversing apparatus as hitherto, and in order that the additional endless
aprons G. may be traversed at the same time and in the same direction, we attach
to each roller bracket U. an arm V. having one end formed as at W. to embrace
the additional apron, so that on the brackets U. moving, the arms V. and endless
aprons will move likewise.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. The combination of the additional endless aprons G. with additional stretching

page_text: rollers mounted near the centre of the machine in such manner that all the slivers
are conducted thereto and delivered therefrom in the manner shown and described,
and for the purposes hereinbefore set forth.
2. The method of traversing the additional endless aprons G. by the arms V.
5 substantially as described.
