PROVISIONAL SPECIFICATION.
Improvements in Means for Preventing Fibres from Wrapping the
Drawing-off Rollers of Combing Machines.
We, JoHN LITTLE HALLIDAY, of Cragg Mills, Shipley, in the County of
York, Wool Comber, and LEWIS SHORE, of the same place, Overlooker, do hereby
declare the nature of this invention to be as follows, that is to say :-
Our invention relates to improvements in means for preventing fibres from
wrapping the drawing-off rollers of combing machines, having more especial
reference to the rollers used in connection with those machines known as
"Noble's Combs," and consists of the construction and arrangement of means
whereby the said wrapping of the drawing-off rollers is entirely prevented thus the
damages to the comb and the loss of time accruing from such undesirable occurrences
are entirely avoided.
This object we attain in accordance with this our invention by mounting a
supplementary roller in such a position as to be in suitable proximity with the bare
or uncovered drawing-off roller and imparting motion to this supplementary roller
(preferably by gearing from the wheel upon which the comb is mounted) so as to
cause it to revolve in the same direction and at about the same rate of speed as
said drawing-off roller is rotated.
The outer or peripheral surface of the supplementary roller is preferably formed
of "roller-cloth" and by the bearances upon which it is mounted being made
adjustable, this roller may be and preferably is adjusted in position for its outer
surface to rub against the outer surface or outer edges of the ridges or flutings
formed on the drawing-off roller above described.
Now since the two rollers, that is, the supplementary roller and this one of the
drawing-off rollers, revolve in the same direction which means that at the point or
line of contact with each other they are travelling in opposite directions it follows
that any fibre that might tend to wrap or encircle the drawing-off roller, is rubbed,
forced or impelled in a contrary direction from doing so, by the supplementary
roller which also aids its (i.e. the fibre forming part of the sliver) passage in the
proper direction after having thus prevented it from wrapping as above described,
and so the object desired is attained.
The covering of the supplementary roller is preferably effected by attaching one
end of a strip of roller cloth to at or near one end of the roller and winding said
cloth spirally around said roller finally attaching the other end of said cloth to at
or near the other end of said roller, by which means said covering of cloth is rendered
less liable to derangement.

Improvements in Means for Preventing Fibres from Wrapping the
Drawing-off Rollers of Combing Machines.
We, JOHN LITTLE HALLIDAY, of Cragg Mills, Shipley, in the County of
York, Wool Comber, and LEWIS SHORE, of the same place, 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, that is to say:
Our invention relates to improvements in means for preventing fibres from
wrapping the drawing-off rollers of combing machines, having more especial
reference to the rollers used in connection with those machines known as
"Noble's Combs," and consists of the construction and arrangement of means
whereby the said wrapping of the drawing-off rollers is entirely prevented thus the
damages to the comb and the loss of time accruing from such undesirable occurrences
are entirely avoided.
In the accompanying sheet of drawings
Fig. is a top view of a sufficient portion of a combing machine to shew the
application of our invention.
Fig. 3 is side view of parts shewn by Fig. 1.
Fig. 3 is side elevation, enlarged scale, shewing our improved parts in detail and
Fig. 4 is a perspective view of one of these parts.
We attain the object of our invention by mounting a supplementary roller a
(or a) in such a manner as to be in suitable proximity with the bare or uncovered
drawing-off roller (or 6') and imparting motion to this roller a (or a¹) as by the
wheel (e) which gears with the wheeld (d) and the wheel e (e), in such a manner
as to cause it, said roller a (a¹) to revolve in the same direction (as shewn by the
arrows) and at about the same rate of speed as said drawing-off roller (¹)
is rotated.
The outer or peripheral surface of the roller a (a¹) is preferably formed of
"roller cloth" and by the bearances g (g) upon which it is mounted being made
adjustable, this roller a (a) may be and preferably is adjusted in position for its
outer surface to rub against the outer surface or outer edges of the ridges or flutings
formed on the drawing-off roller b (b) above described.
Now since the two rollers a (a) and (b) revolve in the same direction as shewn
by the arrows (which means that at the point or line of contact with each
other they are travelling in opposite directions), it follows that any fibre that might
tend to wrap or encircle the drawing-off roller, is rubbed, forced or impelled in a
contrary direction from doing so by this roller a (a) which (roller a or a') also aid
its (ie. the fibre forming part of the sliver h or h¹) passage in the proper direction
(indicated by the arrow or ¹) after having thus prevented it from wrapping as
above described, and so the object desired is attained.
The covering of the roller a (a) is preferably performed by attaching one end
of a strip of roller cloth to, at or near one end say a² and winding said cloth
spirally (see Fig. 4) around said roller a finally attaching the other end of said cloth
near the other end a³ of said roller a by which means said covering of cloth is
rendered less liable to derangement. The outer end a³ of the roller a we preferably
make of the shape shewn by Fig. 4 so that when the cloth is wound around said
roller, one or another of the flattened sides of said outer end is sure to be in suitable
position for the attachment of the loose end of cloth.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is performed, we declare that what we
claim is :-
1. The combination of a supplementary roller with the ordinary drewing-off'

page_text: rollers of a combing machine, said supplementary roller being operated relatively
therewith substantially as specified.
g
2. The roller a the wheels c and d and the adjustable bearances 9 in combination
with the drawing-off roller b and the wheel e substantially as herein described and
for the purposes specified.
