PROVISIONAL SPECIFICATION.
Improvements in Machinery or Apparatus for Carding Wool and
other Fibres.
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 machinery or apparatus for carding
wool and other fibres and its object is to dispose burrs and the like more on the
surface of the "licker-in " or in a more favourable position for the beaters to
remove and also to more perfectly disentangle the fibres at the initial stage before
they are acted upon by the finer pins or teeth which latter are apt to break any
fibres not in a fairly loose condition.
For this purpose we employ one or more auxiliary rollers of somewhat similar
construction to the feed rollers and having its or their teeth or pins set in the same
direction as the top feed roller and they are rotated in the same way.
Preferably more than one auxiliary roller is employed and they are mounted
immediately above the top feed roller and arranged so that their pius intersect each
other. The auxiliary rollers are preferably not driven at exactly the same speed
nor at the same speed as the feed rollers but at a speed most suitable to the parti-
cular class of fibres being operated upon, and they may be actuated by a pitch
chain or in any other convenient manner. The clearing roller usually fitted above
the top feed roller is placed above the top auxiliary roller.

COMPLETE SPECIFICATION.
Improvements in Machinery or Apparatus for Carding Wool and
other Fibres.
We, WILLIAM HORSFALL GREENWOOD, Commission Wool Comber, and
FREDERICK FARRAR, Manager, both of Spring Mill Street, (late 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 machinery or apparatus for carding
wool and other fibres and its object is to dispose burrs and the like more on the
surface of the "licker-in" or in a more favourable position for the beaters to remove
and also to more perfectly disentangle the fibres at the initial stage before they are
acted upon by the finer pins or teeth which latter are apt to break any fibres not in
a fairly loose condition.
For this purpose we employ one or more auxiliary rollers of somewhat similar
construction to the feed rollers and having its or their teeth or pins set in the same
direction as the top feed roller and they are rotated in the same way.
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 both of the figures.

Figure 1, is a cross section of the feed rollers and clearing roller of a carding
machine with one of said auxiliary rollers in position between the clearing roller

page_text: and the top feed roller. The broken lines A and B respectively represent a portion
of the periphery of the licker in and the top of the side frame.
Figure 2, is a side view illustrating a convenient manner of driving the clearing
roller.
The feed rollers C and D are arranged and driven in the ordinary manner and
the auxiliary roller E placed in the same position as the ordinary clearing roller
with its pins F intersecting those of the top feed roller may be driven in a similar
manner to the said clearing roller but at a somewhat different speed. Instead how-
ever of having the pins set at the same angle to a radial line or inclined in the same
direction as the clearing roller they are inclined in the reverse direction so as to
correspond to the top feed roller D. The roller E has therefore a similar teasing
action on the fibres carried by the licker in as the top feed roller and this action is
increased by driving E at a somewhat slower speed. Besides this teasing action
the roller E has a decided tendency to bring burrs and the like to the surface of
the licker in in position to be removed by the beaters.
More than one auxiliary roller may be employed mounted one above the other
with their pins intersecting that is to say with the pins of one roller working in
between the pins of the neighbouring rollers. These auxiliary rollers are preferably
not driven at the same speed but at a speed most suitable to the particular class of
fibres being operated upon. Generally speaking we find it advisable to drive each
successive auxiliary roller at a somewhat slower speed.
The clearing roller G is arranged to clear the roller E in a similar manner to
which it is usually employed to clear the roller D.
We find it convenient to mount the roller G in bearings formed in an arm H at
each end adjustably secured to the standards J on which the bearings for the beaters
are usually mounted. The arms H are also supported by a light standard Kat
each side. The roller G may be driven by the endless chain L connecting the
chain wheels M, M rigidly mounted on the shafts N, N of the rollers G and D.
An ordinary tension pulley P mounted on the bracket R is provided to enable the
tension of the chain to be regulated.
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 carding machine an auxiliary roller or rollers driven in the same direction as
the top feed roller and having its or their pins inclined in the reverse direction to
the ordinary cleaning roller, substantially as herein shown and described and for the
purpose specified.
