Improvements in the Method of and Apparatus for Feeding
Carding Engines.
We, THOMAS HENRY ACKROYD of Birkenshaw Mills, Birkenshaw near Leeds
in the County of York, Spinner and Manufacturer, ALLAN BROADLEY of the
same place, Manager and SAMUEL RAISTRICK, also of the same place Carding
Overlooker do hereby declare the nature of this invention to be as follows :-
This invention relates to certain improvements in the method of and apparatus
for feeding carding Engines and has for its object the feeding of the wool more
evenly to a carding Engine whereby the Carding Engine is enabled to card the
wool better than hitherto.
We accomplish our object by substituting for the endless fluted leather sheet or
band passing round the feed rollers in front of a carding Engine, an endless
sheet or band of card clothing by which means we are enabled to feed the wool
more ovenly to the card than hitherto and as a consequence of this even feeding of
the carding Engine we find that the wool is as well carded when entering, the first
swift on the carding engine itself as it was under the old method of feeding when
entering on the last swift.

Improvements in the Method of and Apparatus for Feeding
Carding Engines.
We, THOMAS HENRY ACKROYD, of Birkenshaw Mills, Birkenshaw, near Leeds,
in the County of York, Spinner and Manufacturer, ALLAN BROADLEY, of the same
place, Manager, and SAMUEL RAISTRICK, also of the same place, Carding 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 certain improvements in the method of and apparatus for
feeding carding engines, and has for its object the feeding of the wool or other fibre
more evenly to the cylinders and thereby to enable the machine to card the wool or
other fibre better than when fed in the manner as hitherto and consists in substituting
for the endless leather sheet or band in front of the carding engine, two endless sheets
or bands of card clothing, for conveying the fibre from the ordinary endless and
traversing lagged apron to the "licker in ; "by which means the fibre is fed or
distributed more evenly to the card cylinder than by the ordinary method.
In the accompanying drawings Fig. 1. represents a side view of such portions of a
carding engine as are required to explain our invention which is added thereto, the
gearing for driving the additional rollers being removed from the drawing in order to
more clearly show the invention.
Fig. 2. is a plan of the same and gearing for driving the rollers.
Fig. 3. a front view of a portion of the rollers, and
Fig. 4. a sectional detail of the additional rollers, clearer roller and a portion of
the licker in."
The fibre to be carded is distributed on the ordinary lagged apron A. in the usual
manner, by which it is delivered to the endless sheets of card clothing B. and C. each
sheet being placed on a pair of additional rollers supported by brackets mounted on a
saddle D. secured to the frame at each side of the machine.

page_text: Each bracket is made to slide on the saddle D. and is respectively adjusted by the
screws E. E. for keeping the endless sheets of card clothing B. and C. at the proper
degree of tension. The bottom rollers for sheet B. are mounted in fixed journals-one
of which is formed in each saddle and the other in the bottom portion of the
brackets F.; the rollers for the upper sheet C. being supported by adjustable journals
placed in the slots of the brackets, each journal having a vertical screw S. attached
thereto which passes through the bracket cap G. where it engages with a wheel nut H.
on the turning of which the journal may be adjusted and the ends of the rollers
regulated to suit the requirements of the feed.
The endless cards may be operated by gearing J. in connection with the shaft of
the "licker in" roller or cylinder K. or by gearing in connection with any convenient
part of the machine, the endless sheets of card B. and C. being geared together and
moving in the direction of the arrows, so that on the fibre being placed on the
traversing lagged apron A. it is constantly fed to the said sheets which convey it to
the "licker in," and is prevented leaving the said sheets otherwise than in a
comparatively straight condition by the clearer roller R.
By the card sheets B. and C. having more surface for retaining the fibre than is
the case with the ordinary feeding rollers where the "nip" is necessarily narrow, the
fibre is more securely held therein by the teeth of the cards B. and C. so that it is not
so readily delivered, it having to be drawn through the teeth of the said cards before
passing on to the "licker in ;" thus by these means, the fibre is considerably
straightened by being drawn through the teeth of the card sheets B. and C. and is
therefore less liable to ride on the tops of the card teeth of the respective cylinders and
rollers of the machine, than when fed in the ordinary unstraightened manner: thus
by being delivered in a straighter condition, the fibre is more thoroughly imbedded in
the teeth of the cards of the respective rollers and cylinders, and thereby more
completely "lashed out or straightened in its passage through the machine, than is
"
the case when fed in the usual manner.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, we declare that what
we claim is-
The combination with a carding engine of endless cards for conducting the fibre
from the traversing apron to the "licker in arranged substantially as shown and
described.
