page_text: I JAMES CLARKE of Acre, Haslingden, Lancaster, Manager do hereby declare the
nature of my said invention to be as follows:-
The object of this invention is so to improve a carding engine that during the
carding process the production of lumps or flocks in the fibrous material under
treatment shall be entirely avoided and the production of "fly" considerably lessened
and consists in the application to each side of the carding engine and between the
main carding cylinder and the doffer of a metal plate from which projects a suitable
segment or projection capable of filling up the gap or angle which has hitherto existed
at these points and so has permitted the entrance of a current of air having the effect
of blowing the material into lumps or flocks and which have passed forwards with the
sliver.
These segment plates are affixed to the framework at each side of the carding
engine and in the space or angle between the top of the main cylinder and the
doffer and also at the bottom thereof so as to close in and effectually prevent the
currents of air setting up as aforesaid.

page_text: I, JAMES CLARKE of Acre, Haslingden Lancaster, Manager do hereby declare the
nature of my said 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 this invention is so to improve a carding engine that during the
carding process the production of lumps or flocks in the fibrous material under treat-
ment shall be entirely avoided and the production of "fly" considerably lessened and
consists in the application to each side of the carding engine and between the main
carding cylinder and the doffer of a metal plate from which projects a suitable segment
or projection capable of filling up the gap or angle which has hitherto existed at
these points and so has permitted the entrance of a current of air having the effect
of blowing the material into "fly" or into lumps or flocks which have passed forwards
with the sliver.
These segment plates are affixed to the framework at each side of the carding
engine and in the space or angle between the main cylinder and the doffer so as to
close in and effectually prevent the currents of air setting up as aforesaid.
On the accompanying drawing I illustrate in Fig. I an inner side view and in
Fig. 2. an edge or front view of one of my improved segmental plates from the
inner side of which projects a segment or projection a carried to a point and
terminating at its lower extremity in a thin steel blade 6 which is curved to the
exact form of the periphery or circumference of the main carding cylinder.
In Fig. 3 I illustrate the application of my improved segment plates to be the
main cylinder c and doffer d of a carding engine. I affix one of my improved
segment plates to the framework at each side of the carding engine (say by a set
screw passing through the frame side and screwing into the fixed nute seen in Figs. 1
and 2), so as to occupy the space or angle between the main cylinder and the doffer
as illustrated.
The segment or projection a on the face of each plate thus extends into the angle
between the cylinder and doffer whilst the lower extremity or thin steel blade 6 passes
in between the cards and round the main cylinder.
In this manner I close in and effectually prevent the currents of air setting up and
also avoid the formation of lumps or flocks and lessen the quantity of "fly" produced
as aforesaid.

page_text: Having thus particularly described and ascertained the nature of this my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
In a carding engine the employment of segment plates mounted and operating
substantially as and for the purposes hereinbefore described.
