Improvements in Carding Engines for Cotton and other Fibrous
Substances.
I, JOHN WALMSLEY, of Victoria Road, Huddersfield in the County of York, Mill
Manager, do hereby declare the nature of this invention to be as follows:-
My invention consists principally in the employment of a flexible belt studded with
card teeth, in place of the revolving card cylinder hitherto in use, and also in improved
means of applying card flats to operate with such flexible belts in the process of
carding.
To carry out my invention I employ two cylinders of the width of ordinary card
cylinders and with plain surfaces. These cylinders are mounted upon shafts running
in bearings carried by a suitable frame, the centre of one cylinder being in a vertical
line over the centre of the other.
The larger or main cylinder is the lower of the two, and upon the shaft of this
cylinder is fixed the pulley by means of which the machine is driven. Stretched upon
these two cylinders is the flexible belt set with card teeth, which belt takes the place
and performs the duties of an ordinary card cylinder.
Parallel with the axes of the top and main cylinders, and at either side of them,
are mounted rollers for the purpose of carrying the card flats, which flats travel in
contact with the teeth of the flexible belt herein before referred to; from the periphery
of the main cylinder, rising along the vertical plane where the belt runs between the
two cylinders, over the top cylinder and downwards along the other vertical plane
where the flexible belt. passes from the top to the main cylinder, the card teeth
being still in contact until the flats reach the opposite side of the main cylinder
to that from whence they started, where they pass outward and over the four
rollers hereinbefore referred to, which carry the card flats clear of the carding
belt until they come in contact with it again at the periphery of the main
cylinder.
The carding belt is prevented from curving inwards, in the space between the upper
and lower cylinders, by means of flat metal guides or slips held to its inner surface
and made adjustable by set screws or wedges.
The ordinary "taker-in," doffer, comb, draw box, and coiling motion are employed
in conjunction with my improvements, and are operated in the ordinary manner.
The advantages claimed for my improvements are that the effective carding surface
formed by the vertical planes where the carding belt passes from one cylinder to
another, in addition to that formed by the curved surface where the belt passes over
the upper cylinder, is much greater than that obtainable upon an ordinary carding
cylinder, where only a small are of the circle is operating at once; I am therefore
enabled to card the material much more thoroughly in a given time, and therefore
at a less cost than by the older process, and the improved machine occupies less space
than one of the form hitherto in use.

Improvements in Carding Engines for Cotton and other Fibrous
Substances.
I, JOHN WALMSLEY of Victoria Road, Huddersfield in the County of York, Mill
Manager, 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 :-
My invention consists principally in the employment of a flexible belt covered with
ordinary card clothing in place of the revolving card cylinder hitherto employed, and
also in improved means of employing card flats to operate with such flexible belt in
the process of carding.
To carry out my invention I employ two cylinders of the width of ordinary card
cylinders and with plain surfaces.
These cylinders are mounted upon shafts running in bearings carried by a suitable
frame, the centres of the two cylinders being in the same vertical line.
The larger or main cylinder is the lower of the two and upon one end of the shaft
of this cylinder is fixed the pulley by means of which the machine is driven.
Stretched upon and revolving with these two cylinders is a flexible belt set with card
teeth as above described, which belt takes the place of and performs the operations of
the ordinary card cylinder.
Parallel with the axes of both the top and bottom cylinders and at either side
of them are mounted conducting rollers for the purpose of carrying the card flats,
which flats travel in contact with the teeth of the flexible belt, herein before referred
to, from the periphery of the main cylinder rising along the vertical plane where
the belt passes from the top to the bottom cylinder, then over the upper half of the
top cylinder, and downwards along the other vertical plane, where the flexible belt
descends and passes from the top to the bottom cylinder; the two sets of card teeth
being still in contact until the flats reach the opposite side of the main cylinder to
that from whence they started, where they pass outward under one of the conducting
rollers hereinbefore referred to, which rollers support the card flats clear of the
carding belt until they come in contact with it again at the periphery of the main
cylinder, except when passing over the top of the upper cylinder where the card flats
are carried upon the ordinary flexible bends.
The carding belt is prevented from curving inwards in the space between the upper
and main cylinders by means of flat guides held to its inner surface and adjusted by
set screws or wedges, or by preference, rollers are employed for this purpose which
are mounted across the machine, and which are adjusted to touch with their peripheries
the inner side of the carding belt.
The ordinary "licker-in," doffer, comb, draw-hox and coiling motion are employed
in combination with my improvements, and are operated in the ordinary manner.
In order to enable my invention to be fully understood I will proceed to
describe the same with reference to the accompanying drawing which represents
a sectional elevation of a sufficient portion of a carding engine to illustrate my
improvements.
The side frame of the machine is represented at C, the lower or main cylinder at A
and the upper cylinder at B. The carding belt which passes over the top and under
the bottom cylinder is represented at G, and the revolving card flats at F passing
round the conducting rollers HH and carried by flexible bends over the top
cylinder B. The direction in which the surfaces of the cylinders, the carding belt,
and the carding flats travel is indicated by arrows. Effective carding contact begins
at the point K and is continued over the top of the cylinder B to the point L where
it ceases, and the carded fibre is stripped off the cards by the doffer D. The "licker-
in" is represented at E. The two rollers J prevent the carding belt from curving or
bellying inwards.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what I
claim is,
1. In a carding engine for cotton or other fibrous materials the employment of a
flexible carding belt running upon upper and lower cylinders in combination with
revolving card flats, mounted and operated substantially in the manner described and
as represented in the accompanying drawing.
2. In a carding engine the combination of a carding belt stretched upon upper and
lower cylinders and prevented from curving inward between the two cylinders by
means of guides or rollers, with revolving card flats carried upon conducting rollers
and flexible bends substantially in the manner and for the purpose described, and as
represented in the accompanying drawing.
3. In a carding engine the combination of an ordinary "licker in" and doffer with
the carding belt and revolving card flats mounted and operating substantially in the
manner described and as represented in the accompanying drawing.
4. In a carding engine the general arrangement and combined operation of the
various parts substantially as described and represented.
