· Improvements in Carding Engines.
We, DANIEL BATEMAN BRIGGS, of Ludlam Street, Bradford, in the County of
York, Commission Wool Comber, and WILLIAM EASTWOOD, of 31 Great George
Street, Leeds, aforesaid, Commercial Traveller, do hereby declare the nature of this
invention to be as follows:-
This invention relates to certain improvements in carding engines, and has for its
object the arrangement of the apparatus, so that the wool or other textile fibre is cleared
from burrs or foreign matter, and consists in passing the wool or other textile fibre,
as it leaves one of the carding cylinders of an ordinary carding engine between rollers.
These rollers are mounted in horizontal journals, and the upper roller or rollers are
made with a number of semicircular lugs or protrusions on their peripheries, the lugs
being at regular intervals, and the lower roller or rollers are made with a number of
indentations or hollows, to correspond with the lugs or protrusions of the upper roller
or rollers. The position of the rollers may be reversed, but the effect of the lugs
pressing the fibre into the hollows, whereby any foreign matter in the form of burrs
is reduced to dust and drops out of the fibre, is the same in either case.

We, DANIEL BATEMAN BRIGGS, of Ludlam Street, Bradford, in the County of
York, Commission Wool Comber, and WILLIAM EASTWOOD, of 31 Great George
Street, Leeds, aforesaid, Commercial Traveller, 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 carding engines, and has for its
object the arrangement of the apparatus so that the wool or other textile fibre is
cleared from burrs or other foreign matter, and consists in passing the wool or other
textile fibre as it leaves one of the carding cylinders of an ordinary carding, engine,
between rollers of special construction.
In order to show more clearly our invention, we append a sheet of drawings,
showing in Fig. 1 the side elevation of an ordinary carding engine with our improved
rollers fixed thereto, and in Figs. 2 and 3 enlarged views of our improved rollers,
Fig. 2 being the elevation of a portion of a pair of such rollers, and Fig. 3 being a
cross section in line a-b in Fig. 2.
The wool or other textile fibre after being taken from the middle doffer A by means
of the reciprocating knives B, is passed in a film between the rollers D, D, and E,
which are fixed in suitable bearings, parallel to the carding cylinders. The rollers D, D,
and E are not of the ordinary plain or fluted type usually employed in machines for
the treatment of textile fibres, but are of special construction. The upper rollers D, D,
we construct with a number of semispherical lugs or protrusions F on their peripheries
at equal and regular distances. These upper rollers D, D, we term the male or
driving rollers, and the lower roller E we term the female or driven roller, and wo
construct the latter with a number of indentations or hollows G on its periphery to
correspond with the semispherical lugs or protrusions of the rollers D, D.
sliver of wool or other textile fibre passes between the rollers D, D, and E in a film,
any foreign matter or substance in it is crushed and reduced to dust, and is got rid off
in subsequent treatment on the back carding cylinder H and the back doffer K.
As the
We are well aware that plain and fluted rollers are now used for the purpose of
clearing wool or other textile fibre from any foreign matter that may be therein, by
passing the fibre between the same in a film, but with our improved rollers the crushing
effect is superior and more effectual, and moreover it is not necessary with our improved
rollers for the sliver of the fibre to be so thin as is the case when plain or fluted rollers
are used. Instead of two rollers D, D, one, or more than two might be used, and
sets of rollers can be placed between any or all the cylinders of a carding engine.

page_text: Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
.
The rollers D, D, and E, working between the cylinders of an ordinary carding
engine, the rollers D, D, having a number of lugs or protrusions on their peripheries,
and the roller E having a corresponding number of indentations to receive such lugs
or protrusions, all arranged substantially in the manner as shown and described, and
for the purpose herein set forth.
