I, WILLIAM BROWN, of Ettrick Lodge, Selkirk in the County of Selkirk, North
Britain, Yarn Spinner, 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 machine or engines in such a manner, that the
fibrous material on passing through the machine is operated upon in an unbroken
sliver, so as to produce worsted like yarn with ordinary wool, without the same
having to go through the operation of combing afterwards; and to remove the fibre
from the doffing cylinder in a number of slivers without dividing the said cylinder
with rings or cut spaces as is now the common practice.
The carding engines constructed according to this invention, are applicable for
carding wool, cotton or silk, and other fibres usually operated upon by carding
machines; and in order to accomplish my object, I mount a succession of "worker
rollers over a portion of the circumference of the "swift" cylinder or cylinders, and
place between each pair of "worker" rollers, a small roller by which the fibre is
prevented from falling on to the swift cylinder, before reaching the point of contact
of the "worker and said cylinder, and by which the fibre is equalized, kept, and
delivered in a regular sheet to the doffer.
If required to divide the fibre before it leaves the machine or engine into a number
of slivers, I place between the "swift" and doffer cylinders, a thin plate divided with
as many openings as the number of slivers or threads required; the partitions
between the openings dividing the fibre which passes through the spaces on to the
doffer cylinder for removal in the same manner as when the latter is divided with
rings or cut spaces.

I, WILLIAM BROWN, of Ettrick Lodge, Selkirk, in the County of Selkirk, North
Britain, Yarn Spinner 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 machine or Engine in such a manner that the fibrous
material in passing through the machine is operated upon in an unbroken sliver,
sheet or web so as to produce when spun, worsted-like yarn, with ordinary wool,
without the same having to go through the operation of combing.
Hitherto in this class of machine, the wool or fibrous material in passing through 1
with the cylinders has been taken up by the workers revolving in a contrary direction
to the cylinders, and by means of the strippers, the wool is cleared from the workers
and returned to the cylinders, which mode of carding gives to the wool a confused
appearance.
I accomplish my object by mounting a succession of workers over a portion of the 1
circumference of the cylinder, and place between each pair of workers, a small
roller by which the fibre is prevented from falling on or returning to the cylinder
until it reaches the point of contact of the following worker and the cylinder by
which means the fibre is always carded in one direction and delivered in a regular
sheet web or sliver to the doffer.
In order to more fully explain my invention, I have appended three sheets of
drawings in which Fig. 1 represents a side view in outline of a portion of a carding
engine sufficient to explain my invention. Fig. 2 is a detail of a portion of the
cylinder with some workers and my additional rollers shewn thereon: Fig. 3 a detail
shewing a mode of operating the workers and additional rollers and Fig. 4 is a plan
of the same.
The ordinary cylinder covered with card cloth is indicated by the letter A and the
workers W are mounted on suitable brackets which may be of the ordinary
construction attached to the framework and my additional rollers R placed between
the workers W may be carried by similar brackets to those carrying the workers.
The workers Ware driven in the ordinary manner by chains or other suitable
gearing. In the drawings I have shewn them driven by chains C and C operated
by the pulley D and conducted somewhat in the manner shewn by dotted lines on
Fig. 1, the chain C passing over wheels E, and chain ("passing over wheels E³,
secured on the respective worker shafts.
The series of wheels E and E¹ have not all the same number of teeth, the number
on each wheel diminishing towards the doffing or delivery side of the cylinder A, so
that each worker rotates faster than the preceeding worker, and each of my additional
rollers has a surface speed equal to that of the preceeding or faster worker, motion

page_text: being given to the additional rollers R by spur wheels F and pinions F¹ mounted on
the respective worker and additional roller shafts, or the latter may be driven by
chains or bands the same as the workers.
The direction of the rotation of cylinder A, workers W, and my additional rollers R,
is indicated by the arrows as shewn on drawings and the fibrous unbroken sliver,
sheet, or web, passing along in one direction only at S in one continuous sheet is
indicated by arrows 1.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
The combination and arrangement of the workers W and the revolving rollers R
substantially in the manner and for the purpose hereinbefore described in reference to
and as indicated by the drawings hereunto annexed.
