Improvements in Connection with Carding Engines for Ensuring
the Division or Separation of Slivers. or Threads of Cotton,
Wool, Silk, or other Fibrous Material.
I GEORGE EASTWOOD of Number 73 South Street Rochdale in County of
Lancaster Card Nailer do hereby declare the nature of this invention to be as
follows:-
:-
My invention relates to Carding Engines for carding fibrous materials, and consists
in applying between the stripper, which I provide with ring spaces and the doffer,
a shaft suitably mounted in the framing of the machine and carrying a number
of circular pieces or drums, such number corresponding with the number of
spaces on the doffer and on the stripper, the spaces formed on the stripper being
opposite to the spaces on the doffer, the circular pieces being concentric with
the shaft, I cover the surfaces of the circular pieces with fillets of card the
surfaces of the circular pieces when covered being conveniently close to the
surfaces of the doffer and stripper respectively, and enter into the ring spaces of
each.
In proximity to the dividing roller which is well known, I employ a shaft provided
with circular pieces and covered with fillets of card, suitably mounted at its
extremities, being similar to the shaft and circular pieces hereinbefore described,
the office of which is to prevent the uniting of the threads at this part and to
ensure the separation of the threads before entering the rubber leathers of the
engine.
.
apply also close to and at any convenient part of the doffer preferably at the
underside thereof, a roller, having strips or pieces of metal projecting beyond its
surface and being in its longitudinal direction.
The operation of my invention is as follows-When the engine is in operation a
suitable rotary motion is imparted to the roller at the underside of the doffer, by this

page_text: means the loose fibres of the material being worked in the engine when passing
from the cylinder to the doffer are stretched out or straightened, and the material is
thus caused to pass between the doffer and the roller in an even or regular form. The
shaft situate between the stripper and doffer having a rotary motion, ensures by
means of the action of the circular pieces an effectual division of the threads or
slivers at such part, from thence the threads pass to the dividing roller, and the shaft
carrying circular pieces being adjusted in close relation thereto, and having a rotary
motion the action and sitnation of such pieces obviate the possibility of the uniting of
the threads on the dividing roller.

I GEORGE EASTWOOD of No. 73 South Street Rochdale in the County of
Lancaster Card Nailer, 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 relates to carding engines for carding fibrous materials and has for
its object to divide into slivers or threads the material being operated upon in the
machine before entering between the rubber leathers of the same, the division of such
material being effected on the doffer.
In order that my invention may be more clearly understood I have hereunto
annexed a sheet of drawings in which like letters of reference indicate like parts
throughout the figures therein shewn.
Figure 1 represents an end view shewing my invention applied to the doffer of a
carding engine.
Figure 2 is a front view of Fig. 1 shewing so much of the doffer of a carding
engine as is necessary to illustrate my invention.
Figure 3 represents an end view of my invention being a similar figure to
Fig. 1 but drawn to a larger scale in order that my invention may be more
intelligible.
Figure 4 is a front view of Fig. 3.
Figures 5 & 6 are end and front views respectively of a compressing roller.
Figures 7 & 8 are front and end elevations respectively of a circular dividing
plate.
Figures 5 and 6 are end and front views respectively of a compressing roller.
Figures 7 and 8 are front and end elevations respectively of a circular dividing
plate.
My invention consists of applying between the stripper a (which stripper I provide
with card fillets and spaces a¹) and the doffer, b. a shaft or roller, c. which roller is
suitably mounted at its extremities in the framing of the machine. On the surface of
the said roller is provided (concentric with its axis and at equal distances from one
another), any convenient number of of pieces of leather or other suitable material
or strips of leather d having metal teeth d¹ being known as card fillets or I may
employ circular plates having serrated cutting edges or saw teeth d³, in the
drawings herewith card fillets are illustrated applied on the roller, c. a suitable number
of fillets being employed thereon to correspond with the number of spaces, e and a'.
There may be provided upon the surfaces of the doffer, b. and the stripper, a,
respectively, for example: A Carding Engine having a doffer 60 inches wide on the
wire may be spaced according to my arrangement so as to admit of 90 threads or
thereabouts being obtained therefrom, consequently I provide a sufficient number of
card fillets or circular serrated plates d³ on the roller, c, to correspond with the
number of spaces e and a¹ required on the doffer, b, and the stripper, a, respectively

"
to produce such number of threads. The roller, c, is placed in a convenient position
with relation to the doffer, b, and the stripper, a, so that the card teeth or the teeth d³
of the circular plates & may and shall enter into spaces e and a¹ formed on the
stripper, a, and the doffer b respectively.
In any convenient position between the dividing roller j¹ and the roller, c, I employ
a bar or plate c¹ in the longitudinal direction of the roller, c. At any convenient
part of the doffer b at the underside thereof I also employ a roller g provided with
any convenient number of wing pieces or projecting metal strips, h, situated about
its surface and in the direction of its length the said roller being situated with
relation to the underside of the doffer so that the wing pieces or strips, h, may at
their outer edges be in contact with the material on the doffer b represented in the
drawings herewith and marked with the letter, i.
The operation of my invention is as follows:-
When the machine is in operation a rotary motion is imparted to the roller, c, by
the aid of a driving band or other suitable means the motion being transmitted
thereto, from any convenient motion shaft of the machine the said roller is caused to
revolve in the direction as indicated by the arrows Figures 1 and 3 by the action of
the card teeth d¹ the material is effectually divided into threads when leaving the
doffer which threads then pass over the rest bar or plate c¹, to and through the
grooves of an ordinary dividing roller j' but according to my arrangement and as is
illustrated in the drawings herewith the ribs or dividing parts of the said roller I..
cause to be situated nearer to the stripper of the carding engine than heretofore,
I which I cause to enter into the spaces of the stripper, a, the material is then allowed
to pass to and between the rubber leathers of the machine which is well known. By
the action of the roller at the underside of the doffer any loose portions or parts of
the material at this part are arrested and collected to the fleece of the material and...
thus the fleece is caused by the aid of the said roller to adhere or lie close to the
doffer and is then allowed to pass to the dividing apparatus before described in an
even and compact form.
Having now particularly described and ascertained the nature of my said i
invention and in what manner the same is to be performed I declare that what'
.1 claim is.
1. The combination of the roller, c, having any suitable number of card fillets d
the stripper, a, being provided with spaces a around its surface and the dividing
roller having its projecting parts situated in the spaces a¹ of the stripper, a, and
the roller, g, substantially as and for the purposes herein fully set forth and described
in the drawings hereunto.
2. The roller, c, having any suitable number of card fillets provided around its
surface situated at the part as indicated in the drawings herewith substantially
as and for the purposes herein fully set forth and described in the drawings.
hereunto.
3. The combination of the dividing roller j¹, with the stripper, a, provided with
spaces a¹ around its surface being situated with relation to each other substantially
as and for the purposes herein fully set forth and described in the drawings
hereunto.
4. The roller, g, provided about its surface with strips of metal, h, to be situated at
any convenient part of the doffer, b, substantially as and for the purposes herein fully
set forth and described in the drawings hereunto.
