Preparing Cotton and other Fibrous Materials.
We JOSEPH DUGDALE, of the firm of John Dugdale and Sons, of Blackburn, in
the County of Lancaster, Machine Makers etc., and GEORGE HAWORTH in the
employ of the said firm Carder, do hereby declare the nature of said Invention for
IMPROVEMENTS IN DRAWING, SLUBBING AND INTERMEDIATE FRAMES FOR PREPARING
COTTON AND OTHER FIBROUS MATERIALS to be as follows:-
The object of our Invention is to facilitate the means for pieceing broken ends or
sliver and our Invention relates to the Invention for which Letters Patent were
granted to Edward Dugdale, Joseph Dugdale and George Haworth on the 16th day
of July 1879 No. 2892.
Instead of the ordinary pair of rollers placed between the stationary guide and the
drawing rollers we now propose to employ a top roller and two bottom rollers, each
of the latter having a groove cut around its circumference between each pair of
slivers and in place of supporting the top rollers as described in the aforesaid Patent,
each top roller which is long enough to cover two slivers is supported by the two
bottom rollers and guided or held in position by a collar or flange round its
circumference which fits into the grooves of the lower rollers.
An alternative arrangement consists in making the collars or flanges on the bottom
rollers and a corresponding groove or recess in each top roller, or the bottom rollers
may be reduced slightly in diameter, say one eighth of an inch for a plain top roller
to lie in, the slivers passing over the bottom rollers where they are reduced in
diameter.
Each of the arrangements mentioned might be adapted to a single bottom roller
used in connection with short top rollers in which case the centre of the top rollers
would be set to one side of the lower roller preferably toward the stationary guide
and the top rollers would be supported preferably by a plate secured to the ordinary
back plate of the frame against which they lie.
When the sliver breaks it can be pieced up without lifting the short top roller.

Preparing Cotton and other Fibrous Materials.
We JOSEPH DUGDALE of the firm of John Dugdale and Sons of Blackburn in the
County of Lancaster Machine Makers etc. and GEORGE HAWORTH in the employ of
the said firm Carder do hereby declare the nature of said Invention for IMPROVEMENTS
IN DRAWING SLUBBING AND INTERMEDIATE FRAMES FOR PREPARING COTTON AND
OTHER FIBROUS MATERIALS 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 our Invention is to facilitate the means for piecing broken ends or
slivers and our Invention relates to the Invention for which Letters Patent were
granted to Edward Dugdale Joseph Dugdale and George Haworth on the 16th day of
July 1879 No. 2892.
And in order that our Invention may be fully understood and readily carried into
effect we will describe the accompanying sheet of Drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a plan Figure 2 a front view and Figure 3 an end sectional elevation of
part of a drawing frame to which our Invention is applied. Figures 4 and 5 are
front elevations illustrating alternative arrangements of drawing rollers and Figure 6
is an end sectional elevation of an arrangement with a single bottom roller according
to our Invention.
In the arrangement illustrated by Figures 1, 2 and 3 instead of the ordinary
arrangement of parts between the stationary sliver guide or bar a and the drawing
rollers not shown in the Drawings we employ a top roller band two bottom rollers c
and d each of the latter having a groove c and d respectively cut around its circum-
ference between each pair of sliver guide holes a¹ and in place of supporting the top
rollers b as described in the Specification to the aforesaid Patent each top roller b is
now supported by the two bottom rollers c and d and guided or held in its true
position by a collar or annular flange b¹ which fits into the grooves c and d of the
bottom rollers. Each top roller b is made long enough to cover two slivers and it
will be readily seen that when a sliver breaks it can be pieced without lifting the top
roller.
In order to prevent the slivers getting into the grooves in the bottom rollers we
propose to employ a number of guides formed or fixed on a plate e secured to the
framing one of these guides e¹ being placed opposite each groove c¹ in the front
bottom roller c. The top rollers b we prefer to make plain but the bottom rollers c
and d may be either grooved as shown or fluted or plain and either or both of the
bottom rollers c and d are driven positively by gearing or otherwise.
An alternative arrangement consists as shown in Figure 4 in making or fixing
collars or annular flanges on the bottom rollers and d respectively and a
corresponding annular groove 62 in the top roller b. or as shown in Figure 5 the

page_text: bottom rollers may be reduced slightly in diameter say one eighth of an inch for a
plain top roller b to lie in the slivers in this case passing over the bottom rollers where
they are reduced in diameter.
Each of the foregoing arrangements shown and described may be adapted to a
single bottom roller c used in connection with short top rollers 6 as illustrated by
Figure 6.
In this instance the centre of the top rollers b is set rather to one side of a
perpendicular taken through the centre of the bottom roller c and the top rollers b
are supported by a plate f secured to the ordinary back plate of the frame not shown.
To diminish friction we prefer to employ a number of small rollers g mounted on the
plate the top rollers 6 are arranged so that each collar 61 (Figures 1, 2 and 3) or
each groove b² (Figure 4) or the surface of the roller b (Figure 5) works in contact
with one of the antifriction rollers g.
We have only shown and described our improvements as applied to a drawing frame
it is obvious that they are equally applicable to slubbing and intermediate frames.
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-
1. The combination with a pair of bottom rollers provided with annular grooves
of top rollers provided with collars or annular projections to fit said grooves
substantially as herein described with reference to Figures 1, 2 and 3.
2. The combination with a pair of bottom rollers provided with collars or annular
projections of top rollers provided with annular grooves to receive said collars or
annular projections substantially as herein described with reference to Figure 4.
3. The combination with a pair of bottom rollers recessed or reduced slightly in
diameter of top rollers arranged to fit in said recesses substantially as herein described
with reference to Figure 5.
4. The combination with a single bottom roller provided with a series of annular
projections or grooves or recesses of a top roller constructed and arranged substantially
as herein described with reference to Figure 6.
5. The several constructions combinations and arrangements of parts constituting
our improvements in drawing slubbing or intermediate frames substantially as herein
shown and described.
