We, JOE DICKINSON and HERBERT DICKINSON trading as Dickinson Brothers
and Company of Range Lane Mills, Halifax, Yorkshire, Cotton Spinners and
Doublers" do hereby declare the nature of our invention for "IMPROVEMENTS IN
THE MANUFACTURE OF FANCY COTTON YARNS, AND IN APPARATUS EMPLOYED
THEREIN to be as follows:-
"
Our invention consists in the manufacture of a new and peculiar class of fancy
cotton yarn which may be used either as warp or weft in producing fancy cloth.
In order to produce the said yarn according to our invention we first of all spin
a thick yarn, but not of uniform thickness, such yarn being made undulating or
having thin and thick places alternately along its length.
This yarn is produced by means of the drawing rollers which are made to have
an intermittent motion given to them by space wheels or other means.
The thick soft yarn having thin and thick places in it is then taken to an
ordinary doubling or twisting frame and there doubled in combination with a
finer or harder spun yarn, the natural tendency is that there will be more turns
to the inch upon the thin places of the thick soft yarn than in the thick places
which consequently produces a fancy and ornamental corkscrew effect on the said.
yarn.
The undulating soft yarn can be made either in the mule or preparing frame.

We, JOE DICKINSON and HERBERT DICKINSON, trading as Mess™ Dickinson
Brothers and Company of Range Lane Mills, Halifax, Yorkshire Cotton Spinners
and Doublers do hereby declare the nature of invention for "IMPROVEMENTS IN
THE MANUFACTURE OF FANCY COTTON YARNS, AND IN APPARATUS EMPLOYED
THEREIN "and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :----
Our invention consists in the manufacture of a new and peculiar class of fancy
cotton yarn which may be used either as warp or weft in producing fancy cloth.
In order to produce the said yarn according to our invention we first of all spin
a thick yarn, but not of uniform thickness, such yarn being made undulating or
having thin and thick places alternately along its length.
This yarn is produced by means of the drawing rollers which are made to have
an intermittant motion given to them by space wheels or other means.
The thick soft yarn having thin and thick places in it, is then taken to an
ordinary doubling or twisting frame, and there doubled in combination with a
finer or harder spun yarn, the result of which is that there will be more turns to
the inch upon the thin places of the thick soft yarn, than in the thick places, which
consequently produces a fancy and ornamental corkscrew effect on the said yarn.
The undulating soft yarn can be made either in the mule or preparing frame.
Such being the nature and object of our invention we will now proceed to
describe the same more fully, and for that purpose have annexed the accompanying
sheet of drawings wherein Fig. 1 is enlarged view of a piece of yarn made with
thin and thick places in it for the purposes of our invention. The means we
employ for producing this irregular yarn is illustrated in Fig. 2, which is section of
the drawing rollers A of a mule or other preparing machine, to which drawing
rollers we propose to give an intermittant motion, and this we accomplish by
space wheel B, driven by gear wheels C and D. This space wheel B is in gear
with another space wheel E, fixed on the end of one of the bottom drawing rollers,
whereby intermittant motion is imparted thereto, and by spur wheel a little
intermittion to the remaining drawing rollers, so that as the yarn passes between
such rollers, it is unequally drawn as illustrated in Fig. 1.
.After the unequally drawn yarn as seen in Fig. 1, is produced, it is taken to
an ordinary doubling machine, and doubled or twisted in combination with a fine
hard spun thread. By twisting the two threads together, one of which is hard
and the other soft, and of irregular thickness, it follows that there will be more
twines of the fine hard spun yarn in the thin places of the irregular yarn, than in
the thick places, consequently a corkscrew effect is produced same as seen in Fig. 3.
By employing yarn of different colours, many varied and beautiful effects can be
produced.

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 :-
Firstly-The manufacture of yarn substantially as shewn and described,
whereby corkscrew effect is produced.
Secondly-The mechanism or its equivalent substantially as herein shewn and
described for giving intermittant motion to the drawing rollers of mules or
preparing machines, for producing yarns of different thicknesses.
