PROVISIONAL SPECIFICATION.
Improvements in Preparing and Spinning Machinery for Cotton and
other Fibres.
I JOSEPH TURNER 76 Edward Street, Lower Broughton, Manchester, Mechanic
do hereby declare the nature of this invention to be as follows:-
The construction of the stands or bearings for the drawing rollers of preparing
and spinning machinery in such a way that I can obtain larger sized necks or
bearings of such rollers, and consequently considerably increasing their strength
compared with what has hitherto been usual, and I also get room for stronger
supports or bearings. This I effect by making the stand or bearing in such a way
that the stand or bearing of the one roller is out of line with the bearing of the
roller next to it, and this enables me to get room to make the necks or bearings of
such rollers of sufficient strength, whilst keeping the stands or bearings in which
the rollers work of additional thickness also, and thus of greater strength. This
can either be done by making the rollers of unequal lengths, one bearing being on
the right side of middle support, and the other on the left, or if the bearings or
supports of the front roller for example were in the middle, that of the second
might come on both sides of the front one, or the front roller bearing may be made
wide enough so as to be cut out for the stand or bearing of the second roller to
pass between two parts of it.

Improvements in Preparing and Spinning Machinery for Cotton and
other Fibres.
I JOSEPH TURNER of 76 Edward Street, Lower Broughton, Manchester, in
the County of Lancaster, Mechanic, 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 and accompanying drawings :—
My said invention relates more particularly to the stands and bearings of
drawing rollers in preparing and spinning machinery and consists in improved
constructions and arrangements of such stands and bearings, the principal object
being to permit of the front or other pairs of rollers being set more closely
together and if need be reduced in diameter, so as to deal with shorter staples of
fibre if requisite, while at the same time retaining the usual diameter of the necks
of the rollers or even increasing their diameter, and also to give the necessary
strength or thickness to the stands or bearings in which the rollers work.
All of these advantages are obtained by setting the respective bearings of each.
pair of rollers out of line with each other so that the stands pass each other or are
let into each other the room thus gained by causing the stands to avoid each other,
being utilised as already said to bring the rollers closer together even when their
diameter is reduced; to maintain or increase the diameter of the roller necks; and
to give the necessary strength to the stands. This can be done by making the
roller necks of unequal length, one bearing being on the right of the middle support
and the other on the left side; or if the bearings or supports of the front roller

page_text: for example are in the middle, then the bearings of the second roller might come
on both sides of the front bearings; or the front roller bearings might be made
wide enough to permit of their being cut out so as to allow the stands or bearings
of the second roller to pass into the recess thus formed.
The invention will be best understood from the following description of the
annexed sheet of illustrative drawings.
Fig. 1 of the drawing is a side elevation of an ordinary four draft roller
arrangement.
Fig. 2 is a plan of the four bottom rollers to a slightly reduced scale, illustrating
the arrangement in which the front bearings are lengthened and cut out about the
middle to admit the stands of the second roller.
Fig. 3 is a plan to the same scale as Fig. 1 showing the first and second stands or
bearings placed out of line with each other.
Referring in the first place to Fig. 1 the front bottom roller is lettered a, the
second b, the third c and the fourth d. These rollers are shown in section. The
top rollers are lettered respectively a, b, c, and d². The bearings or stands in
which the rollers revolve are marked e, f, g and h. The supporting bracket to
which the stands are secured by the bolts is lettered k. It is of most importance
that the first and second pairs of rollers a, a¹ and b, ¿¹ should be of limited diameter
and be brought as closely together as possible, and in the drawing it will be seen
that these pairs of rollers almost touch. To effect this without diminishing the
size of the necks / of the rollers or reducing too much the thickness of the stands,
I cause the stands or bearings e, f to pass or avoid each other. For example
looking at Fig. 1, it will be seen that the back of the stand e appears to overlap or
pass the front of the stand f, the front edge of the stand f showing in dotted lines
behind the stand e. This result may be obtained in the manner shown at Fig. 2 by
lengthening the bearings e and cutting a recess & out of the middle part of each,
so as to admit of the second stands f entering these recesses and thus enabling
them to carry their roller b closer up to the roller a, all as very clearly shown in
Fig. 2.
To particularise the position of the bearings and to render their disposition
more easily apparent I have section-lined them in Fig. 2. In Figs. 1 and 2, only
the bearings of the first and second pairs of rollers are modified because in practice
these are the only two pairs in the draft that, generally speaking require to be
brought closely together. But it will be evident that the bearings of the remaining
pairs of rollers might be arranged in the same manner.
As a modification of this arrangement I might locate the bearings in the manner
shown at Fig. 3. Here the bearings e of the front roller a are kept to one side of
the stand bracket, while to avoid and pass this front bearing e, the second bearing f
is placed to the other side of the stand bracket.
Thus practically the same effect is obtained as is described relatively to Fig. 2.
It will be evident that these two dispositions do not exhaust the possible
arrangements of the stands or bearings in accordance with my invention as the
said stands or bearings might for example be arranged in échelon.
But whether let into each other, or arranged in hit-and-miss order or in échelon,
the results obtained are the same viz. maintenance or increase of the size of the
roller necks; power of reducing the diameters of the drawing rollers and of
bringing the respective pairs of rollers more closely together; and the strengthening
of the stands which support the roller necks or journals.
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.
Arranging the stands or bearings of drawing rollers used in preparing and
spinning machinery in such a manner as to provide for the use of rollers of smaller
diameters placed more closely together to suit short stapled cotton, while at the
same time preserving or if need be increasing the usual diameters of the necks of

page_text: such rollers and also the thickness of the stands or bearings such arrangement
being effected by placing the stands or bearings of the respective sets of rollers out
of line with each other, alternately or otherwise, for the purposes and substantially
as described and shown.
