PROVISIONAL SPECIFICATION.
Improvements in or relating to Drawing Frames used in the
Preparation of Cotton and other Fibrous Substances, also
applicable to Slubbing and Intermediate Frames.
I, GEORGE TURNER of Broadbottom, in the County of Chester, Mill Manager,
do hereby declare the nature of my said invention to be as follows:-
This invention consists of an improved feed roller arrangement for drawing
frames whereby the slivers may be readily introduced between said rollers and led
between the drawing rollers, or pieced or joined to a sliver end projecting from said
drawing rollers, without having to lift or handle the top feed roller as heretofore.
In accordance with my invention I employ two feed rollers formed in one
continuous length, or in sections and joined together by suitable means, and designed
to extend across the whole width of the drawing frame.
The bottom roller is driven at the usual speed from a spur driving wheel on the
back line of drawing rollers, whilst the upper feed roller is driven positively from
the bottom feed roller by means of spur pinious at the opposite end.
These rollers at each point where a sliver or series of slivers is intended to pass
between them are fluted whilst between such fluted portions the rollers are formed
with curved recesses producing oval or elliptical openings between the said rollers.
Through these openings or apertures aforesaid in the rollers are passed the sliver
end or ends which it is desired to introduce between the drawing rollers or piece or
join with a sliver end projecting from said drawing rollers and the operation of
introducing joining or piecing being effected and the machine started, the pull of
the drawing rollers causes the sliver or slivers to work up the curved recess and
between the fluted portions of the rollers as desired without the need of raising or
lifting the upper feed roller.
It will be obvious that I can bring a sliver to its place from either side of the
fluted portions of the roller, say where two or more slivers are under the control of
any one fluted portion of the feed rollers.
By these improvements I obtain a more positive feed roller action on the slivers
for regulating and avoiding uneven draft.
The improvements are equally applicable to slubbing and intermediate frames.
Dated this 20th day of January 1893.

COMPLETE SPECIFICATION.
Improvements in or relating to Drawing Frames used in the
Preparation of Cotton and other Fibrous Substances, also
applicable to Slubbing and Intermediate Frames.
I, GEORGE TURNER of Broadhottom, in the County of Chester, Mill Manager,
do hereby declare the nature of my said 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 consists of improvements in the feed rollers of drawing frames
whereby the slivers may be readily introduced between said rollers and pieced or

page_text: joined to a sliver end projecting from the drawing rollers without having to lift or
handle the top feed rollers as heretofore.
And in order that my invention shall be the more readily understood and carried
into practical effect I have hereunto annexed a sheet of drawings in which
Fig. 1 illustrates a front elevation of my improved feed rollers and Fig. 2 a
modification thereof.
In accordance with my invention I employ two feed rollers A and B, both of
which (whether formed in one or made in sections) extend from side to side of the
machine. The bottom feed roller B is by preference, driven by the toothed
wheel C from the back line of drawing rollers (not shewn) or other equivalent
source of motion whilst the top roller A is driven from the lower roller B by the
toothed wheels or pinions D at the opposite end.
At the parts where the slivers pass to the drawing rollers the feed rollers are, by
preference fluted or roughened as illustrated to give an increased feeding effect on
the slivers. At points between these fluted portions the rollers are formed with
recesses or reduced portions E, E producing (according to the shape of the recesses)
oval, elliptical, round or other openings E, E¹ where the rollers are in contact as
illustrated.
Through these openings the slivers are passed when threading or introducing
them into the machine or piecing broken ends (which in practice can be effected in
a much quicker and more expeditions way than is possible with the methods at
present adopted) and owing to the pull of the drawing rollers and the shape of the
recesses aforesaid the slivers are caused to travel up the sides of the recessed
portions of the bottom roller until they come between the fluted portions of the
rollers when they are fed in the usual way.
The shape of the recesses may vary, but it is preferred to adopt the shape of
the recess shewn in Fig. 2 as the sliver can more easily climb the side of the recess.
If desired the bottom roller only may be recessed. The fluted portions may vary
in length according as it is required to feed two or more slivers.
It will be obvious that a sliver may be brought to its place from either side of
the fluted portions of the roller say where two or more slivers are under the control
of any one fluted portion of the feed rollers.
By these improvements I avoid what is known as "single" aud I obtain a more
positive feed roller action on the slivers for regulating and avoiding uneven draft.
To enable the top roller to rise in its bearings when any unusual thickness of
sliver passes between the rollers and in order to give the rollers a more sensitive
nipping action I may provide the bearing or pedestal F with a vertical slot Gin
which fits a rod H with one end bearing on the bush or axles of the roller and the
other end passing through a hole in the cap of the bracket. Between the cap and
the roller axis and surrounding the rod is a spiral or volute spring I which is
sufficiently strong to keep the top roller against the bottom roller, but sufficiently.
yielding as to allow the roller axis to rise in its bearing when the unevenness afore-
eaid occurs in the slivers. The same action may be effected by weights.
The two feed rollers being positively driven and at the same speed produce a
much better feeding action than the positively driven bottom roller and frictionally
driven top rollers hitherto used.
If desired in addition to being supported at both ends the rollers may be supported
at the centre or at suitable distances along their length the same or a similar form
of bearing to that previously described for the ends of the rollers being used.
These improvements are applicable for slubbing, intermediate and roving frames.
Having thus 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:
1st. In drawing slubbing, intermediate and roving frames used in the preparation
of cotton and other fibrous substances the use and employment of feed rollers A

page_text: and B, one or both of which are formed with recesses or narrowed portions E, E
producing openings E', E', or their equivalent, and mounted and arranged
substantially as and for the purposes set forth and illustrated.
