PROVISIONAL SPECIFICATION
Improvements in Drawing, Slubbing, and other Frames for preparing
Fibrous Materials for Spinning.
We, SAMUEL HERBERT BROOKS of the Firm of Brooks & Doxey, Union Iron
Works, West Gorton, Manchester in the County of Lancaster, Machine Makers, and
JOHN SAMUEL BROOKS of the Union Iron Works aforesaid, Sub-manager, do hereby
declare the nature of this invention to be as follows:-
This invention relates to those top rollers of drawing slubbing and other frames
which are used as "single" preventors and is designed to provide means for preventing
lateral movement of these rollers and also for dividing or separating the slivers
passing under them.
Hitherto it has been customary to obtain this result either by grooving the
bottom rollers or by forming a collar or shoulder thereon which is objectionable for
many reasons.
We now find that this can be done without in any way altering the bottom
rollers and without interfering with the ends of the top rollers.
We employ two bottom or driving rollers and resting above these is placed the
top rollers of larger diameter and bearing upon both. In each top roller we cut (or
otherwise form) an annular groove at or about the centre of its length. This groove
is of any convenient or suitable depth to engage with a curved finger projecting over
one of the bottom rollers.
Below the rollers we place a bar or rod running longitudinally of the frame and
parallel with the rollers. At intervals along this bar we place a number of curved
fingers which pass up from the rod and project over the top of the bottom rollers.
The number of these curved fingers corresponds with the number of top rollers
and the end of each engages with the annular groove in one of the rollers.
The top, rollers are maintained parallel with the bottom rollers by their position
resting between the two and are prevented moving laterally by the curved finger
engaging with the groove and the curved finger also serves to divide or separate the
slivers to prevent one running into another.
In lieu of the. bar for carrying the curved fingers they may be placed on the
"back" plate over which the slivers pass or in any other convenient position which
will allow these fingers to act as a divider of the slivers and at the same time
prevent lateral movement of the top roller.

We, SAMUEL HERBERT BROOKS, of the Firm of Brooks and Doxey, Union Iron
Works West Gorton, Manchester, in the County of Lancaster, Machine Makers, and
JOHN SAMUEL BROOKS of the Union Iron Works aforesaid, Sub-manager, 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 :-
This invention relates to those top rollers of drawing, slubbing and other frames
which are used as "single" preventors, and is designed to provide means for
preventing lateral movement of these rollers, and also for dividing or separating
the slivers passing under them.
Hitherto it has been customary to obtain this result, either by grooving the bottom
rollers, or by forming a collar or shoulder thereon, which is objectionable for many
reasons.
We now find that this can be done without in any way altering the bottom rollers,
and without interfering with the ends of the top rollers.
The invention consists essentially in applying to two bottom or driving rollers,
a top roller of larger diameter, bearing upon both bottom rollers, provided with
a central groove, and held in position from lateral movement by a curved finger,
which enters the groove, and also serves to divide the slivers.
It will be fully described with reference to the accompanying drawings, in which
sufficient of a drawing frame is shown to illustrate our invention.
Fig. 1. End elevation, partly in section.
Fig. 2. Back elevation.
The two bottom or driven rollers A are of ordinary construction, and resting upon
these two we employ a single top roller B of much larger diameter, which bears
against both.
In each top roller B we cut (or otherwise form) an annular groove b at or about
the centre of its length. This groove is of any convenient or suitable depth to
engage with a curved finger C, projecting over one of the bottom rollers.
Below the rollers, we place a bar or rod D, running longitudinally of the frame,
and parallel with the rollers. At intervals along this bar we place a number of
curved fingers C, which pass up from the rod, and project over the top of the bottom
rollers. The number of the curved fingers C corresponds with the number of
top rollers B, and the end of each engages with the annular groove b in one of the
rollers.
The top rollers B are maintained parallel with the bottom rollers A by their
position, resting between the two, and are prevented moving laterally by the curved
finger C, engaging with the groove b. The curved finger also serves to divide or
separate the slivers E, to prevent one running into another.
In lieu of the bar D for carrying the curved fingers, they may be placed on the
"back" plate F, over which the slivers E pass, or in any other convenient position
which will allow these fingers to act as a divider of the slivers, and at the same time
prevent lateral movement of the top roller.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
In a drawing, slubbing, or other frame for preparing fibrous materials for
spinning, the combination with double bottom rollers, such as A, of a single top

page_text: roller of larger diameter bearing upon both, provided with an annular groove, and
a projecting finger C which engages with the groove in the top roller and prevents
lateral movement thereof, substantially as described.
