IMPROVEMENTS IN OR APPLICABLE TO SPINNING, SLUBBING AND ROVING FRAMES
Year: 1885

I AUGUST DILTHEY, of Rheydt, in the Province of the Rhine, Prussia, Cotton
Spinner, do hereby declare the nature of the said invention for "IMPROVEMENTS
IN OR APPLICABLE TO SPINNING, SLUBBING AND ROVING FRAMES," to be as
follows:-
My invention relates to the arrangement and weighting of the top drawing
rollers of spinning, slubbing and roving frames.
In the common arrangement the two end pivots of each roller have bearings in
the "cap bar," and each roller is weighted by a hook which takes upon a bearing
in the middle of the roller, so that each roller has thus three points of friction
when rotating-My invention consists in applying a bearing to each end pivot of
the roller, this, bearing being of suitable shape to fit the slot or recess in the cap
bar which will hold and prevent the bearing from rotating but leave it free to rise.
and fall in the slot or recess in the cap bar as required in working. -
0
The pivots of the roller are free to rotate in the bearing, and a hole is or may
be formed in each bearing to lubricate the pivot..
Each end of the roller is or may be undercut to form an annular space round
each pivot and the bearing is or may be made to pass into and fit this annular
space which will thus prevent dirt or "fly" or fibre from getting between the pivot
and the bearing.
d
The roller is weighted in my improved arrangement by a hook, the end of which
is or may be made to hook in the cup or cavity formed in each bearing for the oil
and so as to wholly or partly cover the oil hole or cavity; or the hook, is or may
be otherwise connected with the said bearing in the cap bar.
.
I
A separate weight is or may be suspended on each hook or the two hooks at the
lower end are connected with a cross bar upon the middle of which a weight is
suspended, so that both ends of the roller, are equally weighted by one weight, at
the same time each end is separately free to rise or fall as required.

Roving Frames.
I AUGUST DILTHEY of Rheydt. in the Province of the Rhine, Prussia, Cotton
Spinner 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 :—
'
My invention relates to the arrangement and weighting of the top drawing
rollers of spinning slubbing and roving frames.
In the common arrangement the two end pivots of each roller have bearings in
the "cap bar" and each roller is weighted by a hook which takes upon a bearing
in the middle of the roller, so that each roller has thus three points of friction
when rotating-My invention consists in applying a bearing to each end pivot of
the roller, this bearing being of suitable shape, to fit the slot or recess in the cap
bar which will hold and prevent the bearing from rotating but leave it free to rise
and fall in the slot or recess in the cap bar as required in working.
The pivots of the roller are free to rotate in the bearing, and a hole is or may be
formed in each bearing to lubricate the pivot.
Each end of the roller is or may be undercut to form an annular space round
each pivot and the bearing is or may be made to pass into and fit this annular
space which will thus prevent dirt or "fly" or fibre from getting between the pivot
and the bearing.
The roller is weighted in my improved arrangement by a hook the end of which
is or may be made to hook in the cup or cavity formed in each bearing for the oil
and so as to wholly or partly cover the oil hole or cavity; or the hook is or may
be otherwise connected with the said bearing in the cap bar.
A separate weight is or may be suspended on each hook or the two hooks at the
lower end are or may be connected by wires extending below the roller beam with
a cross bar upon the middle of which a weight is suspended or the wires are
connected with the two ends of a weight extending between the wires so that both
ends of the roller are equally weighted by one weight, at the same time each end
is separately free to rise or fall as required.
Figs. 1 and 4 are longitudinal sections of top rollers having bearings according
to my invention one (fig. 1) being suitable for spinning, and the other (fig. 4) for
preparing.
Figs. 2 and 5 are plan views of the same rollers as they appear when placed in
the grooves or slots in the cap bars, parts of which are shown, and figs. 3 and 6 are
'views of one end of the rollers and their bearings with the weight hook applied to
the bearing.
a is a top drawing roller for preparing and spinning machinery the bosses of
which are covered with flannel and leather as usual-Its end pivots a¹ are each
made to fit a bearing & of the shape shown in the drawings, and each end of the
roller round the pivots is or may be recessed as shown, so that the bearing b which
is or may be of cone form externally, at one side, and may enter the said conical
recess.

page_text: There is or may be an oil hole 61 in each bearing b which comes or may come
opposite a groove a² formed round the pivot of the roller at each end.
The bearings bare square or oblong or of other suitable shape and fit so as to
slide freely up and down in the slots in the cap bars c and the weight or pressure
is brought upon both ends of each roller by hooks, one at each end, the upper end
of the hook f fits and enters the hole 6¹ for oil in the bearing and the lower end of
the hook fis connected with the weight, or weight lever, or other suitable arrange-
ment for pressing the top rollers against the bottom rollers.
The hooks rest or may rest on a groove g in the bearing b as shown by f¹ fig. 6
and each bearing has or may have a oil hole b¹.
With my improvements each top roller has only friction at its two ends, and not
both at its two ends and in the middle as in the ordinary arrangement.
There are no open bearings as in the ordinary arrangement for dirt and waste
to get into and accumulate upon, and the rollers are thus not likely to become
obstructed in their rotation and so produce uneven sliver, yarn or thread-They
require less cleaning and also require less oil and it is retained in the bearings and
lasts longer and the rollers rotate with less friction and more evenly, compared with
ordinary top rollers, or the "Evan Leigh" loose boss top rollers.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, "I declare that what
I claim is,"
The construction, combination and arrangement of top drawing rollers for
preparing and spinning machinery with a bearing at each end which is combined
with and can slide freely up and down in the slots of the cap bars for top rollers,
and which bearings have pressure put upon them by hooks resting upon the said
bearings substantially as herein before described and illustrated by the drawings.
