Improvements in or relating to the Drawing Rollers of Slubbing,
Intermediate, Roving, and other similar Machines employed in
the Spinning of Fibrous Materials.
I, JAMES PILLING, of 12 Richmond Terrace, Accrington, in the County of
Lancaster, Mechanic, do hereby declare the nature of this invention to be as
follows:-
This invention has reference to the drawing rollers used in slubbing, inter-
mediate, roving and other similar machines employed in the spinning of fibrous
materials, to attenuate or draw out the sliver.
Its object is to provide for the more ready adjustment of the several parts when
varying the distance between the drawing rollers as may be required.
It consists essentially in mounting or pivoting the bearings carrying the
extremities of the back and intermediate drawing rollers, and the carrier wheel
which conveys or transmits motion from the back roller to the intermediate roller,
on one stud or spindle which will be capable of adjustment as the distance between
the drawing rollers may be varied, and so maintain the carrier wheel at a fixed or
constant distance from the centres of the drawing rollers.
In carrying out the invention I form a slot or hole in the side of the bracket
carrying or supporting the gearing through which the motion is conveyed from the
frout to the back drawing roller. This slot may be formed of elliptical shape so as
to permit of a slight adjustment in either a vertical or horizontal direction of a
stud or spindle on which is mounted or carried the bearings or brackets for the
drawing rollers, though it may be circular or of other suitable shape. The stud or
spindle will preferably be formed at its end furthest from the bracket of a size to
permit of the free rotation of the carrier wheel thereon and then of a somewhat
reduced circumference thereby forming a collar or shoulder. Between this shoulder
and the inside of the bracket the bearings for the spindles of the drawing rollers
are held by a washer and nut screwed on the outer extremity of the stud or spindle.
The bracket will be formed on its upper edge with a horizontal rib or flange upon
which a collar on the bearing of the back roller will rest. In addition to relieving
the stud or spindle of the weight of the carrier wheel and the bearings or brackets
this will necessitate the drawing rollers when being adjusted moving in a horizontal
plane. The bearing or bracket carrying the back drawing roller will preferably
be made with a hole of a diameter somewhat exceeding the diameter of the stud cr
spindle and the bearing or bracket of the intermediate roller with a hole approx:-
mately of the same diameter as the spindle. It will also be provided with a
projecting ring which passes into the hole in the bearing of the back roller and
upon which ring the back roller bearing or bracket rotates.
It will be obvious that the carrier wheel is constantly maintained in contact with
the gear wheels on the back and intermediate drawing rollers.
In adjusting the drawing rollers the nut will be slackened on the end of the
spindle passing through the bracket thus permitting of the drawing rollers being
adjusted inwardly or outwardly as may be required, the spindle accommodating
itself thereto in the slot or hole in the bracket. When the desired adjustment has
been made the nut is again tightened and holds the bearings in the required

page_text: position by clamping them between the bracket and the collar or shoulder on the
spindle.

Improvements in or relating to the Drawing Rollers of Slubbing.
Intermediate, Roving, and other similar Machines employed in
the Spinning of Fibrous Materials.
JAMES PILLING, 12 Richmond Terrace, Richmond Hill, Accrington, Machine
Fitter, 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 has reference to the drawing rollers used in slubbing, intermediate.
roving and other similar machines employed in the spinning of fibrous materials, to
attenuate or draw out the sliver.
Its object is to provide for the more ready adjustment of the several parts when
varying the distance between the drawing rollers as may be required.
It consists essentially in mounting or pivoting the bearings carrying the
extremities of the back and intermediate drawing rollers, and the carrier wheel
which conveys or transmits motion froin the back roller to the intermediate roller,
on one stud or spindle which will be capable of adjustment as the distance between
the drawing rollers may be varied, and so maintain the carrier wheel at a fixed or
constant distance from the centres of the drawing rollers.
In carrying out the invention I form a slot or hole in the side of the bracket
carrying or supporting the gearing through which the motion is conveyed from the
front to the back drawing roller. This slot may be formed of elliptical shape so as
to permit of a slight adjustment in either a vertical or horizontal direction of a stud
or spindle on which is mounted or carried the bearings or brackets for the drawing
rollers, though it may be circular or of other suitable shape. The stud or spindle will
preferably be formed at its end furthest from the bracket of a size to permit of the
free rotation of the carrier wheel thereon and then of a somewhat reduced cir-
cumference thereby forming a collar or shoulder. Between this shoulder and the
inside of the bracket the bearings for the spindles of the drawing rollers are held
by a washer and nut screwed on the outer extremity of the stud or spindle. The
bracket will be formed on its upper edge with a horizontal rib or flange upon which
a collar on the bearing of the back roller will rest. In addition to relieving the
stud or spindle of the weight of the carrier wheel and the bearings or brackets this
will necessitate the drawing rollers when being adjusted moving in a horizontal
plane. The bearing or bracket carrying the back drawing roller will preferably be
made with a hole of a diameter somewhat exceeding the diameter of the stud or
spindle and the bearing or bracket of the intermediate roller with a hole
approximately of the same diameter as the spindle. It will also be provided with
a projecting ring which passes into the hole in the bearing of the back roller and
upon which ring the back roller bearing or bracket rotates.
It will be obvious that the carrier wheel is constantly maintained in contact with
the gear wheels on the back and intermediate drawing rollers.
In adjusting the drawing rollers the nut will be slackened on the end of the
spindle passing through the bracket thus permitting of the drawing rollers being
adjusted inwardly or outwardly as may be required, the spindle accommodating
itself thereto in the slot or hole in the bracket. When the desired adjustment h: s
been made the uut is again tightened and holds the bearings in the required

page_text: understood I make reference to the accompanying sheet of drawings.
Fig. 1 shows a frout elevation of the parts belonging to my invention.
Fig. 2 is an end elevation.
Fig. 3 is a plan view.
Fig. 4 is a sectional elevation.
In Fig. 1 are the bearings A and B. The bearing A supporting the intermediate-
roller C and the bearing B supporting the back roller D. Both these bearings are
pivoted on the stud E and are held or clamped to the slotted bracket F by the
nut G.
Mounted on the stud E is shown a carrier wheel H which gears with the wheel.
on the intermediate roller C and with the wheel K on the back roller D. On the
top of the bracket F are shown the ribs or flanges L and M.
The collar N of the bearing A is shown resting on the rib or flange L and the
collar of the bearing B is shown resting on the rib or flange M.
on the
In Fig. 2 is shown the carrier wheel H in gear with the wheel
intermediate roller C and in gear with the wheel K on the back roller D.
When the distance between the centres of the rollers C and D is varied the
carrier wheel II is always kept in gear with the wheels on these rollers, owing to it
being mounted on the stud E which is always at a constant or fixed distance from
each of the rollers. The stud is kept at a fixed distance from each of the rollers
owing to being mounted in a hole in each of the bearing brackets A and B, this
hole being the gearing distance from the centre to centre of the roller in both
bracket or bearings. A slot P is shown in the bracket F and this slot is made
sufficiently large so as to allow a free movement of the stud E when the distance
between the rollers is altered. Collars N and O of the bearings A and B are shown
resting on the ribs L and M formed on the top of the bracket F. These ribs
besides helping to carry the weight of the bearing brackets A and B the stud E
and the carrier wheel H form guides so as to keep the rollers always in same plane
when the distance between their centres is altered. Fig. 4 is a sectional elevation
showing how the bearing brackets A and B are held in position by being clamped to
the faces of the slotted bracket Fand between the shoulder Q formed on the stud E
and the nut G. The carrier wheel H is also shown mounted on the stud E.
Having now particularly described and ascertained the nature of this my inven-
tion and in what manner the same is to be performed I declare that what I
claim is.
Firstly. The mounting of drawing rollers, such as used in roving and slubbing
frames having adjusting bearing brackets carrying and maintaining the position of
the distance of the carrier wheel H draw rollers C and D being held in proper
gearing distance from the carrier wheel H in all the adjustable positions for which
the draw rollers may be required or set apart from each other.
Secondly. The bolt or stud E on which the carrier wheel H is mounted being
made use of for the purpose of securing the adjustable brackets carrying the drawing
rollers in any predetermined position.
Thirdly. The supporting ribs shown on the upper part of bracket F which give
support to the draw roller brackets A and B and to give assurity of the draw
roller moving on the same plane as the other bearings require, as illustrated and
described.
