IMPROVEMENTS IN THE CONSTRUCTION OF APPARATUS EMPLOYED IN PREPARING, SPINNING AND DOUBLING COTTON AND OTHER FIBROUS SUBSTANCES
Year: 1884

page_text: I THOMAS FLITCROFT of Middleton in the County of Lancaster Carder do
hereby declare the nature of the said invention for IMPROVEMENTS IN THE
CONSTRUCTION OF APPARATUS EMPLOYED IN PREPARING, SPINNING AND DOUBLING
COTTON AND OTHER FIBROUS SUBSTANCES to be as follows:-
The objects of this invention are to simplify the construction of such machines
or apparatus, by dispensing with a large portion of the gearing, together with the
lifting rails and their differential motion, as usually employed in such apparatus.
The flyers are supported in bearings in a fixed rail at the top and are caused to
revolve by means of endless bands passing from the tin roller round wharves fixed
on or forming part of a boss or sleeve at the top of which is a plate to which the
lower ends of the flyer arms are attached. This boss or sleeve runs loose upon a
stud fixed in the bottom rail.
The top of the spindle runs on a point in the top of the flyer and the bottom of
the same is made with a cup resting upon an india rubber disc at the top of the
fixed stud above mentioned.
The friction between these two surfaces prevents the spindle from revolving with
the flyer excepting as it is compelled to do so by the tension of the yarn.
Working vertically upon the two parallel legs of the flyer is a slide, part of
which carries a tube on the exterior of which is cut a screw thread on which works
the presser which lays the yarn on to the spindle. In this slide works a tee-piece
sliding horizontally and provided with a vertical slot at one end.
Near the bottom of the spindle is fixed a worm gearing with a worm wheel
carried by the flyer and on the side of this wheel is a pin or stud working beneath
the slide and at the same time in the vertical slot in the tee-piece.
As the spindle revolves this pin or stud causes the slide to rise and fall alternately
and thus the presser is caused to guide the yarn onto the spindle.
As soon however as the pin or stud passes over the top centre it allows the slide
to fall the depth of the vertical slot so as to bind the nose of the cop firmly, and
the action of the slot also gives a "dwell" at the bottom before the slide begins
to rise.

page_text: The other end of the tee-piece as it slides to and fro acts upon a ratchet wheel
fixed on the lower end of the screwed tube before mentioned and turns it one
tooth round each revolution of the worm wheel, and by these means the presser
is gradually raised higher and higher so as to build up the cop in the required
manner,
When winding onto a bobbin instead of a cop, the slide and tee-piece will not
be required. The screwed tube on which the presser works is provided with a
double or right and left hand screw and as it is caused to revolve by direct worm
gearing from the spindle it moves the presser up and down and thus lays the
thread evenly upon the bobbin.
.
At the top of the flyer is fixed a worm gearing, with a worm wheel on a
horizontal shaft mounted in bearings on the roller beam. This shaft is provided
with three worms having threads at different angles and driving the three pairs of
drawing rollers at the required differential speeds by means of corresponding worm
wheels; or instead of driving the drawing rollers from the flyers I drive them
from the tin roller by fixing a worm' wheel thereon driving a worm on a vertical
shaft at the top of which is a worm driving a worm wheel on the bottom front
drawing roller, the other rollers being driven 'therefrom by suitable spur gearing.
The fixed stud on which the spindle rests is supported by a spring so as to allow
for doffing.
I, THOMAS FLITCROFT of Middleton in the County of Lancaster Carder do hereby 2
declare the nature of my Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF
APPARATUS EMPLOYED IN PREPARING SPINNING AND DOUBLING COTTON AND OTHER
ور
FIBROUS SUBSTANCES and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:-
The objects of this invention are to simplify the construction of such machines or 3
apparatus, by dispensing with a large portion of the gearing, together with the
lifting rails and their differential motion as usually employed in such apparatus.
Such being the nature and object of my said invention I will now proceed to
describe in detail the manner in which the same is to be or may be performed or
carried into practical effect and in order that the same may be clearly understood 3
I have annexed hereunto a sheet of drawings illustrative thereof and have marked
the same with figures and letters of reference corresponding with those in the
following explanation thereof.
Fig 1, in the annexed drawing is a transverse section of a roving or preparing
frame showing the adaptation of my invention thereto a, a being the end frame
of the machine b, b the drawing rollers, c, c the tin roller and d, d the creel

page_text: One side of the frame is represented as adapted for winding onto cop tubes and
the other side for winding onto bobbins.
Fig. 2. is a front view Fig. 3 an edge view and Fig. 4 a horizontal sectional view
of the cop tube arrangement drawn to a larger scale.
The flyers e, e are supported in bearings f, fin a fixed rail g, g'at the top
and are caused to revolve by means of endless bands h, h passing from the tin
roller c, c round wharves i, i fixed on or forming part of a boss or sleeve k, k at the
top of which is a plate l, to which the lower ends of the flyer arms e, e are
attached. This boss or sleeve, k, k runs loose upon a stud m m fixed in the bottom
rail n n.
The top of the spindle o, o runs on a point p in the top of the flyer. e, e and the
bottom of the same is made with a cup q, q resting upon an india rubber or other
disc at the top of the fixed stud m m above mentioned: or the disc may be
on the bottom of the spindle and the cup on the fixed stud. The friction between
these two surfaces prevents the spindle o, o from revolving with the flyer e, e
excepting as it is compelled to do so by the tension of the yarn.
Working vertically upon the two parallel legs of the flyer is a slide 8, s part of
which carries a tube t, t on the exterior of which is cut a screw thread on which
works the presser u, u which lays the yarn onto the spindle o, o In this slides, s
works a tee-piece v, v sliding horizontally and provided with a vertical slot w, w
at one end.
Near to the bottom of the spindle is fixed a worm x, x gearing with a worm
wheely, y carried by the flyer e, e and on the side of this wheel y, y is a pin, or
stud z working beneath the slide 8, s and at the same time in the vertical slot w,, w
in the tee-piece v, v.
As the spindle o, o revolves this pin or stud z, z causes the slide s, s to rise and
fall alternately and thus the presser u, u is caused to guide the yarn on to the
spindle o, o.
As soon however as the pin or stud ≈, ≈ passes over the top centre it allows the
slide 8, s to fall the depth of the vertical slot w, w so as to bind the nose of the cop
firmly and the action of this slot also gives a dwell" at the bottom before the
slide 8, s begins to rise.
"
The other end of the tee-piece v, v as it slides to and fro acts upon a ratchet
wheel 1, 1 fixed on the lower end of the screwed tube t, t before mentioned and
turns it one tooth round each revolution of the worm wheel y, y and by these
means the presser u, u is gradually raised higher and higher so as to build up the
cop in the required manner.
When winding onto a bobbin as shown on the right hand at Fig. 1. instead of a
cop, the slides, s and the tee-piece v, v will not be required. The screwed tube t¹, th
on which the presser u, u works is provided with a double or right and left hand
screw and as it is caused to revolve by direct worm gearing 2. 2 from the spindle o, o
it moves the presser u, u up and down and thus lays the thread evenly upon the
bobbin 3. 3.
'
At the top of the flyer e, e (see Fig 1.) is fixed a worm 4, 4, gearing with a
worm wheel 5. 5, on a horizontal shaft 6, 6, mounted in bearings on the roller
beam 7. 7.
This shaft 6. 6 is provided with three worms 8. 8, 8, having threads at different
angles and driving the three pairs of drawing rollers 9. 9: 9. at the required
differential speeds by means of corresponding worm wheels 10. 10. 10.
Or instead
of driving the drawing rollers from the flyers I drive them from the tin roller by a
combination of bevil wheels and worm gearing as shown by the dotted lines 11. 11.
in Fig 1.
The fixed stud m m on which the spindle rests is supported by a spring so as to
allow for doffing.
Figs 5 and 6 are front and side views of a modification of the spindle and flyer
arrangement when winding on a cap.

page_text: Instead of, mounting the pin z upon the worm wheel I fix it on- an excentric
and eliptical toothed wheel x, x¹ gearing into an excentric toothed wheel y', y¹
revolving on the shaft of the worm wheel y, y, this will lift the slotted piece t¹¹, t
which in its turn will lift the tube t, t, as it slides up and down and this excentric
gearing will give a quick fall to the presser uu and bind the nose of the cop
without the use of the tee pièce v, v before described.
: In order to actuate the ratchet wheel 1. 1. the boss of the excentric eliptical
toothed wheel is provided with a projection s¹, which moves the ratchet wheel 1. 1.
at each revolution of the said wheel x1, x¹, sufficiently to cause the tube t, t to lift
the presser u, u as before described.
The. tube t, t is provided with a pin t¹, t¹ which works in a grooved cut round
the upper part of the slotted piece t¹¹, t¹ and thus it can be lifted thereby and be
free to revolve at the same time.
I would here remark that I have illustrated and described two methods of
driving the rollers, but other convenient means may be devised for driving these
rollers either from the flyer or the tin roller shaft as may be preferred.
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
First the particular construction of the flyer and the arrangement of parts
constituting the mechanism for actuating the presser arm of the same so as to
guide the thread onto the bobbin or spool in the required form and Secondly.
I claim the mechanism for actuating the drawing rollers of such machines by
means of worm gearing actuated from the tin roller shaft, all being constructed
and arranged substantially as herein before more particularly set forth and described
and illüstrated by the drawings annexed whereby I-am enabled to simplify the
construction of, the machines by dispensing with a large portion of the gearing
together with the lifting rails and their differential motion as usually employed
in such apparatus.
