PROVISIONAL SPECIFICATION.
Improvements in Machinery for Preparing and Spinning Cotton
and other Fibres.
I, AUGUSTIN VIMONT, of Vaudry, in the Republic of France, Cotton Spinner,
do hereby declare the nature of this invention to be as follows:-
The object of this invention is to obtain by means of toothed wheels a variation
of rotatory speed of the fluted drawing rollers in proportion to the successive
diameters of the wound cone of thread on the bobbin and, on the other hand, to
improve the process of winding on the bobbin or spindle so as to ease the movement
of the traveller and avoid all contact between the two portions of the thread along
the upper prong of its fork.
To vary the speed of rotation of the fluted rollers proportionately to the varia-
tion in diameter of the conical bobbin I use two eccentrics or cams, the one, which is
toothed, imparts through a train of gears supported in a swing frame a varying move-
ment to one of the gears of an epicyclic or differential mechanism whereby the motion
of the driving shaft is transmitted in varying speed to the fluted drawing rollers;
the other eccentric, which is plain on its periphery controls the movement of the
lifting rail for the distribution of the yarn on the bobbins or spindles.
This mechanism may be combined with that employed generally for forming the
bottom of bobbins at the commencement of taking up; but what I prefer is to give
to the base of the wooden or paper spools the form of the winding cone.
As regards the arrangement for winding in order to avoid the rubbing of the
threads I employ a special traveller forked at one end and preferably with a thin
flat plate at the other, to the upper prong of the fork is attached a hook which
has for its object to isolate completely the thread which comes from the fluted
rollers from that going on to the bobbins. The thread coming from the fluted
rollers is passed under and round the upper prong of the fork and then under the
hook in its passage to the bobbin so that there cannot be any contact of the thread
from the rollers against the same thread passing on to the bobbins which it is
absolutely necessary to attain in order to avoid frequent breaks.
The different portions of the traveller are preferably corrugated to give them
the requisite rigidity, notwithstanding the lightness of the plates of aluminium,
steel, or other metal used in their construction.
The traveller preferably works between two superposed rings the lower ring
serving when necessary as a bearing for its flat or winged end, and while working
a shoulder on the traveller bears against the inner border of the upper ring; it is
therefore important that this ring should be constantly lubricated.
I accomplish this in the following manner :-
On the inner surface of the ring is the end of a small tube connected with an oil
reservoir which is carried in the lifting rail, a cotton wick which is in the tube in
this reservoir carries continually by capillary attraction a small quantity of oil from
the reservoir to the interior of the ring and thus insures a good lubrication. The
same reservoir may serve for several successive rings.

Improvements in Machinery for Preparing and Spinning Cotton
and other Fibres.
I, AUGUSTIN VIMONT, of Vaudry, in the Republic of France, 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 :―
The object of this invention is to obtain by means of toothed wheels a variation
of rotatory speed of the fluted drawing rollers in proportion to the successive
diameters of the wound cone of thread on the bobbin and, on the other hand, to
improve the process of winding on the bobbin or spindle so as to ease the movement
of the traveller and avoid all contact between the two portions of the thread along
the upper prong of its fork.
To vary the speed of rotation of the fluted rollers proportionately to the variation
in diameter of the conical bobbin I use two eccentrics or cams, the one which is
toothed imparts through a train of gears supported in a swing frame a varying
movement to one of the gears of an epicyclic or differential mechanism whereby
the motion of the driving shaft is transmitted in varying speed to the fluted
drawing rollers; the other eccentric, which is plain on its periphery controls the
movement of the lifting rail for the distribution of the yarn on the bobbins or
spindles.
As regards the arrangement for winding in order to avoid the rubbing of the
thread I employ a special traveller forked at one end and preferably with a thin
flat plate at the other, to the upper prong of the fork is attached a hook which
has for its object to isolate completely the thread which comes from the fluted
rollers from that going on to the bobbins. The thread coming from the fluted
rollers is passed under and round the upper prong of the fork and then under the
hook in its passage to the bobbin so that there cannot be any contact of the thread
from the rollers against the same thread passing on to the bobbins which it is
absolutely necessary to attain in order to avoid frequent breaks.
The different portions of the traveller are preferably corrugated to give them the
requisite rigidity notwithstanding the lightness of the plates of aluminium, steel, or
other metal used in their construction.
The traveller preferably works between two superposed rings the lower ring
serving when necessary as a bearing for its flat or winged end, and while working
a shoulder on the traveller bears against the inner border of the upper ring; it is
therefore important that this ring should be constantly lubricated.
I accomplish this in the following manner :-
On the inner surface of the ring is the end of a small tube connected with an
oil reservoir which is carried in the lifting rail, a cotton wick which is in the tube
in this reservoir carries continually by capillary attraction a small quantity of oil
from the reservoir to the interior of the ring and thus insures a good lubrication.
The same reservoir may serve for several successive rings.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying two sheets of drawings reference being had
to the figures and letters marked thereon.
Fig. 1 represents an elevation of part of a bobbin and a ring and traveller
with roving or yarn guided by an ordinary traveller. Fig. 2 is a plan of part
of Fig. 1.
Figs. 3 and 4 are side elevations of my improved differential motion for giving
a variable motion to the fluted drawing rollers of a slubbing, intermediate, roving
or spinning frame.
Fig. 5 is a view of a traveller made according to my invention.

page_text: Fig. 6 is a plan and Fig. 7 a sectional view taken on the line 77 of Fig. 6,
showing the improved traveller Fig. 5 in its working position guiding the roving
or yarn on to a bobbin.
Fig. 8 is a view of a slightly modified form of the traveller shown in Fig. 5.
Referring first to Figs. 3 and 4,-M is the main shaft of the machine which
gives motion to a shaft N by means of a pair of bevel wheels R R' the latter
secured to an inclined shaft R₁ on which is secured a worm V in gear with a
worm wheel X secured to the shaft N; on this shaft are also secured two
similar shaped cams E and Q; the former has spur teeth all round its periphery
while the latter Q has a plain periphery and acts upon a bowl Q₁ carried by a
lever Q2 fulcrumed to the frame at Q and connected by a band Q to a pulley Q';
as the bowl Q₁ is maintained in contact with the cam Q by a spring or weight,
not shown, it follows that the pulley Q is caused to oscillate backwards and
forwards on its axis and the movement of the axis is conveyed in any convenient
manner, not shown, to the ring rail and directs therefore the building of the
successive layers of roving or yarn on the conical bobbins or spools.
The toothed cam E transmits motion by means of a train of spur wheels P,
1, 2, 3, 4, all carried in a swing frame BO suspended from a shaft V on which is
secured a spur wheel P¹ which turns the shaft V' and a wheel P on this shaft
is in gear with and drives a wheel D of a differential motion carried upon a
shaft ; one of the nest of wheels Ku of this differential motion has a long
boss K and is fitted loosely on the shaft F" and on this boss is secured a spur
wheel 7 which is in gear with a carrier wheel 8 which by means of a second carrier
wheel 9 gives the differential motion to a wheel 10 secured upon the axis of one
of the front drawing rollers C whose speed is consequently varied during all the
time that the roving or yarn is being wound on the bobbins or spools.
The pinion P is maintained in constant gear with the cam E by means of a
cam S keyed on the shaft N which acts against a bowl H carried by the swing
frame BO to move it in one direction while gravity moves the frame in the
opposite direction.
To each variation of the diameter of the bobbin (i.e. at each lift of the rail)
produced by the cam Q there is a corresponding variation of speed imparted to
the fluted rollers by the toothed cam E and train of wheels to the fluted roller C ;
as for instance when by means of the cam Q the lifting rail, not shown, brings
the largest diameter of the bobbin in line with the traveller A the cam E
imparts to the fluted roller C its maximum speed and when the cam Q brings the
lifting rail so that the traveller A is opposite the smallest diameter of the bobbin
the toothed cam E imparts to the drawing roller C its minimum speed and the
variations of speed given to the drawing roller will be constantly proportioned
to the increasing diameter of the bobbins, the cams E and Q having the same
contour.
My improved differential motion can be applied to machinery in which spindles
with flyers are employed although I prefer to employ rings and travellers in place
of flyers.
Figs. 1 and 2 represent a ring e and traveller a which form no part of my present
invention but are simply introduced to illustrate a certain defect in the traveller
arising from the fact that the yarn is doubled round one prong and thus rubs
against itself as it is being wound upon the bobbin or spool and the friction thus
caused is very liable to break down and injure the yarn.
In Figs. 5, 6, 7 and 8 are represented my improved form of traveller A. formed
with a hook G and a ridge or neck G' through and round which the roving or
yarn is passed to the bobbin or spool as shown in Figs. 6 and 7 without-in any
way coming in contact with and injuring itself. This traveller is formed preferably
of aluminium or steel corrugated so as to secure strength without undue weight
and has a thin horizontal plate C at the opposite end to the hook which rests
between two rings e el a shoulder d of the traveller coming against the interior
ring e.

page_text: In order to lubricate the traveller I propose to make a small chamber J to form
an oil reservoir in the lifting rail and near each ring, or a single chamber to serve
a number of rings, and a tube J' is fitted in the ring e so that a piece of cotton
wick with one end lying in oil in the reservoir and the other end passed through
the tube carries the oil to the inner portion of a ring and thus lubricates the
shoulder d and plate C.
Having now 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 :-
1. The combination with a cam which is plain on its periphery and through
suitable connections actuates the lifting rail, of a cam of similar contour but toothed
on its periphery which through a train of gears gives a varying motion to one of
the gears of a differential mechanism to vary the speed of the fluted drawing rollers
proportionately to the varying diameter of the conical bobbins all substantially as
and for the purposes herein set forth.
2. The combination with the principal elements specified in Claim 1, of a swing
frame and a separate cam for maintaining the first of the train of gears supported
by said swing frame in gear with the toothed cam E substantially as herein
set forth.
3. The improved traveller formed substantially as shown and described with a
hook G and a ridge or neck G₁ for the purpose of separating and preventing the
yarn from rubbing on itself whilst being wound upon the bobbin or spool.
4. The improved method of and means for lubricating the travellers of preparing
and spinning frames substantially as herein described with reference to Figs. 6
and 7.
