We, HUBERT JOSEPH BOUFFIOux, of Genappe, in the Kingdom of Belgium,
Twister, and JEAN FRANCOIS GERARD, of Wauthier-Braine, in the Kingdom of
Belgium, Spinning Mill Proprietor, do hereby declare the nature of this inven-
tion to be as follows:
This invention has for its object an improved bobbin winder which may be
used for cotton wool and flax.
This bobbin winder is chiefly characterized by the use of a winding roller having
the shape of a truncated cone the axis of which has a twofold inclination relatively
to the axis of the bobbin; besides the inclination necessary to allow the roller to
be in contact with the bobbin or with the layers of roving or thread coiled thereon
this roller has another inclination which has the effect of causing it to rise while
turning according as the layers of thread are formed without exerting thereon
any injurious pressure and without production of undue sliding friction and con-
sequent gloss on the thread the absence of these being due to the rotary motion
of the roller.
In order to thoroughly explain the latter inclination we will describe it with
reference to Figures 1 and 2 of the accompanying drawings, in which G is the
winding roller and A the bobbin.
If it be supposed that a plane passes through the axis y, y' of the bobbin spindle
perpendicularly to the plane of Figure 1, the axis X, X of the roller will be
situated in another plane likewise perpendicular to the plane of Figure 1, but
intersecting the first mentioned plane on the line m, n the projection of which
will be at K. The axis X X' will intersect m n at O. The half plane X () m
will make with a horizontal plane passing through the intersection m, n an angle
of 90°
+ a (see Figure 1) if the winding of the thread be from right to left of
the bobbin or of 90°
if the winding be from left to right. It would be
easy to demonstrate that if this condition were not fulfilled, the roller instead
of ascending, would have a tendency to descend or to remain stationary.

We will now describe the apparatus with reference to Figures 3 and 4 which
illustrate the same in front and side views respectively.
The roller is mounted in such a manner that the inclination of its axis may be
regulated or adjusted in every direction, between the arms of a piece H which
is capable of sliding along a rod T the two ends of which are fixed to a lever L
capable of oscillating on an axis B. To the lower end of this lever L is jointed
a hand lever S furnished with two notches e and el designed for engagement with
a stop bar fixed to the spindle carrier. When the lever S is moved so that the
stop bar u engages in the notch e the lever L and the roller G are moved away
from the bobbin into the non-acting position and when the lever S is engaged
with the stop bar u by means of the notch el, the roller G bears lightly against the
bobbin. The thread in coiling on the bobbin has a tendency to push away from
it the roller G which, owing to the inclination above mentioned ascends while turn-
ing around its axis

page_text: The roller G and its sliding support H are balanced by a counterpoise which
is connected thereto by a cord passing over a pulley R at the upper end of the
lever L. The weight of the counterpoise p may be varied according as the thread
on the bobbin is required to be more or less compact.
For regulation of the position of the thread guide f the sliding bar H carries
a lug g to which is fixed à bent rod t, t¹ the end of which projects under the thread
guide f which slides vertically on a rod d fixed to the carrier K which has an up
and down motion as in other arrangements of bobbin winders. The sliding socket
of the thread guide f is furnished with a spring which bears on the rod d and
prevents the thread guide from sliding upon the said rod by gravity. When the
thread guide in following the motion of the carrier K meets in its descent the
rod t, t, the said rod prevents it from going farther and the rod then slides
within the socket of the thread guide until the descent of the carrier K ceases
and the thread guide is held in the position which it then occupies on the rod d
until the rod t, t¹ again impedes its descent with the carrier K. Thus while con-
stantly following the travel of the carrier the point from which ascent of the thread
guide begins is determined according to the formation of the successive layers of
thread on the bobbin.
To bring the thread guide to the starting point the spring is drawn slightly
away from the rod d and the thread guide is lowered to the required point.
Where a spindle is not provided for supporting the bobbins, the upper arm of
the slide H is furnished with a socket g which prevents vibration. Paper tubes
may be used.

improvements in Bobbin Winders.
We, HUBERT JOSEPH BOUFFIOUX, of Genappe, in the Kingdom of Belgium,
Twister, and JEAN FRANCOIS GERARD, of Wauthier-Braine, in the Kingdom of
Belgium, Spinning Mill Proprietor, do hereby declare the nature of this inven-
tion 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 for its object an improved bobbin winder which may be
used for cotton wool and flax.
:
This bobbin winder is chiefly characterized by the use of a winding roller having
the shape of a truncated cone the axis of which has a twofold inclination relatively
to the axis of the bobbin besides the inclination necessary to allow the roller to
be in contact with the bobbin or with the layers of roving or thread coiled thereon
this roller has another inclination which has the effect of causing it to rise while
turning according as the layers of thread are formed without exerting thereon
any injurious pressure and without production of undue sliding friction and con-
sequent gloss on the thread the absence of these being due to the rotary motion
of the roller.
In order to thoroughly explain the latter inclination we will describe it with
reference to Figures 1 and 2 of the drawings accompanying our Provisional
Specification in which drawings G is the winding roller and A the bobbin.
If it be supposed that a plane passes through the axis y, y' of the bobbin spindle
perpendicularly to the plane of Figure 1, the axis X, X of the roller will be
situated in another plane likewise perpendicular to the plane of Figure 1 but

page_text: intersecting the first mentioned plane on the line m n the projection of which
will be at K. The axis X X¹ will intersect m n at O. The half plane X 0 m
will make with a horizontal plane passing through the intersection m n an angle
of 90° a
(see Figure 1) if the winding of the thread be from right to left of
the bobbin or of 90° - a if the winding be from left to right. It would be
easy to demonstrate that if this condition were not fulfilled the roller instead
of ascending would have a tendency to descend or to remain stationary.
We will now describe the apparatus with reference to Figures 3 and 4 which
illustrate the same in front and side views respectively.
The roller is mounted in such a manner that the inclination of its axis may be
regulated or adjusted in every direction between the arms of a piece H which
is capable of sliding along a rod T the two ends of which are fixed to a lever L
capable of oscillating on an axis B. The means of adjustment illustrated con-
sist of slotted plates W and W secured to the arms of the piece H by bolts
passing through the slots. To the lower end of this lever L is jointed,
à hand lever S furnished with two notches e and e¹ designed for engagement with
a stop bar u fixed to the spindle carrier. When the lever S is moved so that the
stop bar u engages in the notch e, the lever L and the roller G are moved away
from the bobbin into the non-acting position and when the lever S is engaged
with the stop bar u by means of the notch e the roller G bears lightly against the
bobbin. The thread in coiling on the bobbin has a tendency to push away from
it the roller G which, owing to the inclination above mentioned ascends while turn-
ing around its axis.
The roller G and its sliding support H are balanced by a counterpoise which
is connected thereto by a cord passing over a pulley R at the upper end of the
lever L. The weight of the counterpoise p may be varied according as the thread
on the bobbin is required to be more or less compact.
For regulation of the position of the thread guide f the sliding bar H carries
a lug g to which is fixed a bent rod t t the end of which projects under the thread
guide f which slides vertically on a rod d fixed to the carrier K which has an up
and down motion as in other arrangements of bobbin winders. The sliding socket
of the thread guide f is furnished with a spring r which bears on the rod d and
prevents the thread guide from sliding upon the said rod by gravity. When the
thread guide in following the motion of the carrier K meets in its descent the
rod t the said rod prevents it from going further and the rod d then slides
within the socket of the thread guide until the descent of the carrier K ceases
and the thread guide is held in the position which it then occupies on the rod d
until the rod t again impedes its descent with the carrier K. Thus while con-
stantly following the travel of the carrier, the point from which ascent of the thread
guide begins is determined according to the formation of the successive layers of
thread on the bobbin.
T
To bring the thread guide to the starting point the spring is drawn slightly
away from the rod d and the thread guide is lowered to the required point.
The weight of the bobbin A which is borne by the part a' affixed to the spindle a
ensures rotation of the bobbin with the spindle.
Where a spindle is not provided for supporting the bobbin, the socket y on the
upper arm of the slide H suffices to prevent vibration of the bobbin which may
be driven by the usual means. Paper tubes may be used.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that
we claim:
First: A bobbin winder characterized by a roller having the shape of a trun-
ented cone and regulating the winding and tightness or compactness of the thread
on the bobbin and the position of the thread guide, this roller being doubly
nclined relatively to the bobbin in such manner as to be in contact therewith
or with the layers of thread wound thereon and also in such manner as to rise while

page_text: turning according as the layers of thread are formed, the moveable support of the
roller carrying a rod which advances under the upwardly and downwardly move-
able thread guide to limit its downward motion substantially as hereinbefore
described and illustrated in the accompanying drawings.
Secondly: An arrangement of the bobbin winder defined in the foregoing
claim consisting in mounting the doubly inclined roller G between the arms of
a support H sliding upon a rod T and more or less balanced by a counterweight p
and in fixing to the support H a rod t t¹ the free end of which moves towards the
sliding thread guide f working on a rod d' which moves up and down with the
carrier K; the thread guide f being furnished with a spring r which prevents it
from sliding by gravity upon the rod d and the roller & being capable of being
placed in contact or out of contact with the bobbin A by causing the lever L carry-
ing the rod T and the balanced sliding support H to oscillate upon its axis B sub-
stantially as herein before described and illustrated in the accompanying drawings.
