Improvements in and relating to Machines for Winding Yarn.
I, DANIEL MUNSON SEATON, of Soho Mills, Thornton Road, in the City of
Bradford, Machinist, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the construction of a machine by which yarn
may be wound upon a bobbin of varying diameter, such as a conical bobbin, or
upon a parallel bobbin in such a manner that, the yarn is wound thereon at
an equal tension, and so crossed in the winding that, when upon a conical bobbin,
the yarn will not slip in bulk towards the smaller end of the bobbin; and an
unwinding, for the yarn to readily leave the bobbin; also to be enabled to wind
yarn on to bobbins of various lengths and to apply to the machine a device by
which the length of yarn placed upon the bobbin is recorded.
In carrying out my invention, I mount a bobbin between suitable supports
or centres, and when winding upon what I term a conical bobbin, which is also
parallel for a portion of its length, I give to the said bobbin a varying rotary
motion in accordance with the varying diameter of the conical portion of the
bobbin, this varying motion I obtain by conical pullies and a driving belt made
to reciprocate over the said pullies by a movable belt guide operated in accordance
with the traverse of the yarn as it is wound upon the bobbin.
Between the creel or the like and conical bobbin is a tension block or yarn
guide, through which the yarn passes, and is reciprocated a distance equal to the
length of the conical portion of the hobbin by rotating cranks, the pins of which
engage with notched bars, one notched bar moving the tension block or yarn
guide in one direction, and the other notched bar in the other direction, the pins
of the cranks acting on the said bars in such a manner that, the stoppage at the
end of the transverse or stroke on the reversal of the motion is reduced to a
minimum, thereby preventing an accumulation of yarn on the bobbin at each
end of the winding.
The bobbin as the yarn is wound thereon is made to travel slowly in a lateral
direction, this may be accomplished by attaching a cord or the like to one of the
supports carrying the bobbin, and the shaft made to rotate slowly, so that as the
said shaft rotates, the cord or the like is wrapped around same, thereby moving
the support and bobbin in the direction required.
The pins in the before mentioned cranks are adjustable, and notches are cut in
various positions in the before mentioned bars, so that on the regulation of the
crank pins to engage with different notches, the traverse of the tension device or
yarn guide is varied to suit the length of the bobbin placed between the supports
or centres.
When winding yarn upon parallel bobbins, instead of travelling the belt over
the conical pullies, it is retained in one position on the said pullies, thus rotating
the bobbin at one speed, the traverse of the tension block or yarn guide being
operated in the same manner as when winding upon a conical bobbin.

page_text: The measuring of the yarn is accomplished by a series of wheels and pawls, one
wheel is mounted on a shaft, and the others on sleeves supported by the said
shaft, the pawls are reciprocated and the teeth of the wheels are of varying depth
and form, so that one wheel is operated at each pick of the pawls, but the adjacent
wheel is stationary until a complete revolution is made, then it is moved a
distance equal to one tooth by its pawl being allowed to engage therewith, this
is repeated throughout the whole series, and each wheel is combined with a
pointer for registering the rotation and therefore the length of yarn on the
bobbin.

Improvements in and relating to Machines for Winding Yarn.
I, DANIEL MUNSON SEATON, of Soho Mills, Thornton Road, in the City of
Bradford, Machinist, 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 for its object the construction of a machine by which yarn
may be wound upon a bobbin of varying diameter, such as a conical bobbin, or
upon a parallel bobbin in such a manner that, the yarn is wound thereon at an
equal tension and so crossed in the winding that, when the yarn is upon a conical
bobbin, it will not slip in bulk towards the smaller end of the bobbin and on
unwinding, for the yarn to readily leave the bobbin also to so arrange the
traverse that, yarn may be wound upon bobbins of various lengths, and to apply
to the machine a device by which the length of yarn placed upon the bobbins is
recorded.
In describing my invention in detail, reference is made to the accompany-
ing sheets of drawings marked with letters and numerals of reference, and in
which
Fig. 1 represents a side elevation of a winding machine made in accordance
with my invention: the machine shown and herein described is arranged to wind
upon ten bobbins, but it will be obvious to persons skilled in mechanics that a
machine having a greater or less number of bobbins may be constructed with-
out departing from the nature of my invention.

machine, and the recording device removed for more clearly showing the
mechanism below.

a larger scale.
Fig. 6 is a plan of the same.
Fig. 7 is an end elevation.
Fig. 8 is a detached detailed elevation of one of the disc plates with crank pins
for operating the traverse of the yarn carriers, and
Fig. 9 is a detached detailed elevation showing the mechanism for operating the
belt guide.
In carrying out my invention, I place each bobbin A between suitable sup-

page_text: porting shafts or spindles B and C, respectively mounted on the sliding frames 1)
and D, which are connected together by a rod E and supported by longitudinal
bars D2 12, the spindles C being provided with compressed springs S for retaining
the bobbins A in the required position.
The shafts or spindles B are rotary, and motion is communicated thereto by
friction bevel wheels F mounted on the horizontal shafts B and upright shafts F',
to which rotary motion is given in the following manner.
The first or prime mover shaft G of the machine may be driven by a conical
pulley G', or by any other well known form of pulley, and on the shaft G is
secured a spur wheel H gearing into a spur wheel H¹ secured on a shaft carrying
coned pulley G2 connected by belt G to another coned pulley G secured on a
shaft to which is also secured a spur wheel J gearing into a spur wheel J', secured
on a tubular shaft J. The belt G is guided on the conical pullies by a double
forked belt guide K, arranged to engage with the said belt on both sides of the
pullies. One of the rotary shafts or spindles is extended at B₁ for some distance
into the tubular shaft J2, which is arranged with one or more longitudinal
slots J³, with which engages a key of extended shaft B¹, in a manner that, the
said shaft may slide within the tubular shaft J and be rotated thereby; the
extended shaft B₁ transmitting motion to one of the upright shafts F by bevel
wheels F, the said upright shafts being geared together at the bottom by spur
wheels F3.
Upon the tubular shaft J, is secured a worm L gearing into a worm wheel L'
secured on a shaft L, upon which are secured disc plates M M one on each side
of the machine, and each having two pins, which I term crank pins M and M²
attached thereto.
On the rotation of shaft L², the crank pins M and M² engage with the adjust-
able stop pieces N and N¹, N2 and N³, secured on the respective bars N and N³,
placed above and below the shaft L² on each side of the machine.
The bars N and N at each side of the machine are connected together by cross
bars N, one of which at each side of the machine is provided with an adjustable
stud 0, engaging with a slot in the respective swinging arms P, each connected
by a rod P to either of the upright bars P², supported by and secured to the
horizontal sliding bars P3, the upright bars P2 carrying suitable guides Y and
tension blocks for guiding the yarn on to the respective bobbins A as the
upright bars P are reciprocated by the crank pins M1 and M2.
On one of the crank pins M' in each revolving disc plate M engaging with
say the adjustable stop N on the bottom bar N at each side of the machine,
the upright bars P² are moved in the direction of the arrow, thus guiding the
yarn drawn from the creels or the like suitably placed on to the rotating bobbins A
in the direction towards the smaller diameter of same, and when the upright
bars P2 have travelled some distance in the direction indicated, the crank pins M²
engage with the adjustable stop pieces N³, thus continuing the motion of the
upright bars P2, yarn guides Y, and tension blocks Y in the same direction;
then before or about the time the crank pins M² are leaving the adjustable stop.
pieces N3 on the bottom bars No, the crank pins M' will have advanced to engage
with the adjustable stop pieces N' on the top bars N, causing the same and the
upright bars P2 to move in the opposite direction without any perceptible dwell
at the termination of the stroke; the crank pins M2 in turn engage with the
adjustable stop pieces N, thereby continuing the motion of the upright bars P2,
yarn guides Y, and tension blocks Y' in the same direction to the end of the
stroke or traverse, when the operation is repeated.
By regulating the position of the connections between rods P¹ and the swinging
arms P on each side, the length of the traverse is adjusted. The guiding and
building of the yarn on to the rotating bobbins A is effected in a manner that,
the stoppage at the end of the traverse or stroke of the said upright bars P²
on the reversal of the motion is reduced to a minimum, the crank pins in each
dise plate being in such position in relation to each other that, as one crank

page_text: pin in each disc plate M is leaving. the, adjustable stop piece at the termination
of the traverse of the upright, bars P2 in one direction, the other crank pin in
each disc. plate engages with one of, the adjustable stop pieces on the other bar,
say the top bar N4, thus reversing the motion quickly, and thereby preventing an
accumulation of yarn on the bobbins at each end of the winding; and by the yarn
being evenly built on the bobbins A, the tendency.for it to slip is reduced.
The bobbins A are rotated at a varying speed; this is accomplished by travers-
ing the belt G3 by a double forked belt guide K operated by a rotating disc
plate Q, having two crank pins thereon, engaging with adjustable stop pieces Q
and Q similar to those before described, and secured on bars. Q³ and Q, attached
together by cross bars Q and Q (see Fig. 9.) The crank pins R and R! engage
with the adjustable stop pieces Q' and Q2, operating the bars Q³ and Q. in a
longitudinal direction in the same manner as bars N and N3,. and engaging with
a pin in cross bar Q, is a rod S¹ supported at the bottom by a pin. S2, the top, of
the said rod is provided with a projecting pin engaging with a slot in flange K¹
of boss of double belt fork K. The boss of flange K' is carried by a bar K² on
which it is slid by the oscillation of the rod S..
'
By operating the double belt fork K in the manner described, the speed at
which the bobbins A are rotated is always in accordance with the position of the
belt G on the coned pullies G2 and G4, the bobbins A rotating.quickest when the
yarn is being wound upon the small end of the coned bobbins, and slowest at
the base or larger diameter of the cone, thus drawing the yarn from the supply
at an equal rate and tension.
The frames D and D and bobbins A are made to travel slowly in a lateral
direction towards the coned pullies, as the yarn is wound upon said bobbins: this
may be accomplished by attaching a cord or the like to the frame D¹ and to the
shaft T, made to rotate slowly by a train of wheels such as hereinafter described;
or by preference the said lateral motion may be accomplished by securing a
toothed rack T to the said frame D', the rack gearing with the teeth of a
pinion T secured on the before mentioned shaft T, operated by a train of
wheels 1, 2, 3, 4 and 5. which on rotation, moves the frames D and D supporting
the bobbins A in a backward direction towards the before mentioned coned
pullies, thus building the yarn towards the small end of the hobbins.
The wheels are operated by a reciprocating pawl U, actuated in any convenient
manner such as by the rotation of eccentric through the connections and
rocking arms U2 U².
When winding yarn upon parallel bobbins, instead of traversing the belt G³
over the coned pullies G2 and G, the belt is retained in one position on the said
pullies, thus rotating the bobbins at one speed: the traverse of the upright
bars P2 carrying the yarn guides Y, being operated in the same manner as before
described when winding upon coned bobbins.
The measuring of the yarn placed upon the bobbins is accomplished by a
series of ratchet wheels V and, pawls VI, the latter are connected together by a
bar X, and are simultaneously reciprocated by a lever X and rod X2, operated at
intervals through lever X3, by the before mentioned eccentric U on shaft L2.
The number of teeth in each ratchet wheel is preferably ten, one wheel indicat-
ing the units, another the tens, another hundreds, and the fourth wheel thousands;
one tooth space in each of the first three wheels is cut deeper than the rest, so that
for example, every tenth pick of the units ratchet wheel V, pawl engaging there-
with, drops into the deep cut tooth space, allowing the next pawl, that is the
tens pawl, to engage with and operate the ratchet wheel a distance equal to one
tooth, the said tens wheel then remaining stationary until the deep cut units
tooth space again presents itself, when the tens pawl is again allowed to engage
with and operate the tens wheel, which on its tenth operation, the deep cut tooth
spaces of the two first wheels are together, allowing the units and tens pawls to
drop deeper, so that the third pawl representing the hundreds can engage with
and operate its wheel; this is repeated throughout the series, the number of

page_text: reciprocations of the pawls V1 are recorded by the respective ratchet wheels V,
marked with numerals, thus numerically indicating the length of yarn upon each
bobbin; the ratchet wheels V being prevented rotating in the opposite direction
by the pawls W.
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:
1. In a yarn winding machine means for reciprocating the belt guide K, the
belt G over the coned pullies G² and G+, combined with and giving variable
rotary motion to the tubular shaft J, shaft B, and other shafts and rotary con-
nections geared therewith, all arranged substantially in the manner and for the
purpose as herein before set forth.
2. In a yarn winding machine means for rotating the bobbins A, disc plates M,
provided with crank pins, combined with the traversing bars N and N, upright
bars 12 and yarn guides Y, arranged and operated substantially in the manner
and for the purpose as herein before set forth.
3. A winding machine such as hereinbefore described, combined with an in-
dicating device in which are mounted ratchet wheels having some of the tooth
spaces cut deeper than the rest, reciprocating pawls so arranged that no two or
more of the pawls can be engaged with the wheel teeth except when allowed by the
deep cut space or spaces for the purpose as hereinbefore set forth.
