6 Claims.

This invention relates to winding machines for winding yarn with what is commonly referred to as the open wind or Foster wind on cores of cones, tubes and the like and wherethe cone or tube produced by the machine is known as a package, and in particular a yarn winder that winds yarn evenly with the yarn tight at the ends and also throughout the intermediate portions of the cones or tubes.

The combination of the continuously traveling yarn guide on the traverse with large cylinders. and with the tubes and cones driven by surface contact with the cylinders makes it possible to wind, at high speeds, the same number of yards of yarn per minute continuously and eliminate building up or ribboning.

In winding yarn With conventional winders the speed of winding is limited to a safe operating speed of the traverse and yarn guide, operated by the traverse; as in reversing the direction of travel of the guide it is necessary for the guide to stop and start back in the opposite direction.

The quantity of yarn wound by machines of this type is, therefore, controlled by the operation of the traverse. The yarn is fed from the yarn guide to tubes and cones over a cylinder, and with the surface of the cylinder contacting the peripheral surface of a cone or tube, the surface speed of the cone or tube corresponds with that of the cylinder.

Increasing the diameter of the yarn feeding cylinder, therefore, makes it possible to speed up yarn winders for this use whereby the quantity of yarn wound on a winder is increased from that of conventional winders.

In addition to speeding up the quantity of yarn wound per day the large feeding cylinder in combination with the yarn guide and traverse wherein the yarn guide is actuated by the traverse makes it possible to obtain an even tight wind with all spongy portions, particularly at the ends, eliminated and with the breaking of the yarn reduced to a minimum.

The purpose of this invention is to improve yarn winding machines and provide a machine which winds the yarn with a smooth easy pull on the yarn whereby maximum tension may be used and wherein cones or tubes formed on the machine are firm throughout the intermediate parts and also at the ends thereof.

With the conventional method of winding yarn to form cones and tubes, the yarn winds tight or firm at the center or through the intermediate reverse action at the ends the ends are soft or 2 spongy and this makes it difficult to feed the yarn evenly from the spools, cones, or tubes on unwinding.

With this thought in mind this invention contemplates a winder including the combination of grooved cylinders and a traverse, in which the traverse is provided with a traveling thread guide which carries the yarn and lets the yarn fall into grooves at each of the ends of the cylinders in each revolution of the cylinders whereby the length and size of the package is substantially unlimited.

The object of this machine is, therefore, to provide means for maintaining constant and maximum tension on yarn being wound on cones and tubes whereby the cones and tubes are tight and firm throughout the length thereof.

Another important object of the invention is to increase the diameter of the yarn feeding cylinders of winding machines whereby the surface speed ofv the cylinder is increased while the yarn vided for stopping the operation of the machine as the yarn breaks.

Another obiect of the invention is to provide an improved yarn winding machine wherein finished cones or tubes are automatically elevated when completed.

A further object of the invention is to provide an improved machine for winding cones, tubes, and the like with the cones, tubes and the like firm throughout the length thereof, in which the machine is of a simple and economical construction.

With these and other obiects and advantages in view the invention embodies a frame having a traverse cylinder shaft journaled therein. a plurality of cone and tube carrying spindles journaled in arms and positioned whereby cones and tubes formed thereon are aligned with and contact the surfaces of the traverse cylinders and means for rotating the parts and elevating the spindles when a strand of yarn breaks and also as the cones or tubes are filled.

Figure 1 is a detail showing a section through part of the cylinder with which the thread is fed to cones and tubes and showing the thread return groove that is provided at each end of the cylinder.

Referring now to the drawings wherein like reference characters denote corresponding parts the improved cone and tube winder of this invention includes a frame, generally indicated by the numeral it. a traverse or grooved cylinder 1 i mounted on a shaft l2, a traverse arm l3 having a base it and reciprocated by a bar 55, a ratchet it which is actuated by a pawl ii, the movement of which is controlled by a yarn engaging lever 18, and a yoke 15 in the end of arms 2!! and 2| of which cones or tubes, as indicated by the numeral 22 are held for winding.

Yarn, as indicated by the numeral 23 is fed from a bobbin 24 through a tension 25 from which the yarn passes through an eye it on the end of the traverse arm is to grooves 2? of the cylinder It and from the cylinder the yarn is fed back and forth across the surface of a core 28 which is freely held in the yoke i9.

Should the yarn break, the lever it moves u wardly allowing the pawl H to engage the ratchet 56, causing the ratchet to rotate counterclockwise to a point where an end 25 of the lever 23 engages the teeth of the ratchet i5. locking the ratchet.

With the ratchet is turning counterclockwise a chain 30, attached to the ratchet at tl e point %i and trained over a sprocket 32 on the yoke i9, turns the sprocket whereby a cone or tube in the arms of the yoke is moved upwardly away from the surface of the cylinder so that rotation of the cone or tube ceases.

In the same movement a chain attached to the ratchet it at the point at one end to a lever at the other, actuates the lever 35 about a pivot illustrated in 7, 8 and 9 so that a pin 3'5, extended through a slot 38 in the base M of the traverse arm It moves the pin 31 with the bar 39 from which the pin extends upwardly whereby a ball i6 on the lower end of the bar 39 moved upwarcly out of a socket ii in the bar is so that movement of the traverse arm ceases. The traverse arm i3 is pivotally mounted by a pin 32 in a. bar

The traverse arm i3 is frictionaily held a socket M of the base i i and the lower end of the base is provided with a plate 35 that is secured to the base with screws Upon rethreading the winder the lever I8 is drawn downwardly and retained in this position with the yarn which extends through the eye 23 and over the surlace oi the cylinder ii to the core 2. 3.

The chain at is also connected to the yoke 19 in such a manner that as a cone or tube builds up in the yoke the upward movement of the outer ends of the arms and 2! also actuates the ratchet i5, and this movement of the ratchet also withdraws the ball 4i} from the socket @l thereby stopping the movement of the traverse arm H3.

The reciprocating movement of the traverse arm 13 is obtained by a lever is having a lot {39 therein and, as illustrated in Fig. 2, the lever All is pivotally mounted on a pin on the end of a support 5!. The support 5i is mounted in a slot 52 in a vertical channel shaped member 53 of the frame with a bolt 54 whereby the stroke is adjustable to correspond with the length of a cone or tube being formed. The upper end of the lever 38 is pivotally connected to the oar [5 with a pin 55 and a ball 55 on the lower end extends into a spiral groove 5? in the surface of a cylinder 58 and it will be noted that by moving the support 5% vertically the length of travel of the upper end of the lever 1% is adjusted.

The cylinder 58 is mounted on a shaft 59 and the shaft is rotated by a belt or chain 68 which is trained over pulleys 6i and 52. The pulley (it is mounted on the shaft i2 and a belt 63, which is also trained over the pulley 6| extends from a motor pulley (it on a shaft 55 of a motor 66.

A motor H6 drives a belt conveyor 81 with a belt 68 and pulleys 89 and i9 and, as illustrated in Fig. 2, the belt extends through a trough H whereby cones, tubes, cores, and other parts may be conveyed to and from the machine.

5 As illustrated in Figs. 5 and 6 the traverse levers !8 are formed with extended ends I2 that are positioned to be engaged by the yarn 23, as shown in Fig. 1, and the opposite ends of the levers are provided with offset sections I3 that enga the pawls H which operate the ratchet I6. From the offset sections I3 of the levers I8the levers are provided with sections 14 that extend from bases '35 through which the levers are pivotally mounted on a tranverse member I6 of the frame of the machine by pins TI. The pins I1 are positioned in fiat sections or bases 28 from which the'sections I5 extend.

The ratchets I6 are mounted on a shaft I8 and the pawls I l are mounted by eccentrics I3 on a shaft 80 which is journaled on transverse members 8| of the frame by bearings 82.

The pawls I! are resiliently held upwardly by springs 83 and similar springs 84 urge the levers I8 upwardly against the yarn.

The shaft 80 isalso provided with a pulley or sprocket 85 over which the chain or belt 53 is trained whereby the shaft 80 is rotated by the motor 66.

The traverse or grooved cylinders I I are formed, as illustrated in Fig. 4 with complementary sections and the sections are provided with hubs 05 on transversely disposed webs 3? and bolts 88 extend through the webs for securing the sections together. One of the hubs is provided with a key 89 by which the cylinders are keyed to the shaft I2.

As illustrated in Fig. 2 the cylinders are provided with pairs of grooves 21 and the grooves are positioned to correspond with the cones or tubes of different lengths, the pitch of the grooves being such that a groove extended from a point or vertex at the meeting point of sections of the groove leads yarn into a groove extended from a corresponding point at the opposite end of the cylinder. By this means the yarn is then fed continuously back and forth across a cone or tube as may be desired.

The yokes I9 in which the tubes or cones are held are provided with hubs 90 which are provided with radially disposed openings 9|, as

shown in dotted lines in Fig. 2, and the hubs are -mounted on studs 92 which extend from plates 93 that are provided with registering openings whereby the arms of the yoke may be set at different angles to correspond with the angle of a cone to be formed. The yokes are retained in adjusted positions by pins 94 that extend through the openings in the hubs and plates. The plates 03 are provided with extended arms 55 between which the sprockets 32 are positioned and the arms are pivotally mounted on a bar 96 of the frame by shafts 91 which are journaled in bearings 98.

The extended ends of the arms 20 and 2! of the yoke I are provided with cylindrical hubs 99 and I00, respectively and, as illustrated in Fig. 12, a frustro-conical shaped head I (H extended from the'hub I00 may be manually withdrawn by a disc I02 extended from the opposite end of the hub when it is desired to remove and replace a cone or tube.

A similar head I03 is journaled on the end of the hub 99 with a ball bearing I04 that is mounted in the head and positioned on a stud I extended from the end of the cylindrical hub. The head I 0| is also journaled on a shaft I 06 through a ball bearing I0'I that is mounted on a stud iiis'extended from the shaft. The opposite end of the shaft is provided with a section 409 of reduced diameter and the disc I02 is positioned on the end of the reduced section or stem 00. A spring H0 is positioned around the shaft and with one end of the spring seated against a stationary head III in the end of the hub and the other against a pin H2 extended through the shaft I05, the shaft is resiliently urged longitudinally with the head IBI extended into and in frictional contact with a collar IIZa having a set screw Ilse therein, in the large end of a cone. By this means cores of tubes or cones are removably mounted in the yoke It and cones or tubes formed on the cores may be removed as theyare completed and replaced with conical or frustro-conical shaped core members.

In the machine illustrated in Fig. 1, the parts are assembled to provide a unit on each side of the center and, as illustrated in Fig. 2, a plurality of units may be used on each side of the center. With theparts duplicated the reference numerals are applied to the unit on one side of the center only and it will be appreciated that the same reference numerals may be applied to corresponding parts on the opposite side of the center.

However, the belt or chain 03 extended from the motor to the cylinder carrying shaft I2 may extend over the sprocket 85 on the shaft or the cylinder carrying shaft M3 on one side of the machine may be driven by a chain or belt H4 from a pulley or sprocket on a motor I Hi.

The reciprocating bar I5 extends continuously through the unit of the machine and balls 40 of the traverse arms are freely positioned in sockets, similar to the sockets A! in the bar. The bar may be slidably mounted in bearings I IT in the frame.

One of the shafts i2 is positioned on each side of the machine and yokes, similar to the yokes I9 are positioned upon the common centrally positioned bar 05 whereby the yokes are free to swing vertically.

The yarn guiding grooves, as illustrated in Fig. 10, are oppositely positioned and are in the form of a V with the vertex or point of the V spaced from the ends of the cylinder and with the arms or sections at the sides positioned on equal angles from a plane extended through the longitudinal axis of the cylinder. The arms or sections of the grooves at the sides tapered out at points positioned between the vertices and the termination of quadrants in which the section of the grooves are positioned.

As an illustration the grooves of a cylinder if:

inches in diameter taper out at points positioned 4 inches from the vertex and also, as an illustration, the grooves are T33 of an inch wide by s of an inch deep at the vertex.

Furthermore, with the ten inch cylinder, as illustrated in the drawings, thirty-six inches of yarn is fed to the cone or tube with each revolution of the cylinder whereas in a conventional driving cylinder of three or three and onehalf inches in diameter about ten inches of yarn is fed to a cone or tube with each revolution, and should machines of this type be speeded up to wind thirty-six inches of yarn with the same comparatively small feeding cylinders, the traverse or yarn guide would travel so fast that it would be difficult to prevent breakage.

In using the large cylinder the amount of yarn supplied to the tubes and cones is increased without increasing the speed of the traverse or drive roll of the machine.

It will be understood, however, that these dimensions are only for the purpose of illustration and the grooves may be iforrned-ofajsuitable size in cross section and also of a suitable len th.

In the design illustrated in Figs. 15 and .16 a cylinder I29, similar to the cylinder l I is mounted on a shaft i2! that is journaled in bearings i22 and 23 in frame members l24 and [25, respectively and, as shown in Fig. 15, the cylinder is provided with grooves i26 and i2! that extend from points or vertexes M8 and E29, respectively at the points where the grooves are of greatest depth, to points I35 and BI, of the groove i238, and 32 and E33 of the groove I21, where the grooves taper out into the surface of the cylinder.

The yarn, as indicated by the numeral I34 is fed to the groove and cylinder through an eye 35 at the vertex of a triangle of a yarn guide 135 having converging arms that extend from a hub 13'? which is slidably mounted on a bar L38. The bar 233 is mounted in the frame members i2 3 and 525 and this bar and also a bar I39 provide guiding means for retaining the yarn guide 35 in an upright position. The member 35 is provided with a clip MB that extends around the bar 539, and the hub i3? is provided with a lug iti in which a follower N32 is carried. The follower M2 is provided with a boss I43 and a stud i i i which extends from the boss is positioned in an opening in the lug MI, in which it is held by a nut M5.

The follower M2 is positioned to travel in a traverse groove Hit of a cylinder hit which is mounted on a shaft M8. The shaft I43 is journaled in the frame members 524 and I25 and the shaft may be driven from the shaft 12! by a belt i 39 which is trained over pulleys I50 and 554. The shaft HE is driven by a belt 552 on a pulley 553, similar to the belt .53 and pulley 6|, of the type illustrated in Fig. 2.

In the design as illustrated in Figs. 2 and the pairs of grooves at the ends of the cylinder are positioned for winding a 10 inch cone or tube, the next pair of grooves for winding an 8 inch cone or tube, and the grooves at the center for winding a 6 inch cone or tube. It will be understood, therefore, that the grooves may be positioned at different distances on the cylinder whereby cones or tubes of different lengths may be formed.

With the cylinder and traverse combination as illustrated in Figs. and. 16 the cylinder is provided with one V-shaped groove at each end and the grooves are oppositely positioned so that the yarn is carried to the end of the cone or tube and started back with the grooves.

It will also be noted that the grooves of the traverse cylinder M? are positioned to start the yarn guide in the reverse direction with a comparatively easy movement, the meeting ends of the grooves being provided with straight sections i5 5 and 55 and the cylinder being provided with blocks E56 and 957 that are positioned to be engaged by the follower.

With the grooves formed in this manner the pitch of a groove at one end is such that in making one revolution the groove leads into a corresponding groove at the opposite end of the cylinder H. Furthermore, with the grooves formed in this manner the grooves lead the yarn to the end of the cone or tube and bring it back thereby forming tapered ends and at the same ime, in holding the yarn in tension the ends of cones or tubes formed on the machine are tight or firm.

It will be understood that modifications may be made in the design and arrangement'of the parts without departing from the spirit of the invention.
