Patented Dec. 10, 1940' PATENT OFFICE WINDING MACHINE Edward J. Abbott, Wilton, N. 11., assignor to Abbott Machine Company, Wilton, N. IL, a corporation of New Hampshire Application February 25, 1935, Serial No. 8,013

6 Claims. (Cl. 242-355) This invention relates to traveling spindle winders, and is of particular applicability to traveling spindle winders for producing headless cross-wound packages of yarn and the like. In

the past, winding machines of this typehave involved the use of traverse elements which are moved to and fro in proximity to the winding package for laying the yarn into the desired quickpitch spiral formation on the packages during travel ofthe packages around the machine.

Thus my Patent No. 1,609,639 discloses the inclusion on the traveling winding unit, of a vertical oscillating arm of which the upper end is adapted to serve as a guide eye for the yarn near the face of the winding package. The Reissue Patent No. 18310 to Edward J. Abbott and William J. Abbott, Jr., discloses the provision on the traveling unit of a reciprocating slider carrying a guide eye for traversing the yarn.

For certain types of yarn and certain conditions of winding it is advantageous to employ traversing means of a type which does not involve the use of reciprocating or oscillating parts. In cases where the yarn can be laid sufiiciently 25 exactly to satisfy the demands of the industry without the use of a reciprocating or oscillating guide eye, the elimination of such element and its operating mechanism is advantageous in reducing noise, preventing certain friction losses, and simplifying the lubrication of the units;

The principal object of this invention is therefore to provide for incorporating in the flexibly connected units of a traveling spindle winding machine traverse devices adapted to distribute 35 the yarn in quick traverse cross-wound formation without the use of a reciprocating or oscillating yarn guiding eye, and to provide for operating such traverse mechanism while the units travel around the guideway of the machine. 40 Other objects of invention and features of advantage relate to details of the winding unit, some of which are of general application.

In the drawing:

Fig. 1 is a front elevation of a traveling wind- 45 ing unit of the present invention, showing a part oi the track or guideway for the several units of the machine; I

Fig. 2 is a left elevation of the device of Fig. 1, showing the track or guideway of the machine in 50 vertical section; and a Fig. 3 is a view of the rotary yarn cam of the unit, half in elevation and half in longitudinal section.

The several fiexibly'connected winding units 55 of the machine are adapted to be conveyed in. a

closed path having straight and semi-circular portions in the mannerand by the means described in the above patents and in my co-pending applications Serial Nos. 476,776, now Patent No. 2,135,485 and 677,749, now Patent No. 1,993,910. 5

Each unit consists, as shown'in the drawing, of a vertical frame piece ll provided with a roll 12 and pin 13 to guide its lower end on the lower rail Id of the guideway, andprovided at its upper end with a cast head piece 15 having integral 10 opposite vertical side portions [6 and ii and also carrying rollers l8, l9 and which guide the upper part of the unit on the upper rail 2| of the guideway. The unit is shown as flexibly connected to a conveying chain 22 such as described 15 in the above patents and applications.

The spindle 25 for holding the winding package core '26 is mounted in an arm 27 which is pivoted at 28 on an upward extension l6 of the side portion it of thehead of the unit. A wire bail 30, Q normally pressed away from the observer in Fig.

1, by the running yarn, is adapted to control suitable winding stopping mechanism, including the package lifting rod it, in the manner described in the above applications, the stopping mecha- 25 nism also preferably being adapted to lift and lower. the package at predetermined places in its path of travel as fully described in the above applications.

Between the upright vertical side portions it 30 and ii there is mounted a rotary yarn traversing element 36 adapted to serve as a friction drive roll for the package formed on the core 26. This traversing and driving element may, for example, take the form of a drum having in its surface a yarn traversing groove 35 which may be shaped according to any of the patterns disclosed in the patents to Colman, No. 1,175,710, Colman, No. 1,274,386, Reece, No. 1,749,355, Bood, No. 1,836,105 or McKean, No. 1,918,210.

As shown in Fig. 1, the winding package core 29 initially rests on this grooved drum, so as to be driven thereby. Yarn coming from a bobbin 39, through guide wires i0 and over the bail wire 30,,is then distributed on the core 28 in crosswound spirals by the grooved drum M.

The driving means for the drum 34 is preferably in the form of an electric motor, which as indicated in Fig. 3, includes a stationary field 4| on the shaft 62 which is held by the side member it of the unit, and a rotary armature 43 fastened to the inner surface of the rotary drum 34. Current is supplied to the stationary field 4| by wires 45 from a group of brushes 46 which slide vided with an operating handle 49 adapted to'be actuated by a projection 50 from the pivoted arm 21, so that when the arm 21 is raised to the height corresponding to the completion of a fully wound package the switch 48 is opened and the motor and drum 34 stopped. This action likewise takes place when the arm 21 is raised by the action of the lifter rod 3|, for example when the latter is raised by actuation of the bail wire and the associated stop mechanism of my aforesaidapplications.

In operation, the several units are conveyed in a procession around the machine. Upon reachingthe place at which replenishment operations are conducted, the stopping mechanism of each unit is successively operated by actuation of the lifter rod 3| of the unit,- and upon passing the place of replenishment the winding package of the unit is automatically placed in contact with its drive drum 34 U and the motor started by means of the rod 3], arm 21 and switch 48, and the lifter rod actuating mechanism or application Serial No. 476,776. I It will bev observed that the present inventio j renders it possible to wind cross-wound packages on the flexibly connected units of traveling spindle winders without resort to the usual reciprocating or oscillating traverse guide eyes. It moreover provides forcontrolling the several driving and traversing drums individually, so that the individual units are stopped successively for replenishment without stopping the remaining active units, and the drive drums are severally stopped upon the breakage or exhaustion of the strand without stopping the drive'drums of the other units.

I claim;

A multiple traveling unit winding machine havingtherein a plurality of flexibly connected winding units each including a grooved rotary package driving element adapted to distribute the winding strand on a package, the machine including means for moving the units in a procession around the machine and means for driving the several said rotary elements during travel of the units.
