AMERICAN BEMBERG CORPORATION, OF NEW YORK, N. Y.,
DELAWARE OFJOHNSON CITY, TENNESSEE, ASSIGNORS TO A CORPORATION OF TWISTI'NG AND WINDING MACHINE Application filed April 2,
This invention concerns the handling of textile yarns and has particular reference to the provision of an improved apparatusfor twisting and winding textile yarns such as silk or artificial silk yarns.
In order to facilitate the handling of such yarns, it has become the practice to wind the yarn upon large shipping bobbins containing from to 2 pounds or more of yarn per pack'ag In order to wind these large bobbins, which may be bottle bobbins, cones, tubes, warping bobbins, etc., it has been customary to deliver the yarn from the twisting spool to a delivery spool or bobbin from which it is necessary to rewind the yarn upon the shipping bobbin in a separate operation and upon a separate machine.
It is an object of our invention to provide an apparatus with which the yarn ma be wound directly upon a shipping bobbin from a twisting bobbin, without the intermediate step of winding upon a delivery bobbin. It is a further object of the inventionto avoid zontal pulley the intermediate winding step avoid the additional handling of the yarn, which is detrimental to the yarn, and which greatly increases the labor and equipment costs. Other objects will become apparent. In describing our apparatus and method, reference will .be made to the drawings in which Fig. 1 is a front elevation of one end of a row of machines embodying the invention and Fig. 2 is a view of machine shown in Fig. 1.
Of the numerals designating like parts upon the several figures, 11 denotes a twistto an uptwister or upspinner system. This bobbin is rotated at a constant speed by a belt 12 driven by a hori- 13 fixed to a verticalshaft 14. The moving belt 12. contacts with the pulley 15 and rotates the bobbin in the desired direcand to thereby one end of the means ofthe spring 19.
1930. Serial No. 440,909.
the uniform yarn speed type, in which the bottle bobbin 21 is rotated by a spindle 22 driven by a friction contact between the disk 23 and the pulley 24 fixed to the shaft 25.
The thread guide 26 is carried upon a threaded vertical shaft 27 fixed to the horizontal bar 28, which is reciprocated vertically by means of the shafts 29 actuatedby the cam 30. As the shaft 29 reciprocates vertically, the shaft 25 is reciprocated longitudinally by means ofa pivoted lever 31 actuated by the movement of the shaft 29. The relative movements of the shafts 25 and 29 are such that the pulley 24 moves toward the outer edge of the disk 23 as the guide 26 is lowered. Since the pulley 24 is rotated at a constant speed, the speed of rotation of the bobbin 21 will be varied and the relation between the variation in the speed and the variation in the diameter of the conical portion of the bobbin is such that the circumferential speed of that portion of the conical surface of the bobbin that is opposite the guide 26, is always maintained constant. The individual winding bobbins may be stopped by rotating the lever 32, which lifts the disk 23 from the pulley 24.
In order that the two bobbins may be started and stopped together, the rod 33 may be connected to the pivoted arm 17 so that a rotation of this rod 33 will rotate the arm 17 about the pivot 18. Therod 33 in turn is connected to the collar to which the handle 32 is connected through two levers 34 and 35 and a link 36, so'that a movement of the handle 32 will rotate this rod 33 and swing the pulley 15 into or out of contact with the belt 12. The yarn 37 from the 'bobbin 11 is led through theeye 38, around and through the friction eye 39; through the guide 40, around the guide wheel 41, supported upon the spring 42, and around the guide pulley 26 to the bobbin 21.
The shaft 14 may be driven by the motor 43 and the shaft 25 may be driven by a belt 44 from the shaft 45, which, in turn, is driven by the shaft lei-through the worm drive 45a. The shaft 46 is rotated, through gears 47 and 48,'by the shaft 25, the gear 48 and the pulleys for the belts 44 being loosely keyed to the shaft 25, so that the latter may slide through the gear and pulleys as it is reciprocated by the lever 31. y
In operating our combined twisting and winding machine. the filled bobbin 11, wound with yarn made up of substantially parallel strands, is placed upon the spindle 16 and the machine is threaded as shown in the drawings. An empty bott e bobbin is placed upon the spindle 22 and the yarn is secured around it. The pulley 24 and the belt 12 are put into motion at such relative speeds that the desired number of twists, for example 2% or 5 twists per inch, may be made as the yarn is drawn from the bobbin 11 and wound upon the bottle bobbin 21 at a uniform lineal speed.
By using the actuating means 33, 34, 35 and 36, the two bobbins may be put into operation simultaneously, or if it is desired to start the twister first, sufficient play may be left in the mechanism for lowering the disk 23 so that it will lag behind the actuation of the twister. In this way the yarn may be given an initial twist before the winding operation is started in order to give the required amount of twist to the portion of yarn between the two bobbins.
The rotation of the twisting bobbin 11 will cause the yarn to balloon between the bobbin 11 and the eye 38. The centrifugal force of this balloon is such that it will compensate for any slight inaccuracies in the lineal speed of the yarn drawn by the bobbin 21 and will produce a constant tension upon the yarn drawn from the bobbin 11 and therefore a constant lineal movement of this yarn. The friction eye 39 and the spring 42 will further compensate for any variations in tension resulting from slight variations in the speed of the yarn drawn by'the rotation of the bobbin 21.
By this means a yarn of constant twist may be continuously drawn from the uptwister and wound directly upon the bottle bobbin, without the necessity of winding and rewinding upon a delivery spool or bobbin.
As the bobbin 21 fills up, the yarn wound upon it contacts with the wheel 43a and rotates this wheel upon the screw threads of the shaft 27 to gradually increase the height of the guide 26. Additional bobbins similar to 11 may be substituted when each one is emptied, to completely fill the bobbin 21.
- Although we have described our invention as applied to an uptwister and a bottle winding bobbin, it is apparent that it may be applied to other types of twisters, and to other types of winding bobbins, such as cone bobbins, tubes, cops, warping spools, etc. It is not intended to hereby limit our invention to the particular embodiment shown since the novel principles involved may be utilizel in many other modifications.
The actuating means for rotating and reciprocating the moving parts of the mechanism, described are merely illustrative of standard means for accomplishing the desired relative movements and it is apparent that many other arrangements for accomplishing these results may be utilized. Although we have described only a single embodiment of our invention, it is apparent that many other applications of it may be made.
What we claim is:
1. In an apparatus for twisting and winding yarn, the combination wit-h an uptwister, of a bottle bobbin rotated at varying speeds to maintain a constant yarn speed and means between said twister and bottle bobbin for compensating for variations in tension upon the yarn as it is drawn from the twister.
2. In an apparatus for twisting and Winding yarn, the combination with an uptwister, of a bottle bobbin adapted to draw the thread from the uptwister at a constant yarn speed, separate friction drives for said uptwister, and bottle bobbin, and means for engaging and disengaging both of said friction drives by the movement of a single lever.
3. An apparatus for twisting and winding yarn comprising an uptwister, a winding bobbin of uneven diameter and a resiliently supported guide for taking up slack in the thread between said uptwister and the winding bobbin.
4. An apparatus for twisting and winding yarn, comprising an uptwister, a Winding bobbin of uneven diameter driven at changing angular speeds to give the yarn wound upon it a substantially constant yarn speed, a friction guide and a resiliently supported guide wheel for taking up slack in the thread between the uptwister and the winding pulley.
In testimony whereof, we have signed our names to this specification this 27 day of March, 1930.
