SLIVER-HANDLING DEVICE.

Application filed February 6, 1922. Serial No. 534,445.

To all whom it may concern:

Be 1t known that 1, JOHN W. GURLEY, a citizen of the United btates, residing at Indianapolis, in the county of Marion and State of Indiana, have invented a new and useful Sliver-Handling Device, of which the following is a specification.

In the manufacture of twine, the sisal or manila is first made into a sliver on a spreader and then drawn into successively liner slivers by being passed successively through other Spreaders, draw frames, and finishers until a sliver of the desired fineness is obtained. Heretofore the sliver as it came from each of these machines has ordinarily been coiled by hand in a can, the coiling of the sliver in the can requiring con siderable skill; and the cans with the coiled sliver within them have been carried from one machine to another, and used as fee cl cans over the edge of which the sliver was drawn when fed into the next succeeding machine. This scheme has not only required a great deal of skilled labor, but has been disadvantageous also because of the diiiiculty of getting the sliver out of the can either for feeding or for other reasons, and because of the cutting or tearing of the sliver as it passed over the edge ot'the can.

It is the object of my present invention to coil the sliver automatically in a can, thus eliminating the necessity for the skilled labor heretofore required for coiling it; and to coil it in such a way in the can, and to make the can of such construction, that the coiled sliver may be removed laterally from the can and dragged independently of the can from one machine to another; so that the number of cans is reduced, one can to a machine being sufficient, and the difliculties involved in removing the sliver from the can are overcome. a

The accompanying drawings illustrate my invention: Fig. 1 is a perspective view of a can and sliver-feeding mechanism embodying my invention, in connection with a draw-frame which is shown in dotted lines; Fig. 2 is a plan of the can and sliver-feeding mechanism which feeds sliver thereinto,

with a fragment of the associated draw frame; Fig. 3 is a side elevation, in partial section, of the swinging feed chute; Fig. 4 is a section on the line 1-4 of Fig. 2; Fig. 5 is a section on the line 55 of Fig. 2; Fig. 6 is a Vertical section of the pivotal mounting on the sliver-receiving can; and Fig; 7

IS a plan of the can proper, showing the can open in full lines and closed in dotted lines. The draw frame 9 shown in dotted lines 111 Fig. 1 may be of any suitable construction, and is merely representative of the vallOIlS sliver-treating machines, such as Spreaders, draw frames, and finishers, with any of which my invention may be associ ated. From any of these machines, which takes the sliver and draws and works it into a finer sliver in a well-understood man ner, such finer sliver 10 is discharged at the end of the machine, the sliver as it-is discharged passing between two grooved delivery rollers 11 and 12 with which such machines are usually provided and which assist in drawing the sliver through the machine. These delivery rollers lland 12 are driven in any convenient manner by drive 'mechanism forming part of the sliver-treating machine, the roller 11 being shown as mounted on a shaft 13 which is assumed to be so driven.

The sliver 10 is discharged into a can 15, embodying my invention, which can 15 takes the place of the cans heretofore used for receiving such sliver. This can is mounted on a turn-table base 16 suitably mounted for rotation, as by having a pivot stud 17 mounted in a bearing socket 18 set in the floor 19, as is clear from Fig. 6. The sides of the can are made of two

cylindrical segments

20 and 21, which project upward from the edge of the base 16. The segment 20 is fixed on the base 16, in any suitable way, and the segment 21 is mounted on the segment 20 on'vertical hinges 22 so that it may be swung to closed position as shown in Fig. 1 and in dotted lines in Fig. 7, to form a complete cylindrical can, or to open position as shown in full lines in Fig. 7 to open the side of the can for half its circumference. The opposite edges of the

seg ments

20 and 21 from those which are hinged together by the hinges 22 are preterably arranged to overlap, as indicated in Figs. 1 and 7, and are provided with any suitable cooperating latch parts 23 for holding the segments in closed position. When the segment 21 is in closed position, the sliver 10 maybe coiled within the can; but when the. segment 21 is swung open, the coiled sliver within the can may easily be slid out laterally onto the floor 19 and dragged to any desired'place without moving the can. 7

, in a closed path.

The basel 6 and can 15 are driven in synchronis'm with the draw frame9 or other-associated sliver-treating machine. Such driving is conveniently obtained by a belt which runs in a groov in the periphery of the base 16 and passes over 'id'ler pulleys 26 to a driving pulley 2-Ton any convenient moving shaft 28 of the draw frame 9. The

pulley 2'? is shown as on the sprocket shaft 28 of one of the drawing chains, though any other shaft may be used.

llhe sliver 10 is fed into the can by my automatic feeding device. This is fundamentally a swinging chute 30, which is shaped much like a cupped human hand, and which is mounted to swing from side to side and up and down in synchronism with the draw fran'i 9. To this end. the swinging chute 30 is made of curved cross-section, to evtend about half way around the sliver on its upper side. and is also curved longi tudinally to direct the sliver downward, clear from Fig. 3. its rear end the chute 30 is mounted by an upwardly projecting countersunl: pivot bolt 31 to the lower end of a swivel cup 32 having a transverse hole 38 through it for receiving the horizontal finger 3% f a standard 35 suitably mounted in a cross bar 36 at the discharge end of the draw frame 9. th swivel cup 32 being held from longitudinal movenzent along the linger 3% in any suitable way, as by lying between a pair of cross-pins 3i projecting through such linger (Fig. 2). This makes a universal mounting for the rear end of the swinging chute 30 so that it can swing up and down around the axis of the finger 34 and can swing laterally around the axis of the pin-31.

Any suitable means may he provided for giving the chute 30 this double swinging n'ioveinent. so that its free end will travel is shown, the chute 30 is provided on its upper surface at its free end with upwardly projecting eye l0, through which loosely prcjeits a pin 41 on one end of an arm 42. Said arm near its other end projects slidir I v through a swivel member 43 transversel. to the axis thereof, and such swivel member 43 is swivtled on the u; oer end of a rod l which is vertically adjustable to vary the l? at o the swivel member The, vertical. adjustircnt the rod 4% is convenicntl" obtained by having it project through Jined holes in the legs of a suitably suppo; ted L -shaped member so that a spring-pressed shoe 46 on the end of a pin l? project" thr'o h the base the Ushaped mem: e1 will bear aga nst the side of the rod 44; hctwccirthe two ho es. through which it pa. and friction: ll hold it'in ad of-the rod 1 .i. in Fig. 1, to provide an adjust ng handle. This provide? a vertically adjustable fulcrum point in which the arm 42 both swings extending linger 58, provided with a hole through which projects an eccentric pin 49 carried by a disk 50 on a shaft 51 suitably mounted in a bearing support 52 mounted on the cross bar 36. 'At its other end the shaft 51 carries a friction disk 53 with the face of which a friction roller 54'011 the shaft 13 cooperates. The roller '54 is preferably adjustable axially of the shatters, as indicated in Fig. 2,'by such adjustment producing difi erent relative speeds of rotation of the

shafts

13 and 51.

In operation: The rollers 11 and 12 dis charge the sliver 1O beneath the swinging chute 36, which directs the sliver downward into the can 15. The chute 3O swings both on the axis of the finger 34 and on the aXis ot the pivot bolt 31., so that its free end travels in a closed path to direct the sliver 10 into the can 15 in the form of a coil. This movement of the swingingchute 30 is produced by the action of the eccentric pin 49, the rotation of which both sw'ingsthe arm 42 up and down with the swivel member 43 as a fulcrum and slides such arm 42 longitudinally back and forth in the swivel member 48. The swinging movement of the chute 30 is of such extent that it makes a sliver-coil of less diameter-than the can '15, preferably about half such diameter, as is clear from Fig. 2. At the same time that the sliver is fed into the'can 15, the can is slowly rotated, so thatzt'or each turn or coil of the sliver the can makes a fraction of a revolution; so that as a result successive turns or coils of. the sliver are not directly superposed, but instead are displaced circumferentially of the can. This makes a non-tangling coil. When the can 15 is full, the side segment 21 thereof may be swung open and the sliver-coil within the can may be dragged out of the can onto thefloor 19, or onto a low truck, and slid on the floor or carried on the truck to the next machine or other desired place. Then the side segment 21 is closed again.. and another coil or sliver 10 is fed into the same can.
