wnvnnve MACHINE.

Application filed April 17, 1925. Serial No. 23,760.

This invention relates to winding machines and traverse mechanism therefor, and more particularly to machines adapted for winding strands of textile material.

In order to utilize suitable fibres for preparation of yarns or the like for use in Weaving, knitting, and other kinds of manufacture, it is necessary to subject the fibres to a series of operations to form slivers, rovings, yarns and the like. For example, in the manufacture of cotton yarn, such steps are, starting with cotton in the bale; (1) opening and picking; (2) carding and combing; (3) drawing; (4) roving and (5) spinning. After the baled cotton has been separated and cleaned to some extent in the first opera tion, it is subject-ed to the carding, operation in which the fibres are straightened, formed into a thin, evenly divided film, passed by calender rollers through a trumpet in a round strip called a sliver, and the sliver is automatically coiled in a sliver. can by a coiler. Y

In different steps of the process, the mass of cotton is doubled,,that is, a plurality of strands are combined, and then is reduced in size by drawing it out to several times its original length until the yarn is really produced. This operation tends to straighten the fibres and bring them into nearly parallel positions. In the drawing operation, several slivers are comb1ned, drawn out, pulled through a trumpet, and coiled in a can, th s operation being repeated as many times as required.

The cans of sliver are then placed behind the first of theroving machineswhich, be-

sides rolls similartothe f drawing frames,

have spindles by which the stock, then called roving, is twisted and Wound on bobbins. The full bobbins of. roving from the first frame or slubber are placed in the creel of the intermediate frame, certain strands are combined, drawn and. substantially in one operation twisted. andwound on a bobbin. similar operation is carried on in the frame. Further twisting of the rovings isefiected in the spinning operation.

An important ob'ect'of the present invention is to provide novel and improved mechanism for readily and efficiently Winding or reuniting the yarn prepared from the revmgs as above specified.

A. further object is to provide noveland thereon strands 4.-

maintaining the yarn rolls taut and for facilitating uniformity in the Winding and relating to details of construction will appear from consideration of the following ,detailed description and of the accompanying drawing in which Figure 1 is a view in elevation of an approved embodiment of the invention;

Figure 2 is a sectional view taken along the line 2-2 of Figure 1; and

Figure 3 is a view of another form of means for traversing the yarn guide.

For convenience, the term strand will be used throughout the specification to include rovings, yarns or strands formed at other stages in the manufacture of spun yarns.

In the illustrated embodiment of the invention, provision is made of a plurality of pairs of rollers, one pair above another, to

support and drive tubes on which the strands are to be wound, the tubes beingheld against the driving rollers of each pair by rollers of substantial weight which also serve to compress the material wound on the tubes. The

strands are presented to the tubes of each set I the machine. Projecting transversely from this leveris an arm adjustablyconnected witlrthe lowerend of a llnk whose upper A' end is pivoted to a vertically reciprocable slide actuated by a heart cam.

It should be understood that the traverse mechanism herein disclosed is adapted for use in actuating more than two of such longitudinally movable rails.

' As herein disclosed, the machine comprises upperand lower pairs of rollers 1 and 2, respectively, to turn tubes 3 and wind of the material to be mamas handled. The rollers 1 and 2 are journallediin end frames 5 andfi connected, for example, by spacing tubes 7 and rods 8 passing through said tubes 7 and having threaded en'ds to-receive suitable nuts.

Above each pair of rollers 1 and 2 is a presser roll 9 of substantial weight mounted on a shaft 10 which is slidably mounted at its ends in the end frames. Such rolls 9 are lifted when the tubes are to be placed on the pairs of winding rollers and also when the tubes are to beremoved, and during the winding operation serve to hold the '12 and of gears 13 mounted on the shafts of the rollers 2 and meshing with a gear 14. The gear 12 is fixed to a sprocket wheel. 15 which is connected by a chain 16 with a sprocket wheel 17 of the same size as wheel 15 and on a shaft 18 which also carries the gear 14 and turns the same. The shaft18, which may be considered the main shaft of the machine, is journalled in the end frames 5 and 6 and may be driven by toguide the strands to the tubes 3 so that the packages of strands 4 will be built up in the proper manner. To this end, provision is made of a plurality of guide members 21 in the form of grooved rollers mounted on a rod 22 carried by arms 23 fixedv on a shaft or rail 24 slidably mounted on the end frames 5. As indicated in Fig. 2, the guide members 21 of the two sets may rest on the adjacent winding rollers 1 and 2, respectively.

To reciprocate therails 24, the upper one thereof is connected by a link 25 to one arm of a lever 26 centrally mounted on a pivot 27 and the lower rail 24 is connected by a link 28 with the other end of lever 26. For driving purposes, the lever 26 isprovided with an arm 29 perpendicular to the main portion of the lever and provided with a series of openings 30 to receive a pivot to connect the same with one end of a link 31 connectedat the, other end with a member or bar '32. reciprocable in aiguide 33. It will beevident that by changingthe connection between the arm 29 and the link 31 the extent of movement of the guide members 21 may be varied without varying the movement of the reciprocable member 32.

To reciprocate the member 32, use is made of a shaft34 journalled .in the end frames 5 and passing through the slotted lower end of the member 32 to assist in guiding the same. Fixed on the shaft 34 is a heart cam 35 which engages cam followers or rollers 36 on the member 32 and actuates the latter. Actuation of the shaft 34 may be effected by means of a gear'37 on'the right'hand end (Figure 1) oft-he shaft of the front roller 2, a gear 38 on the right hand end of shaft 34 and an idler gear 39 meshing with both of said gears 37 and 38. It should'be understood that provision may be made for using gears of other sizes instead of gears 37 and 38 and of a suitable idler gear to cooperate therewith. As shown in Figure 2, there is a bracket 40, in which the idlergear 39 issupported, and an unused bracket '41 which might be used to support an idler cooperating with gears substituted for 37 and 38.

As shown most clearly in Figure 2, the link'31 is connected with the reciprocable member 32 by a member 42 and to assist in securing proper action of the parts, the member 42 is provided with an upwardly extending bar 43 slidablc in guide 33.

According to a modified form of the invention, the connection between the heart cam 35 and the lever 26 may be effected by means of member 44 actuable by the heart cam in the same manner a-s'bar 32-but connected directly with the arm 29 by a pin and slot connection 45.

It will be seen that the traverse mechanism is so arranged that uniformity of winding on all of the tubes will be obtained-and that the number of winding devices placed one above another may be increased as desired.

lVhile I have disclosed herein preferred means for carrying out my invention, 1 wish it to be understood that 'I do not limit myself to the structure herein disclosed and that various modifications and variations may be used without departingfromthe spirit of my invention.
