Fig. 8 is-a diagrammatic plan view illustrating one desirablearrangement of driving 7 p connections; and v V Fig; Q is airagmentarysection on the line 99=oi F ig.-2;j

Referring to Fig. 8 there are illustrated, in diagrammatic plan view, certain driving connections of a kind commonly employed in gill box mechanism of usual type, together with certain adjunctive features pertaining parti cularly to the present improvements. Thus in Fig. 8 the numeral 1 designates a main drive shaft adapted to receive power from any suitable source and which through proper gearing transmits motion to the back shaft 2 and to the shaft change gears 3. The back drawing rolls are shown at 4, the front drawing rolls at 5, and the gill box fallers at 6, the latter being actuated in any usual manner by means not herein specifically disclosed.

Referring to Fig. 2 the machine frame supports a bracket 7 carrying a vertical board 8 having porcelain pot-eyes 9 suitably arranged to receive and to guide strands S which may be supplied from any suitable source. For convenience in description, but without intent to limit the scope of the invention, these strands S may be considered as slivers of wool or other desired material, which has not yet received any substantial twist or been subjected to a spinning operation. These strands or slivers S, after pass.- ing through the pot-eyes 9, are preferably caused to pass over the upper surface of a supporting table 10, the several slivers being arranged in closely adjacent parallel relation. In the present apparatus these slivers may be divided into two groups as indicated, for exampleat S S (Fig. 3) but any other suitable grouping of the slivers may be employed. in. accordance with the general arrangement and intended mode of operation of the machine. These groups of slivers next pass through the back draft rolls 4 and, after engagement by the fallers 6 of the gill box, are delivered to the front draft rolls 5. The driving gearing for the draft rolls and fallers may for example be such that the surface speed of the front rolls 5 is approximately six times that of the rear rolls 4, so that the sliver is drawn out and its fibers brought into approximately parallel relation. The fallers 6 preferably have a linear speed slightly greater than that of the rear'rolls 4 and the fallers thus assist in laying the fibers in parallel relation. Preferably the front upper roll 51s provided with one or more endless aprons 11 extending around a roll or rolls on an idle shaft .12, such an apron or aprons assisting the front roll in securing a proper traction upon the sliver;

In the present arrangement the machine frame supports a pair of brackets 13 (Fig. 2) which in turn carry bearings 14 providing trunnions for a pair of guide trumpets 15. Each of these trumpets is designed to receive one of the groups S or S of slivers and to deliver the slivers of such group to the winding devices as hereinafter more fully described. If but a single groupof strands .be

used, a single guide trumpet will suifice, and on the other hand if a greater number of groups of slivers be used, a correspondingly increased number of trumpets will be employed. Each guide trumpet 15 is provided (Fig. 9) with a longitudinalpassage 16 for the strand and such passage is preferably of small diameter, at its delivery end at least, so as to compress and firmly compact the constituent fibers 0f the strand as the strand is delivered to the spool. While it is not necessary to use a trumpet which oscillates or makes a part turn alternately in opposite directions, I prefer to oscillate'it, since the turning of the "trumpet tends to smooth and round the sliver and to assist in compacting it. To oscillate the trumpet, it is furnished with a pulley 18 about which is wrapped one runof an endless cord 19, which also passes around pulleys 20 (Fig. 3) mounted upon a reciprocating carriage, hereinafter described. For best results, the delivery end ofthe trumpet guide is arranged close to the nip of the winding elements, preferably at a distance therefrom less than the length of the normal vfiber of the strand being wound. With this arrangement, the strand may be wound under a tension which would break or at least weaken such untwisted material if wound according to usual methods.

A substantially horizontal rotary shaft 21.

(Figs. 1 and 3) is mounted at its opposite ends in bearingssupported by brackets 22 and 23 respectively extending laterally from opposite sides of the main frame of the machine. This shaft carries a driving drum or roll 24 preferably having a roughened or corrugated surface and which is movable axlally of the shaft 21 but is constrained to turn with the shaft by means of a suitable spline connection. At the right-hand side of the machine, as viewed in Fig. 1, the shaft 21 carries a gear 26 which is housed within a gear box 25 supported by the bracket 23. This gear 26 meshes with a change gear 27 carried by an adjustable bracket, and the gear 27 meshes with a gear 28 secured to the end of the shaft 5 which carries the bottom roll 5.

A fixed guide bar 29 parallel to the shaft 21 is secured at its opposite ends in the brackets 22 and 23, and this bar and the shaft 21 form supports for the reciprocating carriage 30. This carriage is provided with end frame members 31 and 32 (Fig. 1) having hollow bosses 33 and 34 respectively for the passage of the shaft '21. These bosses at their inner ends engage the ends of the roll or drum 24 forming abutments for the latter which constrain the roll or drum to partake of the longitudinal reciprocating movement of the carriage.

Referring to Fig.2, the lower member of the carriage is provided with a rack bar 85 which meshes with a pinion 3 6 secured to the upper end of a vertical shaft 37 mounted memes V :bearings 38'- and 39: 'ada-pted to. permit a slight oscillatory movement of the shaft. A'

V mangle gear .40 is secured 'to the :lower' .end

' of theishaft'37, andsthis gearis'provided with a. series of pins P (Fig. 6;) engaging a toothed pinion 41 securedto the lower end of a shaft 42- ournaled .in suitable bearings car niedby the-machine frame. A beveled gear 43 '(Fig. 1) is secured to'the upper end; of theshaft 42 andmeshes-with.agear-ll on a horizontal shaft 45 which extends into .the

gear box 25.where itcarries apinion 46;

This pinion meshes with a change gear 47 (:Fig. 4) mounted uponan ustable bracket and thisgear 47 mesheswith the gear 26.

Referring toF igs. 1 and 5, the end members 31 and 32 of the carriage are furnished idler! pulleys 54- and which are. secured respectively'to the opposite ends of a tension spring 55. This spring, acting through the connections.described, tends to: swing the arms downwardly in a counterclockwise direction: as viewed in Fig. 5,-itbeing noted that by the use of 'a single spring a substan- 'tially equal force will always be applied to the two arms. It is also tobe noted that the relative arrangement of the pin 50 and the fulcrum or pivot 49 is suchthat whenthe arm swings upwardly, the force of the spring 1s applied-with a decreasing moment'arm or leverage.

Each of the arms 50is provided with a boss58for the reception of a. trunnion device which, in its preferred form, comprises a short shaft 59 arrangedato slide axially and also to rotatein a bore in the boss 58. This shaft carries a head member 60, preferably in theform of a disk of substantial diameter,

mounted upon the shaft 59 with interposed anti-friction bearings 61, so that the head may turn: freelywith reference tothe shaft 59.. Preferably thisdisk 60 is furnished,near; its outer edge,--withan annular axially ex-i tending flange 62, and with a radial marginal flange68. The shaft 59 is provided withan actuating. arm or handle 64 which projects out. through a cam slot 65v in the bearing 58,

the slot comprising a portion which lies in a plane substantially perpendicular to the axis.

of the shaft so that when the handle 64: is disposed inthis part of the slot the'shaft 59 is held. against axial: movement;

The trunnion devices are-adapted to support between them a large. spool',.for example a dresserspool, having afhollow rigidlbarrel 66, which may, if desired, be of perforated metal, and having heads 6'1 fixedly secured to each endof the barrel. The machine is designed to accommodate spools having heads at least-as largeas thediameter of the'completed textile ma-ssf The heads :60 of 'ther trunnion devices are of a diameter "to permit the'flanges-GQ to fit snugly wvithin the' hollow" barrel-,withthe flanges 68 engaging the outer ends of the spool. Sincethe method of winding here employed results in the formation of a dense self-sustaining package, the spool may have arigid barrel of fixed -length with its heads fixedin position, it being. unneces-' sary to compress the package axially during pressure. dyeing. In the operationof the machine the slivers or strands S coming from any suitable source scribedpthr ough the back and, front draft pass through thegpoteyes 9, as above 'de- 7 rolls, and across the fallersifi so that the fibers forming the strand emergefrom the front rolls 5 in substantially 'parallelrelati'on.

The groups of sliversnow pass through the respective trumpet guldes ,and the carriage.

30 being in motion, the cord'19 causes these guides to oscillate on their own axes, thus rounding and's'moothing the sliver passing through them. The reciprocating motion of the carriage causes the'drum Q lto reciprocate relative to the guides and, it. being assumed that a spool has been mounted upon, the

trunnions, the spool also participatesrinnthis reciprocating movement.

The ends-of the strands delivered from the trumpet guides are secured to the spool barrel in any usual way, and as the drum 24' revolves itcauses the. spool also 'to revolve, the spool barrel resting withsubstantial pressure 7 against'thesurface of'the drum, this-pressure beingdue. in part tojthe weight of the spool andits-supports,.but particularly to the, ac-

tion of the spring 55. -Thechangegear 27; is-so "chosen' that the "surface speed of they drum -66-arid thus the surface. speed ofthe,

spool .barrel or the winding mass thereon,

bears such relation to the speed of delivery ofthe strand from the rolls 5 as to place the winding strand under a predetermineduand I substantial tension. In dealing with wavy or curly fibers such asirwool tops,it is prefeiu able to employ such. a tension as to straighten the fibers and hold themstraight while they are being wound upon thespool. 1 .The changegear 47 in the gear box is also selected to pro vide a rapid reciprocation ofthe' drum: with respect to the strand; delivery guides. such; as to produce a cross-wind, usually of approxi-i mately 30 angle, although this angle-maybe variedin accordance witlithe material being'woun'd.

It will be noted the strand with its fibers substantially parallel Whichisdelivered by the rolls 5} is by the mechanism above described. Woundqvit-hout; having any twistimparted thereto so as to build up upon the spool a cross-wound package. By reason of the compacting action of the trumpet guides, which by their oscillation smooth, round, and compress the sliver, and by arranging the delivery end of the trumpet guides at a dis tance from the nip of the winding elements which is less than the normal fiber length, it is possible to wind the untwisted fiber in highly compressed condition so that a very hard and tight wound package results. By using a plurality of delivery trumpets it is unnecessary to use an excessive length of traverse such aswould be the case in order that they reinforce one another as they do in a twisted strand, and thus it is possible to 7 wind them under high tension.

By windin g under high tension and by applying the proper force for pressing the winding mass against the driving drum, it is possible to build up upon the hollow core or dresser spool barrel a cylindrical package of very substantial length, for example forty inches, and of a hard, dense but porous and uniform structure whose constituent convolutions are laid up under such tension and under such compression that each convolution tends to maintain the position in which it was first laid and thus when the package is removed and placed on end, for example to facilitate pressure dyeing, bleaching or the like,the wet material sustains itself upon the spool barrel and does-not slump down so as to leave a part of the barrel exposed.

Although this package is of very dense,

hard character due to the tension and compression under which it is wound, it may nevertheless be wound at lngh speed, and by the provision of the trunnion devices above described the completed package may readily be removed from the machine and a fresh spool substituted with a minimum amount of for supporting a spool having a rigid barrel and fixed heads, and means for rotatingthe spool whereby to wind the sliver delivered from the gilling means directly upon the spool without twist.
