Application med may 31,

This Ainvention relates to mechanism for and al method of handling yarns or the like, being especially useful in connection with the manufacture of carpets or rugs of the Axminster or similar types, such as produced on moquette or other pile fabric looms, and provides a method and a simple and effective mechanism vfor carrying out the same and whereby the yarn spacing and holding means may be applied to yarns or the like to maintain them in their established pattern or other arrangement upon a spool or other support until they are to be further k manipulated. This application is a continuation as to certain commonsubject matter of our copending application, SerialNo. 543,589, tiled March 14, 1922, now Patent #1,512,928, dated October 28, v1924.

Iii the accompanying drawings disclosing one embodiment of our invention chosen foi-.purposes of illustration and illustrating one manner of practicing our nietliod,-

Fig. 1 is a plan viewvshowing a portion of a spooling machine and related mechanism embodying one form of our invention, portions of the upper presser'roll being broken away;

Fig. 2 is a front elevation of the mechanisni shown in Fig. 1; i

Fig. 8 is a vertical section through the mechanism shown in Fig. 2; i

kFig. 4 is a detail view upon an enlarged scale.

Referring to the drawings We have illustrated one forni of our invention as vapplied to a well known type of spooling machine such, for example, as thatshown in the patent `to Hathaway and Lea #1,152 380, it beingunderstood that ourinvention is not limited to this or any particular construction of spooling machine nor in its broad aspects to a mechanical attachment to or vassociated with a spooling machine of any form or construction.

The illustrative forni of spooling machine shown includes the side frame members 1, 1 and the cross Support or member 2. Said side frame members carry suitable supports not necessary herein more fully to Show or describe for rotatably mounting a spool 3` and one or more frictioiior presser rolls 4 Jfor yieldably engaging the yarns as they are wound on to said spool. Said spool is adapt- 1924. l `serial Nu. 716,881.

ed toreceive winding ,movement in either direction at will-'or to be stopped, power being supplied iii any suitable manner as by oppositely drivenbelts (not shown) which ma be shipped respectively from the loose fpul cys 5 or 6 lto, the fast pulley 7 l(See Fig. 1). The spool 3 is preferably driven through suitable gearing' or other connections from the driving shaft whereon said pulleys are mounted and operatin the gear 3a l(Figs. 1 and 2) upon the Spool s aft.

The yarn strands 8, or sets of strands if twoor more be employed in a group, in the illustrated form of our invention, lead from ,the bobbin frame (not shown) on to said windingspool 3 Ypassing over a guide bar 9 carried by brackets projecting outwardly and upwardly from the cross member 2, see Figs-2 and 3. yIntermediate said guide -bar and the spool` the yarns pass betweenrthe upper portions ofthe pins, pegs, teeth or the like 10 =which, together with the crossr baror holder 11 in Whicht'hey are supported inzupright position, comprise the yarn guiding means or reed indicated. generallyv at 12.

'.Theyarnspreferably also pass over la. vsecj .peg or", pegs 4ofthe reed. As best seen 'inV Fig. l Leach peg with the exception of the central one,`or a few at each side of such central peg, includes a straight upper portion 10, an inclined. portion 10b below the Same, and a straight lower terminal or base portion'lOc (see Fig.v 2) substantially parallel with but-offset from the straight upper portion. Said pegs are o'set by increments varying progressively fromfthe center to the endofthe reed. As herein shown, the ofset of the .pegs lis outward toward the respective ends wherebyy a reed is provided having awider bottom than top portion, but it will .be understood that in certain instances, the

Y reed than its top portion.

The form of reed as shown is'adapted for use fwhere aser-ies of: yarns or Vthe like-"is placed upon a support such as Vthewinding lspool herein shown, which support is of a offset Yinay be in the reverse direction, that is, inwardly `romeach end toward. the center to provide a' narrower bottom portion for the different length than that of the? yarn sepaf rator, comb or endclvampwhich isV tobe positioned upon the yarn ends.l` In other words, the pitch of the yarnsupon the spool i s""d ill'ere nt' 'from and herein Yless 4than the pitchbetween 'the yarn receiving lportions ojt tliese'parating device. -Suchfdiderencein lengths between 'that of the ya-riiQ-holding space on the spool and in theV separator or y clamp is usefuhtor example, wheref'a plurality of spools is 'to be placed serially end to endv on a tube, trame foruseinm'wide' worin??

In some instances it is desirable to crosswind the yarns upon the spool. Preferably therefore we provide means for producing a relative reciprocation between the yarns and the spool in a direction axially of the latter during the winding` of the yarns. In the present form of our invention we have shown the cross member 2 as having a slidable support in suitable bearings 30 upon the side frame members 1, 1. Said cross member 2, which herein carries the reed 12, the comb 14, and associated parts seen in Fig. 2, may thus be moved longitudinally and substantially horizontally thereby to reciprocate the yarns relatively to the spool to cause them to be wound upon the spool at an angle.'

Any suitable mechanism may be employed for reciprocating said cross member 2, and

we have herein shown for that purpose, referring to Figs. 1 and 2, a bevel pinion 31 fast upon the yarn spool shaft and meshing with a bevel gear 32 at the upper end of a substantially vertical shaft `33, see 2, supported in suitable bearings upon the machine frame. Said bevel pinion 31 and bevel gear 32 may be of any desired ratio but are represented as respectively 1 to 2 whereby one complete reciprocation will be imparted to the cross member 2 for each two turns of the spool.

At its opposite or lower end said vertical .shaft 33 is operatively connected to a short horizontal shaft 34 through meshing bevel pinions 35. Said horizontal shaft is rotatably supported upon the machine frame and has fixed upon its forward end a crank plate having upon its outer face a slot 37 in which is adjustably positioned a crank pin 38. Pivotally supported upon said crank pin is one end of a link 39, the opposite end of which is pivoted as at 40 upon the cross member 2. Preferably a clutch .d1-is provided having an operating member 42 and by means of which the crank plate and associated reciprocating mechanism may be thrown optionally into or out of operation.

When the cross winding mechanism is not to be employed the cross member 2 may be locked in normal position for straight winding by suitable mechanism, such as the latch 4-3, see F ig. 2, pivoted upon the machine frame and engageable with a notch in the periphery of the crank plate, in which position it is retained as by the spring 44. During operation of the cross wii'idingmechanism .said latch may be swung downand across center against the stop 45, in which position also it will be held by said spring.

It will be understood that any desired type ofv cross winding `may be provided by varying the ratio vbetween the speed of rotation of the spool and of the reciprocatory movement imparted to the cross member 2. By the mechanism shown the y rns will be wound in double looped form, somewhat in the manner of a ligure 8. The eXtent of the reciprocation and consequently also the angle or extent of the cross winding may be regulated by adjusting the throw of the link 39, the crank pin 38 being shifted for this purpose in the slot 37 of the crank plate.

From the-foregoing description it will be understood that our method of positioning a series of yarns or the like in a separator where such' separating means is of a length different from that of .the yarn support, and where therefore the pitch of the series of yarns differsfrom that of the yarn receiving portions of the separator, includes the steps of assembling the yarns in substantially parallel relation upon a .suitable support such as a spool, whether straight orl cross-wound thereon, or in providingfr such support or spool Awhereon the yarns have previously been positioned or wound, and subsequently'varying the pitch of the yarns by shifting them laterally, Youtwardly or inwardly as the case maybe, and in opposite directions from the central yarn ,or yarns of the series and by increments varying progressively from said center, and in finally positioning .the yarns so shifted, and whose` pitch has thus been made to conform to that of the yarn receiving portions of the separating means, in said separating means 'by relative movement between the same and the yarns.

Our invention is not limited to the illustrative embodiment thereof herein disclosed.
