EDGE WINDING COMPRESSOR FOR WINDERS Patented .lune 8, 1926,

tf1-fic EDGE-WINDING comennssoa non tympans;

Application filed March 17, 1921.1.. Serial No. 699,683.

This invention relates to Winding machines, for example textile winding machines havingV a driven spool or Warpbeam upon. which the winding mass is in operative Contact with a driving rictional surface, such as the usual tractor drum or roll or belt, or other device depended upon for simultaneous rotation and compression ot the Winding.

ln machines ot the kind referred to, practical considerations ot variations from the intended spacing and trom accurate perpendicularity to the axis ot the spool or Warpheam heads dictate the use ot a driving or tractor drum or like trictional drivingsurtace sufficiently narrower than the smallest expected tree space between the head flanges to permit the heads to st raddle the driving sui-.tace `without possibility ot binding. The winding space on the ivarp-bcam, spool or jaclr spool may exceed the driving .surface in width by an inch or more in practice.

This neither prevents nor limits the Windingl upon the spool or beam, hereinafter relierrcd to as the winding container, but does result in producing `rivound mass which, though laid on throughout the greater part of the winding space under uniform conditions of compression, has end sections or edges laid on ivithout the benel'it ot constant compressive Contact with the driving sur- Aface. Consequently these edge regions tend to irregularity, usually increasing in diameter YfasterI than the normal parts ot the Winding, and there-tore containing longer Windine's than normal parts of the Wound container ivound by the same nun ber ot revolutions of the Winding container, rlhis delect, which is serions in any Wound package, particularly objectionable in the case ot ivarps or Warp sections Wound for slashing or for direct use in a loom, since it results in a warp having selvage regions, or the edges of sections, slacker and longer 'than the middleI regions. Corrective treatment in the Slasher or loom is practically impossible Without serious ivaste of yarn; and v'vavy or curved places or slack selvages result in the cloth.

Objects oft this invention are to obviate such detects otwound packages by providing to maintain substantially uniform compression ot the Wound mass throughout the space between the heads or flanges of the ivound container during Winding; to provide edge-vvindingl compression devices auxilia, y to the Wound mass driving and compression means adaptable to existing Winding `ma; chines Wit-hout change; to provide auxiliary devices of the kind indicated capable officio,- operating with spools `or Warp-beams having heads not accurately perpendicular to their axes, and adapted to maintain even compression When the Wound mass is not accurately cylindrical, or When` there isl axial reciprocation or creepingoit the Winding mass;

and to provide for removing the, finished packages and beginning new vwindings Without interference by the auxiliary device With rapid removalsand replacements ofv the con tainer.

rllhe invention willv be explained in connection with preferred Jorms only oij the devices chosen for illustration in the accompanying drawings, in Whichz- .i

Fig. 5 is an elevation, showing the roll restrained, ot a modified auxiliary compressorv roll; and A Fig. 6 is a longitudinal section et the device o Fig. 5, showing the roll released for operation.

Referring now to Figs. 1 and 2, the Winding machine may coi'nprise any or all of the usual agencies, such as guiding combs, lease forming devices, supports for the drop-,Wires of breakage-actuated stop-motion devices, including a pouurfrelease device; a warping reed, and a delivery guide roll', all supported by the end trames l., all familiar in the art, and not herein shown.` Also as usual inthe art, the machine includes a tractor-roll or belt, shown as the drum '2 on the horizontal shaft 3, which may be driven in any usual Way, Jfor example by a belt, not shown, at a constant peripheral speed. Pivoted on shaft 4, the machine includes supports such as the radius-arms 5 for the Winding container having bearing notches 6 or other ippropriate bearings for the spindle 7 of ie spool or warp-beam 10 having heads 12 straddling the ends of drum 2, against which the surface of the winding layer rests with a compressive force determined by the weight of the container 10, and, if desired, by auxiliary weights 13 adapted to be hung on the supporting arms 5.

The winding yarn w thus runs from the guide roll, not shown, on to the wound layer of the container 10 at the opposite side of a layer from the point of compression and exertion of the necessary frictional driving torque by drum 2. The length of the container 10 between its heads 12 necessarily exceeds the length of drum 2, and this results in wound regions m, m, which, without assistance, are inevitably soft, spongy, enlarged and contain more yarn than the normal middle portions of the winding which have been laid under the constant compression of drum 2. The regions may be of different and irregular widths, due to irregularity'of the heads 12 or slow reciprocal axial motion of the container 10` This invention provides for the compression of the regions x to a predetermined degree substantially conforming to the remainder of the winding, by means acting upon the edges of the winding to compress them variably according to excess of diameter of the edge windings. Preferred instruments for this purpose, as shown, are arranged to compress edge regions exceeding in diameter the central regions at a point, as measured along the winding layer, more remote from the place of contact of the yarns vw with the previous winding than is the place of contact of the last layer of yarn with the drum 2, in order not to apply compression to a layer insufficiently wrapped about the winding surface by the tension of the yarn. The instruments preferred and shown are also caused so to act upon the wound surface of the container as substantially to have no effect upon the pressure of the winding upon its driving and compressor surface, such as the drum 2, and are provided to be readily removable from contact with the container, and may be arranged to bear upon the winding with reduced pressure whenever the machine stops automatically or at will ofthe operator.

These instruments comprise freely rotatable and axially movable rolls 15, 15, and mounting and positioning mechanism for these rollsY adapted severally to maintain them in contact with the Winding mass and the container 10 under a predetermined relatively constant pressure acting on the upper side of the winding periphery, the direction of the pressure being toward the center of the container 10.

ln order to provide for the equipment of existing machines, and. for other purposes,

it is preferred that the devices for holding and moving the rolls 15 shall be such as to be readily attached to the frames of existing machines, but it will be understood that any construction providing for the effective position and effective pressure on these rolls may be employed. As shown in Figs. 1 and 2, the preferred devices comin-isa attachable bearing plates or blocks 1G alike but symmetrically formed for each side of the machine, as best shown in Fig. 1, and having holes for attachment screws or bolts 17 for ready adjustment to conformity with containers of different sizes, or diderent arrangements of the drum corresponding to the drum 2 of the drawings. Plate 16 provides a bore 13 and an integral or attached sector 19 having a slot 2O concentric with the bore 18 in which hole and slot respectively is held a stud shaft 21 and the hold-down bolt 22 projecting from a bracket arm 23, in turn providing a bearing for a shaft 25 about which the roll 15 can move as a center. lt will be observed that the position of the shaft 25 may be adjusted along the sector slot 2O suitably to control the locus of motion of the rolls 15. A preferred form ot mounting permitting this motion of the rolls 15 and permitting control of the pressure upon the rolls 15 as presently explained, comprises `a radial arm 26 integral with or attached to the hub of a sector gear 27 in turn having a bearing on the shaft 25. The structures 26, 27 may be held against endwise movement on the shaft 25 by a head 28 integral with or attached to the inner end of the shaft 25.

The attachnient block or plate 16 is provided with an inwardly projecting lug 3() providing a bearing for a short shaft 31 projecting outwardly through a hole in the frame 1 and having fixed on its inward end a gear sector 32 meshing with the gear 27.

The outer end of the shaft 31 carries one member 33 of a pin or other unipositive clutch, of which the other member 341 may be integral with or attached to the hub of a counterweight sector 35 confined against freedom of longitudinal motion on the shaft 31 by a collar 36.

The radius arm 26 at a suitable distance from the center 25 to clear the head flange 12 of a container of any expected diameter is provided with a rigid attachment, as shown, in the .form of a pair of shoulderbolts 38, for an inwardly extending arm 39 in turn carrying an angle bracket casting 40 upon the inner end of which there may be suitably mounted a holding or bearing block 411 for a horizontal shaft 42, Fig. 3, upon or with which the roll 15 turns.

It vill be understood without further explanation that the above mentioned structures are provided at each side of the machine preferably in like form, but syminet-rically right andy lett handed for the right hand and lett hand 'frames l respectively. l

Reterring now to the roll l5 maybe termed as a sleeve having its tree end closed by a screw plug having a polisliexijl 'tace 51, and having an internal bearing sleeve to talte over the sha'rt l? upon w "'h it held by the washer 53 and screw again. the thrust ot a light compression spring housed in the space within the sleeve 15, between the end oit the bearing sleeve 52 and the end ot the block el. rllliis arrangement is sach to provide axial itreedoi'n ot movement for the sleeves 15 and 52 through the range permitted by the con'ipressed 'state oit he spring and the washer 53.

lVhen a new spool or beam is to be mounted or a 'toll spool or beam is to be dotted, it is desirable to be able to remove the rolls 15 from their loperative position; this is preterably accon'iplished by locking the said rolls in their' inner position ttor which purpose a pin 57 may be provided in the block al, to takel into any one of several bayoiiehclutch slots 58, 59. Preferably these clutch slots are provided by an inclined slot part 59 penet ating the full thickness ot the sleeve l5 and joining a breached-out slot 58 notA penetrating to the surface ot' the roll 15.

is best shown in Figs. 5' and 6 the auxiliary compressor roll shatt 61 may be arranged t0 have endwise freedom ot movement, tor the purpose ot providing tor endwise motion ot the rolls 15. ln this case the block al provides a sliding bearing bore (30 t'or the reduced end oit' the roll shalt-t 61, which may have a. stop collar 62 and an enlargement 68 co-operating with the compression spring G4; housed in an enlarged bore G5 in block ll. The outboard end ot the enlargenient 63 may be received within a recess t--l in the end of the roll 15 which is provided with an internal bearing sleeve (S6, and is without snbstantial freedom ot motion in respect to the shaft 61, upon which it is held by the washer 67 and screw4 65.

The counteiwveight sector 35 is normally displaced against gravit-y by its connection to the sha't't 3l, and according to its position transmits through said shaft a variable pressure co'untervailing in part the variable pressure exert-ed upon the rolls 15 by the Weight ol' the roll supports. It will bel observed that the opposite motion toward the upper dead center or central position ot eccentric weight ot the roll support 26, 39 accompanied by approach of the connterweight 35 to its dependent position ot rest, so that the 'effective pressure on the roll 15 is substantially constant.

lt is desirable to remove this p sessure 'when the winding stops. This may be provided tor by a hole 3,6 in the sector 35 and a cord 37 connectedthrongh pulleys or bellwound mass.

In operation the rolls 15 rest npon the winding and compressed layers of the nor-v inal part ot the winding throughout the greater part ot their contact with the wound mass upon the normal parts of which their additional pres ire is without eilect. The edge windings desired to be controlled occupy, as shown atx, only a small traction ot the width ot the compression rollers 15. lt there is substantial slack in winding, the regions m will grow to a slightly larger dialneter than the adjacent parts ot the winding and when this happens the whole structure 15, l-O, 29, 2G, Q7 etc., is rotated ab nt the center 25 by the weight ot these parts except so much ot this weight as is connterbalanced by the thrust ot' the sector 35 communicated by the gear 32. When the whole thrust on the auxiliary rolls 15 is carried by the narrow regions sa, the local compression is considerable. This condition continues until the rolling action on the softening edge winding has produced a sutlicient compression again to bring ,the adjacent edge winding into conformity with the diameter ot the remainder ot the winding.

lt' the heads ol the winding container are not accurately perpendicular, or il' the winding container reciprocates slowly or rapidly in the direction et its axis, the longitndi ally and oppositely ,spring-pressed rolls 15 are able to follow this motion, so that the polished ends 5l of the rolls ran in close Contact with the inner surface ot the heads 12 of the winding container. It has been found in practice that there is no consider able resistance to` the turning oit the warpbeani or spool by contact with the polished heads oli these rolls. rlhis again .is dne to the axial 't'reedoin ot motion oit the rolls; they yield to pass obstructions which otherwise would lock the heads 12 against motion.

When a lull spool or beam is to be removed.l the auxiliary rolls and their nionntings are turned back out ot' the way by pulling on the connections 37; when the eccentric center of gravity ot the roller supports Q6, 39, etc., has passed the vertical from shafts 25u the auxiliary rolls 'will remain in the idle position, the clutches 33, 34, permitting the weights 35 to swing to their idle dependent position', the operative position ot all the parts being restored when the rolls 15 and their supports are again swung forward into Contact with a new windin.
