Referring to the drawings wherein for the purposeof illustration a preferred embodiment of the invention is shown the numeral 5 denotes the shaft of the winding reel, one end of which is supported by a fixed bearing 6 in the front wall 7 of gear housingS and a bearing 9, Fig. 11, mounted on adjustable cross bars 9. The cross bars are attached to side walls 10 of the housing by bolts 11 for vertical adjustment and studs 12 mounted in lugs 13 attached to the side walls, have bearingv engagement with the upper edge ofv the cross. bars for adjusting the cross bars downwardly andupwardly when thebolts 11 are loosened. The opposite end of shaft 5 is supported in a conical bearing 14 mounted on the upper end of post 15. Post 15 is pivotally mounted at 16 on the base frame 17 to swing outwardly from .the end of shaft. 5. The post is actuated by a pneumatic cylinder 18-pivotal- 13/" attached at 19 to the base 17 .and the piston of the cylinder is attached at 20'to the post. The cylinder is connectedto a sourceof compressed air, not shown, for, movingthe piston in opposite directions to swing the post. and bearing 14'intoand. out-of supporting position.

An angularly disposed U-shaped frame 21 attached to the.

end of base 17 limits the outward'movement of post 15 and a bumper block 22 attached. to the base-retards the outward movement of thepost and absorbs the. shocks.

A series of disks23 are mounted onshaftjS in spaced apart relation and each disk has one face provided with a series. of radial grooves 24, more clearly shown in Fig. 6, in which are slidably mounted extensible arms 25 having bifurcated ends 26' for attaching paddles 27 to the arms.

and extend through

slotsv

36 and 37 in. the arms 25 and,

disks 23. When the toggle joints are moved in one die. rection the arms 25 are extended beyond'the edge of the disks thus moving the paddles 27 to. an expanded positionandwhen moved in the opposite direction the arms,

25 are retracted thus moving'the paddles to a contracted position.

A collar 38 is slidably mounted on shaft 5 adjacent the disk 23 confrontingthe end wall 7 of gear-housing.

8. A series of lugs 39 project radially from the collar and areconnectedby links 40 with the pivot bolts 35 ofthe toggle joints of the end diskadjacent the collar.

The collar 38 is reciprocated on the shaft 5 to actuate, 1 the toggle joints by a yoke 41 which straddles the collar.- Asplit ring .42 is mounted on the collar and has project-,- ing pins 43 which engage in slots 44 formed in the arms, ofitheyoke to establish connection between the yoke; and collar. The yoke is aflixed to the upper end of ,a:

lever 45"pivotally mounted as at 46, to a bracket 47 attached to the wall'7 of the gear housing, Thelower end of lever 45 is pivotally connected '.'to piston rod v48 of pneumatic cylinder 49 pivotally attached to the base.v frame 17. The cylinder is connected to a source of compressed air to move the. piston rodin both directions so' as to move the lever 45 and" operate the yoke to slide the'collar 38 back and forth.

A spindle frame or rack 50 is attached totherearof. the base frame 17 "consisting of an upright 51.supporting one end of a cross bar 52having its oppositeend attached to the top of gear housing 8. The cross bar 52 is inclined in a forward direction and attached tothe top thereof is an angle bar 53'on which are mounted a series of spindles 54, in spaced apart relation, forreceiving the yarn packages or spools 55, shown in Fig; 4, the-spools having the usual flanges 55. A horizontal bar 56 is supported above the cross bar 52 by end members 57 attached to the ends ofthecross 'bar-and attachedtothebar 56, at spaced apart intervals, are depending dividing plates'58"and between'the plates in vertical alihementwith the' spindles Patented July 31, 1956.

- unwound from the spools.

greases 54 are depending hooks 59 for guiding the yarn as it is Attached to and extending from the forward edge of cross bar 52 are a series of brackets 60 having spaced guide rollers 61 for supporting the reciprocating guide rod 62 from which extend a series of guide arms 63 having eyes 64 at their outer ends through which the yarns are threaded.

As shown in Figs. 9, 10 and 11 the gearing for operating the Winding reel is contained within the gear housing 8. Mounted on the shaft of the reel is a double groove pulley 65 which is driven by a belt 66 connected to a double groove pulley 67 mounted on idler shaft 68. A pair of change speed pulleys 69 and 70 are mounted on the idler shaft and are driven by a belt '71 connected with the change speed pulleys 72 and 73 mounted on shaft 74 of a motor 75. One end of reciprocating guide rod 62 extends through an opening 76 in the front wall 7 of the gear housing being pivotally connected at 77 to eccentric 78 mounted on the upper end of shaft 79 journaled in

brackets

80 and 81. A bevel gear 82 fixed on shaft 79 below bracket 80 is in mesh with bevel gear 83 mounted on shaft 84 journaled in

bearings

85 and 86. A sprocket wheel 87 mounted on shaft 84 is driven by sprocket chain 88 connected to a drive sprocket 89 mounted on the reel shaft 5. An idler sprocket 90 engaged with the sprocket chain is provided to take up the slack in the chain.

A locking mechanism for retaining the yarn packages or spools on their spindles is shown in Figs. 4 and 5. A lock bar 91 extends longitudinally of the spindle frame above the cross bar 52 and to the rear of the spindles 54 that support the yarn spools 55. The bar is provided at its ends with pivot pins 92 journaled in brackets 93 attached to the end members 57. An arm 94 attached to and depending from the ends of pivot pins 92 connects with one end of a coil spring 95 having its opposite end attached to a bracket 96 secured to cross bar 52. The tension of coil springs 95 normally swing the lock bar 91 so its lower edge is disposed over the flange of the yarn spool 55, thus retaining the yarn spools on their spindles and preventing accidental removal of the spools from the spindles due to the pull of the yarn on the spool during the winding operation. A dog 97 aflixed to one of the pivot pins 92 and depending therefrom is adapted to be engaged by one end of a latch lever 98 when the lock bar 91 is swung rearwardly and the latch lever is in a horizontal position thereby holding the lock bar free of the spool flange so the spools may be removed from the spindles. The latch lever 98 is pivotally suspended from bracket 93 by arm 99 attached to the lever intermediate its ends and is normally disposed in a horizontal position. A latch release lever 100 having its upper end disposed beneath the outer end of the latch lever is pivotally mounted in a bracket 101 attached to the top of gear housing 8. A yoke 102 extending laterally from the lower end of lever 100 engages with an arm 103 attached to yoke 41, so that when yoke 41 is moved to expand the paddles of the reel the latch release lever is moved to release the latch dog 97 to permit the lock bar 91 to assume a locking position under the action of springs 95. The actuation of the latch'lever to release the latch dog is performed by plate 104 attached to the upper end of release lever 100 which has a beveled edge 105 in engagement with the lower edge of the latch lever 98 so that when release lever 100 is moved the latch lever is raised by the beveled edge of plate 104. A shoulder 106 at the upper end of the beveled edge limits the movement of the release lever in one direction and a coil spring 107 having one end attached to plate 104 and its opposite end to cross bar 52 swings the release lever in the opposite direction when yoke 41 is moved to contract the paddles of the reel.

The pneumatically operated cylinders 18 and 43 are controlled by conventional foot operated valve mechanisms for admitting compressed air to either end of the cylinders.

In operation, the packages or spools of yarn are mounted on the spindles 54 and the strands of yarn drawn from the spools over hooks 59 disposed above the spools and then threaded through the eyes 64- of guide arms 63 before being attached to one of the paddles 27 of the reel. The reel is rotated by starting the motor 75 which drives the reel shaft 5. During the reeling operation the rod 62 is reciprocated so that the guide arms 63 move the strands of yarn back and forth to perform the skein formation in the usual manner. When all of the yarn from the spools has been wound on the reel cylinder 49 is actuated to move the collar 38 to the right which through operation of the links 40 and connecting bars 34 operates the toggle links 31, 32 to simultaneously retract the arms 25 of disks 23 to contract the paddles 27 so the skeins of yarn may be easily removed from the reel. To permit the skeins to be removed from the end of the reel, cylinder 18 is operated to swing post 15 to the left or away from the end of the reel thus removing the bearing 14 from engagement with the end of shaft 5. After removal of the skeins of yarn the cylinder 18 is operated to move post 15 to the right and bring the bearing 14 into engagement with the end of shaft 5 and then collar 33 through operation of cylinder 49 is moved to the left to move the paddles 27 to expanded position. When the paddles 27 of the reel are expanded by movement of collar 38, release lever 100 for the latch lever 98 is moved by arm 1G3 attached to yoke 41 to release the latch lever from engagement with dog 97 thus allowing spring to swing the lock bar 91 so its lower edge engages over the flanges of the spools 55 to retain the spools on their spindles until the winding operation is completed. When the paddles of the reel are contracted, release lever is moved by spring 107 to allow latch lever 98 to swing into engaging position with dog 97, as the lock bar 91 is manually swung outwardly to a non-locking position. Thus, it is seen the latch lever holds the lock bar in a nonlocking position while the empty spools are removed from the spindles and replaced with full spools of yarn.
