MATERIAL-WINDING MEcHANrsm or in'gdevice for use'with material Windingma chines. v V p In accordance 'Wltll the features of the 1nvention'there 1s provided-1n one embodiment thereof; a composite. feeding sheave comprising a discihaving a thickness corresponding w the diameter-of the :strandto be re emterp'osedbetweena: pair of knife edge discs of a'idiameter slightlyggreater than the intermediate-tclisc, preferably by a distance not greaterthan the diameter of the stra'nd being fed; thethickn'ess-ofthesheave atits deliverypoint being substantially the same as the diameter of the strand. The composite' sheave is rotatably 'mounted upon. a distributor arm with its delivery point closely adjacent tothejWindingisurface of a rotating sp'ool, the forward end of the" distributor arm being. pivotally secured to a member reciprocating in a path parallel} to the longitudinal axis of'thespool during the winding of each layer thereon: The other end of the arm is tapered and its-movement in a lrorizontalp'lane is limited only by .tWO:

spacedstationary stopjmembers so thatlit may move freely to and from-the'ivinding arbor during the reciprocations of the for Ward-end ofthe arm; At the end of each reciprocation of the composite sheave, which may be built up according to the size'of strand being Wound, the 'en'd turni will be placed snugly againsttheinnerfac'e oft-he spool flange 'or'at a definite predetermined point on thespbolb a i It is bel-ieved that the invention Will be clearly understood from the -fol-1oWi11g-de-' scription taken in connection With'the ac companying ,drawingsilliistrating one embodiment of theinvention, in which 0 a Fig; 1' is a fragmentary plan view of; a

Looselymounted in a depending' port-ion 'l liofthe head block 12 by a suitable pin or 7 screw 15 is an arm- 16, wh'ich i's reciprocatedlby -any suitable means (not shovvnf,,forinstance the v means disclosed in my 'above mentio'ned pat ent, in a suitable slot-'17 formed in the frame 11 of the inding machine.

The slide 13 projects; forwardly oi the head block 12 and lies in the same-11 0mm the'slide13 byla pin 22 and restsflupon th'e top surface of the-slide 13. The'rear o'fthc arm 21 is tapered and is lim-ited in'its hori zontal, movement by two -statijer'ia rypins 24 'one on either side thereof, vvhichpi'nsa're secured to a bridge. member 25"vvh-ich-may be suitably fixed? to the frame of the machinel The pins 24 restrict the movement of thetape'red .end of the arm in a: direction lengthwise of the bridge 25, but" permit it to move freely laterally thereof. Mounted upon the forward end of the feeding arm 21 just behind the pivot pin 22 is a feeding sheave 26 supported by a bracket 27 suitably secured to the feeding arm 21. The

, sheave 26 is so positioned that the axis of that the guiding surface of the feeding.

Y sheave corresponds to the diameter of the flanges of'the spool.

wire being wound so that the end turns of the wire being wound can be snugly placed against the inner sides of the heads or flanges of the spool. It will readily be seen that by providing a sheave wherein the peripheral guide surface may be changed to provide a surface of a width equal to the diameter of the wire being wound, the wire will be placed close to the inner sides of the This results in preventing any pockets or ridges being formed during the winding operation, which would occur if a guide surface designed for a large wire were used for a smaller diameter wire, since the wire would move over to the inside face of the flange of the sheave in a direction opposite to that which the feed-' ing arm 21 was moving, thereby preventing the end turn of wire from being placed snugly against the flange of the spool.

In operation the head block 12 is moved first toward one flange ofthe spool and then toward the other by the reciprocating arm 16, and at the end of each movement toward either flange 32 of the spool 33 the slide 13, is stepped .backwardly, a distance equal to the diameter of the wire being wound. During the sidewise movement of the head block 12, the'forward end of the arm 21 carrying a sheave built up according to the diameter of the wire being wound, through its pivot connection 22 with the slide 13, is carried along therewith, the opposite end being held from movement longituclinally of the spool by thestationary pins 24, but sliding forwardly and backwardly successively, thus pivoting at a plurality of points located lengthwise of the arm. These latter movements are necessary due tothe varying distance between the axis of the sheave and the stationary pins 24 during operation, as is indicated by the dotted position of the feeding arm 21 (Fig. 1). As

' indicated clearly in Figs. 3 and 4-, the outside faces of the knife edge discs 30 are tapered toward their peripheries as indicated at 3 1 at such an angle as will bring the tapered surface thereof at the end of a sidewise movement of the arm 21 into engagement with the inner face of the associated spool flange. Due to the shallowness of the'strand groove andthe substantially knife edge formation of the outer discs, the strand contacts with 'the inner face of the head simultaneously with the outer disc affected. As the thickness of the sheave at its delivery point is substantially the same as the diameter of the wire being wound, the wire is placed snugly against the inner faces of the spool flanges at the endof each reciprocation of the head block 12 (Fig. a).
