(Cl. 242-25) This invention relates to winding apparatus, pecially applicable to high speed winding of comand more particularly, to improved apparatus oi? paratively delicate strand material, such as fine this kind adapted for use in winding various wire.

Shifting movement of the disk suflicient for different transmission ratios is permitted by providing the shaft 2| with a spline connection 30 adjacent one of the universal joints.

As indicated above; one of the important fea.- tures of our invention is the provision of means for automatically controlling the speed of the spool I2 to compensate for changes in the eiective diameter of the spool which results from the building up of the material thereon. For the accomplishment of this movable member, preferably in the form of a hollow swinging arm 32, which is adapted to'be I6. The hollow arm 32 may be pivotally mounted adjacent the spool I2 by being provided with a shaft extension 33 which is rockably mounted in and extends through asuitable bearing 34. The outer free end of the arm 32 is disposed in cooperating relation to the spool I2 and may be of nozzle-like form and provided with a discharge opening 35 which is presented to the material on the spool.

For operatively connecting the extension shaft 33 of the'arm 32 with the shiftable lever 21, we provide a stop or ratchet 31 which is pinned upon or otherwise connected to the lshaft and which has an angularly disposed step-like series of teeth or shoulders 38 adapted to be engaged by a. pawllike arm or extension 39 provided on the lever 21.

' A tension spring 40, suitably arranged to act on .tween the arm and the material.

the lever 21, normally holds the pawl 39 in engagement with some one of the teeth of the series 38, and the particular tooth with whichV the pawl engages at a given instant determines the position of the disk I1 with respect to the roller I8.

From the arrangement just described it will be seen that swinging movement of the hollow arm 32 outwardly relative to the spool I2 will cause swinging movement of the ratchet 31 in a direction which may be conveniently referred to as into the plane of the paper upon which this drawing is made, and such movement of the ratchet allows the pawl 39 to successively engage the individual teeth of the series 38. As the pawl 39 moves from one tooth to the next of this series the inner end of the shaft 2I is moved to the left, as seen in Fig. 2, and the point of contact of the roller I8 with the disk I 1 approaches correspondingly closer to the axis of rotation of the disk with the result that the speed of rotation of the spool I2 will be correspondingly reduced.

If the arm 32l were allowed to contact directly with the material on the spool, more or less damage would result to the material, and to avoid this we provide lfor an intervening medium be- This interven ing medium may conveniently be a uid, preferably ar, which is discharged through the nozzle opening 35 at the free end of the arm and against the materialen the spool. Air for this purpose may be obtained from any suitable source, and may be supplied-to the arm 32 through a pipe 40 and the hollow gland 4I into which a portion of the arm 32 may extend. The air is supplied to the arm 32 at 'such pressure that it will be discharged against the `material of the spool at a substantially constant velocity so that the free end of the arm will be in cooperating relation to function We provide athe surface of the material on the spool but maintained just out of contact therewith.

As another feature of our invention we have provided novel means for controlling an oscillating guide which directs the material to different 5 portions of the spool. This control makes possible the use of a winding spool having oppositely tapered end ilanges, as shown in Fig. 2. Before proceeding with the description of this improved guide control, we wish to point out that certain 10 important advantages make it desirable to use a winding spool having such oppositely tapered end anges, but that a satisfactory guide or laying device has not been available heretofore which would permit the use of a. spool of this 15 gripped or fouled adjacent the anges of straight- 20 flanged spools, which tendency is well understood by those skilled in this art.

'I'he strand guiding mechanism with which our novel control may be used, may comprise a. reciprocable bar 45 having av pair of guide fingers 26 46 between which the strand I3 extends. 'Ihe bar 45 may be supported and guided in a suitable bearing 4,1 so as to have reciprocating movement substantially parallel with the axis of spool rotation. 'I'he bar 45 may be normally urged in 30 one direction, for example inwardly of the frame I0, by means of a compression spring 48 disposed between the bearing 41 and a shoulder 49 proi vided on the bar. Movement of the bar 45 in the -opposite directlon may be caused by a fulcrumed 35 the tapered end anges as well as the cylindrical 50 vsupport 56vfor the fulcrum 51 upon which the The support 56 may bein 55 Y lever 50 is mounted. the form of a block which is slidable in ways 'provided by the spaced guide members 53 and 59.

causes an increase in the length of' travel of the 48, such that the strand I3 is properly wound spool.

From the foregoing description and the accompanying drawing it will now be readily understood that we have provided improved winding mechanism wherein the speed o! the spool,is automatically changed to compensate for variations occurring in the eilective diameter of the .spool as the result of the material building up thereon, and that such automatic changes in the spool speed are produced by means which comprises a member in cooperating relation to the spool and adapted to be moved in .response to changes in the depth of material thereon.

It will be understood furthermore that the movable control member which cooperatesl with the spool is prevented from direct contact with the material by an intervening medium, and that the presence of such intervening medium may be obtained by providing the member with an opening which is presented to the material on` the spool and through which uid isk discharged against the material.-

It will also be readily understood from the foregoing description and the drawing that we have provided novel means for automatically varying the travel of an oscillating guide whereby the strand will be properly directed to different portions of the spool, and the use of which novel mechanism permits the strand to be eillciently wound on spools having tapered end flanges. It will be understood, further, that this automatic control lfor the strand guide involves the use of the above mentioned movable control member which is disposed in cooperating' relation to the spool adapted to be moved in response to changes in the depth of material wound thereon.

Throughout the claims and speciiication we have referred to the part upon which the l strand is wound as being a spoo1" and, in this, connec` tion, we wish it tobe understood thatw'by the word spool we intend to include any member or device of suitable nature and upon which the strand may be wound.

While we have illustrated and described our improved winding apparatus in a somewhat den tailed manner, itwill be understood, of course; that the invention is not to be regarded as limited to any particular winding apparatus nor to the winding of any particular strand material, but that the invention includes all modifications and changes which do not constitute a departure from the spirit of the invention and the scope of the l appended claims.
