14 Claims.

An object of the invention to provide a ma- 1' w chine which will be adjustable for the winding of solid continuous ring cores of any diameters between the minimum and maximum diameter limits of the machine, and which will also wind such rings with any desired size, gauge or type of 35 wire or other winding material, ranging for instance from one mill to inch flat ribbon wire in the case of rheostats, and further to provide for an infinite variation of pitch or leads within the minimum and maximum limits of the mam) chine, ranging for instance between 15 to 3000 turns or convolutions to the ring.

Another object is to provide a machine of this character which will be extremely accurate in operation and in predetermination of the de- 25 sired winding, will be rapid in operation, and

will not require highly skilled operators for tending to the machine.

In winding rheostats great precision is necessary so that the winding will be evenly spaced 30 with the proper pitch or lead between the turns,

and the windings must be sufllciently tight upon the ceramic core so that they will lie flat upon the core surfaces and will not become displaced.

Inaccomplishing this there must be a tension or pull upon the wire as it is being wound suflicient to bend the wire sharply about the corners of the core at the same time pulling it in flat re-" lation to the core surfaces, and itis an object of the invention to provide means whereby such 4 tensionai pull may be provided, and which may be the size of ring, wire and pitch) before respooling the bobbin.

It is further proposed to provide bobbin respooling means by which bobbins may be respooled' during the winding of the rheostats, and further to provide counter means in connection, with the respooling means to predetermine the amount of wire wound on the bobbin, thereby eliminating waste of wire through the spooling of short lengths.

' leads, and tensions for different sizes and character of wires. In particular it is proposed to pro vide pitch adjusting means which can be set to a predetermined pitch before the winding operation starts, or if desired can be changed even while the machine is in operation. It is proposed in connection with the tension adjusting means tq provide a calibrated dial on the winding shuttle by which the proper tension may be pre determined and maintained.

With the above and other objects in view, an embodiment of the invention is shown in the accompanying drawings, and this embodiment will be hereinafter more fully described with reference thereto, and the invention will be finally pointed out in the claims.

In surrounding relation to the top flange 26 of the post 26 there is provided a cover plate 31 of ring shape, having a slot 32 disposed at the rear in alignment'with the slot 23 of the post 26, the inner periphery of the'plate 31 being spaced from the outer periphery of the flange 23 thereby providing a circular slot 33. i I

The plate 3| is mounted upon a segmental circumferential wall 34 extending from one wall of the slot 32 to a point in spaced relation to the forward central point of the plate 3|, upon a segmental wall portion 35 extending from the other wall of the slot 32 to one of the pair of a segmental wall portion 36 extending from the forward line of the gibs 36-36 to a point spaced from the'forward central point of the plate 3|. the segmental wall portions 34, 35 and 38 being secured to the base l3 by means of bolts 39, which bolts also secure the cover plate in place.

A ring gear supporting bearing wall comprises two segmental sections arranged within'the wall portions 34, 35 and 33, one segmental section 40 extending from the right hand-side of the slot 32 to the forward line of the gib members 3636, and the other segmental section 4| extending from the left hand side of the slot 32 to the side edge of the right hand gib member 36 and in flush relation to the end of the wall portion 35. The wall sections 63 and are secured to the .base l3 by means of suitably spaced screws 42.

The wall sections 40 and 4| are provided at their inner peripheries with upwardly projecting flanges l3 and II, respectively, forming an annular bearing for the inner periphery of a worm ring gear mounted upon the wall portions 46 and II, this ring gear being supported upon a series of radially disposed antifriction rollers 46 disposed in pockets 6" in said wall portions and secured against longitudinal displacement by set screws 41 engaged upwardly in the wall portions 40 and ll, and having studs 48 at their upper ends engaging annular grooves 49 in the rollers.

The ring gear 46 is provided at one point with a projecting pin 56 which operates an automatic mechanism for stopping the machine at a pre- 76 provided in their inner peripheral surfaces with slots i through which this pin moves. The shank of the pin 50 is threaded and may be selectively engaged in one or the other of three threaded holes 58 and 5|) provided in the ring to vary the point at which it actuates the stopping mechanism. Its degree of projection may also be varied by screwing it in or out to secure fine adjustment of its actuation point, as will hereinafter more fully appear.

A radially disposed arm 52 is secured to the ring gear 45 by means of screws 59, the inner end of this arm extending beneath. the slot 33 where it is provided with a square hole 54 .for interlocking engagement therewith of the clamping means of the ring to be wound, it being understood that as the ring gear is rotated the clamping means is rotated and rotates the ring,

, the ring being rotatably supported upon the post 2t, and which ring supporting and clamping means will be presently more fully described.

The plate M is provided at its forward central portion with a rectangular cut-out 55 and the base plate I3 is provided with a pair of parallel T-slots 56-55, and within which cut-out and slots the driving worm for the ring gear and its supporting bearing is mounted. A slide member 51 having a pair of spaced bearing standards 58-58 at its upper side is provided at its lower side with a pair of T-bars 59-59 engaging the T-slots 56-56 of the base it, the bearing standards and the bars being secured to .the slide. ,member 5! by screws 69. A worm 68 disposed between the bearing standards 59-58 has its shaft 62 journaled in said standards, one end of this shaft having secured thereon one member 63 of a universal joint drive connection, the other the worm with respect to the worm ring gear 45, e

and for this purpose the T-bars 59-59 are provided at their under sides with posts Ill and H, respectively, to which springs 12 and 13 are connected at one end, the other ends of these springs being connected to a post It secured tothe underside of the base plate 13 between the T-slots 56-56, and which springs normally tend to pull the slide 51 and the worm gear carried thereon out of engagement with the worm ring gear 45.

For the purpose of engaging the worm with the worm ring gear a cam lever 15 is pivotally mounted by a shouldered cap screw I6 upon the base 13 between the T-slots 56-56, and which upon being pulled outwardly from the position shown in Fig. 2 will have its cam surface 'II engaged with a bearing portion 18 upon the slide plate 51, and will force the slide plate inwardly, meshing the worm 6| with the worm ring gear 46, in which position the slide and worm are retained by means of an automatic latching mechanism, the cam lever 15 being returned, upon release, to its normal disengaged position by means of a spring I9.

The automatic'l atching means conslstsof a supporting block secured by screws 8! to the base plate Hand provided in its upper side with a T-slot 82 in which there is slidably engaged a locking bolt 99, the'nose end of whichis adapted to engage a locking recess 84in,the bearing standard 58, the bolt being normally pressed in projecting direction by means of a spring .85

through which connection the spring exertsprojecting pressure upon the bolt, so that when the recess 84 comes into register with the bolt as the slide' 51 is moved inwardly tl'Ye bolt automatically engages the recess and locks the worm in position. The lever 81 has secured upon one edge a bar 9| which projects outwardly to provide a handle for manually disengaging the bolt when desired. The inner end of the lever t? has an inclined face 81 disposed in the path-of the pin 50 carried by the worm gear, so that by adjusting the degree of projection of the pin the point where it engages the face 81 may be varied to thereby secure fine accuracy in the stopping point.

It willbe'under'stood that when the bolt is disengaged from the recess 84 the worm M will be withdrawn from engagement with the worm ring gear 45 through the outward pull of the springs 12 and I3, and such disengagement occurs automatically when the ring gear is rotated in clockwise direction to a point where the pin 59 engages the face 9! and through the swinging of the lever 91 withdraws the locking bolt, this action occurring at a predetermined point determined by theending of the winding operation. The bolt may also be manually withdrawn when geslred by means of the handle end of the bar As before pointed out the machine is primarily intended for the winding of wire or the like about a solid continuous core, and especially the'winding of wire about the ceramic ring or core of a rheostat, such ring or core'A and 'wire winding B being shown in Fig. 20. This ring is rotatably supported upon the post 26 and is clampingly connected to the worm ring gear 4550 that as the ring gear is rotated the ring A will be rotated with it. The support for the ring A consists, as shown in Figs. 4, 5, 14 and 15, of a circular piate slot 29 of the post 26, provided with an outwardly projecting peripheral, flange 94 spaced from the upper surface of the post 26, and provided adjacent its inner periphery with a platform portion 95 having a series of radially disposed bearing recesses 96 in whieh anti-friction rollers 91 are engaged and secured against longitudinal movement by means of set screws 98 engaged in an The upper surface of the. support 92 is provided with an annular recess lfll in which a guide roller of the clamping means moves, as will presently more fully appear.

In axial alignment with the shaft 23I and in spaced relation thereto there is secured in the bored end of the shaft I91 a driving shaft 236 upon which a clutch collar 231 is slidably connected by means of a spline 238, this clutch collar having clutch teeth 239 at one end opposed to the clutch teeth 235, and having a bore 240 which forms with the bore of the clutch member 234 a pocket in which is disposed a helical spring 24I which normally exerts pressure to separate the clutch teeth from each other.

The clutch collar 234 is provided with an annular groove 242 engaged by rollers 243--243 mounted in the yoke portion 244 of a clutch engaging and automatic throw out lever 245 which is pivotally mounted at its lower end by means of a shouldered'cap screw 246 upon a block portion 241 secured upon the base plate I2. Upon the block 241 a locking pawl 248 is pivotally mounted by means of a shouldered cap screw 249 and is provided at one end with a tapered locking tooth 250 adapted in the locked position to engage a tapered hole 25I provided in the lever 245, being held in engagement with this tapered hole by means of a spring 252 tied between a pin 253 provided upon the locking pin and a pin 254 provided upon the block 241,

The locking pawl is in the form of a bellcrank lever, and at its outer end is pivotally connected by means of a shouldered cap screw 255 to one end of a rod 256, which extends through a slot 251 in the vertical wall portion I4 of the base, see Figures 4 and 8, and is pivotally connected at its upwardly ofiset other end 258 to the slidable support of the worm 6|, this connection being preferably made by means of the pin 10 to which one end of the spring 12 is connected.

It will thus be seen that the shuttle driving clutch which is shown engaged in Figs. 10 to 13 will be automatically engaged upon manual engagement of the worm 6I with the gear 45 through the camming engagement of the tooth 250 with the slot 25 I and will be automatically disengaged upon either manual or automatic disengagement of the worm 6| from the worm ring gear 45, the forward movement of the worm support as the worm is disengaged pulling the rod 256 and causing the locking pawl 248 to turn and disengage its locking tooth 250 from the lever 245, whereupon the spring 24I presses the clutch collar 231 to the left, as seen in Figs. 10 and 12, and disengages the clutch teeth 239 from the clutch teeth 235,

thereby stopping the wire winding shuttle simul-' taneously with the stopping of the rotation of the ring-A.

-Between the drive shaft I96 of the variable power unit and the shaft 68 for driving the worm (ii the changeable gear means is provided for imparting power from the shaft I98 to the shaft 65, such gear means also being arranged to drive respooling mechanism mounted in relation thereto. The shaft I96 has keyed in its bored end one end of a shaft 259, the other end of which is journaled in a bearing standard 260 mounted upon the left hand edge of the base plate I3, a collar 26I being keyed upon the projecting end of the shaft adjacent the bearing standard. At an intermediate point the shaft 259 is journaled in a bearing standard 262 mounted upon the base plate I2, and between the standards 262 and 250 there are keyed upon the shaft 259 a bevel gear 263 and a spur gear 264, a spacing collar 265 being disposed between the spur gear 244 and the bearing standard 260.

The bevel gear 263 meshes with a bevel gear 266 keyed upon the end of an inclined shaft 261, journaled in spaced bearing portions 269 and 269 of a bearing standard 210 mounted upon the base plate I2, a worm 21I being secured upon the shaft 251 between the bearing portions 266 and 269, and a retaining collar 212 being secured upon the lower projected end of the shaft.

The worm 21I meshes with a worm gear 213 loosely mounted upon a shaft 214, and adapted to be connected thereto to drive it by slidable key means presently to be more fully described, the shaft being-journaled at one end in a bearing standard 215 mounted upon the base plate I2 and 7 at its other end in a bearing standard 218 mounted upon the left hand edge of the base plate l3, this end of the shaft having a projecting reduced diameter extremity 211, towhich is keyed one i member 218 of a universal joint driving connection, theother member 219 of which is slidably splined to the shaft 85.

The spur gear 284 meshes with a spur gear 288 also loosely mounted upon the shaft 284 and 8 adapted to be connected thereto to drive it by means of the sliding key, presently to be more fully described, this spur gear 288 having rigidly connected to it a spur gear 28| secured by pins 282, and the spurgear 28| having-rigidly con- 8 nected to it a smaller diameter spur gear 283 secured by pins 284, the gears-288, 28| and 283 adapted to rotate as a unit and the gears 28| and 283 adapted, as will hereinafter more fully appear, to drive the respooling mechanism. A spacing collar 2851s disposed upon the shaft 214 between the worm gear- 213 and the bearing standard 215. The portion of the shaft 214 extending from within the spur gear 288 to the end of the shaft journaled in the bearing standard 21s is provided with a cylindrical bore288 and there is a longitudinal slot 281 in the shaft extending the length of the bore and communicating with it.

A slide rod 288 is engaged in the bore 288 and has a projected key 289 secured in its end, which key engages the slot 281 and projects into engagement with a slot 290 in the hub of the gear 288, in one position, and in a slot 29| in the hub of the worm gear 213, in another position, it

' being understood that in these respective positions the spur gear 288 and the worm gear 213 are individually keyed to the shaft 214 to drive it, the other gear running idle. gne rod 288 projects through a passage 292 I0. provided in a plate 293 secured by screws 294 to the bearing standard 215 and it is provided upon its end with a hand wheel 295. A pair of spaced annulargrooves 298 and 291 are provided in'the rod 288, and one or the other of these'grooves,

[3 depending upon the position of adjustment of the key 289, is engaged by a pair-of yieldable retaining balls 288-298 disposed in passages 299-299 in the plate 293 and pressed toward the rod 288 by means of springs 380-308, and thus releas- 30 ably retain the rod in one or the other. of its operative positions. As will be clear from Fig. '1 the key is in engagement with the gear 288 when the rod 288 is in position to have the groovei298 engaged by the balls 299-499, and when the rod 55 is pulled out to engage the balls with the groove 291 the key is. in engagement with the. worm" gear 213. By this arrangement the worm 8| for driving the ring 45 may 'be' selectively driven, either by the worm gear-213 or the spur gear 280. 30 Upon the base plate |2, forwardly of the shaft 214 and the gears carried thereby, there is secured a bearingstandard 38l, in which is-journaled a spool winding shaft 382, this shaft having secured thereon a small diameter spur gear 55 888 in alignment with the large diameter spur gear "I and a large diameter spurgear 304 in alignment with the small diameter spur gear 283, the end of the shaft projecting beyond the hub of the gear 384 and being secured tothe spindle 70 888 of an automatic counting device 388 mounted upon the base plate l8, the counting device being for the purpose of keeping record of the number of turns of wire wound upon the spool.

spool winding-M882 is adapted to be 70 driven either by the gear "I or. the gear 233,

and for purpose a pair of clutch arms 381 and 808 are pivotally mounted uponstud shafts 309 and 3|8 projecting at each side of a bearing standard 3| I mounted upon the base I2. I The arm 381 has a spur gear 3|2 mounted thereon by 5 means of a shouldered cap screw 3| 3 and is adapted to mesh with the'spurgears 28| and-303 in its operative position, as shown in Fig. 8, while the arm 308 has a spur gear 3 mounted thereon by means of a shouldered cap screw 3|5, and is 10 adapted in the operative positionof the arm to mesh with the spur gears 283 and 384, it being understood that. only one of the arms is in operative position at one time. As shown in Fig. 8

the arm 381 is in operative position and the arm 1 308 is in inoperative position, the latter being dropped into engagement with the base plate l2 in this inoperative position and being raised from the base plate in the operative position.

Handles M8 and 3|1 are respectively provided 2 upon the forward ends of the arms 381 and 388, to. facilitate operating them and the arms are, respectively provided near their forward ends with holes 3| 8 and 3 I 9, with which a slidable locking bar 328, mounted in a block 32| secured to the bracket portion I8 of the base I2 is adapted to engage, this rod clearing the upper surface of the lowered arm 388 when it is engaged with the hole 3|8 of the arm, 381. The locking rod 328 is adapted to be secured in locked position by a set screw 322 provided in the block 32|. It will be understood. that, depending upon which pf the arms 381 and 388 is in operative position, the spool winding shaft will be driven by either one or the other of the gears 28| and 283.v

Upon the left hand end of the shaft 382 there is provided a spindle 323 upon which the spool I84 is engaged and retained by a collar 324, it

being understood that this spool can be respooled with wire while a similar spool; I84 is in operation 40 upon the shuttle I84, so that the respooling operation may be carried on simultaneously withthe winding of the ring A. Upon the forward surface of the bearing standard '38| there is provided an angle bracket 325,

which is hingedly mounted at itslower end by means of a hinge pin 326 having bearing in projectingbearing portions. 321321 formed upon the lower end of'the bearing standard 38|,' this bracket adapted to be secured in raised opera- 5 tive' position by means of a screw 328, engaged in the bearing standard 32| and extended through a vertical slot 329 in thevertical portion of the bracket, a wing-head 330 being provided at the outer end of the screw which is adapted to pass,

freely through the slot in its vertical position and I to lockingly engage the surface of the bracket in its horizontal position, so that by moving the screw to bring its head into the vertical position the bracket. may; when not in use,', be swungdownwardly out of the way;

Mounted upon thebracket m is a block :32

. having a T-slot- 888 therein in which'is slidably engaged a T-bar 334,- upon-theend of which is rotatably mounted a wire guide roller835; this roller being secured upon a removable pin 338 set in the end of a socket in the end of the bar 884 and secured by a s'etscrew 881, the roller beingretained upon'the pin by a headed screw 838. The bar 884 is provided with a handle 839 intermediate the ends of its upper surface, and

at its rearward end is provided with a stop plate 348 to limit the slidingmovement ofthe bar,.it

being understood thatthe bar may be slid back and forth for the purpose of positioning the guide roller 333 with respect to the particular spool be- .end with a retractable spring pressed pin 345 having a spring 341 mounted thereon between 35I is secured to the rearward side of the clampthe support 343 and a collar 348,,the end of the pin adapted to-engage the otherend of the bore 345 of the spool. A knurled head 349 is provided upon the end of the retractable pin 346 for the purpose of disengaging the pin from the spool to permit removal of the, spool and mounting of a new spool in .its place.

As shown in Figs. 1 to 5, and Figs. l4 and 15, the machine is arranged to wind wire upon a ring of relatively small diameter. However, the machine'is adapted by adjustment and interchangeability oi parts to the winding of a ring having a diameter substantially as large as the outside diameter .of the flange 28 of the post 26, and also to wind rings of any diameter between the small diameter ring as illustrated in Fig. 14 and the large diameter ring as illustrated in Fig. 18,

In Figs. 16 and 17 I have illustrated a replacement ring support 92 substantially similar in construction to the ring support 92 but of larger diameter, this support being suitable for the support of rings of sizes of an intermediate range of diameters between the minimum and maximum limits of the machine. This support 92', like the support 92, has a radial slot 93", a flange 94", a platform support 95 provided with radial roller recesses 96 and cylindrical rollers 31 rotatably .mounted therein and provided with conical rollers Hi0 at their inner ends. An annular recess IIlI is provided for engagement of the roller I 05* of the ring clamping block I03, this block being,pro-

vided at its inner end with a recess II I4 for engaging about the periphery of the ring support, and being provided at its inner end above the ring support withoutwardly projecting apertured flanges lin -I01 through which are slidably engaged horizontally movable clamping pins IOB I08, adapted to engage, the horizontal holes b of the'ring, the rearward ends of these pins being mounted in a' cross bar I03 movable in a slot I III of the block. n

The clamping head I I5 is secured to the upper. side of the block I03*'by .a set screw H5. The clamping head I I5 and its details are'similar to the clamping head I I5, except for slight variations in the dimensions, so 'that a further detail description of these parts is not deemed necessary. A vertically disposed. downwardly projecting square shank 35ll is secured to the block I03, this shank being in the same relative position with respect to the central vertical axis.of the support as the shank I25 of .the clamping member I03, so that when the ring support 32 is mounted in place upon the post 25- the shank 350 will engage the square hole 54 of the arm 52. A handle ing member Ill3 for manually rotating the rin to any desired position. v

vided at their inner ends with conical rollers I00". The ring clamping member I03" is provided with a recessed inner end I04 for engaging about the periphery of the ring support, and is provided at its inner end above the ring support vwith outwardly projecting apertured flanges N -I01 through which are slidably engaged the horizontally movable pins filt -I03 for en gaging the holes b of the ring, these pins being secured at their inner ends to a cross bar III!" slidable in a slot H0 0! the block I03". The clamping head 5 is secured to the upper side of the block I03 by a set screw H6, and except for slight variations in the dimensions is similar in detail to the clamping heads I I5 and I I5. The 1 block I03 is provided at its under side with a dependingsquare shank 352, also disposed in the same relative position with respect to the central axis of the support 92 as the shank I25 with respect to the axis of the central support 92, and is adapted to engage the square hole 54 of the arm 52. A handle 353 is secured to the rearward side of the clamping member I03 for manually rotating the ring to any desired position.

In the use of the ring supporting and clamping structures shown in Figs. 16 and 17, and 18 and 19, interchangeable replacement clamping arms I33 are mounted in place upon the support I29, these arms being relatively shorter than the clamping roller supporting shafts I31-I31 spaced wider apart, so as properly to engage the particular ring being wound. As these replacement clamping arms I33 are of the same structure as the clamping arm I33, shown in Fig. 4, except for length and width, theirillustration in the drawings is not deemed necessary for the clear understanding of the invention.

In arranging the machine for winding diflerent diameter wires it will be understood from the foregoing that the central vertical axis of the ring A being wound remains constant and is'coincident to the central axis of the post 26, but that the position of the body of the ring varies with respectto the central vertical axis, so that the wire winding shuttle must be shifted in order to bring its center into line with the center of the circumferential body of the ring. It is for this purpose that the block I5I. is mounted for sliding movement in the gibs 35-36. When the supports 32 and 92 replace the support 32 the slide block I5 I and the shuttle mechanism carried thereby, is simply moved rearwardly, being provided in its upper surface with three pockets 310, 3" and 312 in one of which a locking pin-313, disposed in a hole 314 in the cover plate 3|, is engaged to fix the position of adjustment of the slide'block NH. The universal joint connections 1 between the shaft I14 and the shaft 23I, as well as the extensibility of the connection provided by the splined slidable connection of the shaft I32 with the universal joint member I3I, permits the sliding adjustment of the slide block I5I without disturbing the driving relation. The same is true I support for the worm -GI and the shaft 314.

The operation of the machine is as follows:

The spool or bbbbin I8I, containing the wire suitable for the particularitype of ring to be wound, isplaced' upon the shuttle gear I54, the 70 spool having previously been wound by the spooling mechanism. The shuttle is rotated by means of the hand wheel) to a point where the slot lit registers with they slot I32 of the support Ill, and the ring A, and to which one end of the wire B, which has previously been carried about the tension and guide rollers, has been secured at one end by threading it into a suitable hole provided in the ring for this purpose. is placed upon the ring supporting member 32 by inserting it through the slots I08 and I82 so that the ring surrounds the shuttle.

' looked, as well as by connecting either the spur gear 280 or the worm 213 to the shaft 214 by shifting of thekey rod 280 by means of the handle 295. Also the desired tension for the particular wire is predetermined by adjustment of the calibrated tension dial I 88. The particular speed is-also predetermined prior to starting the machine, by engaging the clutch 202 with one or the other of the pulleys 201 and 208, it being understood that these preliminary adjustments are determined by the particular type of ringbeing wound and characteristics of the wire, a small gauge easily bendable wire being wound :vtr a different speed from a heavy relatively stifl' e. r The machine is then started by engaging the worm 8| with the worm ring gear by means of the hand lever 15, the shuttle driving clutch collar 23'! being simultaneously engaged by means of the tie-rod 258 which upon inward movement of the worm support is pushed to rotate the bell crank pawl lever 248 in clockwise direction. causing the tapered pawl tooth 250 to enter the slot 25I of the clutch operating lever and through the camming action between the tooth and the slot swinging the lever to clutch engaging position.

.of the lever '9 I The shuttle now rotates about the rotating ring winding the wire thereon, and this continues until the winding .is completed. At the predetermined winding completion point the pin 50 engages the arm 9| tripping the lever 81 and disengaging the locking bolt 83 from the recess 84',

whereupon the released worm gear support is drawn outwardly by means of the springs 12 and I3. Simultaneously therewith the shuttle driving clutch is released through the action of the tie-rod 256, the pull imparted thereto through the movement of the worm support rotating the bell-crank-pawl'lever 248 in clockwise direction vand disengaging its tooth 250 from the slot 25I', whereuponthe spring-2M forces the clutch collar' 23'! and its teeth 23! out of engagement with the clutch member 2 and its teeth 235.

The wire is then out between the ring and the spool, and the wound ring removed through the registering slots I86 and I62,-the holding arm' I33 having first been released and swung to its inoperative position upon the support I50. The

operator then pulls the clamping unit back to the starting place by means of the handle I28,

quently the pitch of the winding; by adjustment of the power unit, suchadju'stment beingshown on the dial 20L In winding larger diameter rings than that shown in Figs. 1 to l5 the. ring suppo t 92 and the clamping block I03 are replaced by the ring support32' and clamping block I03, as shown.

in Figs. 15 and 17, or by the ring support ring 02'' and the clamping block I03 as shown in Figs. 18 and 19, and the shuttle is shifted to bring its center into line with the circumferential center of the ring to be wound, the shiftable shuttle support being secured inits shifted position by engagement of; the locking pm 313 with-one or the other of the pockets 3' and 312.
