To all ALch-om 'if may concern.' y

rBe it known thatI, EUGENE Il. PHiLLIPs, a citizen lof the-United States, residing at East Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in 'Automatic Magnet-Winding Machines, of which the following is a full, clear, and exact description.

My invention relates to a machine for winding magnet spools, bobbi-ns, coils, resistances, and Vallsimilar windings where bare or insulatedwire is spirally applied to a supporting core or spool.

The principal object of the invention is to provide a machine of the general type set forth in my application No. 302,213, iled February 21, 1906, capable of winding the wire on its spool with smoothness and precision, and with sufficient speed to suit all commercial requirements. I further secure these purposes by a machine which is substantially automatic; not requiring any particular skill or difficult manipulation.

A further object of the invention is to construct a compact and simple machine, and which is adapted to receive spools of varying sizes and apply diderent grades and kinds of wire to form any desired shape or character of coil.

A still f urther object of the invention is to provide for a reverse of the winding motion for the. purpose of withdrawing the whole or a portion of the winding from a partly completed spool vat any time.

v-Wit-h these and other objects in view my invention consists in the construction, combination, location and arrangement of parts hereinafter set forth and shown, and finally particularly pointed out in the appended claims.

In the drawings, Figure 1 is a top or-plan view of the principal portion of a winding machine embodying the principles of my invention; Fig. 2 is a front elevation of the same; Fig. 3 is an end view looking from the right in Figs. l and 2; Fig. 4 is a detail view of the wire carrying head and guiding arm; Fig. 5 is a det-ail view of part of the reversing mechanism; Fig. 6 is a bottom view showing a largely diagrammatic representation of the spool and wire guiding arm; Fig. 7 is a side elevation showing the wire guiding and tensioning means which I employ; Fig. 8 is a front view ofthe same; Fig. 9 is a largely diagrammatic representation of theA driving and wire withdrawing mechanism. l

The application of metallic wires, whether bare or insulated,'in spiral windings upon a core presents special difficulties, and so far as I am aware, no machine has been constructed up to the present time which will wind wire upon spools of any except very short lengths Without requiring hand manipulation to properly reverse and direct the lead at the ends of the successive layers. The ditliculty occurs by reason of the hard and resilient nature of the Wire which cannot be forced to take an exact itch or lead as is the case with a softer or brous material. Fibrous materials like threads and yarns can be positively led with a predetermined feed, and the material packed closely into a smooth layer regardless of Whether the feed exactly corresponds to the diameter of the filament or not. Met-allie wire is, however, round and hard and resilient and will not pack together like brous material sothat if the layers are not led with their natural pitch, or, in other words, the feed suited to their diameters, and reversed at `precisely the right instant, the successive turns will pileup or become spread apart,

'either df which conditions injures the electrical properties, and mars the symmetry of the winding.

If the wire is led to a continuously rotating spool and progressively fed axially thereof as the spool rotates the wire will coilv itself about the spool, but whether or not this winding is in a smooth layer depends on having the proper tension in the vwire, and having a slight amount of rearward. inclination to the lead so that the wire will pack closely. If the tension varies or the direction of the lead is slightly changed, the resiliency of the wire comesv into play so that it winds more or less closely than before, and this variation, taken together with the slightly varying diameter of metallic Wires causes it to be almost impossible to make .two windings exactly the same. Accordingly the time at which the lead of the winding reaches the head of the spool cannot be exactly predetermined; it varying ywith the tension, with the direction of the lead, withA the resiliency and character of the wire, andirregularities in its insulation.

f This is the reason why ordinary spool winding machines cannot be used for winding `wire, since the reversal in a positive way,-

and at a predetermined point, cannot bearranged -to suit varying conditions which occur. cure the propei` reversal of the wire in spite of the difficulties mentioned.

The essential principle which I`make use lof consists in guiding the wire under proper conditions of lead, inclination and tension, with a positive and predetermined feed during the main portion of4 the layers, providing at the same time for slightly varying conditions due to different resiliency and diameter and tension of the wire; and then provide what I term a compensating reverse which makes the reverse of the layer at the head of the spool regardless of the movement of the positive feeding device at this time, and depending solely on the needs and requisites of the reversal itself.

Stated in more specific terms my invention consists in positively guiding the wire to the spool during the major portions of its length, and guiding it from a non-positive feed,w under proper conditions of tension and direction, at the-end of the successive layers. 4

Referring now tothe drawings, 1n which like parts are' designated by the same refer-- ence signs, l indicates the main frame of the machine upon a ortion of which are erected brackets 2 which serve to support a guiding rod 3. This rod serves as a guiding bed for a head stock 4 and tail stock 5 of the winding mechanism. The head stock f1 has a live spindle 6 therein, and is conveniently rigidly secured to the guiding rod 3 by a clamp nut 7.

8 designates the driving pulley upon 'the live spindle 6 by which it 1s. rotated from any suitable source of power'not shown.

The tail stock 5 is guided by a spline 9 upon the guiding rod 3, and may clamped in any relation thereon by clamp nut 10.

11 designates the tail stock spindle. Both the live stock spindle 6 and the tail stock spindle l1 are provided with chucks 12, between which a spool or core'may be clamped for the purpose of winding.

Parallel -to the axes of the winding spindles above described I arrange a screwl shaft 13 rotating in fixed bearings 14 and having a hand wheel 15 at one end and a gear 16 at the. other. The gear 16 meshes with a train of gearing by which motion is communicated to the screw shaft 13 from the live Theessential characteristic of the wirev guiding mechanism is the combination of the-'positive means for guiding the Wire In carrying out my invention I se-' memos `along the major part of the spool with the compensating reverse made by the movement of the wire itself. Referring particularly to Fig. 4t, I have illustrated a practical form of wire guiding mechanism comprising a travelinghead 17 which has an opening 1S internally threaded so as to engage the threaded shaft or lead screw 13. The traveling head 17 is additionallyguided by an extension 1:9 having an eye 20 which incloses' the longitudinal rod 2l. Upon the forward side of the head l'are pair of projecting ears\22, which serve to guide the vertical threaded pin 23 having a spline 24 so as to be non-rotatable therein.

25 indicates a thumb nut engaging the threads upon the pin 23 sons to vertically adjust and maintain it at any desired verti-V cal elevation.

The threaded rod Vor shaft 23 has secured thereto the wire carrying frame 26 which embodies standards 2G with a large guiding wheel 27 thereon,and also a depending part or sub-frame 2 6, which is also rigid with the frame 2G. Guided by the vertical axis 28 upon the frame 26 is a swinging arm 29 which I conveniently make in the triangular form shown in order to secure greater ystrength consistent vwith lightness,

30,31 and 32 designate guiding wheels or rollers each having a grooved periphery for leading the wire into winding relation.

33 indicates a wire lock or holder for securing the free end of the wire between operations, and which may be formed' of a pair of spring pressed disks similar to the ordinary tensioning means for sewing machines.

The various wheels 30, 31 and 32, and the 1 lock or holder 33 are all carried by the swinging "arm 29 in any relation, but preferably in that shown. in which the inner edge of the guiding wheel 30 is substantially in alinement with the vertical axis of the arm, sothat the wire guided thereby from the wheel 27 will always be led to such wheel in a true tangential plane. The final or terminal guiding wheel 32 is carried in proximity to the winding spindle, and in aspecial` relation therewith, as diagrammatically indicated in Figs. 4, 6 and 9. As Seen from these figures the l-wire passes from the final or delivery roller 32 upward and slightly forward toward the tangential surface of the usual spool to be wound, which inclination is preserved or increased as the winding progresses. In this way a radial component of force is outwardly exerted upon the wire'guiding arm by the tension of the wire itself, tending to hold the arm 'in its normal or perpendicular relation. but

Aby the requisitesof the feed, or other reason.

The swinging guide arm 29 oscillates izo " freely on its axis 28, except so far as oondash pot 34 upon the sub-frame 26".

5 trolled by the Atensionof the wire as above described,- and a resistance appliance pr n practice I make use of a cylindrical cup 35 filled with oil or a viscous fluid and having wings 36 therein extending from, aA central stem 37. The stem 37 is geared to a segment 38 co-axial with the axis 28 so that the motions of the swinging guide arm 29 are transmitted to the stem 37 and wings 36, and the impedance due to the viscous Huid exerts a certain light resistance to the movements of the swinging guide arm.

I will now describe the connections by which` the wire guiding head 17 is impelled in its to and fro movement upon the lead screw 13.

The live spindle 6 carries a pinion 39 which meshes with a large gear 40 on a countershaft 41, which in turn carries upon.

its other end a change gear 42. The change v'gear 42 meshes with an idler 43 on an adjustable parallel shaft 44, which in turn is in mesh with a gear 45, also-journaled at 46 upon the frame of the machine. The shaft 46 carries loosely mounted upo-n it the gears 47 and 48, which may be of different diameters, and which respectively operate lthe Vgears 16 and 49 both rigidly fixed upon the lead screw shaft 13. The gear 49 is directly in mesh with gear 48, while the gear 16 is driven from the'gear 47 by an'intermediate idler 50, so that its rotation is in the opposite or reverse direction therefrom when clutched into actionl"v y The ipitchratios are fixed at such values' as to produce the same speed of the lead screw in its reverse as in itsforward movement..

51 indicates assleeve splined to the shaft 46 so as tobe capable of independent. longitudinal movement, and the ends of this sleeve are toothed or crowned, as shown at 52 and 53, so as to engage corresponding teeth or crowns 52 and -53 upon the gears.

47 and 48. By this arrangement the sleeve 51 may be moved so that its teeth engage one or another of the gears .47, `48, whereupon such gear' will be clutched to the sleeve and will rotate with the supporting shaft 46. 54 indicates a collar surrounding the sleeve by which 'it is longitudinally moved.

I provide means for shifting the collar 54 and sleeve 51 so as to t-hrow either of the gears 47 or 48 into operation to. drive the lead screw in one direction or the other. In practice I have found that a hand reverse is ordinarily sufficient by reasonof the com.-

pensating action of the swinging arm wire.

guide which I employ as 'above described. A convenient form of hand reverse is particularly illustrated in Fig. 5, although it is to be understood that this is merelyan 4eX- emplary practical construction and any other hand or automatic reverse could be' used in lieu thereof. 55 indicates an arm or a lever connected to the clutch collar 54, by means of which the clutch sleeve can be shifted longitudinally so as to engage the teeth 52 and53. 56 denotes what I shall term a shifting and locking block, and

supports, so that the block 56 is capable of reciprocating longitudinally. 59 and 60 denote pinshaving a vertical movement with- -in their containing'- frame 61. The lower ends of the pins 59 and 60 Vare formed with a squarepoint or shoulder 59 and 60, which respectively contact with and move upon the inclined cam surfaces 57 and 58. Each of the pins also has a vertical diametral slot therethrough, indicated at 62, and a. notched bar 63, guided by the frame 61 extends through both of the slots 62, as clearly shown in Fig. 5. The upper and, lower parts of the slots 62 within the pins have V-shaped-shoulders'as shown at 64, and the notches 65 of the bar 63 are formed vto coperate with the Vshaped shoulders of the pins, sothat one pin is-moved downward Vand positively locked in such position, while the other pin is moved upward and positively locked in said upward relation. When the transversely moving bar 63 is shiftedto .its other position, as, for example, to the right in Fig. 5, the pin 59 will be positively cammed upward and the pin 60 positively cammed downward, and both pins again locked in the new relation. The effect of this movement of the pins 59l and 60 is to throw the shifting and locking block 56 to and fro by the camming action of theshoulders 59 and 60 against the in clined walls 57 and 58. v.It is evident that the block is held at either'extremeposition, as, for example, in its right-handA position in the figure, by the continued opposed engagement of said shoulders and cam walls. 66 denotes a. momentum lever which may be pivoted at`67 upon the shifting -bar 63. and guided to oscillate when the bar is reciprocated, for the purpose of insuring a full 'throw of the lever.

The shifting` bar 63 is moved to and fro by the -lever 67a, (Fig. 1) having a link connection 67b therewith. lThe handle 67 of this lever projects upwardly into convenient reach of the operator. 1n case the machine is arranged for hand reverse. If the Amachine is made fo-r automatic reverse, thel automatic devices would, of course. bc substituted for the lever 67a. By the above mechanism it will be understood that the operator is ablel to eiiect an almost instantaneous reverse of the movement of the lead screw whenever her judgment determines that the layer has progressed suiiciently far to warrant it. On account lof the high speed of the winding operation, and the nature of metallic wires. as above indicated, the reverse of the lead screw willoccur an indefinite distance, varying anywhere from one to a'dozen turns before the layer actually reaches the spool head, but the actual point of the lead screw reverse is immaterial on account of the compensating action of my wire guided swinging arm reverse, the operation of which will be hereinafter more fully stated.

The essential feature of the leadscrew reverse is that it should be sudden, complete and locked in either thrown relation, and it is evident that the practical construction of reversing mechanism which I have described, accomplishes all of these purposes.

l/Vz're supplying and tensioning mea/ns." Inv addition to the mechanism for directly leading the wire upon the spool, I provide means for supplying it under proper tension, the nature of which is particularly indicated in Figs. 7 and 8. 68 designates t-he supply reel, which is the ordinary wooden reel, upon which Acopper wire is furnished by the manufacturers. This is supported by standards 69. 70 denotes an additional standard, having a rigid plate 71 at its upper end, from which depend stretched wires 7 2, which serve to guide a vertically movable carriage 7 3, carrying a pulley 74. 75 indicates a long tension -spring attached to the plate 71 and to the carriage 73, so as to normally press the carriage upward. 76 indicates another standard, carrying the pulleys 77 and 78 in planes to guide the wire from the pulley 74 to a small guide pulley 79 upon the traveling head 17 of the winding machine proper. The relation of the pulleys 78 and 79 is such that the direction of the wire from one to the other-coincides with thedirection of movement of the wire carrying frame. From pulley 79 the wire passes upward and over the largel grooved wheel 27 above referred to. The wire, designated as IV, is initially led from thereel 68 over the tension pulley 711 and the various remaining pulleys 77, 78 and 79 to the winding mechanism. The reel 68 has process. For example, the to and fro inotions of the wire carrying frame tend to slightly vary the length of wire between the reel and spool, but .this slight variation is compensated for by the movements of the carriage 78.

ill/cams fm' fivzt/LfZ/rafwayor tmwindz'ng 157m wir@ from a partly completed sp0oZ.-Referring to Fig. 9, I have illustrated diagrammatically the essential features of the wire withdrawing or rewinding'mechanism which I employ in practice. :The reel 68 and the spool A. to be wound are indicated in substantially the relative positions they occupy lin practice, and the course of the wire is generally indicated by the line W.. The conical friction member 80 is shown inserted into the reel 68 so as to give the .cone 8O and connected by a belt 82 with a similar pulley 88 on a sleeve 84, forming part of a clutch Vloose on the driving shaftSG. 87 denotes a similar clutch member on a sleeve 88 having a'pulley 89, belted at 90 to the driving pulley 8, previously mentioned, on the winding spindle. 91 indicates a sleeve splined to the driving shaft 8G and adapted to be thrown into frictional engagement with the clutch members 85 or 87 by a treadle mechanism, designated as 92. It will be obvious that when the treadle is depressed to clutch the member 87 to .the

driving shaft, that-the winding spindle is' rotated to apply the winding, but that when the treadle is moved to clutch the member 85 tothe driving shaft, that the reel 68 is driven reversely, so that the wire is rewound thereon and withdrawn from the partially completed spool A which is4 capable of revolving idly for such purpose. The particular features of the clutches and belting arrangements, as above outlined, and illustrated in Fig. 9, are, of course, largely diagrammatic, merely serving to illustrate the essential features of 'the two clutches which can be frict-ionally engaged to drive the pulley, or reversely drive the wire containing reel, underthe motions of a treadle. In practice the practical details will be considerably modified, as will be obvious to any mechanic skilled in the art.

From the above description the operation of the wire guiding, tensioning, withdraw-- ing and lead screw reversing means will be sufficiently understood. These features while practically important are susceptible of being worked out in different ways, and I I regard them as of inferior significance in relation to the features of the compensating swinging arm reversely guided by the wire itself to reverse .the layers at the heads of the spools. I will now take up in detail the action of 'this important feature.

The' operation of the compensating layer .Y reverse is as follows: Referring particularly to Fig. 6, which shows a bottom view,

diagrammatically represented, the spool A is continuously rotated in the direction of the arrow1 and the wire passes from the guiding aim 29 on to the spool in a helical1 winding which feeds toward the right by virtue of the motion of the lead screw. It will be seen that the arm 29 has a force applied to it'tending to maintain it in the perpendicular relation shown, on account of the tension of the wire itself, which exerts a radial component on the arm at its outer end. This force, together with that of the dash pot, is enough to keep the arm`inrigid .y relation under ordinary circumstances, so thatthe wire is applied to the spool with a pitch corresponding to that of the lead screw. If by reason of a slightly changed diameter in the wire, or uneven resiliency, or other reasons, a coarser feed should be required, -the swinging arm 29 can move ahead slightly with respect to the lead screw, so that the wire is not piled up on account of the positive feed of the lead screw. During this action themachine is operating very rapidly and as the layer approaches the head C of qthe spool, the'mechanism is actuated which reverses the motion of the lead screw. As-above stated, I employ .either hand or automatic means for effecting this reverse, but in practice it is ordinarily sufiicient 4to make use of the hand reverse since the operator, who is'necessa'rily pres-` out any special mechanism for the purpose.t

This is the more true on account of the difficulty of effecting a prearranged automatic reverse at the proper inst-ant required with respect to the condition of the layer. In any case, whether the reverse is made auto'- matically or by hand, it is made preferably a number of'turns before the lead of the wire has reached the head of the spool. On account of the high velocity of the rot-ation it is diicult, if not impossible, to secure the reversal of the screw at the particular turn or portion of a turn required, by either automatic or hand devices. The reverse of the positive feed is, in lmy invention, madeI to occur before the winding reaches the head.I

' so that the direction of the lead is slightly modified and tends to cause a reverse of the wind. When the head of the spool is .movement applies or sition on account of the radial componentof force upon the arm due to the tension of the wire. If, however, the resiliency and character of the wire requires momentarily a different .feed from that of the positive lead screw, the swinging arm is always able to accommodate the particular need. When the lead approaches the other head of the spool, the operator, or the automatic devices, el'ect a reverse as in the previous instance, and the swinging arm continuing its whips the wire toward the head of the spool and back again, making. a smooth, precise and .perfectly contiuous winding, meeting all required practical conditions.

Adjustments-I provide all necessary adjustments by which the machine is adapted to receivev spools of different sizes and dimensions,to wind them with different sizes of wires, and to ygive the different turns' varying feeds or pitch. I have referred to the adjustment of the head stock 4 and tail stock 5 by which they may receive different 100 size spools. The gears 42, 43 and 45 are change gears, and may be varied to secure any desired speed or pitch. For this pur-l pose the gear 43 is mounted in a slotted bearing in the usual manner of change gears. The vertical height of the wire carrying frame is adjustable by the nut 25 to suit'different sizes of spools and differentkinds of wire. It is evident that the separation of the guide wheel 32 from the spool would be 110 greater in the case of large wires than small ones. If necessary the wire guiding frame may be made adjustable forwardly and back so as to adjust the inclination 'of the lead for different diameters of spools. It is evident that other adjustmentsmay be p'rovided, and I desire to include within my invention any ordinary adjustment of the various parts. I
