'10 ments in'ma'chinfes for applying tape to armature coils, and its object is to facilitate the operation of applying tape to the coils preparatory to placing the coils in the grooves of thejarm'ature core or body. 15 Ifhe present invention relates more particularly'. to'the winding of that typeof armature coils which are first wound upon a' suit-- able form and their the strands are boundt o- X gether by awinding of tape and the coils thus 2 completed are ultimately placed. in the grooves formed in the armature core for the purpose of receiving the coil.

By the present invention any desired degree of tension of-the' tape upon the strands 2 may be obtained, since the winding is entirely mechanical, and the operator has but to. ad-

vance the coil slowly" through the machine v to insure the progressive covering of the strands. I Provision is made by the present invention for the ready insertion in and removal of the formed coils from the winding structure, and theoperator may readily 'redet'errnine the 7 degree of tension to be applied to the windin' tape, so that the strands of the coil are boun together firmly and without danger of subsequent displacement in the operation of the'armature.

The invention will be best understood 0. from a consideration of the following detailed description, taken in connection with the accompanying'drawings, forming a part of this spec fication, in Whlch drawings-- Figure 1 is a side elevation of the winding 4 machine. Fig. 2 is a plan view of the same fivith 'a' portion 'br'okenj awa Fig. 3 1s a radial section through the ring for'sup ortin' a reel for binding ta 9, said section libing ta en through the rec in vthe plane of the axis of rotation ofsthe ring. Fig. 4 is a view at right angles to that of Rig; 1, 'of thetemv sion device forthe tape. Fig." 5 isa detail view showing the meeting ends of the ring and gate therein in perspective. A

Referring to the drawings, there is shown a suitable base 1, nearone'end of which is driven by the shaft 13, receiving motion 1 formed a pair of parallel guides 2. These guides are undercut to receive a' block" 3, on which is erected two pedestals '4', re ceivin the journal 5 of a flanged roller 6x The block 3 is adjustable in the-"gu des 2 to di'fierent positions by means "of athumb or set screw 7, arranged to enga e'in any one ofa number of sockets Sin theuse 1','bj tween the guides 2. By this means the "block 3'may 5 beheld in any one/of s'everal'adjus'ted'i ositions for a purpose which wilt'presentl appear. On each side of the guide; 2 the base 1 is provided with aseries' of sockets oiperforations 9, into any one'of which niay fit the bottom end of a 0st 10., aIideach'pbstQthei e' being one on 'eac side of the gliides'l isiprovided at its" upper or freeen' "with a notch or recess 11, the purpose of which wi'llpresentlj appear. At'the end'ofthebase ;'remote fronithe guides 2 there are other ede'stals 12,"for ned with journal barin s on shaft 13, carrying near-one end rpu ley' 14 and near the other end agroovedroller 15. The pulley 1.4 receives power froma'ny su'ifable source as b Rmeansof abelt 161 Mounted on t e base 1 below the grooved 1 or flanged roller'15is thelbwer' endflof'a' spring --armi1'7 rising from the 'base'l andoverhanging the flangedrolle'r' lSa'n'd "ex- I tending a distance toward "the" guides 2.

Thenprper free end of the arm 17 carries jour-. nal bearings 18for' the journal 19 of aflanged roller 20; The several parts'are so arranged that the flanged roller 6,- the flanged roller :15, 90.

and the flanged roller 20 are'all'inthesa ne vertical planecutting the axes of the several rollers'at'right angles.

' Mounted upon and supported by-the sev-.-

eral flanged rollers 6'," 15 and '20; is'a ring 21, rotatably supported by the 'several rollers and receivingrotativef novement by its en. gagement with the roller 15, which latter is from the power pulley 1 4 fastened 't ere'on. The several parts so far described ma all be made of metal with the exception 6 the flan ed roller 15, which may be made in who e or in part of fiber or other suit-able'mae terial, orits bearing face may be forniedof fiber, so as to readily grip-the peripher ofthe ring 21 and impart rotative move'nien there-. to, even when the rotative movement of the ring 21 is subjected to more 'or less resistance. I

Projecting radially inward from the inner face of the ring- 21 is a-lug 22, the extent of projection of the said lug in an :mwarddirection being considerably less than the radius of the said ring 21. The inner end of the lug 22 is tapped to receive the threaded end of a thumb-screw 23, carrying a sleeve 24 between two dished washers or plates 25,

theksaid sleeve 24 and plates or washers 25 an arm 29, made fast by a screw or othera notch 36.

wise to a lug 31, formed at an appropriate point on the inner edge of the ring 21. The

spring 29 is extended beyond the screw 30 and bent away from the lug 31 as shown at 32, and there is engaged by the head of an adjusting screw 33, entering a suitably tapped hole in the ,lug 31. The thumb or adjusting screw 33 serves to rock the spring 29 about its securing screw 30,'to bring the freeend of thearm 29 with greater or less force against the lip 27.

The ring 21 is provided with a hinged sec tion 34, the free end of which is formed with a tongue 35 having at about its central point The matching end of the ring-21 where the free end of the hinged section 34. engages it, is formed with a corresponding recess 37, having a .centralpin or web 38, which enters the notch 36 when the tongue 35 is seated in the recess 37. The ring 21 is slightly elastic so that it may be expanded sufliciently to permit the introduction in or removal of the tongue 35 from the recess 37. This is found in practice to be an ample latch mechanism for the hinged section 34, but it is within the scope of the invention to use any other suitable latch mechanism for holding the hinged section 34 into coincidence with the ring 21, or for permitting the removalof'the free end'of the said section. 34

from engagement with the main body of the ring 21, so that the section 34 may be moved about its hinge.

There is indicated at 39, in dotted lines, an armature windin This indication is to be taken simply as illustrative, and not in any manner as showing the size or shape of the armature windings, as these windings vary greatly both in shape and size. Let it be assumed, for purposes of illustration, that the armature winding 39 consists of a number of turns of a single strand of wire suitably insulated and suitably shaped, and that it is desired to wind tape upon this winding, in order that the strands may be firmly bound together and also the winding as a whole be insulated from the walls of the grooves of the armature core provided l'or the reception ol' the arnmturewinding;

Preparatory to winding the armature coils with ta e a suitable roll of tape shown in dotted ines at 40 is applied to the spool formed of the sleeve 24 and the plates or washers 25, this being accomplished by the removal of the thumb-screw 23, which allows the disassembling ol' the spool for the purpose of applying the tape. The end of the tape is now carried around the finger 28 and under the lip 27 so as to be engaged by 5 the freeend of the spring arm 29. The armature winding 39 is now introduced into the rin 21 throu h the hiiwedsection 34,

and is permitted to rest in the recesses 11 111 the upper ends of the posts 10. The free end so of the tape 40 is now wound around the armature coil by hand for a turn or two 'until firmly united thereto, such tape being usually of a more or less adhesive nature, so

as to readily. unite with the strands of the coil. Power is now applied to the pulley 14 by means of the bolt 16, or directly by any source of power, the belt and pulley being simply used as an illustration of any suitable source of powerior imparting rotative movement to the flanged roller 15'. Suppose that the movement of the pulley 14 be clockwise then the movement of the ring 21 will be counter clockwise. Now the tape will be slowly wound upon the coil 39 by the continned rotation of the ring and the tape will be slowly withdrawn from the roll of tape upon the spool carried by the thumb screw 23, the tension of theta e about the coil 39 being determined by the pressure of the spring arm 29 upon the tape against the lip 27, and the said tape being guided from the s 001 about the finger thence over the inc ined edge and finally between thelip and the spring arm 29, before passing to the coil 39. As'the winding progresses the coil 39 is slowly moved in the seat formed by the recesses 11 at the upper ends of the posts 10, so as to cause the tape to be helically wound upon the strands of the coil 39. The movement of the coil 39 to cause the progressive winding of the tape thereon is performed by anoperator and requires practically no skill. The winding of the tape upon the coil may progress until the entire coil is covered with tape, when the machine may be stopped and the tape out, and then by opening the gate 34, the completed coil may be readilyremoved from the interior of the ring 21. The unwinding of the ta e from the reel supporting the same may e determined by the tension of the thumb screw 23 and the dished plates or washers 25 brought by the thumb screw into engagement with the sides 01 the reel of tape.

In practice it is found that for diiierent sizes of ari'nature coils and for different widths of tape, it is advantageous to have dill'erent sized rings 21. In order to accom- Inodate rings of different size is the purpose By this means the structure is made to 'ac-' commodate at least three rings 21 of different sizes. The spring arm 17 provides means for the ready removal or insertion of I the rings 21 in the several flanged rollers, since it is only necessary to lift the roller 26 away from the ring 21 when the latter may be readily removed from engagement with.

the other two rollers. c It is to be observed that the machine is adapted for winding tape upon armature COllS already formed, whether of the open or i closed type. ith the closed type of -coils, the gate 34 is necessary, but with the open type of coil, if used exclusively, the gate need not be provided. In order that the winding oi the t: )e upon the coils may be best performed t e portion of the coils being wound should be substantially in the axis of rotation of the ring 21, and for this reason the posts 10 are made adjustable in the sockets 9 when rings 21 of different sizes are used. Furthermore, the interior of the ring 21 should be quite free and unobstructed, so that ample space is provided for winding the corners of the coils which usually are of rectangular shape, and for accommodating the sides and ends of the coils when they are of the distorted rectangular shape.

It is to be observed that the axis of the tape carrying spool is radial to the axis of the annulus or ring 21. This ermits the spool to be brought into quite c ose relation with the inner periphery of the annulus and still brings the tape into proper relation to the tension means.

It is possible to mount the machine upon a table of suitable height and apply power through -a pedal actuated by theoperator.

=Also, for different sized rings, other s ring arms 17 may be used so as to always ring the roller 20 over the axis of the ring 21 or the arm may be mounted in guides like the guides 2. Furthermore, instead of driving the ring 21 frictionally by the roller 15, any suitable form of positive drive may be used. or instance the roller and, rin may be pro vided with gear teeth, especially when rings without the gates are used, although it is possible to use gear or other like driving means even with rings provided-with gates.
