The taping device I Ilincludes a rotatably'driven' shuttleI I2 extendinga-round and mounted in a grooved annular bearing I 3; Said bearing isA 0'1"r 1 a substantially C-shaped formation with an open portion MQ tol permit an armature coil I 1`LA to be inserted -in theopen centerthereof.y Saidy shutg" tle is' likewise of a C-shaped`V formation'`1 ari-dis" provided withy an openportion- I5, to permit saidi armaturey coiltov be inserted therethrough land` said shuttle.

ffhebearing I3'is mountedin a frame I8; yliv'hil" is mounted'onthe -'-top1 of said pedestal on"y a plate I9.. A pair `of Vvertically spaced pulleys 2U, 20d

arev disposed at. thepf'orward endV of said frame,

x mounted' at the opposite vend of said frame on a. horizontal shaft 222'. l.Said shaft and pulley are driven Yfrom a motor 23., mounted on said plate, through a exible couplingZlI. 'lh'el outer periph--v eryofftlie shuttle VI'Zis gr'oovedy to receive a belt. drvngfifni thefdive pulley 21 and extending forwardly'froin saiddrive plley around the pulleys; 2n; zum and; than rearwardly' from said pulleysl around thegrooveformed in the outer periphery 0f sads'httl tdtaftably drivey said shuttle and leave thev open'ed thereof open in frame, to receive. an armature coil. I A tension A15111195? 7216; mounted Ori. van adjustably movable arim 2T, engages thev outer-side of' the upper run f the belt' 2,5`, for' maintaining said beltl atI the desired tension., ,n y

A s" Vol' orbobbin 29' is mounted onthe shuttle IZffor rotation therewith on a pin r3l). .Said bobbinis'adapted to pay'oif a'tape 3l", woundthereon; Said tp is` threaded from said bobbn bef tweenja tension spring 32' anda tension'plate 33, andinwardlyfromsaid tension plate tothe armature coil; whereitiswound thereon by rotation off said shuttle' andbottin with respect to the coilQ-in a direction which in Figure 1 shown as' being 'a clockwise direction.y A shouldered glid'e '35` is; provided in the' Central portion of'thh shuttle and; the-,other moving away from sarai shuttle* during" the' winding operation. Each of sani-hand rests has a fiat-upper portion 3i to" forni 'a rest l for I thel'hand and has .an upwardly spaced shouldered portion 39, against which the ation. The harid'restsv 35,536', as herein shown, are' each mounted ori the'upper ed of a` separate upright leg 40, whichl is'krount'ed andr projectsju'pwardly from' an internallythreaded sector of' a sleevel, forming a partial'nut engageablel with; the threads' of' a rct'atamy driven- `threac'ied shaft 443. Said legs extend through and are guided in guides 44, 44 formed in the top plate I9 and extending along said plate in a direction parallel to the axis of rotation of the shuttle I2.

The partial nut 4I is herein shown as being substantially a third of a nut so that during rotation of the threaded shaft 43, when there is no weight on the hand rest 36, the threads of said sleeve will come out of `mesh of the threads of said threaded shaft and said nut will remain stationary. When, however, the weight of the hand is placed on said hand rest, the threads of said nut will be engaged with the threads of said threaded shaft to cause said nut and hand rest to travel along said shaft, upon rotation thereof. Said hand rests may be connected in fixed spaced relation with respect to each other by means of a tie rod 42. Said tie rod may however be dispensed with where the lengths of the coils being taped differ, or where it is necessary to frequently adjust the spacing between the hand rests for different operators.

The drive from the motor 23 to the threaded shaft 43 includes a ipulley 45 on an end of a shaft 46. Said shaft is journaled intermediate its ends in a bracket 48 projecting from the frame I8, and has the lower pulley 26 secured to its end opposite said pulley 45, which serves to drive said shaft and said pulley 45. The pulley 45 is connected with a pulley 41 on a parallel shaft 49 by means of a drive belt 56. Said parallel shaft is journaled at its ends in a gear housing I, secured to the end of the plate I9 and forming a guard for change speed gearing for driving the threaded shaft 43 from the shaft 49 at a plurality of predetermined speeds.

Three gears 53, 54 and 55 are herein shown asl being cut integral with the parallel shaft 49. Either one of said gears is adapted to mesh with a gear 56 journaled on a shaft 51, which is mounted at its ends in a yoke 58 journaled on a hub In operation of the machine, the gear 56 is meshed with either of the gears 53, 54 or 55, depending upon the desired lap of the tape. The armature coil is then inserted through the open portion of the frame I8 and the open portions I4 and I5 of the shuttle I2 and bearing I3 respectively. The vertical edge of said armature coil is then engaged with the shouldered guide 35 and the shouldered guides 39, 39, said coil then being in a position so that the portion to be taped extends in the direction of the axis of rotation of the shuttle. The rnotor 23 is then started, the hands holding the coil in engage- 59 of a spur gear 66, on opposite sides of said gear. Said last mentioned spur gear extends within said yoke and is feathered on the shaft 43 for movement therealong, and is also meshed with and driven from the spur gear 56, which is journaled in said yoke.

Rectilinear movement of the yoke 58 and spur gear 60 along the shaft 43 will thus position the spur gear 56 to mesh with either one of the spur gears 53, 54 or 55, so the threaded shaft 43 may be driven at a plurality of predetermined speeds. Said yoke and spur gear are moved along said shaft by means of a hand lever 6I extending outwardly therefrom through a slot 62 forfmed in an end wall 63 of said gear housing. The upper portion of said slot is of a stepped formation to permit said yoke to be moved to a position to mesh the gear 56 with either of the gears 53, 54 or 55, or to permit said gear 56 to be moved out of mesh from all of said gears.

The means for locking the gear 56 in mesh with either of the gears 53, 54 or 55 is herein shown as being a spin and aperture lock including a plunger 64 slidably mounted in an upwardly projecting bracket 65 of the hand lever 6I. A spring 66 encircles said plunger and abuts the inner side of said bracket at one of its ends and a pin 61 at its opposite end. Said pin is mounted `in and extends through the plunger 64, so that when it is engaged by said spring said plunger will be urged in a direction to engage either one of a plurality of apertures 68, 69 or 16, corresponding with the positions when said gear 56 is isn5 mesh with either one of the gears 5354 or ment with the shouldered guides 39, 39 and resting on the hand rests 36, 36, to engage the secvtors'or partial. nuts 4I, 4I with the threads of the threaded shaft 43, so said shaft will move said hand rests with respect tosaid shuttle at a predetermined speed in the direction of the axis of rotation thereof.

Where it is desired that the leads or the legs of the coil be taped with a greater lap than the `slot portions thereof, the speed of rotation of the threaded shaft 43 is changed by meshing the gear 56 with the desired gear 53, 54 or 55. It should here be understood that while onlythree gears are herein shown, any number 0f gears may be provided which may be meshed with the gear 56 to provide the required feed of the armature coil, to give the desired lap of the tape thereon.

When it is desired to tape the knuckle of the coil, the hands are removed from the hand rests to stop rectilinear movement thereof and the coil may be turned `by hand to correspond to the intricate curve of the knuckle. When taping of the knuckle is completed, the hands may again be placed on said hand rests to tape the remainder of the coil lwith the desired lap.

While I have herein shown and described one form in which my invention may be embodied, it will be understood that the construction thereof and the arrangement of the various parts may be altered without departing from the spirit and scope thereof. Furthermore, I do not wish to be construed as limiting my invention to the specific embodiment-l llustrated, excepting as it -may be limited in the appended claims.
