2 Claims.

This invention relates to distributor mechanisms and more particularly .to a distributor for toroidal coil winding machines.

It is an object of the present invention to provide a simple, easily adjustable idistributor fora coil winding apparatus.

In accordance with one embodiment of the invention, a supporting clampcarrying a rectangular core with one side-of the core disposed within a winding ringof the toroidal winding apparatus may be recipro-cated by a distributor bar carrying a cam roller in the slot of .a slottedtcam member, pivotally mounted on a screwactuated plate, whereby the angle of the slotted cam member may be adjusted to predetermine the application of a winding on thecore.

A complete understanding of theinvention may be had by reference to the following detailedde scription of one embodiment thereof when considered in conjunction with the accompanying drawings, wherein Fig. l is a plan view of a portion of .a coil winding mechanism having a distributor connected thereto in accordance with the present invention;

Fig". 2 is a longitudinal sectional view taken substantially along the line 2-2 of Fig. 1 in the directio-nof the arrows; and

Fig. 3 is anendelevational view of the apparatus shown-in plan .in Fig. 1.

In the drawings, the apparatus is shown mounted upon a base 40 comprising a part ,of any suitable winding mechanism havingbearing brackets II and l2 mounted thereon-for rotatably supporting a :drive (shaft .13 and a winding ring l4 equipped with a suitable shuttle mechanism (not shown). Extending :upwardly ,from the bracket l2 are a pairof arms and 16, which support suitable guides for directing a strand from the winding ring 14 -.,to:a core III and also serve to support guide rollers I8 and IS, on which the winding ring is carried. Thelarm ,lfijof the bracket I2 serves as the bearing :for the-shaft-l3 on which a driving gear is supported with its teeth in mesh formed onthe inner annular surface of the windingring 14. Also mounted upon the shaft I3 is a drive pulley .2l, adapted to be driven by a belt 22, which may, in turn, be connected to any suitable driving mechanism .(not shown). In thismanner, rotation maybe imparted to the winding ring l4 to wind a serving of wire on the side of the core, which extends through the ring I4.

The right end of theshaft l3 hasjakhandwheel 23 fixed t it whereby rotation vmaybe imparted manually to the ring 14. Intermediatethe pulley 2| and the hand wheel 23, theishaft l3 carries a worm 24 in mesh with a worm gear 25, whichis freely rotatable about a, sleeve 26 encircling and keyed toa shaft r2'lby means f the key 28. A pair of bearings 29 and 30 support the sleeve 26,

member), which is slidably mounted in the ways the bearing .29 surrounding the sleeveat its larger portion, Which is provided with threads, as shown at .3] .A reduced portion .32 of the sleeve 26 extends into the bearing Bland the Shoulder formed at the junctureof the larger portion of the sleeve with the reduced portion 32 serving to hold the sleeve in the bearings. The rightendiFig. .2) of the sleeve 26 has a flange .33 formed on it which serves to retain the worm gear .25 in alignment with the worm 24, the fiange33 extending into a shoulder portion34surrounding the central aperture in the gear 25,. The right face ,of the gear 25, as shown in Fig. .2, is provided with clutch teeth 35-45. adapted to \COQDBITate with clutch teeth 3636 formed on a clutch member 31. The clutch member 3. is pin ed to t e shaft 2 10; means of a pin38 \(Fig. 1) and is provided with a pair of cooperatingshoulders'39 and 'fiflgbetween which an eccentric pin 4| extends. The pin 4| .is mounted eccentrically of [a stud shaftm42, ex-

tending through a side plate 143 and adapted to be,

manipulated by a handle .44 attached to it. Rotation of the stud shaft 42 by the handle 44 will cause the ,pin 4.! to move the clutch member 37 from the position shown, where a clutch member 45 on the left end (Fig. ,2) of the shaft2'l engages with clutch teeth 464,6 formed on the reduced portion 32 of the sleeve 26. When the handle 44 is manpiulated to shift the clutch member .31 from the position shown to its opposite position, the clutch member 45 will be-disengaged from the teeth 4646 and the clutch member 31wil1jbe meshed with the teeth l35,35 on the worm gear 25. The shaft 2! has a bevelled gear .41 attached to it, which ,meshes with a. companion bevelled gear 48 mounted ona manually operable shaft 49, which may berotatedby means of a handle 5!]. From the foregoing,itis'believed to be a parent that the sleeve .35 may be driven ,by. eitherlthe worm r 25 or y the h ft depend n 1 110 1 the position to which the shaft 2] isshifted, and

depending p Whe her clut h member 45 orclutch member W3] .is engaged ,with the gear 25 v or reduced portion ,32 of thesleeve 26, respectively.

The bearings 29 ,and 30 .are mounted upon a a 1ever65, carrying one endin alignment witha 'switchactuatin plun er '55 and t eotherendin the pathof a trave lin -nu 16 threaded z ngaeing the threads '3 .011 .the leeve .26. vT switch 63 is connected in circuit to the motor (not shown) and willibreakthernotor circuit when its plunger 66 is moved to theright (Fig. 2) due to the travelling nut 61 striking the lever 65 at the end of its travel to ;:the left (Fig.2). 'The travel .lingnut 6! is fixed to the underside pf a carriage H and 12 (Fig. 3). The ways H and 12 are formed in the side plate 43 and an intermediate plate 13, in which the carriage I9 is held by a keeper 14. The carriage T9 is cut away, as shown 'at 15, to slidably position a, slide member 16 for movement longitudinally and transversely of the carriage.

which is slidable in ways 18 and 19 and carries a core clamping plate 80 removably attached thereto by means of a thumb nut 8|.

From the foregoing, it is believed to be apparent that the core supporting block 1'! and core clamping plate 80 may be moved from the position shown in full lines (Fig. 1) to the position shown in dot and dash lines (Fig. l) to move the core I! from its full line to its dotted line position while a winding is being applied to the core from the winding ring l4 and that the reciprocation of the core supporting block 11 and its tcooperating clamping plate 80 may be effected by reciprocating the slide 16. In addition to the guiding means for the core supporting block H, the right end of the slide 16 is slidably mounted in a slot 82 cut in the side plate 43 and a slot 83 cut into way 13, and thus the slide t6 may be reciprocated with respect to the carriage 10 (Fig. 1) and the carriage 'Hlmay travel transversely of the direction of reciprocation of the slide.

The slide 16 carries a cam roller 90 extending from its upper surface and into a groove 9| of a cam member 92. The cam member 92 is pivot-.

ally mounted on the carriage 70 by means of a pivot pin 93 and is held in position with respect to the carriage by means of a retainer plate 9 which has a lip 95 extending over the upper surface of the cam member, the lip 95 being grooved to permit the cam member 92 to be suitablysecured to the upper surface of the cam L member 92. The shank of the screw 96 hasa knurled head portion I formed on it and is journalled in a' journal block I01, in which the screw is held by a pair of collars..l02 and lil3.

, A pivot pin I94 extending downwardly from the journal block HH extends into a bracket I05, which is fixed to the upper surface of the carriage member 10 and is bent upwardly out of the path of the cam member 92. Suitably fixed to the journal block llll is a scale plate I96 .for cooperation with a pointer I07, which is fixed to the block 91 in any suitable manner.

In the operation of the apparatus, the angle of application of windings on the core I! may be controlled by adjusting the position of the pointer I91 with respect to the scale plate I06, on which there are suitable lines scribed to indicate the adjusted position of the cam member 92. When the screw 96 is manipulated by means of the head portion I00, the cam member 92 will be displaced about the pivot pin 93, thereby to control the length of the path along which the cam roller 90 will be guided and, consequently, will determine the rate of movement of the slide 16. Since the slide 16 serves to actuate the core supporting block 11, the core will be moved an amount depending upon the angular position of the cam member 92 with respect to the carriage member 10. After a core I! has been suitably placed in position between the core supporting The slide member 16 is rigidly con-. nected to a core supporting block 1'! (Fig. 3),

block I! and the core clamping plate 80 and clamped therebetween with the travelling nut 61 in the position shown in Fig. 2, the handle 44 may be manipulated to move the eccentric pin 4| through an eccentric path, thereby to engage the clutch teeth 36 with the clutch teeth 35 and, by moving the shaft 21, to disengage the teeth 46 from the clutch member 45.

' position, the apparatus will be in condition to iii apply awinding from the winding ring M on the straight side of the core H, which i enclosed in the winding ring, and the motor (not shown) for driving the belt 22 may be started in operation to drive the shaft l3. As the shaft 13 rotates with the clutch member 31 in the posi-' tion opposite to that shown in Fig. 1, the worm 24 will drive the Worm gear 25, thereby to rotate the sleeve '26 and drive the travelling nut 61 to the left (Fig.2); This operation will continue and the strand from the winding ring M will be very accurately applied to the core I l as the travelling nut 61 moves to the left in timed relation to the rotation of the winding ring. This operation will continue until the travelling nut 61 strikes the lever 65 to operate the switch 63,

thus interrupting the operation of the motorafter stops, the strand wrapped on the core I! may.

be suitably secured thereto and after the core is removed from the apparatus, the clutch member 3'! may be moved to its inoperative position by manipulating a handle M. This will cause the clutch member to engage with the teeth 4-6 to condition the apparatu to be returned to normal position, as shown in Fig. 2, by manipulating the handle and rotating the shaft 49 in the proper direction.
