COTE- IN Application filed iiovemher it, 1920.

To aZZ whom it may concern Be it known that l, Jase-an T CULLIN, a citizen of the United States, and residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and -l'mproved Coil-Winder, of which the following is a specification.

This invention relates to means for winding wire coils, particularly for electric motors and generators, and is of the same general type as that shown in my prior application Serial Number 407,708, filed September 2, 19.20, and its object is to provide meanstor simultaneously shearing free the two ends of the just previously wound coil and securing the end of the supply wire to a part ottlthe winder for the winding of the next (301 I This invention consists in combination with a winder for coils comprising two members, one having a rectangular hub with inclined edges and the other member being adapted to fit against and be secured to the first to cause the strands at the ends of the coil to keep their proper positions, of a shaft on which the winder is mounted, a plate on the shaft adjacent the winder and having a plurality of fingers, and shear members mounted on the plate and adapted to co-act with the fingers to shear the ends of the coil.

llt further consists in so positioning the shear membe'rsand the fingersthat the shear member which cuts the coil from the supply wire also bends the end of the supply wire around one of the fingers so that the wire may be drawn from the supply when the winder is rotated.

lit also consists in so positioning another shear member that when the coil is com pleted this shear memberwill cut ed the bent over end of the wire.

lit also consists in the detailsofconstruc tion illustrated in the accompanying drawings and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of this improved coil winder. Fig. 2 is a similar plan with the shearing means at the ends oi the cutting strokes. Fig. 3 is a section on the line 3-3 as Fig. 1. Fig. t is an end view talren from the left in Fig. 1. Fig; 5 is a plan otthe winding head and shear. Fig. 6 is a section on the line G t ot Specification bf Letters Patent.

Similar reference characters refer to like parts throughout the several views.

Any desired means may be employed to support the spindle 1 and to rotate it the desired number of times to cause it towind a coll, as explained in my former applicatlon. The outer end 2 of this spindle is preferably enlarged and on it is slidable a sleeve 3 having a groove 4 and a conical outer end 5. A lever 6 pivoted at 7 has a pair of arms 8 provided with pins 9 that extend into the groove l and by means of which the sleeve may be moved back and forth along the shaft.

A collar 10 and plate 11 are mounted on the outer end of the spindle and from the main portion of the plate extend the three fingers 13, 1d: and 15 which carry the pivot 16 on which the shear levers A and B are mounted. The fingers l4: and 15 are similar, being provided with inclined faces 17 leading to the shear edges 18 onthese fingers. The upper end 21 of the upper arm 22 of the lever A has a notch 23 to receive the supply wir 20 from which the coil is wound, and when this lever is swung from the position shown in Fig. 1 to that shown in Fig. 2, shears this wire in cooperation with the edge 18 of the finger 14. The forwardly extending upper end 24 of the upper arm 25 of the shear lever B cooperates with the shearing edge 19 of the finger 15 to shear another portion of the wire at the same time as the shear lever A is operating. The rear or

lower ends

26 and 27 of these levers are connected by the block 28 and the bolt 29. The end of the arm 27 is rounded to engage the conical end 5 of the sleeve 3. An outward movement of this sleeve will swing the cuttingedge of these levers across the shear ed es of the fingers 14: and 15. v

' ounted on the outer end of the spindle is a winder plate 30 and a central pin 31 onto which a follower plate 32 maybe locked by means of a latch 33 after being positioned by the dowel-pins 34. The pin 81 has a groove 35 to receive the latch. The follower plate has a rectangular hub 3'? and oppositely extending radial ribs 38, the edges of the hub being beveled as shown in Figs. 1 and 2.

A finished coil-39 is shown on the winder in Fig. and a clipetl is shown holding the wraps together so that they will not uncoil when released. The lever 6 is then swung llll 29 is started rotating. ;The supply wire 20 to the position shown in Fig. 2, which causes the upper end 2l of the shear member A to. sever the end 42 of finished coil, which end immediately falls, and the upper end 24 of: the shear member B to sever the supply wire 20 at 43, which permits the end 41 to spring out as indicated in Fig. 4. It

, will be noticed in Fig. 4' that there isa space between theside of the end 24 of the lever B and' up'per end of the adjacent finger I 14. 'Whenthis end of the lever'is swung forward, it bends theend 44 (Fig. 5)] of thesupply wire into this space and around the finger 14.

The latch 33 is then swung (to the right in Fig. 4) to release the 'p1n 31,"andthe follower plate andthe. finishedcoil there- 'on is lifted off the in 31 to permit the finished coil to fall. efol'lower is immediately replaced and locked. and the shaft 1 swings down (relatively)*along the front ed e of the finger 13 and is carried by the inc ined edge 45 thereof'to the space b'etweenthe plates'30 and "32"of the winder wherein the wire'is wound thedesired'num ber of wraps, passing in front of the fin ers 14 and v15 while being thus wound. net

before the winder stops, the operator guides th'e'wire into the notches in the ends of thefingers into the path of the shear member 24, as shown'in Fig. 4.

The shear members are returned by the coilspring 46 which extends around the collar'lO and has its ends hooked around the parts. 26 and 27 of the shear members, being held in osition by the pin 47 The operator therefore has only to swing the lever 6, remove the plate 32 and replace. it, start the shaft rotating, and at the end of the winding 'uidethe supply wire into the notches in the ends of the

fingers

14 and 15. v j
