Schnebelen, Toledo, Ohio Application December 18, 1944, Serial No. 568,758 4 Claims. (01. 242-13) 2 1 gized electromagnet draws the armature 24 to abut the faces | 9 to be there magnetically locked or held. In this transit to the holding position for work thereon, the armature 24 is so shifted as to have a slot 2% of the armature entered by the indexing pin 23. The deflector portions or guides This invention relates to the winding of coils into slots, more particularly in electrical work. This invention has utility when incorporated in ready mounting or holding and control of the part to be wound, as an armature, and the carry me thru of the successive steps therefor to com plete the winding of such article. Referring to the drawing: Fig. l is a side elevation, with parts broken 22 are so located that from a coil supply 2'! to pass the right of Fig. 1; is directed to be wrapped directly into the pair of Fig. 4 is a plan View of the holder of Fig. 3, portions being broken away to show details of the slots of the armature. 'sion armature. nated total. 7 over a guide roller 28, the insulated wire 29 to be wrapped will be directed, upon the rotation of the away, of an embodiment of the invention in an 10 shaft ‘f, to enter a slot 26 of the armature 24, then pass across the end of the armature 24 clear armature winder; of its shaft to enter a second slot in the winding Fig. 2 is a wiring diagram of the electrical con pair for the armature coil. The guides or de nections and controls for the winder of Fig. 1; flectors 22 are so con?gured, that at the location Fig. 3 is a detail view, on an enlarged scale, looking into the armature holder or head from v15 of the feed direction for the wire 29, the wire‘ 29 ' V i t From the drive shaft 4, a transmission 30 ex tends to a counter device 3| to operate a cut-out electromagnet; and Fig. 5 is a fragmentary View of a substitute 20 switch 32 as the number of turns of wire 29 in a pair of armature slots 25 comes to the desig guide and seat as an adapter to a different dimen The drive An electric motor I has belt transmission 2’ 25 therefrom, adapted thru magnetic clutch 3 to be ' cut in to drive a shaft 4 extending into speed‘ reduction housing 5. The speed reduction in the housing 5 may have a manual adjustment or ‘con-1 trol 6 to vary the speed of a shaft ‘l. The electromagnetic holder The device of the invention may be mounted by a set screw 8 to rotate with the shaft 7. The set screw 8 is in a head member or overhangS having thereon an insulation sleeve H) for a pair of slip rings ||, |2. The member 9 terminates therebeyond in a block |3 of nonmagnetic mate rial. Bolts |4 thru the block l3 mount magnet legs H3 in parallel. A bolt l6 therebetween has a mag netic core H in an electric coil winding l8, The free ends of the legs I5, remote from the block |3, have are faces or seat portions l9. Screws 20 in thelegs l5 may mount a non In the event the power supply be alternating electric current. it is then ‘desirable to minimize. the hysteresis loss and have the electromagnet laminated. For direct current power supply to the coil 18 of the electromagnet, the core H and ‘ 30 legs l5 may or may not be laminated Upon throwing in or closing a switch 33, electric power supply line 34 is connected to the motor | with its circuit completed to the circuit completing power line 35, to start the motor |. The closing of the switch 33 does nothing else 35 but start the motor I. The operator determines the number of turns of wire to be placed in the pair of slots of the armature. Should stop pin 36 be not properly located therefor at the counter 40 device 3%, the pin 36 is relocated in the proper adjustment opening 3‘! therefor. Arm 38 in cam disk 39 is then swung against the properly located pin 36. In so doing, a stop 40 is moved by the cam against the resistance of a spring 4| to 45 close the switch 32. The operator may then magnetic guide comprising end seat portions 2| between the legs l5, and outwardly and rear wardly extending de?ector plate portions 22. The parallel arc seat portions 2| medially have an in 50 dexing pin 23. Mounting an armature to be wound ‘ The control close a switch 152 on the front of the housing 5 as a manual control cut in for the coil l8. The electromagnetic holder is now energized for the placement of the article of work, as an armature 24 in the rotary head or holder to be there in dexed and at once looked magnetically. It is next in order for the operator to step on a switch 43, which is effective, with the switches 33, 32, The article of work, as an armature 24, upon also closed, now to energize the magnetic clutch approach to the arc seats 2|, has its ends 25 ride just inside the seat faces 2|, for the ener 55 3. The motor | is now effective thru the shaft 3 2,409,394 4 and the speed reduction in the housing 5, to rotate the shaft 1 and the winding head thereon carrying the armature 24. The operator may at any time stop the rotation of the winding head and armature 24, by releasing the switch 43. This does not disturb the counter device 3| and its switch 32. Accordingly, should such stop by the operator be to cure some defect in thewire, then at once such be recti?ed, the winding con 4 extending from the support and forming a seat complementary to a. longitudinally slotted arma ture adapted to be magnetically locked therewith as an article of work, and non-magnetic guide wings mounted on the poles for directing wire to be wound directly to exposed slots adjacent the seat. 7 2. A coil winder comprising a pair of opposite pole magnet arc faced seats adapted directly to tinuation is automatically effective to the initial 10 engage‘ armature face ‘portions as bounding ar total, when the switch 32 is opened by the rota mature slots, energizing means for the poles for tion of the cam disk 39 clockwise (Fig. 2)_ per the magnetic circuit therefrom to be completed mitting the stop 40 to be drawn into the cam thru an armature at the pole seats, and non-mag recess by the spring 4|. The operator may then netic means carried by the winder poles adjacent open the switch 42 to release the armature 24, 15 the seats providing end seats between which the so that it may be rocked to the next slot pair to armature is located by the energizing of the poles, receive the succeeding coil. Closing of the switch said non-magnetic means having ?are outward 42 is then effective to relock the armature in the wing connections to ‘direct wire to be wound to new or reset position. Stepping on the switch Ward the slots of the armature upon relative ro 43 is delayed until the arm 38 has been thrust 20 tation thereof. against the pin 35. With such preliminary cared 3.

In lieu of the poles !5, 25 line windings to form a coil by winding into a there may be poles 44, with projecting fingers 45 to pair of slots, de?ector means carried by the head be attached as inter?tting with projections 46 to extend toward but short of to the shaft, and with which there is ?xed arc seat face 41 upon a adapted upon rotation of the head to direct the different radius than that of the seat I 9, when for line to be wound from a supply into the pair of a different diameter article of work. As end keeps 30. slots of the article in the head, and selective elec or limit stops, arc means 48 (Fig. 5) are of a form trical control means for locking the article to the to coa-ct in the same manner as the arc end seats head andv releasing it therefrom, and for stopping 2|. vIn this adaptation, instead of assembly of the head after a predetermined number of rota the de?ectors 22 and seats 2|, with the head, the tions.
