ARMATU'BE-VQTINDING IEACHINIE.

Application filed July 30,

T all whom it may concern:

Be it known that I, CLAUDE M. MoCono, a citizen of the United States, residing at Richmond Heights, St. Louis County, State of Missouri, have invented a new and useful Armature-Vi inding Machine, of which the following is a specification.

This invention relates to armature winch ing machines.

An object of the invention is to provide a machine to facilitate. the winding of arms tures by imparting to the armature cores alternating reciprocating and rocking move ments to place the wire in the core slots.

Another object of the invention is to provide a machine for imparting longitudinal and rocking movements to an armature core. and improved means for controlling operation thereof to effect proper timing of the movement during the winding operation.

Other objects will appear from the following description reference being made to the drawing in which Fig. 1 is a longitudinal vertical sectional view of my improved machine.

Fig. 2 is a vertical cross sectional view.

Fig. 3 is a diagrammatic view of the electric operating connections.

Fig. 4 is a detail view showing the means for preventing turning of the rack which imparts axial movements to the axially movable rock shaft by which rocking and longitudinal movements are imparted to the armature core during winding thereof.

In the embodiment of the invention shown an axially movable rock shaft 1 is supported in hearings in the frames 2 for axial and roclsting movements. @ne end of the shaft 1 is equipped with a chuck device 3 for en gaging and supporting a cooperating member 4 on which the armature core 5 is supported. The chuck device 3 has astem 6 extending into the shaft 1 and equipped with a collar 7 abutting against a collar 8 on the shaft 1. The collar 7 is provided with a series of radial holes in its periphery adapted to receive the releasable latch bolt 9 operatively mounted in a support 10 attached to the collar 8. The end of the latch bolt 9 may be provided with a hand wheel or similar manual device 11 by which the bolt 9 may be withdrawn to permit the chuck to be turned to place the armature core in different positions for winding. Obviously if the bolt 9 be held withdrawn during longi- I armature core a guide 13.

- The mechanism for rocking the shaft 1 includes a gear A mounted on the shaft for turning movements therewith in a manner to permit the shaft to move axially through said gear. The gear: is held from axial movements by a frame member 15 having a notch into which the gear 14: is received, leaving said gear 1% free to turn with the shaft 1' and leaving the shaft 1 free for axial movement while the gear 14 is held stationary. A gear 16 is supported on a shaft 1?. A slotted crank arm 18 on the shaft 17 receives a pin 19 on the upper end of a connectin rod 20, the lower end of which has pivotal connection 21 with a ver tically movable member mounted on supporting guides 23. The member 22 supports a pair of spaced rollers 24, between which a cam operates to raise and to lower the member 22 and thereby impart rocking movements to the shaft 17, with the result that rocking movements are also imparted to the shaft 1 and thereby to the The cam 25 is attached to a shaft 26 rotated by worm and gear connections 27 from a shaft 28.

The mechanism for imparting axial move ments to the shaft 1 comprises a rack 29- supported by collars 3O keyed to the shaft 1 by rings 31,3vl1ereby longitudinal movement of the 210k 29 will. move the shaft 1 axially leaving the shaft 1 free to turn without turning the collars 30 or moving the rack 29. The collars 30 are held from turning movements by a depending flange 32 on the member 15 engaging in notches 33 (Fig. 4;) in the collars 30. A gear wheel 34 on a shaft 35 is in constant mesh with the rack 29. A crank arm 36 on the shaft 85 has pin-in-slot connection 3'? with the upper end of a connecting link 38. the lower end of which is pivoted to the upper end of a verti cally movable member 39 having slots 10 for receiving the supporting guides 1-1. The mounting of the member 22 is the same as that of the member 39. The member 89 supports spaced rollers 42 between which a cam 43 on the shaft 26 operates to impart which axial movements are imparted to the shaft 1 and thereby to the armature core 5. V Theshaft 28 is in axial alinement with a power driven shaft 44 and the adjacent ends of the shafts 28 and 44 are equipped with clutch devices 45 preferably of the magnetic type, so that the shaft 28 may be driven by the shaft 44 optionally. Fig. 3 illustrates diagrammatically the mechanism for controlling the machine equipped with a magnetic clutch. As shown the coiled magnetic clutch 45 has one end grounded and the other end in contact with a ring 46 on the clutch member with which a brush 4'? in connection with. a lead wire 48 contacts. The wire 48 leads to a switch 49 from which a wire leads to a battery. A wire 50 from the battery is in connection with a brush 51 contacting with a broken ring 52 on a gear 53 and having an insulating gap 54. The ring 52 is grounded. The gear 53 meshes with and is driven by a pinion 55 on the shaft 26 so that once during each revolution of the gear 53 the circuit is broken by the brush 51 coming in contact with the insulation gap 54. The ratio between the gear53 and the pinion 55 is such that the proper number of reciprocating and rocking movements are imparted to the armature core 5 to place thereon the proper number of windings before the brush 51 comes into contact with the insulation gap 54. Vhen the circuit is broken by the brush 51 coming in contact with the insulation gap 54 the magnetic clutch 45 is deenergized permitting the shaft 28 and the. mechanism operated thereby to stop while the shaft 44 continues to rotate. This is for the purpose of permitting the operator to release the latch de vice 9 and turn the armature core to position to receive the next winding. After the .armature core has been adjusted the machine may be started again by closing a switch .56 having 'a wire 57 leading to the battery and a ground wire 58. The clos of the switch 56 energizes the magnetic clutch with the result that the shaft 28 and the mechanism operated thereby is started causing the pinion 55 to rotate the gear 53 and move the gap 54 beyond the brush 51. After the mechanism has started the opera tor again opens the switch 56, leaving it for the insulation gap 54 to cause the machine to stop at the proper time as before.

The cams 25 and 43 are arranged relatively so that when either cam is imparting movement to the connections controlled thereby the other cam leaves the connection controlled by it'stationary. Thus when the cam 25 is actuating the connections to turn the shaft 1 in either direction the cam 43 is 'making an idle movement to the extent that it does not move the'connections for reciprocating the shaft 1 until after the turning movement of said shaft has stopped; which is at the time that the cam 25 moves without moving the connections controlled by it. So also when the cam 43 imparts axial movements to the shaft 1 the mechanism controlled by the cam 25 for rocking said shaft is stationary.

From the foregoing it will be seen. that my invention is a distinct advance in the art of winding armatures and that the machine is thoroughly complete. The gearing 5355 can be made in such ratio as required to impart the necessary axial and rocking movements to the armature core to receive the necessary number of windings irrespective of the variation in the number of windings of the different armatures. The reciprocating and turning movements of the armature core are effected automatically without special care or attention by the operator and when the proper number of windings are applied to the core the operating mechanism is auton'iatically stopped.

lVhile I have shown and described an appropriate type of machinefor satisfactorily obtaining the desired results, I am aware that the construction and arrangement of the-machine may be widely varied without departure from the nature and principle of the invention. Therefore, I do not restrict myself to the identical form of machine shown, but contemplate such variations as may be desired and as are within the scopeof the appended claims.
