The invention relates to an improved winding machine and in fact to a machine for winding coils for electrical purposes, the primary object of the present invention being to provide an improvedmachine of this charac' ter equipped with improved means for regulating andf controlling the number of turns in the coils wound thereby.
Another object of'the invention is the provision of improved means whereby the numher of .turns or convolutions produced in a coil wound upon the machine may be varied as desired. I
Another object of the invention is the provision of improved means for accurately settingthe machine for controlling the number of turns in the coils wound thereby.
. Other objects will appear hereinafter. T heinvention consists in the combinations and arrangements of parts hereinafter described-and claimed. 7

The preferred form of construction as illustrated in the drawings comprise'an operating shaft 12 mounted in the frame of the machine, as best indicated in Fig. 6, said shaft being driven by means of a grooved pulley 13 connected by a belt 14 with a grooved pulley 15 connected,'as shown, by
mandrel 18 is supported on a yieldable spring held cone bearing 20 whereby said mandrel may be readily removed from the machine when desired.
The mandrel 18 is the member upon which the coils are wound by the machine and suitable paper feeding mechanism is associated with said mandrel and enclosed in the housing 21 by means of which sheets of paper from the strip of'paper 22 from the roll 23, best shown in Fig. 1, are fed onto the mandrelf18'at the proper-times and in the proper manner to insulate the coils wound on iaid mandrel, and constitute a support thereon e Associated with the mandrel 18, also, is a grooved guide roller 24, best shown in Fig- 2, said grooved guide roller being provided with a plurality of grooves as shown adapted and arranged to guide and direct the wires onto said mandrel in the winding operation. The roller 24 is best shown in Fig. 2.
The wires 25 are supplied from spools 26 suitably mounted on the frame of the machine, as best shown in Figs. 1 and 2, said wires passing over guide pulleys 27 and 28, through wiper member 29, over control members 30 and thence under guide rollers 30' to the grooved roller 24, as will be readily understood. The guide roller 24 is operatively connected with suitable mechanism ensuitable gearing 16 with an electric motor closed in the casing 31 and operated from the shaft 12 whereby said guide roller is caused to reciprocate properly to guide the wires onto the mandrel 18 in the formation of the coils thereon.
So much of the mechanism of the machine as has already been described constitutes no part of the present invention and needs no further description here except the statement that the parts shown co-operate together properly to wind the wires 25 on the mandrel 18 and thus form a plurality of coils on said mandrel. These coils usually comprise an inner primary coil and an outer secondary coil superposed thereon, and it is highly desirable to provide said coils with a definite predetermined number of turns or windings in each coil.
The present invention has to do wit-h the mechanism provided in said machine for regulating and determining the number of turns or windings which are to be placed in the coils produced by the maeiiine. At each .evolution of the shaft 12, one turn or winding is imparted to the coil then being produced, so that the regulating and determining of the number of turns or windings in the coils may be effected by regulating and determining the number of revolutions of the shaft 12 as will be readily understood.
To this end theshaft 12 is connected with an extension shaft 32 mounted in a suitable casing or housing 33, as best shown in Fig. 6.
As best shown in Figs. 6 and 11, the shaft 32 carries a worm 34 meshing with a worm wheel 35 carrying a pinion 36 co-axially therewith, as best shown in Figs. 9 and 11.
The pinion 36 meshes with a gear 37 having a central pinion 38 meshing with a gear 39 mounted co-aXially with the worm wheel 35. This arrangement is a reducing gear connection between the worm wheel 35 and the gear 39 whereby the latter is caused to rotate 100 times slower'than the worm wheel 35, each rotation of the gear 39 thereby corresponding to 100 rotations of the worm wheel 35. a
The worm wheel 35 carries a crank pin 40 co-operating with a cam block 41 on a spring switch bar 42 which carries a contact point 43 co-operating with a contact 44 on a cooperating spring switch bar 44 and where by at each revolution of the Worm wheel 35, the crank pin 40 will contact with the cam block 41 thus momentarily forcing the cont acts 43 and 44 into electrical contact with each other.
As best shown in Fig. 3, the contacts 43 and 44 are included in an electric controlling circuit 45 and whereby the crank pin 40 will be caused, at each revolution of the worm wheel 35, to close the circuit 45 at one point.
Co'operating with the crank pin 40 is another crank pin 46 mounted upon the gear 51. The switch bars 48 and 51 are also connected as shown in the electric circuit 45 so that when both the sets of contacts are closed, the circuit 45 is closed.
As will be noted the cam block 47 is somewhat longer than the cam block 41, so that the crank pin 46 will ride or dwell upon the cam block 47 for some little time and thereby hold the contacts and 49 in closing position. The arrangement is such that the contacts 49 and 50 will be held in circuit clos ing position for a period a little less than the time consumed in a complete revolution of the worm wheel 35 so as to insure such contact when crank pin 40 effects closure of the contacts 43 and 44.
The circuit 45 includes an electromagnet 52 co-operating with a spring held armature 53 serving as a trigger detent for a starting lever 54 of an ordinary electric starting box 55. The starting box 55 is connected, as shown, in an electric circuit 56 controlled by a switch 57. The lever 54 is connected with an operating handle 54 and also with a compression spring 58 whereby the circuit 56 may be manually closed at any.
time and the starting lever 54 locked in closing position by means of the detent armature 53. By this arrangement it will be noted that upon closing of the circuit 45, as indicated above, current will be caused to flow across -the circuit 56 and through the electromagnet 52 thereby withdrawing the detent 53 from the lever 54 and permitting the spring 58 to open the circuit 56.
A trip lever 53 is associated with the detent 53, as best shown in Fig. 4, so that at any time desired the detent 53 may be tripped, the lever 54 released and the circuit 56 there by manually broken whenever desired.
Another controlling circuit 59 is made a part of the controlling circuit 45, as shown, said circuit 59 including an electromagnet 60 co-operating with an armature detent 61 engaging a brake lever 62 fulcrumed at 63 and provided with a brake shoe 64 adapted I and arranged to engage a brake wheel 65 on the motor 17, the lever 62 being provided with a handle 66 for manual resetting. The arrangement is such that at each closure of the circuits 45 and 59, current will be caused to flow through the electromagnets 52 and 60 thereby breaking the motor circuit 56 and applying the motor brake 64 to said motor. Closing of the controlling circuits therefor automatically stops the motor 17.
As has been previously indicated, the motor 17 is the driving motor of the machine, so that when the crank pins 40 and 46 cooperate, as described above to close the circuit 45, the lever 54 and the brake shoe 64 will beautomatically operated to break the motor circuit and stop the machine through the agency of said brake, as will be readily understood.
The worm wheel 35 carries a central shaft 67, which in turn carries an indicator finger 68. The gear 39 carries a central hub 69 alsocarrying an indicator finger 70.
A dial 71 is arranged on the outer face of the front plate 72 of the casing 33 and the hub 69 and the shaft 67 are projected outwardly through said face plate 72, as best shown in Fig. 9. The dial 71 is graduated as shown to co-operate respectively with the indicator fingers" 68 and 70, the outer ends of the graduations of said dial being numbered to co-operate with the finger 70, and the inner ends of said graduations being numbered to co-operate with the finger 68. Thus each graduation of said dial 71 means for the finger 68 two revolutions of the shaft 12 and for the finger 70, two hundred revolutions of the shaft ,12.v The fingers 68 and are so positioned relatively to the crank pins 40 and 46 that when said indicator fingers areat the zero point of saiddial, the said crank pins will at that instant operate to close the circuit 45. To insure this, the cam block 47 is made long enough to hold the contacts 50 and 5]. closed during a considerable portion of the last revolution of the worm wheel 35, as will be readily understood.
The front plate 72 of the casing 33 is secured in place by means of screws 73 engaging through slots and notches 74 so as to permit of limited vertical movement of said front plate. The worm Wheel 35 is provided witha central trunnion 75, best shown in Figs. 8, 9 and 10, bearing in a lever 76 ful crumed at 77 in said casing. The other end of the lever 76 carries a pin 7 8 projecting through a slot 79 in said casing and engaging a lever 80 fulcrumed at'81 in said casing.
The lever 81 is operatively connected with a plunger 82 and whereby said levers may be manipulated by depression of said plunger. The lever 76 is normally 'held depressed by a lever spring 76'. By this arrangement, upon depression of the plunger 82, the levers 76 and 80 will be operated to lift the worm wheel 35 from'engagement with the worm 34, the limited vertical movement of the front )late 72 permitting of this. This permitted upward movement of the worm wheel 35 and the gear39 disengages the same for adjustments thus permit ing setting of the indicator fingers 68 and 70, as desired.
In the normal operation of the machine, after the mandrel 18 has been placed therein and the other parts of the machine arranged for winding the coils on said mandrel, the indicator fingers 68 and 7 0 are set to produce the desired number of turns or windings on the coils to be produced on the mandrel 18. Then the plunger 82 is released and the gears and worm Iwheel permitted to reengage. Should there be any error in the setting of thefingers 68 and 70, when the gear 39 and I worm wheel 35 reengagethere will be a slight disturbance of the co-operating pinion 38 relation so that'any slight movement of said gears in reengaging or meshing will be indicated by the blade 85. In such event, the gears are again disengaged by means of the plunger 82 and the indicator fingers 68 and 70 properly reset so that there will be no disturbance of the'indicator blade 85 upon reengagement of the gears. Vhen this occurs theoperator knows that when the operating shaft 12 revolves a suflicient number of times to return the indicator fingers 68 and 70 to the zero mark on the dial 71, the machine will be automatically stopped, thereby insuring exactly the number of turns in the coils as was indicated on the dial 71. In this way the machine may be operated to turn out coils with exactly the predetermined number of turns or windings therein.
When. the machine has been thus operated toplace the desired number of turns or windings in the primary coils, it may be reset, as
indicated above, to place the desired number of turns or windings 1n the secondary coils, superposed upon said primary coils on the mandrel 18, as will be readily understood.
In this manner a machine may be operated and manipulated to produce electrical coils containing both primary and secondary windings in which the number of turns or windings will be accurately numbered and predetermined.
The machine will be found to be capable of operation at high speed and with great efficiency and accuracy. .1
