Specification of Letters Patent.

Patented June 4L, 1912.

Application filed March 25, 1907. Serial No. 354,317.

chine whereby the material may be rapidly` wound on spools of different sizes and.

shapes in a reliable, accurate and efficient manner.

My .invention relates morey specifically to the winding of 'fine wires and threads which are,y easily broken and which, therefore, require a delicate machine in handling.

While my machine is capable of a wide range of uses and is in no sense limited to this application, it finds a particular field of usefulness in the spooling .of fine Wire in connection with an insulating machine. This machine forms the subject matter of my Patent No. 919,470 of Sept. 19, 1909. In order that fine wire may be insulated at a rapid rate, itis necessary that some provision be made for rapid spooling. I have found that a machine of this character may be very etiiciently controlled by means ofan electric current. A

In carrying out `my invention I attach the winding spindle directly tothe armature of a series wound mot-or. The wire .is-positively fed to the winding spindle by means of another motor. The motor of the-windsion is thus maintained; A machine of this type will handle two and three mil wire atthe rate of from 400 to 600 feet per minute.

Running at this rate of speed it is evident, especially with a copperwire hea-ted, that the tension mustbe adjusted in a very even and delicate manner. I also provide electrically controlled means for varying the length of throw of the uiding device so as to give a taper end spo.

Other features of construction and objects of my invention will be made to appear in the course of the-following specification, in which I have shown my invention embodied in a concrete form.

In the drawings in which `the mechanism y of screw 15,.

is shown and which embodies my features of novelty, Figure 1 is a front elevation of the machine; Fig. 2 is a side elevation of the same; Fig. 3 -is a rear elevation of the upper portion of the machine showing the sole noids which control the switching mechanism; Fig. 4 is a side elevation of the same;

lFig. 5is an elevat-ion partly in section of t-he mechanism for reversing the throw of the guide; Fig 6 is a side elevation of the same; Fig. '7 is a det-ail of the magnetic clutch mechanism; Fig. 8 is a detail of the mechanism for shifting the guide away from the spindle; Fig. 9 is a diagram 'of the circuit; Fig. 10 is a detail of the bearing collars; and Fig. 11 is a detail of the magnetic clutch showing the parts in two positions by means offull and dotted lines.

' Referring to the drawings for a complete description of my invention, the machine :may be said to consist broadly of a spooling mechanism driven by the motor 10 and the feeding mechanism driven by the motor 11.

The spool or bobbin 12 from which the wire is unwound is positively driven/by means of belts 13 and 14 and friction drive 15 and the feeding speed may be varied by means When the armature shaft 16 isdriven from the motor 11, the wire is positively 'fed ofl assing between tension rolls 17 thence to t e insulating machine or .to the winding spindle direct, depending upon the usev to which the machine is to be put. The wire is fed to the winding spool 18 through the guide 19. .The motor 11 may be of any desired type, such as a vconstant speed motor ofthe shunt wound type.; The motor 10, however, is preferably a series wound motor havingA its armature vertically arranged and having the armature'shaft 20 extending so as to receive a driving pinion 21 and a driving spindle 22 upon which the spool or bobbin is mounted. `The armature of the motor 10 is secured to the frame work of the machine, which consists essentially of uprights 23 secured together at their lupper ends, having a bracket A24,` extendingoutward so as'to form a bearing for the upper end of the driving spindle 22. The spindle runs onascrew center 25, which is mounted upon pivoted arm 25 which is swung outward when itis desired to remove or `insert a spool. 'The spindle 22 thus has a. positive armature of the motor 10, and its speed can only vary as the speed of the motor itself varies.

lThe guide 19 which feeds the wire to the spindle is carried b a head 26 having a screw engagementwith a lead screw 27, t e upper end of which has a bearing in the frame at 28 and to t-he lower end of which are secured a pairof friction disks .29 and 30. The friction gear 31 mounted upon a shaft 32 and driven from pinion 21 by gear 33, rotates between the two friction'disksand engages either one, depending upon the position of the controlling parts. This will therefore drive screw 27 either in one direction or the other, and the head 26 carrying the guide will have a movement longitudinal ly of the spindle in both directions. The reversal of the screw is accomplished by means of a pair of solenoids 34 and 35, each having a movable core 36, the upper end of which is pivoted to a cross arm 37. This cross arm is pivoted at 38 to the frame of the machine and at its central portion is yoke-shaped so as to engage the collar 39 with a slot and pin connection 40. This collar is loose on sleeve 40 and supported by ball bearings between bearing collars 4l which are keyed to the sleeve and rotate with the disks 29 and 30. The sleeve is i11- tegral with disks 29 and 30, and is splined to screw-shaft 27. The cores 36 are pivoted at their upper ends to the cross arm 37 through links 42 which are held in a raised position by springs 43. When one of.. the solenoids, as for instance 35, is energized, its core is pulled down to the posit-ion shown in Fig. 5. This movement causes the portion of the cross arm 37, provided with a pin andslot connection, to rise' thereby carrying with it the collars 41 which in turn carry the lower friction disk-30 into operating engagement with the friction gear 31. Similarly when the solenoid-34 is energized and solenoid 35 denergized, a driving connection is made with the friction disk 29. 'lhe springs 43 cause a yielding pressure between the gear and the disks. The manner of operating the solenoids will be hereinafter described.

In the winding of fine wire it is essential for the guide to be very close to the spool which is being wound, and as the spool gets larger the guide must, of course, be moved farther from the center. This operation I accomplish automatically by an elect-romagnetic mechanism. The yguide 19 is Vadjustably secured to an arm 44 pivotally secured te the head 26, the uide member 45 having a guide clip 46 whic slides'up and down on the frame. The arm has a spring-pressed extension 47 which supports the outer end of the membe 45. Arm 44 is connected with rod 48 by a-link 49. The rod 48 is moved in and out from the frame by an tromagnets 52 secured to a disk 53 sliding on a shaft 54. The disk 53 has an arm 55 pivoted at 56 to the core 57 of solenoid 5l. Magnet-s 52 coperate with a disk 57 secured to the shaft 54, so that when the magnets are energizedy theyv will move.- up to the disk 57. against the tension ofthe spring 69 and then'upon the energizing of the solenoid 51, the disk 53 is rotated carrying .with it the magnets, the disk 57 and the shaft 54, which in turn moves the rod 48 by means of the thread 54 which slides nut 48 in and out as shown in Fig. 4. When the magnets are denergized the spring 58 returns the disk to its original position which may be adjusted by the screw 59. Shaft 54 may be turned by hand by means of the screw 60. The arrangement of circuits is such that the magnetic clutches and the solenoid are magnetlzed once during. each throw of the guide, and the latter is moved outward from the center a dist-ance equal to the thickness of the layer formed upon the spool. The guide thus maintains a fixed distance from the surface of the spindle, and a greater degree of smoothness of the layers is accomplished.

In the winding of line wire and the like it is desirable that a taper ended spool be employed so as to prevent the ,lastturn of the layer from sinking beneath the other turns and thus prevent the free unwinding of the spool. In order to adapt my machine for a taper spool 'I employ the mechanism shown in Figs. 3, 4 and 9. This mechanism consists of contact plates 61 and 62 forming terminals for the solcnoids 34 and 35 respectively, the plates being separated by an insulating rib 63. A spring contact 64'is se- -cured to the head 26 and moved back and forth thereby over the contact plates. The plates and the rib 63 are set at an angle to the direction of travel of the contact, which is bent inward and normally engages the rib at or about a point intermediate the ends of the rib. As the contact-moves in one direction therefore from its central point, the rib will place the spring arm under tension by moving it laterally. As the contact moves along the rib the tension increases untilthe Aend of the rib is reached whereupon the contact will spring past the rib and on to the opposite contact plate thereby Aenergizing the other solenoid, which re verses the direction of rotation of the screw. The contact is thereupon carried back in an opposite direction, and after it passes the central point of the rib again engages it and when the end of the rib is reached the contact `again snaps over on the opposite contact surface, this operation continuing to automatically reverse the movement of the guide. In order to make each layer of wire,

longer than the preceding one, as is necessary in the taper ended spool, 'Iy make each successive throw of the guide longer by automatically increasing the leffective length of the rib. To accomplish this I form the rib in, two parts 65 and 66 sliding to and vfrom each other between the contact plates. Each section is independently operated by a magnetic clutch, the upper section being operated by clutch magnet 67 and the lower one by magnets 68. These two clutches are identical in construction and operation with the magnetic clutch mechanism described above. When the magnets 68 are energized they move longitudinally of the shaft 69 against the tension of a spring into engagement with the disk 70 keyed to the shaft 69. `When the solenoid 71 is energized the disk. upon which the magnets are mounted is given a partial revolution thereby rotating the shaft 69. This shaft- 69 carries a lscrew-thread which engages with an adjustable nut 72 to which the section 65 of the rib is secured. In this way eachtime the magnets 67 and the solenoid 71 are energized the section 65 of the rib is moved outward, an increment which may be adjusted by means of the screw 73. In a similar way the lower section 66 is moved vupward by a similar clutch magnet 68 and solenoid 74. The shafts 69 may be turned by hand by means of the screwheads 75. A

rPhe arrangement of circuits and the mode of operation will now be described,p,articu lar reference being made to Fig. 9 of the drawings. To start the machine the switch 76 is closed whereupon current will flow from main 77 through rheostat 78,.series motor 10, switch 76 and back to line at 79', placing a tension fon the wire. Switch 79 is then closed, 4whereupon current will pass through the shunt wound motor 11 having a rheostat- 80 in series with its armature. The feeding device .will thereupon be started and wire will be fed to the guide 19. The winding spindle upon which the spool 18 is mounted willalso be started and the winding head 26 will start to move in one direction depending upon t-he position of the 'partsgas for inst-ance downward. During a I movement, as, for instance, downward, as shown in. Fig. 9, the contactor 64 is in engagement with t-he plate 61 and solenoid 34 is energized as follows: from main 79', conductor 81, solenoidv 54, conductor 82, plate 61, contactor 64 to the terminal 83 carried by' head 26 and conductor 84 back to line at 77. `The solenoid 34.- being energized the friction gear 31 is held in contact with the upper friction diskf29. The head 26 thus ltravels downward placing a tension upon the contactor arm 64 causing it to bend as shownin Fig. 9. When the end of the rib is reached the contactor will spring back 'tor 85,.plate 62, contactor 64, terminal 83,

conductor 84 and back to line. The energizing of solenoid 35 moves the friction wheel 31 into engagement. withl vthe lower friction disk-30 as shown in Figs. 5 and 6 thereby reversing the direction of rotation -of the lead screw. The head thereupon starts to move upward and when the end of 'the rib is reached the cycle of operations is repeated.

The head 26 carries a finger 86 which engages a flexible contact 87 vibrating between the contacts 88 and 89. These contacts are mounted on the frame so that the finger 86 will engage contact 87 at a point intermediate the limits of travel of the head. These contacts control the circuits of the magnetic clutch 53 and solenoid 51 as well as the solenoids 71 and 74 and their corresponding clutches 67, 68 and 53. As the finger 86 travels downward, it will engage the spring contact 87 thereby energizing magnetic clutches 67, (38 and 53, which are in parallel, as follows: from main 77 to finger 86, thence-through spring contact 87, coils of clutches 67, 68 and 53, in parallel and resistance R back to line at 79. The movement of the finger 86 continuing, spring 87 will be forced downward into engagement with Athe contact 89, as shown in dotted lilies in Fig. 9. A circuit will there- Yupon be completed in addition to that above described through solenoids 51 and 74, as follows: from contact 89, conductor 90, solenoid 74, conductor 91, solenoid 51 and conductor '92 back to line. The energizing of the solenoid 74 causes shaft 69 to be rotated slightly thereby moving the upper section 65 of the rib outward. The energizing of vthe solenoid 51 causes the guide 19 to be moved backward from the spool as above descrlbed. The finger continuing to move,

disengages with the contact 87 and dee-nergizes all of the solenoids and clutches. On

its return movement a similar cycle of operations is gone through. In this way the guide will continue to move back and forth, 'each time moving a-little farther, and as each additional .layer is wound on the spool the guide is moved away from the spool a proper amount.

I consider that the driving of the winding spindle directly by means of a variable speed motor is an rimportant feature of my invention since it allows the spindle to wind up only as fast as the wire is fed to it, and the speed of the motor is proportioned with the load,that is, as the speed of feeding is varied, the speed of spooling will he automatically and proportionally varied, withlll@ d obtain a layer winding, since the leading speed will beautomatically varied to suit the speed of the spool. I also consider my electric control including the electromagnetic reversing mechanism as well as the arrangement for tapering the spools a very important and convenient one, especially where fine wire is being wound. It will, of course, be understood that while I have shown my invention in its preferred form, I do not intend to limit my invention to the specic construction or arrangement shown and described, since many changes and modifications will suggest themselves to those skilled in the art all of which come within the spirit of my invention in sofar as they fall within the scope of the claims annexed hereto.
