Pin-ionlS 'drives the .bevel gears V29 and 3i) As illustrated - inrFigjybevel gears 29 and 30 .are secured concentrically to and Within the cirvcumference of the inner facesof electro-magnetic assemblies'l and32 by screws33 so asto be at the magnetic ,neutral :position of the electro-- `magnets-where.they Will not become `rnagnetized and pick.' up metallic particles.
Thus, rotation-of bevel vgears 29and 30 in oppo- :site directions produces corresponding rotation :of `the electro-magnets `3l and 32. -The physical kconnection .of the electro-magnets and bevel gears :produces virtually unitary structures and it may be considered that the electro-magnets are .formed With` gearing .at one .face thereof.
)Both 'the `bevel gears .and .associated electromagnetic assemblies are ireein respectto the tlead screw shaft Siaroundivvhioh they rotate.

Thezco'il winding '40 has one terminal 44' thereof grounded to the core l'whilethe other terminal ,is :le'd lthrough a .port `lll? to contact ring 41.' As will hereinafterappeal', the frame of the device and mechanismimounted thereon may constitute 4'one terminal "of the circuit and it is `therefore referred to as the ground `side of the circuit. Contact ring 41 is insulated.fromthefgrounded -icore 38 by the 'circular insulating memberA 48. 4'Ihusthe coil winding 4c is energized when -a Vs'uitalle electric potential is applied between the groundedstructure :and the contact ring fil.
Brush-49. serves to apply the electricpotential to thefcontact ring 41 during the rotation theredf. .Brush 49 is retained inthe brushhousing 50 and is provided with the usual coil spring and tightening blt 52 for insuring proper electrical contact.
A clutch facing 31 of cambric or the like may be secured as by adhesive to the electro-magnetic assembly for both enhancing the frictional contact in the clutching action, and spacing the disk 56 from the core 3| to overcome the effects of residual magnetism when the coil winding is deenergized. AScrew shaft 34 is suitably journalled at 58, 59 and 89.
The electro-magnetic assembly 32 is of identical construction as assembly 3| above described including the clutch disk 6| which is keyed to the shaft 34 as is its counterpart clutch disk 59.
Referring to Figs. 1 and 2, the rotation of the screw shaft 34 produces the traverse action of the wire guiding structure 62. Follower 83 which travels along the screw shaft 34 in a direction dependent upon the direction of rotation thereof, is formed with arms 84 and 95 which support the traverse shaft 66. Traverse shaft 66 is suitably journalled in the bearings 61 and 68. Secured at 69 to the traverse shaft 69 so as to travel therewith is the wire guide structure 62, the beams of which 10 and 1|l support rollers 12 for guiding the wire W from the wire source or spools 13 to the coil support or spindle I2 for forming thel coil layers as illustrated in Fig. 1.
Wire `spools 13 are supported on individual shafts 14 which are journalled at their ends in bearings 15 and are supplied with any known type `of tension devices 16 for maintaining suitable 'l tension of the wire during the winding operation. Many types of known tension devices are applicable and a conventional type may be employed.
'nalled in bracket 85 and supports a pinion gear Pinion gear 96 meshes with gear 81 which is secured to the jack shaft 88. Secured to the end of the shaft 88 isa control member or control disk' 89 which rotates in a step down ratio when the lknob 9| is manipulated; Control member 89 is provided with two contact arms 99 and 9| whichl .are disposed near the periphery thereof and diametrically opposite each other.
A contact member 92 is secured at 93 to the traverse shaft 66. During the movement of the traverse mechanism the contact member 92 travels therewith but its travel is confined between the contact arms 90 and 9|. It can be seen that the separation of these contact arms in respect to the contact member 92 depends uponthe radial position of the control member 89. For example, the separation of the contact arms is greatest when a line connecting the arms would be perpendicular to the contact member 92. The separation would be least when the arms are in substantial alignment with the contact member 9E. Means to limit the minimum traverse adjustment is provided as hereinafter shown.
Referring to Fig. 3, it can be seen that the pointer 82 is at the 5 inch mark on the indicia 83 and that the contact arms and 9| are separated to almost the maximum distance in respect to contact member 92. Should the pointer be turned to the 6 inch mark the separation of the Contact arms would be greatest. Thus, the manual rotation of knob 8| over indicia 83 fixes or adjusts the separation of the Contact arms in respect to the contact member 92. Control member 89 constitutes a physical connection between the Contact arms which effectively gangs their operation so that simultaneous and identical movements are provided when knob 8| is actuated. The movements are considered identical with respect to contact member 92 because both con- Y tact arms move inwardly and outwardly simuli nut 91 cooperates with a nut 98 in locking the Earm 94 and control member 89 in a desired position. The slot 99 also serves to limit the minimum traverse of the traverse mechanism.
The electrical circuit which controls the traverse mechanism is set forth schematically in Fig. 7. Alternating current is shown as actuating the motor and relay mechanism while direct current is shown as energizing the electro-magnetic coils but this is illustrated for clarity only since it is obvious that other arrangements may be made. One terminal of the D. C. circuit may be grounded to the frame |'0 if desired so that the mechanism mounted thereon assumes ground potential.
In the operation of the device, one of the electro-magnetic assemblies is normally energized so that the traverse structure may travel in a direction depending upon which electro-magnetic assemblyis energized. It may be desirable or necessary under some circumstances to keep the wire guide from travelling. This can be done by opening the common of the D. C. circuit. When it is desired to keep the mandrel |2 stationary while the wire guide travels, a suitable clutch, not shown, on the mandrel may be disengaged.
In Fig. '7, assuming that the contact member 92 is travelling from left to right, it will ultimately make contact with contact arm 9|. This will energize coil 99 of the relay switch |00 and will attract the armature |0| Pawl |02 of armature |0| will thereupon advance ratchet wheel |03 which, being ganged to wheel |04, will shift wheel 04 so that a peak |05 rather than a valley |08 is uppermost. Pin |01 will be then in an elevated rather than in a depressed position and the electro-magnetic coil 40 will be energized.
This relay switch |00 is known in the art and is often referred to as a pulse relay since it is actuated by successive pulses to assume either one of two operating positions. Other types of 5S 'lays -or combinations maybe used, fthe desired function `fleeing fthe establishment ofcontact alternately-with the electro-magnets 3G 4and-531i ac'coxazling--to thesetting of control memberV L39. It willl-beaseenlthat `as contact member 92 strikes either @contact arm, the direction of the traverse mechanism. l`is reversed .since the then open relectro -magnetic structure becomes energized and, .takes .control Afof- .the rotation vor" .the `screw shaft 341while thelfunctioning electro-magnetic `becomes de-energized due to the .opening of .its yfci-rcuitby ithearrnature Il. Condensers may be .disposed across thecontacts `in the conventional Aaman-ner..to eliminateexcessive sparking. Lamps H11-and 4|118 aredisposed in .parallel across electrolmagnets-40 and 4l, respectively, and an arrow f-.together with the .words right .and .left will vimlicate the direction vof ytravel thereof. `A -manually operated control means is provided in IY,trieefiormpf y.pulse switch v92d which by-passes i @thecontrol disk `89 'and permits 4manual control yndependentlylof the contact member 92 or con- ;'tactarms Sil and 9|. Thuschanges may be made `instantly lwhen itis desired to depart from the .pre-determined settings.
lThe .machine is operated as follows:
.-11 Wire Wiisinitially secured around the spindle l2 and the knob is setfor the desired coil length, an operation :whichspaces contact arms 90 and #5.9L equidistantly `from an imaginary line which mepresents the centers yof the coils rto be formed. This yinsures lthe .production of an accurate and `.symmetrical coil winding. This construction has .other desirable features. For example, should gitfbe .required to xwind a transformer with a step down'secondary, the 'knob 8| may be re-set when lithe primary .has been Wound and the secondary will be formed in the precise central area of the primary -since fthe centers of both secondary and primary will be identical and the coils will be iwoundfsymmetrically on both sides of this center. A highlyl superior, transformer and one with balanced .leakage reactance may thus be formed `Awith a minimum 'of adjustment.
;The=contro1 member 48i! having been adjusted aand locked, lthe-traverse shaft 65 may be set so that the .contactmember 92 abuts the left contact armfill `The drive is then applied whereupon ftheftraverse'mechanism travels to the right while depositing .the winding over the paper iB. When the contact member 92 contacts the right control -arm 19|., the traverse mechanism will be shifted asoathat -it will Ktravel to the left. If desired, inr.sulating :paper maybe disposed over the wound .ilayers :after each traverse. The action is con- ;,tinued :until 'the required number of layers is produced.
It`will be seen .that there is provided an extremely compact and simplified mechanism which ,winds coils of considerable merit as regards mechanical and electrical symmetry and pre- Hcision. The electro-magnetic clutch mechanism `...markers possible the traversing action with a minimuml of moving parts since the virtual in- Y corporation of the electro-magnets into the reversible gears eliminates the necessity of a .pivoted clutch arm operated electro-magnetically.
"Thus, 'the electro-magnets are disposed directly around the screw shaft land the clutching action is A'accomplished without interrupting or estabilishing the meshing of gears each time a reversal ofthe traverse is effected. In addition, the trav- 'arse-control means is fool-proof and instantane- L flyfoperated. -'Ihesimple method of setting the Alinob 81 according tothe indicia V83eliminates many'iinwieldly and com-'plex settingsup'zoperaftions. If .largercoils- :are desired, :a control mem- 'ber -of :greater diameter may. be employed. The machine may be .employed 'Where winding cperations .such ias above set forth are required whether coils, transformers -or spools' of wire are to fbe Vproduced. It `is tolbegnoted, however, `that the follower :B3 :is neverdisengaged from the lead screw 4shaft 34. VNo .flag in their engaging .action :is possible. This-.olers Aa considerableadvantage in attaining a high degree of 1 precisionlsince any movement of the screw shaft is translated into vtraverse action whileprior artdevices which :do not main- ..tain :constant engagement permit relative move- .zment' until theengagement ybecomes complete Sand ei'ective.
