To all whom it may concern.-

Be it known that 1, CHARLES Ease-"roe Anonnson, of Providence, in the county of Providence and Stateof Rhode Island, have invented certain new and useful Improve-'- ments in Wire Winding Machines, of which the fcllowingis a specification.

This invention relates to a machine for winding magnetic spools, bobbins, coils, re sistances and all similar windings where bare or insulated wire is spirally applied to a supporting coreor spool. The special objectof this invention is to enable improperly Wound layers of wire to be unwound from the bobbin, spool or magnet.and woundup again upon the supply spool from which it was previously drawn in first being wound," and to accomplish this result without allowing the wire to be come slack. his and other objects of the invention are carried into efi'ectby the ma,- chine illustrated in the accompanying drawings and described and claimed in the following specification. Of the drawings,Figure 1 represents a front elevation of the machine. Fig. 2 represents a side elevation of the same. Fig. 3 representsa detail elevation of the arm for guiding. the wire as the same is wound uponthe spool or bobbin. Fig. 4: represents an elevation of the supply spool and the supporting and driving means for the same. Fig. 4 represents a side elevation of one of the pins for. driving the supply spool, showing the manner in which the same is mounted. Fi 5 represents a sectional view of the under firiver by which the bobbin or spool on which the wire is wound is driven in either directionand by which the supply spool may be driven reversely to ire-wind wire on the supply. spool and draw it from the'co-il-receiving bobbin. Figs. (5 and 7 represent a different formof drivingdevice for retarding the supply spool and driving the same rearwardly.

The same reference characters indicate the same parts in all the figures. Referrin represents a table or each by which the to the draw ngs, 1

parts of the machine are supported.

2 and 3 are standards which carryce-nters for-supporting the supply spool t whence the wire used in making the electro-mag netic or other. coil is drawn. The spool is held centrally upon an arbor or spindle 5 having a conical head 6 at one end and a tapered not 7 threaded upon its other end, whichfcla-mp and center the spool. The arbor 5 is hung so as to rotate between the centerss8 and 9 in the standards, of which the former is adjustable and is clamped by the set-screw 10. Upon the head/6 of the arbor is mounted a pulley 11 around which passes a belt or cord 12 fastened to the bench 1 and capable of being varied in tension to exert a frictional resistance on the pulley to give the necessary tension for holding the wire taut as it is drawn from the spool.

In a bearing in the standard 3 is a shaft ls'whichengages with the arbor 5 through pins .14 and 141, the former being carriedby the arbor or spindle and the latter byfacollar 142 fastened to the shaft 13.

The pin 141 projects from the face of the collar 142 approximately parallel with shaft 18, being set in a socket in the collar and pressed outward by a spring 143. A shoulder 1&4 on the pin engages a lip 145 on the collar and thereby prevents the pin from being wholly expelled from the collar. The outer end of the pin 141 is beveled, while the end of the pin 14 13 preferably square. These pins are equi-distant from the axis of the shaft and arbor so thatwhen either is rotated, it will engage the other. The engagement with pin 41 occurs on the beveled face 146 thereof, and when the latter is acting as the driver, and a greater resistance is opposed by the wire than the friction whichthe beveled face exerts -on the pin 14, the pin 141 will be forced backward against the pressure of the spring andwill be thereby enabled to slip past and relieve the tension. Fastened to the shaft so as to rotate therewith is a disk 15 having on one'face a frictional covering 16, and beside the disk is a pulley l7-loose on the shaft, being held thereon byfa collar 18.. In the hub of the pulley is a" groove 19 in which enter pins 20 1 Patented Mar. 4., 1913.

. which is grasped ries guide pulleys 51 and 21 which is fastened to a. rock-shaft 22.. Also mounted upon the rock-shaft through a I shown). A spring associated. 'with the treadle tends to raiscthe link, and through the arms 23 and :21, to move the pulley 1'? away from the disk 15. When these arts are thus separated, the spool and sha t 13 are free to turn in the direction caused by the drawing oil of the wire, but when the pulley is pressed against the frictionaFsurface, the spool is driven by the lattergin the reverse direction. A belt. 25 passes over the pulley l7 and is driven in the necessary di rection to turn the spool as above described.

At the front of the machine is a shaft 26 turning in hearings in. the standards 27 and 28. On the shaft is a chuck 29 of any'suitable description, having clamping jaws, by one end of a magnetic core 30 or any other spool, bcbbin'or the like on which the wire is adapted to be wound. .31 is a hand-wheel by which the shaft and core may be turned, and 32 is a pulley over which carried by a forked arm a driving belt 33 passes for driving them by power.

Between the supply spool and the coilreceiving core 30. are guiding devices for properly leading the wire to the coil re ceiver;v These guiding devices include a spring-controlled pulley 34 for always keeping the wire under uni-form tension, preventing breakage of the wire from excessive strain and also taking up any slack which may be caused by unequal receiver and supply'spooL' The pulley '34 is rotatably mounted on a carrier block qr frame 35,sustained by a spring 36 and guided upon wires 37 and 38 extending from eyes 39 on the Phase to the top of a sup orting column 40. The-spring 36 has su icient length and flexibility togive the guide pulley a wide range of movement up and down on the wires.

After leaving the pulley 34:, the. wire passes over a second guide pulley 41 in the same plane therewith, which is carried by a bracket 4C2 on a post or column 43, Onythe same column is a swivelly-mounted swinging frame 431 supported by collars 4.4, which carries a pulley .45 over which, the wire passes after leaving the pulley 41. These pulleys are so arranged that the receiving side of the former is in vertical alinement with the point where the wire leaves the latter so that there wire slipping from either frame is angularly moved. This frame carries ears 4-6 47 to which are pivoted arms 48 on a. second swingingfraine 49, which car- 52. These pul leys successively engage and lead the wire to the coil receiver after it is delivered from pulley as the is an arm 23 which is connected link 2& with a treadlev (not speed or" the coil will be no danger of the on a main driving shaft 71. The

the pulley 45. By reason of the pivotal mounting of the frames 431 and 4.9, which are normally arranged at, right angles to each other, a movement of the delivery pulley 52 in two directions,

nally of the coil receiver and also toward and away'from the samethe-wir'e is wound upon the roll 52 is caused to move wire .from one end to the other thereof, causing the convolutions by side without kinks.

In order to vent its swinging excessively, I provide a deadening or retarding device consisting.

of, a cup .or tank supported 'helo'w'the.

extend blades or vanesframe 431, into-which 54 carried by a shaft-55 sqcured to the sec, ond frame or crane 49. The tank preferably contains a somewhat viscous fluid, such as heavy oil, which sufiicientl-y deadcns or retards the motion of the from, swinging appreciably after the cessationof a lateral impulse.

It will be noted that the frames ,4-3l'and 49 together constitute an articulated Wire guide, of which one portion extends approximately parallel and the other perpen' dicular to the axis .of the coil receiver. Thereby the guide is adapted to conduct the wire to its proper position on the receiver and to move away from. the latter as its ward the same when wire is unwound therefrom and a decreasein diameter takes place.

As before stated, the coil receiver is driven by the belt '33. This belt passes over a pulley .56' on a counter-shaft .57 Whichpasses loosely through hearings in hangers 58 and 59 be neath thebench. The shaft is movable endwise as well as rotatable in bearings, and the pulley is securely fastened thereto so as to partake of all of its movements, the fastening means being permissibly a set-screw 60, shown in. Fig. 5. Flanking the tight pulley are loose pulleys 61- and 82 contained between thehanger 58 and the endof a sleeve 63 surrounding the shaft and lined within the hanger 59. Springs 64: and'b'fi are into lie closely side.

steady the frame 49 and preframeetll to keep it diameter increases, as well as to move to-,

that; is, longitudi is permitted. 1 As core, the delivery j andto guide the tel-posed between the tight pulley and the loose pulleys so as to hold the latter away from the former. Layers 66 of frictional material are contained between the adjacent faces of the pulleys.

The loose pulleys are connected by belts 67 and 68 with pulleys 69 and 70 respectively, belt 67 is crossed and the belt 68 open, so that the pulleys rotate in opposite directions. A shipping lever 72 is pivoted to the bench and has a forked end carrying pins which enter a peripheral oove in a collar 73 fixed to one end of the s aft. As will be readily apparent, swinging of the lever will move the shaft endwise and carry-the fast pulley into' frictional contact-with either of the loose pullc'ys so-that the coil'reeeiver' may be caiised to turn in either directional; will.

When the shipping lever is releasedby the operator, the springs immediately separate V the pulleys so that the coil-receiver comes to rest.

A third belt '54- is driven by the shaft 71 end passes about a pulley 7 5 loosely mounted upon the sleeve 63.. lIhis pulley also is'sur rounded by the belt 25 which passes about the pulley 17 to drive the spool l, as above described. All the belts are preferably driven in the directions indiceted by the arrows in Fig. :2,

in winding the wire upon the coil re ceiver, the shipping lever is thrown over so es to connect the fast pulley with the pulley 61. This causes the coil receiver to be turned in lef hsnci rotation to wind up the wire on the bobbin or core and draw the wire from the supply spool. This action continues as long as the. wire continues to be laid smoothly and evenly on the coil receiver. In case any inaccuracy occurs, and

the convolution's become either too widely spaced or too much crowded together, so

that one climbs up on another, the incorrectly wound portions can be immediately withdrawn by reversing the; rotation of the coil receiver and driving the spool backwardly. After'the incorrcctlywound coils have been removed, the coil receiver is again started in. the forward direction and the supply spool released so that the winding may continue as before.

In melting the reversal for back winding, the pulley 17 is first engaged with the friction surface of the disk 15 by pressure on the operating treadle, and subsequently the shipping lever 72 is thrown over to reverse the bobbin. This mode of procedure insures that the wire will be ltept taut, and thereby eliminates danger of bends and kinks being formed by reason of the wire being released from the bobbin before bein taken up on the supply spool. Tlic yielding guide 3st compensates for the Wire which is wound up on the spool before the bobbin is started, revcrsely. This feature, thatis, the capa bility of backwinding, to take off improperly wound parts of the wire, is of the greatest importance, since it permits any amount of \\'irc, even the whole coil, if necessary, to be replaced on the supply spool in condition I to be again wound upon the coil when necssary.

ln Figs. 6 and 7, I have shown a construction in which the same'devicc serves both as a tension to hold the wire taut while being drawn from the supply spool, and asthe'= driver for rotating the spool reversely to rewind the wire. In this construction the tension device 12 and the driving pins 14% and 141 are omitted, being replaced by srrns 14:7 and I LS-secured to the collar 1.42, while the spindle or arbor is formed with a cylindrical drum portion 1 19. The arms projectbeyond the center 9 so as to lie in the same perpendicular plane with the drum, and secured to one of them, as 148, is a spring strip 150. This strip is notched at the end adjacent to the arm 147 through which passes a screw 151 threaded into the lest-named arm. This screw has a knurled finger-hold 152 by which itmay be turned to draw the end of the spring toward or allow it toseparate from the arm 1A7.

A piece of felt or other frictional material 153 is fastened to the springso as to bear against the drum 149. By turning the screw 151, the pressure with. which the felt acts may be made greater or less, thereby varying the tension of the wire and governing the pull which the driving shaft 13 exerts when driven to re-wind the wire.

it will be noted that both forms of rewinding driver act on the same principle, that is, they turn the spool through friction which may be made of great enough force to wind the wire suitably, while permitting slip in case the tension becomes too great, in order to eliminate danger of breaking or stretching the wire or the insulation of the latter. 141 is reinforced and governed by the spring 143, while that or" the drive, shown in Figs. 6 and 7, is governed by the spring 150 and screw 151.
