WINDING MACHINE.

Appiieatioii iiled nayei, 1923. serial No. 642,687. j

To all 'Lo/0m t may concern.'

,Be it known that I, NICHOLAS E. GIBSON, a citizen of ythe. United States fof America, residing in Chicago, county -of Cook, .and State of Illinois, have invented kcertain new and useful Improvements in Vinding Machines, of which the following is a speciiioation.

My invention relates in general to winding machines, such as are used for winding bobbins or coils, and Vmost particularly to that class of winding machines forwinding .small clectromagnet coils used Iin connection with telephone receivers and the like. An object f Vof my invention is the provision of .an improved winding devi-ce which is auton'iatic in its reciprocatory movement, simple in construction and positive in its operation.

Electromagnet coils` of the type used in receivers and for various other purposes are small and are usually wound ofy ine gauge wire so that a maximum number of vturns of wire may be placed in a minimum space.

More or less trouble is'eXperieif-iced in winding coils of this Vtype for the reason that when the wire reaches the lend of the spool, that is, upon the completion of a layer of turns, the wire piles up at the start of each new layer at the ends of the spool, ,due -to lthe .factthat most of the coils .of this type are .wound by hand and the dwell at the start of each new layer is prolonged, permitting the wire to pile up before the natural rate of feeding takes place across the spool.

This piling up of the convolutions at each end of thespool produces a pronounced bulge or lump which makes the threading of the outer terminal of the winding through the spool head diflicult, due to the 'bulge which at times completelycovers this opening.

To overcome this 'objectionable feature, I have .designed a Winding machine which eliminates this through the provision oii .a reciprocating member wliichtravels to and fro, and a? feature of my invention is the provision of a tripping anec'hanism in which the instant that a layer of thecoil beiiigwound is ceiiipleted, the movement of the reciprocating member `is reversed to permit- :the travel of the reciprocating feeding `member to start back vin its reverse direction. 4'Ilie tripping means for instantly reversing the direction of travel of the reciprocating .meinber prevents the `wire at .the beginning.ciL a 4with a tension device Y die device Z.

new layer `piling up, thus `producing a smooth coil. Y

Another feature of my invention is the provisiony `Of a novel clutch mechanism in operative relation with the reciprocating member just Adescribed to bring about the automatic reversal of travel of the reciproeating member.

Still another feature ,of my invention is the provision ofnovel supporting means for a shaft whic-li I will term a floating shaft and its adjustment in relation with the reciprocating member so that the said member may be adjusted to trip at the desired instant.

The above features, as well as others, will be more fully described in the ensuing speci-A cation. f

For a more complete understanding of my invention, reference may be had to :the accompanying drawings infwhicli like reference characters in the several vviews denote like parts, and in which:

Fig. 9 illustrates my device X associated and a "windiiw` spintlie line Referring vnew .more in detail to my iiilvention as illustrated in the accompanying drawings, the windingv machine of my iiivciition comprises a suitable rectangular supporting trame F for supporting the winding A shaft il supported in suitable bearings in the sides 3 and 3 of the -fraine F is provided and its? end t extends laterally from the `side of vthe lframe F and is .supported .in an additional `beariii vin an L-,slraped .member o :suitablY supported upon .the ,fname F byineans of a. bracket- (3. A bevel gear i7 is keyed :to the end 1l `of the shaft 3 Cil which meshes with a bevel gear S'which is keyed to a shaft 9. rllie shaft 9 is supported in a suitable bearing in the L-shaped member and may be termed the driving shaft, as this shaft 9 being connected te suitable power, and through the agency of the bevel geais 7 and 8, transmits motion to the sha-ft 2. The shaft 2 has also secured to it a gear wheel 10 by means of a suitable set screw 11 and meshes with a gear Wheel 12 which is secured to a shaft 13 supported in the side 3 of the frame F. The end 14 of the shaft 2 which extends through the bearing in the side 3 of the frame F supports a gear wheel 15 which is secuied thereto by means of a set screw 16. A shaft 17 is located directly below the shaft 2, and in alignment therewith is provided what may be termed a floating shaft for purposes as will presently be described.

Associated with the shaft 17 are a pair of clutches C and C. rl`he clutch C compiises a disk 18 whose face 19 is provided with teeth 19 eut in on the said face 19. A sleeve extension 20 of the clutch disk 18 extends through a suitable opening 21 in the side 3 of the frame F and has secured to this extending sleeve end 2() a gear 22 by means of a key or similar means. The intermediate portion 23 of the shaft 17 is square while its end portions 24 and 25 are cylindrical with its extreme end portions 24 and 25 threaded. An aligning bearing 26' of a size to permit its entrance into the sleeve portion 20 of the disk 18 is provided, and a central orifice 27 extending its length is threaded a portion of its length so as to permit the threaded portion of the orifice 27 to have screw-threaded engagement with the threaded end 24 of the shaft 17. A pair of thrust bearings 2S resting in depressions 29 in the outer and inner face of the side wall 3 of the frame F cooperate with the gear wheel 22 and disk 18 and are for the usual purposes. The clutch C also comprises a clutch disk 3() whose face 31 is provided with teeth cut in the said face 31 and its sleeve extension 33 which extends through asuitable orifice 34 in the side wall 3 of the frame F, and has secured to it iii any suitable manner a gear 35 which meshes with the gear 15 secured to the shaft 2. An aligning bearing 36 of a size to permit its .entrance into the sleeve portion e3 of the disk 30 is provided, and its centi'al orifice 37 which extends its length has a portion of its length threaded so as to permit this threaded portion of the orifice 37 to have screw-threaded engagement with the threaded end 25 of the shaft 17. A pair of thrust bearings 38 cooperates with the gear 35 and disk 30 and are for the usual purposes.4 The aligning bearings 26 and 36 are provided with enlarged ends or heads aiid'41, y which are slotted .foi-...the entrance et' e .sii'table tool so that the said bea- rings 26 and 36 may be threaded upon the threaded portions 24 and 25 of the shaft 17, the said heads 40 and 41 forming shoulders to limit the entrance of the said aligning bearings scribed.

The shaft 17 supports a screw-threaded member 44 which is secured to the square portion 23 of the shaft 17 in any suitable manner, as by means of a force lit, and a block 45 having a threaded orifice 46 has screw-threaded engagement with the meinbei' 44. A T-sliaped reciprocating member R is slidably supported on the shaft 2, and its leg 47 is bifurcat-ed to permit this bifurcated leg 47 to span the block 45, which has screw-threaded engagement with the member 44 on the shaft 17. The legs 48 of the bifurcated portion of the member R are also bifurcated and span the threaded member 44 on the shaft 17. Adjustable members 49 having screw-threaded engagement with suitable tapped orifices in the member R are provided and are for limiting the recip rocating motion of the member R for pur poses as will presently be described.

A rod 50 suitably supported by the walls 3 and 3 of the frame F is provided and slidably supports a rectangulaily shaped member 51 and cooperates with the clutches C and C as will now be described. A pair of U-sliaped members 52 and 53 are secured to the member 51 by means of the screws 54 and the legs 55 and 56 extend upward in proximity to the clutches C and C. Slidably supported on the square portion 23 of the shaft 17 are a pair of disks 57 and 58 whose faces 59 and 60 are provided with teeth 61 and 62 which cooperate with the teeth 2O and 32 of the clutch disks 18. and

30. The disks 57 and 53 are provided with annular grooves 63 and 64, and the upwardly extending legs and 56 of the members and 53 span these disks 57 and 53, and pins 65 secured to the legs 55 and 56 of the members 52 and 53 rest in these annular Cil end74 yis provided with a Slot .7 6 of a size to receive a pin 77 whichfis seciiredfto 'the member R. The Ushaped'.member 52nand 53 are provided With ears 7S and 7 9 to which aresecnred spiral springs 80 and 81,

the other ends of the spi-ral springs y80 and 81 being secured tothe singularly extending end 75 ot the `link 72, This link'72 forms a connection between the reciprocating member R and the slidable member '51 on the rod 50 forpurposes as :will presently be described. v

A pair of 'L-shaped members .82 and 83 are pivotaslly secured 'to the vplate 70 by means of the pivot screws 84 and 85 ,and are operatively associated `with fthe reciprocating rmember fR. ot the ,members -82 and 83 extend npivard and lie in ythe plane of travel of the reciprocating member Rend the : legs 88 and 89 ot :the members -82 andvSB have notches '90 and 91 :which cooperate with Ia plate 92 Secured to the slide-ble member 5l supported,

The legs 8S and S19 -ot' the members S2 -afndfSB `are provided with ears 192 and 93 and la coil spring` is provided having itsoneend 95 'secured to the ear 192 of the member 8 2 and its othe'i` end 96 secured to the ear '193 of theinember 83, the tension of the :spring 94 being such as .to keep .the legs 8S and 89 in engagement with lthe-plate 92 Vfor purposes as will presently be described. Y

Having.,r described the apparat-iis which comprises the Winding machine' of my invcntion, I Wil-l new describe in detail its operation and its adjustable .means prof vided tor'the'mechanism.v

Referring now to Fig. 1, I shoT the ref ciprecating member R in the extreme position of travel vto the ',rliglfit, and ready `to start on itstravel to the lett,and assuming that the driving shaft 9 is rotating in the di'- rection of the arrow, the shaft 2 Willtravel in the directionot the arrow through the agency or" the bevel gears 7 and 8V. `The ,gea-r 10 upon the shaft 2 meshes with tjliegear 12 supported .on -thegshait 13, and #this gear 13 in turn meshes with the rgeary22 secured tothe sleeve.extension 29, ot' the clutch .disk 18 ot the clutch C causing -thisvclutchly disk 1S'and gear 22 to rotatein the vdirection et the arrows indicated thereon. "The gear 15 on the shaft 2 travels in the direction :indicated thereon and Ameshes With the gear Vsecured to the sleeve yextension of the clutch disk of the clutch C consi-ng :the fe-ear 35 and; clutch .disk 30 :to rot te .inthe direction indicatedv thereon.. From Ythe drawings and the description, it may be seen thatihrough the agency `ofthe gears 10,

and 22, the clotchndislc' ot the' clutch C rotates fin the ,direc-tion ais indicated thereroin,and that :through the a'gencj) f @116g '5 1,5 and 35 Athe disk ,5.0 .cog te durch The legs 86 and V87V C yrotates ina direction opposite to the drection of r:the -rotationcf the disk 18 of the clutch C, Vith reference to Fig. 1, the disk as already described, and theclntch dis-lr '8O and :the gear sec-nredto its sleeve extension 33 rotate about the aligning bearings 36S which -ixotates in 4the samel .direct-ion as the s'hait 17, diie to the :threaded `connection between the 'threaded end 25 of the shaft '17, and the threaded portion of the orifice 37 .of the aligning' bearing' 86 ivitlrno etlect at this time. The block i5 which iis in threaded Iengagement with `the member d4 new starts rrael to the lett, ldue to thethreaded connection between members lll and L1.5, and diie -to the biturcatedend ot the reciprocating meinber R straddling the block d5, the member R as a whole travels to the lett sliding along;` the shai-t 2. The linlV connect-ion 72 is now swing abontits pivot 10, due ito thc slot 76 and pin 77 connection between the said link 72 and member R, and its end 71- is tlrus moved tothe left, and its other end 75 ivill; o1: 'course swing' to the rigl-rt and as .the coil springSG has its one end secured to the end 75 otlthe link 72 and its `other end secured to the Vear 78 ot the member 52 secured to Lthe block 51 supported on the rod thftliesprin-g Awill be placed under tension. The block -51 which is s-lidably supported on the rod 50 is heldin its position as clearly illust-rated in Figs. 1 and L1, due to the tact thatthe plate extension 92 of the block 51 rests in the notch 90 of the lee' 88 of the member 82, this member 82 being held in this` position by means of the coil spring connection 921betiveen the two members 82 and lThe connection .between the plate 92 and the notch .90 ot the member S2 also holds =the l member 51 and its supported parts in the position illustrated in Fig. 1 with the disk 57 Vin meshlwith theclntcli disli 1S nntil released as ivi/ll presently be described. iks-the reci procating` member R continues its travelyto the deft, its yadjustable member #19 .will `engapfge vthe 'of fthe, 'SG the member S2 -a ,M canse it to -rocli about its pivot 84, `tglrus movingthe leg 86 ,tothe lett and 'its leg 'BS upward The continued travel ot the member to the lett causes the end 7 5 of the link 72 to swing 'to the righ-t Vto .place the spring Sdugnder-gtension', and at the sanjie gtigmge l the leg 86 of the member 82, the said member 82 is rocked about its pivot 84 to cause the leg 88 of the member 82 to move upward. The instant that the nose 100 of the notch 90 in the member 82 disengages the edge 101 ofV the plate extension 92 of the block 51, the tension of the springpulls the block 51 and its supported parts as a whole to the right along the rod 50, and due to the connection between the disks 57 and 58 and block 51 and its members 52 and 53 secured to the block 51, the disk 57 will also be moved to the right along the square p0rtion 2 3 of the shaft 17 out of engagement with the clutch disk 18 of the clutch C. The block 51 having moved to the right the plate 92 also moves with it, and when the edge 102 of the plate 92 passes the nose 103 of the notch 91 in the leg 89 of the member 83, the said member 83 is caused to rock about its pivot due to the tension of the coil spring 94, and thus force the leg 89 of member 83 downward to permit the plate 92 of the block 51 to rest in the notch 91 in' the leg 89 for purposes as will presently be described.

The U-shaped member 56 secured to the block member 51 is also moved to the right, and due to its connection with the disk 58, it is also moved to the right into engagement with the clutch disk 30 of the clutch C.

The disk 58 now being in engagement with the clutch disk 80 of the clutch C', and as the said clutch disk 80 rotates in a direction opposite that of the clutch disk 18 of the clutch C, due to the gearing connections 15 and 35, the shaft 17 is now rotated in a direct-ion opposite that when the member traveled to the left, and due to the con- .nection between the reciprocating member R and the threaded member 44 on the shaft 17, the said member R now travels to the right causing the link 72 to be rocked about its pivot 73 causing its end 74 to move to the right and its end 75 to the left to place the spring 81 connected between the member 5G and the link 72 under tension. The block 51 and its supported parts remain in the position it was moved to as just described by means of the spring 80 due to the plate. 92 of the said block 51 resting in the notch 91 in the leg 89 of the member 83. In its travel to the right, the adjustable member 49 of the reciprocating member R engages the leg 87 of the member 83 and causes the said member 88 to be rocked about its pivot 85, moving the said leg 87 to the right and its leg 89 upward. Now when the nose 102 of the notch 91 in the leg 89 of the member 83 disengages the edge 103 of the plate 92 of the block 51 the spring 81 which was placed under `tension dueto the movement ofthe end 75 of the link 72 to the left, now pulls the block 51 and its supported parts to the lefty-@using the disk S1-*.30 disengagd lill@ clutch disk 30 of the clutch C and move the disk 57 of the clutch C into engagement with its clutch disk 18. The member 82 now rocks about its pivot 84 permitting its leg 88 moving downward, permitting the plate 92 to again rest in the notch 90 in the said leg 88 of the member 82, and when the mechanism is in this position, the reciprocating member R is again ready to start on its travel to the left.

The distance of travel of the reciprocating member R from left to right and vice versa is controlled by means of the adjustable thimbles 49 and 49 threaded in the member R. Then the thimbles 49 and 49 are turned to bring them closer to the legs 86 and 87 of the members 82 and 83, the distance of travel from left to right and vice versa is shortened, as is readily apparent from the drawings and description. The floating shaft 17 is also adjustable to the left or right so as to place the threaded member 44 secured to the shaft 17 in its correct position so that the travely each way of the reciprocating member R from its center is the same. rlfhis adjustment may be accomplished by loosening the lock screws 42 and 43 and turning the aligning bearings 26 and 36 to move the shaft 17 and its supported member to the right or left as the case may be to place the said threaded member 44 in proper position in relation to the reciprocating member R so that the said reciprocating member R travels equal distances to the right or left from its center. Vhen this adjustment of the member R is secured, the lock lscrews 42 and 43 are again tightened to lock the shaft 17 and the bearings 26 and 36 in their adjusted position.

The reciprocating member R has secured' to it by means of suitable screws 110 a plate 111 which carries a post 112 secured to a hinged member 113. An arm 114 adjustably secured to the post 112 is provided with a suitable looped end through which the wire passes from the supply spool to the bobbin or coil that is being wound.

From the detailed description just given, it may be seen that the winding mechanism is provided with a positive trip mechanism which is tripped the instant that a layer of wire is completed to permit the travel of the reciprocating member R in a reverse direction, and this trip also cooperates to the clutch mechanism C and C so that the instant this trip occurs the direction of travel is reversed. With this positive means of tripping and reversal of travel of the reciprocating member, I am enabled to produce a far superior coil than that produced by means of the hand operated method.

In Figure 9 the device Y is a tensioning device controlling the supply spool of wire, an'd the device Z is the winding spindle which support-s and. rotates the bobba to be ama-92a -v Wound. Thel device-,X automatically feeds the-Wire tothebobbin or spool carried by Z.-

lV-hile l have described a preferred embodiment of my invention,.it is to, be understood that I donot Wish to'rbe limited tothe exact structure as shown, as changes and modifications willV readily suggest themselves, and I therefore aim to cover all such chan-ges and modifica-tions as come Within the spiritl and scope ofthe appended claims,
