UNITED STATE JOHN WILLIAM PLEASANT, or VALLEY JUNCTIQN, IOWA.

Y COIL WINDER.

Application filed July 1o, 1926t serial N5. v121,658'.

My invention relates to coil winders of the type adapted to be mounted on afrotating spindle for Winding coils and field windings for generators, mot-ors and the like.

The purpose of my `invention is to providel a coil Winder of simple, durable and inexpensive construction. e

`More particularly, it is my purpose to provide a coil Winder, having parts so constructedand'arranged as to produce a device having a Wide range for .winding coils of different lengths, the device being quickly and, eas.ily adjustable to any point in its range.l Y

Another purpose isto provide such a coil Winder having partsso"constructed and arranged as to facilitate the speed of Winding and handling the coils. e e

It is aspecial purpose of my invention to provide in a coil Winder novel means for holding the leads, so that they Will be out of.

the. way of theeufinding operation and yet will not be inclined to ycause any substantial bend in the wire.

In carrying out my purpose, it is my object to` provide novel means for holding and threading the wire on the Winder.

Still another object is to provide an effective device for shortening thedistance between the Winding spools for facilitating the easy removal of the finished coils.

Another object. is to provide a novel and simple means for quickly yand easily adjusting the machine for varying the width of the coils, andv simple means y for varying the thickness ofr the coils. Y

lVith these and other objects in view, my invention consists in thel construct-ion, arrangement and combination ofthe various parts of my coil Winder, whereby the objects contemplated are attained, as `hereinafter more fully set fort-h, pointed out in my claims, andfillustrated in the accompanying drawings, in which: c j e e Figure 1 is a frontv elevation of av coil Winder embodying my invention.

, In Winding coils for generators, r convenience in handling the Wire and speed 0f operation are important considerations..v

, My machine rhas numerousv features, which will ber hereinafter especially mentioned, which facilitate the convenient liandling of the Wire and speed ofthe coil windmg. ,c

j A coil Winder should also, if possible, have means for holding therleads out ofthe way of the wire being wound :and With 'such Ameans shouldnot be such as rto make any substantial bend in the Wire. ,This feature also is found in my will be seen. y i

vItfwill be understood that my coil Winder is used in connection withamachine having an operating shaft or spindle.

For' convenience in eplaining the. arrangement and operation of my device, I have shown in somewhat y diagrammatic form in F igure. 3v a machine of the type Which'can be used with my coil Winder. This machine comprises aframe indicated generally in the drawings by the reference character 10. Supported on themachine is a shaft 11 onk which isa belt pulley 12.

On the frame. 10 is supported' also a present coil v,Winder as motor 13 having the belt pulley 14.. A belt 15 travels on the pulleys 12 and 14 and over the idler pulleys 16. A belt tightener pulley 17 issupported on av swinging arm 1 8. e A

rod 19 is connected with the swinging arm 18k and has on it the foot pedal20,lwhich may be ldepressed for tightening the belt.

hand end thereof, as shown in Figure 1, a

A spring 21 connected with the frame 10 and the arm 18 normally holds the belt tightener pulley` 17 in such position'as to let the pulley wheel 12 run idle. ,A

On the shaft 11 is xed a geai` 22 which meshes with a gear 23on a shaft 24. On the shaft 24 is a gear 25 meshing with a gear 26 on the operating shaft or spindle 27. -f Y For mounting the coil Winder on the spindleor shaft 27, I provide what'for convenience may be called the spindle head 28. Equi-distantly spaced., rectangular bars 29 are received between their ends inthe spin# dle head 28 and are held in position by a detachable head plate 30.

` At one end ofthe bar 29, to-wit the right- U-shaped shaft journaling member 31 is secured to the bars 29 between their ends in any suitable way.

Between the bars 29 are shafts 32 arranged in 'alignment and having their adjacent ends received in the spindle head 28 as shown in VFigure 2. The right-hand shaft 32 has yat its outer end a reduc-ed portion 33, shown in Figure 1, extended through the journal 31 and provided on its outer end with a removable head 34. The right-hand shaft 32, as shown in Figure 1, is thus held against longitudinal movement with relation to the bars 29.

The left-hand shaft 32 is mounted for limitedV longitudinal movement for facilitating the removal of the coils after the windingY operation.

The outer end of the left-hand shaft 32 is shown inl Figure 8. It is provided with a reducedy spindle 35, which is longer than the spindle 33 above referred to.

Between the right hand ends of the bars 29V is mounted an H-shaped journal me1n-v ber36 (see Figures 1 and 8) through the central member of which vthe spindle 35 is extended. A short shaft 38 is rotatably mounted in the outer arms of the journal member 36 and has on it between said arms,

the eccentrically mounted cylinder 39.

On the outer end of the sha-ft 38v is the handle 40.

A loop or yoke 41 is received between the left-hand ends of the left-hand bars 29 and one end of the yoke 41 is `mounted in 'the right-hand portion of the spindle 35, as shown in Figure 8.

`The eccentric spindle 39 is so arranged that it may bear against the end of the spindle 35 andagainst the other end of the yoke 41.

On the spindle 35 between the central cross member of the journal member 36, indicated at 36a in Figure 8, and the righthand end of the yoke 41, is fixed a collar 42.

By manipulating the handle 40 and rotating the shaft 38, the eccentriecylinder 39 can be actuated for moving the yoke 41 and the left-hand shaft 32 longitudinally for thus Yvarying the position v.of the left- 38 adjacent to the handle 40 a collar -43 having the flat faces 44 and 45 and between them thecurved portion 46, as Ashown in Figur-e 9.

A flat spring 47 issecured to vone ofthe bars 29 for cooperating with the faces 44 and of the collar 4 Adjustably mounted on the bars 29 and' the shafts 32 on opposite sides ofthe spindle head 28` are the winding reels, which are similar except for the features herein after referred to. p

The windingreels are indicated generally by the reference characters A and B in the drawings.

Each winding reel consists of a cylindrical portion 48 withl a flange 49 adjacent to the bars 29. Each winding reel has an extension 50 angular Ain cross section proj-ected between the barsA 29 as shown'in Figure 4 and a terminal flange 51, as shown in said figure. Y

The shafts 32 are provided with flat faces 52. a

In the end of eachwinding reel, which has the flange 51, is mounted a` s et screw 53. Between each set screw'53 and one of the 'shafts 32 is an elongated wear and gripping plat-e 54, one face of which Vis flat and abutting against the flat face 52 of the shaft 32, and the other face of which is curved to lit the bore 55 in the extension 50 of the winding reel.

It will be understood that the shafts 32 are extended thro-ugh the bores 55.

In each wear and friction or binding plate 54 is a socket 56 to receive the end of the set screw so that the wear and friction plate 54 slides with thev set screw and the winding reel.v Y K These reels areadjustable longitudinally on the bars 29 and shafts 32 and may be.

locked or set in any posi ion of adjustment by means ofthe setvscrews 53.

Each cylindrical portion 48 of each winding coil has at its ends and opposite that provided with the flange 51 anl annular flange 57 having a flat face 58.

In the end of each `cylindrical port-ionV 48 opposite the set screw 53 isa bore or Y socket 59.

"I provide a' disc 60 for coacting Vwith the flange 57,so that the coils may be wound between the l'flanges 57 and the discs 60.

Each disc 60 has oppositely extending cylindrical members 61'and 62 of different diameters. The extensions '61 and 62 of l. i e

different diameters are provided for winding coils with different spaces between lthe wires.

)When the 'smaller extension-61 is insertedy into the bore 59, a bushing 63 isemployed, and when the larger extension 62 is inserted, f

the bushing 63 is removed. *The outwardly extending end serves asl a handle. n

non-rotatablyv mounted in the flange 57, as A `screw'81.

shown for instance in Figure 5.

T he cylinder 48 has a lateral-extension `466 in which is received a sleeve 67 mounted for rotation and internally screw-threaded. The lateral exten`sion166 (see Figures 2 and 5) has a removable cap 68, for convenience in assembling the parts.

rOn what may be called the outer end of' the sleeve 67 is.` a knurled flange 69 by the rotationof ,which the rod mayy be adjusted. V

It will be understood that th-einner end of the rod 65 is screw-threaded as at'70 and screwed into the sleeve 67. f

For locking theknurled flange ing bolt or the like 71 v(see Figures 5 and 6). One end of the bolt 71, as kat 72, is threaded to be received and tocoact with a threaded socket 73. Intermediate of its ends the bolt 71 is cylindrical, as shown, except that it has a flattened face 74. Whenthe flat face 74 is adjacent to the flange 69, the flange 69 can rotate freely, but when the bolt 71 is rotated by means of the handle.`72

thereon (see Figures 2, 5 and-6),.saidboltv of the bolt 65, whereupon the set screw 64 (see Figures 4 and 5) is moved tolocking position. Y l

rEhe end of the. right-hand winding reel, as shown inFigures 1 and 2, is provided with a slot 75 adjacent to the bore 59.

1t should perhaps be notedv that the bushing 68 is provided with a hole 76A in its wall to receive the'set screw 64, as shown in Figure 4, and is provided with a' slot 7 7' atone 69 againstv rotation, I mount in the cylinder 48 a locli end which registers with the slot 75 when the bushing is installed. The slot 75 eX- tendsacross the end of the cylinder 48 and across the flange 57 parallel with. the. rods 29.

The windingreels' are the same as heretotoro described, except that thek left-hand vwindingreel does not havethe slot 75'v nor the slot 77 in its bushing 63.

I will now describe the means for engag- 1 ingv and'holding the end' or ends of the wire being wound,wh1ch forni the leads.

A rod 78 is slidably extended throughthe cylindrical body 48 and is locked in its various adjusted positions by means ot va set screw 79. (See Figures 2oand 4.) Slidably adjusted' on the'outer end of the rod 78 is ali-lock 80, which may be locked in various positions of its adjustment A U-shaped support 82 has one yarm shorter than the other as shown 1n Figure 7. The short arm 1s pivotally mounted by means of .a headed stud 88 onr the `block 89 in such manner that the support 82 may rotate on the stud 83, the axis ofwhich is at right angles to that of the rod 7 8l On the longer arm of the support-'80, an

eccentric camv 84 is rotatabl-ymounted on a` stud 85.` The cam 84 has the controlling handle 86, shown in Figure 2.

VIt may be mentionedv at this time that the support'82 has a handle 87 for more con- (See Figure 2.) f

veniently manipulating it.

'A clamping jaw 88 is mounted on a bolt 89, whichv is threaded into la lug 90 on the longer arm of the support 82, as shown in Figure 7, whereby the clamping jaw 88 may be`v adjusted-toward or from the eccentric cam 84.

The slot 75 in the cylindrical body 48 of the right-hand winding reel yshown in Figures 1, 2 and 3 is designed to receive the leads or ends of a wire or wires 91. In order to prevent the lead from slipping out ot' the slot 75 toward the disc 60 after the lead has once vbeenreceived in the slot 75, Ivprovide the following means:

An arm 92 is pivoted at 93 in the flange 49. (See Figure A spring 94 tends to by a set lll-3 llo hold the free end of the arm from the *I cylindrical body 48.

' I provide a slot closing member comprising a cylindrical bodyk 95, Vhaving a beveled face 96 and having at its end opposite the beveled facean ear 97 pivoted as at 98 to the free end'of thearm 92. Y

The end of the. 'cylindrical body 95 forms l right angles to it.

portion of the cylindrical body 95 into the outer part 'otA the slot 75 and thus closing it for holding the wire 91 in it, I provide the lollowing'means: Y

0n the .right-hand winding reel. cylindrical portion 48 is a pair ol' projecting ears 99. (See Figures 1 and4.) Journaled in these ears ashort shatt 100 on which is a. Cam 101. A U-shaped arm 102 is Vconnected with the cam 101 and has at its free end a handle 103 extending away from it at The ifreeend of the U- shaped arm 102 stands adjacent to the tree end oit the arm when that arm. is at the limit ot its movenjient away from the cylindrical portion 48, as shown in Figure 4.

Mounted'on the armv92 between it and the eccentric cam 101 is a plate 104, which has an elongated slot 105. The plate 104 is fastened to the arm 92 by means ot a screw bolt 106 extended througlithe slot 105 into the arm 92. The plate 104 has a beveled face 107 for coaeting with the cam 101.

improved coil winder and in connection with that description-will explain more fully the structure of the device.

The wire 91 is wound into a reel 91" on a suitable drum 108 supported on a shat't 109, which is journaled in a suitable trame 110. A tlat, flexible, metal strap 111 or itsy the bores 76. According to the width de-v sired for the space 113 between the opposite sides ot' the coil, the operator uses thecxtensionsl 61 or 62. vllffthe extension 61 used, the bushing G8 is employed.

The space between the disc and flange 57 is adjusted according to the thickness of the coil desired. rlhis is done by adjusting the bolt by means oit the sleeve 67 and knurled flanger 69 (see ,Figure 5),.and the locking oft the bolt 65 by means ot the lockingl bolt 71. (See Figures 5 and 6.)

The winding` reels are adjusted on the bars 29 vby loosening the set screws 53 and adjusting theY winding reels longitudinally olf the bars. One o't each otI the bars is graduated as indicated at 114 (see Figure 2) and the flanges 51 are each provided with two lpointer lingers 115, which are spaced 'from each other corresponding to the ditl'erence in diameter ot the respective extensions 62 and 61. Y

rlhe winding reels are then locked in position by means of Vthe set screws 53. rlhis adjustment of the winding Vreels determines the length of the finished coil 116.

I will now describe the operation ol my The rod 78. is then adjustedrin its cylin-l drical Vbody 48 and locked in Vposition by means of theV set screw .79 according-v to the length of the lead 117 (Figure 12) that may be desired.

Thewinder is then Iswung around until the ri ght-hand end thereof shown in Figures 1 and 2 is adjacent the reel 91a, and the ends of the wire or wires are clamped between the jaw 88 and the cam 84. The jawv 88 is adjusted according to the diameter of` revolution to the position shown in Figure .Y

3, the operator pushes the wire 91 toward the winder. r1`he wire will slide down over the U-shaped arm 102 into the space between the disc 60 and the flange 57 (see Figure 4).

1t will be ren'ielnbered that when Jthe halt' revolution ot the Winder has taken place, the slot 75 will be up. and on account-of the tact that the operator has pushed the wire 91 toward the Winder, the wire will slip into the slot as shown in Figure 4.

.The operator then quickly graspsthe hani dle member 103 and swings the U-shaped arm 102 from its. position shown'in :t'ull lines in `Figures 3 and 4to its position shown in dotted lines in saidiigures'.

- The Cam 101 will'engage'the beveled Vface 107 of the plate 104 andrt'orce the arm 92 toward the cylindrical body 48 for moving the cylindrical member to position `for closing the slot 7 5, asshown by dotted lines in Figure 4, vand ypreventing the leadirom sliding into the space between the Vflange 57 and the disc 60. i

As .the rotation ot Vthe winder continuesk coil by loosening theset screws 64. He then swings the handle 40- around (see Figures 1 and 2) for rotating the veccentric 39 from its full line position shownV in Figure 8 toward its dotted line position shown in said ligure, whereuponV the left-hand rod 32`shown in Figure 1 will be moved longitudinally toward the right, carrying with it the yoke 41 for loosening'the coil on the extension 61 or 62 as the case may be.

The projecting extensions 61 or 62 may be grasped for removing the discs v(SO and taking olf the finished coil. The discs 6() are then replaced in position and-another coil can be Wound.

A great advantage inthe present device arises from the speed with which it may be operated for Winding the coils. The convenience in manipulating the parts contributes, of course, to such speed.`

It Will benoted in the form of the device heretofore described, the Winding reels are adjustedv slidably on the bars 29 and rods or shafts 32. l

In lFigures 10 and 11, I have shown Aa slightly dierent Way of adjusting the winding reels toward or from each other. This form of my invention is Valso provided with the means illustrated in Figures 8 and 9 for releasingthe tension on the Wound coil by moving left hand spool 48 toward the center.

The shafts 32a are threadedfas at 118 for a considerable portion of their length. One of the shafts is provided'ivith a slot. 119 and Ythe other with a tongue 120 slidable in said slot and the shafts are arranged Withtheir ends having such slot and tongue 'received in the spindle head 28.

The cylindrical bodies i8 of the Winding ll Areels have threaded portions 121 receiving the threaded portions 118 of the shafts 32. On the ends of the shafts are crank handles 122, so that by rotating the shafts, the Winding reels may bemoved toward orfrom each other. j It Will be understood that the shafts are provided respectively with right-hand and leftliand screw threads. v Y The left-hand shaft 32a is bodily movable lengthwise in the same manner as the lefthand shaft 82 shown in Figure 1j.

Some changes may be made in the arrangement and construction of the various parts ofmy coil Winder, Without Vdeparting from the real spirit and purpose of my invention, and-it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents, Which may be rea sonably included Within their scope.
