MACHINE FOR WINDING WIRE.

To all whom 'it may concern:

Be it known that I, CHARLES E. FETHER- our, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Machines for lVinding Wire, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to machines for winding wire on a form or core.

It has for its object to produce a machine adapted to accurately and uniformly wind coils of wire, and to provide mechanism for properly guiding and feeding wire of different sizes to the article to be wound.

Figure 1 is a top plan view of a machine embodying my invention. Fig. 2 is a side elevation. Fig. 3 is a side view of a form or core to be wound.

In the drawings A represents the base of the machine suitably supported on standards or upright-s B.

Arranged on the baseA is a shaft 2 mounted in' bearings 2, 2". Carried on this shaft and preferably centrally thereof is a fixed pulley 3 with which. a belt 4, connected with a source of power, engages and is adapted to impart rotation to the shaft. Secured to one end of the shaft is an enlarged head or face plate 5. The form or core C to be wound is secured to this plate by bolts 5, 5 which extend loosely through slots 0, c in the form and are secured to the face plate j v 3 clutch 14 IS a lever 15 the outer end of by means of screw threads.

5, 5 are springs interposed between the core and the heads of the bolts and adapted to hold it against the face plate 5.

()n the other end of the shaft opposite to the. form C is fixedly secured a combined friction and brake wheel 6 arranged to be engaged by a brake band 7. The brake band is secured at one end 7 a to thebase A and its opposite end extends through a hole in the base and is secured to a-lever 8 fulcrumed at 8,-the outer end of which is controlled by a rod 9 extending downward therefrom and pivotally attached at its lower end to a pedal 10 fixed to a shaft. 11 mounted in the standards B. Arranged between one ofthe cross members of the upright B and the pedal 10 is a spring12 which operates, through the pedal 10,rod 9, and lever 8 to hold. the brake Specification of Letters Patent.

band normally in engagement with the brake wheel.

13 represents a rod fixed to the shaft 11 and movable therewith. It extends upward and has its free end curved or bent inward at 13.

13 is an anti-friction pulley secured to the free end of the rod 13 and adapted to be swung therewith and to engage the belt 1 and thereby tighten the same to cause it to gripthe pulley 32 When the pedal 10 is depressed the brake band is simultaneously released, and the rod 13 moves into theposition shown in dotted lines in Fig. 2 tightening the belt 4 whereby power is transmitted to drive the shaft 2.

The feeding and guiding device for thc wire comprises a traveling carriage '14, mounted on a pair of screw threaded shafts 15 arranged parallel to each other and themselves suitably mounted in bearings in the brackets 16. 16 on the frame. The screw threaded shafts 15, 15 are provided at one end with spur gears 15, 15 which mesh with each other and when drivencause the shafts to rotate in opposite directions. The carriage 14 is provided with screw threaded means, prcferablya double acting clutch as indicated at 14 arranged alternately to engage one of the shafts 15 and to move thereon longitudinally in one direction relative to the form or core. C. Pivotally mounted in the carriage and connected with the said screw threaded means or double acting which engages with stops 17. The stops 17 are mounted on the rod 17 which is carried by the standards 26 and are adapted to shift the lever 15 to cause it to operate the double acting clutch 14: and change the direction of travel of the carriage- As indicated these stops 17 are adjustable longitudinally of the screw threaded rods 15 to vary the travel of the carriage and accommodate it to the winding of various lengths of cores or forms.

Mounted on the carriage 14 is a sliding block 18 provided with two rollers 18*, one

above the other and preferably out of axial which the guide rollers are attached is mounted in guides 18 on the carriage and is adjustable longitudinally therein by means of the thumb screw 19 suitably mounted in the carriage and connected to the block 18. Mounted in bearings in brackets a, a at the opposite end of the base A from the form C is a transverse shaft 20 arranged transversely and preferably at right angles to and in the same plane with the shaft 2.

21 is a friction pinion or pulley mounted to slide longitudinally of the shaft 20 to which it is keyed or s lined. It is normally held yieldingly in rictional engagement with the outside friction face of the friction and brake wheel 6 by means of the spring 21*, which bears against the end 21 of the shaft 20. At the opposite end of the shaft 20 is secured a bevel gear 20 which meshes with a bevel gear 20 secured to a shaft 22 the latter being mounted in suitable bearing; in the arm a of the adjacent brackets a. otion isimparted to the screw threaded shafts 15, 15 by means of a longitudinally adjustable driving shaft 23. This shaft 23 is formed of two ieces 23, 23 one of which 23, is hollow so at the other piece 23 may slide into it like a telescope. parts is keyed or splined and the other grooved to form a slidable connection between the parts which will cause them to rotate together when either one is rotated. The free end of the hollow rod 23 is connected by a universal joint 23 to one of the threaded shafts 15. The free end of the rod 23 is connected by a universal joint 23 with the inner end of the shaft 22.

In order to feed the wire to the core and to cause the carriage to reciprocate longitudinally relatively to the core fast or slow according to the size of the wire to be wound thereon, I provide means for ad'usting the pinion 21 on the shaft 20 radially along the face of the friction and brake wheel 6 relatively to the axis of the shaft 2. These means comprise a countershaft 24 mounted in suitable bearin s in the brackets a, a, which shaft is rotated y a crank wheel 24*. This shaft 241- is screw threaded for a portion of its length and has mounted on it an internally threaded sleeve or nut 24*. To the sleeve or nut 24 -is secured a rod 25 which e ages with the pinion 21 by means of forke arms or any suitable manner and is adapted to move the said friction pinion along the shaft 24.

25 is a scale arranged adjacent to and parallel to the shaft 24, and 25' is anindicator carried by the rod 25 and adapted to indicate the ratio of reduction between ,the core or form on the shaft 2 and the travel of the carriage 14 feeding onto the core or frame a layer of wire of a given size.

The reciprocating carriage 14 is adjust- One of these able toward and from the core or form C as may be desired according to the size of the core to be wound. F or this purpose I provide in the base A two grooves 26, 26 arrangedparallel to each other. The standards 16, 16, in which the screw threaded shafts 15, 15 are mounted, are arranged to slide in these grooves and are held therein in their adjusted positions in any suitable manner. As shown in dotted lines in Fig. 1 when the carriage and its operating mechan sm are adjusted in the grooves 26, the telescoping rod 23 is accordingly lengthened or shortened as the case may be, the universal joints connecting it with the shafts 15 and 22 and permitting it'to accommodate itself to any position of the feeding and guiding mechanism.

When the end of the wire that is to be wound on the form or core C is attached thereto it is desirable to feed the wire to the core at an angle relatively to its axis of rotation during the winding of the firstlayer. In order that the coil may be properly started and to prevent the wire from piling up I prefer to adjust the core C on the face p ate 5 into an angular position relatively to the axis of rotation of the shaft 2.' I provide the face 5 with screws 5 the inner ends of which bear'against the inner face of the core. When one-of the screws 5' is turned the core is forced outward on that side, the slots 0 being elongated as shown in Fig. 3 to permit this adjustment of the core. When the screw 5 is turned back, the sprin 5' bearing against the head of the bolt 5 an the outer face of the core 0 forces the latter into its normal position against the face plate 5. I prefer to provide the face plate with two or more adjusting screws so that the core may be adjusted from either side according .to the side of the core to which the end of the wire'is attached.

It is often necessary to wind forms or cores rectangular or irregular in cross sec tion. With a core of this description a short or narrow side will take off less wire from the reel than will a long side,and as the core swings. or rotates exposing first one side and then the other there is an alternate tendency to slack the wire and then to jerk it. 'In order to keep the wireunder these circumstances at a substantially uniform tension I provide between the wire reel E and the carriage 14: a tension device which is indicated as an entirety by D. It consists of a suspension bracket 27 to which is pivotallyconnected a swinging arm 28, carrying at its free end a roller 29' over which. the wire to be wound is carried.

30 is a spring secured at its lower end to the free end of the arm 28 and at its upper end to some stationary support above the arm. It is adapted to normally pull the tension of the wire will remainpractically' the same.

In operation a core to be wound is placed upon the bolts 5, 5 on the core carrying plate 5 and the wire to be wound upon the core is led from the reel E over the roller 29 between the rolls 18, 18?, on the carriage 14 and thence to the core C, its end being in-.

sorted through one side wall of the core, or secured to the core in any suitable manner. The hand wheel 24 is then operated to set the friction pulley 21 at the desired point of engagement with the friction face of the wheel 6 to give as indicated by the index 25 the proper ratio'of speed reduction between the core C vand the threaded carriage feed shafts 15,15 for the size of wire tobe wound upon the core. If the wire is either over or under the standard size, indicated by the index at 25, for which the machine is adjusted, a slight turn of the hand wheel 24* in the required direction will correct the machine to the wire being used. If, however, the wire varies, first being larger-and then smaller ii diameter, and so on for short intervals, t ese irregularities can be compensated for on each layer of wire wound upon the core by independent adjustment of the block 18 by means of the thumbscrew 19. Again,- when winding very fine wire, the rollers 18 18 on the carriage 14 may not directthe wire in an exact line to its desired position 9n the form, thereby making it pile.

up or not lay up close, and this too may be remedied by adjusting the thumb screw 19 either right or left, which will change the position of the wire relative to the carriage the amount necessary to give the proper result. When winding onto the core the first layer of wire, it is desirable to lay it on at an angle to the axis of the core in order to prevent its piling up along one side of the core instead of being spread over the same in a layer of uniform thickness and uniformity. To start the winding of a core, and also to prevent piling up of the wire at the sides of the core, the core may be bodily adjusted by means of the set screws 5 5". For example if one of these set screws is turned to push the form away from the face plate against the pressure of the spring 5' substantially out the necessary degree, preferably about half the width of the wire or a little more, and the machine is started and a layer of wire wound on at the given angle. Then when the carriage 14 starts back in the opposite direction to feed the wire for the next layer, the set screw 5 which has been used to throw out the core may be adjusted toits normal position and the corethrown out to another angle by adjusting the other set screw 5 as desired.

It will thus be seen that I have provided a mechanism capable of a wide range of adjustments to suit it for the winding of various sizes and shapes of cores and different sizes of wire, and one furthermore which may be quickly and readily adjusted to accom-modate it to the winding of wire either over or above size and also capable of quick adjustment to vary the angle at which each layer of wire is laid up relative to the axis of the core.
