To all whom it may concern:

Be it known that I, JOHN JANIoKI, "a citizen of the United States, residing at Oak Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Methods of and Apparatus for Serving Material upon a Core,

of which the following is a lull, clearyconk .cise, and exact description.

This invention relates to methodsof and apparatus for serving material upon a core, and. more particularly to a method "of and apparatus for simultaneously serving a plurality of strands upon a core. Y

In insulating wire for electrical purposes it is frequently thepractice' to'serve the wire core with a plurality of strands of silk, cotton, or other'insul ati'ng materials, which to expedite the serving operation have been assembled into a band or a composite or multi-end strand and wound into a cop. The individual strands,whic h may be-different'ly colored to comprise an identifying covering for the wire, are arranged toform a single layer as they are served'u'pon the core. 'It has been proposed'in one instance, that these strands be separated or fannedalong the axis of the core and served thereon from a commonline disposed radially'with respect to the core. However, it hasbeen found that only a limited number of strands may be satisfactorily and uniformly served in a .simultaneous manner by such amethod. I V

The objects of the invention are to provide an improved method of and an improved apparatus for rapidly and uniformly serving an unlimited number of strands upon a core.

In order; to attain this object in accordance with one embodiment of this invention, a plurality of strands are withdrawn irom a cop or other supply toa common point, or a multi-end strand is drawn thereto, which point is located at a distance from r the periphery of a core to be served. The

strands or the ends composing the multi-end strand, are fanned from the common point p to a plurality of non-uniformlyspaced points so distributed 'as' to 'mainta inthem separated. They are individua lly' guided therefrom to a corresponding numberfof points uniformly spaced "around core and then served to .theeore at substantially eqae 'aagles to iQrl $l! aii ih In one embodiment of the invention in. an

apparatus byime'ans of which the method may be practiced, a. serv ng mechanism of a usual type wherein a core is drawnvertically through the axisof a horizontally rotating holder and serving head from which the strands are-served, is provided with a distributing head or plate secured to the The distributing plate is prov ded w th 'a plurality of slotted apertures, the bottom or inle-t ends of which are non-uniformly spaced. to maintain the,

strands fed from a common point separated from each other and from the serving head, while the upper or outlet ends of theaipertures are uniformly spaced aroundlthe core.

i'lhe rotat ion ofthehead serves the strands from the outletends of the apertures at substantially equalangles to'the core.

Other objects and advantages of this invention will more fully appear from the accompanying detailed description taken in connection with the accompanying drawings which illustrate one embodiment thereof, in vhi Figfl fis 'afvertical sectional view partly .in elevation through a serving head embodying the features of this invention FigLjQis a plan View thereof;

"The'tiibefifl is secured provide a desired tension upon the strands 19 during the operation of the serving mechanism.

Y The extreme threaded upper end of the spindle extends above the top of the rim 11 and is tapered, as indicated at 27 and provided with a plurality of slots, one of which is shown at 23, extending downwardly from the end thereof. Adapted to be mounted upon the hollow spindle is a unitary multi-strand guiding device 29, a sleevelike portion 30 at the lower end thereof being being inserted in thebore of the hollow spindle and clamped thereto by turning a threaded collar 31 downwardly upon the tapered end of the spindle 15. The upper end of the device 29v comprises a circular shaped head or plate 32 provided at its underside with a cone-like. face'33 extending from the peripheral edge thereof to the periphery of the sleeve-like portion 30. The upper face of the head 32 is also provided with a cone-like face 34 whiclrextends from a point inside the peripheral edge of the head 32 to the wall of the bore formed in the device 29. The purpose of the cone-like faces 33 and34 will be made clear as the description progresses. The head 32 is provided in the present embodiment of this invention with seven angularly-disposed apertures 37 one for each of the strands 19, which apertures at their outlet ends upon the upper surface of the head 32, are equally disposed, radially and circumferentially with respect to a core 38 beingserved which serves to direct each strand to a certain predetermined point upon the periphery of the core 38. The apertures 37. are formed at such an angle to the axis of the device and to each other that the inlet ends of the apertures are not equally disposed radially and circumferentially. -Theangle of each aperture is such that each strand 19 will be guided in passing from the opening 12 in the rim 11 to its respective aperture 37 and upwardly therethrough and to the core 38 being served without engaging any other strand during its travel. Also the-strands are guided so that they will not contact with the periphery of the sleeve-like portion 30 and due to the cone-like faces 33 and34, the guiding surface-of the apertures is .reduced and consequently friction upon the strands is reduced to a minimum. 'lof acili- 19 within an aperture 37 in threading the serving mechanism by merely pressing the strand against the periphery of the head 32 between the slots 40 and slide it toward the cut back portion 41 which will cause it to ride into the slot 40 and therealong intothe aperture 37.

It will be observed that the diameter of the device 29 is such that a cop 14 of serving material may be mounted on the serving mechanism without removing the device, the diameter being such that the tube 20 carrying the cop 14 may pass freely thereover.

Referring to Figs. 1, 3 and 4 it will be noted that the strands 19 in passing-from the opening 13 in the rim 11 to the core 38 do not engage each other or any portion of the guiding device 29 except the walls of the apertures 37 and their engagementtherewith is reduced to a inininiuin due to the cone-like face 33 at the underside of the guide 29 which serves to reduce the length of the apertures and consequently friction upon the strands. After the strands 19 leave the apertures 37 there occurs a point contact of the strands with the upper peripheral edge of the cone-like face 34 which with the uniform radial and circumferential spacing of the outlet ends of the apertures 37 about the core 38 serves to support and cause the strands to approach the periphery of the core atuniform angles and laid thereon parallel to each other.

The operation of the serving mechanism hereinbefore described is as follows:

The core 38 being served, it will be understood, is drawn through the hollow driving spindle 15 and guiding device 29 by any suitable drawing off mechanism which will insure an even steady movement bearing a substantially fixed relation to the speed of rotation of-the driving spindle and the diameter of the strand being served to the core. Drawing off mechanisms of this type being well understood in the art, no attempt hasbeen made to show the same. Upon mounting the cop 14 upon the sleeve 16 in the manner hereinbefore described the end of the multi-end cotton strand 18 is threaded through the

openings

12 and 13 in the rim- 11 as clearly shown in Fig. 1. Upon leaving the opening 13 it will be readily apparentthat the ends 19 of the strand 18' willbe separately guided to the core 38 by their passage through the apertures 37 of the device and as hereinbefore explained lOJ ' guiding a plurality of strands from a com due to the uniform radial and circumferential spacing of the outlet ends of the apertures 37 about the core 38 they will be served with a minimum amount of friction and laid parallel thereon with a uniform twist or lay.

A strand guiding device embodying the features of this invention provides for accurate control of the spacing between the strands as they are served to the coretherc by preventing open spaces therebetween and,

piling up of one strand upon another.
