y 11y claims. (c1. 117-34) This invention relates to improvements inmachines for uniting a plurality of elements or serving covering elements about a core element.

The principal objects of the invention are directed to the provision in a machine for uniting elements or for; serving or covering a core element with other elements of means wherein the elements are suitably guided and tensioned for the uniting or covering operation. Various novel features and advantages of the invention will be more fully hereinafter referredy to in connection with the accompanying description of the novel combination and arrangement of parts constituting the invention, reference being had to the accompanying drawing wherein;

Fig. 1 is an elevational view of an apparatus of the class described having the novel features of the invention associated therewith.

Fig. 2 is a partialsectional view at a larger scale showing certain novel features of the invention,

and

Fig. 3 is a fragmentary elevational view to explain certain features of the invention.

. Referring now to the drawing more in detail the novel features of the invention will be fully described.

In Fig. 1 there is shown an apparatus which may consist of one or more'spindle units indi-4 cated by 2 and 4. In the form of the invention at present preferred two spindles are shown, one above the other and they may be used to serve an outer element or elements about an inner core element as will appear, but it will be understood the apparatus may be used to unite by twisting or throwing a number of elements.

Each of the spindle units. preferably lincludes a rotatable spindle 6 which spindle in the form of the invention shown may be associated with a'rotating part of a motor enclosed within a housing 8 which is suitably supported by frame 10. A v take-up member 12 which may be in the form of a spool or drum is rotatable above the spindles and a transversely reciprocating bar 14 as in the said application is provided for leading the nished product onto the take-up member. Guides 16 having openings 17 therethrough are suitably supported by supporting structures 18 shown extending from the frame 10. y

The spindles 6 referred to are preferably hol- 'low to permit material such as a core element y C to pass therethrough and have portions on` their upper ends to receive spools or packages represented by S. These spools or packages may have wound thereon yan1. filaments or other ele- Y spindle.

ments indicated by E, and will be called yarn packages.

A guide cap indicated generally by 20 is provided for each spindle and will be described in detail to facilitate a clear understanding of the novel features thereof. yThe cap has a body portion having a central hub portion 22 as shown which is suitably bored to t and receive the upper end 6' of the spindlevand is hollowed out as at 24 so thatits lower end 25 isA in the form 65 of a skirt or flange to encircle the upper end of the yarn package S.

Annular guideways

28, 30, 32, and 34 disposed one above the other are provided on the cap and decrease in diameter' upwardly from the lower one. Travelers t which maybe more or less circular in shape as shown in Fig. 3 are slidable around the annular guideways. The cap is removable from the `spindle to permit packages to be placed on and taken off the To facilitate aclear understanding of the operaltion of the cap it will be assumed that a core C in the form of a yarn or filament of metal or rubber is being passed upwardly through the spindles 6 and onto the take-up spool and that 80 it is desired to cover or serve the core with covering elements or filamentsdwhich may be carried by the yarn packages. The filaments from the packages are passed upwardly through the travelers t and onto the core C. With the spindles in rotation the lpackages S will be rotated as will the caps 20 so that the elements will be carried around and wound or served about the core. As will be seen with particular reference to Fig. 3 an element E is guided at'spaced intervals from a point adjacent the upper end of the spool to anupper point adjacent where it passes onto the core whereby the element is held against ballooning.

A cap rotates with its spindle so that theA relative movementsbetween the travelers and the guideways therefore is not great, at least only enough to allow the core to take up the element, or allow the element to be wound-about the core. Therefore appreciable frictional. action between the travelers and the guideways is eliminated as distinguished from the condition where a trav' eler slides around a non-rotating guideway. This is all to the end that a very delicate element may be wound onto the core without 4being burdened with excess tension and makes it possible to Wind an element about the core with the desired degree of tension and uniformity and without such over tension as will either cause the elebear. As shown in Fig. 3 as a somewhat ilat filavwill strain the laments about the core a-guiding horn 39 is.

provided at the upper side ofthe cap which has a rounded end or rounded circumferential ironing surface y41 against `which the filament may ment travels around the edge 41 and upwardly onto the core it is flattened out or turned so that it is guided in lproper position and without twisting as it passes onto the core.

It may be desirable in some cases to provide packages with a multiplicity of separate elements or ends wound thereon. In such'a case one of the elements may be passed upwardly. through one or more of the travelers t while another element may be passed upwardly through one or more of the other travelers t all to the end that one end or filament may be guided independently pf another and onto the core, each with the propery tension and in the manner desired, held against ballooning. i

As will be seen an element E is taken on by *the core C at a pointbetween the lower end of the guide 16 and the upper end of the cap 20 and the uppermost traveler operates to guide an element in close proximity to the point where the elementand core are united. The element between the upper and lower travelers is held..

vide the lubrication therefore.

In some cases it may be desired instead of covering a central core element with a covering element to twist or throw an element from one spool with an element of another spool or to twist elements of either spool with one or more of those of another spool.l This may be accomplished by bringing the elements together above the cap and passing them through the travelers. l

From the foregoing, it will be apparent that the apparatus is adapted to insure accuracy and excellence of product in connection with operations where it is desired to unite elements of various materials. It is desired therefore to be limited, if at all, by the appended claims rather than by the foregoing description. What I desire to claim and secure by Letters Patent of the United States is:
