machines and more. particularly to fliers having a pivoted or folding flier wire.

Covering machines for winding yarn about a central core or strand as constructed heretofore are frequently provided with a flier disposed above the package that supplies the covering yarn. The flier rotates with such package to guide and tension the yarn as it passes from the rotating package to the core about which it is wound as a spiral cover. These fliers usually consist of a thin flat body having a spindle receiving opening therethrough and a flier wire secured to such body and extending outwardly some distance beyond the diameter of the full package, so that the flier will hold the yarn substantially clear of the package as it is unwound therefrom and wound about the core a short distance above the package. In some of these prior constructions the flier wire is rigidly secured to.

the flier body, and when this type of flier is used it is necessary to remove the flier-from its operating position before the package can be doffed.

In order to avoid the necessity of removing the flier when the package is to be dofied it has been proposed heretofore to employ a flier comprising a flat body having a flierwire pivotally secured This invention relates to fliers for covering 7 2 ally secured to the flier body so that it can be swung inwardly towards the body to lie out of the way of the package when the latter is to be doffed; to provide a flier which is easy to thread up due to a shoulder construction that limits the swinging movement of the flier wire; to provide a flier which is largely self-cleaning thereby to v keep it free of lint; and to provide a flier which tion has a flat flier body that is conveniently thereto so that this wire may be swung inwardly with a folding movement to lie against a face of such body where it will be out of the way of the package that is being placed on or removed from the package supporting spindle.

While the type of flier just described as having a pivoted flier wire permits this wire to be folded inwardly out 'of the way when the package is toj be dofied, it is more difiicult to thread ufthanthe first mentioned type of flier consistingof a flat'body having the flier wire rigidly secured thereto. This is due to the fact that if the flier wire is pivotally secured to its flier body so that it can swing freely back and forth through a large arc, it is necessary in threading up the flier for the operator to use one hand to hold the wire in a fixed position while the covering yarn is being engaged by the other hand with the coiled loop at the outer end of the flier wire.

The present invention contemplates a flier comprising a flat flier body having a flier wire pivotally secured thereto for swinging movements, but which'is so constructed that it is as easy to thread up as the prior type of flier having a body with the flier wire rigidly secured thereto, and the present flier possesses other advantages to be described.

'The present invention seeks to provide a flier for covering machines havinga flier wire pivotformed by cutting the same from a fiber sheet. The advantages of a fiber body are that it will not wear the metal parts it engages when in operation upon a covering machine and it will not be worn appreciably by its engagement with such is desired to tension the yarn being wrapped about the core. Such fiber body is provided near its center with a spindle receiving opening, and to an outer peripheral portion of this flier body is'pivotally secured a flier wire. The arrangement is such that this wire may be swung or folded inwardly to lie against a flat face of the flier body where it will be out of the way when .the package is being dofled, and it can be swung outwardly by hand or by centrifugal force to its thread guiding position.

An extremely important feature of the present invention resides in a shoulder or stop provided upon the flier body whereby the outward swinging movement of the fiier wire will be arrested near the fully open position of such wire. One advantage of this shoulder is that it acts as a stop against which the wire may rest when pressure is being exerted against this wire by the yarn during the manual threading up operation. This makes it unnecessary for the operator to hold the wire with his fingers during the threading up operation. The shoulder is preferably so positioned that it will stop the wire before it reaches its fully open position; that is the position which such wire would occupy if it were free to move to its fully opened position under its centrifugal force. By thus retaining the flier Wire at a slight angle to its fully open position during the covering operation the act on of centrifugal force upon the fiber particles at high speed is such that they tend to move at an angle to the wire. This has a desirable self-cleaning action upon the wire to remove the fibers therefrom.

The above and other features of the flier of the present invention will be further understood from the following description when read in connection with the accompanying drawing; wherein,

Fig. 1 is a side elevation of a covering machine unit comprising a rotating spindle and covering package provided with a flier constructed in accordance with the present invention.

Fig. 2 is a top plan view of the parts shown in Fig. 1.

Fig. 3 is a plan view showing the opposite face of the flier from that seen in Fig. 2; and

Fig. 4 is an enlarged view of the outer end portion of the flier wire as shown in Fig. l.

The flier contemplated by the present invention may be employed with various types of covering machines, and is shown in the drawing as employed upon a covering unit comprising a hollow spindle post III which is rotatably mounted in a well known manner and is adapted to be rotated by a whorl II. The spindle post is provided near its lower end with a bottom flange I2 upon which may rest the lower end of a paper tube [3 having wound thereupon the yarn package Mounted at the upper end of the tube I3 and package It is a cap IS the outer diameter of which is larger than that of the full package as shown. The hollow spindle post III has extending upwardly therefrom the spindle tube 16. The arrangement is such that the core C which may be a rubber thread. textile thread or wire extends upwardly through the hollow post and tube as shown, and during the covering operation this core moves upwardly at a uniform speed.

The parts so far described by reference characters form no essential part of the present invention but constitute one good form of covering apparatus with which the flier of the present invention may be used satisfactorily. The flier of the present invention comprises a flier body I1 having pivotally secured thereto the flier wire I8. The flier body, as above stated, is preferably formed by cutting the same from a sheet of flber which may be two or three hundredths of an inch thick. This body I! as shown in the drawing is longer than it is wide and has its ends rounded, and is provided near its center with an opening I9 adapted to flt around the spindle post I0 and rest upon the larger spindle shoulder disposed above the upper face of the cap I5 as shown in Fig. 1. After the flier has been placed in the operating position in which it is shown in Fig. 1 a cap 2I is pressed downwardly into snug engagement with the tube I6 to thereby prevent the flier from riding upwardly oif of the spindle post II) when the covering machine is in operation. The flier wire I8 is pivotally secured to the flier body I! near one end thereof for movement to and from a folded position, and its movement outwardly towards a fully open position is arrested by a shoulder 22 formed on the carrier body at one end of the arcuate portion 23 of the body, and the other end of this arcuate portion terminates in the notch 21. The arrangement is such that the wire I8 maybe moved to a folded position in which it lies against one face of the body I1 as indicated in-dotted lines in Fig. 3, or it may be swung outwardly until it strikes the shoulder 22 and lies in the position indicated by the dot and dash line marked a: on the drawing. This line a: it will be noted forms an acute angle with a second dot and dash line 2 that passes through the center of the opening I8 and the center of the hole 25 formed in the body I! and in which the wire I8 swings as a pivot.

During the core covering operation the rotating post III and yarn package It turn in the direction indicated by the arrow in Fig. 1 and in Fig. 2 and the yarn carried by the package I4 is so wound thereupon that the direction of rotation will tend to hold the yarn against the package. upwardly through the wire loop 26 disposed at the outer end of the wire l8, and as will be apparent from Fig. 4 the coils of this loop are spaced one from the other an appreciable distance so that the fibers that escape from the yarn will notbe likely to catch in the coils andcling thereto.

The flier shown may be so placed upon the spindle post II) that when the wire I8 is folded inwardly it will rest upon the upper face of the flier body as is the case in Figs. 1 and 2 if this wire should be folded inwardly, or the flier may be turned over so that when the wire I8 is folded inwardly it will lie against the under face of the carrier I! as shown in dot and dash lines in Fig. 3. It is important that the flier be so positioned upon the post I0 that during the normal rotation of the spindle centrifugal force will hold the wire I8 against the shoulder 22. In threading up the flier wire I8 it is merely necessary to press the yarn against a side of the wire I8 to hold this wire against the shoulder 22 and revolve the yarn in an arc of a circle to cause it to pass over the outer end of the coil 26 and into the centers of the coil as shown in Fig. 1, whereupon the power may be applied to rotate the whorl II and start the winding operation.

The wire I8 is secured to the body I! by a looped portion that passes through the hole 25 and its end is twisted around the wire I8 as at 21'. This provides a portion that strikes against the stop or shoulder 22. The slight friction that exists between the wire I8 and fiber body I! helps to retain the wire in the folded position when the package is being doifed.

Having thus described my invention, what I claim and desire to protect by Letters Patent is:
