WOUND PACKAGE.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed June 7, 1918. Serial No. 238,744.

To all whom it may concern:

Be it known that I, EMERSON C. WEST, a citizen of the United States, residing at W'eatherly, in the county of Carbon and State of Pennsylvania, have invented certain new and useful Improvements in \Vound Packages, of which the following is a specification.

My invention is an improvement involving the employment in the art of secondtime twisting or spinning of a resistance medium, consisting of plush or other suitable pile-like material, around the upper end of the supply package of windings, thus to dispense with the use of a flier, the invention consisting in so constructing the upper head of the spool forming the core of the windings and s0 associating the resistance medium with such head that, among other advantages, the wide disparities in tension at present due to the yarn paying off more freely when delivering from the upper part of the package (as an incident to its balooning) than when paying off from the lower part of the package (on account of its then wrapping around the package in a coil extending longitudinally of the package), will be reduced to the minimum. To this end, in

the preferred form of the invention I have provided a head on the spool of the package which is of greater diameter than the windings, so that with the resistance medium arranged peripherally of said head such resistance medium in effect reaches out to the yarn so as to damp or resist its whirling (i. e. oppose tension) at times when (with the yarn paying off from the upper portion of the package) tension would otherwise be absent or unduly low; and so as to eliminate as far as possible tension factors of a different character from that of the particular (pile-like) resistance medium employed, as that opposed by the material of the spool head proper, and particularly so that as little resistance of this kind as possible be added to that due to the wrapping (or tendency thereto) of the yarn around the package when the delivery is from its lower portion, I dispose the resistance medium in a groove in the spool head and bevel the head both above and below the groove to a limited yarn-contact edge or lip immediately adjacent to the groove. I further depress the groove in the head below the central horizontal plane of the head, which has the two-fold result of disposing the resistance medium to best advantage as a tension factor and adapting the head to resist breakage or nicking.

In the accompanying drawing,

Figure 1 is a side elevation of my improved wound package, showing the yarn delivering in the second time spinning or twisting operation upward through a suitable guide;

Fig. 2 is an enlarged sectional fragment of the upper part of the package; and

Fig. 3 is a plan view showing a part of the head 03 broken away to illustrate the manner of securing the resistance medium in lace.

p a in the drawing designates the spool and b the windings thereon. The spool has heads or flanges 0 and d, the upper one of which is of appreciably greater diameter than the outermost layer of the windings b.

Embracingthe head or flange (Z peripherally thereof is a band of pulsh, felt, cotton, chenille, silk or other material 6, being preferably fibrous material and preferably arranged in as low a horizontal plane therein as possible.

By making the upper head or flange cl of greater diameter than the outermost layer of windings b, the resistance medium 6 is made to reach out laterally so as to insure the yarn, as it is drawn upwardly through the eye f and balloons in consequence of the simultaneous rotation of the package with the spindle g which carries it, engaging the resistance medium not only when the delivery is taking place (as shown by the full line A in the drawing) from the lower end of the package but when it is taking place (as shown by the dotted line B in the drawing) from the upper end thereof and when consequently the ballooning is greatest. The effect desired is advantageously enhanced and at the same time the head, when grooved to receive the resistance material as hereinafter explained, is made to be better adapted to resist breakage or nicking if the resistance medium, as shown best in Fig. 2, be placed as low as possible in the head: this leaves increased thickness of material above the resistance medium to withstand shocks or blows and disposes the resistance medium more perfectly in the range of the ballooning yarn.

It is very essential in orderto. obtain the best results as to tension by the use of a resistance medium placed around the periphery of the upper part of the spool, to subject the yarn to as little other influence opposing resistance thereto as possible; thisisespecially true where plush, chenille, or other pile-like material. is employed and where the resistance is opposed by the upstanding fibers of the material and in consequence is extremely delicate in character. Therefore, in the preferred construction I form a pcripheral groove it in the head d and place the resistance medium 6 therein, and I further bevel the periphery of the head orfiange to a limited-contact, preferably rounded edge 71, both above and below the groove. In consequence, the yarn at no time has contact with the periphery of the head (Z above the material 6 except at the upper lip or edge 2', and most of the time has contact with said periphery below the material 6 substantially only at the lower edge or 1i 2', wherefore friction between the yarn and thehead enters in as'little as possible as a factor modifying the influence of the resistance medium e.

IIaving thus fully described my invention, what I claim and desire to secure by Letters Patent is: I

In combination, means to support the windings of a wound package of the class described'and a head arranged above the windings, said head having a peripheral groove arranged below its central horizontal plane and pile-like yarn resistance material in the groove, and said head being of greater diameter than the windings adapted to be placed onsaid means, the periphery of the head above and belowthe groove being beveled to a limited yarn-contact edge or lip immediately adjacent to the groove.

In testimony whereof I aflix my signature.
