FLYER FOR UNWINDING CAKES AND OTHER PACKAGES Filed Oct. 30, 1946 Patented July 8, 1952 7 lac-02,606

FORUNWINDING'GAKES AND 1 OTHER rAoKAG s 7 6. llanseplhiladelphia, Pa assignor to Am ican ,Viscose Corporation, Wilmington, De ta or or t n of la are Application October 30, 1946, s r ai'ivog 'zoenoe This invention relates to improved fiyers for unwinding cakes, cops, bobbins and other packages on which yarn, thread, strands and other filamentary materials are wound.

In-devices of the prior art, the necessity often arose wherein it was expedient to replace the traveler on the fiyer assembly, because of undue wear or the like; This usually meant that either most ofthe fly'er had to be disassembled or the fiyer had to be scrapped. This disadvantage of the prior art is overcome in the present invention.

The primary object of this invention is to provide 'an improved fiyer and traveler with means for readily removing the traveler from the flyer.

Other objects and: advantagesyof the present invention will become apparentfrom a study of the description ofthe drawings herein.

In the drawings:

7 Figure J. is a top view of an illustrative em- :bodimentof the invention, v 1 Figure 2 is a side view,

" Figure-3 is an end view of the vertical armof the flyer of Figure 1, Figure 4 is a modification using a circular shank traveler, and I Figure 5 is a modification using a straight shank traveler. 1

' As shown in Figures 1 and. acter 2 indicates a holder on which a wound cake is supported. This ma be a cake 3 produced in a spinning pot, such as is used in the rayon industry. The spindle 4 which protrudes through the center of the cake has a collar 5 mounted near its free end. The spindle 4 may be made so that' the cake fits loosely or tightly, however it is preferable that it fit tightly in order that it restrict rotation of the cake thereabout. The collar 5 supports a hub 6 rotatably mounted thereon. The hub 6 may be equipped with a plain, self-lubricating or anti-friction bearing, the main consideration being that the device be as free-running as possible.

The hub 6 supports the frame I mounted generally perpendicular to its axis of rotation. The frame 1 consists of two laterally displaced rods such as wire or the like. Although the frame l is mounted generally perpendicular in this case, it can be mounted at any angle and still produce good results. Adjustably mounted on the free end of the frame 1 is a counterweight 8, that. smooths the rotation of the fiyer assembly 9. The frame I is constructed in such a way that part cake or other wound package 3. 'I'hi.s part of the 2, reference charthe axis of rotation of the fiyer. mounted at the bend in the frame I is a porcelain eye [0, through which passes the yarn l I from the frame maybe constructed so that His other than parallel to the cake, but it has been found that the best results are obtained when it is parallel. The wires, as shown in Figures 1 and 2, are .in a common plane which extends transve'rsely to a plane containing one of the wires and Suitably cake'3, via the traveler l2 whose vertical travel is limited by stops [3 and. I

The frame 1 is constructed so that the traveler |2 can be replaced by squeezing the two rods,

wiresor the like together, whichaction allows thetraveler to be removed. These rods or wires are resilient so that they will regain theiroriginal the internal diameters or dimensions of the traveler are different, the longer dimension adapting the traveler to slidably embrace the rods I without distortion thereof, and the space within the interior of the traveler as viewed in Figures 4 and 5. (i. e. in a direction at right angles to the plane of the traveler) .is ovate or elongate. The gap lid is disposed in one of the longer sides of the traveler so that, in operation, the traveler cannot rotate relative to the parallel rods 1 of the frame. In operation, the traveler is mounted on rods 1 with the closed side of the traveler towards the package 3 and the gap away from the package. It is important that any type traveler used must have a gap [2a in it so thatit can be removed from the frame.

As shown in Figure 2, the flyer assembly 9 may be modified so that it can be used on a cake holder that is in any position from the horizontal to the vertical. The free end of the spindle 4 is threaded to accommodate the lock nut I6, which bears upon a washer or the like [5 holding the spring I! against the washer or the like l8 which creates a bearing surface for the flyer hub 6. With an assembly of this sort, it is easy to remove this spring device because it does not have to be in place when the cake holder 2 is in the horizontal position.

In operation, the thread, strand, yarn or other filamentary material is taken from the cake 3 and passes through the traveler l2 and from there through the porcelain eye I0. As the yarn is drawn ofi the cake, the fiyer rotates and the traveler reciprocates between the two stops l3 and M. The frame .1, is of such a resiliency that it will 1.
