Application November 22, 1950, Serial No. 197,134

10 Claims. (Cl. 242-130) This invention relates to bobbin holders or the like for use in textile machines.

An object of the present invention is to provide a bobbin holder arrangement including a set of interchangeable adaptors, which arrangement may be used for a great variety of bobbins of dilferent shape and type, for example, rayon cones, cotton cones, pineapple packages, nylon pirns, etc.

A further. object of the invention is to provide a bobbin holder which may be readily used in conjunction with different kinds of adaptors for various types of bobbins or yarn packages.

Another object of the present invention is -to provide a bobbin holder of such construction that its radius of swinging about the axis of a holding rod is reduced to a minimum, so that if bobbin holders according to the invention are used in conjunction with a creel, the distance between the holding rods of the creel and, consequently, the overall length of the creel, can be held to a minimum.

A further object of the invention is to provide a bobbin holder which permits an easy and effective attachment of a holder carrying a pad "of sheepskin or the like.

Another object of the invention is to provide an adaptor for use in conjunction with a bobbin holder, which adaptor is capable of receiving cones of different taper.

Still a further object of the present invention is to improve on the construction of bobbin holders and bobbin holder arrangements as now customarily made.

Other objects and structural details of the invention will be apparent from the following description when read in conjunction with the accompanying drawings forming part of this specication, wherein:

Referring now to Figs. 1-5, 20 indicates a holding rod pertaining to a textile machine, for example, a creel.

A set collar 22 slid over the holding rod 20, and arranged between the forked ends 24 of an arm 26 of the bobbin holder is held in its position by means of a set screw 28. Each of the forked ends 24 has a bore 30 rotatably engaged with the holding rod 20. The free end of a spring 32 (see Figs. 3 and 5) secured to the arm 26 by a screw 33 may come into operative engagement with a recess 34 of the set collar 22 for holding the swingable arm 26 in a predetermined position.

As best shown in Figs. l and 5, the other end 36 of the arm 26 is oiset relative to the center C of the bores of the forked ends of the arm. This ofset end 36 carries a boss 38 of conical shape, and is provided with a bore 40.

One end of a shank 42 is inserted into the bore 40 of the boss 38, and is iixedly secured thereto.

As best shown in Fig. 2, the shank 42 is provided at opposite sides with longitudinal slots 44 communicating with each other by a bore 46. The crown of a wire spring generally indicated by 48 is inserted into this bore 46, the legs of this wire spring extending longitudinally from the shank 42 on opposite sides thereof. Each leg of the spring 48 has two bowed portions 50 and 52 adjacent each other. The bow 52 is somewhat larger than the bow 50. The portion of the spring 48 between these two bows 50 and 52, as well as the free end of each leg of the spring, is slidably engaged with the slot 44 of the shank 42. Upon compression of one or both bowed portions of each leg of the spring 48, the free end of the leg slides along the associated slot 44 to the left, as viewed in Fig. 2.

Furthermore, the free end portion of the shank 42 is provided with a trst circular groove 54, and a second circular groove 56, the latter being narrower than the former.

As shown in Figs. l, 3 and 5, the end 36 of the arm 26 is provided with a lug S8 for purposes to be described further below in detail.

The above described bobbin holder, comprising the arm 26 and the shank 42 provided with the double-bowed wire spring 48 may be used for carrying a bobbin or the like directly or through the medium of an adaptor placed on the shank 42.

According to the arrangement shown in Fig. 1, a spacing element 60 having a center bore 62 and diametrically opposite longitudinal grooves 64 (see also Fig. 4) is placed on the shank 42 in such a manner that the bowed portions 50 of the wire spring 48 come into engagement with these longitudinal grooves 64, whereby the spacing element 60 is held in a certain position. The bowed portions 50 engaged with the longitudinal grooves 64 prevent the spacing element 60 from rotation. The spacing ele ment 60 may be made of wood or any other suitable material.

Upon attachment of the spacing element 60, an adaptor, generally indicated by 66, and provided with a center bore 68 is placed on the shank 42. Due to the small diameter of the center bore 68, the bowed portions 52 of the wire spring 48 are compressed, the latter tending to hold the adaptor 66 in place.

Preferably, a snap ring 70 is engaged with the circular groove 56 of the shank 42 so as to prevent the adaptor 66 from axial displacement. The adaptor may be made of wood, or other suitable material, for example, a plastic.

The adaptor 66 comprises two portions 72 and 74 of conical shape, the taper of the portion 72 however, being of a lesser degree than the taper of the portion 74. Furthermore, the conical portion 72 is provided with an annular groove 76.

According to the arrangement shown in Fig. l, the core 78 of a rayon cone 80 is engaged with the conical portion 72 of the adaptor 66.

If a bobbin holder is used in a creel, it is necessary to swing the arm 26 carrying the shank 42 around the holding rod 20 for loading of the bobbin holder with a bobbin or the like, or for the removal of an empty core.

As will be readily understood from an inspection of Fig. 5, the swinging radius r caused by the distance between the center C and the end of the shank 42 is smaller than it would be were the end 36 of the arm 26 not offset relative to the center C. Consequently, it is possible to reduce the distance between two adjacent hold ing rods in a creel, with the result that the overall length of a creel may be considerably lessened.

Fig. 6 illustrates a different use of the bobbin holder arrangement shown in Fig. l. The same spacing element 60 and the same adaptor 66 are applied to the shank 42 carried by the arm 26 mounted on the holding rod 20. ,However, a ring-shaped coil spring, or garter spring 82 is inserted into the groove 76 of the adaptor 66,

so that the latter may safely carry the core 84 of a cotton cone 86. The conical core 84 of the cone 86 having a higher degree of taper than the conical core 78 of the cone 80 shown in Fig. 1 is engaged with the portion 74 of the adaptor 66 and the garter spring 82, as shown in Fig. 6.

Furthermore, according to Fig. 6, a holder 88 carrying a pad 90 of sheepskin or the like for cooperation with the cone 86 is attached to the spacing element 60 by Irdri'ears of screws, only one screw 92 being shown in According to Fig. 7, instead of the spacing element 60 and the adaptor 66 described above, an adaptor 94 of the compressible cage type, substantially of the construction described in my Patent No. 2,437,100, is mounted on the shank 42 of the bobbin holder, according to the invention. The adaptor 94 is held in its position by means of a set screw 96 engaged with the circular groove 54 of the shank 42. The base 98 of the compressible cage type adaptor 94 is in engagement with the bowed portions 52 of the wire spring 48 of the shank 42. The compressible cage type adaptor 94 may be used for carrying a rayon or cotton cone.

According to the embodiment shown in Fig. 8, the spacing element 60 carrying a holder 88 provided with a pad 90 of sheepskin is mounted on the shank 42 of the bobbin holder, in addition to the cage type adaptor 94.

According to Fig. 9, the bobbin holder is made ready for carrying a so-called pineapple package 100. Again the spacing element 60 and the conical adaptor 66 described above in connnection with Fig. l are mounted on the shank 42 carried by the arm 26 of the bobbin holder. The core 102 of the pineapple package is engaged with the conical portion 72 of the adaptor 66. A holder 104 carrying a pad 106 of sheepskin is attached to the spacing element 6i). The holder 104 and pad 106 are shaped so as to suit the form of the pineapple cone 100.

According to Fig l0, the bobbin holder comprising the arm 26 and the shank 42 attached thereto is used for carrying a nylon pirn 108. This pirn 108 has a cylindrical core 110, so that it becomes unnecessary to apply an adaptor to the shank 42. The end wall 112 of the core 110 is provided with an opening 114 engaged with the conical boss 38 of the arm 26.

Furthermore, the center wall of the core 110 is engaged with the bowed portions 52 of the wire spring 48. Thus, by the engagement of the opening 114 with the boss 38, and the inner wall of the core 110 with the bowed portions 52 of the spring 48, the pirn 108 is safely held in position. Too, the bent resilient end of a holder 116 carrying a pad 118 of sheepskin is clipped on the lug 58 arranged at the end 36 of the arm 26.

It will be noted that the left hand end (as viewed in Fig. l) of the pirn 108 extends into the space formed between the boss 38, and the bent portion of the arm 26.

As will be understood from above, the bobbin holder according to the invention may be readily used for a great variety of different types and shapes of bobbins or the like. The adaptors may be readily interchanged so as to accommodate a bobbin or the like of any desired type.
