2 Claims. (Cl. 242-131) This invention relates generally to creel structures such as are provided on spinning frames to support the bobbins carrying the roving supply for the spinning operation, and more particularly to an improved creel structure of this sort that provides exceptional flexibility in the supported arrangement of the roving supply bobbins so as to allow arrangement on a spinning frame of a maximum number of bobbins of a given size, or a maximum size of bobbin in a given number.

Briefly described, the creel structure of the present invention comprises an arrangement of bobbin supporting means on stringer members for carrying the roving supply bobbins in depending relation, with the bobbin supporting means adjustable longitudinally of the stringer members, with the stringer members carried on lateral arm members for adjustment laterally thereon, and with these arm members carried for vertical adjustment on an aligned series of spaced post members, so that adjustment in every direction is possible for arranging the supported position of the roving supply bobbins to the best advantage. A further result of this creel structure arrangement is to provide for a more compact disposition of the roving supply bobbins and thereby to lower substantially the necessary creel height, so that it is easier to service and so that convenient top storage space can be arranged thereon. In addition, the several component elements of the creel structure can be readily formed according to the present invention so as to minimize their tendency to collect lint.

These and other features of the present invention are described in further detail below in connection with the accompanying drawings, in which:

Fig. 1 is a perspective view of a spinning frame equipped with a creel structure embodying the present invention;

Fig. 2 is an end elevation, partly broken away and partly in section, of the creel structure shown in Fig. 1;

Fig. 3 is an end view of a stringer member with a bobbin supporting means secured thereon;

Fig. 4 is a sectional detail taken substantially at the line 44 in Fig. 2;

Fig. 5 is a further section detail taken substantially on the line 55 in Fig. 2;

Fig. 6 is a fragmentary detail in end elevation of a modified form of lower stringer supporting means;

Fig. 7 is a side elevation corresponding to Fig. 6; and

Fig. 8 is a diagrammatic illustration of a typical arrangement of roving supply bobbins on a creel structure embodying the present invention.

Referring now in detail to the drawings, Fig. 1 illustrates generally the arrangement of a spinning frame F equipped with a creel structure embodying the present invention to support the necessary number of roving supply bobbins B for withdrawal of roving therefrom to be spun and rewound at the spindles S. The general arrangement of the creel structure provided according to the present invention is illustrated more in detail in Fig.

2,958,479 Patented Nov. 1, 1960 its 2, in which the creel structure is shown to comprise post members 10, which are spaced in an aligned series along the central longitudinal axis of the spinning frame F as shown in Fig. l; lateral arm members 12 and 14, which are carried on each of the post members 10 for vertical adjustment thereon and for disposition in transverse relation with respect to the alignment of the post members 19; stringer members 16, which are carried by the lateral arm members 12 and 14 for lateral adjustment in relation to the post members 10 and for disposition in parallel spaced relation with respect to the post member alignment; and bobbin supporting means 18 (see Fig. 3), which are carried for longitudinal adjustment on the stringer members 16 to support roving supply bobbins B in depending relation thereon.

The post members 10 are each fitted with a base member 20 formed for straddling disposition on the spinning frame F at the roller beams thereof (not shown), and for attachment thereat by means of fastening bolts 20' or the like. The post members 11 are also preferably threaded at their upper ends as indicated at 10' so that they may have the necessary fittings attached thereto for supporting an overhead rail or the like R such as is usually employed for guiding an overhead cleaning device along a spinning frame F.

The lateral arm members 12 and 11 that are carried on the post members 10 have the form of a downwardly opening rectangular channel in cross section (compare Figs. 2 and 4) that is less in width than the diameter of the post members 10 except at a portion thereof, as indicated at 12 and 14 in Figs. 2 and 4, at which the side faces of arm members 12 and 14 are formed outwardly and at which the top face thereof is apertured for fitting slidably over the post members 16, so that means such as

bolts

22 and 24 may be arranged adjacent these outwardly formed portions 12 and 14 for drawing the arm member side faces together in clamping relation on the post members 10 and thereby fix the arm members 12 and 14 in place at a desired vertical adjustment. The arm members 12 and 14 are also specially formed at the downwardly opening face of their channel cross section With

reentrant flanges

26 and 28 which are formed to define a longitudinal slot at which the previously mentioned stringer members 16 may be carried.

The stringer members 16 are tubular in form with a generally triangular cross section and with a slot 30 running lengthwise at the bottom face thereof. These stringer members 16 are carried on the lateral arm members 12 and 14 by pairs of

bracket members

32 and 32 adjustably attached in depending relation at the bottom face of the arm members 12 and 14 by means of bolts 34 inserted at the bottom face slot formed by the

arm member flanges

26 and 28 and engaged by spring nuts 36 arranged within the arm members 12 and 14 to bear at the inside faces of the

flanges

26 and 28 thereof. The bracket members 32 and 3'2 are each formed with

lateral lips

38 and 38 at their depending ends, and they are attached on the arm members 12 and 14 in the above noted manner so that the

brackets

32 and 32 of each pair are spaced to receive the stringer members 16 therebetween to rest on the

lateral lips

38 and 38, with the adjacent edges of the

lateral lips

38 and 38 in turn spaced in substantial correspondence with the width of the lengthwise stringer member slot 30, so as to provide for attaching the stringer members 16 thereto by bolts 40 extended between the bracket member lateral lips: 38 and 38' and through the stringer member slot 30 for engagement within the stringer members 16 by spring nuts 42. The lengthwise slot 31 in the stringer member 16 also serves in a similar manner for carrying the bobbin supporting means 18 thereon, the bobbin supporting means 18 comprising any suitable form of bobbin hanger such as is illustrated in Fig. 3 and having a mounting bolt 44 at the top thereof extended through the stringer member slot 30 for engagement by a spring nut 46.

The upper lateral arm members 12 are also employed for carrying roving rods 48 by means of hanger rods 50 threaded at one end to engage collar elements 52 that may be adjustably fixed on the roving rods 8 with. the hanger rods 5% acting in the nature of set screws. The hanger rods Sharein turn carried at their other ends by sleeve members 54 within which they are slidably adjustable and on which they may be fixed in place by set screws. as indicated at 54. The sleeve members 54 each have a hanger stud 56 formed thereon that may be extended between the bottom face flanges 26 of the lateral arm members 12 to engage a spring nut 53 therein for adjustable attachment to the arm members 12 in the same manner as the

bracket members

32 and 32 for the stringer members 16. By this arrangement, the roving rods 48 are made adjustable both laterally and verti cally for disposition in a desired relation with respect to bobbins B supported on the stringer members 16.

As shown in Figs. 1 and 2, the roving rods 48 are carried on the lateral arm members between the stringer members 15 arranged thereon to carry the two outermost rows of bobbins B at each side of the post members 10. The lateral arm members 12 also carry further stringer members 16 for supporting a third inner row of bobbins B at each side of the post members and the bracket members 38' provided for attaching these further stringer members 16 arranged in a greater length than the bracket members 38 for the other stringer members so that the inner rows of bobbins B are maintained readily accessible behind the outer rows for replacement when necessary. The lower lateral arm members 14 additionally carried on the post members 1% correspond in form to the upper lateral arm members 12 except in extent of reach from the post members 10, the lower arm members 14 having a lesser extent proportioned for carrying a single stringer member 16 at each side of the post members 113 in vertical alignment below the innermost rows of bobbins B on the upper lateral arm members 12 at the normal range of lateral adjustment for these upper inner rows of bobbins B.

The channel shape form of the lateral arm members 12 and 14, as well as the triangular cross section of the stringer member 16 and the cylindrical form of the roving rods 30, results in arranging the principal components of the creel structure of the present invention with a minimum tendency to collect lint, as previously noted above. This advantage is further enhanced by the case with which the ends of lateral arm members 12 and 14, stringer members 16, and roving rods 48 may be closed, respectively, by end caps 12", 14" and 16', or end plugs 48', as shown in Figs. 2, 4 and 5. Figs. 4 and 5 also illustrate the manner in which stringer members 16 and roving rods -48 may be fitted readily with coupling sleeves 16" and 48" so that standard lengths thereof can be employed to form any particular length of oreel structure desired.

Figs. 6 and 7 illustrate a modified form of supporting means for the lower stringer members 16 that may be employed to advantage where the particular form of bobbins B being handled, or space limitations in general, make it desirable to eliminate the vertical alignment of the inner stringer members 16 at each side of the post members 10 on the upper and lower lateral arm members 12 and 14 according to the arrangement illustrated in Fig. 2. The modified stringer supporting means shown in. Figs. 6 and 7 comprises a clamping collar formed by a pair of half collar elements 60 fitted with fastening means as indicated at 62, by which these collar elements 60 may be drawn together in clamping relation on the post members 10, and having each collar element 60 formed in complementary relation with an attaching flange portion 64 at which a bolt 66 may be seated to extend through the length-wise slot 30 in the stringer member 16 and engage a spring nut 68 therein to secure the lower stringer members 16 on the respective collar elements 60. The lower stringer members 16 then have lateral hanger arms adjustably secured by bolts 72 and spring nuts 74 at the stringer member slots 31 for carrying bobbin supporting means 18 at the extending ends thereof, so as to allow disposition of the lower row of, bobbins B in staggered relation with the lower ends of the bobbins B in the upper innermost row depending to some extent therebetween.

Fig. 8 diagrams a portion of a typical arrangement of roving supply bobbins B with the path of roving indicated as withdrawn therefrom for doubling at each of the spindle positions. which are designated by the transversely broken lines in Fig. 8. This diagram illustrates very well the compactness in the supported arrangement of the roving supply bobbins made possible by the creel structure of the present invention on' which the longitudinal spacing of the bobbins: B in each row is independently ad.- justable, on which the lateral spacing of each row of bobbins B is independently adjustable, and on which the vertical positioning of the upper and lower tiers of bobbins B is independently adjustable.

The present invention has been described in detail above for purposes of illustration only and is not intended to be limited by this description or otherwise except as defined in the appended claims.
