Claims. (01. 242-131) The invention relates to creels for holding supply packages of yarn to be fed to warpers or other textile machines, and relates more particularly to an improved bracket for supporting yarn packages on the creel.

In winding section beams on a warper, packages of various designs, such as bobbins, cones or tubes are usually mounted on brackets which are in turn mounted on the vertical bars of a creel. Prior to the instant invention, the brackets were arranged to revolve around the center of a vertical or around the pin opposite from the vertical bar to facilitate the replacement of yarn packages thereon. Accordingly, the center-tocenter spacing of the vertical bars of the creel was regulated by the length of the package. Where magazine packages were employed, the spacing of the bars was necessarily wide since a magazine package is a long unit. It is, accordingly, an object of the present invention to provide an improved bracket adapted to be mounted on' a vertical bar of a creel, which reduces the width of the spacing required between the vertical bars.

Another object of this invention is the provision of an improved bracket, adapted to be mounted on a vertical bar of a creel, for supporting two yarn packages.

Still another object of this invention is to provide an improved bracket, adapted to be fixed in position on a vertical bar of a creel, having means thereon for supporting two yarn packages, which supporting means are movable relative to said bracket.

Other objects of this invention, together with certain details of construction and combinations of parts, will appear from the following detailed description.

In the drawings wherein a preferred embodiment of our invention is shown,

Fig. 1 is a detail view, in perspective, showing a number of brackets of our invention mounted on the vertical bars of a standard type of creel, such as a Cooker transfer type creel,

Fig. 2 is a detail view, on an enlarged scale, of

our novel brackets mounted on a vertical bar of a creel, the yarn packages being of a different type than those shown in Fig 1, and

Fig. 3 is a plan view showing the relationship of two horizontal adjacent brackets and also showing how the transfer of yarn is effected.

Like reference numerals indicate like parts throughout the several views of the drawings.

Referring now to Fig. l of the drawings, the reference numeral 4 indicates two vertical bars of a creel which are mounted in collar brackets 5 fixed as by bolts 6 to a cross-piece l which may rest on or be bolted to the floor. Fixed to said vertical bars 4' are brackets generally indicated by reference numeral 8 on each of which two yarn packages may be supported, the yarn from said packages being taken off said yarn packages on to a section beam on a warper, or on to any other desired yarn support.

The brackets 8 comprise a platform 9 fixed to a collar II which inturn is fixed in a predetermined position on the vertical bar 4 of a creel. The platform is preferablypolygonal in shape and is provided adjacent two sides thereof with longitudinal slots l2 which are divergent. The near ends of said divergent slots are enlarged to pro vide substantial circular openings l3 extending into which are stops or shoulders l4 and l5. On either side of the other ends of the slots l2 the platform 9 is provided with depressions I 6, the purpose of which will hereinafter be described.

A yarn package holder is slidably mounted in each slot I 2 of the bracket. These yarn holders comprise a base formed of two coextensive plates I! and 18, one on top and one below platform 9, held together somewhat loosely on the platform by means of bolts I9 extending through slot l2. To top plate I! of the base is fixed a substantially vertical bracket member 2|, the top of which is bent over to form a hand hold 22 by which the yarn package holder may be moved'in slot l2. A spindle 23 is fixed to each bracket member 2 l, extending substantially at a right angle thereto. The spindles are adapted to receive any suitable yarn package such as is indicated by reference numeral 24 in Fig. 1 and by reference numeral 25 in Figs. 2 and 3. Base plate I! is provided with balls 26 and baseplate It! with balls 21.

Referring now to Fig. 3 for a description of the operation of our novel bracket for supporting yarn packages on a creel, the brackets containing the full bobbins are pushed into position at the divergent ends of slot' l2, the yarn 28 from one bobbin A of each pair of bobbins is taken off therefrom and led through a yarn guide 29 to the warper or other textile machine. The yarn 3| from the other bobbin B is tied onto the transfer tail of the adjacent bobbin A in the adjoining bracket. Thus, at this point bobbin B may be considered the supply bobbin.

When the yarn on bobbin B is all taken off, the bracket is pulled backwards in slot l2 until the bolts l9 enter opening l3, the bracket is then turned' until bolts I 9 come into contact with shoulders l4 and I5, one bolt coming into contact 3 with shoulder l4 and the other into contact with shoulder I5. The spindle and bobbin at this point will be at a right angle to slot l2 making for ease in doinng the depleted bobbin and donning a full bobbin. The bracket is then given a reverse turn and pushed into position at the other end of slot H, where balls 26 enter depressions I6 to hold the bobbin in position.

Balls 21 on plate 3 act as bearings when the operative presses downwardly on bracket member 2i to release balls 25 from depressions l9.

It is to be understood that the foregoing detailed description is given merely by way of illus-' tration and that many variations may be made therein without departing from the spirit of our invention.

Having described our invention, what we de sire to secure by Letters Patent is:

1. A yarn package support for a creel comprising a platform supportable on a bar of said creel, said platform having a slot including a substantially circular opening at one end thereof, and a yam package holder mounted on said platform for substantially straight-line movement in said slot and for angular movement in said opening in said slot.

2. A yarn package support for a creel comprising a platform supportable on a bar of said creel, said platform having a slot including a substantially circular opening at one end thereof, a yarn package holder mounted on said platform for substantially straight-line movement in said slot and for angular movement in said opening in said slot, and means in said opening for limiting the angular movement of said yarn package holder.

3. A yarn package support for a creel comprising a platform supportable on a bar of said creel, said platform having therein two divergent slots each having a substantially circular opening at one end thereof, and a yarn, package holder mounted in each of said slots for straight-line movement in said slots and for angular movement in said openings in said slots.

4. A yarn package support for a creel comprising a platform supportable on a bar of said creel, said platform having a slot therein, a yarn package holder mounted in said slot for movement relative to said platform, said yarn package holder including a plate on top of said platform, a second plate below said platform, means extending through said slot for connecting said plates, a vertical bracket member on one of said plates and a spindle on said bracket member, and means on the upper plate cooperating with depressions in the upper surface of said platform for holding said yarn package holder in operative position.

5. A yarn package support for a creel comprising a platform supportable on a bar of said creel, said platform having therein two divergent slots each having a substantially circular opening at the near ends thereof, a yarn package holder mounted in each of said slots for straightline movement in said slots and for angular movement in said openings in said slots, said yarn package holder including a plate on the top of said platform, a second plate below said platform, bolts connecting said plates, a vertical bracket member on one of said plates and a spindle on said bracket member, means in said openings cooperating with said bolts to limit the angular movement of said yarn package holder, and means for holding said yarn package holder in operative position.
