15 Claims.

This invention relates to racks for supporting yarn packages such as bobbins or spools, with or without cones or other core members, and particularly to the type of rack which normally consists of a support provided with perpendicularly disposed pins or posts arranged in relatively spaced predetermined order afiording clearance between the yarn packages respectively mounted on the posts.

Some of the objects of the present invention are, to provide a rack of rugged durable construction and light of weight having the posts permanently secured thereto; and to provide such a rack which is particularly adapted for use in connection with braiding machinery to facilitate the handling of yarn packages.

With these and other objects in view, which will become apparent from the following detailed description of the illustrative embodiments of the invention shown in the accompanying drawings, my invention resides in the rack having the novel elements, features of construction and arrangement of parts, as hereinafter more particularly pointed out in the claims.

In the accompanying drawings:

Fig. 1 is a perspective view of a rack constructed in accordance with the principles of the present invention;

Fig. 2 is a transverse sectional elevation taken on the line 22, Fig. 1;

Fig. 3 is a plan view;

Fig. 4 is a fragmentary sectional elevation taken substantially on the line 4-4, Fig. 3;

Fig. 5 is a fragmentary plan View of my novel rack and shows a modified form of spool supporting post and the manner in which the spool is held thereby; and

Fig. 6 is a transverse sectional elevation taken on the line 6-6, Fig. 5.

The rack primarily comprises a skeleton frame 1 having a plurality of relatively spaced posts 2, 2, cast or otherwise formed homogeneously integral and in one piece with the frame, the whole of the structure including the frame and the posts being composed throughout of light weight relatively tough material, such for example as aluminum, its derivatives or equivalents.

The skeleton frame, in its preferred form, is of rectangular contour and comprises longitudinally extending side bars or members 3 and 4 respectively and a central longitudinally extending bar member 5, integrally connected by transversely extending end bar members 6 and 7 respectively and by a plurality of intermediate transversely 55 extending

bar members

8, 8 and 9, 9 respectively.

The

transverse bar members

9, 9 are disposed adjacent and parallel to the end bar members 6 and '7 respectively and are connected thereto by short longitudinally extending

bar members

10, 10.

The posts 2, 2, in the preferred form of the invention, are arranged in longitudinal and transverse rows with a post disposed at the intersections of each of the

transverse members

8, 8 and 9, 9, with the center line of the central longitudinal member 5 and with parallel lines drawn through the centers of the intermediate

longitudinal bar members

10, 10.

Each post 2, in the preferred form of the invention, is of cruciform cross section and comprises four substantially

perpendicular ribs

11, 11 disposed at ninety degrees apart, circumferentially of the post, alternating with substantially

semicircular grooves

12, 12.

The outer edges or surfaces of the

ribs

11, 11 taper inwardly from the base of the post to the top thereof where the oppositely disposed

ribs

11, 11 are joined by and blend into a substantially semi-spherical top surface 13 into which the bases of the grooves 12 also blend.

Each post 2 is provided with a base 15, in the present instance of circular form, from the top surface of which the

ribs

11, 11 and

grooves

12, 12 of the posts 2, 2 extend.

The outer surfaces of the ribs 11 form bearing surfaces for engagement with the wall of the bore or central opening of the core member 14 of the bobbin or spool mounted on the post, with one end of the core member resting on the flat base 15 of the post.

In the present case the top surfaces of the post bases 15 are all disposed in a single plane which preferably is coincident with the planes of the top surfaces of the longitudinal and transverse bar members 3, 4, 5, 6, '7, 8 and 9, providing a smooth top on the frame.

The end and side bar members 3, 4, 6 and '7 are relatively deeper than the intermediate longitudinal and

transverse members

5, 8, 9 and 10 but in each instance these members are of a substantially elliptical cross-section having substantially semi-circular top and bottom surfaces 16 and 1'7 respectively connected by straight or slightly curved side surfaces 18 and 19; and the outer edges of the circular post plate-like bases 5 15, which extend laterally beyond the side edges of the bars from which the posts project, are rounded as are the corners of the skeleton frame and the corners where the various intersecting members join with each other, all with a view of 110 eliminating any and all sharp edges and corners which could catch and injure the yarn or threads wound on the bobbins or spools supported on the rack.

Fig. 5 of the drawings illustrates a modification of the post construction wherein the post 211 is provided with one or more oppositely disposed pairs of grooves 12a, 12a for receiving

bowed legs

20, 20 of an inverted U-shaped spring 21, the leg connecting portion 22 of which rests on the top curved surface 13a of the post 2a and is secured thereto by a screw 23. This construction is adaptable for firmly supporting bobbins or spools on the rack wherein the bore of the bobbin or spool by wear or by being in some manner slightly larger than the standard size, which snugly and firmly fits the posts 2, would not fit the posts 2 closely enough to prevent looseness therebetween.

The rack in either case with the homogeneously integral posts thereon may be cast in one piece, in the old well known manner in sand flasks but preferably is produced by die casting, whereby all the edges and surfaces will be smooth Without necessitating grinding or buffing to remove fins or roughness as produced by the sand mold process.

Of course, the rack device specifically shown and described can be changed and modified in various ways without departing from the invention herein disclosed and hereinafter claimed.
