Application filed February 15, 1926. Serial No. 88,261.

vention and of a type adapted to be clamped upon an arbor.

My invention relates to a core for spools, reels, bobbins and similar articles which are designed to act as holders for such commodities as wire, thread. yarn, Cordage, filaments, ribbons. note-sheets, or webs of flexihis material. The articles so named may be fundamentally the same with respect to construction and function, the difference being rather a matter of size and the relative proportions of their component parts. For convenience of description, I shall use the word spool in a broad generic sense to describe the devices listed above and all other devices of kindred nature and use.

In marketing certain commodities, such, for example, as insulated electric wire, it has become a well established trade custom to employ a type of spool wherein the coaxial arbor-receiving core-hole is of comparatively small bore as compared with the outside diameter of the body or barrel-element. This trade requirement of a spool having a small bore and a barrel of large outside diameter has heretofore been met by spool-structures having either thick solid walls of objectionable weight, or complicated skeletoniz-ed forms of relatively high cost.

The object of my invention is to provide, at a low cost for manufacture, a simple selfcentering core-element of the class described which shall combine rigidity and strength with lightness of weight.

WVith this general object in view, my invention consists in a core-element characterized by having asubstantially-tubular arbor-receiving member provided with longitudinally-disposed spool-supporting vanes.

My invention further consists in a coreelement having certain details of Construction as will be hereinafter described and particularly recited in the claims.

In Figs. 1 and 2 of the drawings, I have shown my invention embodied in a coreelement of a type which lends itself most readily to manufacture by moulding or extrusion processes. As shown, the arborreceiving tube 10 is provided with three-integral "longitudinally-disposed radial spoolsupporting vanes 11 which are adapted to engage with the interior of a barrel-member 12 of a spool-structure, which may be of any approved construction and which includes. as shown, end-flanges 13.

In 3 of the drawings, I have shown a core formed from a single strip of sheetmetal which is bent to form three tangen tial spool-supporting vanes 14 and an arborreceiving tube 15, from which latter the vanes 14 offset.

In order to secure the core element in the spool proper, I prefer to so proportion the radius of the vanes that when the unit is installed within the barrel of a spool, its fit will be sufficiently tight to retain it in place by friction, or the vanes may be caused to slightly embed themselves in thebarrel, when the material from which the latter is formed will permit of this.

While it may be true that my initiallyseparate core-element will find its greatest field of usefulness when incorporated in a spool-structure as a permanent part thereof, I also recognize the fact that there are certain conditions which make it desirable to attach the core-element to existing spoolarbors and thereby adapt the arbors to receive spools having bores of a diameter exceeding that of a standard arbor. lVith this particular requirement in mind, I provide a core such as is shown in Fig. 4. As shown this core is formed from a single strip of sheet-metal, which is bent to form three radial spool-supporting vanes 16 and an arborreceiving tube 17, from which the vanes 16 offset. The ends 18 of the strip of metal thus bent are perforated to receive bolts 19 by which the tube 17 may be clamped upon an arbor such as that shown by broken lines in Fig. land designated by the numeral 20. After a core of this type has been clamped upon an arbor, spool-structures may be forced over the vanes and removed therefrom as required.

As is obvious from the foregoing description, the material from which my improved core is formed is of but slight importance. since there are great varieties of materials suitable for this purpose. I would have it understood that while I have shown my improved core as provided with three vanes running lengthwise thereof, it is obvious that the vanes may he more or lees in number and heiicaii) curved if desired.

I claim:

1. As a new artirie of manufacture, a skeleton core for spools, reels, and the like. comprising a substantially-tubular arbor receiving hotly provided with integral (iiverging longg'itutti11a1iyiisposed spool-sup porting ran-es separated one from the other thronghout their length by open spaces.

2. A core for spools. reels and the iike, fOi'l'llGd from sheet-metal bent to term a substantially-tnbular arbor-receiving member and diverging longitudinailydisposed spoolsupporting vanes.

memes 3. A core for spools, reels and the like, formed from a single strip of sheet material hent to Form a substanthilly-tubular arborrereiving member and diverging longitudinally-disposed spool-snpporti11g vanes.

i. A core for spools, reels and the like, termed from eheet-n'ietal bent to form a substantialiy-tubuiar arbor-receiving member and diverging longitudinally-disposed spool.- supporting vanes, one of the said vanes being formed in two parts and means For clamp ing the two parts together, whereby the core may he chnnpeti upon an arbor.

In testimony whereof, I have signed thie specification.
