6 Claims.

This invention relates to a cord holder.

It is the primary object of this invention to provide a cord holder in the form of a hollow spherically shaped casing or holder formed of two separable shell sections held together by a friction t between two telescoping core tubes disposed within the shell sections of which each has fixed thereto one of the core tubes, the cord being wound on the outercore tube and the shell section carrying the outer core tube having diametricallyv 4opposed securing means for the ends of the cord. v

With the foregoing and other objects in view, the invention resides in the novel arrangement and combination of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment' 'of the invention herein disclosed may be made Within the scope of what is claimed Without departing from the spirit of the invention. t

A practical embodiment of the invention is illustrated in the accompanying drawing, Where- Figure l is an elevational View of the cord holder. Y

Figure 2 is a transverse sectional view of the cord holder showing the shells forming the same separated, the core tubes, and a cord wound on one of the 'core tubes.

Figure 3 is a detail sectional view on line 3 3, Figure 2, showing lip and spring clip construction on flange of the female shell.

Figure 4 is a plan view of the lip and spring brought together the flanges I4 and I5 will abut each other as clearly shown in Figure l.

At diametrically spaced points on the ange I5 of the shell I2 there is formed by a depression of the ange, lips IB and I'I, see Figure 2. A spring clip I8 is seated on the flange I5 and eX- tends across each lip, one end of the spring clip I8 being pivotally secured to the flange I5 by a rivet I9, while the free end is provided with an upstruck recess 20 adapted to seat over a correspondingly shaped upstruck protuberance 2I formed in the flange I5. The spring clip I8 is biased so as to frictionally contactthe flange I5 and particularly to provide agfrictional engagement of the protuberance 2I and its seatV 20. Preferably the free terminalend of the spring clip I8 is upturned as at 22 to provide an abutment to facilitate movement of the spring clip I8 from its operative position to its inoperative (dotted line) positiomsee Figure 4.

The flange I4 of the shell II is provided at diametrically opposed points with c ut-away portions 25y and 26 adapted to accommodate respectively the spring clips I8 of the lip I6 and I'l when the shells II and I2 are brought together, as clearly shown in Figure 1.

Within each shell there is provided a core tube, arranged to telescopically `engage each other on an axis normal to the mating plane of the shell iianges I4 and I5. Thus, the core tube 28 of the male shell II is provided at one end with a flange 29 contacting the inside surface of the .shell and secured thereto as -by welding, brazing, soldering or any other desired form of securing means. In a like manner the core tube 39 of the female shell I2 is provided at one end with an attaching flange 3I ,similarly secured to the shell I2. At its other end the core tube 30 is provided with a holding flange 32 for a purpose to be hereinafter described. The core tube 3 9 is of a greater diameter than the core tube 28 which is such as to permit telescoping movement of the core tube 28 Within the'core tube 30. Both core tubes are of a length such as to extend a substantial distance beyond and outwardly of the plane of flanges of said shells whereby to retain their telescopic engagement when the shells are separated. Preferably it is intended that the core vtubes 28 and 30 slidablr engage each other in a tight friction fit sufficient to maintain the shells II and I2 in their operative relation, regardless whether they are open or closed.

To wind the cord, the shells II and I2 are separated in the manner as shown in Figure 2. One end A of the cord 33 is placed in the lip I6, the spring clip I 8 being first moved outwardly to permit the placement of the cord end A in the lip and then moved over the lip so 'as toA clamp the cord in the lip. The cord 33 is "then y wound on the core tube 3ilbetween the attaching flange 3| and holding iiange V32, the other end B of the cord being placed inthe lip Il and locked therein by the spring clip I8.v The shells II and I2 are then moved together to conceal the wound cord, the shells remaining together by action of the friction t between the two core tubes.

Having thus set forth and disclosed the nature of this invention, what is claimed is:

1. A cord holder comprising a pair of complemental opposed substantially semi-spherical shells, a peripheral radial flange formed on each shell abutting each other, a core tube within one shell adapted to have a cord wound thereon, a core tube on the other shell telescoping Within said rst mentioned core tube and having a sliding friction fit therein whereby to maintain said shells in assembled relation.

2. A cord holder comprising a pair of complemental opposed substantially semi-spherical shells, a peripheral radial flange formed on each shell abutting each other, a core tube within one shell adapted to have a cord wound thereon, a core tube on the other shell telescoping within said first mentioned core tube and having a sliding friction iit therein whereby to maintain said shells in assembled relation, and a pair of diametrically opposed cord securing means provided on the flange of one of said shells.

3. A cord holder comprising a pair of cornplemental opposed substantially semi-spherical shells, a peripheral radial flange formed on each shell abutting each other, a core tube Within one shell rigidly secured thereto, an outer core tube within the other shell and rigidly secured thereto, said core tubes being each of a greater axial length than the depth of'sad shells and in coaxial alignment and telescoping interengagement on an axis normal to the abuttingplane of said shell flanges and forming a sliding friction fit therebetween, said outer core tube having abutments at theends thereof and'adapted to have a cordV wound thereon.

4. A cord holder comprising a pair of complemental opposed substantially semi-spherical shells, a peripheral radial flange formed 'on each shell abutting each other, a core tube within one cally opposed like securing means provided on the lia-nge of the shell carrying said outer core tube.

5. A cord holder comprising a pair of complemental opposed substantially semi-spherical shells, a peripheral radial flange formed on each shell abutting each other, a core tube within one shell adapted to have a cord wound thereon, a core tube on the other shell telescoping Within said first mentioned core tube and having a sliding friction fit therein whereby to maintain said shells in assembled relation, a pair of diametrically opposed lips formed on the iiange of one of said shells each adapted to receive therein a portion of said cord, a spring clip for each lip pivotally connected to said flange for movement parallel to the plane thereof and normally extending across its associated lip in frictional engagement with said flange to clamp the cord portion seated therein against movement, and a pair of diametrically opposed slots formed in the flange of said other shell each adapted to accommodate a spring clip When said flanges abut each other.

6. A cord holder comprising a pair of complemental opposed' substantially semi-spherical shells, a peripheral radial flange formed on each shell abutting each other, a core tube Within one shell rigidly secured thereto, an outer core tube within the other shell and rigidly secured thereto, said core tubes being each of a greater axial length than the depth of said shells and in co-axial alignment and telescoping interengagement on an axis normal to the abutting plane of said shell flanges and forming a sliding friction fit therebetween, said outer core tube having abutments at the ends thereof and adapted to have a cord Wound thereon, a pair of diametrically opposed lips formed on the flange of one of said shells each adapted to receive therein a portion of said cord, a spring clip for each lip pivotally connected to said ange for movement parallel to the plane thereof and arranged to normally extend across its associated lip in frictional engagement with said fiange to clamp the cord portion seated therein against movement, and a pair of Vdiametrically opposed slots formed in the flange of said other shell each adapted to accommodate a spring clip when said flanges abut each other.
