(crass-en's) 4 Glaims. 1

This invention relates-to winding spools for the reception of cord, yarn, wire, ,or other such products, and it has for itsobject the provision of a new and improved form and arrangement of parts by whicha spool or reel maybe made from a piece of stiff tough paper or other'suitable sheet material folded into shape. I have accomplished my object by the provision of parts "formed by folding a piece of sheet materialinto shape for bringing about cooperative action of the several parts with respect to bracing and reinforcing the structure so as to insure a high degree ofstrength. The means by which my objects have been attained comprise-a structure in the form .Qf acup,

with the side wall-portions at opposite sides su'bstantially parallel with each. other so as to hold in stable position successive turns of wire or the like wound about the body-of the cup.

It is another object of -the invention to improve devices of this type in sundry details hereinafter pointed out. The preferred means by which I have accomplished my object is shown by the accompanying drawing, in which:

Fig. 1 is a side face view of the preferred form of my improved spool or reel;

Fig. 2 is a face view of the blank from which my improved spool is made; and

Fig. 3 is a view of the spool as seen from the left in Fig. 1.

This application is being filed as a division of my application Serial No. 521,224, filed February 5, 1944, now Patent No. 2,432,501 of December 16, 1947.

Referring now to the several figures of the drawing, in which corresponding parts are indicated by the safe reference characters, 10 indicates a blank preferably of paper or other tough stiff sheet material, comprising a transverse base panel ii, having a plurality of side wall panels i2 extending outwardly from the sides of the transverse panel, in the arrangement shown there being six of such side wall panels; As is clearly shown in Fig. 2, the sheet material of the blank is cut out for a short distance along a circular outline at points between each of the side wall panels 12 and the transverse base panel H, so as to provide outwardly projecting lugs or tabs l3 still remaining in the plane of the transverse panel when the side wall panels are folded upwardly and inwardly into the form of a cup. Such lugs 13 are directly opposite to similar lugs l4 extending outwardly from the outer edges of the side wall panels l2.

For forming the spool from the blank Hi, the side wall panels 12 are folded" upwardly at right angles to thetransverse Panel ii, the sheet mate- .rialintervening betweenthe side wall panels being folded inwardly, at the corners of the blank seas to. provide triangular tabs 15 which serve effectively for limiting the inward movement of the side wall panels 12 with respect to each other. .After the side wall panels 12' in the operation of forming the cup reach their final positions as shownin Fig.3, the lugs It are bent outwardly into parallel position with respect to the lugs I3 so as to'bring the parts into the condition as illustrated in Fig. "1- ready to receive a winding of yarn or wire or other flexible material thereon.

the arrangement shown, the transverse panel H is provided with a central opening It for-the reception of any approved form of sup porting and driving means for the spool. The arrangement is such that when the initial turns cessive turns of the winding are kept by such lugs in approximately centered position axially.

With the triangular tabs I5 of the same width at opposite sides of the line of fold between them at the corner of the blank, each connected pair of such tabs hold the adjacent edges of the side wall panels l2 effectively in position with respect to each other so that such side wall panels are held strongly in normal angular relationship to each other as shown in Fig. 3 for providing the desired surface for winding purposes.

By the use of my improved construction, I am enabled to provide an effective winding spool of light weight but of comparatively great strength, such device being produced at low cost with a minimum of labor and attention for producing and arranging the device for use.

While I prefer to employ the form and arrangement of parts as illustrated in the drawing, the invention is not to be limited to such form and arrangement, except so far as the same may be specifically claimed, it being understood that changes might well be made in the construction without departing from the invention.

I claim:

1. A winding spool in the form of a cup folded into shape from a piece of comparatively stiff sheet material, comprising in combination a base panel, side wall portions formed integrally with the base panel on all sides of the panel and standing at right angles thereto, inwardly extending 2. A winding spool in the form of a cup folded into shape from a piece of comparatively stifi sheet material, comprising a transversely positioned base panel of polygonal form, a plurality of side wall panels formed integrally with the base panel at the several sides thereof and standing at right angles to the base panel with the edge portions of each side wall panel positioned closely adjacent to the side edge portions of the adjacent side wall panels, a pair of inwardly extending triangular corner tabs formed integrally with each other and integrally with the side wall panels at each corner of the base panel adapted by their engagement with each other normally to hold the side wall panels in operative relationship to each other, and means for holding material wound on the spool from moving axially out of position thereon.

3. A winding spool in the form of a cup folded into shape from a piece of comparatively stiff sheet material, comprising in combination a base panel, side wall portions formed integrally with the base panel on all sides of the panel and standing at right angles thereto, inwardly extending corner tabs formed integrally with the side wall portions and normally preventing the side wall portions from swinging inwardly beyond their normal positions at right angles to the base panel, lugs extending outwardly at the sides of the transverse base panel at right angles to the side wall panels, and other lugs formed integrally with the side wall panels in position to be bent outwardly into parallelism with said first-named lugs for holding the material wound on the spool from movement axially out of position on the spool.

4. A winding spool in the form of a cup folded into shape from a piece of comparatively stifl? sheet material, comprising in combination a base panel, side wall portions formed integrally with the base panel on all sides of the panel adapted to swing toward and from position at right angles to the base panel, inwardly extending corner tabs formed integrally with the side wall portions and normally preventing the side wall portions from swinging inwardly beyond their positions at right angles to the base panel so as to support a flexible member wound about said side wall portions, said flexible member serving to hold said wall portions in right angled position with respect to the base panel, and means for holding the turns of said flexible member from movement axially from the spool whereby said side wall portions may be maintained in said right angled position.
