Description

July 1Q, 1934 P. T. KELLEY SPOOL Filed March 24, 1955 IN VENT OR ORNEY Patented` July 10, 1934 UNITED STATES PATENT OFFICE 12 Claims.

This invention relates to spools, reels, bobbins, or like winding devices.

An object of this invention is to provide a spool which is economical to manufacture and durable in use, and yet be so constructed as to be light in weight.

Another object of this invention is to provide a construction for a spool so that the core and disks or anges may be made of fibrous mate- 10 rials, such as fibre or impregnated paper.

A further object of this invention is to produce a spool or the like. which has no rough parts or crevices on or into which fine threads may extend to be cut or torn thereby.

Other features and advantages will hereinafter appear.

In the accompanying drawing- Figure 1 is a perspective view of a spool made in accordance with this invention.

Fig. 2 is a longitudinal sectional View of the spool shown in Fig. 1.

Fig. 3 is a sectional view showing the barrel, end ange, and uniting parts expanded.

Fig. 4 shows' the parts brought together prior 25 to spinning or deforming the end flange hub.

Fig. 5 shows the end flange hub spun into operative position.

Fig. 6 is a view similar to Fig. 5, but showing the structure modified.

Fig. 7 is also similar to Fig. 5, and shows another modied form of the present invention.

Fig. 8 is a perspective view of part of the retaining flange of the device shown in Fig. 7.

As shown in the accompanying drawing, the 35 spool of the present invention comprises a barrel 10 which may, and preferably is, made of impregnated paper so as to be relatively light and inexpensive. The same is true of the end-disks 11, although, of course, both the barrel 10 and the end-disks 11 may be made of fibre, wood, or other suitable material.

When impregnated paper or fibre is used for the barrel and end-disks, the problem of securely fastening the end-disks on to the barrel is quite different from when these parts are made of other materials, and it is the solution of this problem which is an important feature of the present invention.

As shown in the accompanying drawing, the barrel 10 and end-disks 11 are secured together by metal fastening members 12 (Figs. 2 to 5), 12a

(Fig. 6), orv 12b (Fig. 7), the latter two gures showing modifications of the invention shown in Fig. 2.

The fastening vmember 12 is made of sheet metal, preferably brass, stamped and drawn so A as to have spaced concentric cylindrical portions 13 and 14, the cylindrical portion 13 being the inner one and the cylindrical portion 14 being directly outside the portion 13. These portions are connected by a Wall 15 and form between them a laterally open annular groove 16, see Fig. 3. This groove is shaped to receive the end 17 of the barrel 10 so that the inner surface of the outer cylindrical portion 14 engages the outer surface of the end 17 of the barrel while the outer surface of the inner cylindrical portion 13 projects into the tubular barrel 10 for a substantial distance and engages the inner surface of the barrel.

When the members 12 have been applied to the barrel 10 in this manner, they may be anchored thereto by a spun annular rib 18 as shown in Fig. 5, or prongs 19 may be lanced from the cylindrical portion 13 so as to project into the material of which the barrel 10 is formed, as shown in. Fig. 6. After the member 12 has been placed on the end of the barrel 10, the end-disk or wheel 11 may be slid over the outer cylindrical portion 14, and for this purpose the end-disk has a central aperture 20. Preferably, the aperture20 is of such size as to slidingly fit over the portion 14 which forms a hub for the wheel or end-disk 11. The disk 11 may be moved inwardly over the end of the barrel until its inner face engages a radial flange or disk 21 on the inner end of the portion 14,' and when it does so the connecting portion 15 of the member 12 extends beyond the outerface of the disk, as shown in Fig. 4. After this is done, the portion 15 of the member is deformed and pressed toward the end v17 of the barrel 10 and outwardly so as to overlie an outer portion of the disk 11, as shown in Figs. 5 and 6. This may be conveniently done by spinning the material of the portion 15 of the member l2 and fiowing it over against the outer face of the wheel 11, and it is convenient to have the disk 11 beveled as at 22 to receive the material spun over. This securely crimps or binds the wheel to the member 12 between the flange 21 and the spun-over flange or 100 i shoulder 23.

When the material is hard or brittle, it is preferable that a split ring 24 be inserted in the recess -16 before the end 17 o f the barrel 10 is inserted.

As shown in Fig. 4, the ring will take a position against the inner surface of the outer cylindrical portion 14 and, when the spinning and pressing operation is performed, the metal will bend around the ring which thus forms an anvil and prevents the metal from cracking. The pressure in the corner of the end 17 and extend over into the spun flange 23.

When the material is of a softer nature and not so likely to crack, the ring 24 may be dispensed with as shown in Fig. 6.

In order to preventl fine thread or wire which may be wound on the spool from entering between the disk 21 and the inner surface of the end-disk 11, the present invention provides a. circumferential flange 25 on the end of the disk which fits into a circular groove 26 provided in the disk 1l, thus avoiding any crevices or notches into which the wire or thread might extend and be caught and broken.

By having the portion 15 extend through the wheel, it may be utilized as a thrust bearing on which the spool rotates when supported on a vertical spindle.

In the modification of this invention shown in Fig. 7, the outer cylindrical portion on the fastening member is dispensed with and instead the end-disk 1l slides directly upon and in contact with the end of the barrel 10. This movement of the disk 11 inwardly on the barrel is limited by a sleeve 27 which is slid over the barrel 10 before thedisks 11 are applied. The disk is anchored to the barrel by a flange 28 o n the member 12b which4 extends over the end 17 of the barrel and also over a portion of the outer face of the disk 1l.

'I'he flange 28has to extend farther over the central aperture of the disk 1l in the form shown in Fig. 7 because of the omission of the outer cylindrical portion 14. At its end, the flanga28 is preferably provided with a circumferential ange 29 fltting into a groove 30 in the outer surface of the disk 11. To close the space between the end of the sleeve 27 and the inner surface ofthe disk 11, there is provided a ring 31 of cloth, felt, or other soft material.

The member 12b shown in Fig. 7 may be fastened to the barrel 10 by an annular rib such as the rib 18 shown in Fig. 5, or by the lanced prongs 19 as shown in Figs. 6 and 7.

The circumferential flange 29 may, as shown in Fig. 8, be provided with serrations or teeth 32 adapted to penetrate the material of the disk in the groove 30, and thus keep the end-disk 11 from rotating relative to the barrel 10.

Within the scope of this invention, bearing portions may be inserted within the members 12 in any suitable manner. As shown, however, the bearings for the spool are constituted by cups 33 which may be slid into the inner cylindrical portion 13 of the member 12 until they are substantially flush with the portion' 15 of the member 12.

Each cup 33 has a central aperture through which extends an end of a sleeve 34 which may be made of sheet metal rolled into` tubular form. After the sleeve is infserted through the cups, its ends 35 may b e spun over' as shown in Fig. 2` To hold the sleeve against moving back and forth relative to the cups when, due to differences in materials the barrel 10 expands and contracts differently from the sleeve 34, one end of the sleeve 34 is provided with a spun shoulder v36 engaging the inside surface of o ne of the cups 33.

The members 12, 12a and 12b are provided with central apertures 37 through which the sleeve 34 extends.

' Variations and modifications may be made within the scope of this invention and portions of the improvements may be usedrwithout others.
