10 Claims.
The invention pertains tok spools or reels of the type embodying a tubular body usually constructed of sheet metal and having'a pair of heads each composed of one or more sheetmetal plates and secured upon opposite ends of the body.
The primary object of my invention is to provide a spool of this character in which the heads are secured on the ends ofthe tubular body in a manner' such as to lend strength and rigidity to the connection as well as to present a neat appearance.
A common method of fastening a spool head on the end of a tubular body consists in providing a circular series of lugs or tabs formed on the end of the bodyY and bentl into engagement-with'a head plate to secure the latter in position. The
present invention involves such a method ofv fastening a head on the tubular body, andv a further and more speciiic object thereof is. to improve this method of fastening by the provision of an annulus bent. into engagement With the fastening lugs so yas to bind or clamp them firmly upon the head plate and at the same time entirely conceal the same.
The objects of the invention thus generally set forth, together with other and ancillary advantages are attained by the construction andv ar rangement illustrated in the accompanying draw-f ing forming part hereof, wherein:
Figure 1 is a fragmentary sideelevational view of a spoolwith one end portion shown in section to illustrate the construction employed.
Fig. 2 is a fragmentary transverse sectionalA 3 Fig. 1,
modification.
Fig. 6 is a plan view of a spacer ringemployed in the form shown in Fig. 5.' A' j The spool comprises a tubular body`7 having heads'8 secured at opposite ends thereof. The body 7 is formed from a flat sheet of metal bent into cylindrical form and out at opposite ends to form tabs or lugs 9 spaced a short distance apart in a circular series. Each head comprises a circular plate or disk 10 havingits peripheraledge curled as at ll'. Spaced radially inwardly from said peripheral edge is a circular series of slots l2 adapted to` receive the lugs 9.
The lugs 9 are of a length substantially greater than the thickness of the disk 10 so that when Fig. 5' is a similar View illustrating another the lugs are entered through the slots with the disk seated upon the end edges of the body formed between the lugs, the latter will project a substantialdistance beyond thedisk. The lugs are thus capable of being bent transversely of the body into engagement with the disk.
Forvthe purpose of clamping the securing lugs 9v firmly upon the disk and at the same time concealing the lugs, thehead is constructed to provide an annulus 13.` This annulus in the -embodiment shown in Fig. 1 is made integral with the disk 10 by forming therein an outwardly eX- tending fold Whose open end is disposed within and closely adjacent to the end of the body. The lugs 9 are thus disposed adjacent the outer leg of vthe ,fold so that by bending the latter outwardly and downwardly toward the disk the lugs are bent iiat upon the disk'in underlying relation to the annulus. t
A n end closure plate 14 for the tubular body comprises injthis instance a disk'formed integral with the annulus and hence with the disk 10. v Thus the inner leg of the fold constituting the annulus may be extended inwardly to form the plate 14 which isv centrally apertured to receive the endofan inner core 15 having, its ends curled outwardly into engagement with said end plate.
I have found that the annulusthus provided serves effectually to bind the lugs 9 rmly against the disk 10 1 so as to insure that the head shall be fastened securely on the end of the body with the lugs concealed from view to the end that the spool shall present a neat appearance.`
I In theembodiment illustrated in Fig. 4, the
head-comprisesfa circular plate or disk 10 and a separately formed end closureplate 14'. kThe disk 10*l terminates in a ange llwithin and concentric to the end of the body, and an annuluslB' is in the form of a fold formed integral with the plate 14'. The annulus in this instance re'ceives-both the lugs 9 and the flange, so.v` that the'free edge of the annulus is curled around:` theflange 16 and interlocked between the lugs and -thedisk 10 at a point adjacent the body'l., The end closure plate `le may be cen-` trally apertured-to receive the end of an inner core 15' as in the case of the form shown inv Fig. l.
As shownA in Fig. 5, the invention is applicable also to a spool construction in which the head comprises a face plate 17 and a backing plate 18 separated at a point adjacent the body by a spacer member vin the form of a ring 19 encircling the body, notches 20 being cut in the ring to receive lugs 9. An `annulus 13a is formed integral with the face plate 17 in a manner similar to the annulus 13 (Fig. l), and this plate is extended inwardly to form an'end closure plate 14n3L as in 'the construction shown in Fig. 1. The two plates The double end wall provided in this instance.
results in a more rigid construction, especially when used in connection with the spacer ring combined with the clamping action of the annulus on the securing lugs 9.
I claim as my invention:
