Patented Mar. 26, 1940 UNITED STATES SPOOL Bernard C. Johnson, Libertyville, Ill., assignor, by mesne assignments, to Houdaille-Hershey Corporation, Detroit,
Michigan Application March 19,
4 Claims.
The present invention relates to an improved metal spool construction and has for a primary object the provision of a construction which enables the economical manufacture of an excep- 5 tionally strong spool from relatively light material.
A further object of the invention is to provide an improved spool having a barrel with double walls which are integrally formed with the end head flanges, and in which the flanges are so constructed and interconnected as to form an exceptionally strong head structure.
Another object of the invention is to provide an improved construction which is of such a nature that it enables the spool parts to be assembled in proper relation and then simultan- `ously secured in assembled relation by a single brazing or welding operation.
Still another object is to provide in a spool construction improved means for reenforcing the spool barrel in a circumferential direction between its ends,
Other objects and features of the invention will more fully appear from the following detailed description, taken in connection with the following drawing which illustrates the preferred embodiment thereof, and in which:
Figure 1 is a sectional view taken through a spool embodying the features of the hereindescribed invention;
Figure 2 is a fragmentary end view of the same showing the reenforcing ridges in the outermost flange of the head structure; and
Figures 3 and 4 are fragmentary sectional views illustrating alternate forms of construction at the telescopic joint of the spool barrel.
As shown on the drawing:
In the illustrated embodiment of the hereindescribed invention, it will be noted from the disclosures in Figure 1 that the' spool in its broad aspects is of the usual construction containing a barrel, generally indicated at I0, which is associated at its ends with heads generally indicated at II and I2.
More specifically, the barrel of the spool is Mich., a corporation of 1938, Serial N0. 196,811
the two sections ofthe joint will be substantially iiush as shown. y 4
The innermost shell I4 is likewise composed of two sections indicated at Ma and Mb. 'I'hese two sections are similarly telescoped at their in nermost ends to form a joint, and the joint end of section Mb is expanded substantially the thickness of the material in order that the innermost surfaces of the inside shell I4 may be substantially flush at the joint, this joint being indicated at I6.
At the joined ends, it will be noted that the end margin of section I3b is inwardly deflected to form a circiunferentially extending ange II y which may be additionally deflected at its innermost edge as shown at I8. Section Mb also has its end margin outwardly deflected to form a circumferentially extending flange I9. These flanges I'I and I9 operate to circumferentially reflange 2I in surface engagement therewith, the
flange 2| being integrally formed with the section I4b at its outermost end. T he peripheral edge of flange 20 is outwardly turned to form a bead 22 which engages and anchors the flange 2I at its peripheral edge and serves to initiallyA hold'the sections I3b and I 4b in proper spaced relation.
It will be noted that the innermost ange 20 provides a smooth end surface for an abutment of wire or other material which is wound on the spool and that the beaded edge prevents cutting the material during the drawing operation in thecase of wire. f
In order to further strengthen the head conwith raised radially extending reenforcing ridges 23 which are spaced from the associated surface or ange 2li. Between these ridges are surfaces 24 which lie in the same plane and are in surface engagement with the adjacent surface of ange 20 for a purpose which will hereinafter be explained.
If desired, two of the diametrically disposedl ridges may be provided at their innermost ends with openings 25 for receiving driving studs for structions, the outermost flange 2l is provided f rotating the spool during the winding of wire or other material thereon.
While these ridges may be of any desired conguration, it is preferred to have the ridges of greater depth toward the center of the spool and gradually taper olf in depth toward the periphery of the spool, terminating in the plane of the surfaces 2li where engaged by the circumferentially extending bead 22.
In the actual construction of the spool parts, which are only four in number, the barrel sections with their integrally formed end flanges are drawn or otherwise formed from a at sheet in which the shell sections at their innermost ends are entirely closed. That is to say, the portion, for example, forming the flange l1 would extend clear across and form in effect a bottom. This bottom is then partially removed to provide the opening 26 and leave a circumferentially extending iiange. In the case of the section shown at MIJ, the bottom is entirely lcut out and the edge then deflected outwardly to form the ange I9.
It will be evident that in utilizing this construction that anges of diiferent shapes may :be easily provided at the center ofthe barrel. I have shown in Figure 3 an alternate flange construction il which does not have its innermost edge deflected as shown in Figure l..
Of course, if desired, the bottoms of the sections may be entirely cut out to leave unflanged edges at the joints as shown in Figure 4, although in this case the joint is not reenforced to quite the saine extent since the strengthening in this case results merely from having` a double thickness of material in joint.
Having the parts assembled as shown in Fig ure l, the telescopic joints l5 and i6 and the areas 2d in surface engagement with the anges 2i) are secured together in any well known. manner,
but it is prei erred to braze these parts together either by placing brass shim stock between the surfaces, or by copper plating. The surfaces may be united then by subjecting the entire spool to suficient temperature to cause the brazing metal to flow.
From the foregoing description, it will be apparent that the present invention provides an improved spool construction which enables the economical manufacture of an exceptionally strong spool from relatively light material; a spool construction in which the barrel is double walled and has integrally formed head iianges at its ends, these langes being so formed and interconnected as to provide an exceptionally strong head structure: which enables the spool parts to be assembled in proper relation and then simultaneously secured in assembled relation by a single brazing operation; and which utilizes a novel reenforcing construction for the barrel in a circumferential direction between its ends.
It is, of course, to be understood that although I have described in detail a preferred embodiment of my invention, the invention is not to be thus limited, but only insofar as dei-ined by the scope and spirit of the appended claims.
I claim as my invention:
l. In a spool construction, a double walled tubular spool barrel, said walls being concentrically disposed and spaced apart and each having both its end margins deflected to form anges at the respective ends of the barrel, all of said flanges extending outwardly past the outermost of said walls and the anges at each end of the barrel having portions in surface engagement with each other, a telescopic joint in each of the barrel walls disposed between the barrel ends, a circumferential flange extending inwardly from the outermost wall at its joint, a circumferential flange extending outwardly from the innermost wall at its joint, and means securing the flanges at each end of the barrel together in surface engagement.
2. In a spool construction, spaced end head flanges, a tubular barrel interconnecting said anges, said barrel having double walls in spaced parallel concentric relation, and a lap joint in each of said walls disposed between the ends of said barrel, said lap joints having separate reinforcing flanges associated therewith and located between said double walls, said flanges extending in a direction substantially parallel with each other.
3.
