Feb. 17, 1931 w. c. MILLS 1,792,753
SPOOL Filed July 7. 1928 A WALLAOE Patented Feb. 17, 1931 O." MILIQs, F nooxronn, ILLINO S, AssIGnoR T0 J. I. GLARKMANUFACTUR- Ineoo., or ROCKFORD, ILLInoIs', A CORPORATION OF ILLINOIS SPOOL Applicationfiled Ju1y-f7, 1928. Serial No. 291,074.
The invention has-referenceto spools 0fthe type comprising a tubular core'with substantially flat sheet metal heads secured upon opposite ends of the core. Thecoreiof such a spool. is commonlymade from a flat sheetof metal, and in fastening the heads onto the ends of the core the .joint formed between the meeting edges of the sheet constituting the'c'ore are aptto present sharp cutting I securing the head onto the-core while atthe same-time'presenting a smooth uninterrupted surface" at the end of the core. v
A further object is to provide a construc tion for the spool rendering it possible to manufacture fthe'same on an economical basis. r 1' 7 he foregoing objectsytogether with other and ancillary advantages are'attained by the construction and arrangement shown in the accompanying drawings forming part hereof, it being contemplated however, that vari ous changes may be made by those; skilled in the art withoutideparting from the spirit and scope of the invention.
In the drawings: V 5 Figure "1 isa-lside elevation ofa spool of the.characterreferred tol l Fig. 2is a central.vertical"sectional view through one end of thefspool showing the parts assembled, but before the forming or interlocking operation.
Fig. 3 is a similar viewon a larger scale from a flat sheet of metal rolled into tubular form, the opposite ends ofthe sheetmeeting j Each head 8 is formed from a sheet of metal centrally apertured so as to form a fiat ring or disk the outer peripheral edge of which may be curled. as at 10 for finishing and strengthening purposes. The heads are customarily lithographed for. purposes of identifying the manufacturer or to convey any other desired information, this, being done before the heads are assembled onto the endsrof the core.
Near each end the core is shaped to provide' an outwardly extending beadll leaving an end portion 12 projecting beyond the bead.
Fitting snugly over the end portion is a U- shaped part of an annulus 13 formed from a flat sheet of metal and having prior toassembly an inner peripheral leg 14 and an outer peripheralleg 15. The inner leg preferably extends inwardly into the core beyond the bead 11 and the outerleg preferably terminates just short of the bead and has, in
the present instance,'formed thereon an outturned flange 16.
Eachof the spool heads Shas an internal diameter such as'to fit rather snugly about the annulus 13 and more specifically about the outer peripheralleg thereof, and in the initial assembly of the parts the head is arranged to seat upon the outturned fiange 16.
With the parts thus assembled (Fig. 2)
the fastening ofthe heads onto the ends of thecore is accomplished by bending each annulus together with-the end portion 12 there- "in'; outwardly fiat upon the head 8; as shown in 8; while at the same timecompressing the-parts longitudinally of the axis of the core so as to flatten the bead and securely clamp the parts together. 1
It will be; observed from' Fig. 3 that by the constructionprovided an outwardly opening groove is" formed between the flange 16 V and the peripheral leg 15of the annulus, in-
which the inner peripheral edge of the head is securely clamped. Similarly the end portion'l2 of the core becomes bent to form an outwardly opening groove to receive the outer leg ofthe annulus doubled upon itself, withthe head therebetween as above set.
gether through the medium of the annulus,
all danger of stressing, breaking or otherwise injuring the metal of the head and of the annulus is avoided. This is especiallyimportant from the standpoint of economy in manufacture in that it enables the use of ordi-.
nary commercial stock sheet metal, simplifies the assembling and forming'opera ion, re-- duees the amount of scrap produced, insures against distorting the printed or litho graphed surfaces of the heads, and avoids the necessity for using a lubricant on the dies where an excessive amount of stressing must occur, it being necessary subsequently to remove such lubricant.
If desired the heads may in the forming operation be ofi'set as at 17 (Fig. 3) to receive the flattened head 11, the inner face of the latter being substantially flush with the inner face of the head.
As shown in Fig. 4:, the annulusmay in the case of some spools have formed integral therewith an end wall 18. This wall in the present instance is shown connected to the inner leg 14 of the annulus by an inturned portion 19 and the end wall is disposed substantially in the plane of the curl 10 at the edge of the head 8. The wall 18 is centrally apertured to receive an inner tubular memher 20 the ends of which are flanged outwardl v as at 21 so as to engage with the edges of the aperture in the'wall. This permits the mounting of the spools when desired onsuitable pivotal supports and the portion of the end walls in the plane of the head is desirable in that it permits oi the use of short end pivots which ofler very little obstruction to the placing of the spool on the pivots.
I claim as my invention:
1. A spool comprising a core formed from a flat sheet of metal and bent into tubular form, heads at opposite ends of the core, each end of the core being constructed to form a shoulder and an end portion projecting from the shoulder, an annulus having a U-shaped portion fitting snugly over said end portion,
said head comprising a centrally apertured disk encircling the annulus and held by said shoulder against movement inwardly of the core, and the end portion of the core together with said U-shaped portion of the annulus being bent outwardly with one leg of said U-shaped portion bearing directly on said disk.
2. A spool comprising a core, an annulus having a portion U-shaped in form and fitting over one end of the core with an inner leg extended into the core and anouter leg havingan outturned flange, and a head in the .formed from a flat-sheetof metal, an annulus having a portion U-shaped in form and fitting over one end of the core, said core having a bead thereon near said end, and said U-shaped portionhaving aflange adjacent said head, and a head comprising a disk centrally apertured and adapted to rest upon said flange, said U-shaped portion of the annulus together with the end portion of the core therein being bent. outwardly upon said head soasto clamp the same together with said flange upon-said bead.
4. A spool formed of sheet :metal and comprising a core, a head,.and an annulus interlocked with the head and the; core, saidcore being bent to provide an outwardly opening groove to receive a portion-of the annulus, and said portion of the annulus in turn being shaped to provide an outwardly opening groove to :receive the inner peripheral edge ofthe head.
5. A. spool comprising a core, a head, and an annulus interlocked with. the head and. the core, said annulus having a part bentto. form an inwardly openinggroove to receive the end portion of the core and an outwardly opening groove to receive the inner peripheral edgeof the head.
6. A spool having a core, a head on one end of the" core, and an annulus connecting the head to the core,said annulus havinga por- .fiat sheet of metal bent into tubular form,
means forming a. shoulder near the end of the core, a head in the form ofa centrally apertured disk, said Core having its end bent out wardly, and an annulus. having a portion, clamped directly between the head and said outwardly'bent portion of the core and curled around the end of the core so as to extend a substantial distance into the core, said head being held against movement inwardly of the core by said shoulder.
In testimony whereof, I have hereunto affixed my signature.
