s claims. (c1. 24a-12s) .This inventionl relates .to `reels and'rnore `par- '"tieularly to light `Weight .metal reels having -annu.-

` ylarly shaped hollow heads. y

' In-accordancewith oneembodimento. thexinventiOn, pa. reel `is providedhavingf a cylindrical drum1tofwhich-isfwelded, ateach'end thereof, an wannularlyshaped -hoilow head comprising an' in- I ner annular member: .having/an outer lperipheral `yange rnundedfoutwardly :to abutwlantlnwardly extending..innerrperipheral ange of an` louter dish-,shaped annular 4member having aninner annular v,flange rounded 1 inwardly- .to a point substantially .in Lline. with: the, abutting outer peripheral dianges ofi the,` two members andithen-extended straight toabutfthe inner annularedge 'off the "nrst member, which isdisposed at rightl tangles thereto, the two members being ffcontinuously welded `together at their outer and'inner :lines of' juncture and similarly welded to the @periphery :of the drum attwo spacediines vof welding, one of the 4latter vlines of welding being .substantially inflinewith the outer peripheral-line of welding of the abutting lflanges `of "the two members.

Otherobjects; and features of the invention will become apparent from the following detailed de scription taken in conjunctionvwith the accomfpanying drawing, in which:

Fig, 1 is a side elevational view, partly in section, of a reel embodying theufeatures of the invention;

Fig; 2 is an enlarged fragmentary cross-sectional'view-taken-on the line 2-2 of Fig. A3; and

Fig. 3'isV a fragmentary end elevational Aview of the reel.

Referring to the drawing, it will be observed that a reel embodying the features of the present invention comprises a pair of heads Ill-I0 secured to oppositeends of a straight cylindrical drum I I having, in the present embodiment, open ends,y the drum being formed from a sheet of metal cut to theproper size and rolled into a cylinder with its edges abutting and welded together, as` indicated at I2. The reel is of all metal constructionand may be used to support cable or other strand material which is wound upon the drum II.

` Each of the reel heads I0 comprises annularly shaped inner and outer sheet metal members I3 and I4, respectively, the members being so shaped and cooperating when assembled and fixed to each other to form a hollow head, .as clearly shown in Fig, 2. The inner member I3 has its outer peripheral yportion bent outwardly and rounded to formv a s-ilange I'I which .extends from a main flat portion i8. Spaced `from and parallel to the main flat portion I8 of the member I3 isaamain ilat portion lI9 of the outer member I4,

`which hasn its outer peripheral portion bent in- Wardly and rounded to form a flange 20 which, yat its edge, meets the corresponding'edge of the `:flange I' of the inner `member I3. `The flanges Iland 2li of themembers I 3 and I4, respectively,

.'have'thelr opposed `edges abutting and thus cooperate to form an annular lrim having arounded yor `semi-,circular cross-section at its' periphery,

the ,members being welded together where `their annular flange edges abut t0 form a continuous yweld2l.

`Atgits inner peripherallportion, the outer member I4 .is bent inwardly and rounded to form a flange'tz 4which extends from its main flat portionA la to a` point 2.4 substantially in line with the welded annular ange edges of the members i3 and I4. `From this `point 24, the Yflange 22 .extends straigh'ttor parallel to the axis of the drum ,'I l and ,inV abutting `relationship with the yperipheral surface of the drum and also with the inner peripheral edge surface of the inner Amember I3 withits annular end edge terminat- :ing with the plane of the inner surface of the Vnianilat portion I8 of the member I3.

The point 24 of the flange 22, inaddition to being inwalignment with l:the welded ange edges, is substantially v`in alignment with the annular'end I erige` of the drum Il( At the juncture of the flange 22 `chtite-member` I4, with the inner `peripheraledge :surface of the inner member I3, the'headmembers land I4 are welded together 'and also tothe Yperipheral surface of the drum I I to form a continuous weld 25. Each head I0 is also welded to the outer peripheral edge of the drum II to form a continuous weld 2B.

From the above description of the outer head member I4, it will be apparent that it is of annular dish-shaped formation with its inner ange 22 of greater depth than its outer flange 20, whereby it may abut and be continuously welded at 425 tothe inner annular edge of the main flat portion I8 of the inner head member I3 and to the drum II. This arrangement, taken with the continuous weld 2| provided at the annular abutting outer peripheral edges of the flanges I1 and 20 of the two head members, results in a reel provided with hollow light-weight heads having a high degree of strength commensurate with v other t provide a single unobstructed space irl-,-

'reelcomprising a cylindrical metal drum having open ends land annular hollow heads at opposite ends 4of said drum, each of said heads member, the members being bonded togetherlat i their abutting lines of juncture. i

2. A reel comprising a drum and an annula 'hollow head on said drum, saidy head comprising a rounded inner peripheral flange terminating in a straight portion in engaging relation with the `periphery of and being secured to said drum and abutting the inner peripheral edge of the inner member, the members being bonded together at their abutting lines of juncture.

3. A reel comprising a cylindrical drum having open ends and an annular hollow head on said drum, said head comprising solely a pair of inner and outer annular metal members arranged in spaced relation one to the other to provide a single unobstructed space in the head and having outer peripheral flanges directed toward and abutting each other at their edges, said members having plane surfaces for the greater portions of their areas, said outer member having a rounded inner peripheral flange terminating in a straight portion in engaging relation with the periphery of the drum beginning at an annular end edge surface of and being secured to said drum and extending inwardly from said drum edge surface to abut the inner peripheral edge of the inner member, the members being bonded together at their abutting lines of juncture.

A reel comprising a cylindrical metal drum having open ends and an annular hollow head on said drum, said head 'comprising solely a pair of inner and outer annular metal members arranged in spaced relation one to the other to provide a single unobstructed space in the head Vand having outer peripheral flanges directed toward and comprising solely a pair of inner and outer annular metal members arranged in spaced parallel relation one to the other to provide a single unobstructed 'space in the'head and having similarly rounded y'outer peripheral flanges directed toward and abutting each other 'a't their edges to form a rim of semi-circularjcross section, said members having plane 4surfaces for the greater portions of their areas, said'outer member having an inner peripheral flange engaging the periphery of the drum beginning atan annular end edge of said drum and extending inwardly from said drum edge to abut the inner peripheral edge of the inner i member, the members being continuously welded together at their abutting lines of juncture andtov the periphery of said drum at the inner edge of said inner iiange and to the periphery of said drum at its annular end edge surface.

16. A reel structure comprising al drum and annular heads fixed to the drum, each head comprising solely an -annular sheet having the area thereof adjacent the periphery bent in an arc, and a second annular vsheet spaced from the rst-mentioned sheet to'provide a single unobstructed space in the head, said second sheet havling its inner 4and outer areas bent in an arc to 'meet the edges of the rst-mentioned sheet, and

continuous 4welds formed at the inner and outer points oijuncture ofthe sheets to join the sheets into a unitary hollow head.
