` s claims. (c1. zia-12s) This invention relates to a spool or reel of the type formed of sheet stock and is a continua-` tion in part o f my copending application, Serial No. 190,894, filed February 17, 1938, now Patent No. 2,258,580.

The invention has for one of its objects to provide a spool or reel which will have unusually strong heads so that when copper wire is reeled upon the spool and heated for annealing, whereby there is provided considerable expansion because of the greater coeicient of expansion of the copper than the gsteel of the spool, the strains exerted will be resisted and the heads will maintain their shape in planes at right angles to the axis of the barrel.

of wire into crevices I have so arranged that even though there opened up. AndI Another object of\the invention'is the provision of a structure which will so. support the stresses as to remain mit of high speed drawing without wobbling or chattering of the spool on its supports.

Another object of the invention. is to prevent the entry of wire into the seam between the barrel and the. flange of the head which contacts the end of the barrel.

Another object of the'invention is to so relate the head and the barrel that, even though there be accomplished.

With reierence,to the drawings, I0 designates concentric whereby to per- -the barrel be movement of the head relative to the Abarrel in a direction axially of the barrel, still no seam will be opened up into which wire may enter.

With these and other objects in view, the invention consists of certain novel features of confully described, and

struction, as will be more the appended claims.

particularly pointed out in In the accompanying drawings: v Fig. 1 is a sectional view of a spool embodying this invention;

Fig. 2 is an exploded view of the several parts which go to connectvthe head to the spool;

illustrating a diner-- Fig. 6 is a sectional view ent manner of welding certain of the parts in position. i, vIt is round in the use 'or spools such as are used in .annealing copper wire that when the loaded spoolis` heated the expansion of the lcopper wire than the expansion o1 the steel of the spool causes tremendous stresses to be exerted on the heads oi.' the ing or the heads o! the spool or of the head axially along the barrel. Such axial movement in some cases may cause lan opening spool and often a warp-Y some movement of the joint so that wire on the spool may enter the same; and in order that the wire may be. drawn at high speeds it is essential that the spool be accurate and concentric with the center hole that' the strains may spool from becoming eccentric-or any parts from i moving beyond the tolerance allowed for high speed productionpand the following is a more detailed description of .the of this invention, illustratingv the preferred means by which these advantageous results may or the spool and Il the heads of the spool which are formed from sheet stock as -shown more fully in Fig. 2. There is a center hole l2 in the head Il of a'size substantially the size of the outer diameter of ther barrel I0 so that the barrel I0 will extend into the hole l2 and through the head substantially the thickso that the end I2 of the barrel will lie substantially ush with the outer surface Il of the head I l.

The head and barrel are secured inthis relative vposition by a reinforcing plate sleeve It extending inwardly therefrom and of a ,ly of the end 22 of the curved surface 3l o! diameter to closely nt the inner surface l1 of the' barrel, while the plate I5 engages the outer surface Il of the head Il. Thus, there is formed about the juncture or seam the barrel l0 an L-shaped whichwhen serves to maintain these two tion.

The sleeve' I. may terminate as shown in Fig. '4, or it may extend radially inwardly as at Il to the center tube reinforcing member at 2l along the .center tube to be engaged at its end by the rolling outwardlyand backwardcenter tube as illustrated sleeve may extend radially inshown in Figs. 1 and 2,' thence in Fig. 5; or thev wardly as at 24, as axially outwardly as at O wardly as at 26 and then turning inwardly, again axially as at 2l to engage theabutment 28 raised at intervals from the stock ofthe tube I9 for such abutting relation, while the thinned edge of this tube I9 may be rolled outwardly, about the thev rtions 2!k as atl to lock this reinforcing member centrally in present embodiment i of the head Il and to the head and the barrel in this relative posi,-v

25, againl radially inposition. The outer surface 32 of this portion 23 is in substantially the same plane as a tangent 33 to the rolled edge 34 at the periphery of the head so that the spool may be set upright upon its end and may rest upon the surface 3 2 and edge 33 for better supporting of these spools in this position, such, for instance, as stacking a sexies of spools one on top of the other endwise.

In order to secure the reinforcing member to the barrel and head, I will weld the same to .the barrel through the sleeve portion IB as indicated at 35 and then the reinforcing member able weld as at 36.

The weld 35 may take the form of a continuous resistance weldas shown in Figs. 1, 4, and 5, or the' form of a series of spot welds as shown in Fig. 6 as at 31; while the weld at 36 securing the plate Il to the head Il may be in the form of a continuous resistance weld or preferably in the form of spot welds in staggered relation about two diiferent'radii from the center axis as illustrated in Fig. 3.

The foregoing description is directed solely towards thevconstruction illustrated, but I desire it to be understood that I vreserve the privilege will weld the plate I of to the head by a suitof resorting to all the mechanical changes to which the device I claim:

1. In a reel or spool of sheet metal a head having a central opening therein oi' approximately the size of the outer diameter of the barrel and with the surface defining said opening relatively smooth and unbroken, a barrel extending into saidopening, a central tube, an end plate abutting the outer surface of saidvhead and having a ilange extending into the opening is susceptible.

e ing relatively in said barrel along said barrel and then extending radially inwardly, then outwardly axially of the barrel, 'then radially'inwardly to engage said tube, and a weld located between said flange and barrel to hold said head and barrel in aslsembled relation.

2. In a reel or spool of sheet'metal a head having a central opening therein of approximately the size of the outer diameter of the barrel and with the surface defining said opensmooth and unbroken, a barrel extending into said opening, a centralvtube, an end plate abutting the outer surface of said head and having a flange extending into the opening in said barrel along said barrel and then extending radially inwardly, then outwardly axially of the barrel, then radially inwardly to engage said tube, a weld located between said ilange and barrel, and a weld located between said plate and head to hold said head and barrel in assembled relation.

3. In a reel or spool of t metal having a head at each end thereof, each head having a central opening therein approximately the size of the outer diameter of the barrel and with the edge of the opening smooth and unbroken, a barrel having continuoussurfaces at the end portions thereof extending into said openings, and plates abutting the outer surfaces of said .heads and each plate having a continuous unbroken circular flange extending into the opening of the barrel, the free ends of said flanges being spaced from each other and a weld located between each oi said flanges and the barrel and about the periphery of the barrel to hold said heads and barrel in assembled relation.
