9 Claims.

This invention relates to a spool or reel of the type formed of sheet stock and is a continuation in part of my copending application, Serial No. 190,894, led February 17, 1938, now Patent Number 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, which provides considerable expansion because of its greater co-eicient of expansion than the steel 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.

Another object of the invention is the provision of a structure which-will so support the stresses as to remain concentric whereby to permit of high speed drawing without wobbling or chattering of the spool on its supports.

Another object of the invention is the provision of a spool having the desired strength in Ythe head and yet one which will have a -seamless joint at the corner where there usually exists a seam between the inner surface of the head and the outer surface of the barrel.

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 seal the steam between the end of the barrel and the flange of the head which engages the same at spaced locations suiciently close to prevent the entry of wire into the same.

With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Fig. 1 is a sectional view through the spool embodying this invention;

It is found ln the use of spools, such as are used for annealing copper wire, that when the loaded spool is heated that the expansion of the copper wire being greater than the expansion of the steel of the spool causes tremendous still different modification of the inven- 10 is a fragmental sectional view illustratstill different modification of the inven- 11 is a fragmental sectional View illustratstill different modification of the invenstresses to be exerted on the head of the spool and often a warping of the head of the spool and an opening at its joint with the barrel which allows entrance of the wire; and in order that a wire may be drawn at high speeds it is essential that the spool be accurate and concentric with the center hole, and accordingly I have so constructed a spool that the strains may be resisted sufliciently to prevent the spool from becoming eccentric or any part moving beyond the tolerance allowed for high speed production; and

'- the following is a more detailed description of the present embodiment of this invention, illustrating the preferred means by which these Iadvantageous results may be accomplished:

With reference to the drawings, I0 designates the barrel of the spool and II the heads of the spool which are formed from a piece of sheet stock, as shown more fully in'Fig. 2, having a central hole, the fiange I3 extending inwardly about the hole and of a size to abut the end of the barrel IIl. The outer portion ofthe sheet stock head is rolled as. at I4 to strengthen the edge thereof. A sleeve I5 snugly engages the inner surface of the ange I3 and the end portion of the barrel so as to extend on either side of the joint I6 formed by the Aabutting of the flange and the end of the barrel. For strengthening of the head this sleeve may extend axially and radially outwardly to provide the plate Il as shown in Figs. 1 to8, 10 and 11 by reason of the 9 is a fragmental sectional view illustrat curved portion I3 closely following the arcuate portion I8' between the flange I3 and head II.

In some cases the sleeve I may extend from its other end radially inwardly as at I9 into engagement with a center tube 20 as shown in Figs. '1 and 8, while in other instances, the stock may extend radially inwardly as at 2| for a short distance then axially outwardly as at 22 parallel to the barrel and tube 20 and then radially inwardly again as at 23 and turn back upon itself as at 24 toA engage the tube 20 as in Figs. 10 and 11.

A further reinforcement consisting of a plate I 25 will engage the plate portion I1, span the opening of the head and opening 26 of the reinforcement I'I and engage the center tube 20 by being turned inwardly as at 21 to extend into engagement with raised abutments 28 spaced about the tube and sheared from the stock thereof as shown in Fig. 2, While the outer end portion 29 of the center tube is rolled out- 'wardly over the curvature 30 of this reinforcing plate to assist in binding the plate in position. In Figs. 7 and 8 the portion 21 engages the outwardly extending flange 35 from the portion I9.

In Figs. 1 to 'I the diameter of this reinforcing plate 25 is substantially the same as the diameter of the reinforcement I1, while in Figs. 8 and 9 this reinforcement plate 25 is of a greater diameter than the reinforcement plate I1 and is offset inwardly as at 3| (ses Fig. 8) over the plate I'I so as to contact the head II and extend beneath the rolled edge I4 thereof. In Fig. 9 in which there is no plate I1, the plate 25' is substantially in a single plane without this oiset and likewise extends beneath the rolled edge Il, while in Fig. 11 the outer plate is omitted.

Two particular types of welding are illustrated for securing the parts in assembled relation above referred to. In one instance a continuous resistance seam weld, designated 32, may be provided as illustrated in Figs. 1 to 4 to secure the parts at the joints I6 together. In Figs. 5 and 6 a spot weld is utilized for this purpose, each of the spots of which is designated 33 and is spaced at various locations along the seam I6 for securing the parts together.- Bothof these types of welds, or either one, may occur in the various modifications which I have shown in which the flange I3 of the head II is secured to the end of the barrel in abutting relation, while the sleeve I5 is secured to the flange I3 and also to the end portion of the barrel III. Thus, this weld in this location secures three parts in the fixed relation which they assume. The weld while being at the seam and bridging the same also is by reason of its width located on either side of the seam and in some cases, as in Fig. 12, the spots 31 are even spaced from the seam I6 on either side thereof in staggered relation or these welds on either side of the seam might be continuous.

In the situations where the plate I1 abuts the outer surface of the head II, a spot weld 34, or in some instances a continuous seam weld, is provided to secure these two parts in assembled relation at various locations about the head while a similar spot or continuous seam weld which may be provided at the same time where the reinforcement '25 also occurs, serves to secure this reinforcement to the reinforcement I I as appears in Figs. 1, 4, 5, 7, and 10 and directly to the head as shown in Figs. 9 and 11.

By reason of the arrangement which I have provided the bridging of the seam I6 either by the continuous weld 32 or by spot weld 33 prevents ne wire which may be wound on the spool from entering this seam, while at the same time the Weld secures the three parts in assembled relation and while a curved portion of the head at the arc I8' provides no location at which the wire may enter, even though stresses may occur in the head; in Fig. 12 the abutting of the ends Will be held suiliciently tight by the welds on either side to prevent entrance of the wire into the seam. 'I'he welding of the reinforcements I1 and to the outer surface of the head strengthens the head and by preventing any possibility of sliding one part on the other provides a head which is substantially as strong as though the head were all of one piece of the three thicknesses of the metal.
