5 Claims. l

This invention relates generally to the metal reel art and is particularly concerned with a reel having new end construction including provision for the application of a braking or driving belt thereto.

Sheet metal reels, as constructed heretofore, have possessed several disadvantages. The ends or heads were not sufiiciently strong and rigid even when welded or riveted constructonswere used, especially when the reel was heavily loaded, and no satisfactory way was known forembodying in sheet metal reels means to control the rate of rotation of the reel when it was being unloaded.

By means of the present invention I have overcome these disadvantages. I have made sheet metal reels which are quite substantial` particularly as regards the strength and rigidity of the ends, by makingreel ends from sheet metal parts which are connected by double seams at their outer peripheries and mutually brace each other. This construction makes it possible to incorporate in the peripheries of the ends belt grooves for use in controlling the rate of rotation of the reel.

In the drawings which accompany and form a part of this specification and which show various forms of the invention,

Figure 1 is an end view of one form of reel embodying the present invention.

Figure 2 is a fragmentary, central, sectional view taken on line 2 2 of Fig. 1.

Figure 3 is a fragmentary end view of a modified form of the present invention. l

Figure 4 is a fragmentary, central, sectional view taken on line d--li of Fig. 3 corresponding to Fig. 2.

Figures 5 and 6 are, respectively, fragmentary end and top plan views of means for securing lagging in place on the reel of Figs. 3 and 4, Fig. 5 being taken on line 5--5 of Fig. 6.

Figure '7 is a fragmentary, sectional view showing one form of construction of the outer edges of the ends of a sheet metal reel.

Figure 8 is a view similar to Fig. 'I but showing a modified form of construction.

Figure 9 is a fragmentary, end elevational view of a modified form of the present invention.

Figure 10 is a sectional View taken on line illiii of Fig. 9; and

Figure 11 is an enlarged, fragmentary, sectional view of a rim structure slightly different from Y that shown in Figs. 9 and 10.

The reel shown in Figs. 1 and 2 comprises an elongated, cylindrical sheet metal hub i having inturned flanges 2 at each end and shoulders 3 near each end. 'Ihe ends or heads of the reel of 55 Figs. 1 and 2 are alike and, accordingly, a description of one will sufilce for both. Each end or head includes a ring 4 having out-turned flanges 5 and 6 at its inner and outer edges, respectively. The inner flange rests on the outside of hub i and abuts against shoulder 3 and is preferably welded to hub I. Each end or head also includes a disk 'i of sheet metal which has an opening 8 at its center and one or more openings 9 which open into the interior of the hub. The disk "i rests on in'turned flanges 2 of hub i and are preferably welded thereto. Disk i is inclined toward ring t, as is indicated at i0, and at its outer edge has a double seam connection li with flange 6 of ring 4. The openings 8 in the ends of the reel are to receive an axle on which the reel may rotate duringloading and unloading and openings 9 may be used to engage pins on a head which is employed to rotate or drive the reel during loading.

The reel of Figs. 3 and 4 is quite like that of Figs. 1 and 2, and like numerals indicating like parts in these several figures. The end disks 'ia are quite like disks i of Figs. 1 and 2 but differ therefrom in certain respects. The flanges defining openings 8 and 9 are reinforced by rings i2 which are disposed on the inner side of each disk 1a, surround the disks of these openings and are welded to the disk. The outer portions lila of disks la are deformed at a plurality of places, as indicated at i3, to bear against ring t and thereby add to the strength and rigidity of the head end. A double seam Il joins the outer periphery of disk 1a to the outer flanges 6 of ring d.

Lagging is shown in Figs. 3 and 4. A plurality of metal sheets i5 are provided with channel shaped edges I6 to seat on the ends of the 'reel and cover the material which is wound on the hub. As is better shown in Figs. 5 and 6, the adjacent ends of sheets l5 are bent back to form hooks l1 over which a clip I8 is fitted to retain the ends in position. One end of each clip i8 is bent over and bears on the outer side of the reel head and are attached, preferably by welding I9, to a partly cut away portion 20 of disk 1a. Each clip i8 has a hole 2i near one end thereof and parallel scoring 22 extending from said opening to a corresponding hole at the other end. The partially cut away portion 20 and scoring 22 facilitate removal of the lagging.

In Fig. '7 is illustrated a modified form of construction of the outer periphery of the reel or heads. In this case the ring 4 has a flange 6a which extends axially, then outwardly as at 6b, and then is folded back into Vshape as is shown .posed of ring 32 and disk 33. ilange 34 which projects inwardly between the end of the hub 3i and disk 33. Ring 32 extends v at Se. Disk 1' is shaped to conform to portions Qa; 6b and 6c of the flange of ring i' and has a 'portion 1b which extends inwardly radially and flange 1c which rests on the outer side of ange 6a of ring 4'. These engaging parts of ring 4' and disk 'l' form a V-shaped groove 25 for receiving a driving or braking belt to control rotation of the reel during unloading, and also during loading, if desired.

Fig. 8 shows a grooved end or head construction somewhat like that shown in Fig.- 7. In this instance, however, the outer flange 6' of ring 4" is bent to form one side on the bottom of a groove 28, the other side thereof being formed by the double seam connection I6 of flange 6' of ring 4 and ange il of disk 1".

It will be understood that the end disks of Figs. 1 and 2 may be reinforced as is shown in Figs. 3 and 4 and may be provided with lagging and lagging securing means as shown in those two figures. It will also be understood that the ends or heads of the reels ofFigs. 1 to 4 may be provided with grooves as shown in Fig. 7 or 8 or obvious variations thereof.

In Figs. 9 and 10 the illustrated reel comprises a sheet metal drum 3i and an end or head com- Ring 32 has a along the outer surface of hub 3i as is indicated at 35 and then extends outwardly at right angles to the drum as at 36. Disk 33 is spaced axially from ring 32 except for engagement with flange 34 and for the circumferentially spaced engagements indicated at 31 where the disk is depressed sufficiently to contact with the ring. The outer peripheries of ring 32 and disk 33 are double seamed together to form a rim 38 having a belt receiving recess 39. As is indicated by dotted lines 40 of Fig. 9 a stiffener 4l is fastened to the inner surface of disk 33 about openings 42 and 43 which extend thru the disk.

Figure ll shows a double seam construction slightly different from that shown in Figure 10. The ring 32 and the disk 33' are bent the same as in Fig. but the folds of metal at the periphery are not flattened down onto one another as in Fig. l0 but, on the contrary, are separated to provide space 45.

Reel ends or heads embodying the present invention are exceptionally strong and rigid as will be seen from examination of the forms illustrated in the drawings. The disk and ring comprising a reel head are connected to each other at their outer peripheries and tc the hub at their inner peripheries. The outer connections are double seams, that is, the edge portions of the disk and ring are folded or rolled upon themselves to form an interlocked joint which is strong and which is lighter and less expensive than welded or riveted connections. The disk and ring are inclined to each other and thereby cooperate to resist side thrusts and may constitute an even more rigid structure when the disk is deformed to engage the ring at spaced places at at I3in Figs. 3 and 4. Moreover, these advantages may be realized in reels having belt grooves around the heads and having lagging to protect the article wound upon the hub. Thus the present invention satisfies long felt needs in reels and provides eicent, light and inexpensive ap paratus.

Having thus described my invention so that others skilled in the art may be able to understand and practice the same, I state that what 4 I desire to secure by Letters Patent is dened in what is claimed.
