Referring to Figs. 1, 2, 3 and 4, the reel 1, comprises flanges 2 and 3 secured to hub 4 in the following manner: Grooves 55 are formed in flanges 3 and 4 into which the edges 66 of hub 4 are pressed, after which the welding electrodes 7 and 8, shown in dotted form are applied, and a spot weld, as 99 obtains, firmly joining the hub and flanges, the weld 9a also joining the ends of the punching from which said hub is formed. Hub 4 is provided with openings 1010 to permit entrance of electrodes, entrance of film clip spring 11, and reduction in weight.

Film clip spring 11, has film guiding portions 12a-12a and clip ends -12--12 normally biased to hold film 13 securely, hole 14 serving to permit introduction of a pencil or other instrument whereby said clips may be forced apart for more ready entrance of the film for anchorage by the clips, said spring is restrained to proper location by button projections 15-15 formed therein and seated in holes 1616 of hub 4.

The spindle sleeve 17 comprises 2 stamped

portions

18 and 19, such having flan e projections 2020 adapted to be spot we ded to flanges 2 and 3 by welds 2121, also female projections 22-22 adapted to join said portions at the center of completed sleeve 17 and also extensions 17a17a, for allocating the sleeve 17 in the flange orifices 17b17b. By this novel construction, it is possible to assemble

portions

18 and 19 to their respective flanges 2 and 3 before assembly of said flanges on hub 4, in this'manner permitting a very rigid attachment of the spindle sleeve 17 to said flanges. comprise pin slot portion 23 formed therein, said slot, however, only extending part way through the hub, in this manner reducing weight, simplifying stamping and permit ting better allocation of joining projections Flanges 2 and 3 of stamped formation comprise a corrugated section 24 adjoining the hub which acts as a resilient mounting for the more outward portions of the flange. lln fact suflicient flexibility is obtained whereby the flanges may be restrained to touch each other, as shown by dotted position of Fig. 7.

Arranged radially in flanges 2 and 3 are the re-enforcing grooves 2525, which also serve as a guide for allocation of film as it is wound onto the reel.

Arranged circumferentially in flanges 2 and 3 are also re-enforcing grooves 2626,

reaaeea advertent contact therewith during high rotative speeds of the reel.

When reels as 1, are made up for film storage purposes, a label pocket as 30 is preferably attached to one of the flanges, as 2. See Figs. 1 and 5. For such occasion a pocket or recess as 31, having a sub-recess 32, is formed in flange 2, and in said sub-recess is secured preferably by welding, a stamped frame member 33, having inturned edge 34, forming the opening through which the label 35 is viewed and a slot 36 through which said label is inserted.

Referring to Figs. 6 and 7, showing a service reel as 40, of substantially light construction for shipment of reels substantially long distances, and comprising flanges 4141 of? similar form, rigidly secured to hub 42. Flanges 4141 have a corrugated section 43, similar to section 24, of flanges 2 and 3, adjacent hub 42, and are also supplied with grooves 44-44, similar to groove5 of flanges 2 and 3, into which the edges 45 of hub 42 are rigidly allocated. Said flanges and hub may be welded together as described in connection with reel 1, or a modified construction, as shown in Figs. 12, 13 and 15, may be employed and wherein perforations as 4646 are arranged in groove 44, through which lock lugs 4747 are inserted, whereafter'said lugs are bent over, as shown in Figs. 12 and 13, securely locking the flanges thereto.

Pin sleeve member 48 may be of the same form and mounted in the same manner as sleeve 17 of reel 1, or it may be modified in In reel 40, the film end may be secured by a spring clip member 11, as shown in reel 1, or a modified form as shown by Figs. 14 and 15, may be employed, and wherein, clips as 51-51 are formed from the hub stamping proper, thereby eliminating the use of a In Fig. 15, the hub 42 is shown as the developed stamping from which said hub is formed.

As the flanges 2 and 3 of reel 1 are without perforation at the section in which the film is wound, it will be apparent that by supplying a band, or cover, as 55, to encircle the outer edges of said flanges, the film will be enclosed in a substantially fire proof casing. The means for securing band 55 in place on reel is shown by Figs. 8 and 9, wherein one end, as 56, is formed into a cylindrical clip, as 57,-over which a similar clip, as 58 on opposite end 59, is restrained to snap, subsequent to which the wire 60 may be inserted in holes 61-61, and a seal, as 62, locked thereon, in this manner preventing band from being removed from reel 40, before seal wire is broken.

Flanges 4142 are relieved by perforations 65-65 for weight reduction, the edges of said perforations being formed into a groove 67-67 to effect rigidity to the result ing spokes and remove, as 66-66, the more or less ragged'metal from possible contact with the film.
