The fastener 16 comprises a hardened steel ratchet 50 to hold the parts together in locked assembly and a dished
yieldable ?ange on each barrel portion bearing upon a
plate 20 having ‘a dished ?ange 22, a central rod receiv
is drawn integral from the medial portion of the ?ange 22.
The arms 24 in this preferred embodiment are prefer
ably formed by punching a series of substantially circular
openings 30 about the central opening 18. The ends 32
are shaped to approximately conform to the shape of the
rod, and by reason of the inclination of the arms, the
lower edge 34 of the ends 30 is the portion which ?rst 60
engages the surface of the rod.
As shown in FIG. 5, the fastener 16, when assembled
on the rod 18, has the under surface 36 of the dished
?ange 22 bearing against the outer face 38 of the side
?anges 12 and due to its dished con?guration exerts a 65
constant pressure thereon.
Referring to FIG, 6, there is illustrated the position of
able arms to hold the side ?anges tightly against said
spool in a constant take up pressure to automatically
overcome shrinkage and loosening in the reel assembly.
