, I have invented a coiling reel which success
fully overcomes the aforementioned objections,
and in addition; is characterized by further novel
and useful features. In accordance with my in
30 vention, I position a pair of hubs in spaced rela
tion on a supporting and driving shaft. I mount
discs on the hubs in driving relation therewith.
A protective sleeve extends from one disc to the
other and is tightly secured to both. Blades ex
35 tend axially between the discs and are secured
with thermal insulating material il.
. Blades I9 extend between the discs i4 and I5.
The blades have end portions 20 disposed at >right
angles to their length. lThe body portions are
hollow and have openings 2l on the inner sides a0

pendently of the others. For a complete under

formed into hooks 23 at one side, holes or eyes 24
being formed in the other s_ide.

jections 25 provided with spaced holes 26 and 2B’.
'I‘he blades I9 are secured to the projections 25
by pins 21 and 28 as shown in Figure 1. 'I'he

The pins 21 are permanently secured Íon the
`discs as by welding at 29. In applying a blade
to the reel, the hooks 23 are first engaged over the
protruding ends of the pins 21. The blade is
then swung about the pins 21 until the holes 24
are in alignment with the holes 26’. ‘I'he pins 28 w
are‘then inserted and lock the blade in ñxed
position relative to the discs. 'I'he pins 28 are
through the pins 28 and projections on the end
portions 20.
When the blades have all been secured to the
discs, the resulting reel is driven so that sharp
edges 2_2 of the blades are leading. If a length
er het strip is then directed substantially radially
of the reel, it will enter between two adjacent
blades and be bent partially around the second
of the two, thus hooking the leading end of the
strip secured to the reel for coiling.
It will be clear that the mounting of the blades
on the discs permits the former to expand freely
and to diil'erent extents at diil'erent points on
the peripheries of the discs. Thus, if the reel
remains stationary while the ñring of the furnace
continues, the lower blades may expand more
than the upper blades without introducing'any
stress whatever into any part of the reel. The
blades have a limited free movement axially of
the reel since the hooks 28 slide on the pins 21
ilxed to the discs, and the pins 28 secured to the
20 end portions 20 of the blades can slide in their
holes 28’ in the discs. In case of breakage, fur
thermore, a blade can easily be replaced without
disturbing the remaining parts of the reel. This
is a-marked advantage over the permanently
25 welded construction of the reel previously men
tioned. To remove a blade, it is necessary only
to knock out the cross pins 30, remove the pins
28, and lift the hooks 28 oil the pins 28.
Since the protective sleeve il surrounding the
between the discs is tightly welded to the
latter, the insulation I8 is permanently enclosed
in the space between the shaft and the sleeve.
'I'he various parts of the reel will preferably be
made of heat resistant alloy since it must operate
35 at elevated temperatures, such as 2000*’ F., when
used in the furnace of a hot mill such as that of
the Steckel patent.
According to a modification of the structure
just described, a shaft 35 is provided with toothed
portions 38 and discs 88 having central bores
of hot strip on the reel composed of the shaft.
discs and blades.
By securing the pins 42 firmly to the projec
tions 40, I avoid the possibility of the pins becom
ing loose in the holes 4I due to the shock and
stress normally experienced in the operation of a
coiling reel.
The shaft 3B is provided with an enclosing
sleeve I 1 nlled with thermal insulating material
I8 as in the structure of Fig. 1. When it is de
sired to remove one of the blades 44, it is only
necessary to knock the locking ring 48 of! the
split ring 41, and after removing the latter, to
shift the blade longitudinally oi! the pins 42.
Although I have illustrated and described but
two preferred forms of the invention, it will be
understood that changes in the construction il
lustrated and described may be made without de
parting from the spirit of the invention or the
scope of the appended claims.
I claim:
l. A coiling reel comprising a pair of spaced
discs disposed coaxially, a plurality of blades ex
tending between said discs, said blades having
end portions at right angles to their length, said 25
end portions each having an eye and a hook
formed therein, the hooks adapted to engage pins
permanently secured to the discs and the eyes
adapted to receive removable pins passing through
the discs.
2. A reel for coiling material comprising a pair
of spaced, coaxial discs with blades extending
therebetween, hooks on said blades adapted to
engage projections on said discs, and removable
means securing the blades and discs together to 35
prevent disengagement of said hooks.
3. A reel for coiling material comprising a pair
of spaced, coaxial discs with blades extending
therebetween cooperating hooks and projections
on said blades and discs, and removable means 40
slotted to receive the teeth 88 are disposed on the
shaft. ' The teeth have shoulders 31 against
for preventing disengagement of the hooks and
jections have spaced holes at 4i therethrough.
tions, hooks on said portions removably engaging
projections on said discs, and connecting pins
extending through said portions and discs
4. A reel for coiling material comprising a
which the discs 88 abut. The discs are held in
abutment by rings 38 welded to the shaft. The shaft, a pair of discs mounted thereon in spaced
. relation, and a plurality of blades extending be 45
45 discs 88 have projections 40 thereon, as in the tween said discs having angularly disposed por
structure of Figures l through 3, and these pro
Pins 42 are inserted in the holes 4I and are se
cured in position by welding, as shown at 48. <
Blades 44 similar in general to those shown at
I8 have lugs 45 extending from points adjacent
the ends thereof. 'I‘he lugs 45 are bored at 48
whereby the blades can be mounted on the discs
by alining the holes 46 with the pins 42 and mov
55 ing the blade axially so that the pins enter the
holes. The blades are secured in position by a
split ring 41 which seats in an annular groove 48
adjacent the end of the pins 42 on the right
hand disc 38. The halves of the ring 41 are held
60 in place by a holding ring 49 welded thereto. The
blades have bosses 50 thereon adapted to engage
the edges of the projections 40 for the reason al
ready explained, viz., to relieve the pins of the
collapsing load imposed by the winding of a coil
whereby the former can expand or contract inde
pendently of the latter.
5. A reel for coiling material comprising a pair
of spaced, coaxial discs with blades extending
therebetween, axial pins disposed peripherally
oi' said discs, hook means on said blades engage
able with said pins, and removable means for
holding said means in engagement with said pins.
6. A reel for coiling material comprising a pair
of spaced coaxial discs, a blade extending there
between, pins extending axially through the discs,
hooks on the blade engaging said pins, and re
movable pins traversing said blade and discs for
securing said hooks in engagement with said first
mentioned pins.
