Referring now in detail to the drawings, the Coiling reels for applications of the character side walls oi' a furnace of any suitable type are mentioned have been made heretofore by dis indicated at l0. The furnace may be such as posing a pair of discs on a shaft andwelding that shown in the Steckel patent above menthereto blades extending parallel to the shaft. tioned. A shaft extends through the side walls Certain diñlculties were encountered in the use i0 and is journaled in suitable bearings outside of such reels. In the first place, it is‘sometimes of the furnace (not shown). The shaft is pref necessary to stop the reel for a considerable erably arranged to be driven, for example, in the period and in such event, the blades on diiferent - manner shown in the patent referred to. Hubs I2 and I3 are disposed on the shaft Il in spaced portions thereof are heated to different temper atures since the furnaces are fired from below. relation and are keyed thereto. Discs I4 and it The resulting unequal expansion of the blades are mounted on the hubs I2 and i3. The discs has introduced internal stress and has actually and hubs have interiltting projections such as caused joints between the blades and the discs teeth and slots I6 and I 8' whereby toprovide to- be fractured. Another objection was that driving connections therebetween. A tubular it was diil‘lcult to prevent the insulating material sleeve i1 'surrounds the shaft Il and extends be disposed around the shaft from sifting out at the tween the discs Il and l5, being securedto the joint between the discs and a protective sleeve hub portions I4' and I6' thereof.` 'I‘he spacerbe surrounding the shaft. i tween the shaft ii and the sleeve I1 isfwelded , 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. l0 15 20 v25 . . 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 thereof. A One edge of the blades is relatively pendently of the others. For a complete under 0 standing of the invention, reference is made to the accompanying drawings illustrating a pres ent preferred embodiment. sharp as shown at 22, while the other edge is rounded. The end portions 20 of the blades are formed into hooks 23 at one side, holes or eyes 24 being formed in the other s_ide. 85 The discs Il and l5 have a plurality of pro 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 end portions of the blades lie on the outer sides 40 of the discs. Each blade has bosses 25' engaging the edges of the discs to take the collapsing load ` of the coil winding oiI the pins. to the outerv sides thereof by connections per mitting free expansion and contraction of the blades and the removal of any one blade inde Inthe drawings: Figure 1 is a longitudinal sectional view 45 through a coiling reel in accordance with the invention; Figure 2 is a transverse sectional view along the line II-II of Figure 1; line I--I of Figure 2 so indicates the plane on which the section of Fig ure 1 is taken; Figure 3 is a transverse sectional view through l ' secured in position by cross pins I8 extending x one of the blades; Figure 4 isa view similar to Fig. 1 showing 55 modified form of the invention; n ` 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. Il 2 l y 2,116,191 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 shaft between the discs is tightly welded to the 30 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 40 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: f’ 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 30 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 projections. 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. < 50 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.
