' s4 claims.

This invention relates to improvements in winding reels and its purpose is to provide an improved reel of simplied construction which may be used with advantage for winding strip steel and the like in spiral coils.

It is common practice in the rolling of strip steel in steel mills to wind the strip material in spiral coils as it comes from the mill stands and tor this purpose power driven winding reels are in general use. To permit the coil of strip material to be held rmly during the winding operation, and to allow the completed coil to be removed readily at the conclusion of the winding operation, it is necessary to be able to expand and contract the core of the reel. This has been accomplished in commercial practice, according to one plan commonly employed, by the use of a reel having a core made up of a plurality of outer segments capable of radial expansion under the inuence of rollers interposed between the segments and an inner rotatable actuating( member provided with inclined cam surfaces adapted to cause radial movement of the core segments, through the intervening rollers, upon relative rotative movement of the segments and the actuating member. In order to retard one ci the relatively rotatable units, brake mechanism has commonly been employed 4and the power for eiecting rotation of the reel during the winding operation has been applied to the inner actu- In that apparatus, very high pressures per unit of area are set up between the rollers and the core segments `and between the rollers and the inclined wedging surfaces of the actuating member, thereby causing the' rupture of the lubricating oil films, the rapid wear of the contacting surfaces, and the frequent sticking of the rollers, thus rendering the operation of the apparatus unreliable. These difficulties have been increased by reason of the fact that the driving power has been applied to the inner member, giving rise to a tendency to wedge and lock the rollers during the normal rotation so that they could not be readily released when desired; and the necessity for mounting the segments for free radial movement under/the influence of the segments has resulted in a tendency of the rollers to tilt endwise, instead of maintaining their of a true cylinder.

is to overcome the foregoing diiiiculties, and others, by providing an improved simplified .winding reel in which the power for effecting rotation is applied directly to the segments upon -which the strip material is wound and in which 194.1, serial No. 395.967

the expansion and contraction of the segments is eiected in a positive and simple manner. A further object is to provide a winding reel having a plurality of expansible and contractible segments which are moved radially without the use of any brake mechanism and without the use of rollers. Another object is to provide a winding reel having radially movable segments adapted to be actuated by a tapered expanding member which has only an annular line contact with the segments in all positions except one, which may correspond to the expanded condition of the core, so that the resistance to movement of the expanding member is comparatively limited. Another object of the invention is to provide a winding reel having a plurality of segments to which the rotative power is directly applied at points adjacent to the region where the coil is wound, thus eliminating any tendency for the segments to tilt or twist during the winding operation. Still another object of the invention is to provide a winding reel having a plurality of core segments which are always anchored securely at one end and which are driven by power Aapplied directly thereto. Still another object of the invention is to provide an expansible and contractible winding reel core wherein the radial movement of the core segments is effected by a power actuated member directly engaging the segments with a pressure which is independent of the driving force applied to the reel and independent of the inertia of the coil wound thereon. A further object of the invention is to provide a winding reel having radially movable segments in combination with actuating means having relative movement with respect to the segments, and provided with means for preventing the access of dust and the like to the relatively movable parts by which the expansion and contraction ofthe segments is effected. A further object of the invention is to provide a winding reel having a minimumfnumber of parts which may be readily manufactured and` assembled. Other objects relate to various features of construction and arrangement which will appear moe fully hereinafter.

The nature of the invention will be understood from the following speciiication taken with the accompanying drawings in which two embodiments are illustrated. In the drawings,

Fig'. 8 shows a vertical section taken on the ,line 8 8 of Fig. 7; and

Fig. 9 shows a vertical line 9-9 of Fig. 7.

In the form of the invention shown in Figs. 1 to 6, inclusive, the'winding reel comprises a core I made up of `a plurality of complementary segments I0, each having an arcuate surface I0b which is adapted to cooperate with the similar surfaces of the other segments to form a substantially continuous cylindrical surface upon which a coil of strip steel I I, or the like, is adapted to be wound. The portions of the segments uponV which the winding surfaces I0b are formed pro-` ject beyond the open end of a housing I2 within which portions of the segments and parts of the driving mechanism are mounted. The outer projecting portions of the segments are provided on their inner sides with arcuate inclined surfaces |0 which converge inwardly toward the housing I2 and which are adapted to coact with an expanding member I3, constructed in the form of a truncated cone, mounted upon the end of an actuating rod IH adapted to be moved in either longitudinal direction by. fluid pressure mechanism. The rod I4 is provided with a tapered end portion I4*at which is adapted to fit a correspondingly tapered axial bore formed in the expanding member I 3 and the extremity of the rod I4 is threaded for engagement by a nut I by which the expanding member is held in position on the rod. The surfaces II'Ic may bevconvexed inwardly between their ends or their longitudinal elements may be straight to facilitate manufacture. In either case, it is apparent that there will be only one position of the expanding member I3 where it will contact from end to end with the surfaces II) and that in all other positions there will be only an annular line contact. The surfaces may be so formed that the complete contact between the segments and the expanding member will occur in the expanded condition of the core, when it is carrying the greatest load, while in other positions the annular line contact will limit the section ltaken on the .friction so that the expanding member may be more readily moved. By arranging for an an nular line contact in the fully expanded condition of the core, the resistance to starting the movement of the expanding member when theI core is loaded will, of course, be materially reduced. To eiect a further reduction of the resistance to movement of the expanding member, its outer tapered surface I3 is recessed annularly as shown at I 3b, and this also insures a better contact between the end portions of the expanding member and the segments. To insure a good contact of the tapered portion MB of the actuating rod and the expanding member, the internal bore of the expanding member is enlarged between its ends as shown at I3".

In order to prevent the access of dust and the like to the contacting surfaces of the segments I 0"l and the expanding member I3; the inner surfaces of the segments I0 are provided with grooves I0d which align with each other circumferentially and which receive the marginal edges of a disk I6, formed of leather, rubber or the like, which is adapted'to adjust itself to the radial movements of the core segments and to maintain a closure across vthe outer end of the expanding member I3. For the same reason, the longitudinal die faces IIJe ofthe segments are provided wit-h grooves I0f which are inclined longitudinally to correspond with the taper of the surfaces I0". These grooves I0t register with each other in the opposite faces |0e of adjacent segments and they are occupied by the edges vof flexible connecting members I1, formed -of leather, rubberor the like, which are coextensive with the surfaces |0 and which are adapted to prevent the entrance of dust or the like in a radial direction to the contacting surfaces I0c and |35.

The segments I0a of the core I0 are provided with elongated arms or extensions I0i which project into the housing I2 and which terminate in arcuate extremities I0h mounted to oscillate upon the spherical surface of Va bearing member I0 .which has a central bore |86 slidably` and rotatably engaged by the rod I4. When the seg-I ments I0a expand and contract, as hereinafter described, the arcuate portions l0h are adapted to oscillate upon the bearing member I8. These portions ||Ih are maintained in contact with the bearing member 8 by a driving bracket or cage 20 which, lfor purpose of assembly, may be formed in two laterally separable parts molded together. The cage 20 acts as a driving frame through which the power for effecting rotation is applied directly to the segments |05 of the core, andv it is provided with an annular arcuate surface 2li'l adapted to contact with the outer curved faces of the portions 0h of the segments, as shown in Fig. 1, so that the parts I0h may oscillate within the surface 20a when the outer ends of the segments' are moved radially. Adjacent the annular surface 20B, the driving frame 20 is provided with an annular flange 20b which is located in a concentric position with respect to a-ilange I2b formed on the housing l2. A roller bearing unit 2|, having its rollers mounted in inclined positions, to receive thrusts toward the right, as viewed in Fig. l, is mounted between the anges 20b and |2b, thus providing a bearing for the inner end of the'frame 20.

In order to provide a driving connection between the parts which have just been referred to, a series of radial pins 22 are mounted in registering apertures formed in the part 20c of the frame upon which the surface 20a is formed, through the parts I0h of the segments I0, and extending into the bearing member I8, as illustrated in Figs. 1 and 6. The apertures I0i inthe parts |011, which are engaged by these pins, are elongated in the direction ofthe axis of the device, to permit the segments to oscillate about the member I8. These pins 2'2 are retained in position by an annular driving gear 23 which fits upon the outer cylindrical surface of the part 2|)c and which is secured to a radially extending flange 20d of the driving frame by means of a series of threaded studsh24. A key 25 engages aligning keyways in the part 20 and in the gear 23 to prevent relative which is secured upon the reel, not only at the innermost end thereof,v

but at a point nearer to the place where the strip material is wound upon the segments of the reel, thereby preventing the tilting and twisting of the segments during the winding operation, the driving frame 20 is extended toward the mouth of the housing i2' and is provided with a radial ange 23 to which there is secured a driving member 28, of annular form, provided with a forwardiy extending flange 28 which is adapted to rotate within and in proximity to the flange I2c of the housing. An annular roller bearing unit 29 is mounted in an annular recess formed in the housing and on the outer side of the ilange 28 to support the driving member 28 and the forward end ofthe driving frame 2B during their rotation. A packing ring 33' is mounted in an annular groove formed in the inner face of the flange I2u to bear against the outer side of the flange 28, thus preventing dust and the like from gaining access to the contacting surfaces of the roller bearing unit 29.

The driving member 28 is secured to the ange 25e of the drivingframe by means of a series of studs 3i and this driving member is provided on its inner annular surface with a series of radially projecting teeth 281 which are adapted to enter notches i formed in' the enlarged intermediate portions of the segments II! of the reel, two of these notches in adjacent segments registering with each other to form, in eiect, a recess between two adjacent teeth so that, as the driving frame 2U is rotated under the influence of the powerv applied to the driving gear 23, the driving member 28 supplies a driving force to the segments illa adjacent tothe forward end of the .housing I2. 'I'he drivingi member 23 is provided 'with a series of radially extending cylindrical apertures 28s and these apertures are normally closed at their outer ends by an annular ring 32 which surrounds the driving member, being shrunk thereon or otherwise secured thereto. Within each of the apertures 23 there vis mounted a coil spring 33 and the function of these springs is to force the segments Ill"l inwardly against the expanding member I3 so that when this expanding member is moved toward the left, as viewed in Fig. l, to the position shown in Fig. 2, these springs cause the segments I3a to move inwardly away from the annular driving member 28, thereby effecting the contraction of the projecting portion of the reel to the extent permitted by the adjustment of the expanding member i3 therein.

lThe movement of the expanding member I3 for the purpose of controlling the expansion and contraction of the reel ill is effected by a piston 35 which is connected to the rod i3 and which is mounted to reciprocate within a cylinder 35. This cylinder has a forward extension 35 provided with an annular flange which seats against the outer face of a circular plate 31, the flange and the plate being secured to the rear end of the housing I2 around the opening in which the roller bearing unit 2i is mounted. The plate 3l has an 'of the rod to hold it in ing mounted in a groove around this opening to bear against the rod and provide a dust tight con- -nection between the rod and the plate. The piston 35 is loosely engaged by the rod I4 so that this rod may rotate within the piston during the normal rotation of the winding reel, a ball bearing unit 40 being mounted on the reduced end of the rod and within an annular recess 35a formed in the piston. A nut 4I engages the threaded end fixed longitudinal position with respect to the ball bearing unit and the piston. The central passage 35b of the piston is loosely engaged by the rod It and the piston has Ia tubular extension 35" surround the rod and slidably engaging an aperture formed in the end wall 36b of the cylinder. A stufng box 42 is mounted in the end wall 3Ib around the tubular extension 35c of the piston to provide a liuid tight connection A between these parts. A metal cap 35d closes the rear end of the piston and extends over the end of the rod IH and the nut 4I. When the piston 35 is in its retracted position, as shown in Fig. l, corresponding to the expanded condition of the reel, a space d4 is provided between the cap 35d. and the head t5 of the cylinder which has an inwardly extendingA ange 45a adapted to limit the rearannular part 31a which fits within this aperture I ward movement of the piston. Compressed air or the like is adapted to be admitted to the space M through a pipew, leading from an air compressor or the like, and another supply pipe B1, for com pressed air or the like, communicates with the space between the other end of the piston 35 and the end wall 36b of the cylinder. By admitting compressed air or other iiuid to the end of the cylinder adjacent the head $5, the piston 35 will be moved toward the right,` as viewed, in Fig. 1. thus expanding the segments of the core so that they are in condition for the winding thereon of the spiral coil II. Upon admitting compressed air or the like through the pipe to the chamber at the rear end of the cylinder 3B, the piston 35 will be moved from the position shown in Fig. 1 to the position shown in Fig. 2, thus moving the expanding member I3 to its forward position and allowing the segments I0 of the reel to be contracted under the influence of the coil springs 33. When the parts are in this condition, the coil Il may readily be withdrawn from the reel. When the piston 35 is in this forward position, as shown in Fig. 2, there is a space 48 between the forward end of the piston and the end wall 36b of the cylinder so that when compressed air is again admitted through the pipe 41, it may have access to the entire face of the forward end of the piston to"` cause its movement in the opposite direction.

The form of the invention shown in Figs. 7, 8 and 9, which is now considered to be the preferred Aform of the invention, comprises a core 50 made up of a plurality of segments 5ila having outer arcuate surfaces which form a composite cylinder upon which the spiral coil 5I of strip steel or the like is adapted to be wound. These segments 5D extend rearwardly into a housing 52, as in the form of the invention previously described, and the expansion of the forward portions of the segments is adapted to be eiected by an expanding member 53 having, in general, the form of a truncated cone and having, also, the function of controlling the contraction of the segments under the inuence of fluid pressure mechanism hereinafter described. The expanding member is provided with an outer annular surface 53a which may be either straight or slightly concaved from spondingly shaped and inclined inner surfaces 50 of the segments 50. As in the form of the invention previously described, the force required to move the expanding member is limited by the fact that the expanding member and the segments have only an annular line contact except in one position of the expanding member, which may preferably-be that position in which the core is fully expanded. The longitudinal movement of the expanding member 53 is adapted to be effected by a reciprocable ro'd which is'adaptedl 4.

to be actuated by uid pressure mechanism similar to that described in connection with the actuation of the rod Il. This rod 5I is provided with a tapered forward portion 5I* which fits within a correspondingly tapered central aperture formed in the expanding member 53 and the expanding member is secured upon this rod by a nut 55 which engagesv the threaded end of the rod. 'Ihe forward portions of the inner surfaces of the segments 50EL may be provided with transverse grooves 50d in which there is seated the outer edge portion of a disk 56 of leather, rubber or the like. which is adapted to prevent the access of dust or the like to the contacting surfaces of the expanding member 53 and the segments 50". Other strips of leather, rubber or the Alike may be mounted between adjacent segments to extend longitudinally,.as in the case of the strips i1, previously described, for the purpose ofpreventing the access of dust to the contacting surfaces of the segments and the expanding member between the radial faces of the segments.

The segments 5i) are provided with rearwardly extending supporting arms 5D'I which project into the housing 52 and which are provided at their rear ends with enlarged portions 5i!h secured in apertures 58 formed in a spider or drum 58. This spider 58 has a hub portion provided with a bore 58b in which the rod 54 is slidably and rotatably mounted and this hub portion 58" of the spider is joumaled in a roller bearing unit 59 secured in the rear end wall 528 of the housing. The portions 50 of the arms 508 which are adjacent .to the spider 58 are resilient so that they permit some flexing of the segments in this region to allow the forward portions of the segments to expand contract, as permitted by the expanding member 53. f/ l With the rear ends of the segments of the core having a fixed-mounting in the rotatable member 58, as described above, it is necessary to apply the driving force to the segments for effecting' their rotation only at an intermediate part of the structure and this is accomplished by a driving gear 60 which is located at the forward end of the housing 52 with its anges 60 and 6i)b journaled in ball bearing units 6| and 62, respectively, which are mounted at the inner margins of the anges 52b and 52e formed on the housing 52. The flange 52 has an extension provided with a groove in which is mounted an annular sealing member 63, of felt or the like, by which the access of dust to the roller bearing unit 62 is prevented. The driving gear 60 is provided on its outer side with teeth 60" which mesh with the teeth of a driving pinion 64 secured upon a driving shaft 65, as shown in Fig. 8, this shaft being adapted to be connected to a driving motor or other source of power by which the reel may be rotated during the winding operation.` The driving gear 60 is provided on its inner side with a series of spaced teeth Bild, 'which enter the notches 5i)J formed in segments 50a, these notches or recesses being located at the marginal edges of the segments with lsgaeaioi the notchesof two segments adapted to receive one of the teeth 50d, and with the notches of sulcient depth to permit radial movement of the segments, -as in the form of construction previous- 1y described. By this arrangement, a positivel driving force is applied to the segments 5I)l during the winding operation and this force is applied at intermediate parts of the segments, thus overcoming any tendency of these segments to tilt or twist longitudinally or laterally while the strip material is 'being wound thereon.

As heretofore mentioned, the rod 54 is adapted to be moved endwise by fluid pressure mechanism similar to that previously described for the purpose of actuating the expanding member 53. When this expanding member is moved toward the right to the position shown by full lines in Fig. 7, the forward ends of the core segments are expanded so that their outer surfaces 5l)b form a composite cylinder upon which the strip material 5| may be wound. lWhen the expanding member 53 is moved toward the left to the position illustrated by dotted lines in Fig. 7, the segments 50* are adapted to be contracted so'that their outer surfaces 50i then taper slightly toward the forward end of the device to facilitate the removal of the spiral coil of material which has been wound thereon. The contraction of the segments when the expanding member 53 is moved to its forward position is effected by fluid pressure mechanism including a series of cylinders 66 which extend radially inward from the outer wall of the housing 52 with their cuter ends secured between the ange 52h and another annular flange 52d. A series of cylindrical pistons 61 are mounted to reciprocate inthese cylinders and they have inner rounded ends 51* which are adapted to contact with the outer faces of the arms 508 of the segments of the core. 'I'he outer ends of these cylinders are provided with a series of ports in which are mounted supply pipes 68' leading from an annular supply pipe 68 located within the housing 52 adjacent to the flange 52d. Compressed air is supplied to the pipe 68 through a comprising a plurality of pipe 69 leading from an air compressor or other source of supply through the wall of the housing, as shown in Fig, 9. When compressed air is admitted to the cylinder by which the rod 54 is actuated, for the purpose of moving the expanding member 53 to the position shown by dotted lines in Fig. 7, compressed air may be simultaneously admitted through the pipe 69 to the various cylinders 56 sothat the pistons 61 will be actuated to move the segments 50V inwardly as the expanding member 53 is moved toward the left, as viewed in Fig. 7.

.Although certain forms of the invention have been shown and described by way of illustration, it will be understood that it may be constructed in various other embodiments coming within the scope of the appended claims.
