3 Claims. v (Cl. 242-78) This invention relates to reeling devices, and,

more particularly, to reeling devices adapted for association with hot rod mills and the like.

In the metallurgical industry, in the manu- 5 facture of attenuated metal stock, and, especially,

rods and other elongated cylindricalobjects, it

is'customary to introduce billets of metal, which have been heated to the proper temperature, to

rollin-g mills for the purpose of elongating them and reducing the diameters thereof. In the case of rod mills, when a billet is reduced through a series of stands of rolls, the rod, as it emerges from the last pair of rollsI 'is of considerable length and travels at conslderable speed, x-and it is necessary to provide some reelingmean's to coli the same.

To this end, driven reels are positioned some distance from the last pair of rolls in the rolltrain invline with the axis of the passes thereof to which the biliet is introduced. Such reels are 'customarily synchronized in speed with the last pair of rolls so as to exert upon the hot stock no pulling tension, except as is hereinafter stated. Such reels usually `comprise a revoluble Abase member upon which two sets of pins, or coiiforming members, are positioned in circular formations concentrically about the axis of rotation of such base member. A platform is provided on top of the base member through which the concentric sets of pins project. The incoming rod is laid between the two sets of pins and rests in coil formation upon the platform. The base member is rotated through la hollow shaft, and carried with it the pins, which, in turn, rotate vision is made for dlscharging it from the reel.

To this' end, the platform is connected to a shaft, which projects through the hollow shaft by which the base member is rotated. This inner shaft 40 is connected to any suitable actuting means whereby the. platform may be moved upwardly away from the base member after the reeling operation is completed and the reel is at rest. The movement of the platform is such as to bodily lift the coil of rod tola plane substantially above the uppermost extremitiesv of the coilforming pins, whereby it may be transferred to any suitable conveyor mechanism.

In operation, these conventional types of reels present certain objectionable features, which result in a considerable loss in material, time, and labor. The principal of these objections lie's in the fact that after the end of the rod leaves the last pair of rolls in remalning between the reel and the last pair of rolls must be wound by the rotation of the reel, which tends to exert a pulling tension thereupon in the absence of the forwarding assistance furnished by the rolling mili. These free ends of the hot rods, usually amounting to '15 feet or the platform. After a coil has been wound, prom the vrolling-train, the stock more, are caused by the pull of the reel to become tightly' wound about the upper extremities of the inner circle of pins thereof. Since the circle defined by the upper limits of the pins is usually of less dlameter than that defined by their base portions to facilitate strippingthe coil, the rod that is .wound about the top portions thereof is coiled to a dlameter smaller than the convolutions comprising the main body of the coil. When such a coil is stripped, these terminal portions of the rod, coiled to a smaller diameter, fall to the inside of the coil. and become tangled with the other convolutions thereof, which necessitates that they be removed as scrap.A

It has also been proposed to make a reel on the revoluble base of which coil-forming pins are fixedly mounted to lean out'wardly, so that any wire coiled about the upper extremities of' such pins will form convolutions having a dlameter equal to, or greater than. the mean dlameter of the coil of which it is a part. The extremities of the fixed coil-forming pins, however they may be disposed to form uniform convolutions of wire, collectively occupy an area commensurate with- -'in fact, greater than-that of such convolutions,

and tendtto -bind the latter to the disarrangement and entanglement of the coil. It will be appreciated that the incoming rod cannot be controlled so as to engage the very extremities of the canted pins, and. hence, must first -encounter thema suitable dlstance below such extremities. At this point, the pins coliectively deflne a smaller area than that defined by'their extremities. The coil ,is thus wound to a lesser dlameter than that of Y"the area defined by the pins' extremities collectively. Itl is obvious that, since the larger must pass through the smaller in discharging a bundle, disruption of the coil will result.

i The reel of the present invention has been de- `signed to overcome the obiectionable features set forth above, and has for its primary object, the provision of a reel'whereon perfectly uniform ooils of rod may be formed, and wherein the terminal convolutions of said rod are constrained to conform in size and shape to the convolutions comprising the body of the coil.

It is another object hereof to provide a reel which will form uniform coils of rod throughout, and which will permit of readily discharging the coil without sacrificing any portions of the latter, and without' disfiguring any portions thereof. L I

Other objects and advantages will be apparent from the following description, with reference to the accompanying drawing in which:

Figure 1 is a partial p an and partial plansectional view of a reel ma i in accordance with the present invention; the section having been taken along line I-I in Flgure 2.

Figure 2 is a mid-sectional elevational view of thedevice illustrated'in Figure 1;

Referring more specifically to' the drawing in which like reference characters refer to like parts throughout, the numeral designates a revoluble base member, which is secured upon a hollow shaft 2, for rotation thereby. Carried in suitable apertures adjacent the periphery of the base member is a plurality of pins 3, mounted equidistantly in circular formation concentrically about the axis of rotation thereof. Disposed inwardly of this circle of pins, also' in circular formation about the axis of rotation, is disposed a plurality of apertures 4 extending through the base member, and adjacent which are positioned pivot-bearings 5 integral with the latter.

A plurality of arms 6 are positioned within the apertures 4 between the pivot-bearings 5, and are secured for oscillation therein about hinge-pins 1. The portions 8 of the arms 6 falling within the apertures 4 are provided with oblique bearing faces 9, which engage complementary faces upon the innermost walls of the apertures in the base member I, so as to cant the outer extremities of the arms outwardly toward the pins 3.

Disposed on top of the base member 3 is a platform IO in which are provided v aperturesll and |2'for the accommodation of the pins 3 and the arms 6, respectively. Disposed co-axially within the' hollow shaft 2, and extending through the base member I, is a secondshaft |3, which is secured to the platform III so as to raise the same for purposes to be described herei'nafter. The

' in'nermost portions of 'the apertures |2 within the platform are sloped to conform to the canteddisposition of the arms 6, and are provided'with inserts Il of bearing metal, which are normally adapted to engage the latter.

In operation, the lead end of a rod is introduced to the reel, which is then driven through the hollow drive shaft 2 at a high speed rate,

corresponding to that at which the rod is being' delivered by the last pair of rolls. The rod is directed to the rotating reel through a usual guide IG, which is disposed to "pour" the incoming rod within the annular space between the pins 3 and the arms 6, so as to form a coil IS upon' the platform IO. At the conclusion of thecoiling operation, the rotation of the reel is stopped, and the shaft |3 is actuated through 'any suitable mechanism (not shown) to-raise the platform supporting the coil IG to a position, such as is shown in dotted lines, Figure 2. As the platform is lifted upwardly, the apertures |2 cause the arms 6 to retract inwardly away from their normal cantedposition, toward each other. 'The coil is freed as the arms are caused to assume a position also shown in dotted lines, Figure 2. The. coil may then be removed from the elevated platform, which thereafter may again be lowered, and the operation repeated.

It will be seen from the above that the normal disposition of the arms 6, when the platform Ill is in lowered position adjacent the base member I, is such as to coil the rods uniformly throughout their length, including the terminal portionsthereof last to emerge from the rolling mill. By the outwardly-canted disposition of the arms 6, the terminal portions of the rod are woundin convolutions having a diameter substantially equal to the mean diameter of. the coil, and by their own weight are caused to drop down into a satisfactory position upon the latter, All ofthe stock, therefore, that has hitherto been rendered unusable, is preserved and handled so as to req'uire that none of it be scrapped. Furthmore, the inward recession of the arms 6, during the discharging operation, provides that the coil be cleanly released, precluding disfigurement of the stock, and insuring against binding, tangling, and other complications, in stripping.

The apertures l in the base member I, within which the arms 6 are adapted to oscillate, are intentionally made of considerable size so that any dirt or other foreign matter, which may collect upon the base member I during the operation of the reel, can be cleaned-out to insure free movement of the arms 6 at all times. The bearing plates ll in the platform apertures |2 are made replaceable, wher'eby the proper positioning and supporting of the arms 6 may at all times be maintained, and wear compensated for. It is also desirable that the hinge-pins 1, and their bearingls in the members 5 and-arms 6, be made of wear resistant material; such as, of bronze bushing material. The latter also avoids any possible corrosive-action setting in after the reel is fiushed with water. In this manner, a free pivotal actionl vcept insofar as is necessitated by the prior art,

and by the recitation of the following claims when interpreted in view thereof.
