ATIWEVE'Y' Patented Aug. 3, 1943 Alwyn BortomSouth Orange, N J., assignor to- AssociatedPatentees, Inc., Ampere, N. J., a corporation off New Jersey Application November 29, 1941, SerialNo. 420,962 5 Claims. (01. 242414) The invention hereindisclosed relatesto stock reels and the objects of the invention primarily are to provide a reel constructiononwhich the roll of stock may be readily engaged'and quickly and easily centered and to "accomplish this in a simple, compact, sturdy design of relatively few parts and low cost. Other desirable objects and the manner of attainment will appear as the specification proceeds.

The drawing accompanying and forming part of the specification illustrates certain practical commercial embodiments of the invention. The structure however may be modified and changed in various ways all Within the true intent and broad scope of the invention as hereinatter-defined and claimed. l

Fig; 1 is a broken part sectional View of a stock reel embodying features of the invention.

Fig. 2 is a broken and partsec'tional frontpview of the reel. 7 r i Fig. 3 is a fragmentary and part sectional detail View of, a power driven embodiment of the invention. i a

As shown in Fig; l, thereel consists in the main of a series of stock supporting arms 1, projecting ir-omplates or brackets 8, slidably guided at 3; over the radially projecting spoke elements it, of the hub H.

Hub l l is shown journaled on a stud or spindle l2, carried by the support it, on the upper end of the stand :4, and controlled as to freedom of rotation by the brake bushing I5, sli-dingly keyed hand nut ll.

taking up the end thrust occasionedby the brake."

Radial adjustment or the con; supporting arms is efiected in 'the'illustration by a c-a'mdisc or such points as will 1o cate' :the coil supportsall at the same radial distance from-the center, even though the rolls necessarily areengaged with cam surfaces of unequal distances from the center. At'present'it is preferred topintherolls on the backs- 0f the pl-ates in thedifferent rel-atively rath'al positions necessary to locate the plates at equal distances from the center, but it is contemplated that the rolls may have adjustable mountingsgas in radially slotted portions on the backsof the-plates, thus to enable complete interchangepf the coil supports with the adjustments necessary to properly locate the individual cam rolls,

Fig. llshows how the SCYOHCSJIII can be a relatively thin disc of a necessary thickness only sufficientto carry the cam groove, thus to take up but small space'at the inner'end of thehub. This view also shows how the thrust bearing i8 may be sunk in" the outer face of the scroll disc. i r

It desired, facings of brake-lining material or thelike, may1 be provided between the opposite ends of the hub and the brake element at the frontand the scroll cam at the back.

The brake element l5;is keyed at 23; orotherwise non-rotatably confined on the stud, so as to brake the rotation of the reel to-a desired extent andthe cam plate, fric'tionally engaged as it is by the end of the reel hub and-backed up by'the thrust bearing I 8, is in effect frictionally coupled to the" reel hub. The' itch of the scroll cam may be so low that the coil supporting arms will hold of themselvesin the positionsto whichthey have been adjusted, In any event however, the reel may be faced in the direction, whether for unwinding'or Winding on purposes, such that with any slippage at the friction clutch or coupling at 2 resulting from the fdrag of the cam disc on the reel, such movement will be'in the right direction to expand and tighten the arms in the coil of supported stock.

A holdingfpinris indicated at 25, Fig. 1, mounted in the spindle supporting bracket, adapted to .beadvanced into one of the seats 23,"fin the back of the scroll cam for holding the latter,

when desired, for armadjusting or other purposes. This pin may have asorew mounting as indicated at 21, or otherwise be set in the slips port, so that while normally retracted, it may be readilygadvanced into holding engagement with the camplate. This. holding: pin isdesir: able for securing the scroll pl-ate'and the reel fricticnally coupled thereto over extended periods as when placing or removing a heavy coil of stock in respect to the supporting arms and for holdirig'thecam while the reel body is turned one way orthe other for expanding or contracting of the radially projecting coil confining flanges 28, of the arm carriers 8.

To facilitate the placing of the coils on and the removal of coils from the supporting arms,

the outer coil confining and retaining members 29, are preferably removably mounted as by equipping them with springpressed hand levers 3B, pivoted at 3!, and having the eccentric or cam-shaped end. faces 32, engageable with the flattened outer sides 33, of the arms both to releasably lock the retainers in place and to hold them against rotation on the arms. The locking on the hand levers 30, are faced so as to slide freely inwardly over the coil supporting arms but to interlock and resist outward movement, the springs assisting in this holding action but yielding easily to spring pressure applied for releasing the holding engagement.

What isclaimed is:

l. A reel of the character disclosed, Comprising in combination, a supporting spindle, a reel hub and ascroll cam rotatably'mounted on said spindie in relatively rotatable relation and coil carryarms connected with and radially adjustable eccentric portions are faced to bind and secure H The reelis of especially simple and compact design and is readily assembled by simply slipping the scroll plate and the hub over the spindle, then engaging the arm carriers over the spokes and backing the hub up against the scroll plate to enter the rolls, in their proper positions in the cam groove, after which it isonly necessary to mount and tension the brake element,

which thereupon becomes a retainer for the whole structure, inaddition to its functions as a brake and as a means for maintaining the frictional coupling between the reel hub and cam plate.

The invention is applicable to either free or motor driven reels. An example of the latter type is illustrated inFig. 3 and which differs from the form previously described, particularly in that a drive pulley 0r equivalent drive means 36, is fixed to and carried by the inner end of the hub; I l and the scroll cam i9, is rotatablymounted on the hub instead of directly on the spindle, between the innerface of the drive element 36,

and a flange 31, on the hub. This mounting enables relative rotation of hub and scroll cam, such as necessary to effect expansion and contractive movements of the reel arms. A clamp screw is indicated at 38, for securing the cam plate in fixed relation on the reel when that may be desired, as afteian adjustment of the end of the hub, against the opposing face of the stud supporting bracket M.

The motor for operating the power driven form of reel may be mounted directly on the reel stand asindicated at 42, and be connected with the reeloperating element 35, as by belt drive indicated at 43, as in the-A. E. Borton Patent the radial spokes and coil carrying arms and.
