COIL HOLDER WITH ADJUSTABLE SIDE MEMBERS Filed Dec. 25, 1960 3 Sheets-Sheet 3 INVENTOR. PA UL T/SHKE/V Maw/ a ATTORNEY United States Patent 9 3,022,024 con HOLDER wirn ADJUSTABLE srnn MaMenPs iaui Tishken, 13000 w. Eight Mile Road, Detroit 37, Mich. Filed Dec. 23, 19m, Ser. No. 77,969 4 Claims. or. 242-1101 This invention relates to holders for a coil of stock having a central opening in such coil, and particularly to holders of the type adjustable to accommodate coils of various widths for rotation on the holder as stock is withdrawn from said holder.
An object of the invention is to provide such a holder with a reel revclubly mounted on a shaft and having a plurality of elongated arms, disposed parallel to the shaft and spaced equally, outwardly therefrom to jointly mount a coil of stock at said central opening, and with an inner side member extending rigidly from the inner end of each such arm and transversely to such arm, and with one or more outer adjustable side members respectively, removably carried by respective arms and adjustable in sliding travel longitudinally thereof, toward and away from the inner side member, said outer adjustable side member carrying a cam element normally occupying a position of clamping engagement with the arm to resist travel away from the inner side member, and actuable from said position to afford such travel.
Another object is to revolubly dispose upon the shaft a reel mounting element, and to provide a plurality of elongated rods to respectively mount the respective inner side members upon said element, and to adapt said rods for rotation, and for threaded engagement with a portion of the side members to effect travel of said inner side members and associated arms toward and away from the shaft responsive to rotation of the rods.
Another object is to dispose an end portion of each rod in proximity to the shaft, to mount a bevel gear on said end portion of each rod, and to so dispose said rods relative to said shaft as to afford such engagement of said bevel gears about circumferential surface of the shaft as to effect rotation of all said rods responsive to rotation of one such rod.
These and various other objects are attained by the construction hereinafter described, and illustrated in the accompanying drawings, wherein:
FIG. 1 is a side elevational view of the coil holder withthe arms in their position closest to the shaft.
FIG. 2 is a frontelevational view on-the line 22 of FIG. 1, with said arms moved outwardly from the shaft.
FIG. 3 is a partial vertical sectional view on a larger scale taken on the line 33 of FIG. 2.
FIG. 4 is a partial vertical sectional view onthe line 4-4 of FIG. 3.
FIG. 5 is a partial rear elevational view on line 5--5 'of FIG. 1.
FIG. 6 is a partial horizontal sectional view on line 6-6 of FIG. 1.
FIG. 7 is a partial horizontal sectional view on line 77 of FIG. 2.
In these views, the reference character 1 designates a stand, including a pedestal 2 integrally erected upon a base 3. Said pedestal is appropriately apertured to receive a vertically elongated post 4. A pin 5 maintains the vertical position of the post and averts rotation thereof within said aperture.
A cap 6 is socketed at 7 to surmount the post, being secured against rotation thereon by a set screw 8, or the like. Extending upwardly from the cap, a flange 9 is lapped by a flange 10 projecting from a head 11. A bolt 12 passes through said lapped flanges to afford pivotal movement of the flange 10 and the head 11 relative to the anzaazs Fatented Feb. 20, 1962 flange 9, and a nut 13 may be tightened on said bolt to maintain an established pivotal relationship. The engaged faces of said flanges are preferably formed with serrations 14 extending radially relative to the axis of the bolt to resist undesired pivotal movement when said nut has been tightened on the bolt.
The head receives the inner end portion 15 of a shaft 16, which is secured therein by a screw 17. A reel mounting element 18, in the form of a spider, is revolubly carried by the shaft with an anti-friction device 19 disposed on the shaft between the head 11 and the hub 21 of said spider, while the spider is revoluble on antifrictien device 29. The reel mounting element could function as well if it were annular or quadrangular in outline, but, obviously, a considerable saving in material and weight is derived from use of the spider.
Outwardly of the spider, a gear housing 22 encloses the central portion of the shaft 16. Said gear housing is secured in position by screws 23 extending through flanges on said housing to thread into bosses 24 formed on the hub of said spider. Said gear housing is revoluble on anti-friction device 25.
To resist development of momentum, and consequent excessive speed of rotation as stock is withdrawn from the coil, a drag plate, or annular brake 26 is secured against rotation on the shaft as by a key 28. The outer end portion 29 of the shaft is threaded to receive a nut 3%. A spring 31 reacts between the outer face of the hub 26a of the drag plate and a collar 32 to apply rotation resisting force to said drag plate. It is preferred to interpose a disc 27 of fiber or other suitable material between the opposing faces of the gear housing 22 and the drag plate 26 to prevent wear of said faces.
A lubricant is admissable to the interior of the gear housing by means of grease fitting 33, opening into a passage 34 extending inwardly through the shaft 16 and opening into said interior. At its-outer end the gear housing is recessed to receive a grease seal 35, while a grease seal is associated with the aforementioned antifriction device 29 in the hub 21 of the spider.
A reel to carry a coil of stock is formed of a plurality of coil supporting arms 36 elongated parallel to the shaft 16, and spaced equally, outwardly therefrom to be received in the central opening of a coil of stock. A pair of reinforcing ribs 37 extend longitudinally of each arm and are spanned by a transversely disposed web 38 at the inner end portion of the arm.
An inner side member 39 of the reel is formed integrally with each said arm. Such inner side member is elongated transversely of the arm, and takes an arcuate form in cross-section to provide arcuate ribs 40. Two bosses 41, 42, spaced longitudinally of the inner side member, project rigidly inwardly therefrom to slidably abut the outer face of a leg of the spider 18. A stop block 43 is secured by screws 44 on such inner face, at the outer end of said leg. Said bosses 41, 42 and the block 43, are each formed with a hole, so that such holes in the assembled construction are in line to rotatively mount an elongated adjusting rod 45. Said rod has a threaded portion 46 which has threaded engagement with the hole in the boss 42.
The gear housing is formed with a plurality of holes radially bored therein to admit the inner end portions 47 of the adjusting rods 45. Terminally, each rod carries a bevel gear 48 secured by a pin 49. In the construction illustrated, four rods are employed, positioned radially to the shaft 16 at an angle of degrees from each other. The four bevel gears intermesh about the circumferential surface of the central portion of said shaft. Said rods turn in anti-friction devices 51 received in bushings 50, and each rod is formed with a shoulder thrusting inwardly against anti-friction device 52.
. (3 The outer end portion of one or more rods is adapted in any conventional manner to receiver a'crank or the 'like (not shown), as by formation of flats on said end portion, to afiord rotative actuation of said rod. Due
to the threaded engagement of the rod in the boss 42,
such rotation effects radial travel of the inner side member 39 and associated arm 36 toward or away from the shaft 16, depending, of course, on direction of rotation of the rod. Through the gear train established by said intermeshed bevel gears 48, rotation of one such rod eifec'ts rotation of the other three. As is now clear, such arrangement affords uniform, concurrent radial positioning of the inner side members 39, and consequently of firearms 36, with which said side members are integral. This afiords adjustment of said arms to. adapt them to mount stock coils having central openings of various diametcrs'. Each stop block 43 serves to maintain the radial position of the corresponding'rod and to limit travel of the corresponding inner side member away from the shaft. From the foregoing, it will be apparent that to prevent V dislodgement of a coil of stock from said arms, it is necessary that outer side members he provided for one or more coil mounting arms of the reel. To allow a coil of stock to .be mounted upon said arms, such side members must be removable from said arms; and to afford accommodation of the reel to varying widths of coiled stock, said outer side members must be adjustable longi-v tudinally of the arms.
It follows, finally, that means must be provided to maintain such side members in a desired position longitudinally of the arms against outward thrust of a stock coil. 7
These problems are resolved by the construction now to be described. An'oute'r, adjustable side member 53 is formed with a slot 54 to slidably receive an arm 36. The lateral marginal portions 55 of the arm are parallel, and the side faces 56 of the slot are formed with grooves 57 which slidably interengage with the marginal portions of the arm. The outer side member is thus removably mountable on an arm 36 for sliding travel longitudinally of the arm. 'In the illustrated construction, only three such side members are shown, though another may be mounted on the. fourth arm if desirable.
convolutions of a stock-coil to become dislodged outwardly of the reel, a projection 67 is formed on the outer side member to adjoin or abut the side of such stock coil. One may, if desired, form a hole 68 in the end of such projection, whereby the side members may be hung out of the way while a coil of stock is being loaded on the arms.
It should be noted that in the described construction, any outward thrust exerted by a coil of stock will serve to intensify the force with which the cam159 clamps upon the arm 36 to resist said'outward thrust. Testing of the construction shows that no tolerances are required which might allow wabbling of the, outer adjustable side member on the arm. Further, the construction is such that an excessively worn cam is replaced with comparative ease, and such wear does not require replacement of or remachining of the outer side member, or the arm.
What I claim is: e
l. A holder for coiled stock comprising a shaft, a support for the shaft engaging. an end portion of the shaft, a reel-mounting. element 'rotative on and substantially radial to the shaft, a stock-receiving reel having radially elongated angularly spaced inner side'members and having arms substantiaily parallel to said. shaft and respectively rigidly carried by the inner ends of the respective inner side members and similarly spaced from said mounting element, and having a plurality of radially I elongated outer side members, said outer members being A groove 58 in the outer adjustable side member is I formed transversely to the slot and has an intersection with said slot. Disposed within the groove is an arcuate 03111559,: rotatably actuable upon a pivot pin 60. A handle 61 projects from the cam to afford manual rotative actuation to release the earn from a clamping position of en- 'gagem'ent with a fiat surface 62 of thearm at the intersection of the slot 54 and the transverse groove 58. Such engagement resists said longitudinal travel of the outer adjustable side member on the arm, once the former is established in a desired position. 7 r
A spring 63 reacts between the outer side member and said handle,- to urgethe cam into said releasable engagement. A stud 64 on the side member, and 65 on the handle, prevent escape of the spring, and a stop pin 66 extends across the groove 56 to limit response of the handle to the spring when the outer side member is removed from an arm. To resist any tendency of the slidable at their inner ends on and along said arms to selectively vary the spacing of the inner and outer side members, means for locking the outer side members in selective sliding'positionsthereof upon said arms, a plurality of radially elongated rods for varying the diameter of the reel, each of such. rods respectively extending between the reel-mounting elementand the respective inner side members, a pair of radially spaced lugs rigidly' carried by each inner side member, the reel being mounted by said lu'gs on the rods, one of each pair of said lugs' forming a bearing for the corresponding rod and the other being threaded and engaged by a'threaded portion of such rod, means compellingrotation of all said rods responsive to a rotation applied to one thereof, the reel being expa'n'sible and contractibleby travel on" said rods.
2. A holder for coiled stock as set forth in claim 1, said reel-mounting element being a spider having angularly spaced legs respectively spaced lengthwise of the shaft from therespective inner side members of the reel.
3. In a holder'for c'oiled stock as set forth in claim 1, means on said reel-mountingelement limiting expansion of the reel H p a I 4. A holder for coiled'stock as set forth in claim 1, said threaded lugs having 'sliding engagementwith said reel-mounting element.
