PENT OFFICE REEL Royy W. Brown, Chicago, Ill.

Application February 5, 1941, Serial No. 377,413 1,3 Claims. (Cl. 242-1728) This invention relates to devicesfor uncoiling Wire. More particularly, it relates toa device for uncoiling wire wound in an unsupported reel.

Many devices are known in the. art which are designed to be used for uncoiling wire. Ineluded among these are` devices adapted to, be used in uncoiling unsupported reels, aswell as devices intended to be used with wire wound on a spool or other similar support.

As mightl be expected, it is.v considerably, more expensive to supply wire, in spools than in, unsupported reels. One factor contributing to this greater cost isthe limited quantity of. wire which can be wound on.r al single spool as, a practical matter. On the other hand, due to the difliculties encountered. with the previously known devices foruncoilingwi're from unsupported reels, the wire spools have pro-ven more attractive commercially than the unsupported. reels, particularly to users of relatively ne. wire., despite the increased cost.

The devices` heretofore in use for uncoiling wire from unsupported reels arev not only quite heavy but, in addition, have the disadvantage, particularly in the case off ne wire,l that they tend to be jerky in operation and slap back when the pull is released. Inthe case of staple, wire, for example, it has been found that in the known types. of devices. for. unreeline the Wire. if. the stitch oni the. stapling. machine. is not parteci. the wire will tangle. and. in the Case i large reels will back up aroundthe reel.. The. speed of operation. of theY known reels. is also quite de-n cidedly limited It is therefore an object off this invention to providea device for uncoiling wire from,unsup ported reels, which may be. operated.. at high speed and which has little orv no tendency to tack-slap,v jerk or. tangle the Wire Where the speed of operation is varied, either regularly or irregularly.

A more speciiicobject is to provide a device for uncoiling ne wire from unsupported reels, both large andsrnalL. which may be operated at high speed and in which there itsV little o r no tendency for the wirev to hack-slap, tangleY or jerk where the speedof uncoiling isy variedv for any reason.

Another object is to provide a reel for uncoiling wire which isv light in weight and' relatively simple in construction.

Anotherv object is to provide a device for uncoiling wire in whichV the coil ofV wire remains stationary and is. drawn off through tubular. means revolving about the axis of the coil.

Another object is to provide a device for uncoiling Wire, in which` means is providedV for preventing, the coil from riding up ofi its support when the wireis uncoiled rapidly.

Another object is` to provide a device for uncoiling wire, in which means are provided for preventing back-slapping, jerking and tangling, particularly at high speeds of` operation.`

Another object is to providek a device for uncoiling wire, in which the meansl for guiding the wire away from the coil and the means for preventing the coil from riding up away from its support are centrally removably supported.

Another object is to provide a device for uncoiling wire, in which means are provided for preventing the coil from riding up off its support at high speeds of operation, which means are, however, centrally supported and vertically shiftable for ease in removal and to decrease strains during high speed operation.

Other objects will appear hereinafter.

It4 has been. found that the foregoing objects may be accomplished by a device such as that illustrated in the accompanying drawings which form a part of this specification and in which Figure l is an elevation of a device for uncoiling wire, involvingr features of the present invention;

Figure 2 is a horizontal sectionon the line 2-2 in Figure 1;

Figures 3, 4 and 5 arel views in perspective of three parts of the device shown inFigure 1; and

Figure 6 is a vertical section on the line 6-6 in Figure 2.

The improved reel illustrated in the drawings is mounted on a base I0. The base Ill; as shown, is a relatively thin metal plate bent downwardly on either side, as at I2, and inwardly, as at I4, so as to support the central portion I6 of the plate in, an elevated position, Centrally of the central portion I6 a short, vertically extending rodv I8. ismounted in an opening in the plate I6 and secured in position by a pair of nuts 20 and 22. The nutsZ and 22, as can be seen, are threaded onto the lower end of rod I8, the nut 20 being located above the plate IS and the nut 22 below, so that when they are drawn up tight the rod I8 is rigidly supported.

Extending outwardly in radial planes about rod I8 as an axis is a series of six bent rods 24, the inner and outer ends of whichrods 24 are respectively secured to circularly disposedrods 26 and 28. As may be seen, each rod includes an inner, vertically extending portion spaced outr wardly a short distance from the rod I8. At the upper end of the vertical portion 38 the rod 24 is bent outwardly and downwardly to provide a short section 32 and thence from the end of the section 32 the rod again extends vertically downwardly to provide a section 34. The section 34 terminates a short distance above the lower end of the section 38 and at this point rod 24 bends sharply outwardly and slightly downwardly to provide a section :iiiy and from the section 35 it curves gradually into another section 38 which extends generally vertically but has a slight slope outwardly.

The inner end of each rod 24, that is, the lower end of each section 30, is secured as, for example, by welding, at 4D to the ring 26 at equal distances about its center. The outer ends of the rods 24, that is, the upper ends of the sections 38, are similarly secured, for example, by

welding, as at 42, to the ring 28. This provides a structure shown in Figure 5. This structure in turn is secured to the plate I6 by securing each rod 24 to the plate I6 at approximately the point where sections 36 and 38 merge. The securing means may take the form of a weld, as at 44.

Slidingly mounted on the rod I8 is a hollow tube 46 which extends upwardly a substantial distance above the ring 28. end of the tube 46 a washer 48 is aixed thereto as by welding, for example, and another washer 56 is similarly secured to the tube 46 a short distance above the lower end thereof. Extending between washers 48 and 58 is another set of six bent rods 52. Rods 52 also extend in radial planes about tube 46 and are equally spaced. They include an upper horizontal section 54 exu tending outwardly from the tube to a point located about over the middle of the space between the vertical section 34 and the vertical section 38 of rods 24. From this point they bend sharply inwardly and a downwardly extending section 56 is formed which curves gradually inwardly for most of its lengthy becoming substantially vertical adjacent the lower end which is located a short distance below the lower end of tube 46. The rods 52 then bend sharply upwardly and inwardly to provide a section 58 and then on a level with the under surface of washer 58 they again turn to provide a horizontal section 68, terminating at the tube 46.

The rods 52 are firmly secured in position by welding or otherwise securing their upper and lower ends, respectively, to the washers 48 and 58. Additional strength may be imparted to the structure by extending the weld or other securing means so as to afx the rods 52 to the tube 46 at both ends, as well as to the washers 48 and 58.

To give additional strength to the flaring annular form, designated generally 62, and which includes as parts the tube 45 and the rods 5?., a pair of rings 64, 86 is provided at the top. Ring 68, which is of relatively large diameter, is secured to the rods 52, as by welding or other F Adjacent the upper thereby is tubular guide means 68 for the uncoiled Wire. The guide means 68 includes a rod 'I0 extending vertically in the upper portion of the hollow tube 46. As is shown, the portion of 4 the tube 46 in which rod 'I0 extends is preferably somewhat greater than that in which rod I8 extends due to the greater twisting force exerted on the rod 10. The rod 18, which has about the same diameter as rod I8, is freely received within the tube 46 so that it may be turned therein but is preferably large enough to be held substantially vertically in the tube 46.

The guide means 68 is supported in the desired position vertically by a nut I2 and washer 'I4 welded or otherwise secured thereon. The lower face of the washer, as may be seen, rests against the upper end of tube 46 and turns thereon. Also secured in and forming part of the nut and washer assembly 12, I4 is a dat,

- horizontally extending bar 'I6 which projects outwardly a short distance beyond the ring 86. The bar 16, together with the upper end of the rod 1D, supports a hollow tube 'I8 which is secured to the rod 10 and the bar 16, respectively, at and 82, by welding or other securing means.

The tube 18, as may be seen, includes a short, vertically extending section 84 located radially outwardly a short distance beyond the ring 66. Above the short vertical section 84 the tube I8 curves gradually into an inwardly and upwardly extending section 86 which, at the point where the tube I8 is secured to the rod, curves gradually upwardly into another vertically extending section 88, the axis of which is substantially coincident with the axis of the rod 10.

To load into the device a coil of wire 90 to be uncoiled, the form 62 and the guide means 68 are separated from the supporting bed, designated generally 82, simply by lifting the hollow tube 46 vertically from the rod I8. The coil 98 may then be positioned in the bed 92, as shown in Figures 1 and 6. The form 62 and guide means 68 are then replaced. The free upper end 94 of the coil may thereupon be threaded up through the tube 18, passing first through the section 84. then the section 86, and eventually being brought out at the top of section 88 as shown. As the wire is drawn out the guide means 68 revolve on rod 'I0 as a pivot.

The guide means 68, in addition to serving to vprevent tangling and back-slapping of the wire, also serves to take out a substantial portion of the curl, delivering the wire in the desired condition for whatever use it may be intended. The guide means 68 also cooperates with the bed 92, particularly the portion formed by the outer, vertically extending sections 38 of rods 24, to prevent jerking, back-slapping and tangling. Due to the sections 38, the tendency for the Wire to overrun and continue to uncoil, even after the pull on the end 94 has stopped which results in back-slapping and tangling, is greatly minimized.

The device illustrated has been operated with very ne wire, such as is used for stapling, at speeds as great as 2200 R. P. M. without encountering any undesirable back-slapping, tangling or jerking. The Haring form 62 also assists in making possible high speeds of operation since it tends to prevent the coil 90 from riding up, as will be clear tothose skilled in the art. It is, however, free to give slightly to any such force since it is slidably mounted on the rod I8. The outwardly flaring form of the rods 52 tends, however. to wedge the coil more tightly if it rises aaeascoY vertically a-t all and thusA provides an increasing resistance.

Although the parts maybe constructed of any desirable material, ithas been found thatA sheetiron isl suitable vfor the base Ill, and that soft and somewhat resilient iron rods may be very satisiactorily employed to formv the rods 24 and 52', as well as the rings 26, 28, 64 and 66, the rings 26, 28, 64 and 66`being formed simply by bending a suitable length of the rod material into'a circle and welding' or otherwise securing the ends together. The hollow tube 46 may be formed'with cast-iron pipe, for example TheV tube 68, rod and rod I8 may be formed of any-desired'material. Preferably-y the rod I8 and rod 10 will be slightly larger in diameter and formed of a more rigid material than the rods 24, 52, et cetera.

The advantages of thedevicewill be apparent from the foregoing description. The great and outstanding advantage is, of course, that wire, particularly ne wire, may be uncoiled from unsupported reels at very high speeds or slow speeds, as desired, without undesirable back-slapping, jerking and tangling. The outer, vertically extending portion of the bed 92 materially assists in preventingover-running of the wire with resultant tangling, back-slapping, et cetera. The inner flaring form 62, as has been repeatedly point out above, tends to prevent the coil from riding up out of the bed; thereby retaining it in position where the bed 92 may be effective to prevent tangling and back-slapping. The guide means 68 also cooperate in guiding the wire away from the coil in a uniform manner and in taking out soine of the curl, delivering it centrally where the rate of rotation is lessY manifest.

It is apparent that many widely different embodiments of this invention maybe made without departing from the spirit and scope thereof and therefore it' is not intended to be limited except as indicated in the appended claims.
