This? invention relates to! a wire container` and`V package in which the wire is Wounddn. a' coilin` such relation to the container that the'wireI can bepayed outfrom the inside of.V the coil.
This `amnlication'is a: division o. my application Serial l1\lo.5'79,654', iiled'February- 24,1945.,- now Patent No. 2,457,094 of December 21,1948; .which claims the methooll of: packaging` Wire disclosedherein.-
An object'ofthe invention is to provide an improved package or container for wire. In. placek Iofr the conventional spool this Vinvention employs a-can or` similar package and, in so doing,.obtainsbetter` production for the wire Witha-container that is lighter than thecustomary:A spool.
An objectofthe invention is .toprov-ide an improved Wire package-:formed by.' constructing a.
container around-a coilof Wire While the wirere-V mains on the supportingmeans on which thecoil was Wound. The supporting means are'removed afterv the. container has vbeen constructed'.
In accordance with one feature of the invention-l the. Wire .is Wound. around amandrel .andbetvveenz annular discs thatare hackedv upY and reinforced by 'anges on the mandrel during thewinding operation. After the coilhas been-Woundto-a-pre.
determineddiameter it is coveredfby a cylindricall shell that is connected to the annular discs so as to form a canthatf comprises the containeror.
package kortheA coil oi Wire.
Other features'reiate to the lining'of the container and 'to theformand'correlation of. theend.
discs-and connecting shell for obtaining strong and'tightroll'ed-over seams thatsecure the` endf discs to the cylindrical shell.
Spools have end flanges held together. by. adrum onI which the Wire is Wound and'v theseV liangesflnust'be rigid and heavy enough to support the wire rmly and'to prevent bending of' their outer rim portions.4 With this invention the-discs that take the place of' the end flanges need .notl
be'made of such heavy material because theyare braced by the' mandrel flanges againstbendin'gl dl'iri'ngyth'e Windingoi' the coil and in the corn-- pleted. package their outer edges are connected? together andsupported by a cylindrical 'coverth'at' formsv the body' or side of` the canor container.

The end discs I3 and I4 desirably are of light gauge sheet metal and of somewhat larger diameter than the anges I I and I2` The thickness of the sheet metal parts is exaggerated in the drawing for clearer illustration. The flanges II and I2 back up the end discs I3 and I4 and prevent these discs from bending during the winding of the coil.
Between the end discs I3 and I4 a coil of Wire I5 is Wound about the mandrel I0 until the diameter of the coil I6 reaches a predetermined value. This diameter will be somewhat less than the diameter of the end discs I3 and I4 because the outer edges of these end discs are not held against bending by the flanges II and I2. It is necessary to have the end discs I3 and I4 extend somewhat beyond the outer edges of the flanges II and I2 in order to permit attachment of the rims of the end discs to a cylindrical shell I 'I that forms the side of the nal package.
It is advantageous to have the opening through the inside of the coil I6 slightly larger than the openings through the end discs I3Y and I4 so that the turns of the coil I6 are held against displacement Vacross the entire end faces of the coil. In order to increase the diameter of the opening through the coil I6 a wrapping I8 is placed around the mandrel I0 between the end discs I3 and I4 prior to winding the coil of wire IB, this wrapping serving as a lining for the coil of wire. This wrapping is preferably made of paper or other soft material that serves as padding for preventing the wire from coming in contact with the surface of the mandrel I0. This wrapping I8 may be wound as a helix from strips of paper, or other material, having pointed ends that are cut to the necessary angle for winding around the mandrel I0 without leaving any of the surface of the mandrel exposed. When the wrapping I8 is Wound as a helix it is preferably provided with a pulling tab I9 at the beginning of the helix which is accessible from the hollow center of the coil after the mandrel has been removed. When the package is ready for use the wrapping IB can be conveniently removed by gripping this tab and pulling. The inner end of the wire is preferably connected with the end of the helical wrapping remote from the tab I9 so that it will be drawn out with the Wrapping I8. y
Instead of winding the wrapping I8 around the mandrel as a helix this wrapping may be a paper tube split longitudinally in such a manner that the tube can be collapsed and extracted from the center of the coil in the nal package. This constructionv is illustrated in Figure 10, the split tube being designated 38. As illustrated, the inside diameter of the split tube 38 is equal to the diameter of the central openings through the end discs I3, I4. When using a collapsible tube the lead end 20 of the Wire is preferably fastened to the tube so that it will be drawn out with the tube when the tube is collapsed and Withdrawn.
The wrapping I 8 may also be made up of a sheet of paper, or other suitable material, having a width equal to the length of the mandrel that is to be covered. This sheet is Wrapped around the mandrel a number of times to obtain the desired thickness of padding. In this case the leadend of the Wire is fastened to the lead end of the sheet in such a manner that it is interleaved between the successive layers of paper as the sheet is wrapped around the mandrel. This construction causes the lead end Of the wire to come out of the center of the coil with the paper when the latter is twisted out of the coil.
In the preferred construction, padding or lining material is provided between the ends of the wire coil and the end discs I3 and I4, and also between the outside of the coil and cylindrical shell I'I. The lining for the ends of the container comprises annular discs 2l and 22 which may be made of paper and placed against the end discs I3 and I4 before the coil is wound on the mandrel. The openings through the centers of the discs 2l and 22 are substantially equal to the diameter of the mandrel I0, and these discs are held apart and against the end discs I3 and I4 by the wrapping I8 applied before the coil is wound.
After the coil is completed, its outside may be covered with a wrapping of sheet material 23, for example corrugated paper, that serves as a lining for the side wall of the container and fills up the space left by the difference in the diameters of the coil I3 and of the end discs I3 and I4.
If the wire package is to be used for paying out Wire in series with other similarly packaged coils of wire the outer end of the wire I6, upon completion of the winding operation, is led in to a location that is accessible through the opening at the inside of the coil. As shown in Figure 2, the end disc I3 is shown provided with a radial corrugation 25 which provides a clearance at the end of the coil I6 through which the outer end of the Wire can be inserted. An opening is provided in the mandrel in such a manner that the outer end portion 26 of the Wire, when pushed inwardly through passageway or recess 25 to bring its end to the center of the opening at the inside of the coil, may be in a position such as shown in dotted lines in Figure 1.
With the inner and outer ends 20 and 2B of the coiled wire both accessible from the opening through the coil the inner end 20 can be spliced to the outer end of a similarly packaged coil, and the outer end 26 can be spliced to the beginning of another similarly packaged coil of Wire so that any number of coils can be payed out successively without stopping to make connections. This is useful when laying communication lines quickly from a moving vehicle. The end portion 26 is located behind the disc 2| in Figures 1 and 2, but this disc 2| does not interfere with the wire because the disc 2| is knocked down by the end portion 26 as soon as the remainder of the coil I6 is Withdrawn from the container.
It is a feature of the invention that the outer shell I'I is connected to the end discs I3 and I4 while the coil remains on the mandrel I0 with the end discs I3 and I4 backed up by the flanges II and I2. In the construction illustrated in Figures 1 to 3 the end discs I3 and I4 are provided with flanged rims that extend in opposite directions away from the coil, and the shell II is somewhat longer than the length of the coil plus the lengths of the flanged rims of the end discs so that the opposite ends 'II of the shell I'I can be spun or turned over to a U-shaped contour that embraces the flanged rims of the end discs in the manner illustrated in Figure 3.
In order to prevent possible scratching of the wire, and particularly the insulation thereof when the container is constructed around a coil of insulated Wire, the center openings through the end discs I3 and I4 desirably are provided acometer 5i wit-inlips; on' beads` 23. t.

The end disc 4| has a anged portion 41, the outside diameter of which is a shade less than the inside diameter of the reduced diameter end of the preformed shell 43. This correlation makes it possible to slide the shell 43 over the rim portion 41 and to move the shell 43 longitudinally over the coil I6 until the outturned. end 4d of the cylindrical shell 43 comes in con-i tact with the rim 42 of the end disc 4U.
The disc 4G is connected to the shell 43 by spinning or turning the rim portion d2 over the outturned end 44 as indicated in dotted lines in Figure 7 and, if desired, by then turning the seam against the side of the can as shown at the left-hand end of Figure 9'. The cylindrical shell 43 is connected to the end disc 4I by spinning or bending the inturned end 45 of the shell 43 around the inwardly extending end of the flanged rim 4l. The seam may then be bent further, into the relation shown at the righthand end of Figure 9. This results in double seaming which when used with the proper seaming compound provides water-tight, air-tight seams.
Other methods of constructing the package include the use of a wrap-around shell of the proper length to t between the end discs and with turned beads or rims at the endsof the shell. In that case the outer edges of the end discs will be spun or turned around the beads or rims on the shell for connection therewith. Various other methods of constructing cans around the coil while it is wound around a mandrel and held between the flanges Il and IZ can be employed. The body or shell of the can may be provided with handles, or supports, such as a ring or rings 50 joined to the shell 43 by a bracket 5| that preferably is welded to the shell.
One construction for the mandrel l is shown in Figures '7 and 8. This form of mandrel includes a socket section 53 into which telescopes the end of a plug section 54. The reduced diameter end of the plug section 54 is slightly shorter than the socket in the section 53 so that the shoulder 56 at the end of the reduced diameter portion abuts against the end of thev socket section 53 and there is no groove between the outside surface of the sections 53 and 54.`
To hold the sections of the mandrel assembled a ball latch l may be provided in the plug portion 54 to engage a recess or opening 58 in the side wall of the socket into which the end of the mandrel section 54 extends. In another form the ball latch is replaced with a pin and the socket has an L-shaped slot in its inner wall to receive the pin and lock the assembled members together by a partial turn of the plug in the socket.
The outside surface of the mandrel section 53 desirably is provided with angularly spaced grooves 6D and a leaf or wire spring 6l is lo- [cated in each of these grooves 60. The springs '6l extend for substantially the full lengths of the grooves 6U and each spring may be held in place by a screw 63 located near one end of the spring. The purpose of these springs 6I is to prevent the'wrapping I8 from fitting around the mandrel so tightly that the mandrel is dilcult to remove after the wire has been wound and the package container constructed around the coil.
When a package made according to this invention contains wire that has very little stiffness the structure shown in Figure 10 can be used to 8. insure against snarling of the wire as it is payed out from the container. A cone 65 fits into the opening at the center of the coil I6 and is preferably of such length as to extend substantially halfway through the wire opening in the eyelet 3|. When using such a cone the eyelet 3l must be large enough to provide around all sides of the cone a clearance somewhat larger than the diameter of the wire within the package.
The cone 65 may be connected with a cap that fits over the lip 28 in the same way as the cap 29. This construction will be used with cans that are moved from place to place for supplying wire. If the can or package is used on a bench, or at some other fixed location, the cone 65 preferably is connected to the bench or other location by a bracket 61 which provides a support on which the can is placed when wire is to be withdrawn.
Although the invention has been described as ,fused with wire, it will be understood that it can be used with twisted wires'or other multi-conductor wire or cable in which two or more wires are laid together. Changes and modications can be made in the illustrated embodiments and some features of the invention can be used without others without departing from the invention as deined in the claims.
