Definitions

  • a drum for the winding and storage of cable or wire comprising a core and a pair of flanges flanking the ends of the core.
  • the marginal portion of each flange is surrounded by a resilient, nondeformable ring of metal or synthetic plastic which intercepts impact and shock forces applied to the edges of the flanges, thereby protecting the drum from damage.
  • the present invention relates to cable drums, particularly those which are used for the winding and storage of cable, wire and the like.
  • Conventional cable drums are usually made from wood, metal or light weight alloys. Because the drums are subjected to heavy loading when cable or wire is wound on them, they must be designed to be structurally stable when loaded. They must also be constructed so that they will not roll during transportation. The drums must be able to pass through clearances ranging from to 60 centimeters and the flanges must be able to withstand frequent and repeated contact with hard solid surfaces. The flanges of wooden drums are frequently unable to endure the impact forces to which they are subjected and split, crack or break as a result, thereby making the drum unsuitable for further use.
  • Another object of this invention is to provide an improved cable drum which has flanges that are resistant to deformation and fracture when subjected to impact or shock forces.
  • the improved cable drum comprises a core and a pair of flanges which flank the ends thereof.
  • Each of the flanges includes a central portion and a marginal portion which surrounds the respective central portion.
  • the marginal portions consist of a material which is more elastic than the material of the central portions.
  • the core of the drum is of substantially cylindrical outline and the marginal portions are resilient rings surrounding the central portions.
  • the material of the core and the central portions is a relatively hard synthetic plastic material, while the rings consist of a relatively soft and resilient synthetic plastic material such as polyethylene.
  • FIG. 1 is a plan view of a cable drum, partly shown in section, wherein one configuration of resilient rings surrounding the flanges are shown;
  • FIG. 2 is a side view of the cable drum of FIG. 1, with the internal structure shown partially in section;
  • FIG. 3 is an enlarged view of a portion of the elastic ring as seen along line A-A in FIG. 1;
  • FIGS. 4 through 16 are cross-sectional views of various forms of the resilient rings which surround the flanges.
  • FIG. 17 is a modification of the resilient rings utilizing a metallic band and springs.
  • FIGS. I and 2 there is shown a reel-shaped cable drum comprising a cylindrical core 1 and disc-shaped flanges 2 and 3, all of which are made from a relatively hard and nondeformable plastic.
  • Flanges 2 and 3 which can be of any polygonal outline, are preferably of circular outline and are constructed in double-walled fashion as shown in FIG. 1 as described in extensive detail in US. Pat. No. 3,289,972 issued to Erich I-ITa'fner. This double-walled construction protects the drum from damage which might occur as a result of thrust loads directed to the external sides of flanges 2 and 3.
  • annular supports 5, 6 and 7 are connected to core 1 as well as outer flange 8.
  • Flange 8 is also provided with annular supports 5a, 6a and 70 whose surfaces mate with the corresponding surfaces of the inner flange supports 5, 6 and 7 respectively.
  • the matching support surfaces of flanges 4 and 8 are adhesively joined to each other by any conventional adhesive means. In this way the flanges are made stable enough to withstand the large side loads which result from the successive layers of rolled-up cable or wire.
  • rings 9 which are preferably of circumferentially complete construction and surround each of the flanges as shown in FIG. 2.
  • Ring 9 can be made from a relatively soft and resilient synthetic plastic such as polyethylene. It can also be constructed in the form of a metallic ring mounted on shock absorbing means such as springs provided between the ring 9 and the central portion of the flange.
  • the cross-sectional profile of ring 9 can be in the form of any of a multiplicity of shapes and designs which will be explained in more detail below.
  • FIG. 1 illustrates the central portions of flanges 2 and 3 shown in FIG. 1 surrounded by ring 9, which in this embodiment is made from polyethylene.
  • FIG. 3 illustrates the cross-sectional profile of ring 9 as taken along line A-A in FIG. 1. Rings 9, which are inserted in annular grooves cut in the surface of the outermost support 7 of the central portion of flanges 2 and 3, extend outwardly beyond the central portions to act as shock absorbers or bumpers.
  • FIGS. 4 through 8 illustrate various configurations of the elastic rings which can be inserted in the annular grooves of the central portions of the drum flanges.
  • FIG. 4 depicts a hollow ring 13 inserted in a sloped annular groove.
  • FIG. 5 shows a ring 12 secured to a flange portion 11 and held in place by a second ring 10. Ring 12 is not inserted in an annular groove, rather it is mounted on a first side of the angled corner portion of flange 11 in such a way that it contacts lip 11b. 7
  • Ring [0 which is fastened to the second side of the corner of flange 11 by conventional fastener means indicated by the dotted lines, holds ring 12 in place thereby preventing it from being displaced by axial movement.
  • FIGS. 6 and 7 illustrate other forms of elastic rings 14 and I5 respectively, inserted into grooves cut into the surface of the drum flanges.
  • FIG. 8 shows an elastic ring 16 which includes a metallic insert 17 which serves to prevent damage to the peripheral surface of ring 16.
  • FIGS. 10, 11 and 9 the marginal portion of the flanges has been made in the form of a closed inner ring having projections extending outwardly therefrom.
  • FIG. depicts a ring 19 with hollow projections 22 extending therefrom, in which the hollowed portions are somewhat triangular in shape.
  • FIG. 11 shows a ring with hollow projections 23, the hollow portions being of circular shape.
  • FIG. 9 illustrates a ring 18 having solid projections 21, the ends of which are rounded.
  • the marginal portion of the flange is in the form of a ring 24 having hollow projections which extend inwardly from ring 24.
  • the configurations of the elastic rings shown in FIGS. 13, 14 and 15 are each constructed in the form of a band whose width exceeds its thickness and which has recesses provided in the interior portion of the band.
  • the recesses are in the form of a trapezoid when the band is in an unstressed condition; in FIG. 14 the recesses are rectangular-shaped; and in FIG. 15 the recesses are of circular shape.
  • FIG. 16 Another possible form of the elastic ring is illustrated in FIG. 16 where the ring is of an undulating or wave-shaped outline.
  • FIG. 17 Still another configuration of the elastic ring is depicted by FIG. 17 where the marginal portion of the flange includes a resilient metallic ring 29 mounted on radially acting springs 30 which are interposed between ring 29 and flange 33.
  • a guide pin 31 is affixed to ring 29 and is slidably received in and guided by recess 32 in flange 33.
  • the principle of operation of the resilient cable drum remains the same.
  • the resilient rings forming the marginal portion of the drum flanges intercept, absorb and distribute any forces applied to the edges of the flanges, thus protecting the remaining central portion of the flange from damage.
  • the use of the resilient rings to protect the flanges allows the core and the central portion of the flange to be made from a synthetic plastic such as polystyrene without the risk of cracking or splitting occurring in the core of central portion of the flange.
  • a synthetic plastic such as polystyrene
  • using synthetic plastic for the core and central flange portion reduces the deadweight of the cable drum without sacrificing the required stability.
  • the resilient polyethylene rings permit the cable drum to be loaded and stored for extensive periods of time without the rings being deformed as a result of the cable load. When the load is removed from the drum the rings will reassume their original shape and will still retain their resilient character.
  • a particular advantage of the present invention is that the resilient rings can be replaced whenever necessary, thus greatly extending the period of time in which the cable drums can be reused as well as reducing the cost of replacement of damaged or worn drums.
  • Cable reel comprising a cylindrical core; disc-shaped flanges mounted on said core and defining with said core a space for cable, said core and flanges consisting of a hard resin; and an elastic ring mounted on the periphery of each of said flanges, said ring consisting of a softer resin than said hard resin and being profiled both axially and radially so that each ring has ribs and cavities, thereby increasing its flexibility and ability to absorb shocks without damage to itself, the flanges or the core.
  • each of said elastic rings has an internal surface and each of said flanges has an external surface adjacent to the corresponding ring, one of said surfaces having at least one annular groove receiving at least a portion of the other surface.
  • At least one of said elastic rings includes a circumferentially complete outer part and projections extending inwardly therefrom,
