Definitions

  • ABSTRACT OF THE DISCLQSURE A method and means of cable spoofing wherein the cross-over area on the cable spooling drum is recessed in order that the first layer of cable section disposed in the cross-over area will be suspended above the bottom of the recessed area. This provides a yieldable area at the cross-over for substantially eliminating or greatly reducing the tremendous crushing pressures on the initial layer of the cable in multi-layer cable spooling operations.
  • the yieldable feature at the crossover substantially reduces the build-up of the cable at the cross-over area for reducing eccentric configuration of the wound cable on the spool.
  • This invention relates to improvements in cable spooling apparatus and more particularly, but not by way of limitation, to an improved cable spooling apparatus and system designed and constructed for substantially eliminating crushing of the cable in a multi-layer cable spooling operation.
  • a spooling system for controlling the winding of the initial layers of the cable which is in widespread use today is known as the Le Bus controlled spooling system and comprises utilization of a drum core having a cable receiving groove provided on the outer periphery thereof.
  • the cable receiving groove comprises a plurality of alternate parallel sections and helical sections, with the most common arrangement being the provision of two helical sections and two parallel sections, although :in some instances only one helical section is provided. Of course, it may also be of advantage in some instances to provide more than two helical sections.
  • the helical sections provided On the drum core are commonly known as the pitch areas and are usually so arranged as to move the cable from one parallel section through a preselected lateral dimension and into the next succeeding parallel section.
  • the cable is disposed in the groove and is efliciently wound around the drum core to provide an efiicient basis for the succeeding or subsequent layers to be wound thereon.
  • the cable is reversed in direction at the drum flange by the usual kicker members, or the like, as is well known, and the cable follows or lies in the groove provided between the wraps of the previous or first layer of cable.
  • the second layer of cable is moving in a reverse direction, and consequently rises upwardly over the helically wound portion of the first layer and continues to wind in the parallel sections toward the op- 3,391,879 Patented July 9, 1968 posite drum flange.
  • These areas on the second and succeeding layers of the wound cable are commonly known as the cross-over areas.
  • the present invention contemplates a novel multi-layer cable spooling system and apparatus particularly designed and constructed for substantially eliminating the crushing and scrubbing of the cable at the cross-over areas.
  • the helical or pitch sections of the drum core are lowered whereby the cable portion disposed in the pitch section will be suspended between the respective ends of the spaced parallel sections.
  • the first layer of cable does not actually engage or contact the surface of the drum core in the pitch areas.
  • Another object of this invention is to provide a cable spooling apparatus wherein the pitch area of the spooling drum is lower or of a smaller diameter than the parallel areas of the drum for reducing cable build up in the crossover areas to substantially preclude any out of balance condition during the cable spooling operation.
  • a further object of this invention is to provide a novel cable spooling apparatus wherein the pitch area is lower or of a smaller diameter than the parallel areas of the drum core whereby movement of the cross-over areas of the outer layers of cable around the periphery of the drum core during a cable spooling operation is substantially eliminated, thus providing a more etficient control of the spooling operation.
  • a still further object of this invention is to provide a novel cable spooling apparatus and system which is simple and efiicient in operation and economical and durable in construction.
  • FIGURE 1 is a cross sectional view of a cable spooling drum embodying the invention.
  • FIGURE 2 is a sectional view taken on line 22 of FIGURE 1.

  • reference character 10 generally indicates a cable spooling drum comprising the usual oppositely disposed drum flanges 12 and 14 having a drum core 16 interposed therebetween.
  • the drum core 16 may be of any suitable type, and usually comprises a grooved cylindrical sleeve secured between the drum flanges 12 and 14.
  • the drum core or sleeve 16 is provided with a plurality of parallel grooves 18 and 20 on the outer periphery thereof and spaced apart by a plurality of arcuate or helical grooves 22 and 24.
  • the parallel grooves 18 and 20 cooperate with the arcuate or helical grooves 22 and 24 to provide a continuous combined parallel and helical groove around the sleeve 16 and extending from one of the flanges 12 to the other flange 12, generally similar to that depicted in the FL.
  • the set of parallel grooves 18 is separated from the set of parallel grooves 20 by the two separate control or pitch areas 22 and 24, and each set of parallel grooves 18 and 20 may extend around the circumference of the sleeve 16 through any variable distance in accordance with the desired grooving system for the drum.
  • control bars or end fillers 26 and 28 are preferably secured adjacent the inner face of the drum flanges 12 and 14, respectively, as is well known, for facilitating guiding of the cable into the groove during the initial winding or winding of the first layer of the cable around the sleeve 16.
  • control bars or kicker members may be secured to the inner face of the drum flanges 12 and 14 for utilization in the well known manner to facilitate the reversal of the cable at the beginning of each succeeding layer during the cable winding operation.
  • the kicker members are not required in some types of installation.
  • An aperture 30 may be provided in the drum core 16, as shown in FIG- URE 1, or may be provided in one of the drum flanges, if desired (not shown), for anchoring one end of the cable or line 32 which is to be wound onto the drum 10.
  • the set of arcuate grooves 22 are of a configuration for moving or directing the cable 32 from the parallel grooves of set 18 into the corresponding parallel grooves of set 20.
  • the set of arcuate grooves 24 are of a configuration for moving or directing the cable 32 from the parallel grooves of set 20 into the corresponding parallel grooves of set 18.
  • the parallel sections 18 and 21 are arranged in such a manner that the parallel grooves thereof are offset one-half pitch, or spaced onehalf pitch apart, it is to be understood that the parallel grooves may be arranged in substantially any desired offset arrangement.
  • FIGURE 6 illustrates a drum 10A having the usual drum flanges 12A and 14A provided with a grooved drum core 16A secured therebetween.
  • the drum core 16A is provided with a plurality of parallel grooves 18A having a plurality of arcuate or helical grooves 34 interposed therein.
  • the arcuate groooves 34 are of a configuration for moving or directing the cable from one parallel groove 18A to an adjacent groove 18A, thus resulting in an ofiset arrangement substantially equal to one full pitch or one full groove width.
  • the usual end filler members (not shown) and kicker members may be utilized on the drum flanges 12A and 14A if desired, as is well known.
  • each set of grooves 22 and 24 are cut away or recessed in such a manner that the lower surface of each of the grooves 22 and 24 is disposed lower than the lower surface of the grooves 18 and 20.
  • the diameter D1 of the core 16 at the pitch areas 22 and 24 (or the independent radii thereof) is less than the diameter D2 at the parallel areas 18 and 20.
  • the individual wraps 42 thereof cross over the wraps 36 of the first layer at each pitch area 22 and 24 and exert a downward or radially inwardforce as indicated by the arrow 44. Since the wraps 36 are not in engagement with the lower surface of the grooves of the pitch areas, there is no opposite or opposing force acting against the force 44. Thus, there is substantially no crushing effect or force exerted on the inner layers of cable as the cable is wound in succeeding layers around the core 16.
  • the lowered position of the pitch areas 22 and 24 provides a soft cross-over for the spooled cable and as the cable is wound on the core 16 in multiple layers, any build up of the cable at the cross-over areas is substantally eliminated or greatly reduced because of the fact that the cable is suspended between the points 38 and 40, allowing the cable to give or yield at the pitch or cross-over areas.
  • the outer periphery of the core 16 having the cable wound thereon is maintained at substantially the same diameter Without any build up areas for substantially precluding or eliminating any out of balance condition during the spooling operation.
  • the pitch area 34 of the embodiment disclosed in FIGURE 6 is also of a lowered position similar to the pitch areas 22 and 24, thus providing a soft or yieldable cross-over area for the drum 10A with the resulting improvements in the cable spooling operation.
  • the pitch areas may be disposed at substantially any desired spacing around the outer periphery of the drum core.
  • a cable spooling drum 50 is depicted therein which comprises a cylindrical core member 52 having the usual drum flanges 54 and 56 disposed at the opposite ends thereof.
  • a pair of spaced arcuate sleeve portions 58 and 60 are spaced around and secured to the outer periphery of the core member 52 in any well known manner, such as by bolting or welding, or the like.

  • the adjacent ends of the sleeve sections 58 anod 60 are spaced apart as clearly shown in FIGURES 3 and 4 to provide a pair of spaced gaps or recess portions 66 and 68.
  • These recess portions are the pitch areas for the first layer of cable to be wound on the drum 50 and it will be apparent from FIGURE 4 that the outer surface of each of the recesses 66 and 68 is lower or of a smaller radius than the lower surface of the parallel grooves 62 and 64.
  • the cable portions disposed in the pitch areas 66 and 68 will be suspended between the spaced ends of the grooved sleeve portions 58 and 60.
