The cable is made of steel and thus requires periodic maintenance to prevent rusting. Such maintenance is comprised of removing surface dirt, rust, and old paint, then painting the cleaned surface.
A typical cleaning device for cleaning braided steel cables is comprised of a housing which positions wire brushes around a cable. When the cleaning device is moved along the cable, the cable is cleaned by the wire brushes. Some cleaning devices apply a cleaning fluid. Prior art cable cleaners can clean the lands of the cable, that is, the outermost parts of the strands, but cannot clean deep inside the grooves between adjacent strands. Also, the wire brushes wear out quickly. Further, debris and cleaning fluids fly out from the cleaning device as environmental contaminants.

Detailed Description
Fig. 1:
A cylindrical member maintenance device is shown in a perspective view in Fig. 1 in an opened position. It is comprised of a housing 10 comprised of two hinged half housings 11 and 12 for closing around a cylindrical member 13, such as a braided steel cable. The cleaner can be used for cleaning other types of cylindrical members, such as pipes. Half housings 11 and 12 are locked together by latches 14 after they are closed around cylindrical member 13.
Split alignment rings 15 and 16 in housing align cylindrical member 13 therein and seal the interior of housing 10 from the outside environment. A split sealing ring 17 is positioned at a first end of housing 10. Sealing ring 17 has a slightly larger inner diameter than those of alignment rings 15 and 16 to avoid touching cylindrical member 13. Rings 15-17 are each comprised of two half rings 19 and 20 attached to respective half housings 11 and 12, so that rings 15-17 can be opened and closed around cylindrical member 13.
Rotary helical brush assemblies 21 and a rotary longitudinal brush assembly 22 are positioned in housing 10 and rotatable about an axis thereof. There may be any number of each type of brush assembly. Rotary helical brush assembly 21 is comprised of coaxial split rings 23 connected by spacers 24 and rotary cylindrical wire brushes 25 in a helical arrangement. Rotary longitudinal
brush assembly 22 is comprised of coaxial split rings 26 connected by spacers 27 and cylindrical wire brushes 28 in a longitudinal arrangement. The brushes in either brush assembly are independently rotatable about their own axle 57. Each brush assembly can be opened and closed around cylindrical member 13.
Nozzles 29 are positioned inside housing 10 in a space between brush assembly 21 and sealing ring 17 for applying a fluid to cylindrical member 13. Nozzles 29 are connected by hoses 30 to a distribution chamber 31 attached to the outside of housing 10. Suction apertures 32 in housing 10 are for connecting to a suction device (not shown) for removing debris and waste fluid from inside housing 10 to avoid contaminating the outside environment.
Fig. 2:
The cylindrical member maintenance device is shown in a closed position around cylindrical member 13 in Fig. 2. A connector 33 extending from chamber 31 is arranged for connecting to a pressurized source of fluid (not shown), such as a cleaning fluid or paint. A valve 34 and a pressure gauge 35 are also connected to chamber 31. When the fluid is sprayed onto cylindrical member 13 by nozzles 29 (Fig. 1), it is contained within housing 10 to avoid contaminating the outside environment.
A suction distribution chamber 36 is connected to suction apertures 29 (Fig. 1). A connector 37 on chamber 36 is for connecting to a suction device (not shown). Loops 18 on housing 10 are for attaching to cables (not shown) for moving housing 10 along cylindrical member 13. Loops 18 are positioned on opposite sides of housing 10 to prevent housing 10 from rotating about cylindrical member 13. When the cylindrical member maintenance device is used for cleaning the steel cable, it may be moved in an upward direction along the steel cable. When the cylindrical member maintenance device is used for painting the steel cable, it may be moved in a downward direction along the steel cable. The painted portion will only travel past sealing ring 17, which has a slightly larger hole than alignment rings 15 and 16 (Fig. 1) to avoid touching the freshly painted portion of the steel cable.
Fig. 3:
A sectional view of rotary helical brush assembly 21 is shown in Fig. 3 positioned around a cylindrical member 13 which in this example is comprised of a braided steel cable with helical strands 38. The number of cylindrical brushes 25 is selected to match the number of strands 38 in the steel cable. Cylindrical brushes 25 are canted (see Fig. 1) to align with helical grooves 39 between helical strands 38 of the steel cable for cleaning grooves 39.
As housing 10 is moved along the steel cable, brush assembly 21 is rotated about the axis of the steel cable as brushes 25 are guided along helical grooves 39. The friction with grooves 39 cause cylindrical brushes 25 to rotate about their own axes independently of each other in a direction opposite the rotation of brush assembly 21 for better cleaning. The rotation of brushes 25 about their own axes also enable to them wear longer because individual bristles are in contact with the steel cable only some of the time.
Fig. 4:
A sectional view of rotary longitudinal brush assembly 22 is shown in Fig. 4 positioned around the steel cable. Cylindrical brushes 28 are aligned with the axis of the steel cable, and are positioned to engage raised portions or lands 40 of strands in the steel cable. Brushes 28 are caused by helical strands 38 to rotate about their own axes.
Fig. 5:
Rotary helical brush assembly 21 is shown split apart in Fig. 5. Split rings 23 are each separable into two halves 41 and 42, and include pins 43 and holes 44 at abutting surfaces for mating with each other. Split rings 23 also include projections 45 extending from the abutting surfaces for attaching canted cylindrical brushes 25 that extend beyond the abutting surfaces. Fig. 6:
A second embodiment of the cylindrical member maintenance device is shown in Fig. 6. It is comprised of a housing 46 comprised of two separable halves 47 and 48 connected by pins 49 and holes 50. Longitudinal rotary cylindrical brushes 51 are positioned inside housing 46 between split rings 52 and 53 at opposite ends of housing 46. Brushes 51 are independently rotatable about their own axle 54. Housing 46 is split apart and closed around a cylindrical member 55, such as a stranded steel cable. Brushes 51 are positioned to engage the steel cable. When housing 46 is moved along the steel cable, brushes 51 are rotated by helical strands 56 of the steel cable.
Although the foregoing description is specific, it should not be considered as a limitation on the scope of the invention, but only as an example of the preferred embodiment. Many variations are possible within the teachings of the invention. For example, different attachment methods, fasteners, materials, dimensions, etc. can be used unless specifically indicated otherwise. The relative positions of the elements can vary, and the shapes of the elements can vary. Therefore, the scope of the invention should be determined by the appended claims and their legal equivalents, not by the examples given.
