Abstract
A method for applying lubricant to the surface of a cable in which the cable is inserted into a lubricant filled chamber through the deformably engaged aperture of a first flexible disc. Beads of lubricant from the chamber are applied to the cable surface through a plurality of radial slits cut through a second flexible disc as the cable exits from the chamber. The exited cable passes through the deformable aperture of a third disc having radial slits cut therethrough in rotatably displaced relationship to the radial slits of the second disc to uniformly spread the lubricant beads on the cable surface.
Claims5
A method for applying lubricant to the surface of a cable comprising the steps of attaching spaced first and second flexible annular discs each having a plurality of radial slits cut therethrough disposed along its inner circumference to a housing forming a chamber between said discs, the inner circumferences of said discs defining a cable passageway through said chamber;
- attaching at least one additional annular disc of greater flexibility than said second flexible annular disc having a plurality of radial slits cut therethrough disposed along its inner circumference adjacent to said second annular disc so that the radial slits of said additional disc are rotatably displaced from the radial slits of said second disc;
- feeding said cable of greater diameter than said cable passageway in said discs into said chamber through said passageway from said first disc to said third disc;
- and injecting lubricant into said chamber through an inlet in housing, said lubricant beads being deposited on said cable through the radial slits of said second annular disc and said lubricant being uniformly spread onto the surface of said cable by said additional greater flexibility annular disc.
A method for dispensing a lubricant on the surface of a cable comprising the steps of passing said cable into a chamber filled with a lubricant through the deformably engaged aperture of a first flexible disc;
- applying beads of lubricant from said chamber to the surface of said cable through a plurality of radial slits cut through a second flexible disc at the exit of said chamber as said cable exits from said chamber through the deformably engaged aperture of said second flexible disc which aperture is in communication with said second disc radial slits;
- and passing said exited cable through the deformable aperture of a third disc of greater flexibility than said second disc with radial slits cut therethrough in rotatably displaced relationship to the radial slits of said second disc and in communication with said third disc aperture to uniformly spread said lubricant beads on the surface of said cable.
A method for dispensing a viscous lubricant on the surface of a circular cross-section cable comprising the steps of feeding said cable into a chamber containing said lubricant through a smaller than cable-diameter aperture of a first flexible annular disc having radial slits cut therethrough in communication with said aperture;
- exiting said cable from said chamber through the smaller than cable-diameter aperture of a second flexible annular disc having radial slits cut therethrough in communication with said aperture;
- depositing a plurality of beads of lubricant from said chamber onto the surface of said exiting cable through said second annular disc radial slits;
- and feeding said cable through the deformable smaller than cable-diameter aperture of a third annular disc of greater flexibility than said second annular disc having radial slits cut therethrough in communication with said deformable aperture and in rotatably displaced relationship to said second annular disc radial slits to uniformly spread said lubricant on said cable surface.
A method for dispensing a viscous lubricant on the surface of a circular cross-section cable comprising the steps of passing said cable through the aperture of a deformably engaged first flexible annular disc having radial slits cut therethrough in communication with said aperture into a viscous lubricant-filled chamber;
- depositing beads of the lubricant from said chamber on the surface of said cable through a plurality of radial slits cut through a second flexible annular disc having an aperture therein in communication with said radial slits as said cable exits from said chamber, the edges surrounding said aperture being deformably engaged with the surface of said cable;
- and uniformly spreading said deposited viscous lubricant from said beads on said exited cable surface by passing said exited cable through the smaller than cable-diameter aperture of a deformable third annular disc of greater flexibility than said second annular disc having radial slits cut therethrough in communication with said aperture, which third disc radial slits are rotatably displaced with respect to said second annular disc radial slits.
