Abstract
A cable is passed through a lubricant filled chamber comprising an open housing and first and second flexible, annular discs each having radial slits along its inner circumference. A third flexible annular disc adjacent to said second disc includes radial slits on its inner circumference rotatably displaced from said second disc slits. The inner circumferences of the discs deformably engage the cable whereby lubricant beads are deposited at the second disc, which beads are uniformly spread by the deformably engaged sections of the third disc.
Claims1
Apparatus for applying lubricating material to extended lengths of cable preparatory to pulling through narrow conduits comprising
- a substantially cylindrical housing open at both ends for enclosing a section of cable to be lubricated,
- a plurality of flat flexible annular discs having a central opening defined by an inner circumference smaller than the outer circumference of cable to be lubricated and at least six uniformly spaced slits extending radially outward from said inner circumference toward but short of an outer circumference,
- means for facilitating the uniform spreading of beads of lubricating materials over the outer surface of a cable being lubricated further comprising
- first means for fixedly attaching at least one of said discs to close off the cable entrance end of said housing, and
- second means for fixedly attaching a first and a second of said discs in concentric juxtaposition with said six or more radial slits being staggered uniformly from disc to disc and the second disc which is the outermost disc being relatively more flexible than said first disc to close off the cable exit end of said housing whereby said first disc forms and said second disc uniformly spreads said beads of lubricating material.
