Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
79 words
An apparatus for uniformly distributing lubricant over a cable being pulled through a conduit at the entry end of the conduit continuously as the cable moves through the conduit comprised of: an adjustable flanged sleeve; means for releasibly securing the adjustable flanged sleeve to the entry end of the conduit with the flange projecting from the conduit; a ring adapted to be mounted on the flange; and a plurality of nozzles located equidistantly around the ring facing the cable.
Claim 2
Independent Claim
79 words
An apparatus for uniformly distributing lubricant over a cable being pulled through a conduit at the entry end of the conduit continuously as the cable moves through the conduit comprised of: an adjustable flanged sleeve; means for releasibly securing the adjustable flanged sleeve to the entry end of the conduit with the flange projecting from the conduit; a ring adapted to be mounted on the flange; and a plurality of nozzles located equidistantly around the ring facing the cable.
Claim 3
Dependent Claim
25 words
An apparatus as in claim 1 further comprising a recess in the interior of the ring in which the flange of the adjustable sleeve fits.
Claim 4
Dependent Claim
106 words
An apparatus as in claim 1 further comprising: a first and second nozzle surface for each nozzle which surfaces are arranged at an angle of 90° to each other with the first surface oriented at an angle to the cable directed toward the interior of the conduit; a passage for lubricant terminating in an opening in the first nozzle surface; a passage for air terminating in the second surface; means for directing lubricant through the lubricant passage; and means for directing air through the air passage to deliver lubricant over the first nozzle surface at an angle to the cable toward the interior of the conduit.
Claim 5
Dependent Claim
