    摘要： An improved method and apparatus for proportionately metering and selectively applying lubricant to the inner surface of a conduit as a function of the conduit curvature, to facilitate subsequent pulling of cables therethrough, is disclosed. A spreading device, when pulled through "straight" conduit sections, meters and applies lubricant in longitudinally extending spaced strips of uniform thickness around the inner circumference of the conduit. Upon approaching a curvature or bend in the conduit, pulling tension force vectors transmitted to the spreading device in the radial direction tilt the spreading device to non-concentric alignment in the conduit, causing the spreader to disproportionately apply increased quantities of lubricant to that surface of the conduit having a shorter bend radius, where such lubricant is most needed to reduce frictional sidewall forces applied to the pulled cables. When tilted, the spreader simultaneously reduces the amount of lubricant applied to the conduit wall having the longer bend radius, where such lubricant is needed least. The spreading device is of symmetrical construction, having a frusto-conical forward section, a cylindrical trailing portion and a plurality of inclined rib members that perform the lubricant metering functions. The spreader device is sized and configured to provide the desired lubricant application functions. Use of the spreading device and method of this invention enables accurate predictions to be made on the volume of lubricant that will be needed to fully complete a conduit lubrication application, even over conduits of extended length and having multiple curvatures and bends.

    摘要： A cable lubricating device (1) including a split housing (2). Lubricant (25) is introduced into the housing through a vertically oriented orifice (6), the cable (37) advancing in a generally horizontal direction. A coupling adaptor (59) permits withdrawl of lubricant by a standard fitting (64) without danger of the collapse of hose (56) even at high lubricant discharge pressures. A series of sponges (18, 19) apply lubricant to the cable in a metered fashion. A method is also disclosed wherein lubricant may be "preloaded" into conduit (26) to enhance uniform lubricant distribution.

    摘要： A method of installing lightweight cable in a conduit by placing a leakproof tubing in a conduit, joining the sections of tubing together to make a continuous length of tubing and attaching to one end of the tubing a fitting having a liquid tight passage for sliding cable therethrough and an inlet passage for pumping fluid into the tubing. Fluid under pressure provides a lubricant while forcing a pulling plug through the tubing. A lightweight cable attached to the pulling plug pulls the lightweight cable through the lubricating fluid in the tubing without breaking the cable. If the fluid used is liquid it is removed from the tubing by using pressurized gas to force a wiper plug along the cable and inside of the tubing.The apparatus of the invention includes a deformable pulling plug that slides along the inside of tubing, pulling the lightweight cable therewith. A deformable wiper plug is provided having an opening for sliding along the cable and inside the tubing to forceably remove liquids in the tubing.
