ABSTRACT:
A lubricating device is provided for greasing wire ropes and cables comprising a diametrally split housing with clamps to close the housing about the cable. Within the housing is a diametrally split core body of hard elastomeric material having an axial bore through which the cable travels axially. At the center of the core body is an internal cavity through which the cable passes and which is kept supplied with grease under pressure. Toward its ends the core body has two further internal cavities through which the cable passes, which serve to collect surplus grease. Between and beyond the grease supply and collection cavities, the axial bore of the core body is profiled so that each length of it has the form of an internal triangular section or Vee threaded screw thread; except that the directions of the screw thread are mutually reversed in the two halves of the split core body. The minimum diameter of the screw threads is substantially equal to the cable diameter so that sealing contact occurs between the cable and the thread peaks. At its ends, the housing is fitted with scraper plates having central holes, through which the cable passes, of substantially the same diameter as the cable.
