ABSTRACT:
A method and apparatus is provided which is adapted for lubricating each of a plurality of bearings in a large multi-station machine or the like, and wherein a single duct extends along the machine, and a branch line extends from the duct to each bearing. A porous oil storage insert is positioned in each branch line immediately adjacent the discharge end thereof. Means are also provided for sequentially delivering to the duct (1) a low pressure airstream with entrained oil mist such that the entrained oil is accumulated in each of the oil storage inserts, (2) an oil free low pressure airstream for cleaning the duct and cooling and cleaning the bearing, and (3) a high pressure airstream for periodically propelling the accumulated oil from the storage inserts and onto the adjacent bearings at high speed. An accurately predetermined quantity of oil may thereby be intermittently supplied to each bearing.
