ABSTRACT:
A nozzle for directing a flow of lubricant particles vertically downwardly onto the surface of a disc moving horizontally across the discharge opening of the nozzle includes a pair of side plates which are secured together by end plates to form an enclosure having a narrow discharge opening at the bottom edge. The side plates are substantially in the form of isoceles trapezoids having a bottom edge wider than its top edge and having the end plates extending between the nonparallel edges of the side plates. An inlet port is connected to the top edges of the plates. The side plates have on their inner surfaces adjacent their bottom edges a groove which extends along the bottom edges to the end plates. The grooves are adapted to catch any lubricant which flows down the inner surfaces of the side plates and direct such lubricant to the ends of the discharge opening where the lubricant can drip from the nozzle.
