Abstract: 431,183. Lubricating the wheel flanges of rail vehicles. DE LIMON FLUHME & CO., 1, Industriestrasse, D³sseldorf, Germany. Feb. 2, 1935, No. 3476. Convention date, Feb. 5, 1934. [Class 12 (iii)] In means for lubricating the wheel flanges of rail vehicles, wherein the lubricant is delivered by the pumping elements 4 of a pump to a number of nozzles 1 and is atomized and sprayed upon the wheel flanges at the same time by compressed air delivered to the nozzles 1 by pipes 3 from a reservoir 5, the supply of air to the pipes 3 is effected by a rotary valve 10. The latter is driven by the shaft 9 actuating the pump, and has a delivery aperture 16 always open to an intermediate air reservoir 7 and which in turn registers with outlets 14, 15, leading to the pipes 3. The valve cylinder 8 has ports 12 corresponding in number to the outlets 14. Air from the reservoir 5 passes to an annular groove 11 in the cylinder 8, and, as the valve rotates, a recess 13 therein registers in sequence with the ports 12 so that the intermediate air reservoir is charged with air under pressure. At the same time the air in the reservoir 7 passes through the delivery aperture and in turn to the pipes 3. The ports 12 are staggered in respect to the outlets 14, or the recess 13, ports 12, and outlets 14 may be arranged other than as shown, so that, should the vehicle come to rest with the delivery aperture 16 and an outlet 14 in register, only the air in the intermediate reservoir 7 is exhausted through the outlet 14. The dimensions of the outlets 14, 16, are such that air starts to issue from the nozzles 1 before, and ceases to issue after, oil is delivered through the nozzles by the pumping elements 4.
