Abstract

386,444. Capillaryaction lubricating. MOREBY, G. J., P.O. Box 65, Mufulira Mine, Mufulira, Northern Rhodesia. Jan. 20, 1932, No. 1743. Convention date, Jan. 20, 1931. [Class 12 (iii).] A trolley pulley for collecting electric current is mounted on ball-bearings 16, which are lubricated by wicks 21. The latter dip into oil reservoirs 18 located in the trolley head 9 and pass through a hollow spindle 11 to apertures 19 leading to the bearings. Circumferential grooves 31 may be provided on the spindle to prevent oil pass. ing towards the centre portion thereof.
