Abstract 806,105. Roller bearings. BRITISH TIMKEN, Ltd. May 31, 1957 [Aug. 20, 1956], No. 25319/56. Class 12 (1). In an axle-box assembly, a sleeve 2, constituting outer races for rollers 3, is counterbored at its ends to receive annular sealing rings 9 which are retained by U-shaped wire staples 16 passing through spaced parallel holes 15 in the sleeve 2 and having their ends located in annular clearances between the inner surface of the sleeve 2 and outer surfaces 11, of reduced diameter, of the rings 9. The wire is of copper, brass or other similar ductile material to facilitate removal of the rings. In a modification, shown in Fig. 5, the ring 9 has a curved corner 18 which deflects the ends of a staple 16 outwardly when it is inserted through the hole 15<SP>1</SP>. In a further modification, a split cotterpin 20, Fig. 10, is used instead of a staple.
