1,046,640. Pivots. FORD MOTOR CO. Ltd. Aug. 26, 1965 [Sept. 30, 1964], No. 36666/65. Heading E2F. A pivot between members 12, 14 of a windscreen wiper linkage comprises a pin 52-57 on the member 12 engaging a brush in a hole 43 in the member 14, the brush being of nylon impregnated with molybdenum disulphide to make it self-lubricating. Lips 25, 26 on the brush press against an abutment surface on the pin and against the member 14 to exert an axial force on the joint. The brush has longitudinal slots therein extending from the end adjacent the head 56 of the pin to enable the brush to compress when it is forced through the hole 43 and to expand when the pin is subsequently forced therethrough. A projection on the brush engages a corresponding recess in the hole 43 to prevent the brush rotating. |
