A screening finger assembly having a holder ( 19 ) and a set of generally parallel finger tines ( 16 ) spaced apart in a row and each mounted in cantilever manner in a respective mounting ( 20, 22 ) in the holder ( 19 ). Each tine ( 16 ) has an outboard end ( 17 ), and an inboard end ( 18 ) which is firmly clamped in the respective mounting ( 20, 22 ). The inboard end ( 18 ) of each tine ( 16 ) includes a tapered portion. Each mounting includes a mounting bush ( 20 ) which is securely mounted in position in the holder ( 19 ), and an intermediate load-absorbing sleeve ( 22 ) arranged internally of the bush ( 20 ) and having an internal surface corresponding in shape to the tapered portion ( 18 ) of the tine ( 16 ) which it receives. A fastening means ( 23, 24 ) moves the tapered portion ( 18 ) of the tine ( 16 ) axially into firm clamping engagement with the internal surface of the intermediate sleeve ( 22 ) to clamp the tine ( 16 ) in position. |
