Patent ID: 6923381

Claim:
A railway rail fastening assembly for fastening a railway rail ( 1 ) to an underlying rail foundation ( 2 ), the assembly comprising: a pair of railway rail fastening clips ( 3 ), each clip ( 3 ) having a first portion ( 33 ), serving as a toe portion ( 33 ) for bearing on the railway rail ( 1 ), and a second portion ( 32 ) for engaging a rail fastening clip anchoring device ( 4 ) secured to the rail foundation ( 2 ), the clip ( 3 ) being capable of being retained in the assembly in a pre-assembly position in which the clip ( 3 ) does not bear on the rail ( 1 ); a pair of electrically insulating toe insulators ( 5 ), each insulator ( 5 ) having a cavity ( 51 ) within which the toe portion ( 33 ) of the clip ( 3 ) is located, whereby the clip ( 3 ) is electrically insulated from the rail ( 1 ), the insulator being retained on the toe portion ( 33 ) of the clip ( 3 ) by insulator retaining means ( 34 A, 34 B) provided on the toe portion ( 33 ) of the clip ( 3 ) which engage corresponding means ( 52 ) on the insulator ( 5 ); and a pair of rail fastening clip anchoring devices ( 4 ), each anchoring device ( 4 ) having a passageway ( 45 ) within which the second portion of the clip ( 3 ) is located when the clip ( 3 ) is bearing on the rail ( 1 ); characterised in that each clip ( 3 ) is formed of an elongate plate shaped such that a central region ( 31 ) of the plate has in profile the form of a letter C, a first end region of the plate extending from one side of the central region ( 31 ) to form the second portion ( 32 ) of the clip ( 3 ), which serves as a base portion ( 32 ), and a second end region of the plate extending from the opposite side of the central region ( 31 ) of the plate to form the said toe portion ( 33 ) of the clip ( 3 ); and in that an upper surface ( 441 ) of each anchoring device ( 4 ) is formed with a step ( 442 ) which engages the toe insulator ( 5 ) to Inhibit unintentional removal of the clip from the device ( 4 ) when the clip is in its pre-assembly position.
