RAILWAY RAIL FASTENING CLIP AND PAD FOR RECESSED RAILSEATS
摘要:
A resilient railway rail fastening clip (3) has successive first to seventh portions (31 to 37) where, when the clip (3) is in a non-operative configuration, the first and seventh portions (31, 37) of the clip (3) form leg portions which lie in a first plane (P), the second and sixth portions extend substantially away from and above the first plane (P), at least parts of the third and fifth portions (33, 35) extend towards and above the first plane (P) such that the longitudinal axes of the third and fifth portions (33, 35) lie substantially in a second plane (R), different from the said first plane (P), which second plane (R) intersects the first plane (P) at a first acute angle α, and the fourth portion (34) extends substantially in or below the said first plane (P) such that the longitudinal axis of the fourth portion (34) lies substantially in a third plane (Q) which is different to the said second plane (R) and intersects the said first plane (P) at a second acute angle β, where 0°≦β
