In the assembly of permanent way crossings, the heads and nuts of the transverse bolts which hold the various parts together must tighten on varying angles of seating. Hitherto this has meant using a variety of taper washers to suit the different angles of crossings and bolt positions. To obviate the necessity for using so large a number of different types of washers, a universal washer consisting of two parts having spherical seats has been devised. This washer assembly incorporates the ball-and-socket principle, and the auxiliary washer maintains the bolt alignment irrespective of that of the main washer.
