ABSTRACT:
A rail fastener includes a shoulder member fixed relative a cross-tie and having a head insertable through an apertured insulator. One end of the insulator bears upon the cross-tie while the opposite end carries a dielectric pad engaging the top surface and lateral edge of a rail base flange. The fastener assembly is completed by the application of a spring clip attached to the shoulder head and constantly bearing downwardly against the two opposite ends of the insulator. The dielectric pad surrounds a substantial portion of one end of the insulator and preferably is staked thereover but alternatively may be secured by a press fit, shrink fit, snap fit or by suitable adhesive.
