ELASTIC TERMINAL OF RAILWAY RAIL BOLT-FREE PAD-FREE FASTENING AND UNDER-RAIL GASKET FOR RECESSED UNDER-RAIL AREAS Russian patent published in 2017 - IPC E01B9/48 E01B9/68 

FIELD: construction.

SUBSTANCE: elastic terminal (3) of railway rail bolt-free pad-free fastening comprises seven consecutive sections (31-37). The first and the seventh sections (31, 37) form the legs lying in the plane (P). The second and the sixth sections extend aside and upward from the plane (P). Parts of the third and the fifth sections (33, 35) extend towards the plane (P), while being located above it. The longitudinal axes of the third and the fifth sections (33, 35) lie in the plane (R), which intersects the plane (P) at an acute angle α. The fourth section (34) is located in the plane (P) or below it, and its longitudinal axis lies in the plane (Q) intersecting the plane (P) at an angle β. The under-rail gasket (4) comprises the under-rail area, to the opposite side edges (43) of which the vertical parts (44) are fixed, connected with the projection (45A, 45B) which extends laterally from it. The projection is vertically spaced from the under-rail gasket (42).

EFFECT: possibility of using the terminal and the gasket on recessed under-rail areas.
