ELASTIC BOLTLESS RAIL FASTENING-3 Russian patent published in 2021 - IPC E01B9/48 

FIELD: railways.

SUBSTANCE: invention relates to railway transportation, in particular, to the construction of the railway track superstructure. The elastic boltless rail fastening comprises embedded parts mounted on the track base, terminals pressing the rails to the track base through elastic and insulating plates made of plate-like spring steel in the form of a "uniform strength beam". The terminal has a variable width along the length thereof from the support site in the embedded part with a narrowing to the support site thereof on the rail base. The embedded parts have protrusions above the surface of the track base, covering a part of the terminal, wherein the protrusions are made with an internal profile following the configuration of the curved part of the terminal inserted latching into the embedded part.

EFFECT: efficiency of rail fastening is increased and holes no longer need to be made in the terminal as a result.
