RAIL FASTENING (VERSIONS), DEVICE FOR FASTENING RAIL ON BASE (VERSIONS) AND PERMANENT WAY (VERSIONS) Russian patent published in 2008 - IPC E01B9/00 E01B9/30 E01B9/38 E01B9/68 F16B39/34 E01B1/00 E01B2/00 

FIELD: railway transport.

SUBSTANCE: anchor of rail fastening is made with inclined posts meeting at top, or with inclined cantilever. Widened to top part of rod for engagement with side faces of adjuster hole is fitted in clamp stress adjuster hole made widening in plan towards rail. Longitudinal cavity with side faces narrowing towards bottom are made on lower face of adjuster at each side of hole, end leg of clamp being fitted in each, with clearance between leg and bottom of cavity. In rail fastening device, lower section of nonflexible C-shaped layer of side section of rail gasket on each end face is made with projection pointed downwards and orientated across rail to enclose base faces orientated across rail. Gasket is placed at each side of rail between side face of longitudinal rail cavity and side section of rail gasket to adjust gauge, with projection on each end face crosswise directed to outer side from rail which encloses crosswise orientated side faces of base with said projection to engage with said faces of base. Gasket to adjust gauge is located in permanent way in mating of each side face of rail cavity and flexible gasket. Gasket to adjust gauge has side face with irregularities. Said section of each plate of permanent way is provided with longitudinal projection from outer side on each rail cavity.

EFFECT: possibility of mechanization of mounting and demounting operations and adjustments in operation of rail fastenings, prevention of longitudinal shifts of rail relative to base and possibility of adjustment of gauge within required limits.
