THREADLESS RAIL FASTENING AND ITS MEMBERS Russian patent published in 2007 - IPC E01B9/38 E01B9/00 

FIELD: railway transport; permanent ways of main-line industrial, underground transport and street-cars.

SUBSTANCE: invention is designed for fastening rails to rail bases. Proposed fastening contains embedded members and fixing wedge-like members. Each embedded member consists of electric insulating component and main carrying metal component. Upper part of embedded member rests by its electric insulating component onto concave legs of rod spring clamps. Made in lower part of embedded member arranged in upper part of two-leg anchor is slot in direction of track axis into which fixing wedge-like member is fitted through hole in two-leg anchor. Said wedge-like member engages through upper surface with two-leg anchor, and engages through one of steps of lower stepped surface with lower part of slot of embedded member. Carrying metal component of wedge-like member is made T-shaped and is provided with slot in direction of track axis in lower part. Lower inclined surface of slot is orientated at angle α within 10°≤α≤20° to horizon. Electric insulating component of embedded member has two semitoroidal grooves in convex part for contacting with legs of rod spring clamp. Lower inclined surface of fixing wedge-like member is made stepped, with inclined planes in zone of steps. Tilting of planes relative of horizon corresponds to angle α within 10°≤α≤20°, and upper surface is made rounded off to correspond to rounding off in two-leg anchor.

EFFECT: provision of reliable pressing of rail with possibility of adjustment of pressure, reduced labor input at current maintenance and repairs of track owing to exclusion of operations for servicing threaded joints, possibility of adjustment of track gauge and position of rail lines in height.
