RAIL FASTENING SPRING CLAMP Russian patent published in 2005 - IPC

FIELD: railway transport; permanent way.

SUBSTANCE: invention is designed for use in rail-to-tie intermediate fastenings. Proposed spring clamp is made of resilient material bar in form of B section in clamp plane containing straight-line on-rail section whose ends are smoothly connected with side extended sections, and arc on-tie sections arranged after them are connected with end sections bent into clamp. Part of each arc on-tie section arranged close to end section is made with bending in plane square to plane of clamp. Value of bend curvature is commensurable with radius of clamp bar. Proposed invention proposed spring clamp whose design ensure distribution of larger part of mounting load to on-rail section which decreases mounting load.
