SMOOTHING RAIL JOINT PLATE Russian patent published in 2013 - IPC E01B11/34 

FIELD: construction.

SUBSTANCE: middle part of joint plates is installed inside a track for capability of interaction of their upper surfaces with a wheel. At the same time there is a capability of thermal expansion of rails. In the rail joint plate a ledge B is installed between joined rails so that to one rail the ledge is adjoined tightly, and between the second rail and the ledge there is a temperature gap. The upper surface of the ledge is made in the form of a part of the appropriate upper surface of the rail head. At the same time the inner side surface of the plate interacts with the coupled head and foot of the rail. As two joint plates are installed, the ledges connect the heads and feet of rails so that a part of the temperature gap is near one edge of the plate ledge, and the other part - at the opposite edge of the second joint plate ledge.

EFFECT: provision of unstressed movement of vehicles.
