SLIDING CLAMP OF AERIAL CROSSING Russian patent published in 2007 - IPC B60M1/14 

FIELD: railway transport; electrified railways.

SUBSTANCE: invention relates to contact systems of railways employing aerial crossing. Sliding clamp of aerial crossing has two opposite jaws with flat surfaces and with curvilinear chutes on free ends of which teeth are made, and member for attachment of hanger and for adjusting jaws-to-jaw distance. Chute of each jaw is made widening from middle section to edges of jaw, and middle section of chute is made in form of segment of curvilinear surface whose axis is parallel to flat surface of jaw, and widening sections are made in form of segments of curvilinear surfaces non-coaxial with axis of middle section. Hanger attachment and adjusting member is made in form of strip with holes for bolt joint and for hanger, clamped from one side between flat surfaces of jaws. Middle section of chute of each jaw is made, preferably, in form of segment of cylinder surface whose axis is parallel to flat surface of jaw, and widening sections are made in form of segments of surfaces of cylinders noncoaxial with axis of middle section.

EFFECT: simplified design, improved reliability, facilitated mounting and reduced overall dimensions and mass.
