Title: Sprung mounting for overhead conductor rail - with pivoted mounting lever to balance lateral stabilising forces
Inventor: FREIDHOFER HARRY
IPC: B60M1/26
Filed: 1975-08-23
Abstract: The overhead conductor rail (6) is mounted at the bottom of a mounting lever (1) which is suspended under the mounting bar (2) of the catenary on two sets of cables (3, 4). These secure the lateral position of the rail and enable the rail to be laid in a zig-zig pattern. One of the calbes is coupled to a pivot point on the mounting lever and the other cable (4) to the top end of the lever. The top cable is sprung (8) with the spring pressure chosen so that the moment about the pivot point is balanced by the lateral pull of the rail. The spring thus pulls in the same direction as the rail. The system provides a self centering design which is stable in cross winds and which ensures that the horizontal and vertical settings of the rail are maintained.
