Patent ID: 8757340

Claim:
A suspension apparatus attached to a support span member for overhead contact wires subjected to abrupt contact wire angle changes at the crest of a vertical curve for tangent suspension to a suspension wire, comprising: a curve rail bar made of spring material curvable to match the curve of said vertical curve; a plurality of clamps attaching said curve rail bar to said contact wire which curve rail bar is supported at said crest of said vertical curve; first and second eye nuts, each attached to a selected different one of said clamps; first and second hanger wires, each having first and second ends, said first ends attached to said first and second eye nut, respectively; and said suspension wire having first and second ends, said second end attached to the second ends of said hanger wires forming a V-shape of said hanger wires, said second end of said suspension wire attached to said support span member, said curve rail bar being formed in a curve of a varying radius smoothing out said abrupt angle change in said contact wire, said curve rail bar being flexible in nature to conform to curves of different degree, where said curve rail bar bends in a smooth curve from said eye nuts and supports said contact wire in said same smooth curve.
