摘要: An insulator has a platelike body portion and an integral end flange in abutting contact with the top side and the edge of a rail base flange, respectively, and a metal holddown clip or clamp plate is bolted to a concrete tie with one portion thereof in overlying abutting contact with the body portion of said insulator and another portion juxtaposed to said end flange. At each side of the insulator and extending along said body portion and said end flange is a shoulder in closely spaced relation to the corresponding side of said clip to prevent the insulator from moving or twisting from between the clip and the rail in either direction that the rail may tend to move longitudinally during expansion and contraction of the rail and during passage of a train or the braking of a train.

摘要: An elongated resilient clip rectangular in cross section has a flat end bearing portion and an arcuate end portion to engage the lower face of a railway tie and the lower side of a cover plate on a bridge girder. Said arcuate portion has an elongated slot, upwardly through which and through the tie, passes a bolt which has a head at one end underlying said arcuate portion and means at its other end to tense the bolt.
