Elastomeric mounting for railway rail with differently angled flanks

Abstract

A mounting for one rail of a pair of railroad rails having inner sides turned toward each other and outer sides turned away from each other comprises a base supported on the ground under the one rail and formed with an upwardly open recess having inner and outer base side flanks respectively generally under and parallel to the inner and outer sides and end base flanks extending between the side base flanks and transverse to the rail. These side flanks form with the vertical an angle normally between 0.degree. and 10.degree. different from the angle of between 15.degree. and 80.degree. of the end flanks. An insert is attached to the rail, received in the recess, and has respective side and end insert flanks juxtaposed with, generally parallel to, and spaced from the respective base flanks. Respective side and end elastomeric bodies lie between the base and insert flanks and supporting the insert in the recess of the base.
