Abstract

This cast steel crossing with movable point is characterized in that the heel portion of the point is clamped on a triangular boss projecting from the crossing proper on which it can swing from one position to the other position, and that a horizontal key having a part-spherical central portion is provided for holding said heel portion of the point on said crossing boss, in order to eliminate the so-called "gap" section in the central portion of the crossing and therefore avoid the abnormal stress heretofore exerted on the wheel tires on account of the insufficient rolling surface of conventional crossings.
