  • Patent number: 4386751
    Abstract: A switch point guard for railroad track having a guard or deflector rail positioned to prevent flanges of railroad wheels from striking the switch point. The guard rail is carried on support members for rigid retention in a fixed, predetermined position relative to the track. By this invention the guard rail is carried by horizontally positioned guard rail plate means attached to the side of the guard rail. Apertures are defined in the rail plate means with chock plates positioned in the apertures. The chock plates each define an aperture off center in the direction perpendicular to the guard rail, with the support members defining attached projecting members occupying the off-center apertures. Accordingly, peripheral edges of the chock plates occupy different positions depending upon which side of the chock plates faces toward the rail track. Thus the predetermined position of the guard rail can be varied.
