Tread Guard Rail Patents (Class 246/441)
  • Patent number: 10731302
    Abstract: Guide rail support (10) intended to withstand forces (F) exerted in a direction (T) transverse to a railway track on a guide rail (5) extending in a longitudinal direction (L) of the railway track. The guide rail comprises: a front face (31) in the transverse direction for supporting the guide rail (5) or an attachment part (23) of the guide rail, a lower face (33) in a third direction (V) substantially perpendicular to the longitudinal direction and the transverse direction, wherein the lower face transversely comprises at least one front section (43) and one rear section (45), and at least one reinforcement rib (35) transversely linking the front face and the rear section. The rear section and the front section respectably define, in a contact plane (P) of the lower face with the rail support, two distinct contact surfaces (47, 49) separated by a section (51) of the contact plane and devoid of any contact with the lower face, while the reinforcement rib spans the said section.

  • Patent number: 4738418
    Abstract: An adjustable switch point guard includes a wear bar rigidly affixed to an adjustment plate. The adjustment plate is mounted on a fixed base plate which is attached to railroad ties. A threaded fastener on one of the adjustment plate or the base plate engages a first pair of bores in the other of the adjustment plate or the base plate to position the wear bar and adjustment plate 54 relative to a switch point and a fixed rail. Additional setes of bores are provided to enable the adjustment plate and wear bar to be moved relative to the base plate.

  • 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.
