ABSTRACT:
A railroad track fastener assembly consisting of a spring plate and a resilient seat for a railroad rail comprising a pad of resilient material positioned between the rail base and the base of a spring plate. The spring plate may be bolted to any type of cross tie or foundation of concrete, steel, or wood. The pad of resilient material is formed with a plurality of spaced vertical holes and is either bonded to the base of the spring plate and is freely positioned within the spring plate. The pad is retained within the spring plate by spring shoulder clips that are secured to the spring plate shoulders resiliently checking the upward motion of the rail under a heavy load. Guard rails and braces are provided for maintaining the wheels of rolling stock on the rails while rounding curves. Accordingly, the rail seat assembly of the subject invention is in effect a railroad track direct fixation spring plate fastener which is operative to achieve noise and vibration attenuation; resistance to rail wave action stress and tie twisting, and is also adaptable for variation in the gage of the rails.
