摘要： 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.

摘要： A resilient rail fastener assembly for curved tracks includes a unitary base plate adapted to receive a load carrying rail which includes a pair of planar brace plates for maintaining the rail in a vertical orientation and reducing noise and vibration. More particularly, the rail fastener assembly includes a unitary base plate having an upstanding shoulder disposed on one side thereof, and a pair of spaced, planar upstanding brace plates disposed on the other side thereof and formed integrally with the base plate. An elastomeric pad is positioned between the base plate and the bottom of the rail, with the brace plates being disposed transverse to the longitudinal axis of the rail. The upper portion of each brace plate is disposed in abutting relationship with the upper portion of the rail. By this arrangement, centrifugal forces imparted to the curved rail by the movement of rolling stock, are transferred from the rail, through the brace plates and the base plate, and into the road bed, thereby maintaining the rail in a vertical orientation and reducing unwanted noise and vibration. In an alternative embodiment of the subject invention, a parallel guard rail is mounted between the load carrying rail and the brace plates. In the latter embodiment, the rail fastener assembly further includes a wedge which is fixedly connected to the base plate and interposed between the brace plates and the guard rail, with the wedge abutting the upper portion of the guard rail. By this arrangement, the centrifugal forces imparted to the guard rail by the rolling stock are transferred from the guard rail through the wedge and brace plates into the ground thereby maintaining the guard rail in a vertical orientation.
