Abstract: A track-mounting assembly secures a longitudinally extending rail direction to a substrate and has a frame fixed to the substrate and a track plate fitted in the frame. A vertically throughgoing aperture of the frame has an inner edge formed by a longitudinally extending gauge surface directed transversely toward a field side of the assembly and a transversely oppositely directed and longitudinally extending field surface. The track plate carries the rail and has an outer edge is itself formed by a longitudinally extending field surface spacedly transversely confronting the gauge surface of the aperture and a longitudinally extending gauge surface spacedly transversely confronting the field surface of the aperture. The field surface of the track plate is of substantially greater area than the gauge surface of the aperture. An elastomeric mass fills between the frame and the track plate.

Abstract: A direction-fixation mount secures a track assembly to a flat upper surface of a fixed substrate. The track assembly includes a flat plate having a pair of opposite end edges, a track sitting on the plate, and fasteners securing the track to the plate. The direct-fixation mounting assembly has an elastomeric pad of predetermined stiffness underneath the plate and atop the surface so that the track and plate bears downward via the pad on the surface, and a pair of end restraints each having a rigid outer part fixed to the substrate offset outward from a respective one of the end edges of the plate, a rigid inner part spaced inward from the outer part and fixed to the respective outer end edge of the plate, and an elastomeric mass separate from the pad and fixed to and between the respective inner and outer parts.

Abstract: A rail-mounting assembly has a base frame formed unitarily with a pair of side members and a pair of end members generally bridging ends of the side members and having inwardly directed generally vertical inner end faces. At least one web extending horizontally between the members has a horizontal upper face and defines with the members a vertically throughgoing aperture. A top plate spaced above the base frame has a lower face having a portion spacedly vertically confronting the upper face of the web and a pair of outwardly directed outer end faces longitudinally horizontally confronting the inner end faces of the end members. An elastomeric body is bonded to each of the outer end faces and the respective confronting inner end face and to the upper face of the web and the portion of the lower face confronting the upper face.

Abstract: A rail-carrying plate lies on an upper surface of a base. An anchor-bolt assembly has an elastomeric buffer sheet between the rail plate and the base upper surface and a bolt set in the anchor sleeve passing through the rail plate. An inner ring surrounds the bolt, bears directly on the base surface, is pressed downward by the bolt against the base surface, has an annular outwardly directed outer surface. An outer ring is transfixed by the bolt, has an annular inner surface spaced outward from the inner-ring outer surface, and bears upward on the rail plate. An annular elastomeric body between the inner and outer rings is bonded to the respective outer and inner surfaces thereof so that vertical displacement of the outer ring relative to the inner ring tends to self-center the two rings.

Abstract: A rail-mounting assembly has a generally rectangular base frame formed with a window and having a pair of diagonally opposite abutments at respective ends of the window and having downwardly and inwardly inclined faces. A top plate in the window has a lower face above a lower face of the frame, a pair of bosses projecting upward from the top plate and each juxtaposed with a respective one of the abutments and each having a downwardly and inwardly inclined face spacedly juxtaposed with the downwardly and inwardly inclined face of the respective abutment. A one-piece elastomeric body is bonded to and interposed between the inclined faces of the frame and of the top plate.

Abstract: A track fastener has a top plate spacedly surrounded by a frame and connected to the frame by a body of elastomer bonded to both the top plate and the frame at all surfaces at which the elastomer fills the gap between the two. The frame has hoods overhanging ribs of the elastomer which have inclined flanks covered by the elastomer as the elastomer reaches down from the gap between the hood and the rib to the top surface of the top plate lying below the receiving surface of the top plate on which the rail bears.

Abstract: Rail mounting assembly of the type in which a top plate is secured to a frame by an elastomer body surrounding the top plate and bonded to both the top plate and the frame. The rounded ends of the top plate and frame receive the elastomer in gaps between downwardly and inwardly inclined surfaces while the elastomer between the longitudinal flanks of the frame and top plate has downwardly open voids which are narrower toward the end of the top plate and wider at a midpoint.
