Abstract
A top plate (5) for an elastomeric rail fastening assembly has a downwardly tapering lower wall (22) terminating in an inwardly-directed lip (25) defining a mouth (26) leading into a well (24). The cavity of the well (24) extends upwardly to provide the interiors of rail-holding mounts (10) between which a bottom flange of a rail may be located. The mounts (10) have open-ended sockets (11) for receiving spring clips used to hold the rail in position between the mounts (10), and the sockets (11) and well (24) communicate with one another. This form of top plate allows less metal to be used for its construction, requires less dressing after casting, and, precisely locates the sockets with respect to one another.

The specific embodiment
Assembly 1 shown in Fig. 1 links to each other with the track substrate by screw (not shown), and described screw is passed down through in four holes 2 in the attaching clamp 3, and lug 3 is arranged in pairs in each side of the base plate 4 of assembly.Base plate 4 is made by cast iron.One cast iron top board 5 is installed in the central authorities of the perforate on the upper surface of base plate 4, and be fixed on the appropriate location by the thick-layer 6 of elastomeric material such as rubber, described elastomeric material is clipped in respectively between the fi-ustoconical surface relative, that separate on two plates 4 and 5.Fi-ustoconical surface 5 is tapered downwards.Layer 6 hardens on two boards 4 and 5.
One track 7, with dashed lines is schematically illustrated, it has a root edge 8 between two spaced apart clip installed parts 10, described clip installed part 10 from top board 5 to upper process and with the top board monoblock cast.Each installed part 10 is formed with jack 11 level, open-ended, is used to receive an end of elasticity rail geometrical clamp 12 (being shown in broken lines).Another end of clip 12 is crossed installed part 10 then, and is formed with horizontal terminal part always around the back of installed part 10, and this part leans against on the inclined plane 13 track flange 8 downwards, and extend between installed part 10 on this inclined plane.The inclination angle of face 13 provides track 7 required inclination.
