MANUFACTURE OF TOP PLATE FOR AN ELASTOMERIC RAIL FASTENING ASSEMBLY |
摘要 |
<p>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.</p> |
