<p>A clip for securing a rail seal element to a rail includes a generally L-shaped first clip member having a clamping arm and an elongate connector arm extending from one end of the clamping arm and capable of passing under the rail; a second clip member removably slidable on the connector arm; and a locking mechanism capable of releasably locking the second clip member against sliding movement along the connector arm. In use, the second clip member is removed from the connector arm so that the connector arm can be passed under the rail with minimum disruption of the ballast. The second clip member is then slid back onto the connector arm, and the assembled clip then oriented so that the rail and the rail seal are positioned between the clamping arm and the second clip member. The second clip member is then slid on the connector arm toward the clamping arm so as to tightly press the rail and rail seal therebetween. Finally, the second clip member is locked onto the arm to prevent the clip from releasing the rail and rail seal. A tool for setting the clip includes a lever arm, and cam body and a pivot pin mounted on a nose of the cam body. By this means, movement of the second clip member toward the clamping arm is caused by inserting the pivot pin into a tool notch on the first clip member and thereafter pivoting the tool, about the pivot pin, toward the clamping arm. Subsequent pivoting of the tool away from the clamping arm causes the locking mechanism to automatically engage to prevent the second clip member from moving away from the clamping arm.</p> |
