ABSTRACT:
An improved end-seal carrier assembly for supporting a seal in a seal-type continuous dampener. The seal is supported by a backing plate and pressed against the ends of the dampener's rollers. A carrier shaft is fixedly mounted to the backing plate. A shaft housing is mounted to the sideframe and has a hole extending longitudinally there through into which the shaft is mounted so to rotationally and longitudinally translate with respect to the sideframe. A coil spring is wound about a portion of the carrier shaft and has a first spring end operatively engaging the backing plate and a second spring end operatively engaging the shaft housing. The coil spring is configured to induce both a compressive and torsional bias between the backing plate and the sideframe. The shaft housing is rotatable for winding the coil spring and thereby establishing the torsional bias.
