  • Patent number: 6174105
    Abstract: A strike-off device is for a paving screed having a main screed and a screed extension attached to the main screed, the screed extension having a generally vertical front surface. The strike-off device includes a plate disposed frontwardly of and adjacent to the screed extension. The plate has a generally horizontal working edge extending laterally along the front vertical surface of the screed extension. Two connective members extend between the strike-off plate and the screed extension and are configured to adjustably attach the plate to the screed extension, such that vertical displacement of the connective members adjusts a vertical position of the strike-off working edge. Preferably, the connective members are each a threaded rod having a first end engaged with the strike-off plate and a second end engaged with the screed extension, such that rotation of the rods displace the strike-off plate in vertical directions.

  • Patent number: 6106192
    Abstract: A material flow modifying device is for a screed assembly of a paving machine. The screed assembly has a main screed with a central axis extending in a direction of intended travel of the paving machine and two screed extensions movably mounted to the main screed. The flow modifying device includes a deflector member connected with the screed extension and having a flow surface facing toward the central axis of the main screed. The flow surface is contactable with paving material on a base surface and is configured to displace the material toward the central axis when the paving machine moves in the intended travel direction. The deflector member has a first end disposed adjacent to the inner vertical surface of the screed extension and a second, free end disposed proximal to the front vertical surface of the main screed, such that the second end moves laterally along the main screed during movement of the screed extension.
