Abstract
A screed assembly for use in paving material upon a generally horizontal surface includes a main screed having a generally vertical front surface. At least one and preferably two screed extensions are connected with the main screed. At least one and preferably a pair horizontally-extending support members each have a first end movably connected with the main screed and a second end connected with a screed extension. The support members are movable with respect to the main screed so as to displace the screed extensions alternately toward and away from the main screed front surface so as to adjust the angle of attack of the screed extensions independently of the angle of attack of the main screed. Preferably, an adjustment assembly or device is connected with the support member and is configured to displace the support member with respect to the main screed. The adjustment device includes a base attached to either the main screed or the support member, preferably the support member. A horizontally-extending rod has a first end attached to the other of the main screed or the support member and a second end movably engaged with the base. Movement of the rod with respect to the base displaces the screed extension alternatively toward and away from the front surface of the main screed so as to adjust the angle of attack of the screed extension.
