  • Patent number: 5984571
    Abstract: A vibrating screed is provided which permits selective adjustment of the angle between the axis of a rotatable eccentric and the plane defined by the bottom of the screed plate to vary the relative vertical compaction and horizontal smoothing oscillation movement imparted by the eccentric. The screed includes a frame, motor, an eccentric driven by the motor, a screed plate, and a pair of locking hinges which releasably connect the frame to the screed plate at one of a multiplicity of possible angular relationships therebetween. The screed plate includes a tension adjustment to facilitate leveling of the screed and the weight of the eccentric is positioned between two spaced-apart bearings for enhanced support and for enabling the axis of rotation of the eccentric to be varied relative to the screed plate.
