  • Patent number: 4828427
    Abstract: A cement screed tool includes bracket clamps designed to be attached at each end of a long two-man screed, with pivotable handles being attached to each of the clamps. Operators can grip each combined handle and bracket assembly with both hands while standing sideways to the screed, inasmuch as the pivotable handle arrangement includes a pair of spaced-apart hand grips. One of the hand grips is positioned above and the other hand grip is positioned rearwardly of the screed, with selective pivoting of the handles then being permitted by the operators. The specific positioning of the hand grips relative to the screed board facilitates an accurate and efficient control of the screed by an operator.
