US Patent 7544012 Power roller screed with multiple screed rollers

A rotating cylinder cement screeding system having a drive assembly and handle at one end for powering and controlling the screeding system. The rotating cylinder is made of tubular screed rollers of varying lengths allowing a user to customize the length of the system to match a specific cement pour. Further, each tubular screed roller is supplied with a male and female end for interlocking with each other and for receiving a variety of add on attachments. The rotating cylinder may also be equipped with a constant velocity type U-joint to allow the rotating cylinder to flex and thus, allow for pours with crowns or valleys, as need by the cement installer.
