Patent number: 10844555Abstract: A power unit is configured for use as part of a concrete screed and includes a frame, a powered drive, and a drive coupler. The frame includes a drive housing and a handle to be grasped by a user, with the handle being configured to facilitate manual advancement of the concrete screed in the forward direction. The handle and the drive housing are pivotally attached relative to each other so that the handle is swingable relative to the drive housing about a pivot axis that is transverse to the forward direction. The powered drive is operably supported by the drive housing and includes a rotatable drive shaft. The drive coupler is attached to the drive shaft and is removably attachable to the connection shaft of a rotatable concrete forming drum so that rotation of the drive shaft is imparted to the connection shaft.Type: GrantFiled: September 4, 2019Date of Patent: November 24, 2020Assignee: Curb Roller LLCInventors: Kraig Allen Pyle, Seth Nathaniel Ulmer, John Allen Armstrong

Patent number: 8297878Abstract: A curb forming machine for use by a single operator to form curved curbing includes a single rotatable curb-forming roller, a handle assembly for pulling and maneuvering the roller, and a motor for rotating the roller. The roller includes a generally cylindrical body, a neck at one end of the body, and a shaping surface, all of which are coaxial. The motor rotates the roller so that the lower periphery of the roller moves toward the direction of pulling to shape and smooth wet concrete into curbing. An overflow guard prevents wet concrete from flowing over the roller onto the finished curb, and an alignment device extends outwardly from the roller to contact a form member. A curb forming method includes pulling and steering such a roller around a curved form, including around tight curves in the form.Type: GrantFiled: October 1, 2009Date of Patent: October 30, 2012Assignee: Curb Roller LLCInventors: Michael J. Goodman, John A. Armstrong
