A screed head assembly includes a grade setting device and a vibrating member and is movable over the concrete area via the wheeled unit. The screeding machine includes a roller that is rotatably mounted at the screed head assembly and rotatably driven about its longitudinal axis. The roller is rotatably driven by a rotatable drive motor that is operable independently of the vibrating member or grade setting device. The grade setting device or roller plow assembly may be provided as an aftermarket kit for attachment at a screed head assembly of a screeding machine. | 05-05-2016 |
20160122953 | APPARATUS AND METHOD FOR A JOINT DENSITY ENDGATE ASSEMBLY - A joint density assembly adapted for use on a screed. The preferred joint density assembly comprises an endgate having a vertical axis. The preferred endgate comprises a frame adapted to be mounted to the screed, a mounting means adapted to mount the frame to the screed, a pivoting shoe adapted to be pivotally adjusted, and a means for adjusting the pivoting shoe which is adapted to move the pivoting shoe between a retracted position and an extended position. The preferred pivoting shoe is adapted to pivot about the vertical axis of the endgate. A method for increasing the density of an asphalt longitudinal joint comprising providing a joint density assembly and adjusting the pivoting shoe. | 05-05-2016 |
20160122954 | APPARATUS AND METHOD FOR A JOINT DENSITY BOLT-ON ASSEMBLY - A joint density assembly adapted for use on a screed comprising an endgate having a vertical axis, a frame mounted to the screed, a mounting means adapted to mount the frame to the screed, and a fixed shoe, a bolt-on unit mounted to the screed and disposed between the screed and the endgate, and a means for adjusting the bolt-on unit between a downward position and an upward position.

20100189500 | 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. | 07-29-2010 |
20130183095 | SCREED SYSTEM - A screed system, having: a first elevatable rail; a second elevatable rail; a screed bar positioned below the first and second rails and supported by the first and second elevatable rails by respective first and second rotatable hinges, the screed bar moveable along the first and second rails and rotatable relative to the first and second rails at both the respective first and second rotatable hinges. | 07-18-2013 |
20140286707 | SELF-PROPELLED, POWERED ROLLER SCREED DEVICE - A self-propelled power roller screed having two generally parallel tubular screed tubes and powered winching means that cooperatively engage winching cables attached to deadman structures to advance the roller screed. Screed tube power means spin each of the screed tubes in a direction opposite a direction of travel of the roller screed to provide a generally smooth finish to the surface of the concrete and to push excess concrete forward as the screed moves along the forms. The winching means is a worm gear dual drum winch powered by a variable speed reversible power drill. A cable sheave is translated along a channel in the frame of the roller screed to effectively lengthen or shorten one of the winching cables to advance one end of the frame faster or slower than the second end of the frame, facilitating movement of the roller screed around curved portions of concrete paving and allowing for angular adjustment of the roller screed for differences that might exist in the winching cables and winching means. The winching means includes a locking mechanism which prevents the roller screed from advancing down a slope. The winch drums are adapted to be selectively disengaged to facilitate rapid advancement of the winching cables. | 09-25-2014 |
