Patent ID: 6984089

Claim:
In a slip-form paver apparatus comprising a frame supported on a steerable transport assembly and a pavement forming assembly having an essentially horizontal finishing pan disposed on the frame for distributing and forming a paving material along a ground surface, a side plate system comprising: a side plate disposed generally vertically in perpendicular relation to and in contact with the finishing pan and having a forming surface on an inward side thereof for slip-forming a substantially vertical side of the paved surface; a vertically-directed extendable and retractible tube assembly connected between the side plate and the pavement forming assembly for adjusting a vertical disposition of the side plate; a set screw device for adjusting an angular disposition of the tube assembly within a range of batter angles of the side plate relative to the finishing pan; and a thumbscrew device connected between the side plate and the frame for closing any gap created between the side plate and the finishing pan and thereby to form a seal therebetween when the side plate is set at the non-perpendicular batter angle.
