Abstract: A manually operable curb extrusion device for extruding curb, barrier wall, gutter or the like from concrete, cement or some other moldable building material. The curb extrusion device has rapidly interchangeable extrusion molds and compacting members to provide for quick and efficient changing from one type of curbing to another. The building material is placed in a receiving hopper and falls into a compacting chamber where a power driven and reciprocating compacting member compacts the material into the extrusion mold where it is shaped before extrusion. The curb extrusion device is manually directed or steered along the desired course via an adjustable steering mechanism.
