摘要： In accordance with this invention I provide a curb laying machine designed to extrude curbing of molten asphalt or concrete in a parking lot or the like. This machine utilizes a wheeled chassis, and a curb mold removably carried on a lower portion of the chassis, with the lower edges of the mold in contact with the ground during the laying of curbing. An engine driven auger is utilized for bringing about the extrusion of curbing through the curb mold as the machine moves slowly forward. My machine utilizes a chassis, steerable front wheels supporting a forward portion of the chassis, and first and second rear wheels mounted on a rearward portion of the chassis. The improvement in accordance with my invention comprises a rapidly operable height changing mechanism associated with the first rear wheel, latter wheel being located in the immediate vicinity of the curb mold. This first wheel is disposed upon a pivoted framework mounted on a lower portion of the chassis, and also provided is an extensible fluidic actuator under control of the operator of the machine. This extensible fluidic actuator is operatively connected to the pivoted framework, and serving, when caused by the machine operator to extend, to rapidly bring about a degree of lifting of the rear portion of the chassis, thus to remove the lower edges of the curb mold from ground contact, and thereby enabling the operator to turn or move the machine to a new operative position.
