Abstract
Abstract The disclosed embodiment of the present invention is a paving machine slip form which generally includes a primary plate for shaping a curb and a sidewalk, a primary blade mounted at the leading end of the primary plate, a finishing plate mounted at the trailing end of the primary plate, and a secondary blade mounted between the primary plate and the finishing plate. The primary plate and finishing plate are supported substantially horizontally to ride over and smooth the exposed surfaces of wet concrete which has been deposited on the ground. Each of the primary and secondary blades are mounted for pivotal movement and a respective hydraulic ram is provided for moving each of such blades to a position to restrict the amount and reduce the thickness of the concrete passing under the primary and finishing plates. In addition, the finishing plate is pivotally mounted and a hydraulic ram is provided for moving it into a position to smooth the upper surface of the concrete layer of reduced thickness. More particularly, the primary and secondary blades and the finishing plate are each selectively movable from a position in which a lower edge or surface thereof is at approximately sidewalk level to a position in which the lower edge or surface thereof extends from approximately sidewalk level to approximately street level.
