ABSTRACT:
The embodiment of the invention disclosed herein is directed to a curber and sidewalk-forming apparatus for contouring concrete along a predetermined run. The apparatus includes a hopper having at least one wall thereof sloping downwardly toward an opening formed in the bottom of the hopper which coincides with an opening formed in a slide plate surface at the bottom of the machine. Flowable concrete passes from the hopper through the opening in the slide plate and is directed rearwardly of the apparatus while the apparatus is transported in a predetermined direction along its run. A vibrating apparatus is secured to one of the walls of the hopper to insure proper flow of the concrete along the interior surface of the hopper so that the concrete continuously flows beneath the apparatus for forming curbs, gutters and sidewalks. A motor generator set is secured to the slide plate and produces electricity to operate electrical motors of the vibrator and winch secured thereto.
