Patent attributes
A hand-controlled, curb forming machine that is transformable between different widths and geometries, and between different wheel configurations, to accommodate different concrete curbing. A downwardly projecting, rotating head that rotates about an axis perpendicular to the slab shapes raw concrete into appropriately styled and contoured curbs. A machine frame slidably receives an adjustable, wheeled subframe. A roller on the opposite frame side rides on an opposite curb form. A pivoted handle is reversible. The electric motor is adjustably secured to the frame by a mounting plate movable within follower slots in the frame. A removable adaptor plate disposed on an opposite frame end supports the machine when not in use, but can be removed for normal curb work exposing a form riding roller. When the machine is deployed with monolithic curbs without rebar, the adaptor plate can mount to the subframe to raise the machine by lowering the wheels.
