ABSTRACT:
A movable marking apparatus for marking a supporting surface includes a housing member, wheels rotatably mounted to the housing for engaging the supporting surface and rolling on it, and a handle assembly secured to a rear portion of the housing for controlling the apparatus and actuating the nozzle of a spray can. The apparatus also includes a counterweight element mounted on the front of the housing. This counterweight element prevents inadvertent lifting of the front of the apparatus and accordingly minimizes discontinuities and imperfections in the marks which the apparatus provides.
