Abstract

A marking paint applicator for a portable electronic locator that locates buried cables and pipes via electromagnetic emissions includes an elongated support structure and a manually moveable trigger mechanism mounted adjacent an upper end of the support structure. At least one bracket assembly is provided for removably connecting the support structure to an antenna mast of the portable locator so that the trigger mechanism will be adjacent a handle of the locator and the trigger mechanism can be squeezed by a finger of an operator'"'"'s hand while grasping the handle. A receptacle is mounted to the support structure for carrying an inverted aerosol paint can and positioning a valve stem of the aerosol paint can for spraying paint onto the ground to mark the location of a buried cable or pipe. An actuating mechanism is capable of selectively deflecting the valve stem to cause the aerosol paint can to spray paint onto the ground to mark the location of a buried cable or pipe. A linkage connects the trigger mechanism to the actuating mechanism for deflecting the valve stem when the trigger mechanism is squeezed.
