ABSTRACT:
A marking apparatus is equipped with a measuring device so that the marking apparatus can make a series of equally spaced marks. The marking apparatus includes an elongated can holder which is adapted to hold an aerosol can of marking material and a trigger for opening the valve of the can to spray the marking material on a surface. The measuring device comprises an elongated rod which is provided with a longitudinally extending slot, and the rod is pivotally and slidably connected to the can holder by a pin or bolt which extends through the slot and a wing nut which is threadedly engaged with the pin. The rod is pivotable between a storage position in which it extends alongside the can holder and a measuring position in which it extends angularly away from the can holder toward the surface. The rod can be releasably locked in either position by tightening the wing nut, and the distance between the end of the rod and the wing nut can be varied by sliding the slotted rod relative to the wing nut. A series of equally spaced marks can be made by placing the end of the rod over the previous mark to space the can holder and spray can a constant distance from the mark.
