Abstract
A construction material marking device includes an edge rail. A marking arm extends laterally from the edge rail. A marker mount is disposed upon the marking arm for mounting a marker, such as an aerosol paint container. A mark discharge assembly is mechanically connected to the roller. Rotation of the roller causes the mark discharge assembly to activate the marker at periodic intervals during rotation of the roller. Activation of the marker may propel an aerosol spray through an aperture of the marking arm for placement of marks at predetermined intervals on a construction material. Marks may correspond to fastener positions that are offset from the construction material's edge and longitudinally spaced apart at an interval corresponding to a building code.
Claims16
A construction material marking device comprising:
- an edge rail that is straight and extends longitudinally to ride in contact with a straight edge of a construction material;
- a marking arm that adjustably extends laterally from the edge rail which slidably receives the marking arm;
- a marker mount disposed fixedly upon the marking arm at a distal end, the marker mount structured to hold a marker;
- a roller mounted to the marking arm, wherein the roller rotates about an axis perpendicular to the edge rail;
- a mark discharge assembly mechanically connected to the roller, wherein the mark discharge assembly comprises:
- a camshaft mounted to the roller and disposed through a housing of the marker mount, the camshaft structured to move a nozzle of the marker from an inactive position to an activated position;
- and
- wherein the mark discharge assembly is configured to activate the marker held by the marker mount to dispense a marking material at predetermined intervals in an interrupted marking line that is laterally offset and parallel with the edge rail;
- and
- wherein positionally adjusting the marking arm perpendicular to the edge rail establishes a lateral offset of the marker mount.

- a mark discharge assembly mechanically connected to the roller, wherein the mark discharge assembly comprises:
- a slider-crank linkage comprising:
- a connecting rod connected to the roller;
- and
- a trigger arm disposed distal to the connecting rod, wherein the trigger arm is operable to move past a first limit position, in a first direction, to engage the marker and move past the first limit position, in a second direction, to disengage the marker;
- and
- wherein the mark discharge assembly is configured to activate the marker held by the marker mount to dispense a marking material at predetermined intervals in an interrupted marking line that is laterally offset and parallel with the edge rail;
- and
- wherein positionally adjusting the marking arm perpendicular to the edge rail establishes a lateral offset of the marker mount.
