said nozzle adapter angle head comprising a substantially rectangular polyhedron-shaped member having a channel formed within its body for flow of paint therethrough and an integrally constructed, rearwardly extending nozzle adapter angle head extension defining the bottom half portion of said nozzle adapter angle head, said nozzle adapter angle head extension having a substantially flat top wall and a substantially arcuate rear wall to facilitate rotatable cooperation with said pole angle head, said nozzle adapter angle head extension including a transverse threaded opening formed therein to facilitate attachment of nozzle adapter angle head and pole angle head, said threaded opening including an annular recess adjacent the top wall and bottom wall of nozzle adapter angle head extension for receipt of nozzle adapter angle head sealing means to facilitate sealingly engagement of angle head bolt, said threaded opening including one or a plurality of ports which communicate with said nozzle adapter angle head channel, said nozzle adapter angle head having a front wall including integrally constructed nozzle adapter means extends forwardly from said front wall having its outer surface threaded for threadedly attachment with said spray nozzle, said nozzle adapter means having an axially extending opening formed therein which communicates with said paint channel formed within the body of said nozzle adapter angle head;

said angle head bolt being formed having circumferentially extending lower recess adjacent bolt head, lower threaded portion adjacent said lower recess, circumferentially extending upper recess adjacent said lower threaded portion, and upper threaded portion adjacent said upper recess, said angle head bolt having an axially extending bolt channel whereby paint is permitted to flow from pole angle head to said nozzle adapter angle head by means of transverse ports formed in said upper bolt recess and said lower bolt recess, said upper bolt port being in communication with ports formed in the threaded opening in pole angle head extension, said lower bolt port being in communication with ports formed in the threaded opening in said nozzle adapter angle head extension.

2. A surface marking device as described in claim 1, including nozzle gasket sealing means provided to facilitate sealingly attachment of said paint spray nozzle and said nozzle adapter angle head, wherein said paint spray nozzle is an integrally constructed member including at its upper end nozzle torque-receiving means and at its lower end a nozzle tip, said nozzle torque-receiving means and nozzle tip being joined by means of integrally constructed tip support base formed thereinbetween, said nozzle torque-receiving means having its inner wall threaded complimentarily with threads of nozzle adapter means, said nozzle tip comprising a pair of outwardly disposed nozzle blades having interior walls which extend to tip support base bottom wall, said tip support base bottom wall having a concavely recessed channel formed between said nozzle blades including a spray nozzle paint ejection port formed in said bottom wall channel, said nozzle blades permitting delivery of a trapezoidal paint spray upon the surface to provide a guide line or stripe of consistent width when nozzle tip is positioned with tip support base bottom wall in substantially parallel alignment with the surface to be marked.

3. A surface marking device adapted to mark a guide line or stripe upon the surface of a road or pavement for installation of parking lines and traffic markings, comprising in combination, airless paint spray power system, airless paint spray mechanism, and wheel-mounted paint spray mechanism support carrier;
