Abstract: A carriage having a paint nozzle and reflective bead nozzle is provided for rolling along a roadside barrier, such as a guard rail or Jersey wall, to apply a reflective paint stripe on the barrier to improve visibility of the barrier at night. The carriage includes a first set of wheels to support the carriage on an upper edge of the barrier, and one or more additional sets of wheels to maintain proper spacing between the nozzles and the barrier surface being painted. The carriage includes handles with controls for actuating the nozzles. The paint and bead nozzles are connected to the paint system and pressurized bead tank on a paint striper, which may move simultaneously with the carriage along the barrier during the painting process.

Abstract: An electronic control system is provided for moving one or more paint carriages on a paint striping vehicle. The control system includes an electronic steering module, an electronic control module, a linear positioning transducer for each carriage, and a hydraulic control valve for each carriage. The steering module includes a rotatable wheel for extending and retracting the paint carriage without lost motion. A power switch and an emergency stop switch are provided for the system.

Abstract: A zero velocity bead dispenser is provided for a paint striping vehicle. The dispenser includes an electric motor which rotates a pair of rollers. A bead gun directs reflective particles into the nip point between the rollers, which discharge the particles or beads with a rearward velocity substantially matching the forward velocity of the vehicle. Therefore, the beads are discharged into the wet paint on the road with a net zero velocity so as to minimize or eliminate rolling of the beads in the paint, thereby maximizing the reflective properties of the beads. A speed sensor continuously monitors the vehicle speed and automatically adjusts the motor speed, and thus the roller speed, so as to maintain the relative zero velocity of the discharged beads.
