ABSTRACT:
A grit-blasting or liquid-spraying machine in which a nozzle is reciprocated at a substantially constant linear speed in a direction transverse to a primary direction of travel of the machine, thereby providing substantially uniform coverage of a surface to be treated. The nozzle is carried on a transversely movable supporting block which is secured to a sliding nut which, in turn, is engaged on a rotating shaft and reciprocates back and forth with substantially no slowing at the ends of each stroke. In a grit-blasting embodiment of the machine, the nozzle is also angularly oscillated in a direction parallel to the primary direction of travel, to further increase the uniformity of coverage. In a disclosed paint-spraying embodiment, the machine is advanced in the primary direction of travel only during return transverse strokes of the nozzle, when paint flow is temporarily terminated. Multiple paint-spraying or grit-blasting machines can be coupled together for wider surface coverage.
