ABSTRACT:
An improved shielding against splash of rearward-ejected slurry and dust provides a circular-saw brick-sawing container with a broad shield having a front edge overlapping the saw shroud, and in turn having a rear edge overlapped by a fixed horizontal shield connected with an upright fixed shield spaced from the saw container backsplash. A "Z"-shaped member resiliently connects the broad shield with the saw arm permitting a close, moving overlap at the aforementioned rear edge overlapped by the fixed horizontal shield. Laterally spaced vertical fixed-shields respectively adjacent an angled end of the broad shield splash container at the sides and a half-moon shaped array of spray nozzles wet down dust of dry sawing, controlled by a three-way valve that also controls a saw-wetting spray, both with recirculated, screened water froma catch pan base.
