Abstract
A radial saw with safety guards and barriers for rip cutting and cross cutting of workpieces is disclosed. The radial saw includes a motor driven saw blade that is mounted on the supporting arm which overhangs a worktable. The motor driven saw blade is movable relative to a worktable mounted rip fence to enable the motor driven saw blade to be operated for rip cutting workpieces longitudinally along the length of the rip fence and for cross cutting workpieces transverse to the rip fence. An upper blade guard is mounted in fixed position relative to a yoke depending from the supporting arm for covering approximately an upper half of the motor driven saw blade. A lower blade guard depends from the upper blade guard and substantially covers approximately the lower half of the motor driven saw blade when resting on the worktable. The lower blade guard is mounted to the upper blade guard for automatic upward and downward movement relative to the upper blade guard when resting upon workpieces of different thickness to protect the user against contact with the motor driven saw blade. The lower blade guard protects a user against contact with the side of the motor driven saw blade when set up for cross cutting and also against contact against the leading edge of the motor driven saw blade when set up for cross cutting. During rip cutting, the lower blade guard protects against contact at an outfeed end, through the use of a wrong way feed barrier associated with the lower blade guard.
