Title: Retracting guard for grinding wheel - has fixed and moving halves, moving half swings back when wheel rotates
IPC: B24B55/05
Filed: 1975-06-12
Abstract: The auto-retracting guard portable grinding tool on an electric or pneumatic is a two-piece (4, 6) flanged disc. The disc flanges return to cover the working periphery of the grinding wheel (3). Each disc guard covers 180 deg. of the periphery of the grinding wheel. When the wheel starts to rotate the retractable half (6) of the disc guard rotates 180 deg. to be housed within the static guard (4). The retractable guard (6) may be attached to a rotatable plate (7) in turn mounted on the nose (5) of the tool.
