Abstract: An easily removable safety guard for application to the barrel of a vertical drilling machine so as to overlie the drill bit comprises a coaxially arranged telescopingly connected, guard body and guard sleeve. The guard body is yieldably and resiliently retained in a mounting ring which is in turn clamped on the barrel of the drilling machine. The guard sleeve, or skirt, depends from the guard body to engage at its underside the workpiece or machine bed plate. The guard body moves progressively downwardly relative to the sleeve during progressive downward motion of the barrel. The sleeve is provided with clear-view panels therein and the guard body includes breaker bars to break off slivers of metal cut from the workpiece. Spring pressed ball catches enable the guard body with its sleeve, to be readily removed from the mounting ring with a downward extraction force.

Abstract: A guard for a milling machine comprises a combination of rods and blocks for supporting guard panels relative to the milling tool to provide for an adjustment of the panels relative to the tool axially of such tool. A plurality of mounting bars extend away from the tool area in a plane, each supporting one of a set of mounting blocks. A pair of support rods extend in that plane each from an opposite side of a mounting block, and each transverse to its mounting bar. A pair of support blocks each support one of a pair of guard panels.
