ABSTRACT:
The invention relates to a guard for protecting a drilling machine operator from a drill bit mounted in a vertical drilling machine. The guard comprises a multi-part shield which when operative at least substantially surrounds the drill bit, a tubular protecting member adapted to be attached to the quill of the drilling machine and extending downwardly beneath the quill and within the shield, and means for connecting the shield to the protecting member whereby the shield is suspended therefrom, the shield extending upwardly to a height at least equal to the lower end of the protecting member, and at least one part of the shield being movable between its operative position and an inoperative position which allows access to the drill bit. The protecting member is preferably a split ring which is clamped around the quill and the shield is preferably formed of two half-shields of transparent plastics material attached by a slide to the protecting member.
