Shield unit for machine tool

A shield unit for a machine tool which has a threaded spindle adjustment rod, and a cutting member, the machine tool being adapted to be operated by an operator who is adjacent the cutting member, the threaded spindle adjustment rod having a given diameter and having threads of a given size and spacing, comprising an elongate stem, a clamp, means attaching the clamp to the elongate stem, the clamp being provided with a pair of relatively movable portions, each of the movable portions having an arcuate threaded surface, the arcuate threaded surface being complementary to the curvature of the threaded rod and the threads thereof, the movable portions of the clamp being movable to place the arcuate threaded surfaces in juxtaposition, whereby a threaded opening is established in which the threaded opening has a diameter substantially equal to the diameter of the threaded spindle adjustment rod, the movable portions being movable to engage and encompass the threaded spindle adjustment rod of the machine tool, to attach the clamp to the threaded spindle adjustment rod, a transparent sheet, means attaching the transparent sheet to the elongate stem, whereby the clamp when attached to the threaded spindle adjustment rod maintains the stem and the transparent sheet in a position adjacent the cutting member for protection of an operator of the machine tool.

A shield unti for attachment to a machine tool which is provided with a cutting member and in which an operator of the machine tool is positioned adjacent the cutting member as the cutting member cuts a work piece, the machine tool also being provided with a threaded rod, comprising a clamp, the clamp having a plurality of clamp parts, each of the clamp parts being movable, each of the clamp parts having an arcuate clamp portion, the arcuate clamp portion of at least one of the clamp parts having a threaded surface, the clamp parts being relatively movable to threadedly clampingly attach the clamp to the threaded rod and to release and to remove the clamp from the threaded rod, an elongate stem, means attaching the elongate stem to the clamp, a rigid transparent sheet, and means attaching the rigid transparent sheet to the elongate stem, whereby the clamp, including each clamp part having a threaded surface, is threadedly clampingly attached to the threaded rod, and the rigid transparent sheet is positioned adjacent the cutting member and between the cutting member and an operator of the machine tool as the rigid transparent sheet serves as a shield to protect the operator of the machine tool.
