Abstract
Abstract A shield assembly to be positioned between a work area of a machine tool and an operator station is characterized by a unitary, generally U-shaped transparent sheet of a durable polymer having a planar front center portion and side legs diverging therefrom. One of the side legs is equipped with a handle and is secured to one end of a universal support arm, the other end of which is mountable to the machine remote from the work area. The handle and universal arm enable the shield to be quickly and positively moved between positions adjacent and remote from the work area. When adjacent, the center portion of the shield extends across the front of the work area and the side legs extend rearwardly across opposite sides thereof to form an effective barrier to the passage therepast of chips, broken tools, coolant, etc., ejected from the work area.
