ABSTRACT:
In accordance with the present invention a power press or tool guard is provided. The guard includes a first generally vertical protective portion which is made of a protective material which is at least partly transparent through which the operator may view the operation of the tool or press; and a second protective portion which depends from the first protective portion and extends inwardly toward the press or tool. The second protective porton includes a plurality of arms or tynes which are pivotably mounted on the lower portion of the first protective portion. The inclination of the arms or tynes on a given side of the guard may be varied by a control member mounted on the first protective portion. In addition the length of individual tynes may be adjusted by loosening fasteners which hold the tynes in place depending from the first protective portion. The guard is pivotable between a first position allowing access to the press or tool for set up, and a second position covering the operating parts to protect the operator when the press or tool is in operation.
