Abstract

See full text

An improved safety device or guard for use upon a press or other machine, which has a work zone for receiving a work piece, is provided to protect the operator. The guard has a base with sloped surfaces leading to the work area and slidable gates positioned adjacent said base. The operator inserts the work piece by moving it along the sloped surfaces of the base until it contacts the gates and forces the gates upward. The gates are raised only by an amount which is sufficient to allow the work piece to move into the work zone. The gates ride upon the top of the work piece and automatically adjust for various thicknesses of the work piece during the operation of the machine. The guard has flange members which are attached to the base for slidably mounting the guard to a machine and has a barrier mounted upon the base which is angled inwardly toward the work zone for permitting the use of work pieces which are shorter than the overall width of the barrier.
