Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
