Abstract
The drive cylinder component of a hydraulic press is reciprocable relative to a fixed ram to drive the press slide toward the press bed for the performance of work on a workpiece between the slide and bed. The cylinder component is provided with an integral radially outwardly extending flange about the periphery thereof at the open end of the cylinder, and the press frame is provided with a stop plate surrounding the cylinder and disposed in the path of the flange so as to be engaged thereby as the cylinder approaches its lowermost position with respect to the press bed. The stop plate and flange are adapted to take a full press tonnage load. The flange also supports guide components engaging gibbing on the press frame for guidance and support of the cylinder and thus the slide during reciprocation thereof.

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.
