Abstract
A sealed chuck assembly having a hollow cylindrical chuck body including a radially disposed front wall and a plurality of master jaws supported on the chuck body to move radially within openings in the front wall and relative to the chuck body in response to operation of a jaw actuating mechanism contained within the chuck body. A canopy plate attached to the chuck body overlies the front wall and has apertures therethrough in general registry with the openings. The master jaws are exposed within the apertures to facilitate attachment of a top jaw to each master jaw. Annular sealing members disposed between the rear surface of the canopy plate and forwardly facing surfaces on the master jaws seal each of the openings in all positions of the master jaws relative to the chuck body. Top jaws may be secured to and removed from the master jaws without disturbing the sealing members so that the openings in the front wall of the chuck body remain in sealed condition at all times.

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.
