APPEAL FROM THE CIRCUIT COURT OF THE UNITED
STATES FOR THE EASTERN DISTRICT OF MICHIGAN
A patent for a bushing or tapering ring of metal for the bungs of casks, with a screw thread on its outer surface and with a notched flange at the edge, so as to enable the bushing to be forced into place by a wrench having a projection to fit the notch, was reissued, nearly seven years afterwards, for a bushing without any notch. Held that the reissue was void.
Bill in equity for the infringement of letters patent. Decree dismissing the bill. Complainant appealed. The case is stated in the opinion.
