23 F. Cas. 721 | U.S. Circuit Court for the District of Southern New York | 1847
held; [That the specification of the patent to plaintiffs (re-issued March 16, 1846) claims as the invention a combination of arrangement of the parts of machinery described, by which pipe, with the operation of hydraulic pressure, is made with lead in a set or semifluid state. 'That the machine used by the defendants is in substance the same as plaintiffs. That the patentees can legally take out the re-issued patent for more than is described in the surrendered one, if it does not exceed the actual discovery when the first was taken out. That the evidence satisfactorily establishes that the Hansons were the first and original discoverers of the combination of arrangement embraced in the patent.]
