    WILLIAM WHEELER HUBBELL v. THE UNITED STATES.
    [No opinion in C. Cls. R.; 171 U. S. R.]
    
      On the claimant's Appeal.
    
    This was an appeal from a judgment of the Court of Claims dismissing the petition of William Wheeler Hubbell, who, as patentee of an “improvement in cartridges,” claimed that the United States had manufactured and used cartridges covered by his patent under an implied contract to pay a reasonable royalty therefor.
    The Court of Claims had previously decided (20 C. Cls. B.., 354) that there had been no infringement of claimant’s patent, which is the same under which this suit is brought, and that the defendant had used the cartridge prior to claimant’s patent.
    The decision of the court is affirmed, on the ground that the prior decision operated as an estoppel.
    May 31, 1898.
