This is an appeal from a decree adjudging that appellant’s patent, No. 940,300, November 16, 1900, for a safety deposit box lock, was not infringed by the locks used by appellee. In our judgment the two locks, as fully described and explained in Judge Sanborn’s opinion in 212 Fed. 178, differ so radically in their structural laws that the case was properly disposed of by the finding of noninfringement. The decree is affirmed.
