L. HAND, Circuit Judge.
We see no reason to consider the validity of the patent, which for the purposes of this case we shall assume. The case turns merely upon infringement and is in two parts: First, whether the defendant has "a coiled bead at the lower edge of the flange, said bead being collapsed at intervals," as provided in claims 2 and 4, between which we make no distinction; second, whether it has a "bead flattened at intervals," as provided in claim 9.
