Summary

Portrait of William Burnham Woods William Burnham Woods McMurray v. Mallory — Opinion of the Court

The contention of the appellants that the soldering-iron of the Tillery & Ewalt patent is merely the disk of the Barker patent with a large part of its circumference removed, defeats itself, for when a large part of the disk is removed it ceases to be a disk, and becomes the mere soldering-iron of the Tillery & Ewalt device; whereas, as we have seen, a disk is an essential element in the invention covered by the Barker patent.

The idea of revolving the soldering-tool about the pivotal rod is not suggested in the original patent, but is excluded by the statement in the specification that the inventor contemplated making the soldering-iron and the guilding-rod of any form in transverse section necessary to fit in any form of cap, whether round, square, oval, or of any other curved or polygonal shape.
