Syllabus

<p>1. Patents—Infringement—Box-Nailing Machine.</p> <p>The Smith & Doig patent, No. 342,268, for a box-nailing machine, was not anticipated and is valid, but is so limited in scope by the prior art, as disclosed by the Swan patent, No. 180,503, and others, that the doctrine of equivalents cannot be invoked in its support as against the device of a patent subsequently granted, and therefore presumptively different. Claims 5 and 6, as so limited, construed, and held not infringed.</p>
