Syllabus

<p>1. Patents — Construction of Claims — Reference to Specification.</p> <p>The words, “to operate substantially as described,” at the end of a claim, do not import into the claim elements described in the specification; but not mentioned in the claim, for the purpose of either extending or limiting it.</p> <p>2. Same — Infringement—Electric Railway Trolleys.</p> <p>The Anderson patent, No. 412,155, for improvements in electric railway trolleys, claim 8, which covers the combination with a trolley frame and wheel of metallic conducting brushes between the hubs of the wheel and the frame, “to operate substantially as described,” is not limited to a structure in which the bearings of the wheel are insulated so that the entire current is carried through the brushes, although such a construction is described in the specification, the brushes being operative without such insulation. The claim construed, and held valid and infringed.</p>
