Syllabus

<p>1. Patents—Infringement—Electric Railway Motors.</p> <p>The Knight patent, No. 354,793, covers a combination of two motors in the same circuit for use on electric railways with a controlling device for each adapted to be operated from a common point. As illustrated in the specification and drawings, such device consists of a small or pilot motor connected with each power motor, controlled by a common switch, and which operate mechanism for shifting the commutator brushes. Claim 2 is limited in terms to such device, but claims 10 and 11 claim broadly the combination of the motors with any controlling device operated from a common point. Held, that such claims were not limited by the specification to a combination in which the controlling device operates by shifting the brushes, and that they were infringed by one in which the controller operated by introducing a rheostat to interrupt and waste the current, instead of reversing it.</p>
