Syllabus

<p>Patents ; Patentability.</p> <p>1. A new combination and arrangement of elements productive of a new and useful result was held to be shown in an application for a patent for an improvement relating to engine starters, consisting of a device involving a single unit system in which the dynamo is used as a starting motor and also as a generator for recharging the battery, whore the result accomplished by the applicant is shown to be the displacement of the admittedly complicated and- inherently defective overrunning clutch of the prior art, in a single unit system, by a belt drive, so arranged that when the motor gear connections are made and the dynamo energized to start the engine, the belt connection slips or yields, and when the engine drives the motor the gear connections are out of mesh and the belt enables the engine to drive the dynamo as a generator; and it was further held, that such invention was not anticipated by a yielding belt drive as applied to a generator in a two unit system.</p> <p>2. A doubt as to the patentability of an article will be resolved in favor of the applicant. (Following Re Thomson, 26 App. D. C. 419; Re Eastwood, 33 App. D. C. 291; Re Earbeck, 39 App. D. 0. 556.)</p>
