Nikola Tesla U.S. Patent 511,916 - Electric Generator Patent Wrapper Page 30

J 1 1 It is entirely clear that Jablochkoff intended by his drawing only an ordinary engine, and omitted the valve controlling and regulating mechanism merely because they would be superfluous in such an illustration and unnecessarily complicate the drawing. His specification contains no indication what ever of a different purpose although it may be that the examiner has attached to a clause which it contains a significance which the context does not warrant. We refer to the clause "The apparatus once brought into normal operation (La machine une fois mise en train) continues to run by virtue of the conversion of the impelling force into electricity. of the sugine non of the system This however, refers not to the operation as a whole, but only to the excitation (amorcer) of the field of the generator, as is evident from the sentence immediately preceding. We believe that applicant's invention will mark a distinct epoch in electrical engineering and it is incanceivable that its results should have been appreciated much less realized as long ago as 1876, and it seems to us that the vague and in complete information obtainable from the Jablochkoff patent should in no way stand in the way of the claims now presented. We have considered the reference practically as bearing on claim 1, but the other claims seem to us as entirely free from the abjection made. Reconsideration is asked. Respectfully, Drucean & Page Inserla. 37
