Post-Graduate of Boston University in 1907, with degree of Doctor of Philosophy; course including Electrical and Mechanical Engineering. OCCUPATION AND WORK DONE: Engaged in developing and practising electrical engineering from prior to 1870 up to the present time (1909). Original inventor and patentee of the automatic electrical and electrically controlled fluid pressure signal systems for railroads now in universal use on the leading railroads in the United States and foreign countries, wherever and by whomsoever installed, throughout the world. 1870. Received four United States patents on this system; applications filed earlier. 1870. Exhibited an elaborate working model of the system at the American Institute in New York, showing the automatic signal system in operation under control of passing cars. 1871-2. Original inventor and patentee of the closed track circuit system of signaling. Received basic United States and French patents covering same, in 1872. Applications filed, 1871. 1870-71. Original inventor and patentee of the automatic electro-pneumatic signal systems for railroads in use for many years past. Received basic British patent covering this system in 1871. So far as I have been able to ascertain on careful investigation, this patent appears to be the first ever issued anywhere on this subject. The following brief historical excerpt is taken from a United States patent granted to me on October 20, 1908, No. 901,383, on an electric railway system. This patent is one of a bunch of eight taken out by me on the same date, on the same subject. The excerpt relates to my work in signaling. "The block signal system herein disclosed is an embodiment of the Robinson electro-pneumatic system now in extensive operation on the Pennsylvania railroad and many other leading railroads in this and other countries, embodying the closed circuit rail system for which a basic U.S. patent was granted to me on August 20, 1872, No. 130,661 (reissued July 7, 1874), the electro-pneumatic signal system disclosed in my British patent of August 30, 1871, No. 2280, the subject matter of both of which patents is disclosed in my French patent of February 29, 1872, No. 94,393. The electro-pneumatic signal system disclosed in the above named patents is also disclosed in my United States patent dated November 7, 1882, No. 267,259. As above indicated the block signal system herein described comprises the system described in my above named patents and now in general use on leading steam railroads, but modified and improved in a way adapting it for reliable and efficient use in connection with electric railroads of the sectional third rail type." The admission of the above brief history in the above described, and substantially in two other patents of the same date, is, of course, a complete verification of its historical accuracy by the Patent Office.
