Ravel, of France, planned in 1868 a steam vehicle, and about 1870 completed the construction of one at the barracks at Saint-Owen. Then came the declaration of war with Prussia, and the barracks, being within the zone of fortification, the vehicle was lost or destroyed. There is no certainty that it was ever unearthed after peace was declared. L. T. PYOTT Before 1876, a motor vehicle was invented by L. T. Pyott, who was then a foreman with the Baldwin Locomotive Works in Philadelphia. The carriage, which could carry seven persons at the rate of twenty miles an hour, cost about two thousand two hundred dollars, and weighed nearly two tons. It was shown at the Centennial Exposition in Philadelphia in 1876, but was not allowed to run on the streets. A. RICHTER An engineer and mechanician of Neider-Bielan, Oberlaneitz, Germany, Richter secured in 1877 a patent for a vehicle that was propelled by a motor consisting of a stack or battery of elliptic springs horizontally disposed, which were compressed by a charge of powerful powder exploded in what was practically a cannon. The subsequent expansion transmitted the driving effort to the wheels by a rack of gears. The success of this vehicle is not generally known. RAFFARD In 1881, Raffard, a French engineer, made a tricycle and a tram-car that is said to have been the first electric automobile which ran satisfactorily. CHARLES JEANTEAUD It is claimed for Jeanteaud that he built a four-wheeled electric vehicle about 1881, which was changed in 1887 by the addition of an Immisch motor. In 1890 he constructed a three-wheeled steam vehicle for five persons, having the advice and interest of Archdeacon. In June, 1895, at the Paris-Bordeaux race, he entered an electric automobile and established battery relays every twenty-five kilometers, but without success so far as speed was involved in comparison with the gasoline cars. In 1897 he constructed a gasoline phaeton, but his subsequent work has been primarily confined to the electric. SYLVESTER HAYWOOD ROPER As early as 1850, Sylvester Haywood Roper, of Roxbury, Mass., began experimenting with steam for street-vehicle propulsion. In 1882, when he was seventy-three years of age, he fitted a Columbia bicycle with a miniature engine, and with this he could run seventy miles on one charge of fuel. His bicycle weighed one hundred and sixty-five pounds. He engaged in many track events and his record for three runs of one-third of a mile each, was forty-two, thirty-nine and thirty-seven seconds. COPELAND A tandem tricycle with a vertical boiler and a two-cylinder vertical engine was built by Copeland, of Philadelphia, in 1882. Kerosene was used to fire the boiler. It is said that over two hundred of these machines were built. G. BOUTON
