In 1858, Messrs. Lough and Messenger, of Swindon, England, designed and erected a steam-road locomotive which for two years ran at fifteen miles an hour on level roads, and six miles an hour up grades of one in twenty. The engine had two cylinders, each three and one-half inches in diameter and with five-inch stroke, working direct on to the crank axle. The driving wheels were three and one-half feet in diameter, and the leading wheels two feet in diameter. The vertical boiler fixed on the frame was worked at one-hundred-and-twenty-pound pressure. The tanks held forty gallons of feed water. The total weight of the locomotive was eight hundred pounds. THOMAS RICKETT When the revival of interest in the common-road steam locomotive began in England, about 1857, Thomas Rickett, of Castle Foundry, Buckingham, was one of the first to give attention to the subject. He built a road locomotive in 1858 for the Marquis of Stafford. This engine had two driving wheels and a steering wheel. The boiler was at the back with the steam cylinders horizontally on each side of it. Three passengers were carried. The carriage was steered by means of a lever connected with the fork of the front wheel. The cylinders were three inches in diameter, with nine-inch stroke; the working steam pressure was one hundred pounds per square inch. The driving wheels were three feet in diameter. The weight of the carriage when fully loaded was only three thousand pounds. On level roads the speed was about twelve miles an hour. An account of one of the trips in 1859 was as follows in the columns of The Engineer: "Lord Stafford and party made another trip with the steam carriage from Buckingham to Wolverton. His lordship drove and steered, and although the roads were very heavy, they were not more than an hour in running the nine miles to Old Wolverton. His lordship has repeatedly said that it is guided with the greatest ease and precision. It was designed by Mr. Rickett to run ten miles an hour. One mile in five minutes has been attained, at which it was perfectly steady, the centre of gravity being not more than two feet from the ground. A few days afterwards this little engine started from Messrs. Hayes' Works, Stoney Stratford, with a party consisting of the Marquis of Stafford, Lord Alfred Paget, and two Hungarian noblemen. They proceeded through the town of Stoney Stratford at a rapid pace, and after a short trip returned to the Wolverton railway station. The trip was in all respects successful, and shows beyond a doubt that steam locomotion for common roads is practicable." Two other engines were built by Rickett, one of them for the Earl of Caithness. Some improvements were installed in this carriage, which was intended to carry three passengers. The weight of the carriage, fully loaded, was five thousand pounds.
