A steam engine was patented, in 1814, by Thomas Tindall, of Scarborough. The inventor proposed to use this for an infinitude of purposes, such as driving carriages for the conveyance of passengers, ploughing land, mowing grass and corn, or working thrashing machines. The carriage had three wheels--one for steering. The steam engine drove, by spur gearing, four legs, which, pushing against the ground, moved the carriage. The engine could also be made to act upon the two hind wheels for ascending hills, or for drawing heavy loads. A windmill, driven partly by the action of the wind, and partly by the exhaust steam from the engine, was used as adjunct power. JOHN BAYNES A very ingenious modification of William Brunton's mechanical traveler, was the subject of a patent granted to John Baynes, a cutler, of Sheffield, England, in September, 1819. The mechanism was designed to be attached to carriages for the purpose of giving them motion by means of manual labor, or by other suitable power, and consisted of a peculiar combination of levers and rods. The patentee also stated that there might be several sets of the machinery above described for working each set with a treadle, or even only one set and treadle. Then he added: "I prefer two for ordinary purposes, particularly when only a single person is intended to be conveyed in the carriage, who may work the same by placing one foot on each treadle, in which the action will be alternate. The lower parts of the leg should be so formed or shod as not to slip upon the ground. This machinery may be variously applied to carriages, according to circumstances, so as that the treadles may be worked either behind or before the carriage, still producing a forward motion; in some cases it may be advantageous to joint the front end of the treadles to the carriage and press the feet on the hind ends." JULIUS GRIFFITHS Among those who came to the front with plans for steam carriages for the public highways, soon after the roads began to be improved, was Julius Griffiths, of Brompton Crescent. In 1821, he patented a steam carriage that was built by Joseph Bramhah, a celebrated engineer and manufacturer. It is said that part of the mechanism was designed by Arzberger, a foreigner. The carriage has been termed by some English authorities "the first steam coach constructed in this country, expressly for the conveyance of passengers on common roads." It was repeatedly tested during a period of three or four years, but failed on account of boiler deficiencies. Alexander Gordon said of it: "The engines, pumps, and connections were all in the best style of mechanical execution, and had Mr. Griffiths' boiler been of such a kind as to generate regularly the required quantity of steam, a perfect steam carriage must have been the consequence." The carriage moved easily and answered very readily to guidance. The vehicle was a double coach and could carry eight passengers.
