“ Roberts invented the compensating gear that he first used on his steam carriage. This gear superseded claw clutches, friction bands, ratchet-wheels, and other arrangements for obtaining the full power of both the driving-wheels, and at the same time allowing for the engine to turn the sharpest corner. In 1839, Roberts invented an arrangement for communicating power to both driving-wheels at all times, whether turning to the right or left. During the latter years of his life this famous engineer lived in exceedingly straitened circumstances, and he died in poverty. ”

“ In the seventies were also experiments on modified forms of power on vehicle propelling motors other than steam, but it still seemed to be the steam vehicle that characterized the new period of activity which blossomed out in the early eighties with many ardent advocates, and exhibited a type of light vehicle with efficient strong boiler and light engine. America should not be overlooked, however, when we consider the one small vehicle of Austin, which was constructed in Massachusetts, and attracted great attention at the shows of the Ocean Circus, in the early seventies, or thereabout. ”

“ Serpollet is noted in France to-day as the champion of the steam automobile. In 1887, he appeared in Paris with his three-wheeler, two rear drive and one front steering wheel. With its light and safe generator his machine attracted much attention, but its use in the streets of the capital was temporarily prohibited, until the granting to him in 1891 of the first unrestricted license for such use resulted from his initiation of the prefect of police by driving that important personage in the steamer.
His generator, known as the “flash boiler,” has been developed to a high state of perfection. ”

“ He describes his trip as follows: “I may state that such a feat as going over the Ord of Caithness has never before been accomplished by steam, as I believe we rose one thousand feet in about five miles. The Ord is one of the largest and steepest hills in Scotland. The turns in the road are very sharp. All this I got over without trouble. There is, I am confident, no difficulty in driving a steam carriage on a common road. It is cheap, and on a level I got as much as nineteen miles an hour.” ”

“ He was the first to run a steam carriage for hire on a common road, and is still the only person who has ventured in a steam vehicle to traverse the most crowded streets of the metropolis at the busiest periods of the day; he has built a greater number of steam carriages (if not better) than anyone else, and has been thus enabled to try a greater variety of forms of construction, out of which to choose the best. ”

“ An enthusiastic motorist, Sir Charles Dance, of London, in the first third of the ninteenth century did a great deal to encourage the engineers who were inventing steam road vehicles. He was financially interested in several of the companies that were organized to run steam coaches over the common roads. He was the backer of Goldsworthy Gurney, and was also engaged in building for himself. His most famous car was a coach that ran every day from the Strand, London, to Brighton. This was an engine mounted on four wheels with a tall rectangular funnel that narrowed toward the top. ”

“ Evans’ interest in the steam carriage forthwith ceased, but in his writings, published about that time, he remarked: “The time will come when people will travel in stages moved by steam engines from one city to another, almost as fast as birds fly, fifteen or twenty miles an hour. Passing through the air with such velocity, changing the scene in such rapid succession, will be the most rapid exhilarating exercise. ”

“ Some individuals undertook to ridicule the experiment of driving so great a weight on land, because the motion was too slow to be useful. The inventor silenced them by answering that he would make a carriage propelled by steam, for a wager of three thousand dollars, to run upon a level road, against the swiftest horse that could be produced. ”

“ He is best known as an inventor in connection with the automobile industry. Among his inventions are a shaft drive and a beveled gear drive which are now universally used. He originated the idea of placing the operating lever on the steering post and made the first moderate priced automobile in France. He is now the engineer and manager of one of the biggest factories in the world. ”

“ Vehicles are now of the Pullman type, luxurious to the extent of prices ranging into the thirties of thousands of dollars, while on the other hand, thousands of small vehicles, costing between five hundred and one thousand dollars, are annually made and sold.
The steam machine, after being practically succeeded by the gasoline, was again improved by the flash boiler. The main development of this new power was carried on by Serpollet, of France, and later, by Rollin T. White, in the United States, both whom have become most able competitors of manufacturers of machines of other classes. ”

“ When steam was turned into the cylinder, the piston made an outward stroke; a vacuum was then formed, the steam being condensed in a cold water tank placed beneath the cylinders, and the piston was forced back by the pressure of the atmosphere. The piston rods communicated their motion to the driving-axle and wheels through rack rods, which worked toothed wheels placed on the hind axle on both sides of the engine, and the alternate action of the rack rods upon the tooth and ratchet wheels, with which the drums were provided, produced the rotary motion. ”

“ One of his first inventions was for a machine to split hides, that was set up and operated in the establishment of his father. Later in life he established works for himself in Sheffield, and afterwards in Gainsborough. In 1788, he was a resident of Elland, Halifax, and there made a steam carriage that was run by a [Pg 124] three-cylinder inverted engine. Spur-gearing transmitted the driving power from the crank shaft to the axle. His patent was taken out in conjunction with James Ashworth. This vehicle was mounted on two driving wheels and had a smaller steering wheel in front. ”

“ By many he has been considered as having contributed more even than James Watt to the development of the steam engine and its broader adaptation to practical uses. In his early years he was restrained in putting his ideas and experiments to practical test by the restrictions of Watt’s patents. Finally when that difficulty was removed he at once took a leading position in his profession. Especially in the development of the high pressure engine he is entitled to at least as much credit as any man of his day. ”

“ The squires became alarmed lest their horses should take fright; and although a judge ruled that a horse that would not stand the sight or sound of a locomotive, in these days of steam, constituted a public danger, and that its owner should be punished and not the owner of the locomotive, an act was passed providing that no engine should travel more than four miles an hour on the public roads. Thus was the trade in [Pg 162] quick-speed locomotives strangled in its cradle; and the inhabitants of country districts left unprovided with improved facilities for traveling. ”

“ 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. ”

“ The first experiments of David Gordon, who in 1819 was working with William Murdock, in Soho, were for the purpose of using compressed air for common road locomotives. He also invented a portable gas apparatus, and originated a society of gentlemen, with the intention of forming a company for the purpose of running a mail coach and other carriages by means of a high-pressure engine, or of a gas vacuum or pneumatic engine, supplied with portable gas. ”

“ The steam, passing through the cylinder, went into an air condenser. The power of the engines was communicated from the piston rods to the driving wheels of the carriage by sweep rods, the lower ends of which were provided with driving pinions and detents, which operated upon toothed gear fixed to the hind carriage axle. The object of this mechanism was to keep the driving pinions always in gear with the toothed wheels, however the engine and other machinery might vibrate or the wheels be jolted upon uneven ground. ”

“ In 1769, Francis Moore, of London, a linen draper, invented a machine which he described as made of wood, iron, brass, copper, or other metals, and constructed upon peculiar principles, and capable of being wrought or put in motion by fire, water, or air, without being drawn by horses or any other beast or cattle ”

“ On each side of the driving-wheel, ratchet wheels were fixed, and as one of the pistons descended, the piston-rod drew a crank, the pawl of which, working into the ratchet-wheel, caused the driving-wheel to make a quarter of a revolution. By gearing, the same movement placed the piston on the other side in a position for making a stroke, and turned the four-way cock, so as to open the second cylinder to the steam and the first cylinder to the atmosphere. ”

“ These things are required: (1) a rotary motion; (2) easily altering its direction to any other direction; (3) to be accelerated, retarded, destroyed, revived, instantly and easily; (4) the bulk, the weight, the expense of the machine to be as small as possible in proportion to its weight.” Darwin gave sketches and suggested that the steam carriage should have three or four wheels, and be driven by an engine having two cylinders open at the top, and the steam condensed in the bottom of the cylinder, on Newcomen’s principle. ”

“ The petroleum was drawn from a tank, the supply being regulated by the valve. The motor was first set in motion by lighting a lamp and turning the crank a few times, the discharge passing through the chamber into an exhaust-pipe. After the motor had been fully started, the vehicle was set in motion by moving a lever, which drew a tightening pulley against the belt, and so caused the power to be transmitted from the shaft pulley to the wheel pulley. Changes of speed were attained by using pulleys of different sizes, similar to the cone pulleys on a lathe. ”

“ In addition to gas, which is applicable for stationary motors only, the fuel may be benzine of a specific gravity of sixty-eight or seventy one-hundredths, or ordinary lamp petroleum. The consumption varies according to the size of the motor, ranging [Pg 98] from thirty-six to forty-five one-hundredths kilograms per horse-power hour for vehicles, or somewhat less for boats. He adapted these light motors to vehicles of many styles, and his persistent work in this connection has made the world-wide reputation of the Daimler Motoren Gesellschaft, now flourishing at Cannstadt, Germany. ”

“ Then he organized a joint-stock company, the Steam Carriage and Wagon Company, which proposed to construct steam drags in Dublin and in Manchester, which, when completed, were to convey goods and passengers at double the speed and at half the cost of horse carriages.
Anderson said: “I produce and prove my steam drags before I am paid for them, and I keep them in repair; consequently, neither the public nor the company runs any risk. The first steam carriage built for the company is nearly completed. It will speak for itself.” ”

“ Devil, do drive on as fast as you can. Nothing to pay!”
The engine in this carriage had a cylinder five and one-half inches in diameter, with a stroke of two and one-half feet, and with thirty pounds of steam it worked five strokes per minute. In every way it was superior to its predecessor. It was not so heavy; and the horizontal cylinder, instead of the vertical, added very much to its steadiness of motion; while wheels of a larger diameter enabled it the more easily to pass over rough roads which had brought the Camborne one to a standstill. ”

“ Taking up for consideration Hero’s hollow ball filled with water from which steam was generated by the outward application of heat, he added these conclusions: “We have a more sensible effect of the elasticity of vapors if the hole be made bigger and stopped, and then the ball be laid upon the fire till the water boils violently; after this, if the ball be set upon little wheels, so as to move easily upon a horizontal plane, and the hole be opened, the vapors will rush out violently one way, and the wheels and the ball at the same time will be carried the contrary way.” ”

“ The steam carriage built by the Tangye Brothers, of England, about 1852, was a simple affair. It had seating capacity in the body for six or eight persons, while three or four more could be accommodated in front. The driver who sat in front had full control of the stop valve and reversing lever, so that the engine could be stopped or reversed by him as occasion required. The speed of twenty miles an hour could be attained, and the engine with its load easily ascended the steepest gradients. ”

“ The able assistance of William Maybach brought further credit to the company, particularly in view of the aspirating carbureter which, with such details as clutch and transmission mechanism, helped to perfect the Cannstadt automobiles. In the latter nineties the prominence of the Daimler Works as vehicle makers, distinguished from motor makers, again began to be noticed and soon their now famous Mercedes cars appeared. In recent years these machines have made remarkable records in races and all other branches of the sport. ”

“ The steam vehicle for stationary purposes, and also for the locomotive, were being rapidly developed and refined. The railroad settled down to the idea of a power unit drawing numerous wagons. That has been consistently adhered to to the present day, and only in the past decade have we gone back to the old and first principles of embodying the mechanical propelling means in the same vehicle that transports the passengers or goods. ”

“ Aside from Nicholas Joseph Cugnot, the French army officer who, about 1769, constructed an artillery wagon propelled by a high-pressure engine, those who first built successful self-propelled vehicles for highway travel were the famous engineers of England and Scotland, who harnessed steam and developed the high-pressure engine in the last half of the eighteenth century and the first half of the nineteenth. James Watt patented, in 1782, a double-acting engine, which he planned might be “applied to give motion to wheel carriages,” the engine to be portable ”

“ Early in the forties a small road locomotive was made by Goodman, of Southwark, London. It was worked by a pair of direct-acting engines, coupled to the crank shaft. A chain pinion on the crank shaft transmitted motion to the main axle through an endless pitch chain working over a chain wheel of larger diameter on the driving shaft. The smoke from the boiler was conducted by a flue placed beneath the carriage. The vehicle had a speed of from ten to twelve miles an hour. ”

“ He took out other patents and also gave some attention to devising a mechanical carriage propelled by man power. In 1822, he made a vehicle that was moved by a pair of treadles and cranks worked by the driver.
Even the steam engine engaged his attention. Some improvements which he proposed in it are recorded in works on mechanics. While residing at Eltham, in Lincolnshire, he used frequently to tell his son that, if he lived to be a man, he would see both ships and land-carriages impelled by steam. ”

“ But above all things, the great art of railroading had already grown from infant existence to a condition of great possibilities, which were now to be finally determined by a success, not alone mechanical and in the eyes of the inventor, but measured by the balance sheets of the companies of individuals who had made possible the construction of the various experimental locomotives or experimental lines then being operated in England and elsewhere. Just at [Pg 19] this time, in the thirties of the nineteenth century, seems to have been the crucial point. ”

“ His patent for a water-tube boiler for road locomotives was secured in 1823, and his first car was built in 1824. This was a twenty-passenger steam coach. Each rear wheel had a double-cylinder engine, and the pistons were worked at a pressure of two hundred pounds per square inch. Separate engines to each driver gave each wheel an independent motion, so that power and speed might be varied for turning corners, the outer wheel travelling over a much greater space than the inner wheel. ”

“ Howell, a writer of the period, thus quaintly described the Stevin carriage: “This engine, that hath wheels and sails, will hold above [Pg 110] twenty people, and goes with the wind, being drawn or moved by nothing else, and will run, the wind being good and the sails hois’d up, about fifteen miles an hour upon the even hard sands.” ”

“ Instead of using the uncertain-acting flame with the inconvenient speed limitations, Daimler invented and introduced in 1883 the so-called hot-tube ignition. This consisted of a metal or porcelain tube attached to the compression space of the cylinder in such a manner that the interior of the tube was in continual communication with the compression space. A gas flame, continually burning under the tube, maintained it at a glowing red heat, so that the mixed charge of air and gas, when compressed into the tube, became fully and effectively ignited. ”

“ But Murdock was too useful a man to Boulton & Watt to be allowed to have free rein, and his inclination toward steam locomotion invention was apparently curbed, though it would appear Watt thought the roads of that time an insurmountable obstacle to the development of road vehicles, and wanted Murdock to devote his time to mechanical matters more ripe for success. Boulton, writing to Watt from Truro, in September, 1796, tells how he met Murdock on his way to London to get a patent on a new model, and how he persuaded him to turn back. ”
