Monowheels: The Weirdest Transport Known to Man

"QUANTUM SHOT" #467 link Our "Future Tech" contributing writer Paul Schilperoord, whose recent book on "exciting innovations in transportation" you can order here, showcases today the various mono-wheel ideas, covering their development till the 1930s - modern ones will be featured in Part 2.

How would you like to spend your hours in traffic caged inside a giant wheel? Maybe this is why these vehicles never caught on as serious transportation, but the bizarre concept of the monowheel has captivated engineers for almost a century and a half.

Engineers were still widely experimenting with Velocipedes and bicycles, tricycles and quadricycles powered by pedals, treadles or hand-cranks. It was in that wacky time that the idea of the even wackier monowheel was born; a vehicle with one large wheel with the rider and drive-system inside its circumference. Rousseau of Marseilles wheel; right - The Jackson Monowheel: both are from 1869 Just like other human-powered road vehicles of the time, early monowheels are powered either by pedals with a friction-transmission onto the outer wheel or hand-cranks directly connected to the wheel axle. There was also one idea of a horse-drawn monowheel: But who was first? Patent research shows there was some pretty fierce rivalry going on. Georg Bergner from Washington, Missouri managed to get to the patent office with his ‘Monocycle’ design just hours before Allen Greene and Elisha Dyer from Providence, Rhode Island showed up with theirs on that summer’s day of June 22, 1869. And there was even a third American monowheel patented that year by Richard C. Hemmings from New Haven, Connecticut. All three of these monowheels are hand-cranked, only the Greene & Dryer patent has a number of bulging wheel spokes which make it quite an acrobatic manoeuvre to get into the contraption, while two support struts stop it from falling over. That year also saw the introduction of two further pedal-driven monowheels in France, followed by several similar machines in the 1880s and 1890s. The Greene & Dyer Monowheel: 1869 Lewis Harper, unknown date for this concept; right - wheel by Richard Hemmings, 1869 Become your own gerbil Now you need just one good look at a monowheel to spot some of the dangers involved: keeping the damned thing in balance is difficult enough, not to mention the danger of rotating along inside the wheel during quick acceleration or braking. The latter effect is also known as ‘gerbling’, but was not a serious problem until the motorization of the monowheel. So no, in case you are wondering, neither the introduction of the highly sensible Safety Bicycle – characterized by having two wheels of identical, or nearly identical size and a chain-driven rear wheel – or the motorcycle in the mid-1880s stopped monowheel inventors: M. Gauthier's wheel, 1881; right - Harper's monowheel: around 1892. The first motorized monowheel Although the motorcycle had already been invented in 1885, it took another two decades for the first inventor to fit an engine to a monowheel. The first motorized monowheel seems to be the Italian Garavaglia machine, shown at the Milan Exposition by the House of Garavaglia in 1904. The driver in the photograph sits relaxed in his stool with the steering wheel in his hand, but the whole display seems to be balanced by a smaller stabiliser wheel on the side. A second, slightly better design for motorized monowheel appeared in France made by Erich Edison-Puton in 1910 and powered by a 150 cc single-cylinder De Dion engine of 3.5 hp. Here the driver sits inside the wheel more like the position on a normal motorcycle. Garavaglia Machine, 1904; right - Erich Edison-Puton in 1910 A propeller-driven monowheel As if the concept of the (motorized) monowheel itself was not dangerous enough, American inventor Clinton T. Coates got the ‘brilliant’ idea of fitting propeller-drive to one. His design, patented in 1911, features a monowheel with a push propeller at the back. The advantage of this arrangement, however, is that the propeller always pulls or pushes the wheel forwards, without relying on the weight of the rider and engine to provide reaction. There is therefore no possibility of gerbilling due to incautious acceleration, but it could still happen during braking. The D'Harlingue Monowheel, 1917; right top - Popular Mechanics 1914; right bottom - The Coates Monowheel, 1912 Within the next few years, Alfred E. D’Harlingue – also from St. Louis – actually built a propeller-driven monowheel, which appeared on the cover of Popular Mechanics magazine in 1914. His design, however, features a front-propeller fitted directly onto the engine that can be swivelled for steering. The engine steering mechanism is fitted onto a backbone chassis running to a contra weight at the back. The driver sits quite high from the ground and almost upright with the tubular chassis running between his legs. "Gerbilling" is counter-effected by two small wheels at the back and two spikes at the front, which also protect the propeller blade, but seem more like a recipe for disaster than a safety measure should the entire apparatus rotate forward at high speed and the spikes bore themselves into the ground. In 1915 D’Harlingue also patented a propeller-driven monowheel with the engine in the centre of the wheel, driving a front-mounted propeller via chain-drive and the driver sitting on a seat behind and outside of the large wheel. A New Terror of the Road “A New Terror of the Road”, headlined the February 1923 issue of Everyday Science & Radio News. No, this was not a reference to the propeller-driven machine by D’Harlingue: on the front cover was a monstrous monowheel creation by a Professor E.J. Christie of Marion, Ohio. According to the article, this machine had a centre wheel with a diameter of 14 feet with smaller ‘gyro wheels’ on either side weighing some 500 pounds each. The centre wheel was powered by a 250 hp airplane engine, which Christie hoped would give this “Mother of all monowheels” a top speed between 250 and 400 kph. Although the front cover of Popular Science Monthly from April 1923 depicted it on a racing track, we have no idea what ever happened to Professor Christie. on the right - "Everyday Science & Radio News" for Feb 1923 Across Europe on a Monowheel! The 1920s, however, also saw the introduction of a few more ‘sensible’ motorized monowheels, which were really aimed as useable one-wheeled motorcycles. One of these was the mid-1920s Italian Motorouta that was actually produced in limited numbers. According to an advertisement of the time this machine had a 175 cc engine coupled to a 3-speed gearbox. It must have worked reasonably well, since a Swiss engineer by the name of Gerdes set of with a Motorouta machine for a rather grand trip from Switzerland to Spain in 1931. We know that he made it to Arles in the south of France, but whether he ever reached Spain is unclear. "Motorouta"; right - Davide Cislaghi wheel, 1923 "Dynosphere" for the geek driver in all of us Another fascinating chapter in monowheel history was written by a chap called Dr. John Archibald Purves from England, who seriously believed that one huge wheel encompassing five passengers was far more efficient than a car with four (smaller) wheels. In 1932, Purves designed the remarkable Dynosphere. This monowheel differed from other designs in various ways. For one, it was wide enough to stand up by itself, without the need of continuous and rather tricky balancing. The outside of the wheel was part of the surface of a sphere, so that it did not touch the ground over its entire width and could be tilted sideways for steering. The outside consisted of a metal framework, so that the driver could look through the openings in the wheel frame. (pictures provided by David Worth and Tom Anable) Purves built a few different prototypes that were either petrol-driven or electrically powered. These machines were tested on the beach at Brean Sands and at Brooklands racing track. A short surviving film clip of the latter shows the difficulty in making a smooth ride – even at fairly constant speed – without the occupants gerbilling back and forth inside the wheel. It has even said to have knocked someone over during this test-run because of the inadequate stering system. The project was soon abandoned after that. The last known news from the project was a finished model of a five-seating Dynosphere with an enclosed glassed-in cabin, complete with bumpers and headlights. link Here is the weirdest incarnation of Dynawheel, strange enough to reproduce the whole page (from Modern Mechanics, June 1935) - (image credit: modernmechanix.com) The 1930s saw a couple more unsuccessful monowheels, including the Monowheel Tank Project that never progressed beyond the drawing board, after which it was quiet for decades, when the monowheel made a come-back.
