De Dion Bouton motor tricycle, by the Motor Manufacturing Co. Coventry, 1898. This tricycle is a copy of the French machines which embodied improvements patented by Count Albert De Dion and Charles Bouton in 1895. A vertical single-cylinder air-cooled engine is mounted behind the rear axle which it drives through spur gearing.
Following the invention by Gottlieb Daimler in 1885 of the surface vaporiser for supplying an ignitable air-petrol mixture, various specialised types were evolved for both cars and motor cycles. The example shown is one of the best known of this period, and was used extensively on the De Dion motor tricycle.
The sheet metal petrol container has an air inlet tube with a slidable horizontal baffle by means of which the incoming air, induced by the suction of the engine, is directed over the surface of the petrol. The resulting air-petrol vapour flows through the cylindrical mixing chamber and is controlled by a barrel throttle; a second barrel throttle admits extra air. The mixing chamber is connected to the inlet port of the engine by a pipe. A small pipe connecting with the exhaust pipe passes through the petrol in the container to assist vaporisation. A float with a long wire indicator shows the quantity of petrol in the container.
