The Yeovil Car in 1897

The Yeovil motor car was a light business carriage for two persons. It was driven by a two-cylinder Petter patent petroleum engine, working on the Otto cycle, using ordinary petroleum. The cylinders were arranged side by side, and fired alternately. The explosions were effected by means of two ignition tubes, heated by a single blow lamp. The air inlet valves of the motor were operated by the suction of the piston, the exhaust valves by means of levers driven by chain gearing from the crank shaft. The motion was taken from the crank shaft to an intermediate by means of sprocket wheels and chains, reducing. A friction disc on the intermediate shaft was made to grip the chain wheel by lateral pressure applied to the end of the shaft by a hand lever. The intermediate shaft drives on to the rear axle by either one of two chains, the one gearing in a ratio of 12 to 32 and the other of 6 to 36, providing fast and slow speeds of ten and four miles respectively. A square clutch on the intermediate shaft between these two chains throws either one of them into action. The rear axle drives one only of the rear wheels of the carriage. The patent reversing motion is taken from the crank shaft by a belt. This belt drives a loose pulley carried on a foot lever. When reversing, the friction clutch for forward driving is released, the foot lever is held down, and the back of the belt pressed on to a pulley fixed on the intermediate shaft. A brake is held on the fly-wheel by a spring to control tbe engine when the carriage is at rest. When the carriage is in motion this brake is held off by a hand lever. Two pairs of ordinary carriage brakes are applied to the rear wheels, and the rever ing moprovide a strong additional brake in case of emergency
