CHAPTER XX. The Internal-combustion Engine

We have several times remarked upon the great handicap placed upon

the pioneers of aviation by the absence of a light but powerful motor

engine. The invention of the internal-combustion engine may be said to

have revolutionized the science of flying; had it appeared a century

ago, there is no reason to doubt that Sir George Cayley would have

produced an aeroplane giving as good results as the machines which have

appeared during the last five or six years.

The motor engine and the aeroplane are inseparably connected; one is as

necessary to the other as clay is to the potter's wheel, or coal to the

blast-furnace. This being the case, it is well that we trace briefly the

development of the engine during the last quarter of a century.

The original mechanical genius of the motoring industry was Gottlieb

Daimler, the founder of the immense Daimler Motor Works of Coventry.

Perhaps nothing in the world of industry has made more rapid strides

during the last twenty years than automobilism. In 1900 our road

traction was carried on by means of horses; now, especially in the large

cities, it is already more than half mechanical, and at the present rate

of progress it bids fair to be soon entirely horseless.

About the year 1885 Daimler was experimenting with models of a

small motor engine, and the following year he fitted one of his

most successful models to a light wagonette. The results were

so satisfactory, that in 1888 he took out a patent for an

internal-combustion engine--as the motor engine is technically

called--and the principle on which this engine was worked aroused great

enthusiasm on the Continent.

Soon a young French engineer, named Levassor, began to experiment with

models of motor engines, and in 1889 he obtained, with others, the

Daimler rights to construct similar engines in France. From now on,

French engineers began to give serious attention to the new engine,

and soon great improvements were made in it. All this time Britain held

aloof from the motor-car; indeed, many Britons scoffed at the idea of

mechanically-propelled vehicles, saying that the time and money required

for their development would be wasted.

During the years 1888-1900 strange reports of smooth-moving, horseless

cars, frequently appearing in public in France, began to reach Britain,

and people wondered if the French had stolen a march on us, and if there

were anything in the new invention after all. Our engineers had just

begun to grasp the immense possibilities of Daimler's engine, but the

Government gave them no encouragement.

At length the Hon. Evelyn Ellis, one of the first British motorists,

introduced the "horseless carriage" into this country, and the following

account of his early trips, which appeared in the Windsor and Eton

Express of 27th July, 1895, may be interesting.

"If anyone cares to run over to Datchet, they will see the Hon. Evelyn

Ellis, of Rosenau, careering round the roads, up hill and down dale,

and without danger to life or limb, in his new motor carriage, which he

brought over a short time ago from Paris.

"In appearance it is not unlike a four-wheeled dog-cart, except that the

front part has a hood for use on long 'driving' tours, in the event of

wet weather; it will accommodate four persons, one of whom, on the

seat behind, would, of course, be the 'groom', a misnomer, perhaps, for

carriage attendant. Under the front seat are receptacles, one for tools

with which to repair damages, in the event of a breakdown on the road,

and the other for a store of oil, petroleum, or naphtha in cans, from

which to replenish the oil tank of the carriage on the journey, if it be

a long one.

"Can it be easily driven? We cannot say that such a vehicle would be

suitable for a lady, unless rubber-tyred wheels and other improvements

are made to the carriage, for a grim grip of the steering handle and

a keen eye are necessary for its safe guidance, more especially if the

high road be rough. It never requires to be fed, and as it is, moreover,

unsusceptible of fatigue, it is obviously the sort of vehicle that

should soon achieve a widespread popularity in this country.

"It is a splendid hill climber, and, in fact, such a hill as that of

Priest Hill (a pretty good test of its capabilities) shows that it

climbs at a faster pace than a pedestrian can walk.

"A trip from Rosenau to Old Windsor, to the entrance of Beaumont

College, up Priest Hill, descending the steep, rough, and treacherous

hill on the opposite side by Woodside Farm, past the workhouse, through

old Windsor, and back to Rosenau within an hour, amply demonstrated how

perfectly under control this carriage is, while the sensation of being

whirled rapidly along is decidedly pleasing."

Another pioneer of motorism was the Hon. C. S. Rolls, whose untimely

death at Bournemouth in 1910, while taking part in the Bournemouth

aviation meeting, was deeply deplored all over the country. Mr. Rolls

made a tour of the country in a motor-car in 1895, with the double

object of impressing people with the stupidity of the law with regard

to locomotion, and of illustrating the practical possibilities of the

motor. You may know that Mr. Rolls was the first man to fly across the

Channel, and back again to Dover, without once alighting.
