Slowly he raised his eyes to a level with the illuminated window, and peered in. A strange sight greeted him. Shine Taylor was busily engaged in the 'twisting of coils of wire, about shiny brass cylinders, with an array of small and large clocks, electric batteries and mysterious bottles on the carved library table. He was intent upon the manufacture of another of his diabolical engines of death!
The message was dropped down in one of Larry's leather cylinders. It was seen to be picked up and while Dick and his friends circled about above the aviation grounds their note was read. An answer was hastily prepared to be sent up as Lieutenant McBride had suggested. Meanwhile a number of the other aeroplanes whizzed past, close to Dick's.
Two liquefied gases which, when united, exploded spontaneously were admitted by a clockwork escapement in minute quantities into the cylinders of his engine, and worked the pistons by the expansive force of the gases generated by the explosion. There was no weight but the engine itself and the cylinders containing the liquefied gases.
In 1817, in the side-alleys of this same Champ de Mars, two great cylinders of wood might have been seen lying in the rain, rotting amid the grass, painted blue, with traces of eagles and bees, from which the gilding was falling. These were the columns which two years before had upheld the Emperor's platform in the Champ de Mai.
A light steel manifold serves to connect the exhaust ports of the cylinders to the main exhaust pipe, which is inclined about 25 degrees from vertical and is arranged to give on to the atmosphere just over the top of the upper wing of the aeroplane. As regards carburation, an automatic air valve surrounds the throat of the carburettor, maintaining normal composition of mixture.
He dashed into the road to Hoboken, and found, to his joy, that the dust raised by the passage of the car gave an unfailing clue to its route. Now, a well-regulated motor-cycle can run rings round any other form of automobile, no matter how many horses may be pent in the cylinders, if on an ordinary road and subjected to the exigencies of traffic.
The larger the wheels, the less the power, and the higher the velocity which may be got; again, the wheel remaining of the same size, by enlarging the dimensions of the cylinders the power is increased; and the wheels and cylinders remaining the same, by enlarging the boiler we can make stronger steam and thus increase the power.
And lying in a line along its length, vanishing at last far away in that tremendous perspective, were a number of huge shapes, huge pallid hulls, upon which the Selenites were busy. At first they seemed big white cylinders of vague import.
The liquor, which is drawn through the cloth into the inside of the cylinders by the centrifugal pumps, is discharged back into the cistern by a specially constructed discharge pipe, so devised that the liquor, which is sent into it with great force by the pump, is diverted so as to pour straight down in order to prevent any eddies which could cause the cloth to wander from its course.
The form of the boat seemed to be an admirable one, and it rode on the waves like a water bird; but, at the same time, it was extremely slow in its progress. When we were a little more than half way across the reach, two of the divisions between the cylinders gave way, and it required the constant use of the bellows to keep in a sufficient quantity of air.
