With the moonlight lying like a benediction over the fields and forests of Maine, the Snowbird, her motor humming like a huge bumble-bee, and her propellers and controls working in perfect order, swept on her course into the northwest. The lights of Easton, ten miles from their home, melted into the earth-shadow behind the sky-voyagers within the first hour of the sure-to-be eventful journey.
The Solarite gave a violent lurch as it shot vertically aloft at tremendous acceleration. Arcot reached over swiftly and snapped the switch of the microphone. There burst in upon them the familiar roaring drone of a hundred huge propellers. No slightest hum of motor, only the vast whining roar of the mighty props. "Another one! They must have been following the first by a few minutes.
The boats were towed backwards and forwards by Indian swimmers one at the bow, and one at the stern as steersman, and two on each side as propellers. The poor fellows, when they came out of the cold water, trembled as if attacked with an ague. We encamped near the house of Mr. L. being absent.
On land two big aërial propellers, geared to the engine, drove the Wondership swiftly along on four solid-tired wheels. When it was desired to take to the air the balloon bag, which was neatly folded on a framework supported by upright stanchions above the body of the car, was inflated by turning on a valve connecting with the gas tanks in the base of the body.
The former agreed to take such vessels as we required into dock as rapidly as possible, where Xodar would direct their equipment with water propellers. For many years the black had been in charge of the refitting of captured battleships that they might navigate Omean, and so was familiar with the construction of the propellers, housings, and the auxiliary gearing required.
Among the propellers receiving their engines from the Cuyahoga Works were the Winslow, Idaho, Dean Richmond, Ironsides, S. D. Caldwell, Meteor, and a very large number of others, besides a great many first-class steam tugs plying on Detroit river. In 1853, the introduction of the manufacture of locomotives added a new feature to the manufacturing industry of Cleveland.
Had it loosened the obstructing log so that the boat could pass out into the Beni river? Had the concussion damaged the propellers so that the trip up the valley of the Amazon would have to be abandoned? These questions were in the minds of all three boys as Jack cautiously opened a rear panel and looked out.
It's the density that makes the difference, Mr. Damon. If air were as dense as water we could have comparatively slow-moving motors and propellers and " "Ha! There you have it, Tom! And there is where my Whizzer Wakefield Damon's Whizzer is going to revolutionize air travel!" cried the eccentric man. "The difference in density! If air were as dense as water the problem would be solved.
There was a fine bright moon mounting above the housetops of the water-front when we slid away from our jetty berth. Slid is the word. She was all power, this Channel steamer of hardly 1,500 tons, yet with two great smoke-stacks, three propellers, turbine-engines, and burning oil for fuel. That last is a cheerful item when you have to walk the deck it means no cinders in your eyes. Fuss?
The inventor has perfected an ingenious, simple, and highly efficient coupling device to attain this end, but to ensure that the propeller output is of the maximum efficiency in relation to the engine, the pitch of the propellers may be altered and even reversed while the engine is running.
