Side 287 - To the length of the edge of the wedge, add twice the length of the back ; multiply this sum by the height of the wedge, and then by the breadth of the back ; one-sixth of the product will be the solid contents.
Side 209 - There he stands, champing and foaming upon the iron track, his great heart a furnace of glowing coals ; his lymphatic blood is boiling in his veins ; the strength of a thousand horses is nerving his sinews; he pants to be gone. He would " snake
Side 223 - Besides these advantages, this system possesses others of still more importance to the public. No collision between trains can take place, for as the power cannot be applied to more than one piston at a time in the same section of pipe, the trains must ever be the length of a section apart from each other ; and if from any cause a train should be stopped in the middle of a section, the train which follows it will be obliged to stop also at the entrance of the pipe, as there will be no power to propel...
Side 223 - ... that the engine will scarcely draw more than itself and tender. An additional waste of fuel, to an immense extent, is also occasioned by the loss of power (as already shown) on inclined planes. And, lastly, the chances of accident from collision, running off the rail, bursting of boilers, etc. ; * * * From the foregoing remarks it will appear that the evils of the present system are entirely attributable to the use of locomotive power, and the remedy must be sought for. in the employment of stationary...
Side 209 - How the giant creature struts forth from his stable, panting to be gone! His great heart is a furnace of glowing coals; his lymphatic blood is boiling in his veins; the strength of a thousand horses is nerving his iron sinews. But his master reins him in with one finger, till the whole of some western village, men, women, children, and half their horned cattle, sheep, poultry, wheat, cheese, and potatoes, have been stowed away in that long train of waggons he has harnessed to his foaming steam-horse.
Side 223 - The weight of the rails and chairs on the new system may be less by one-third than where locomotive engines are employed, as the carriages of the train will be too light to injure them. The annual charge of maintenance of way will, from the same cause, be reduced to a considerable extent. 3rd. The wear and tear of locomotive, compared with stationary engines, is as 18 to 1. 4th. By the new system the full power of the engines is always obtained ; and on an incline the additional quantity of fuel...
Side 218 - ... from the barometric gauges fixed at both ends of the pipe the vacuum is ascertained to be formed to an equal extent throughout the whole length without any appreciable difference of time. The pipe laid down is 9 inches diameter, and half a mile long, and a pressure equal to a column of mercury 18 inches high is obtained in one minute by an air-pump 37$ inches diameter, moving through 165 feet per minute. Now it is obvious that if the transverse section of the pipe be increased to any extent,...
Side 253 - Wales, erected a machine at a powerful fall of water, which worked a set of cylinder bellows, the blow-pipe of which was conducted to the distance of a mile and a half, where it was applied to a blast furnace ; but notwithstanding every care to make the conducting pipe very airtieht, of great size, and as smooth as possible, it would hardly blow out a candle.
