Էջ 8 - H, extending outside of the boiler, and which is managed by the engineer. The operation of the machine is as follows : The steam being generated in great abundance, in the boiler, and being unable to escape out of it, acquires a considerable degree of elastic force. If, at that moment, the cock, V...
Էջ 347 - ISj oz. The number of gross tons that had passed on the rail, during that time, was estimated at 600,000. Thus we see that with so considerable a tonnage, and with the velocity of the motion on that railway, the annual loss of the rail was only -jj-j. of its primitive weight; so that it would require more than a hundred years to reduce it to the half of its present strength.
Էջ 2 - ... rails ; and our last chapter will contain a calculation of the quantity of fuel required for the traction of given loads. " These inquiries will be sufficient to solve all the most important questions concerning the application of locomotive engines to the draft of loads. " They will sometimes be necessarily subdivided into several branches, and require calculation and theoretical illustrations, of more or less extent, though always plain and easy, and a series of experiments more or less numerous...
Էջ 28 - Springs resting at oo on the chairs of the wheels, by means of vertical pins passing through holes in the frame of the engine. One end of the pin resting on the back of the spring, and the other on the upper side of the chair ; the whole weight of the machine is thus supported by the wheels, but through the intermediate action of the springs.

Էջ v - ... wish to acquire a knowledge of these engines and their employ on railways. Many questions had not even been entered into, others had been solved in a faulty manner. New researches on the subject became therefore indispensable. This work will, in consequence, be found completely different from 1 - A Practical Treatise on Railroads, and Interior Communication in general, by Nicholas Wood.- 1st edition, London, 1825; 2d edition, London, 1832.
Էջ 6 - From that construction it will easily be conceived, that the fire being shut up in the fire-box, and completely surrounded with water, none of its calorific parts are lost. Afterwards, the flame, in its way to the chimney, divides itself among all the small flues we have mentioned. It crosses thus the water of the boiler, having a considerable surface in contact with it, and only escapes after having communicated to the water as much as possible of the caloric it contained. Once arrived at the extremity...
