ENGLISH 麻生希在线mxgs839Great crowds walked the long way to Tirlemont. They were constantly threatened by German soldiers, who aimed their rifles at them; passing officers commanded from time to time that some should stay behind, and others were shot. Especially did the clerics amongst the refugees suffer a great deal;145 many were not only scandalously scoffed at, but also maliciously injured. The greater part of the Germans showed a strong anti-Catholic bias, in particular against the clergy, whom they accused of having incited the people against them.Direct action and reaction are equal; if a force is exerted in any direction there must be an equal force acting in the opposite direction; a machine must absorb its own strains.

Upon entering the shop, a learner will generally, to use a shop phrase, "be introduced to a hammer and chisel;" he will, perhaps, regard these hand tools with a kind of contempt. Seeing other operations carried on by power, and the machines in charge of skilled men, he is likely to esteem chipping and filing as of but little importance and mainly intended for keeping apprentices employed. But long after, when a score of years has been added to his experience, the hammer, chisel, and file, will remain the most crucial test of his hand skill, and after learning to manipulate power tools of all kinds in the most thorough manner, a few blows with a chipping hammer, or a half-dozen strokes with a file, will not only be a more difficult test of skill, but one most likely to be met with.In practice this difference of effect on the top and bottom, or between the anvil and hammer sides of a piece, is much greater than would be supposed. The yielding of the soft metal on the top cushions the blow and protects the under side from the force. The effect produced by a blow struck upon hot iron cannot be estimated by the force of the blow; it requires, to use a technical term, a certain amount of force to "start" the iron, and anything less than this force has but little effect in moving the particles and changing the form of a piece.The general expatiated once more on the francs-tireurs of Louvain, and asked me to explain in my papers without fail that the citizens had to thank themselves for what had happened. The sergeant who had taken me to him was ordered to escort me, that I might not have any further trouble with the soldiers in the city.

At Blauwput, near Louvain, where, according to the Germans, there had been also shooting, many houses were set on fire and the men placed in a row. It was then announced that by way of punishment every fifth man would be shot. When the Germans counted as tenth the father of a large family, that man fainted, and they simply killed number eleven, a Capuchin.

But because the German libels go on accusing the Belgian people of horrible francs-tireurs acts, I have thought that I ought not to wait any longer before giving my evidence to the public.6. Danger, noise, vibration, and jar.Under certain conditions a given quantity of soft iron or steel may be cut away at less expense, and with greater accuracy, by milling than by any other process.

(1.) Why has the lifting of weights been made a standard for the measure of power?(2.) Name some of the difficulties to contend with in the operation of machinery for lifting or handling material.(3.) What analogy exists between manual handling and the operation of hydraulic cranes?(4.) Explain how the employment of overhead cranes saves room in a fitting shop.(5.) Under what circumstances is it expedient to move material vertically?(6.) To what circumstances is the danger of handling mainly attributable?Under certain conditions a given quantity of soft iron or steel may be cut away at less expense, and with greater accuracy, by milling than by any other process.CHAPTER XVII. MACHINERY FOR MOVING AND HANDLING MATERIAL.

31Reaction wheels are employed to a limited extent only, and will soon, no doubt, be extinct as a class of water-wheels. In speaking of reaction wheels, I will select what is called Barker's mill for an example, because of the familiarity with which it is known, although its construction is greatly at variance with modern reaction wheels.To the unskilled, or to those who do not take a comprehensive view of an engineering business as a whole, the finishing and fitting department seems to constitute the whole of machine manufacturean impression which a learner should guard against, because nothing but a true understanding of the importance and relations of the different divisions of an establishment can enable them to be thoroughly or easily learned.

Cutting tools include nearly all that are employed in finishing; lathes, planing machines, drilling and boring machines, shaping, slotting and milling machines, come within this class. The machines named make up what are called standard tools, such [120]as are essential and are employed in all establishments where general machine manufacture is carried on. Such machines are constructed upon principles substantially the same in all countries, and have settled into a tolerably uniform arrangement of movements and parts.

As no motion except rotary can be continuous, and as rotary movement of tools is almost exclusively confined to shaping cylindrical pieces, a proper distinction between machine tools which operate in straight lines, and those which operate with circular movement, will be to call them by the names of rotary and reciprocating.[170]
