      ��Another peculiar feature in trip-hammers is the rapidity with which crystallisation takes place in the attachments for holding the die blocks to the helves, where no elastic medium can be interposed to break the concussion of the dies. Bolts to pass through the helve, although made from the most fibrous Swedish iron, will on some kinds of work not last for more than ten days' use, and often break in a single day. The safest mode of attaching die blocks, and the one most common, is to forge them solid, with an eye or a band to surround the end of the helve.

      "No, I've none to sell."I pitied him from the bottom of my heart, and tried to console him by remarking that it was all a misunderstanding, and that I would see to it that he would soon be released.No one has been able to explain clearly why a sudden change of temperature hardens steel, nor why it assumes various shades of colour at different degrees of hardness; we only know the fact, and that steel fortunately has such properties.

      Strains caused by cutting action, in planing or other machines, fall within and are resisted by the framing; even when the tools are supported by one frame and the material by another, such frames have to be connected by means of foundations which become a constituent part of the framing in such cases.They sang and shouted and waved their arms. Most of them carried bottles full of liquor, which they put to their mouths frequently, smashed them on the ground, or handed them to their comrades, when unable to drink any more themselves. Each of a troop of cavalry had a bottle of pickles, and enjoyed them immensely.A finisher's engine lathe consists essentially of a strong inflexible shear or frame, a running spindle with from eight to sixteen changes of motion, a sliding head, or tail stock, and a sliding carriage to hold and move the tools.

      �The loss of effect by the inertia of the pieces acted upon increases with the weight of the work; not only the loss of power, but also the expense of heating increases with the size of the pieces. There is, however, such a difference in the mechanical conditions between light and heavy forging that for any but a heavy class of work there would be more lost than gained in attempting to operate on both sides of pieces at the same time.�

      My request to allow the child to stay at the café for half an hour was granted, and I went through the village towards the place whence the German batteries sent their destructive fire. At last I got as far as the top of a hill, from which I could see two forts shrouded in a cloud of smoke, which was also the case with the German batteries.Forging as a process in machine-making includes the forming and shaping of the malleable parts of machinery, welding or joining pieces together, the preparation of implements for forging and finishing, tempering of steel tools, and usually case-hardening.

      �In this way I got into conversation with a middle-aged lady. Her husband had been shot, and she got a bullet in her arm, which had to be amputated in consequence. The poor creature had lost all courage, and lived on her nerves only. It was remarkable to hear this father find the right words, and succeed in making her calm and resigned.138 Before she left us, she had promised that for her children's sake she would do all in her power to control herself.�

      What might happen next? Sitting on a chair in a corner of the room I began to consider my position. For the moment it was not agreeable, but by and by those officers might find time to look at my papers. The only thing I bothered about was a map marked with the places where, according to the latest news, the German and French armies were. I kept it in an inside coat-pocket, and it might be found if they should search me.A learner should, in fact, consider the application and operative conditions of gearing as one of the main parts of the subject, and the geometry or even the construction of wheels as subsidiary; in this way attention will be directed to that which is most difficult to learn, and a part for which facilities are frequently wanting. Gearing may be classed into five modifications—spur wheels, bevel wheels, tangent wheels, spiral wheels, and chain wheels; the last I include among gearing because the nature of their operation is analogous to tooth wheels, although at first thought chains seem to correspond more to belts than gearing. The motion imparted by chains meshing over the teeth of wheels is positive, and not frictional as with belts; the speed at which such chains may run, with other conditions, correspond to gearing.�

      ��By examining automatic hammers it will be found that their valves are connected to the drop by means of links, producing [162] coincident movement of the piston and valve, and that the movement of one is contingent upon and governed by the other. It will also be found that these connections or links are capable of extension, so as to alter the relative position of the piston and valve, thereby regulating the range of the blow, but that the movement of the two is reciprocal or in unison. Reasoning inductively, not discovering or inventing, it may be determined that to secure a stamp blow of a hammer-head, the valve must not open or admit steam beneath the piston until a blow is completed and the hammer has stopped.

      "2. Kleyer, burgomaster of Liège.Presuming the reader to remember what was said of steam hammers in another place, and to be familiar with the uses and general construction of such hammers, let it be supposed steam-hammers, with the ordinary automatic valve action, those that give an elastic or steam-cushioned blow, are well known. Suppose further that by analysing the blows given by hammers of this kind, it is demonstrated that dead blows, such as are given when a hammer comes to a full stop in striking, are more effectual in certain kinds of work, and that steam-hammers would be improved by operating on this dead-stroke principle.In front of me, behind me, on all sides, the guns boomed, clouds of dust and smoke filled the air, making it impossible to see much, which made the awe and terror endurable; but after the air became clear again, and the sun shed glowing light on the beautiful fields, it was terrible to think that all those dots in the plain were the bodies of young men, cruelly crushed by the infernal products of human ingenuity. It was agony to see here and there a body rising up, merely to fall down again immediately, or an arm waving as if invoking help.
