      �Fitting processes, being the final ones in constructing machinery, are more nearly in connection with its use and application; they consist in the organisation or bringing together the results of other processes carried on in the draughting room, pattern shop, foundry, and smith shop.These are, however, not the only reasons which have led to a running platen for planing machines, although they are the most important.

      23Screw-cutting machines may be divided into modifications as follows:—(1) Machines with running dies mounted in what is called the head; (2) Machines with fixed dies, in which motion is given to the rod or blank to be threaded; (3) Machines with expanding dies which open and release the screws when finished without running back; (4) Machines with solid dies, in which the screws have to be withdrawn by changing the motion of the driving gearing; making in all four different types."I refuse to sell 'bikes' to Germans."




      �"That way, sir!"�


      The similarity of the operations carried on in all works directed to the manufacture of machinery, and the kind of knowledge that is required in planning and conducting such works, would lead us to suppose that at least as much system would exist in machine shops as in other manufacturing establishments, which is certainly not the case. There is, however, this difference to be considered: that whereas many kinds of establishments can be arranged at the beginning for a specific amount of business, machine shops generally grow up around a nucleus, and are gradually extended as their reputation and the demands for their productions increase; besides, the variety of operations required in an engineering establishment, and change from one class of work to another, are apt to lead to a confusion in arrangement, which is too often promoted, or at least not prevented, by insufficient estimates of the cost of handling and moving material.�


      Designing, or generating the plans of machinery, may be considered the leading element in engineering manufactures or machine construction, that one to which all others are subordinate, [75] both in order and importance, and is that branch to which engineering knowledge is especially directed. Designing should consist, first, in assuming certain results, and, secondly, in conceiving of mechanical agents to produce these results. It comprehends the geometry of movements, the disposition and arrangement of material, the endurance of wearing surfaces, adjustments, symmetry; in short, all the conditions of machine operation and machine construction. This subject will be again treated of at more length in another section.So at last the lock of the heavy door screeched, and I was admitted. I noticed that about a score of sisters had gathered behind the gate and were anxiously discussing the "strange occurrence." My meeting with S?ur Eulalie, however, was so cordial that the good nuns lost all anxiety, and I was taken inside accompanied by nearly all the inmates of the convent.As these shop processes or operations are more or less connected, and run one into the other, it will be necessary at the beginning to give a short summary of them, stating the general object of each, that may serve to render the detailed remarks more intelligible to the reader as he comes to them in their consecutive order.

      Another principle to be noticed in connection with hammers and forging processes is that of the inertia of the piece operated upon—a matter of no little importance in the heavier kinds of work.Nothing animate or inanimate in nature is uniform; plants, trees, animals, are all different; even the air we breathe and the temperature around us is constantly changing; only one thing is constant, that is time, and to this must we go for all our standards.While all the others were denouncing me, one soldier was ready to believe that I was a peaceful foreign journalist, and that all the misunderstanding would disappear the next morning as soon as I should be taken to the commanding officer. He took pity on me, and got a thick soldier's coat for me as cover. I still feel grateful to the man for it! But sleep was out of the question on that wet floor, in the dense fog. When the guard was changed and soldiers came back, or others went, they could not see in the dark where they went, and treated me to a kick against my head or some other part of my body.

      Patterns and castings are so intimately connected that it would be difficult to treat of them separately without continually confounding them together; it is therefore proposed to speak of pattern-making and moulding under one head.�I had walked another three miles, when a big crowd of fugitives met me. They seemed to have come a long way, for the majority could hardly walk on, and had taken off their shoes and boots, on account of the scorching heat, going on barefooted in the shade of the tall trees. It was a procession, numbering hundreds of men, women, and children. The aged were supported, the babies carried. Most of them had a small parcel on their back or under their arm. They seemed tired to death, had dark red faces, and betrayed great fear and nervousness. I crossed the road to speak to them, and as soon as they noticed it the whole crowd, numbering hundreds of people, stood still, creeping closer together, women and girls trying hard to hide themselves behind the men, and these doffed their caps timidly.

      �In working to regular scales, such as one-half, one-eighth, or one-sixteenth size, a good plan is to use a common rule, instead of a graduated scale. There is nothing more convenient for a mechanical draughtsman than to be able to readily resolve dimensions into various scales, and the use of a common rule for fractional scales trains the mind, so that computations come naturally, and after a time almost without effort. A plain T square, with a parallel blade fastened on the side of the head, [80] but not imbedded into it, is the best; in this way set squares can pass over the head of a T square in working at the edges of the drawing. It is strange that a draughting square should ever have been made in any other manner than this, and still more strange, that people will use squares that do not allow the set squares to pass over the heads and come near to the edge of the board.The permanent contraction of steel in tempering is as the degree of hardness imparted to it by the bath.
