      CHAPTER X. MACHINERY FOR TRANSMITTING AND DISTRIBUTING POWER.The good man's face became quite cheerful, he grasped my hand, deeply moved, and, pressing it warmly, said:


      89 4. Never heard the name of any franc-tireur in answer to my questions.


      Before I got to the bridge I saw something gruesome: a number of corpses of soldiers were lying about and others were brought in ... a little farther away, on the farm, there they were digging.... I looked away quickly; I was not yet accustomed to that sort of thing. Most likely they were men killed a moment ago by shells aimed at the bridge, for wounded men were also brought in on stretchers.

      The first and, perhaps, the most important matter of all in founding engineering works is that of arrangement. As a commercial consideration affecting the cost of manipulation, and the expense of handling material, the arrangement of an establishment may determine, in a large degree, the profits that may be earned, and, as explained in a previous place, upon this matter of profits depends the success of such works.

      232. The capacity of shafts is governed by their strength and the speed at which they run taken together.


      The frightened maidens were saying their rosary.

      It is not the intention to discuss patent law, nor even to estimate what benefits have in the past, or may in the future, be gained to technical industry by the patent system, but to impress engineering apprentices with a better and more dignified appreciation of their calling than to confound it with chance invention, and thereby destroy that confidence in positive results which has in the past characterised mechanical engineering; also to caution learners against the loss of time and effort too often expended [161] in searching after inventions.The arrangement of patterns with reference to having certain parts of castings solid and clean is an important matter, yet one that is comparatively easy to understand. Supposing the iron in a mould to be in a melted state, and to contain, as it always must, loose sand and 'scruff,' and that the weight of the dirt is to melted iron as the weight of cork is to water, it is easy to see where this dirt would lodge, and where it would be found in the castings. The top of a mould or cope, as it is called, contains the dirt, while the bottom or drag side is generally clean and sound: the rule is to arrange patterns so that the surfaces to be finished will come on the bottom or drag side.

      Cutting processes may be divided into two classes: cylindrical cutting, as in turning, boring, and drilling, to produce circular forms; and plane cutting, as in planing, shaping, slotting and shearing, to produce plane or rectangular forms. Abrading or grinding processes may be applied to forms of any kind.

      I will not consume space to explain the converse of this system of inventing, nor attempt to describe how a chance schemer would proceed to hunt after mechanical expedients to accomplish the valve movement in the example given."No!"
