THREE:(1.) What change has taken place in the meaning of the name "invention" as applied to machine improvement?(2.) What should precede an attempt to invent or improve machinery?(3.) In what sense should the name invention be applied to the works of such men as Bentham, Bodmer, or Stephenson?A proof of this last proposition is found in the fact that a thorough latheman will perform nearly as much work and do it as well on an old English lathe with plain screw feed, as can be performed on the more complicated lathes of modern construction; but as economy of skill is sometimes an equal or greater object than a saving of manual labour, estimates of tool capacity should be made accordingly. The main points of a lathe, such as may most readily affect its performance, are firsttruth in the bearings of the running spindle which communicates a duplicate of its shape to pieces that are turned,second, coincidence between the line of the spindle and the movement of the carriage,third, a cross feed of the tool at a true right angle to the spindle and carriage movement,fourth, durability of wearing surfaces, especially the spindle bearings and sliding ways. To these may be added many other points, such as the truth of feeding screws, rigidity of frames, and so on, but such requirements are obvious.
THREE:Suddenly several shots sounded in the neighbourhood. The three took their rifles and looked round, somewhat scared. They assured me that they would protect me. If there had been occasion for it, it would have been against their own comrades,117 for a troop of soldiers came sailing along, swinging about their rifles and shooting at the burning houses as they walked on, without rhyme or reason, anyhow and anywhere. These were drunk also. At last I was able to shake off my "friends," and got through another street into the market-place, at the town-hall and St. Peter's Church. The beautiful town-hall happily was not destroyed, as the first reports intimated, but St. Peter's had been damaged most cruelly. The spire had disappeared, the roof collapsed, windows broken, the altar burned, the pulpit badly damaged, and so forth. The two last-named parts were fine works of art.Nobody replied. They were all under her own roof, they had all enjoyed her hospitality times out of mind, but not one of them was prepared to lend her money. And Leona had had a fearful run of luck lately. Out of all those dainty smiling friends of hers seated round that table there was not one who did not hold her I.O.U. for considerable sums of money. She was beginning to be talked about. That very morning in the Park a well-known society leader had ignored her until recognition was forced upon her by sheer audacity.
THREE:CHAPTER VI. ON THE NATURE AND OBJECTS OF MACHINERY.
THREE:At this point will occur one of those mechanical problems which requires what may be called logical solution. The valve must be moved by the drop; there is no other moving mechanism available; the valve and drop must besides be connected, to insure coincident action, yet the valve requires to move when the drop is still. Proceeding inductively, it is clear that a third agent must be introduced, some part moved by the drop, which will in turn move the valve, but this intermediate agent so arranged that it may continue to move after the hammer-drop has stopped.
THREE:Various other anecdotes of more or less doubtful authenticity are related, showing that the philosopher could generally, though not always, act up to his own ideal of indifference. He lived with his sister, who was a midwife by profession, and patiently submitted to the household drudgery which she unsparingly imposed on him. Once, however, she succeeded in goading him into a passion; and on being rather inoppor141tunely reminded of his professed principles by a bystander, the sceptic tartly replied that a wretched woman like that was no fit subject for a display of philosophical indifference. On another occasion, when taunted for losing his self-possession at the attack of a furious dog, he observed, with truth, that, after all, philosophers are human beings.228
