      First. By combining two or more operations in one machine, the only objects gained are a slight saving in first cost, one frame answering for two or more machines, and a saving of floor room. CHAPTER IVBeginning at the tool there is, first, a clamped joint between the tool and the swing block; second, a movable pivoted joint between the block and shoe piece; third, a clamped joint between the shoe piece and the front saddle; fourth, a moving joint [131] where the front saddle is gibed to the swing or quadrant plate; fifth, a clamp joint between the quadrant plate and the main saddle; sixth, a moving joint between the main saddle and the cross head; seventh, a clamp joint between the cross head and standards; and eighth, bolted joints between the standards and the main frame; making in all eight distinct joints between the tool and the frame proper, three moving, four clamped, and one bolted joint.

      "The Russians advanced fifty miles into East Prussia."It may be noticed that the carriages of some lathes move on what are termed V tracks which project above the top of lathe frames, and that in other lathes the carriages slide on top of the frames with a flat bearing. As these two plans of mounting lathe carriages have led to considerable discussion on the part of engineers, and as its consideration may suggest a plan of analysing other problems of a similar nature, I will notice some of the conditions existing in the two cases, calling the different arrangements by the names of flat shears and track shears.�

      (1.) In what respect are air and water like belts and gearing, as means to transmit power?—(2.) What are some of the principal advantages gained by employing air to operate railway brakes?—(3.) Name some of the advantages of centralising motive power.—(4.) Are the conditions of working an engine the same whether air or steam is employed?"6. Eduard Peltzer, senator."And what is the news in The Netherlands about the war?"

      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.��

      The range and speed of movement of the parts of machines are elements in designing that admit of a definite determination from the work to be accomplished, but arrangement cannot be so determined, and is the most difficult to find data for. To sum [154] up these propositions we have:—Steam-hammers are divided into two classes—one having the valves moved by hand, and the other class with automatic valve movement.

      "Have you got papers?"45 All the forts thundered away again, and the guns of the Germans were also busy on the citadel and the various surrounding heights. Already early in the morning a terrible and suffocating smoke of fire and gunpowder hovered over Liège. The smoke came down also from the burning villages, like Bressoux, on the slopes of the hills near Liège. The flames flared up from the houses and offered a melancholy sight.The successful application of the pneumatic system at the Mont Cenis Tunnel in Italy, and at the Hoosac Tunnel in America, has demonstrated the value of the system where the air not only served to transmit power to operate the machinery but to ventilate the mines at the same time. Air brakes for railway trains are another example illustrating the advantages of pneumatic transmission; the force being multiplied at the points where it is applied, so that the connecting pipes are reduced to a small size, the velocity of the air making up for a great force that formerly had to be communicated through rods, chains, or shafts. The principal object attained by the use of air to operate railway brakes is, however, to maintain a connection throughout a train by means of flexible pipes that accommodate themselves to the varying distance between the carriages. Presuming that the flow of air in pipes is not materially impeded by friction or angles, and that there will be no difficulty in maintaining lubrication for pistons or other inaccessible parts of machinery when driven by air, there seems to be many reasons in favour of its use as a means of distributing power in manufacturing districts. The diminished cost of motive power when [56] it is generated on a large scale, and the expense and danger of maintaining an independent steam power for each separate establishment where power is employed, especially in cities, are strong reasons in favour of generating and distributing power by compressed air, through pipes, as gas and water are now supplied.

      The next morning I got up early, having been unable to sleep. I realised already that my task was difficult, dangerous, and full of responsibility, for I had to find out and communicate to the public the truth about events, which would be related as beautiful or horrid, according to the interests of my informants. It was dangerous, because I might meet with the same fate that seemed to have been inflicted on so many civilians already.Whether neutral or foreigner, no one could help being deeply moved. Men and women, boys and girls, pressed once more through the German fence, just to shake hands with someone they had recognised. No wailing followed, but when hands were gripped, with a suppressed sob, they said:The following are suggested as subjects which may be studied in connection with lathes and turning: the rate of cutting movement on iron, steel, and brass; the relative speed of the belt cones, whether the changes are by a true ascending scale from the slowest; the rate of feed at different changes estimated like the threads of a screw at so many cuts per inch; the proportions of cone or step pulleys to insure a uniform belt tension, the theory of the following rest as employed in turning flexible pieces, the difference between having three or four bearing points for centre or following rests; the best means of testing the truth of a lathe. All these matters and many more are subjects not only of interest but of use in learning lathe manipulation, and their study will lead to a logical method of dealing with problems which will continually arise.

      2. Plans of adaptation and arrangement of the component parts of the machinery, or organisation as it may be called.3. The strains to which shafts are subjected are the torsional strain of transmission, transverse strain from belts and wheels, and strains from accidents, such as the winding of belts.�

      "Go farther, sir? But ... but ... sir, don't do that! The Germans shoot every civilian whom they set eyes on."��
