The real chauffeur knows every moment by the sound and "feel" of his machine exactly what it is doing, the amount of gasoline it is taking, whether the lubrication is perfect, the character and heat of the spark, the condition of almost every screw, nut, and bolt, and he runs his machine accordingly; at the first indication of anything wrong he stops and takes the stitch in time that saves ninety and nine later.
Small wonder was this when the cost, even of these earliest and clumsiest of atomic engines, is compared with that of the power they superseded. Allowing for lubrication the Dass-Tata engine, once it was started cost a penny to run thirty-seven miles, and added only nine and quarter pounds to the weight of the carriage it drove.
With a mixture of hog's lard and olive oil interposed between the surfaces, the friction was usually from 1/12th to 1/14th of the load, but in some cases it was only 1/20th of the load. Q. May water be made to serve for purposes of lubrication?
The small leakage of water into the vessel which is thus occasioned, keeps the screw shaft in this situation always wet, and this is all the lubrication which this bearing requires or obtains. Q. What is the utmost pressure which may be employed without heating when oil is the lubricating material? A. That will depend upon the velocity.
Lubrication of the four bearings, which are of the self-adjusting, ball and socket pattern, is effected by supplying an abundance of oil to the middle of each bearing and allowing it to flow out at the ends. The oil is passed through a tubular cooler, having water circulation, and pumped back to the bearings.
Where a bilateral affection exists, two or three weeks' time should intervene between the treatments of each leg. A sterile metal syringe equipped with a slip joint for the needle is well adapted to this operation. Lubrication of the plunger with heavy sterile vaseline or glycerin will prevent the syringe from being ruined by the iodin.
As the pieces are thus detached from the bulk, they are laid on stools or tables, or in stalls or carts, according to the method by means of which the necessary amount of oil and water is to be added for the essential process of lubrication; this lubrication enables the fibre to work freely in the various machines. Softening and Softening Machines.
This cooling is rendered necessary, because without it the oil would be carbonized, and lubrication of the cylinder rendered impossible. Indeed, a similar difficulty has occurred with all hot-air engines, and is, I think, the reason they have not been more generally adopted.
They give great promise of advancement, the hitherto insuperable difficulties of lubrication and packing having been overcome within the last five years. Superheating especially promises to yield substantial results as compared with the practice with ordinary engines, but the margin of saving in steam over the best quadruple expansion engine cannot be great.
In the days when Queen Victoria was the grandmother of Europe this was a plausible argument. King, Czar and Emperor, or Emperor and Emperor would meet, and it was understood that these meetings were the lubrication of European affairs. The monarchs married largely, conspicuously, and very expensively for our good.
