The jet should be connected with the tube entering the wash-bottle by a short piece of rubber tubing in such a way as to be flexible, and should deliver a stream about one millimeter in diameter. The neck of the flask may be wound with cord, or covered with wash-leather, for greater comfort when hot water is used.
G1 is abreast of the mouth of the pump, G2 about half an inch forward of the end of the cylinder. The striker, S, is a piece of brass strip soldered to 1/2 inch of tubing fitting the piston rod. The collar is tapped for two screws, which prevent S slipping on the piston rod. The rods for R1 R2 are now provided with forks, made by cutting and filing notches in bits of brass tubing.
The up-flow end, which projects farther through the bottom than the down-flow, is nearer the centre, where, if a gas stove is used, the heat is more intense than at the circumference of the bottom. The copper tubing should be annealed or softened by heating to a dull red and plunging in cold water.
The reduction of the voltage was accomplished as follows: The 100,000-volt alternating current was received through an oil switch and was conveyed to a high-tension current distributor made up of three lines of copper tubing, thus forming the source of power for this station.
"This, as you possibly know, sir, is a piece of electric tubing made for the express purpose of conveying safely delicate electric wirings that are used for installations, so that they may not be damaged in transit from the factory to the agent who sells them.
The power cylinder is a piece of brass tubing 2 inches long and of 7/8-inch internal diameter. The piston is of 7/8-inch tubing, fitting the cylinder easily, and thick enough to allow a shallow packing recess to be turned in the outside. Brass washers turned or filed to size form the ends of cylinder and piston.
Care must be taken to hold the tube at right angles to the flame during the heating, and to rotate it so that only a narrow strip of the circumference is heated, and the scratch should be in the center of this heated strip. By this means tubing as large as two inches in diameter is readily broken.
"Why don't you get a portable stove?" "Oh, heavens! that would asphyxiate us." "It wouldn't be very comfortable at any rate," said Des Hermies, "for there is no chimney. You might get some joints of pipe and run them out of the window, the way you have fixed this tubing.
The questioner seemed to know all about everything, so it was easy for him to lead Jimmie to tell how he had heard Kumme cursing the Empire Shops, and the country, and the President; how he had seen Kumme whispering to Reilly, and to Germans whose names he had not learned, and how he had seen Heinrich, Kumme's nephew, cutting up lengths of steel tubing.
