Making the Cylinder Slide and Valve. The cylinder barrel must be perfectly cylindrical and free from any dents. Mandrel-drawn brass tubing, 1/16-inch thick, may be selected. If you cannot get this turned off at the ends in a lathe, mark the lines round it for working to with the aid of a perfectly straight edged strip of paper, 2-13/16 inches wide, rolled twice round the tube.
For this reason the whole neighborhood of the joint must be heated somewhat so that there may not be stresses set up between the heated and unheated portions. Very fine capillary tubing should be blown with a rubber bulb instead of the mouth, so as not to get moisture into the tube. The rubber bulb may also be used to advantage on some of the coarser capillary tubing.
The first arrival, after the spectators had assembled, was the last load of tubing, and Bob's only trouble was, or he professed that it was, that they would lose so much oil before they could make arrangements for storing it. As the time went on, Bob was the only one who had anything to do, and those who watched him insisted that he simply did the same work over and over again.
It was in 1890 that I began on a double-cylinder engine. It was quite impractical to consider the single cylinder for transportation purposes the fly-wheel had to be entirely too heavy. Between making the first four-cycle engine of the Otto type and the start on a double cylinder I had made a great many experimental engines out of tubing. I fairly knew my way about.
According to the nature of the harmony, one only, or both together below the suspension, or one above and one below, are used. The weight of the lower pendulum, or deflector, is supported on a disc, resting on a pin passing through the bottom of a piece of brass tubing, which is provided with an eye at its upper end.
With a final hard smash, the grate gave way, clattering into the recesses of the refrigerating unit. Now Tom was grateful for the roar of the jets. It covered the sound of his escape. Quickly reaching down into the unit, Tom began tearing the mechanism apart; ripping out coils of copper tubing and rubber connections.
On the completion of each layer, or sometimes two layers, the necessary measured amount of oil is evenly sprayed by hand over the pieces from cans provided with suitable perforated outlets usually long tubes. After the oil has been added, water, from a similar sprayer attached by tubing to a water tap, is added until the attendant has applied what he or she considers is the proper quantity.
Now procure a piece of small brass tubing with an internal diameter a little less than that of the turned down portion of your taper. If the brass tubing cannot be procured readily, you can substitute a piece of brass wire a little larger than the taper, and by means of a drill a little smaller in diameter than the turned down portion you can readily make a small tube about one-half inch long.
After the boring has been successfully accomplished, the next operation consists in tubing the well. This is merely the introduction of a copper or iron chamber, extending down, or nearly so, to the vein of the oil.
The boys drove to Fremont Street, past the incredible gambling halls with their elaborate signs and miles of neon tubing. Scotty remarked, "I guess you and that deputy sheriff were right. It takes an awful lot of lost money to keep all these places going." Tiring of the neon wilderness they turned north on Main Street and headed out toward Nellis Air Force Base.
