The piston is thus urged alternately up and down the valve so changing its position before the piston arrives at the end of the stroke, that the pressure is by that time thrown on the reverse side of the piston, so as to urge it into motion in the opposite direction. Q. Is the motion of the valve, then, the reverse of that of the piston? A. No.
To meet this condition of facts, Colonel Mason ordered that liberal furloughs should be given to the soldiers, and promises to all in turn, and he allowed all the officers to draw their rations in kind. As the actual valve of the ration was very large, this enabled us to live. Halleck, Murray, Ord, and I, boarded with Dona Augustias, and turned in our rations as pay for our board.
His visit resulted in the purchase of a life-preserver, which he took home with him for the purpose of examining it. Subjecting it to a careful investigation, he discovered a defect in the valve used for inflating it, and promptly devised a simpler and better apparatus.
This was effected by a screw which raised the valve from its bearings at the first partial turn of the screw, after which there was no further resistance or friction, except the trifling friction of the screw in its nut on the upper part of the sluice-valve.
In this connection it has occurred to me that passenger elevators could be built at no great additional cost, with two cylinders, small and large, the two piston rods of which could be connected so as to both operate the same cable, either or both furnishing power, the smaller cylinder to be used for light loads, the larger for heavy work, and the two together for full capacity, this independent valve arrangement to be controlled by a separate cable running through the car.
If he may be said to have thrown a bomb, he certainly had attached a safety valve to it, for the investigation which he proposed could not but give time for the passions produced by his message to cool.
Sixteen hundred feet of 6-inch and 300 feet of 4-inch cast iron pipe furnish the means of distribution; eight 2½-inch double discharge fire hydrants were located on the principal streets. A gate valve was placed in the 6-inch main close to the elbow on lower end of the down pipe from the tank.
"Well, sir, we shot up about a thousand feet more, and then Jones dropped the lunch-basket overboard by accident, and we went up nearly four miles Conly got blue in the face, Jones fainted, and I came near going under myself. A minute more we'd all've been dead men; but I gave the valve a jerk, and we came down like a rocket-stick.
For these reasons we would employ a hot water pipe or pipes, passing around the house, on the same level with the tanks, supplied with a valve to regulate the heat at pleasure, or a brick smoke flue constructed in the usual manner.
Such a system may be adopted and made actual use of that will point out at once the exact condition of every part of this business, and provide a safety valve which will indicate at all times the true profit or loss, and through just what channel that loss or gain accrues. Filing Correspondence.
