"The failure of the steam-valve, as I have always told you, was due to my own carelessness, Sallie. I should have patented it sooner. They are making enormous sums on it, I hear, and are using my cut- off, and I think dishonestly. But the motor has been protected at every new step that I have taken. My first patent of August 13, 1856, supersedes all others, and cannot be shaken.
The Indians had first mounted the engine, and half stunned the engineer and stoker with blows from their muskets. A Sioux chief, wishing to stop the train, but not knowing how to work the regulator, had opened wide instead of closing the steam-valve, and the locomotive was plunging forward with terrific velocity.
The steam-valve is a packed slide with but little lap, and the expansion-valve is an adjustable slide working on the back of the steam-valve. The boilers are of the vertical water-tube type, with the tubes above the furnaces, and are supplied with fresh water by tubular surface-condensers, which, together with the air-pumps, are placed opposite the cylinders.
With the uproar of the gale around him he applied alternately his lips and his ear, and the engineer's voice mounted to him, harsh and as if out of the heat of an engagement. One of the stokers was disabled, the others had given in, the second engineer and the donkey-man were firing-up. The third engineer was standing by the steam-valve. The engines were being tended by hand. How was it above?
By this means the shaft, K, is relieved of all side pressure. The exhaust-port, which is very large and relieves all back pressure, is shown at D. The pistons and disks are made to balance at the speed at which the engine is intended to run. The steam-valve, for which patent is pending, is new in principle. It has a uniform rotating motion, and, like the engine, is steam and mechanically balanced.

The Hertzian waves wouldn't be strong enough to work a great heavy Morse instrument like ours. Let me make it clearer. Do you know anything about steam?" "Very little. But go on." "Well, the coherer is like a steam-valve. Any child can open a valve and start a steamer's engines, because a turn of the hand lets in the main steam, doesn't it?
Then, my dear, you won't have to curtail your expenses as you have done." His voice was full of hope now, a smile lighting his face as he thought of all the pleasure and comfort his success would bring her. "But you said that same thing when you were working on the steam-valve, for which you put that very mortgage on the farm, and now that's all gone and "
