When the Civil war broke out GeorgeWestinghouse entered the army as avolunteer but afterwards exchanged tothe navy, where he served till the endof the w:ar. Improved facilities for stop-ping railroad trains had been occupyinghis mind for years, and his ideas cul-minated in 1868 when he secured a patenton what was known as the straight airbrake. That was a great step in theproper direction, but the compressed airwas conveyed direct from the engine to the various brake cylinders under thecars, which did not provide against acci-dents. When any accident happened tothe train pipe under that system the brakewas rendered useless. Mr. Westinghouse recognizing that de-fect proceeded to invent the mechanismnecessary to render the air brake auto-matic. The acting principle of this im-provement was the triple valve. To thewriter this triple valve was the most amaz-ing invention he had ever known. A com-.

Any accident which fractures thetrain pipe, serves to apply all the brakeson the train automatically. Designing the automatic brake was agreat feat of inventive genius, but manyother important improvements were madeby Mr. Westinghouse which enables thebrake to control or stop a 70-car train as smoothly as it does the local of S-cars.But Mr. Westinghouse did not confinehimself to brake mechanism. Every ap-paratus calculated to promote safety inrailroad operation received his attention.He also worked successfully in the elec-trical field and one of his latest achieve-ments was a geared turbine system forthe propulsion of ships.
