The Patents of George Westinghouse
A pioneering inventor whose innovations revolutionized railroads, natural gas, and electricity, George Westinghouse was issued 360 U.S. patents. The Westinghouse Legacy has assembled this unique chronicle of his patents, reflecting the impact he had on both history and the modern world.
U S Patent 5525 for Steam-Powered-Brake Device
The interactive list below includes every patent registered by the U.S. Patent and Trademark Office to George Westinghouse as the inventor.
The list is generally organized chronologically according to the patent’s issue date, which could be months or even years after it was filed. In fact, the final eighteen patents on the list were issued after Westinghouse’s death on March 26, 1914.
Our list was drawn from A Biography of George Westinghouse, published in 1921 by Henry G. Prout, an engineer and close associate of his for many decades. In an Appendix of his book, reproduced below, Prout lists each patent issued to George Westinghouse. Our compilation also relied on Google Patents, which archives patents from around the world.
You can scroll through the interactive list below to gain insight into the working processes of Westinghouse’s creative yet practical mind, not to mention his skill as a draftsman.
