lock shop in the early 1840s in the village of Newport, New York, specializing in bank locks for bank vaults. In 1850 his son, Linus Yale Jr. joined him at the lock shop and began working on improving his father's pin tumbler lock. Linus Yale Jr. would later found the Yale Lock Company with Henry R. Towne, which would end up becoming the premier lock manufacturer in the United States. They would later add the manufacturing of chain blocks, electric hoists, cranes and testing machines, and become the pioneer of crane builder. Through his career as an inventor, Linus Yale Sr. registered 14 patents under his name at the United States Patent and Trademark Office, and were signed by the President of the United States Andrew Jackson. These patents included innovations about a threshing machine, sawmill head block, combination lock, pin tumbler safe lock, bank lock, vault and safe door bolt, among others. The innovations made in the gun-making industry were useful for the door lock industry, as gun locks and door locks were similar in design. After the civil war, the factories stopped manufacturing weapons and started using their capacities to manufacture others products such as sewing machines, bicycles, factory-canned foods, home appliances, and automobiles. The knowledge gained through the war effort was thus very useful for the Yale Lock Company as each part of the lock system was designed to allow its manufacture with machine tools, just like the concept of the precise-machine tools of interchangeable parts used by his brother Allen Yale at LG & Yale during the war. Family Around 1850, Linus Sr. built an octagon house for the marriage of his daughter, Chlothilda to Ira L. Cady. The building is now listed on the National register of Historic Places. Just as his son, Linus Yale Jr., his grandchildren would be part of the industrial revolution as well. Catherine Brooks, Linus Yale Jr.'s wife, was born in into an elite family. She was the daughter of John Brooks, a doctor and member of the Legislature. His grandson was the Governor of Wyoming Bryant Butler Brooks, and his cousin was the Bishop of Massachusetts Phillips Brooks. Catherine's favorite teacher was the famous Ralph Waldo Emerson, who was from Massachusetts as well. Her sister, Jean Brooks Greenleaf, was also married to Congressman Halbert S. Greenleaf, and was elected President of the New York State Women's Suffrage Association. Madeline
