Under Yale's ingenuity and wide promotion of his inventions, Yale Locks quickly spread around major corporations in the United States and were widely adopted. Among some of Yale's business tactics were exploiting the weaknesses in other locks and presenting how his were free of those vices; he did live demonstrations to corporate business executives and government officials that showed how he successfully picked the locks that were in operation. Due to these demonstrations and the sheer quality of Yale's locks, Yale Lock Manufacturing quickly gained business ground. The company's name was later changed to The Yale and Towne Manufacturing Company, which eventually became part of NACCO Industries.
