Total article view: 755

The credit of Inventing cylinder pin-tumbler lock goes to Linus Yale, Junior. His locks are still widely used by us. Yale's father, Linus Yale, had invented (patent : an earlier pin-tumbler lock in 13 June 1844. Mr. Linus Yale, Sr. opened a lock shop in the 1840s in Newport, NY, specializing in bank locks. His son soon joined him and introduced some revolutionary locks. In 1858, Yale’s father died, and Linus Yale, Jr. became more involved with his father’s lock company.



The pin tumbler lock or Yale lock is a lock mechanism that uses pins of varying lengths to prevent the lock from opening without the correct key. Although Yale had the credit of inventing the pin-tumbler lock but the basic principles of the pin tumbler lock may date as far back as 2000 BC in Egypt.


Yale Jr.

In 1851, Yale patented a pin tumbler lock for use in banks, in 1863 he patented his pin tumbler lock for use in doors and in 1865 he patented the pin tumbler padlock, which we still widely in use today in car doors and the outside doors of buildings. His lock used a smaller, flat key with serrated edges. In 1868, Yale and Henry Robinson Towne founded the Yale Lock Manufacturing Company in Stamford, Connecticut, to produce cylinder locks. He dies in the same year due to a sudden heart attack. In 2006, he was inducted in National Inventors Hall of Fame.
