YALE
LOCK
Introduction:
In 1861, Yale Jr.
designed the cylinder pin tumbler lock, which was a lot less weight than his
father design and could be opened with smaller keys. His father Mr. Linus Yale
designed a lock system which was wooden and bulky.
Working of Lock system:
Yale Jr. lock works, when
a key inserted into the cylinder lock, it pushes the bottom set of pins into alignment,
when key matches to lock then all set of pins perfectly insert into the
serrated edges to the key. Lock consists of two jaws, one holding all the set
of pins with spring action to enter into key jaw. Key easily enters into key
jaw when it matches, all the pins in the second jaw perfectly come out of it
into key jaw in a plane alignment. When the key rotates, key jaw itself rotates
to unlock the system, i.e, all pins align over the jock to unlock the lock.
These locks were
amenable to mass production with affordable price.
