BRAMAH'S LOCK
Over the centuries the county of Yorkshire in the north of
England has produced some very famous people.
The Bront ë sisters, Captain Cook the explorer, William Wilberforce
and Chippendale the brilliant furniture maker, to name but a few.
But there is
another Yorkshire man, a prolific inventor, who is considered a
credit to his county even today, some 200 years after his death.
His name was
Joseph Bramah, a farmer’s son, born in 1748. His clever invention is
still used today – the Bramah Lock.
This was not his
only inspiration as he also invented beer-pumps, a water closet, and
a machine for numbering banknotes.
Bramah also
invented the hydraulic press and a machine for producing aerated
water, and suggested that the locomotion of a ship could be improved
by means of ‘screws’ in 1785!
In 1773 Bramah
walked the 170 miles from Yorkshire to London to seek his fortune.
Things certainly started to improve when in 1784 he patented his new
idea for a locking mechanism.
This lock caused
a stir, as it was a revolution (intentional pun!) in safety
measures.
Until this date
any lock, cheap or costly, could be ‘picked’ by anyone with only a
modicum of skill.
Bramah declared
that his barrel-shaped lock with its 494 million possible
combinations of notches was burglarproof. He was so
confident that he offered a 200-guinea prize to the first person who
could ‘pick-it’.
The prize went
unclaimed for 67 years until an American locksmith, Alfred Charles
Hobbs, finally managed to pick the lock after a month’s hard work.
Nevertheless,
the design was so effective that the Bramah Lock, with certain
variations on its design, is still used today.

Joseph Bramah's signature is the
trademark of the Bramah Company who manufacture locks to this day.
