If the oldest found lock is 4,000 years old then it is evident that a locksmith
used to exist in the earliest of times. The locks created by him must not have been very technical, such as those that we find today, but they must have been serving the purpose intended. Keeping possessions and valuables safe has been one of the foremost intrests of man. Even if it was a simple hook stuck in a loop; there was a psychological relief attached with that act of a locksmith
. Locking things up before leaving homes has been almost a ritual especially in old fashioned people who do not trust the latest digital systems that can be tampered with. Lets take a look at the history of locksmithing in America.
Before 1800, over 80% of the iron locks and 90% of the brass locks for the country were imported. A locksmith in China had made a lock long before the American locksmith. The number of edges on the key and warps varied with the level of protection that was required of the lock. The key was everything. Although, locksmith in the colonies made locks for the country, they were not fulfilling demand as the country expanded. In Sagus, Mass were erected the first iron works industries of America and it was intended that one of the works that they would produce would be that of a locksmith. Still, the demands of the population were not being fulfilled.
As buildings grew, the type of doors made were the ones that were made by people in England. So the locksmith created locks that he had been familiar with, for these particular doors. Talking about handcrafting of locks by the locksmith, it ended in the 1840s. With the Industrial Revolution in happening, some famous producers set up industries only to produce door locks. Others were producing nails, screws, bolts and other items of the like during this time. A locksmith notable in this era wasn't just one; rather Seth North of North and Stanley; Henry Russell of Russell and Erwin and Philip Corbin of P&F Corbin had been the famous American locksmiths in those times.
Traditional locks took up a decorative form when Russell and Erwin began producing locks with a decorative rim. Between 1840 and 1900, patents were issued to hundreds of men who called themselves a locksmith. After Corbin developed the unit lock, the locksmith J.A Blake in 1833, developed a patent for the lock, off springs of which have become the tubular locks today. Later Mr.Walter in San Francisco was awarded 11 patents for the tubular lock. During this period a noticeable development was the use of the door knob on locks first introduced by Mr.Pepper in 1951. It was called The Mineral Knob. John Pepper consequently set up his own firm that made knobbed locks. In 1916, Samuel Segal, who was a policeman, developed a jimmy proof lock. To this day, we can find 25 patents listed in the name of this locksmith.
