How Modern Locks Were Improved Over Time

By Shirley Clark


Residences are not safe and secure without security bolts on the door. This will make the home inaccessible to anyone who will attempt to intrude it. It keeps the occupants and the objects inside safe from illegal entry and home invasion. This system is designed to thwart any effort from unauthorized access of valuables inside a house. You can have your doors locked very securely with systems from Locksmith Victorville CA.

The science of making secured hasps has no written history. There is substantial proof though that these were already in use during the ancient times. Excavated materials from Rome, Greece, and Egypt have given proof to its existence. These are very few of these however, contingent on the material it was made of and the climate which affects it.

One of the first ever made was to be found in a Persian palace belonging to Sargon II. It was of Egyptian origin and used the same principles that are still used today. This was a combination of the cross beam with tumblers horizontally placed on vertical mounts across the inner door and could only be opened by a key. The cross beam was usually hollowed out and intersected with the vertical one that has tumblers.

The great epic poem Iliad has a passage that mentions the Gordian knot. This is a testament to the wide use of rope during that time. It was used to secure anything and the art of knot tying became an elaborate art. This was the time when Greek houses had doors that pivoted at the middle and the ends were fastened with ropes that were tied in knots.

The Romans improved on this by utilizing the first notched bolt assembly. This design made use of metals like iron and bronze which encased the mechanisms and also used metals as keys. As is always the case with metals, these are subject to corrosion and rust resulting in keys being made as jewelry extensions in the form of rings and necklace attachments.

They, the Romans are also said to be the inventors of the padlock, though there is evidence that the Chinese also had this kind of item dating back before or during the time of the Romans which means that these developed at about the same time in two different regions. The use of security hasps declined in use after the fall of Rome as there was little property to protect.

The middle ages saw this security mechanism regain prominence especially among the wealthy citizens of the well populated city centers in Europe. The principle used was still the same as those that were made in olden times. However, these were now built with very ornate designs. The assemblies had movable bolts that could be manipulated with keys.

The modern assemblies of today are mostly attributed to the guilds in England that sponsored contests in lock making. Three men, in particular, are credited with what we have today. One of them devised a double acting combination that was very hard to unravel compared with the others. He patented his tumbler and ward combination which is the forerunner of modern day locks.

Modern locksmiths use advanced technology in the manufacture of locking mechanisms. It is widely used in almost anything that will be made as a repository of materials. Work desks, cabinets, cars, houses all have some mechanism to protect it against unauthorized use or entry. Modern smart homes are now equipped with security systems that include automatic security locks.
