Hobbs & Co's Patent Violence Protector Locks
The 'Violence' locks were so named because they focused on protecting against physical attack.
Hobbs had already, with their protector patents, dealt with the tentative methods of defeating a lock and were of course incorporated in the violence range of locks.
Additionally though a host of other features specially designed to thwart determined physical attacks made for a very effective system to prevent violent entry.
This included attacks by gunpowder, drilling and chemical solvents.
In the companyís own words - "To destroy the holding power of these locks (even with engineering tools specially designed for the purpose) would require more time and labour than any mechanic could surreptitiously secure to work on them."
Another feature with these locks is that the points of attack could not be determined, due to varitations in size and layout, from the outside of the safe door.
Its also worth noting that it was common to find a Violence lock used in conjunction with a normal Protector lock, or a change key lock, or even 2 Violence locks on the same door.
Locks with 'Violence' features, or 'Ant-Violence' as they became known as, were made in various sizes from 5" (132mm) up to a gigantic 60" (1524mm) and with up to 15 levers.
