When locked, the discs passed through cut-outs on the shackle. Each disk had a central cutout to allow the key to pass through them and two notches cut out on the edge of the disc. These locks had a cast iron body that was loaded with a stack of rotating disks. Improved manufacturing methods allowed the manufacture of better padlocks that put an end to the Smokehouse around 1910.Īround the middle of the 19th century, "Scandinavian" style locks, or "Polhem locks", invented by the eponymous Swedish inventor Christopher Polhem, became a more secure alternative to the prevailing smokehouse and screw locks. Padlocks that offered more key variance were the demise of the screw lock. The key pulled the locking bolt open against a strong spring. Contemporary with the smokehouse padlocks and originating in the Slavic areas of Europe, "screw key" padlocks opened with a helical key that was threaded into the keyhole. These locks afforded little protection against forced and surreptitious entry. Smokehouse locks, designed in England, were formed from wrought iron sheet and employed simple lever and ward mechanisms. Padlocks with spring tine mechanisms have been found in York, England, at the Jorvik Viking settlement, dated 850 AD. The use of bronze was more prevalent for the early Chinese padlocks. Padlocks were made from bronze, brass, silver, and other materials. According to Hong-Sen Yan, director of the National Science and Technology Museum, early Chinese padlocks were mainly " key-operated locks with splitting springs, and partially keyless letter combination locks". Padlocks have been used in China since the late Eastern Han Dynasty (25–220 AD). Przeworsk and Chernyakhov padlocks had a sleeve attached to the case, and a long bent rod which could be inserted into the case and the sleeve. Roman padlocks had a long bent rod attached to the case, and a shorter piece which could be inserted into the case. Padlocks have been used in Europe since the middle La Tène period, subsequently spreading to the Roman world and the Przeworsk and Chernyakhov cultures. They were known in early times by merchants traveling the ancient trade routes to Asia, including China.
