All mechanical patents were formally written and published in patent books in the year in which they were registered. Copies of these books can be found at a handful of libraries in the UK. This mechanical patent was originally searched at the Business and Intellectual Property Centre of the British Library in London in April/May2013. However, this library was unable to make copies at that time because the books in their collection were in a fragile state. Instead, copies were obtained from the reference desk at the British Library in Sheffield. Details regarding how the original patent research was accomplished in 2013 can be found at Patent/Design Representation Research. A PDF formated copy of this mechanical patent was discovered while visiting the Business and Intellectual Property Centre of the British Library in London in April/May 2015 and was added to this webpage in June 2015.
