U.K. Provisional Patent 1871-101
This provisional patent was registered by William Avery on January 14th, 1871. It appears to be a prelimiary patent to one
issued four months later (1871-1322) as many of the needle cases have the same descriptions in both patents. It covers the Alliance,
Britannia, Constance, Diana and all Revoling needle cases and consists four pages of text. This patent also includes drawings or
descriptions of eleven additional needle cases that appear not to have been manufactured as no needles cases like these have been
found. To review the details of this patent, select the appropriate page for the list below. Once the page is display, click

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. All of the mechanical patents available on this website were originally searched at the Business and Intellectual Property Centre of the British Library in London. However, this library was unable to make copies 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 patent research was accomplished can be found at Patent/Design Representation Research.
