Description: |
This patent was subsequently improved in patent GB-189,625,037, which is the only information we have on this patent: the latter patent mentions this patent as being improved upon, but to date we have not been able to find this patent online. Older British patents, especially those between about 1872 and 1900, are often not available online despite the patents of that era being particularly important in a variety of subjects including machine tools and electricity. The patent issue year is known but the exact patent issue date is a rough estimate. |
