Abridged Patents 1877-1930 Class 7 Air & Gas Engines

The United Kingdom Patent Office organised its early publications by 'Class' number, so that for a given subject there would be a matching Class or group. Within these Classes or groups there were generated a brief precis of the original Patent called an Abridged Patent. This was then published in sets of volumes for each Class. We have a set of the Class 7 Abridged Patents (Air & Gas Engines) covering 1877 to 1930, which includes the Subject and Names Indices of the Patentees.

The Class Index gives a complete listing of ALL Patent classes, and is included below.

To better display the whole set, we have had to break each year into sections, otherwise the website would have problems with handling a single folder with 7930 pages of HTML and the scanned image of the pages. Most of the years or sections will go into a single folder, but a couple will be split across more than one folder.

THESE SECTIONS ARE NOT OPERATIONAL YET!
