Research Resources: British Patents

Looking through old British patents is not nearly as easy, in some respects, to US Patents. With the right index, they are easily searched by subject, but to get any detail, even the abstract, you need to go to the British Archives. If someone knows of an online resource to see details behind any of these patents, please let me know.

Right now I’m focused on British patents up to about 1860, but have some of the indices for some later years in the 19th-century.

Up to 1852 (October, to be exact), British patents used a sequential numbering system. After October of 1852, the numbers became a mixture of year and number, e.g. 18631202 for Patent 1202 from the year 1863.

Fortunately, Google Books has several of the indices. Unfortunately, it’s Google Books, so there’s no way to find a single list of the same title. You have to search for them and use “related books” links etc… Google puts too much trust in search.

So, I’ve put together a list of the useful volumes I’ve been able to find. I’ll add to the list as I find things or people point me to missing volumes.

Main Index by Patent Number.

There is a two-volume index for the patents up to Oct. 1852. Volume 1 goes up to 1823, and Volume 2 continues from there through patent 14,359 in Oct. 1852.

This index is useful if you have the patent numbers. For my purposes, the best way to find them is by subject indices.

Subject Matter Index

The subject matter index for up to 1852 is also in two volumes. Volume 1 is for subjects beginning with a-m. Volume 2 is for subjects beginning with n-w. I’ve not found Volume 3 yet.

Pens, pencils, etc… are listed under “Stationery” so they are found in Volume 2.

After 1852, the subject matter indices are listed by year. I’ve so far been able to find the individual indices for the rest of 1852 (Oct-Dec) – 1869 with the exception of 1862, and 1865.  Then I found the index for 1881, but nothing between 1865 and 1881. Obviously there’s much more to find and I’ll update as I find more.

So, here are the indices for 1852 onward. In each book, look in the list at the front to find the page number for pens, pencils, etc…  On that page you’ll find a subject of the patent, the number, date and patentees.

Descriptions of the patents, up to 1866

I was able to find the volume with the abridged specifications of each patent from 1635-1866 related to Writing Instruments and Materials. This is the Holy Grail resource for these early patents as most British patent specifications are only available if they’ve been printed in a journal or some other source. It doesn’t include pictures, but it at least will give you enough of an idea if it’s worth looking for. It also provides contemporary sources where this patent was published.
