Triumph MotorCycle Patents Veteran Motorcycle

In researching and learning about my veteran Triumph I have come accross various patents filed by Triumph and thought I would put them into date order. The Patent numbers stamped on the bikes and mentioned in the period literature will be as they were recorded in the period so in 1914 the patent Triumph carb. was just recorded as 24214 and now gets recorded with the country initials and year ahead of the number. As an example in 1914 Triumph patented a new carb as Patent 24214 and now it is recorded as Patent Application number: GBD 191424214 December 17th 1914. In the 1914 era it would have just been recorded as 24214 and now it has had the GB and year code added to the front of it. Accordingly you ideally need to the know the year the item was patented to be able to track down its paperwork, though this is helped by Triumph listing the patent year after a "/" in its literature. You should be able to get a full copy of the patent from your patent office.

I am not an expert in Veteran Triumphs, so should highlight that just because Triumph patented something it does not mean it was fitted to production bikes in the year or was even available to the public. Many of them were though, as they have their patent numbers proudly mentioned by Triumph in period literature. I suspect that they would have made at least one of whatever they patented to see how it worked. The date (day/month) it was patented is generally mentioned in the associated text.

1905

Patent 12007 - Variable speed gearing and clutch. Seems quite advanced for 1905.

Patent 12165 - Spring Fork

When Ixion rode a 1905 Triumph in June 05 he described the spring fork as new, though the pictures seem to show that the spring worked the other way round to this picture.
You can see details of Ixion's 1905 ride on the 1905 Triumph pages. In the 1914 Triumph literature they still mention this patent for the 1914 model bikes, even though the 1914 forks seem quite different to the picture below - especially how the spring operates.
