Newly Found Patent?

Submitted by Brian R. on Mon, 02/25/2019 - 10:46

I was working on my c.1920 CCM Cleveland 458 mens, serial number 101294, and found a patent stamp that I have never seen before. It's located at the top of the fender brace, both front and rear, where the brace meets the fender, and it says:

PAT. MAY 14, 1918

I tried the Canadian and US patent office search engines without any luck and with much frustration. Their search engines are very cumbersome and complicated to use. I found nothing on Google Patents, and it's not listed in the Appendix of CCM patents at the rear of John McKenty's book.

I also tried searching this site for any reference to this patent and found nothing. So, I'm wondering if anyone else has seen this before, and if anyone here knows anything about this patent. In addition to looking at 1917-1920 serial numbers, it could potentially be a useful tool for helping to put a year to these bikes that have Weston badges but no letter code in the serial number. The idea being bikes with this stamp are probably 1919-1920 models and bikes without this stamp are likely 1917-1918 models.

If the patent is referring to the design of the fender brace, then maybe we can find a bike with pre 1918 braces (whatever was used before this one with the stamp) and post a photo here for reference. I will post a photo of the stamp and one showing the fender and brace with the stamp.

Thank you for finding that! I had searched for fender backet instead of mudguard brace! So it turns out to be a US patent, by one Walter Green of Chicago. I have no doubt it's the correct patent, but oddly it seems to be limited to an attachment of the ends of double braces where the two braces meet the axle, whereas my CCM Cleveland with this patent stamp has single braces. In other words, my bike is not even making use of the patent for which it carries the stamp.
