Here’s a saw trademark of E. C. Atkins & Company’s, to prove that Disston wasn’t the only game in town. The pdf online of the registration certificate is corrupted, but the top half showing the logo is fine. Also legible is that
The trade mark is applied or affixed to the goods by etching into the body thereof.
I looked up the Patent Gazette for the registration date to find that it was published on March 27, 1928. I then looked up that Patent Gazette to get the details that they claimed use since May, 1865 and that is was for cross cut saws.
