I am looking for a means to confirm that Frederick Huston Evans was the or an inventor of dental bur-making machinery. I found the following in the Who's Who of Engineers 1922-23:

I have found his text book but can find no further information on him being an inventor of dental bur-making machinery. I was able to fint that Ransom & Randolph Co is/was involved in making equipment for the dental industry.
Thank you in advance.
