ever come across one of these and wonder what it's all about?

in some cases, they can tell you a lot about the machine they're attached to. this particular plate indicates that the inventor received patent number 908359 for some aspect of the attached machine on December 29 of 1908.

you can see any original patent document, including the drawings and description of the invention, the inventor's name, location, the company he worked for, etc. by typing the patent number at the following website:

(in this case type "908359")

so, what does this plate belong to boys?
