paten #'s

Any idea how I can look up a paten # and see what purpose the object in question is supposed to serve? I found this tool in Colorado and I can’t figure out what it could possibly be. It does have a paten number on the side of it so I’m trying to identify it that way.

Thanks

When I was an altar boy, the patens I used didn’t have numbers on them. :slight_smile:
