I have an aguilette - the metal tube that goes on the end of a dress cord - on a military uniform. Stamped on it is "Knaps Patent"  and "Jan. 6, 1827". Can anyone tell me what this Knaps patent is ?  Thanks, steve in so az

I don't know that patent off the top of my head, but here's how I'd find it if I had the time:
I'd search for patents issuing on January 6, 1827.  Unfortunately, patents prior to 1976 are not searchable by issue date -- only by patent number and/or classification.  So, you'd have to do some detective work.  Start with a patent number around 200,000 and see if it issued before or after Jan. 6, 1827.  You'll have to access the patent images to determine the issue date.
Then, try either 150,000 or 300,000 or 1,000,000 or whatever number is suggested by the direction and distance of the issue date of patent 200,000.  Soon, you'll realize that a couple hundred patents issued on the same day.  All I can suggest is looking at them one by one until you see one whose first named inventor has the last name Knaps.  That's probably your patent.
You can narrow this process down a bit by determining the proper US classification for that particular article.  There should be information regarding invention classification at
I hope that helps.
