Happy 175th, U.S. Patent No. 1

July 13, 2011 was the 175th anniversary of the granting of U.S. patent no. 1, issued to Senator John Ruggles of Thomaston, Maine. Senator Ruggles was chair of the Committee on Patents and the Patent Office and the chief framer of the 1836 Patent Act, which came into force on July 4. The Act abolished the old patent registration system that had been in force since 1793 and re-introduced an examination system based on novelty and non-obviousness. Senator Ruggle's invention was a wheel traction system for steam locomotives. It has been cited in several patents including US 6,725,751, issued in 2004 for a "rotary punching apparatus".

Patent Models Index

The Smithsonian has published new guide and index to patent models owned by the National Museum of American History. The two volume work is available for free online and can also be purchased in hard copy from the Smithsonian Institution Press. Volume 1 provides listings by patent number and title of the invention. Volume 2 contains listings by inventor name and residence. A great resource for fans and collectors of 19th century patent models.

New Book: Mr. Gatling's Terrible Marvel

This is library conference season, so I've been racking up frequently flyer miles by the thousands. Air travel isn't as fun for me as it was pre 9/11, but spending hours in the air does give me an opportunity to catch up on my reading. On my most recent flight I finished Mr. Gatling's Terrible Marvel: The Gun that Changed Everything and the Misunderstood Genius who Invented It by Pulitzer Prize-winning writer Julia Keller. The book is a biography of Dr. Richard Jordan Gatling and his most famous invention, the Gatling Gun, the first practical machine gun. (See the Economist review, "A Little Gatling Music.")

Strangely enough, Gatling claimed to have invented his machine gun in order to mitigate the pain and suffering caused by war. His reasoning, so he claimed, was that a rapid-firing weapon would require much fewer soldiers, thus reducing the size of armies and the number of battlefield casualties. Keller does a good job of capturing the essence of life in 19th century America, with all its energy, contradictions, noise and (even) odors. Central to her story is the idea that the U.S. patent system made it possible for amateurs like Gatling to drive economic development and social change farther and faster than ever before.

The book contains several factual errors and omissions. For example, Keller states that Samuel Hopkins, the first American inventor to be granted a patent under the new federal patent law in 1790, was from Pittsfield, Vermont. In fact, Hopkins was born in Maryland to Quaker parents and was a resident of Philadelphia for most of his life. (Journal of the Patent and Trademark Office, March 1998) And Although Keller mentions Gatling's many other patented inventions (his first successful invention was a seed planter patented in 1844), she provides the patent numbers for only a few: Nos. 3,581, 36,836 and 47,631). According to a Wikipedia article, Gatling's lifetime total was nearly 50 patents. It's interesting to note that searching Gatling's name in Google Patents retrieves only 12 patents.

Searching 19th Century Patents

During a recent visit to the Shelburne Museum in Vermont, I snapped this photo of a handsome iron matchbox on display in the museum's 19th century general store. The cover is embossed with a hunting scene... a dog carrying a duck.

It wasn't clear to me when the matchbox was made, but the text "PATD JAN 21 1862" suggests that the design was patented on January 21, 1862. It was common practice in the 19th century to include the date of issue but not the patent number on patented products, especially articles of manufacture. Fortunately, it is possible to retrieve early U.S. patents from the USPTO database by date of issue and a search (isd/18620121) retrieves some 50 patents issued on Jan. 21, 1862. Flipping through the first ten or so hits, I was able to quickly locate patent no. 34,230, an "improved box for matches" patented by Henry Howson of Philadelphia and assigned to W. F. Warburton. However, the drawings seemed to me to be very different to the finished article. Might there be a later patent? I zipped over to Google Patents and searched "Henry Howson" and found patent no. 39,994 issued on Sept. 15, 1863. The drawings and description in this patent more closely resemble the matchbox above. Howson also cites his 1862 patent. This is a good example of how to trace 19th century patents and why it's never safe to assume that the date embossed on an article of manufacture corresponds to the final patent. It's always wise to check for later improvements.
