- Description of Pictures: Invention and the Patent Model
June 20, 2013 – April 20, 2014
Between 1790 and 1880, the U.S. Patent Office required a three-dimensional working model of each submission to demonstrate how the invention worked and to compare it against previously patented inventions. The models reflect technological needs during the 19th century, as well as the social roles and division of labor between men and women. This case highlights 20 models from the museum’s collections, including the model for Samuel Morse's telegraph patent.
- Recognize anyone? If you recognize specific folks (or other stuff) and I haven't labeled them, please identify them for the world. Click the little pencil icon
underneath the file name (just above the picture). Spammers need not apply.
- Copyrights: All pictures were taken by amateur photographer Bruce Guthrie (me!) who retains copyright on them. Free for non-commercial use with attribution. See the [Creative Commons] definition of what this means. "Photos (c) Bruce Guthrie" is fine for attribution. (Commercial use folks including AI scrapers can of course contact me.) Feel free to use in publications and pages with attribution but you don't have permission to sell the photos themselves. A free copy of any printed publication using any photographs is requested. Descriptive text, if any, is from a mixture of sources, quite frequently from signs at the location or from official web sites; copyrights, if any, are retained by their original owners.

I love well-behaved spiders! They are, in fact, how most people find my site. Unfortunately, my network has a limited bandwidth and pictures take up bandwidth. Spiders ask for lots and lots of pages and chew up lots and lots of bandwidth which slows things down considerably for regular folk. To counter this, you'll see all the text on the page but the images are being suppressed. Also, some system options like merges are being blocked for you.
Note: Permission is NOT granted for spiders, robots, etc to use the site for AI-generation purposes. I'm sure you're thrilled by your ability to make revenue from my work but there's nothing in that for my human users or for me.
If you are in fact human, please email me at guthrie.bruce@gmail.com and I can check if your designation was made in error. Given your number of hits, that's unlikely but what the hell.

- Specific picture descriptions: Photos above with "i" icons next to the bracketed sequence numbers (e.g. "[1] ") are described as follows:
- SIAHPA_131214_02.JPG: Sewing machine patent model, 1870
This model, made to accompany William T. Smith's application for a patent (No. 99,743), is beautifully decorated -- far beyond Patent Office requirements.
- SIAHPA_131214_12.JPG: Toaster, 1930s
Manufacturers employ industrial designers to make products more enticing. The style of this otherwise commonplace toaster was influenced by the 1925 Exposition of Decorative Arts in Paris.
- SIAHPA_131214_16.JPG: Presentation vase, 1893
This silver Tiffany vase features the Transportation Building that architect Louis Sullivan designed for the 1893 World's Columbian Exposition in Chicago.
- SIAHPA_131214_24.JPG: Cannon, 1864
John Ericsson, Swedish American
Ericsson's improvement in the construction of "Ordnance" was one of may inventive achievements, including the design for the battleship USS Monitor during the American Civil War.
- SIAHPA_131214_31.JPG: Telegraph, 1846
Samuel FB Morse, Massachusetts
Morse is renowned for his telegraph. This relay, a component of his model for an "Improvement in Electro-Magnetic Telegraphs," enabled the transmittal of a current over long distances. Morse developed the code used with this system.

- Bigger photos? To save server space, the full-sized versions of these images have either not been loaded to the server or have been removed from the server. (Only some pages are loaded with full-sized images and those usually get removed after three months.)
I still have them though. If you want me to email them to you, please send an email to guthrie.bruce@gmail.com
and I can email them to you, or, depending on the number of images, just repost the page again will the full-sized images.
- Connection Not Secure messages? Those warnings you get from your browser about this site not having secure connections worry some people. This means this site does not have SSL installed (the link is http:, not https:). That's bad if you're entering credit card numbers, passwords, or other personal information. But this site doesn't collect any personal information so SSL is not necessary. Life's good!
