An Original American Patent Model Offering
circa 1836-1890s
From US PATENT MODEL FOUNDATION GALLERIES

Submitted by its hopeful inventor, this is the actual model that 19th century patent examiners relied upon to award a patent. Each one-of-a-kind patent model is from the original U.S. Patent Office collections circa 1836 - late 1800s when inventors had to submit models with their patent applications. To conserve space, they were to be no more than 12 inches square. Each model represents a specific, patented invention, identified by its own patent number, and is the only such one in existence. Today, these diminutive models are seen mostly in private collections and prestigious institutions such as the Smithsonian, and are highly prized by astute collectors worldwide. If you aren’t familiar with patent models (sometimes confused with salesmen samples) scroll to the bottom of the page to learn about these curious, one-of-a-kind icons of 19th century American ingenuity.

Each model comes with a Certificate of Authenticity and parchment copies of its patent and claims suitable for framing. As with any historical item from the 1800’s, signs of age and wear are common and are considered part of a model’s charm.

Please review item carefully and ask us any questions before bidding, as items are not returnable unless not as described.

“This invention relates to certain improvements in metallic thimbles for ropes and cordage, and to the method of manufacturing the same.

U.S. PATENT MODELS – 1836 TO NOW

A Patent Model is the actual invention prototype, which, by law, an inventor was once required to submit to the U.S. Patent Office, in Washington, when seeking a patent. The law stated that the model was to be no larger than 12 inches square, thus patent models are all miniature devices, which greatly adds to their appeal.
These models were required for a little more than a half-century, circa 1836 to approximately 1890. Models were sent with patent drawings and specifications, which included the inventor's claims stating why the idea was new.
