system.
Since most early inventors were ordinary people without technological or legal training, it was difficult for them to submit formal patent applications which require the novel features of an invention to be described using words and a number of diagrams. Actually, the patent system then was very crude by today's standards. It was a good idea for these amateur inventors to submit a model with a brief explanation or drawing of it.

). Although he intended to establish a patent model museum, the stock market crash of 1929 damaged his fortune; the models were left in storage. After his death, the collection went through a number of ownership changes; a large portion of the collection—along with $1,000,000—was donated to the nonprofit United States Patent Model Foundation by Cliff Peterson. Rather than being put into a museum, these models were slowly sold off by the foundation. A saga of legal wrangling, purchasing, and re-selling ensued. A comparatively small number of models (4,000) are currently the property of the Rothschild Patent Museum.
