notes: label: Description (Brief)
content: Model for US Patent 910, "Apparatus for the Application of Electromagnetism as a Motive Power," issued 12 September 1838, to Solomon Stimpson, filed 23 July 1838. This unit shows features similar to Moritz von Jacobi's work in 1834. Stimpson's patent issued the year after Thomas Davenport's patent (#132), based on work also done in 1834. In 1837 and 1838, Davenport and Ransom Cook were demonstrating their motors in New York City. Stimpson, a resident of NYC, almost certainly saw one of those demonstrations. His work is most likely an attempt to improve on Davenport's and Jacobi's designs.
