Carbon Conductor, (1 folder, 1881)
Archive
Lewis Latimer officially witnessed (and probably drew) this carbon manufacturing process patented by his boss, Hiram Maxim. Latimer worked closely with Maxim in Bridgeport, Connecticut, and New York City between 1879 and 1881, “acquainting myself with every branch of electric incandescent light construction and operation,” as he later wrote. Latimer most likely contributed to patents that bore Maxim’s name.
This set consists of patent documents and illustrations, some of which show signs of damage, including frayed edges and taped repairs. One sheet contains a technical drawing of a mechanical system with labeled components. Other documents feature dense text outlining the claims and protections granted by the patents. These historical materials highlight engineering advancements and Latimer’s contributions to industrial and technological development.
These documents are part of the U.S. Patent Office collection and pertain to patented inventions from the late 19th and early 20th centuries. The materials include official patent descriptions, claim statements, and technical schematics, possibly associated with Lewis H. Latimer’s engineering work.
