Cross-Section of an Inventive Design by Lewis H. Latimer (1899)
Drawing
This is a hand-drawn technical sketch by Lewis H. Latimer, dated 1899. The diagram appears to depict a cross-sectional view of a mechanical or electrical device, potentially a lightbulb filament housing or an electrical component. The drawing shows an internal structure, possibly indicating:
A protective casing surrounding a central filament or conductor.
A threaded attachment or screw base at the bottom.
Internal reinforcements or supporting elements.
Latimer’s signature is clearly present at the bottom, reinforcing authenticity.
Lewis H. Latimer was a pioneering Black inventor and engineer in the late 19th and early 20th centuries, primarily known for his contributions to electric lighting technology. His innovations in carbon filament lightbulbs were part of the effort to improve the efficiency and longevity of early electric lighting designs. This 1899 drawing represents Latimer’s continued engineering advancements, possibly connected to his work with General Electric or other electrical innovations.
