Blueprint of Telegraph Pole Wiring System (September 1889)

Drawing
This is a blueprint of a telegraph or electrical power pole wiring system, dated September 1889. The technical drawing details the structure of a wooden utility pole with multiple crossbars supporting numerous insulators and wires, systematically arranged to illustrate the electrical wiring configuration. The image showcases an early example of infrastructure used for communication or electrical distribution during the late 19th century. The precision of the drawing suggests it was created for engineering or patent documentation purposes.

This blueprint is attributed to Lewis Howard Latimer, a pioneering Black inventor and engineer who significantly contributed to the development of electrical lighting and telecommunications. Latimer worked closely with Alexander Graham Bell and Thomas Edison, playing a key role in refining carbon filament lightbulbs and drafting technical patents. This document, dated 1889, likely represents a period when Latimer was involved in designing electrical and communication infrastructure, a crucial step in expanding electrification and telecommunications in the U.S. During the late 19th century, the expansion of electrical grids and telegraph networks was vital for industrial and commercial progress. Blueprints like this were essential tools for engineers, serving as schematics for constructing efficient and scalable systems.
