Historical Electrostatic Generator Diagram - Labeled Scientific Instrument #235221 (License: Personal Use)

This black-and-white engraved illustration depicts a classic electrostatic generator, likely from the late 1800s, designed to produce high-voltage static electricity via friction or induction. Key elements include paired rotating insulating cylinders (A and B), metal sectors (C and D), collecting combs (E), and grounding terminals (N, P), all mounted on a sturdy wooden frame with precision-adjustable knobs (H, M). The labeling (A-S) suggests its use in instructional texts or patent documentation.

Commonly used in educational textbooks, museum exhibits, or historical science archives to explain early electrical experimentation; targets users researching 19th-century physics instruments, antique scientific equipment, or STEM pedagogy history.
