Vintage Scientific Diagram: Fig. 1 Electrostatic Apparatus Schematic #1413335 (License: Personal Use)

This black-and-white engraved diagram, marked “Fig. 1,” depicts a vertically oriented scientific instrument featuring a top spherical terminal (A), a central rod (B), intersecting horizontal bars, and two feather-tipped arms (F and G) pivoted at E. At the base, cylindrical components (C, I, K) suggest grounding or charge storage elements, while the overall symmetry implies use in physics demonstrations involving force, equilibrium, or electricity. The style and labeling align with 18th- or 19th-century scientific publications.

Typically used in historical science education, museum exhibits, or academic articles discussing the evolution of electrostatic experiments (e.g., by Franklin, Coulomb, or Priestley). Matches user intent for researching vintage instrumentation, physics history, or sourcing public-domain illustrations for educational content.
