Helical Compression Spring Diagram - Engineering Illustration #61059 (License: Personal Use)

This black-and-white engraved illustration shows a vertically oriented helical compression spring with consistent coil spacing and tapered ends. The fine cross-hatching adds texture and dimensionality, typical of 19th- or early 20th-century technical manuals. The arched frame suggests it was originally part of a larger schematic or textbook plate.
