Vintage Steam Engine Schematic Diagram - Industrial Machinery Blueprint #117357 (License: Personal Use)

This black-and-white engineering diagram illustrates a complex horizontal steam engine, featuring a flywheel, cylinder with piston (L), valve gear (K), condenser (I), and multiple pressure gauges (H, P, C). Annotations identify critical parts such as the governor (U), steam chest (M), and exhaust system (O), offering insight into early industrial power generation. The drawing reflects precision drafting standards of late 19th- or early 20th-century mechanical journals.

Used in educational resources, museum exhibits, or historical engineering articles to explain steam engine operation; targets students, historians, and mechanical engineers seeking archival technical references.
