FIG.4 Mechanical Assembly Diagram - Patent Illustration of Linked Components #1471783 (License: Personal Use)

This black-and-white technical drawing depicts a complex mechanical linkage system, with components A through J indicating rollers, levers, pivots, and housing structures. Shading denotes solid cross-sections, while lines show connections and potential movement axes-common in patent filings for devices involving rotational or translational motion. The lower inset shows a close-up of a bearing or cam interface (H).

Used in patent documentation, engineering manuals, or academic papers to clarify device mechanics; targets inventors, patent attorneys, and mechanical designers seeking prior art or functional understanding.
