Adjustable Metal Bracket Diagram - Engineering Drawing Reference #3724467 (License: Personal Use)

This black-and-white engineering line drawing depicts a mechanical bracket assembly featuring a vertical mounting plate with two bolt holes, a curved support arm, and a long horizontal bar marked 'A' with a circular end hole. The design includes a central pivot joint with a thumbscrew for angular adjustment and a top clamping mechanism for securing position. The clean drafting style suggests patent or technical manual origin.

Commonly used in historical patent documentation, restoration guides, or mechanical engineering education to illustrate adjustable support mechanisms for tools, signage, or equipment mounts; matches user intent for technical reference or vintage hardware identification.
