Wooden Folding Ruler or Angle Gauge
Object/Artifact
A wooden measuring tool with two pivoting arms connected by a circular brass hinge. The device allows for the measurement and replication of angles. The dark wood and brass fittings suggest it is an older or vintage tool, likely used in engineering, carpentry, or drafting.

This type of instrument was commonly used by engineers, architects, and carpenters for measuring and transferring angles accurately. Given Lewis Latimer’s work in engineering and drafting, this tool may have been part of his personal or professional collection, possibly aiding in his technical drawings and inventions.
