Abstract: A pattern duplicating apparatus including a large rigid frame suspended by trolleys from an I-beam and carrying longitudinally spaced tracer and cutter assemblies. The frame is manually displaceable linearly in the longitudinal and vertical directions and pivotally about the longitudinal axis. The frame suspension includes interconnected sprockets and chains to ensure a pure rectilinear vertical displacement.
