Mechanical Drawing Self-Taught / Comprising instructions in the selection and preparation of drawing instruments, elementary instruction in practical mechanical drawing; together with examples in simple geometry and elementary mechanism, including screw threads, gear wheels, mechanical motions, engines and boilers

A practical manual for beginners explains the selection, preparation, and use of drawing instruments and materials, emphasizing pencilling before inking and progressive construction of examples. It presents fundamental lines, curves, and geometric constructions (including ellipses, parabolas, and polygons), techniques for shading and sectioning, marking dimensions, and arranging multiple views and projections. Detailed guidance covers bolts, nuts, screw threads, spirals, and common workshop fittings, and offers worked exercises—scaled drawings and shop-ready examples such as springs, coupling rods, frames, engines, and boilers—to develop skill in creating accurate mechanical working drawings.
