Richey's guide and assistant for carpenters and mechanics : a work of practical information, giving almost every geometrical and practical problem likely to arise in the work of the carpenter, and quick and easy methods for their solution : the use of the steel square, etc., tables showing strength and weight of materials, methods of framing, useful recipes, etc., etc.
A trade manual for carpenters and mechanics by Harry Grant Richey, published in New York by W. T. Comstock in 1894, collecting geometrical constructions, steel-square methods, framing layouts and tables of material strength for working builders. The plates are numbered line diagrams: arcs, chords, tangents and hipped-roof projections drawn in fine black rule with dashed construction lines and italic letter keys, useful as ready-made geometric linework, technical ornament, or diagram texture.
