The new metal worker pattern book; a complete course of instruction in the modern methods of developing and cutting the patterns for sheet metal work, giving the principles under-lying practically every problem that is likely to come up in practice and explaining the selection and use of drawing tools and linear and geometrical drawing so clearly that one who has had no previous knowledge of arithmentic or drawing, may understand these essentials and apply them in using the 253 problems in the development of patterns by the parallel line, conical or flaring, and irregular or triangulation systems
