Wood pattern-making; the fundamental principles and elementary practice of the art
Horace Traiton Purfield's 1906 manual on wood pattern-making for foundry work, printed in Ypsilanti, Michigan, for trade students and apprentice patternmakers. The 133 line drawings show joints, cored blocks, bevel gauges and curved pipe patterns in dense hatched wood grain, with section cuts and lettered reference points—useful for grain textures, axonometric block diagrams and annotated construction details.
