Sloan's constructive architecture; a guide to the practical builder and mechanic. In which is contained a series of designs for domes, roofs and spires ..
A practical builders' manual by Samuel Sloan, published in Philadelphia in 1859, meant for carpenters, builders and mechanics working on roofs, domes and spires. Its plates show roof trusses and framing diagrams, joinery such as panelled doors and window sashes, classical cornice and column details, and rows of tonal profile curves. A designer could draw on the crisp grey-shaded line drawings for architectural diagrams, and on the warm painted door panels for period woodwork.
