Formulas in gearing, with practical suggestions
A machinists' handbook of gearing formulas and practical suggestions issued by Brown & Sharpe of Providence, Rhode Island, in 1892 for toolmakers, draftsmen and shop engineers. The plates are fine-line engineered drawings of gear teeth, hubs and spoked wheels in section, hatched and shaded, overlaid with construction lines, angle arcs and lettered dimensions, offering precise mechanical linework and tooth-profile geometry for use as pattern, diagram or technical ornament.
