Detrick arches showing their adaptability to all types of boilers and stokers, special furnaces and oil stills
A 1921 trade catalogue issued by the M.H. Detrick Company to sell its suspended refractory arches to boiler-plant engineers, furnace builders, and industrial architects. Most plates are sectional line drawings of boilers, stokers, and oil stills printed in black on cream stock, with hatched firebrick, tie rods, and hanger castings drawn to scale, alongside grey halftones of furnace interiors; useful for hatching patterns, industrial cutaway diagrams, and mechanical linework.
