The windmill as a prime mover
A technical treatise on windmill design and power output by engineer Alfred R. Wolff, published in New York by John Wiley & Sons in 1885 for engineers, millwrights and mechanically minded readers. Wood-engraved plates show sail wheels with radiating slatted vanes, governor and vane-turning linkages, pump rods and gear housings, many lettered or numbered as keyed diagrams, offering designers spoked circular forms, lettered mechanical schematics and fine-line hatching on toned paper.
