Draw frames and fly frames : being a practical treatise on the above machines
A practical treatise on cotton-spinning preparation machinery by Thomas Thornley, published in Manchester by A. Heywood in 1898 for mill operatives, overlookers and textile students. Line-engraved elevations, sections and schematic plans show gearing trains, spindles, bobbins, roller stands and drafting paths, all keyed with letters — useful for mechanical diagram motifs, fine hatching, and repeated cylinder-and-shaft forms.
