Details for drawing frames
A 1907 spare-parts catalogue for cotton drawing frames, printed in Manchester by the machine builders John Hetherington & Sons for mill engineers and fitters ordering replacements. Each plate arrays dozens of numbered components—toothed gears, rollers, brackets, levers, cranks, cast housings—photographed against pale grounds in loose grids, giving designers isolated mechanical silhouettes, reference numerals, and ready-made grid arrangements of small objects.
