Vaughan's carding lessons. "For the mill boy" ..
A short trade manual on cotton carding by M. H. Vaughan, published around 1905 in Huntsville, Alabama, for mill hands learning to set and calculate machine drives. The plates are line diagrams of toothed gears and pulleys labeled with tooth counts and letters, useful as simple mechanical schematics, cogwheel motifs, or diagram-style page ornament.
