US patent No. 99,503, granted February 1, 1870, to Charles Wall of New York and John Stewart of Brooklyn for an improved drawing-frame for dressing flax, hemp and manilla fibre. The invention adds a series of revolving comb-cylinders working over an endless carrying-apron to the existing endless chain and condensing apparatus, so combing and drawing into slivers happen in one machine and the separate lap-machines are no longer needed. The document has a sheet of patent drawings (side elevation, plan and transverse section) and the printed specification with a single claim.
