US Patent No. 1,772,080, granted August 5, 1930 to Arthur J. Harris of Paterson, New Jersey, for an improvement to narrow-ware looms. The invention concerns coaxial, separably coupled warp supply and fabric receiving spools. The receiving spool is flanged so that a space is left between each end of the wound fabric layers and the flanges. If an end convolution slips off, it stays under traction control and the band does not wrap the spindle and snap. The scan has a sheet of patent drawings (a side elevation of the loom and a detail of the spools) and the specification with a single claim.
