US Patent No. 1,490,915, granted April 22, 1924 to Herbert Cross of Cynwyd and André Koronski of Narberth, Pennsylvania, for a cotton gin. The machine removes fibre from short staple cotton seed without saws, using a friction ginning roll, a knife made of narrow side-by-side blade sections, a zigzag-flanged feed roll, a brush and grids. The patent argues this method avoids cutting or hooking the fibre and removes the fire risk of saw gins. It has three sheets of drawings (top, side and gear views, blade and grid details), a specification describing the parts and operation, and 22 claims.
