A two-page dictionary entry from Knight's American Mechanical Dictionary classifying the feed mechanisms of sewing machines, which move cloth past the needle. It describes clamp, baster or pin-plate, pin-wheel, wheel-feed, needle or awl, two-motioned, four-motioned, thread and upper feeds, citing patents from 1842 to 1869 by Greenough, Howe, Singer, Wilson and others. Two pages of line drawings (Figs. 4880 and 4881) illustrate the mechanisms.
