A single-page dictionary entry on shearing machines from Knight's American Mechanical Dictionary. It describes machines that clip the nap of woolen cloth after gig-milling, with a note on the riots in England when machinery replaced hand shearing. It covers Curtis and Marble's cloth and mat shearing machines, a carpet shearing machine for brussels, axminster, tapestry and ingrain carpets, and singeing of cotton cloth. Three engraved illustrations (Figs. 4923-4925) show the machines.
