A one-page dictionary entry from Knight's American Mechanical Dictionary describing the sheep-shearing machine. It explains how reciprocating angular cutters work over guards, much like mowing-machine cutters, and describes an example (Fig. 4942) with a flexible shaft, flywheel and crank drive, and a counterbalance arm. It also mentions a two-operator machine and power sources, and concludes with a list of U.S. patents from 1855 to 1874, including horse-clipping machines.
