A one-page dictionary entry from Knight's American Mechanical Dictionary describing the silk-reel, an apparatus for unwinding silk filament from cocoons. It explains how cocoons are softened in heated water, how several filaments are joined and wound onto the reel, and how a traversing guide distributes the thread. An engraved illustration (Fig. 5087) shows the apparatus, and a closing note mentions the automatic silk-reel used to wind thread from throwing-mill blocks into hanks.
