An iron frame used by printers for holding sufficient type for
one side of a sheet. The type is first set up letter by letter in the composing stick, and is then transferred to the galley, where it appears in columns. It is next divided into pages, and then transferred to the chase, where it is held tight by quoins, or small wedges of wood. The word is French, chasse (a frame); our case-ment. (See STICK.)
