US Patent No. 12,050, granted December 12, 1854 to Gaetan Bonelli of Turin, Sardinia, for operating looms by electricity. It replaces the punched cards of the Jacquard machine with electro-magnets that hold up the hooks and healds. The pattern is carried on a varnished metal cylinder or sheet, or set up with type-like pieces in a grate, which opens or breaks the current to each magnet. The text covers magnet and hook arrangements, ratchet and lever mechanisms for advancing the pattern cylinder, comb contacts, and methods for multicolor wefts such as shawls. Four sheets of drawings (Figs. 1-24) precede the specification and claims.
