US Patent No. 551,510, granted December 17, 1895 to Rowland Creasey Richardson of Philadelphia, for an improved double-lift Jacquard apparatus. One set of cards indicates the hooks for two sets of griffs at once, and the griffs are raised partway to hold the selected hooks in place. A single jacquard can then do the work of two, or run at half the speed, which suits Nottingham lace-curtain and upholstery looms. The patent has five sheets of drawings (Figs. 1-24) and a specification with eight claims. It describes the lace-loom mechanism, including shuttles, guide-bars and pattern threads, and explains stitch formation (net, clothing, shading) in diagrams.
