US Patent No. 51,744 granted to Herman A. Oesterle of Philadelphia for a machine that makes netted or lace fabrics, such as sashes worn by army officers. The specification describes a frame, shuttles with bobbins, spring catch-levers, a sliding guide bar for warp threads, beaters and a take-up drum, and explains how shuttle threads are looped around pairs of threads to form the net. It ends with five claims. The patent drawing shows side and plan views of the machine and a diagram of the fabric produced.
