US Patent No. 1,187,158, granted June 13, 1916 to John J. McGinley of Philadelphia (assignor to Simon Friedberger), for an open-work twisted net fabric knitted on a lace machine. The fabric is intended for laundry bags and dyers' bags, where torn or cut threads must not ravel. It improves on Frank Clewley's earlier patent No. 1,139,344 by adding a binder thread to each chain, and the text describes the loop structure thread by thread. It includes two figures and three claims.
