US Patent No. 1,139,344 granted to Frank Clewley of Philadelphia in 1915 for a twisted-net fabric. It describes an open-work knitted fabric made on a rib-lace machine with two guide bars, in which paired threads interloop in alternating chains so that torn or cut fabric cannot ravel far. The fabric is intended for laundry bags and dyers' bags. Two line drawings show the loop and chain construction.
