This month we cross the Atlantic to England where insulators were being advertised during the 1880's.

Joseph Slater Lewis' self-binding insulator was being advertised in the Electrical Review of London in the December 2, 1882 issue. This was really an all purpose insulator design: "No tools required either to attach or detach; can be applied in any position no matter how close to walls, bridges or other obstacles,' will bind No.4 wire as easily and firmly as a No. 13; every portion open to cleansing action of rains -- less risk of porcelain becoming covered with coating of rust; can be used as a terminal insulator, the loop from which can be instantly detached; inexpensive."

Lewis was granted a U.S. patent May 1, 1883. A similar patent with improvements was granted to Frank L. Pope six months later (December 25, 1883) and led to the manufacture to the CD 110.5 and 110.6 glass styles by the Iron Glass Company of Haverhill, Massachusetts under contract to the National Insulator Company.
