U | 1,015,229 | January 16, 1912 | Insulator Suspension using multiple parts cemented together on tubular core. The patent is similar to the commonly referred ""Micarta Core"" insulators, but experts believe the patent was not used for those insulators. The glass insulators may have been made by Hemingray. |

1912 | ||||||
U | 1,015,224 | January 16, 1912 | Insulator Suspension insulator of insulating rope, hoods, and arcing rods. [This looks very close to the handful of glass suspension insulators found in 2002 in northern CA by Paul Greaves and Mike Spadafora. The glass was most probably made by Hemingray. No markings were found.] |
