Hemingray No. 42 Glass Insulator

This is a vintage glass electrical insulator, specifically a Hemingray No. 42 model, which was a standard for telephone and telegraph lines in North America. The item is crafted from heavy, thick-walled pressed glass in a deep green hue, often referred to in collecting circles as 'Hemingray Blue' or 'Aqua Green' depending on light saturation. It features a tiered, bell-shaped design with a rounded 'dome' top, an middle wire groove for securing lines, and a flared 'petticoat' base. Embossed on the lower skirt is the clearly visible manufacturer's mark 'HEMINGRAY-42', likely accompanied by a 'MADE IN U.S.A.' stamp on the reverse side. The interior is threaded to allow it to be screwed onto wooden crossarm pins. In terms of condition, there is a prominent chip or 'flea bite' on the middle ridge, which is common for these industrial artifacts after years of outdoor service. There is a visible layer of surface grime and soot, particularly in the grooves, which is a natural patina for insulators exposed to coal-fired train smoke or environmental pollution. The base appears to have 'drip points' (small teeth-like projections), which was a design feature intended to help water shed away from the pin. Given the markings, this piece likely dates from the 1920s to the 1950s.
