Pressed Glass, Aqua, Antique 1893 Patent Date
Antique Hemingray No. 9 glass insulator in a classic aqua blue-green hue. This specific model features the May 2, 1893 patent date embossed on the skirt, representing a significant era in American telecommunications history. Used primarily for telephone and telegraph lines, these insulators are highly collectible for their industrial aesthetic and vibrant glass color.
• Embossed "HEMINGRAY" on one side of the skirt and "NO. 9" on the reverse
• Distinctive "PATENT MAY 2 1893" embossed lettering
• Sharp drip points along the bottom edge designed to shed moisture
• Internal screw threads for mounting to wooden crossarm pins
• Approximately 4 inches tall with a 2-inch base diameter
Condition: Glass retains good clarity with some internal bubbles from the manufacturing process. Minor flea bites and small chips are present on several drip points along the bottom rim, common for industrial field-used glass. Notable rust staining is visible within the interior threaded cavity from contact with a metal pin. No structural cracks or significant surface clouding observed.
