Discussing star-embossed glass insulators is similar to discussing the Loch Ness monster. The Acme Glass Company made use of a five-pointed star mark. 9311 Extra Deep Groove, double petticoat insulator Cat. 9312 Pony, Deep Groove, double petticoat insulator These items are embossed with a five-pointed star. Woodward relates that General Electric had insulators made for them embossed with a raised, five-pointed star. This facility, known as the "Lower Works", produced glass insulators when fuel was available.
Everyone has a theory or a belief but records are virtually non-existent. There was also a Star Glass Company in New Albany, Indiana (1860 to 1900). Today we refer to these insulators as CD 112, CD161, CD 162 and CD 160 respectively. It seems safe to assume that the five-pointed star embossing was intended as a user mark for General Electric items. came into existence in 1903 and the plant at Old Bridge was already producing insulators for the Thomson-Houston Electric Company (T-H E. The insulators produced were of the CD 102, CD 112, CD 160, and CD 164 variety.
The CD number is from a classification system developed by collectors that refers to the shape of the insulator and is completely independent from the Hemingray Glass Company.
The Consolidated Design number is a unique number the insulator collecting hobby has assigned to every known insulator style. The most recent price guide currently available is the 2015 edition, published by Don Briel.
The CD 281 was a style made only by Hemingray Glass Company and Lynchburg.
If Lynchburg did not make new molds for this style, which seems highly unlikely given its obsolete nature and the short production run of CD 281 (one week), the conclusion is that somehow Lynchburg obtained Hemingray molds for this style. There still exist production and sales records from the Lynchburg plant. From those records, two facts argue against the CD 280 being a Lynchburg product.
Colors: Yellow Green, Green (Aqua is reported but not confirmed) The origin of Lynchburg's CD 281 is not certain.We know that Lynchburg made extensive use of recycled molds, not only from Gayner Glass Works through its connection with William Gayner (see Lynchburg Glass Corporation) but from other companies as well, including Brookfield and NEGM (perhaps through Brookfield).This style of high voltage side tie insulator was already becoming obsolete by the early 1920s replaced by various saddle groove or top groove insulators.Mary and her husband, John, have been collecting and selling various insulators for years.As a young child, John and his father would walk up and down along train tracks, collecting discarded insulators that had been thrown down from the telephone poles.
