Insulator Historical Timeline!

By Maribeth Keane — August 19th, In this interview Ian Macky describes the origins, types, shapes and colors of collectible antique glass insulators. His son had a bunch of insulators on the window sill in his bedroom. You always think of glass as being fragile, but it was used for some pretty industrial uses. So I asked him about them and it turns out all the original insulator collectors were linesmen. So my neighbor knew a lot of other insulator collectors and it just went from there. There was a national insulator show in San Diego and even one in my hometown. It seemed like there were shows everywhere and collecting insulators was a common thing.

Reprinted from “Crown Jewels of the Wire” , October , page Lee and I share an affinity for the CREB CD beehives due to their aesthetic shape and numerous embossing and shop number variations.

By Ryan Pelham and Beaumont Enterprise. Elton Gish first glimpsed a glass electrical insulator in while admiring a neighbor’s collection. The Lumberton man was enamored by the colorful, translucent glass. So he got one of his own —which was made by the Brookfield Glass Company — and that ignited for collecting a variety of antique glass and porcelain insulators. Gish, who retired in after 46 years as a chemical engineer for Texaco and later Motiva, said he became immersed in the history of insulators while studying old electrical trade journals as a student at Lamar University.

He now keeps vintage company catalogs to assist with his research. He’s also written two books on insulators. Insulators were integral to the growth of America as telegraph lines enabled people to communicate across large distances, he said. Insulators later helped transfer electricity as Americans ventured west, Gish said. Porcelain designs followed glass, when companies realized they were less fragile and could handle higher voltages of electricity.

Insulators are still used on power lines, Gish said, but the factories have mostly moved overseas.

Whether this happened immediately is questionable, but is the general date for when the BFNY began to appear and the WBFNY emb’g may have carried on until service was required or the molds wore out. This information has been proven incorrect by period documents stating work began on the new plant in and was in production before there. Also, it once was believed this move also meant that the Bushwick plant closed in It actually remained in service into As we know it now, insulator production began at OB in It was the first production to be done at OB, and of note, insulator production continued at Bushwick for several years before all insulator production was moved over to OB.

Do we have definite dates for start at OB and stoppage at Bushwick? Which leads to the last comment about embossing types.
