Ian Macky Explains The Colors And History Of Insulators
A second glass plant was built in Old Bridge, New Jersey, and from recently found evidence by collector/historian Bob Stahr, that plant appears to have commenced glass production in about 1906. The precise time when the Brooklyn plant was closed is still open to question, but it might have been about 1912, which means that both plants likely operated simultaneously for a period of around 6 years. I also have an insulator on my web site that’s clear and has a streak of Cobalt blue by way of it.

His son had a bunch of insulators on the window sill in his bedroom. While on the topic of “ghost embossing” on insulators, I might incorporate a couple of web links right here. The molds had been engraved so the letters have been dug in. It's a wonderful item, and yours has the added bonus of bold embossing, which makes it a lot more appealing given that a lot of crown embossed Brookfields are hard to read. That is why the Hemingray 42 at some point became the primary insulator and was the final generation of insulators.

The Brookfield business created more than one hundred kinds of insulators, all meant to insulate the wires from touching other conductors. https://macdonald-gay.hubstack.net/suspension-insulator-for-sale Most of these were manufactured in their Brooklyn, New York plant. I do not know of a glass insulator with an “1880” patent date, but I think you are hunting at a single marked with 1879 and 1870 patent dates, and that would likely be a CD 126. The CD 126’s had been produced from around 1878 to and several distinct molds have been produced with slight variations in precise lettering. Your insulator is not prevalent, but not that uncommon either. It is listed as index below the CD 152 “BROOKFIELD” listings in the price tag guide.

Although on the subject of “ghost embossing” on insulators, I could possibly involve a few internet hyperlinks right here. The first 1 is a glossary of insulator terms, and a brief mention can be found beneath the “G” listings. I ran across a CD 102 embossed Brookfield and New York on the skirt. Nevertheless, it has a “7” embossed backwards on the leading. If you look from the bottom thru the hole, the “7” appears right.

It seemed like there were shows everywhere and collecting insulators was a popular point. 3.875" tall 1- CD-164 style olove green with BROOKFIELD and No. 38 on bottom skirt, approx. 3.75" tall. Thank you for the feedback, the shape is extremely equivalent to the CD 126.3 and is light aqua colored. I discovered a piece of history on Brookfield glass and was able to narrow down the date utilizing the street address, just couldn’t come across info on CAUVET embossing, only that the patent was bought by Brookfield. Devoid of seeing a picture, I would guess your insulator is one particular of the sorts classed as a CD 133 (“signal”), CD 145 (“beehive style”) or CD 126 (“blob top”). These CD numbers are component of the “Consolidated Design” cataloging technique utilized by insulator collectors.



Many of them bear those 3 patent date markings. It might be viewed as as a kind of advertising hype or “brand name bragging rights”. The 1865 date refers to the celebrated Cauvet patent, which generally introduced the notion of screw threading in pintype insulators.

This results in the faint ‘repeat’ of embossed lettering on the finished insulator. Christian is displaying the colors far more probably to be noticed in Hemingray insulators, but there are other MINOR shades of colour that are hard to define which are not shown. In my opinion there are basically as quite a few distinct shades of green identified in Hemingray insulators , or even far more, as there are in Brookfields, but some of those shades are considerably harder to locate in Hemingrays.

That is a single of the colors Hemingray provided for their insulators, there are thousands of them out there. But they are so well-known they are all snapped up immediately, everybody desires them. “M in a circle” mark applied by Maryland Glass Corporation. Right here, as embossed on the base of a compact cobalt blue Bromo-Seltzer bottle.



Prior to 1865, glass insulators’ pinholes have been smooth and the insulators had been just placed over the peg, possibly with some sort of adhesive. Beginning about 1865 insulators had been created with a threaded pinhole . I assume the Cauvet patent was nevertheless becoming embossed on SOME Brookfield insulators even many years right after the patent had expired. I should mention that it is Very prevalent for insulator collectors to go over colour variants endlessly, and frequently disagree with other individuals on specifically what shade a unique color term truly represents. Sometimes a particular colour is provided much more than one particular name by diverse collectors.

Having said that, if you follow this guide you can get a fantastic concept as to when your insulator was created. It is common to want to know the origins and age of an insulator you located.
