On 1 of their older insulator types, the CD 126 “blobtop” , I have personally observed the shop quantity “4” oriented generally, backwards, upside down, and sideways, on many mold varieties!! Evidently, no matter whether or not the numbers appear appropriately or backwards was not considered of any terrific significance at the factory……. Just as long as the numbers could be quickly seen and recognized by the workers on the “cold end” of the lehr. Of course, the reason why the number appears backward on the insulator is due to the fact it was engraved “correctly” on the inside of the insulator mold. To seem “normal” on the finished insulator, the quantity had to be engraved backwards in the mold. In the 1870s and 1880s, the will need for insulators improved as far more telegraph lines were place into use.

• Initial of all, are you absolutely positive that they utilized bottles that have been essentially marked with the name “Trupiano”?
• Does everyone have any info about a cobalt blue Brookfield New York insulator.
• In addition to, it has been more than 50 years due to the fact the last insulator was made at the Hemingray factory in Muncie .
• And besides that, colors might actually seem slightly diverse to distinctive persons.

CD 133 style glass insulator marked “BROOKFIELD” and “No 20”. The 1890s saw increasing production of insulators for electrical power lines. Brookfield was incredibly fond of covering their insulators with lots of embossed markings, such as several patent dates, in the 1870s, ’80s and 1890s. suspension insulators Suppliers and Quite a few of them bear those 3 patent date markings. It may possibly be viewed as as a form of marketing and advertising hype or “brand name bragging rights”. The 1865 date refers to the celebrated Cauvet patent, which basically introduced the concept of screw threading in pintype insulators.

History

I didn't recognize it but apparently "beehive" is utilised by folks to describe the old style telegraph/phone pole insulators. "Standoff" appears to be much more frequently utilized for these. An 1880's era CD 145 CREB telegraph insulator that is actually packed with tens of thousands of micro bubbles. This is a pretty scarce function to locate these really old beehives with as the early Brookfield firm seemed to be a great deal extra cautious about glass quality than it was in it's later years. Mold quantity “33” on the base of an emerald green soda bottle made by Owens-Illinois, Inc. Millions of these kinds of “generic” non-returnable soda bottles have been made for many years.



In 1921, production had stopped at the Old Bridge plant and the enterprise dissolved. This Hemingray embossed version is embossed with "Double Petticoat" on the rear skirt. Note the wire groove is lower down and the insulator is slightly shorter than the other molds. This mold style only seems in and embossings. From time to time when we are riding out in the country, I catch a glimpse of an aqua blue insulator on an old phone pole and it tends to make me smile.

Short History Of Glass Insulators

I would suggest you take some of your insulators to an insulator and/or antique bottle show and ask a quantity of dealers and collectors there to “name the color”….. power line insulators Just to see what kind of answers you will get!! Your insulator is not frequent, but not that rare either. It is listed as index beneath the CD 152 “BROOKFIELD” listings in the price tag guide.

Cd 138 W Brookfield

I do not have the very most recent edition, but the value as shown in my book reads “10 to 15” dollars in aqua. Of course, with the damage the value of your instance would be somewhat significantly less. Any color other than aqua, such as true green or olive amber, will be worth far more. BTW, there is also a SB version with that embossing error!
