Brookfield Beehive Glass Insulator

The precise time when the Brooklyn plant was closed is nonetheless open to question, but it may perhaps have been around 1912, meaning that each plants likely operated simultaneously for a period of about six years. I am at present functioning on an estate with a substantial collection of vintage insulators. These colorful glass pieces were applied on telegraph and phone poles screwed to wood pegs in the cross arms of the poles exactly where the lines had been tied from pole to pole. No, high voltage insulator under no circumstances published such a guide. Apart from, it has been more than 50 years given that the final insulator was developed at the Hemingray factory in Muncie .
I not too long ago located a Brookfield CD 152 insulator on a pole in Ohio with an embossing error, and I’m questioning if everyone can tell me if it is rare or precious or not since I can not discover any information on the online. I have a W Brookfield beehive insulator with two embossed “nipples / dots” on major and it also has “New York” on it . Dark olive ambers, and dark amber striped insulators.

Cd 134 Brookfield No 41

If you want to press, better get a metal lathe operating. Diamond-I mark on bottom of amber bottle created by Illinois Glass Corporation. The base is marked with the “H over smaller a” logo. There is an old inn off of rout 1,across the road from the inn i have found at least fifteen insulators. All of which,apart for 1, are either brookfield,brookfield new york,or am.tel&tel.co. All of the insulators are from around the turn pf the century 1890,-1920s why would they all be in such close proximity to each other,and why are all of them on the surface of the ground.
Soon after my research it seemed odd that there have been 3 patent dates, but what definitely interested me was the CAUVET name integrated in the markings. Appears uncommon, any feedback will be appreciated. Also, the hardcopy cost guide utilised by most insulator collectors involves listings for more than 14,000 different insulators which includes numerous hundreds, if not thousands, of Brookfield insulators. Generally a quantity, sometimes a letter or number/letter combination. Shop numbers identified a particular “shop” at the factory. Generally a lot of shops had been creating insulators simultaneously.

• This was a flawed notion in these moulds from the begin.


• Prior to 1865, glass insulators’ pinholes have been smooth and the insulators had been just placed over the peg, perhaps with some form of adhesive.


• Of course, with the harm the value of your instance would be somewhat less.


• Insulators have a distinct purple color from years of exposure to the sun.


• This a single started life as a threadless with the massive pin of the 743.two which was 7/8ths of an inch prime and the bottom is 1 & 1/8th inches.

The unusual colors like amber, olive green, cobalt, blue green are a lot more collectible, and the most uncommon are mixed colors or Vaseline glass insulators. Milk bottles with specialized embossing of the dairy cost a lot more to make. Numerous milk bottles of that time period had been produced with “painted labels” or “ACL” graphics. The first ACL bottles date from the mid-1930s so if there were any bottles created for Trupiano they may possibly have been an ACL sort.

Potential Really Uncommon Sought Just After Insulator!

It can be found as late as the Round Base Canadian Pacific Ry. These two moulds are straightforward to tell from every other. I evaluate the domes to the ends of an egg, one particular with a pointy dome and the other as a rounded dome. They utilised the 743.two pin , it was altered twice as noted beneath.

Cd 147 Patent Oct 8th 1907

This was the last style of Hemingray mold developed. Note the more narrow best that flares out to the bottom. If one particular has a ram press, these could conceivably be created that way. That method uses comparatively dry clay and presses it below good hydraulic force into the final shape in the mold.
In the fall of 1874 Burlington Glass Co. started producing glass. I believe that the CD 743.two was utilized there till about 1875 as a threadless. It's pin is employed in the CD 743.1 insulators at that time. The first mould for this style of a threadless insulator was the CD 743.two aka Cannon Ball. The pic beneath is my favored , it is a lilac lavender with a slight purple tint. Brookfield Glass Firm began in 1864 as Bushwick Glass Works, a bottle manufacturing firm.
When my boys have been young, I got them interested in collecting insulators so I could appear by means of the antique stores and malls without the need of them becoming bored or running around. From you description, it sounds like most of them are telephone-style insulators. A lot of lines finish up with a mixture of distinct sizes, styles and markings, for the reason that when upgrades and repairs have been created more than a period of quite a few decades, you can finish up with a mix of distinctive insulators. When a line is demolished, or all the insulators replaced and sent to a dump, a lot of distinctive ones may possibly be discovered in the exact same region. Thank you for the feedback, the shape is pretty equivalent to the CD 126.three and is light aqua colored. I discovered a piece of history on Brookfield glass and was capable to narrow down the date using the street address, just couldn’t find info on CAUVET embossing, only that the patent was purchased by Brookfield.
