Hemingray Glass Company is the best known and was the most prolific glass insulator manufacturer in the world. Hemingray began as a small operation in Cincinnati in The exact year when actual insulator production ended at the Covington site is still undetermined, but it was likely sometime in the period. The Covington factory also re-opened for a short time in the period. The business offices remained at Covington until , at which time all operation was moved to Muncie. The Hemingray factory and business offices were located on Macedonia Avenue, in the southern part of Muncie. Date codes were embossed on most insulators made after , and the majority but certainly not all of post production was made in clear colorless or off-clear glass.
Nothing is known about what type s these might have been. The factory evidently started up again for a short time in the c. Type s manufactured there have never been identified.

Pleasant Glass Works Mt. Pleasant, NY ? The Telegrapher, Although Newburgh Glass Company appears to have made primarily bottles, it has recently been discovered from brief articles in that same trade newspaper that they also manufactured telegraph insulators, including at least some, if not many, of the insulators marketed by L.
Tillotson in the late s. Evidence strongly suggests that threadless insulators were made in the c.
Although the factory was reportedly listed only in the Boston directory, it is believed that actual glass production started inand might have lasted into early before the new directory was printed. New Granite Glass Works Stoddard, NH An early trade card from this glassworks advertised insulators, both telegraph and lightning rod styles.
Opalescent Glass Company Kokomo, IN to date Insulators types unknown at present were reportedly made here from to After the merging, the total number of plants owned by Owens-Illinois numbered more than 20 in several states, with each assigned a plant code number. Glass insulators were made by O-I at Muncie carrying the Hemingray name until More info under Hemingray. They were most likely made during the mid- to late s. For several months inglass insulators were evidently made here, but the exact types are unknown.
Insulators might date from after that merger as well. Johns Glass Company St. Haffner indicates they did. Please see my article here with more detailed information on Star Glass Works. They are made of a very dark olive amber blackglass.
Most aqua insulators made by Hemingray date up to the circa period, as they began switching over to clear glass during the early s. So c. would be the time span I would suggest for your insulator. The Hemingray is a type of "signal" insulator. Glass Insulators were first produced in the 's for use with telegraph lines. As technology developed insulators were needed for telephone lines, electric power lines, and other applications. In the mid 's a few people began collecting these glass and porcelain insulators. Today there are over collectors, and insulator clubs, national shows, and good reference books are available. Hemingray is the best known and was the most prolific glass insulator manufacturer in the world. Markings used by Hemingray include "HEMINGRAY", "saporiviafrancigena.com", "PATENT MAY 2 ", "PATENT DEC 19 ", "KIMBLE", "LOWEX" and others. Glass insulators were made from at least as .
The great majority of examples are found in shades of SCA sun colored amethystranging from a light pink to a medium-dark purple similar to a typical Whitall Tatum No.

Great pics of some more unusual colored porcelain pieces! Check it out! I have an E. Brody Co. How ever the vertical lines go all the way to the top scalloped edge on the outside. This is odd because all the research show the vertical lines only on the base, and none on the bowl?

Skip to content For a general overview about glass electrical insulators, please check out my webpage here. Cristaleria, S.
Monterrey, Mexico Cristales Mexicanos S. All comments are moderated, so will not appear on this site immediately. There are many different shop numbers seen on Brookfield and Hemingray insulators. Hello, I am curious is there any known color reference guide for Brookfield glass insulators? Thank you, George. Are you asking if there is a book or website available with color photographs illustrating the various shades of color that can potentially be found in Brookfield insulators?
In that area of the site, many people have posted tons of photos of insulators for many years, including lots of insulators that were posted for sale, or just for informational purposes, and usually a color term is included in the description given by the poster of the photo. Also, the hardcopy price guide used by most insulator collectors formerly compiled and published by John and Carol McDougald, now by Don Briel includes listings for more than 14, different insulators including many hundreds, if not thousands, of Brookfield insulators.
I should mention that it is VERY common for insulator collectors to discuss color variants endlessly, and frequently disagree with others on exactly what shade a particular color term actually represents. Sometimes a particular color is given more than one name by different collectors. And besides that, colors may actually appear slightly different to different people. Some who are colorblind may see a color differently than someone who is not. Colors as seen in photos online and in books or magazine photos may not appear exactly as they do in real life.
It would be an interesting experiment. A typical example is the Hemingray NO. Hope this information helps a little! Take care, David. David, Thanks so much for helping me.
I found a color guide for Hemingray insulators on Hemingray. Signal CD insulators and especially the C when it comes to the color green it could be in a dozen different shades of green etc.

Hi George, The Hemingray. In my opinion there are actually as many different shades of green known in Hemingray insulators taking all known Hemingray insulators as a whole, across their entire time frame of the s toor even more, as there are in Brookfields, but some of those shades are much harder to find in Hemingrays. No, the Hemingray company itself never published such a guide.
Besides, it has been over 50 years since the last insulator was produced at the Hemingray factory in Muncie During the time when most Hemingray insulators were being made, color was of very minor importance, except in the case of some insulators such as certain CD signal styles made purposely in blues or ambers, and a few other styles. In fact, on some styles of insulators the backward numbers are almost as common, if not equally common, as their regular counterparts.
Evidently, whether or not the numbers appear correctly or backwards was not considered of any great importance at the factory. Hope this helps! Either your insulator is stained a blue color stain or coating of some sort has been applied to the surface of the glassor it has been irradiated to a shade of cornflower blue, OR you are misidentifying the real color or using the wrong color term of the insulator.
Most Brookfields are found in some shade of aqua blue-green or shades of green. A few are known in light shades of amethyst. Best regards, David.
Hey, I recently found a Brookfield insulator and have a question on the markings. One side reads W. After my research it seemed odd that there were 3 patent dates, but what really interested me was the CAUVET name included in the markings. Seems uncommon, any feedback will be appreciated. You can use those keywords and search Google Images for pics of similar insulators to identify which style you have. Many of them bear those three patent date markings. The date refers to the celebrated Cauvet patent, which basically introduced the idea of screw threading in pintype insulators.
Starting around insulators were made with a threaded pinhole although in reality this was gradually phased in over a period of several years, even some threadless being made as late as the early s. I think the Cauvet patent was still being embossed on SOME Brookfield insulators even several years after the patent had expired. You might try searching through some of these photos posted on the insulators. Thank you for the feedback, the shape is very similar to the CD It has the Brookfield and New York embossing on the skirt, but also some very faint lettering just above the standard lettering.
All of which suggests a mold that was reworked. Thanks, David! I would never have deduced that on my own. The following link goes to a webpage all about the CD style insulator the spiral beehive, most of which have the OCT 14, patent date on them. I know that Oakman also manufactured them but they have the Oakman embossing. Recently found 3 insulators with: W. Brookfield, 45 Cliff St. It is a very snowflaky s of tiny bubbles and in a light aqua.
I have checked on line and in an insulator book but do not find this one anywhere. The dome design is unusual because it flairs out at the bottom. Have you ever seen this one or know anything about it? I know the online sources show these as being 4 inches tall, but there is some variation in the height of tis CD as well as variation in general shape. BTW - the snow is from flakes of furnace brick falling off into the glass batch. It was a sign the brick was worn out and due to be replaced.
The green one pictured would have the 45 Cliff St embossing on its crown.

Some say they were the same shop, others distinguish them separately. From what I can gleen, Huwer likely was in business with Dannenhoffer and probably knew and worked with Dorflinger.
They were located very near each other. Hi Casey, This is a great example of how much confusion and misinformation we can encounter when trying to research a historical subject any subject!
I will pass along what little I have been able to glean. I believe they WERE located next to each other for some period of time, and it is very possible that there was some type of leasing agreement between the two operations. I have found several brief snippets of text from several sites online; perhaps you have already seen them. A billhead with a pic online exists which shows they were at the corner of Maujer and Morgan in He received his educational training in the Volks schule of his native town and soon after being confirmed he became engaged in assisting his father on his farm until he reached his seventeenth year, at which time he decided to learn the trade of glass making.
About this time in company with his brother John he decided to emigrate for the United States and upon settling his family affairs and interests he went to the city of Paris France and from there he corresponded with his brother John and when he learned that his brother was also about to sail for the United States they both secured passage on the sailing vessel Helvetia, and after a voyage of sixty days they arrived at Castle Garden.
Upon his arrival here he went with his brother on the Hudson boat to Albany where he found employment on the same farm where his brother was employed.
Whitall Tatum Company, Millville, New Jersey
He also went back to Albany with his brother and from there to Mentes Station where he worked for some time on the road. He then became a partner with his brother John and they first established a glass manufacturing plant at Maujer street under the firm name of Long Island Flint Works. In Nicholas Dannenhoffer erected a new establishment at Throop and Gerry streets where he remained for five years He started a new building at McKibbin street under the firm name of Williamsburg Flint Glass Works which firm he turned over to a stock company when his oldest son Aloysius died.
He retired on account of illness in but is still at the present time a shareholder of this concern.
CD telephone insulator, marked BROOKFIELD (this is the same style/shape as the "HEMINGRAY" made by Hemingray Glass Company) Brookfield made insulators for various utility companies, (telephone companies, railroads, electric power companies) and some of these are found with embossed initials / names on them, such as A. T. & T. Co., G.E. Co., C. D. & P. Tel. Co., etc. In some cases, such as on glass insulators made by Hemingray Glass Company (in the c period) dots after a date code can and do usually indicate years, but in this case those dots represent the quarter of the year in which the insulator was manufactured. Dating Hemingray Insulators Decoding the date codes. Writen by Bill Meier. All Hemingray insulators since have had mold and date codes on them. In the Price Guide, these are generally referred to as [Numbers and dots] and [Number]. There are several different .
There is an old inn off of rout one,across the road from the inn i have found at least fifteen insulators. I also found a brookfield insulator that is light aqua blue and it is very large for a one piece brookfield insulator.
Albert, Depending on the location of a dump and the surrounding conditions such as next to a stream, creek or river sometimes items can be very close to, or at the surface because of erosion. From you description, it sounds like most of them are telephone-style insulators. Many lines end up with a mixture of different sizes, styles and markings, because when upgrades and repairs were made over a period of several decades, you can end up with a mix of different insulators.
When a line is demolished, or all the insulators replaced and sent to a dump, a lot of different ones might be found in the same area.
Where can i find more photos of things made during that time. Hi Cindy, The products most known to collectors that were made at the Brookfield Glass Company Bushwick Glass Works factory located in Brooklyn are primarily insulators, although bottles and jars were also made.
You could utilize web search engines and search for pictures of those bottles. I hope this will help. Do you know how I can find these? Is it possible the business used some other name other than Trupiano?
