I simply don't have the time, energy or knowledge to answer many of the questions submitted here. That operation was principally a bottle house, and did not produce insulators. He remembers being told to throw them away. You can search google with the keywords: Hemingray T. 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. However, I am not sure exactly when it was discontinued. There are often dots present after the year code.


The electric telegraph in the United States was developed by Samuel Morse in , and the first message was sent by Morse in The telephone was invented by Alexander Graham Bell in Insulators were necessary by serving as a medium for attaching the wires to the poles, but much more importantly, they were required to help prevent electric current loss during transmission. Both glass and porcelain insulators have been used since the early days of the telegraph, but glass insulators were generally less expensive than porcelain, and were normally used for lower-voltage applications. The oldest glass insulators date from about Many of the glasshouses that made insulators also produced bottles, fruit jars and other glassware. Clear glass was used with some exceptions primarily after about Hundreds of different styles were developed over the years, and insulators are found with a wide variety of embossed names, initials, patent dates, and other markings. This system was created and used by N. The CD Consolidated Design numbers basically identify insulators by their shape and profile, regardless of exact embossed markings, glass color, or base type. But all of them would be known as CD s. Hemingray is a CD Hemingray is also a CD There are several insulator websites that discuss this classification system in more detail. CD numbers are used on many ebay auctions, although non-collectors who list insulators on ebay or other internet sales sites may not be familiar with the system.

The first glass factory in Millville was built in on the banks of the Maurice River by James Lee along with several other men. Whitall entered the business in partnership with G. Haverstick and William Scattergood.

Whitall Tatum produced very large quantities of bottles and fruit jars throughout much of read more mid- and late 19th century.

Pharmacy, druggist, barber, perfume, chemical and other types of bottles in various colors and styles were produced, and some of them are now avidly sought by antique bottle collectors. Less commonly-seen are examples found in a beautiful rich teal green glass, as well as cobalt blue.

Note : some of these earlier clear glass bottles may turn a pale amethyst color if subjected to long exposure to sunlight. See this page on Artificially Purpled Glass. However, W-T made up for lost time by producing millions of insulators during the ensuing years.

No doubt they supplied insulators to many firms check this out in the Eastern states, but over the entire country as well that had previously purchased from Brookfield. In the s and on into the s and s Whitall Tatum continued to produce large quantities of bottles of many types, sizes, and colors. That trademark is generally believed to date beginning aboutand appears on machine-made containers, not mouth-blown bottles.

Whitall Tatum was purchased by Armstrong Cork Company in It is likely there was a gradual changeover on bottle and jar molds starting aroundbut that transition probably occurred over several years time. Realizing that a large number of molds were in use, I would suspect it took a while for all of them to be re-tooled.

I do NOT know if the bottles followed that same timeline!! I have never seen any bottles with the WT mark that appear to date after the s, or maybe the early s at the latest. He was referring to a chart copied in an archaeology report by Dale Berge in That chart was published by Owens-Illinois in I noticed on that same chart there is also another instance of a mark that was presumably no longer in use by …….

I think Owens-Illinois was either somewhat slack about making sure their chart was up-to-date, or they merely wanted to include certain well-known marks that might still be encountered on relatively-recent glass containers made within the last decade or two of the publication of dating glass insulators chart.

With the rapidly decreasing demand for glass insulators, production at the Kerr plant continued to diminish as the s wore on. Soon afterward, the insulator molds and equipment were moved to the Kerr Glass plant located in Dunkirk, Indiana. Ball-Foster took control of the factory inand in chart dating site, after years of nearly continuous glass production, the factory was shut down permanently.

If anyone has more recent information on this property, please contact me! Thank you! Note: for a webpage on this site with an extensive list of glass insulator manufacturers, please click here. Click here for the Glass Bottle Marks pages, page one.

Please click here to go to my Home Page. For some more info on the Kerr Glass Manufacturing Corporation, see that article here. Made in U. WT triangle Logo. From what I have looked up it shows to be to Is there something that would narrow the date to a closer year of manufacture? Dane, on the first two insulators you describe, the numbers are mold numbers, not date codes 34 and You are correct on the date codes of and Sorry about that. If a reader has better info, please write!

Any ideas as to where this was from? The top of the bottle is tooled. I have a small glass jar, painted black on the bottom, steel lid. Mark on jar is: W. USA and what looks like B Any idea what it was used for? Thank you for providing your knowledge and sharing your experiences. You mentioned that most question have already been asked and answered.

Please forgive me, can you share why and how you got involved? Https://ubeat.xyz/lifestyle/biggest-australian-dating-sites.php I assume the higher the number on the insulator the less value? My dad is a retired telephone company worker. For me the insulator symbolizes hard work and sacrifice. It has allowed me to attend college. My dad worked many hours climbing the poles. He remembers being told to throw them away.

They all seem beautiful and valuable. Any wisdom you would like to share would be great! Hi Tammie, Thanks for your post. It is such a wide source of collecting and study. There were dozens of different insulator-manufacturing companies. Some of them used style numbers such as 42 on most of their insulators such as Hemingray, Whitall Tatum, McLaughlin, and Pyrex but others did not.

In a very general sense, some of the insulators made by Hemingray with lower style numbers such as their NO. There are lots and lots of exceptions. Some of their newer, larger power styles with larger style numbers such as 71 can be somewhat harder to find.

Honestly, there are no easy answers to this question. My advice to you would be to check out the insulators. There are several insulator collecting and discussion forums now on Facebook. In general, most of the glass insulators you see at a yard sale, flea market, or an antique store will be of the more dating glass insulators variety.

Some of the most common insulators which were installed in untold millions around the United States would include: The Hemingray, Hemingray, Hemingray-9, Hemingray, Hemingray, Hemingray and Hemingray And there are others. Keep in mind that an insulator in a more uncommon color will usually have more value than a similar example of the same style in a typical aqua or clear color.

Most insulators made by Whitall Tatum or Armstrong are common, but again, some exceptions are out there. Most casual sellers on ebay do not know the average value of an insulator they are listing, and often try to start an auction at an outrageously high starting bid………and then they get zero interest in their auctions.

Check out the hemingray. Hope this helps a bit, David. It usually appears to the upper left of the actual embossing. Hope this helps, David. It was found near Jim Thorpe, PA. Any way you could shed some light on what I have? Most agree, european jewish dating site think the W-T CD s are in bluish aqua, greenish aqua, straw, peach, purple, or light pinkish color. MOST of the later ones, the CD style, appear in a clear or off-clear colored glass, some with a dull grayish tint to the glass.

I found a square brown bottle about a foot tall rectangular dating glass insulators shape with WT in a triangle on the bottom w an A and B on either side any answers on this? Hi Adam, Whitall Tatum made thousands of different styles of bottles over the years, so their mark will be found on a wide variety of containers.

Sounds like it might be one of many types of amber bottles used for chemicals, cleaning products, etc. Hi Denise, I am publishing your post. Maybe someone who lands on this website will have more info for you. However, I am very skeptical it would be easy to find any such pictures or lists, if they exist. If you can find any city directories of the https://ubeat.xyz/social/do-batman-and-wonder-woman-ever-hook-up.php or s, you might find information in those directories on people who worked at Whitall Tatum.

Dating glass insulators geneaology- oriented websites may have city directories in their databases with information that could dating site in usa handicap helpful. No guarantees, though!

Take care, David. Hello, hoping you can help me identify a whitall tatum insulator i have. Back skirt is No. Its a light aqua insulator as well.

From my minimal research it appears to be an early embossing style that very few were made. Thanks for any info. Bill, It is a very common insulator, made in the period. Thanks David. Is is possible to post pictures on dating glass insulators site.

That would be much better than my vague descriptions. You are welcome to email me pics.
