710 Hemingray Insulators Suggestions
They created massive insulators for higher voltage electrical lines. Hence, the CD-128 form was the only tiny size ever made. When I was at Chico State, we utilised to go up the Feather River Canyon and obtain them along the railroad, and also discovered. We also found some Mickey Mouse style running to an old sawmill, and some pony style insulators, likely from an old telegraph line.

He got a truckload of green gin bottles and melted them down and produced a batch of insulators. No matter whether you are a collector or searching for facts on glass insulators, we are positive that with the data dished, you now know how worthwhile glass insulators can be. If you like glass, there are some incredibly stunning colors of insulators, and individuals want those rare pieces of glass. If only I had funds then, I was just a kid and 5 bucks was a lot of funds and ten was way more than my price tag range. Diamond-I mark on bottom of amber bottle produced by Illinois Glass Corporation. In addition to the Hemingray versions, the CD 128 was also made in Massive quantities by Corning Glass Works, and their version is marked with the PYREX brand name.

The wealthy dark blue colour adds to the beauty of this insulator, and this rare item retails for a whopping $5000, miles ahead of its peers. Its uncommon shape, rarity and wealthy history make this antique piece best the list of the most valuable insulators in the planet. Amber and fancy blue colors had been only created that color on purpose by Hemingray, so they could be applied to mark certain lines , so they have been under no circumstances common. By “blue”, persons typically imply “blue finish of the aqua spectrum”, which is a distinctive beast from correct blue .

I have a old insulator from Hemingway with C.S.C. This is clear, looking for info and mfg date. Looking along the major of the Hemingray workplace developing on Macedonia Ave. Photo taken September four, 2011 at Muncie, Indiana. Hemingray started as a tiny operation in Cincinnati in 1848. We can assistance narrow it down by answering just a handful of fast inquiries below.

How Significantly Is A Hemingray Glass Insulator Worth?

Shortly soon after, he had them on his sales table at insulator shows for $300. For comparison, a cobalt EC&M sells for $three,000+ despite there being anything like 900 of them recognized, due to the good desirability. Somehow they believed this was superior insulation since the wire contacted the glass significantly less, which was ridiculous. There were many styles like that, that created no sense at all. That is what makes collecting insulators so interesting… all those uncommon experiments are out there. glass insulators for power lines is a a single or two digit quantity, at times followed by a letter.

“Scales” emblem used on containers made for McKesson & Robbins. This is on the base of a little green glass jar, perhaps for an ointment. The base is marked with the “H more than smaller a” logo. Bob, no one is one hundred% sure what the dome quantity ‘1″ signifies which is observed on THE Major of some of the HEMINGRAY-42s. It could have been meant to signify a specific set of molds made use of on a distinct automatic insulator-pressing machine. Again, the purpose (in the case of THESE Particular INSULATORS!!!) is not specific at this time.



Andrew, I recognize those “Mason’s Patent Nov 30th 1858” forms jars with the HGCO monogram on the reverse are indeed products of the Hemingray Glass Organization. I cannot date them exactly but I assume they are from the 1870s-1880s period. There are quite a few slightly different monogram styles, and they are listed in the official fruit jar “Redbook” as #1851, #1853, and #1854. I cannot say how uncommon they are, but they are undoubtedly not a popular jar. Hemingray was the globe biggest manufacture of glass insulators. The earliest Hemingray insulators are most likely lightning rod insulators from the late 1850's.

Connect To History

But they are so well-known they are all snapped up immediately, everyone wants them. So I asked him about them and it turns out all the original insulator collectors were linesmen. They’d go out and do a job and there’d be an old pole with antique insulators on them. They’d swap out the old ones with the new ones and to everybody else, the old have been just junk. So my neighbor knew a lot of other insulator collectors and it just went from there. There was a national insulator show in San Diego and even 1 in my hometown.

This section is for cataloging projects of embossings and oddities in Hemingray insulators that are beyond the scope of the general insulator guide. If in doubt or suspicious, you can always use the Hemingray Infoto check rare criteria. Glass insulators are an critical component of American history.

What Is The Rare Glass Insulator?

In the case of the instance in front of me, the “8” is followed by 7 dots, BUT the only difference getting a different mold quantity/letter combo. The 10B is a mold number, serving to recognize the precise iron mold utilized. On these distinct insulators the mold number (or mold number/letter) is certainly on the REVERSE side, positioned underneath the “MADE IN U.S.A.” embossing. Regrettably, there is no way to date the aqua-colored Hemi-42s. As you possibly realize , the “42” is a model quantity and gives no info at all concerning date of production. The “brass bushing” or “thimble” insert was put in location by machine, at the time the insulator was created and the glass was nonetheless incredibly hot.

These insulators are extremely sought following by collectors and every person. I also have an insulator on my web-site that is clear and has a streak of Cobalt blue through it. The guys who produced it got permission to run a batch of Cobalt blue insulators, mostly for collectors.

So let’s explore how to discover out if your glass piece is a diamond in the rough. The Hemingray 42, a telegraph pin insulator developed by the Hemingray Glass Enterprise, is extensively found in North America. Ralph Hemingray was holder of many insulator associated patents such as a patent for a glass batch mixer and several patents for glass presses. He was the very first born son of Robert Hemingray and had two brothers, all of which had been active in the glass business.
