Hemingray https://umek.pro/ , no one is optimistic of the which means of the big “1” that is located on the dome of some Hemingray-42s. They are substantially scarcer than ones without the need of the number on leading. I am guessing it was just a mold number, but I actually don’t know. I have a old insulator from Hemingway with C.S.C. This is clear, seeking for information and mfg date. But there are also really a couple of that are much scarcer and have values that variety into the hundreds or from time to time even thousands of dollars. Your query is really complicated to answer in a brief way due to the fact the field of collecting glass and porcelain insulators is incredibly wide. Paul, either you have a typographical error there, or have misunderstood some thing. The earliest insulators produced by Hemingray have not been particularly identified but would almost certainly be circa 1850s threadless or possibly “Wade” forms made for early telegraph lines. https://umek.pro/company/production , and numerous sizes of spool insulators have been also created. All Hemingray insulators due to the fact 1933 have had mold and date codes on them. Locate A Lot More On Noname Antiques That’s why the Hemingray 42 at some point became the most important insulator and was the final generation of insulators. Somehow they believed this was improved insulation mainly because the wire contacted the glass less, which was ridiculous. There have been lots of designs like that, that made no sense at all. That’s what tends to make collecting insulators so interesting… all those rare experiments are out there. “M in a circle” mark utilized by Maryland Glass Corporation.It was made, mostly for rural use, to insulate the electrical wires they carry so that the electricity does not leak into the pole and into the earth.The Hemingray-42 comes in two designs- the normal and a rarer variation.Incorporated 1870 in Covington, Kentucky business developed glass bottles, jars, oil lamps, light globes, tableware and insulators.I feel it is cheaper to manufacturer and mechanically they are a tiny stronger. On these specific insulators the mold quantity (or mold quantity/letter) is indeed 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 probably comprehend , the “42” is a model quantity and provides no info at all regarding date of production. Bob, no 1 is one hundred% certain what the dome quantity ‘1″ signifies which is noticed on THE Major of some of the HEMINGRAY-42s. Cd 130 1 Cal Elec Works Insulator Glass insulators are an critical aspect of American history. The nice issue about insulator collecting is that there is a big range of good insulators that can be had incredibly for extremely small expense. These had been developed for a steel pin so have a smaller pinhole. Vintage Hemingray Petticoat Amber Otherwise, they didn’t try to make insulators in colors mainly because it didn’t matter. No, the “9” is a model quantity assigned to that unique kind of insulator created by Hemingray Glass Company and does not indicate the year it was created. The quantity 9’s are “pony insulators”, smaller sized sorts applied primarily on nearby, brief distance, low voltage telephone lines. On older insulators, the wording is usually “HEMINGRAY / NO. 9”, on much more current examples the phrasing is typically “HEMINGRAY-9”. The numbers on the other side of the insulator (such as 31-52, as in your case) is a mixture mold and date code. Generally, the “31” is a mold quantity, identifying the precise mold the insulator was produced in, and the “52” is a date code indicating what year the MOLD ITSELF was produced . Absolutely nothing seriously uncommon while I have some that are almost certainly worth $100-$150 – perhaps more. I got interested in insulators when I lived in El Cajon and my neighbor worked for San Diego Gas and Electric. His son had a bunch of insulators on the window sill in his bedroom. You often assume of glass as being fragile, but it was used for some quite industrial uses. 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 used.
