Hemingray No 9 Patent May Well Two 1893 Glass Telephone Insulator
Some places had extra than one power enterprise on a pole, so various colors have been use to assist the lineman distinguish what line they had been operating on. Also, the poles employed unique forms of circuits so particular colors had been utilised for the distinctive circuits. A great example would be Kansas City, MO utilizing cobalt, peacock, and electric blues on their street lighting circuits.



Cobalt blues were used mostly as line markers in Ellsworth, Kansas and near Oklahoma City, OK. CD 162 signal insulators were created for phone and low voltage power distribution that have been developed from late 1880's to the 1940's. Drip points are a favorite subject among Hemingray collectors. The argument can certainly be created that drip points had been just a gimmick, a way for Hemingray to differentiate his item from his competitors.

CD 302 insulators are a moderate size power insulator that have been developed by the Hemingray Glass Company in Muncie, Indiana. They have been made from c1893 to 1920 for use on early power distribution with a voltage rating of 40,000 volts. CD 302 insulators are known as the "Muncie" style insulator, even though some have the Ohio embossing on the reverse side rather of Muncie Type. There are a lot more selection of colors made in the style of the CD 162 Hemingray insulators than any other CD style or glass enterprise. Hemingray-42 is a single of the most widespread designs of glass insulators.

Two Blue Hemingray Insulators

My collection of insulators have all been located laying around in various components of the state. I just picked them up because I liked them and they make an fascinating display in the yard. They definitely took a battering the mother of all hailstorm we had final evening but they all survived. Just a couple of of the far more colorful pieces I had in the previous.

glass Porcelain insulators of the actual insulators shown above had been produced in the second quarter of the 20th Century. It was a time when makers of glass insulators were having to compete with porcelain insulator manufacturers for marketplace share. Lots of low voltage glass insulators made during this period were formed in dark colored glass to compete with similarly colored porcelain products. The Value Guide lists D-512's in red amber at $50 - $75.

Diamond-I mark on bottom of amber bottle produced by Illinois Glass Enterprise. OVG monogram on the base of a “Daisy & Button” shoe toothpick holder in amber glass. A few of the related error molds are listed in the value guide under a various EIN, such as the “HEMINGAY” mold spelling error, which is listed as EIN . If the value in this column says WANTED, then that particular insulator is on my wanted list! If you have that insulator and would like to sell it, click on the WANTED hyperlink to submit photographs and contact me. The Embossing Index Number is a distinctive number assigned by the collecting hobby to every distinct embossing for an insulator design.

A rural farm outside of Bryan, Ohio with a remnant single-user open wire phone line with two glass insulators. All insulators have the Hemingray / Patent Might 2ND 1893 on the front embossing. Some of these very same molds exist in each smooth-base versions and a version with sharp drip points and the “May two, 1893” embossed lettering. By 1892 Fred started promoting electrical and telegraph supplies, most of which had been made to his specifications, with the Brookfield Glass Organization and also the Hemingray Glass Organization making the glass insulators.

Antique bottle and glass neighborhood where collectors, diggers, traders and anyone with an interest in antique bottles meet.. This is a "baby signal" utilised in phone and low voltage electrical and signal applications. The little letter mold set dates from 1938 and Hemingray applied it until the 1950s, I feel. If you can present the numbers and dots we can date it a lot more precisely.

The "PROVO" name can be found on 4 different CD style insulators as No. , No.1 , No.two , and No. 4 (CD 303.five). Rather than leave all of my Hemingray insulators outside I've brought some of them indoors and added some battery faux tea lights. Not enough light to study by but nice ambiance in the living area in the evenings. There have been a lot of CD 160 Hemingray-14's on quite a few of the poles downtown Hamler only. CD 160's are a smaller sized size of the CD 162 and nickname the "baby signal." They had been a lot rarer to see along railroads. On this pole there have to of been amongst of the CD 160's.

Green Cd 162 Hemingray Glass Insulator

An additional variant has a letter “M” placed to the left of “No 9”, possibly resulting from the mold worker beginning to engrave “MAY” on the second line, and then realizing his error. Two examples, both from the same precise Hemingray No 9 “STAMP” style mold. The 1 on the appropriate is the wider version (produced following the mold was re-tooled). It might have been manufactured months or years soon after the one particular on the left. This pole along with the crossarms likely date back to the 1920's when the states upgraded most of its power distribution in the course of this time.



If you have any to add to the list let me know (Select "New listing for Hemingray dots project" as the make contact with explanation). Really feel totally free to submit 1 currently on the list if it is a unique mold quantity or year. Please consist of the precise embossing with the dot location, EIN, mold info If the dots are in odd places attempt to make notes of their placement or send a photo. L.G.CO.export-style beer bottle, standard mark as seen on Lindell Glass Business, St. Louis product. Examining a number of these units and trying to uncover “mold twins” is one thing only correct “insulator nerds” might do, but that would most likely describe myself!

When seeking at a couple of examples of these insulators, in a random assortment there may well be no duplicate molds at all — every piece exhibiting lettering noticeably diverse from the others in alignment and spacing. But, in one more small accumulation, various mold duplicates could be discovered. A handful of examples are identified with a smooth base, lettered only “HEMINGRAY / No 9” on a single side, and those are believed to be the pretty initially No. 9’s made, shortly just before the 1893 patent officially went into impact. Some of those very same molds exist in both smooth-base versions and a version with sharp drip points and the “May two, 1893” embossed lettering.

All of the insulators photographed are from my individual collection. This trio of Hemingray insulators are still stained with carbon soot from their time spent in close proximity to a steam powered railroad line. Some collectors like to clean the insulators of this black residue but I do not touch them.

As is correct of most glass insulators of this earlier era, the fantastic majority are located in shades of aqua (blue-green). The earlier Script colors consist of, apart from typical aqua and light aqua, a variety of pastel tints. Right here is a general color list, despite the fact that I should make it clear it is NOT definitive or comprehensive!
