Insulator Historical Timeline

I consider the soot adds one of a kind character to the piece A telltale clue of the insulator's actual use in the course of a bygone era. In this installment we'll take a appear at an interesting but obscure corner of the antique glass insulator planet the drip point. Drip points always come up in conversations when I run into non-collectors who show me that a single old Hemingray insulator they had laying around out in the barn or on a windowsill. Not as well numerous people today know the purpose of the little teeth ringing the bottoms of these common insulators except collectors inclined enough to poke around and learn the history. I constantly get a kick out of explaining this small piece of Hemingray lore when I have a opportunity.
This specific bottle was created by Owens-Illinois in 1984, as indicated by markings along the reduce heel of the bottle . I hope this write-up will help some new, beginning, insulator collectors get a new point of view on the Hemingray NO. 9 style that served on phone lines for so extended right here in the United States. In at least 1 mold, the “9” beneath the name HEMINGRAY is essentially an upside-down “G” stamp.

• By 1892 Fred started promoting electrical and telegraph supplies, most of which were made to his specifications, with the Brookfield Glass Organization and also the Hemingray Glass Corporation creating the glass insulators.


• Incidentally, a number of the purple colored units are from molds in which the “9” is positioned underneath “IN” or “N”.


• I’m sorry but this write-up is mostly about the oldest key form of “No 9” insulator which is classified in the value guides as embossing index number . https://www.google.co.vi/url?q=https://etextpad.com/spjmri03x6


• All insulators have the Hemingray / Patent May possibly 2ND 1893 on the front embossing.

One of the most prevalent kinds of pony insulators was made by Hemingray Glass Companyof Muncie, Indiana, and that was their “Number 9” style. CD 302 Hemingray energy insulators nonetheless in service use in Ohio just after additional then one hundred years of service duty. It is really rare to see massive colored glass pintype power insulators nevertheless in service use today. The CD 232 Hemingray D-513 was produced by the Hemingray Glass Company in Muncie, Indiana in the 1930's and 40's.

Assist W Hemingrays & Clear Insulators

Which is the way I tend to lean when contemplating the subject. It is to receive a extra excellent insulation than has been obtained by this arrangement, that our invention is directed. To accomplish this result, we mold or safe at the lower edge of the flaring bell-mouth of the insulator, a series of lugs or teats b, b. We come across in practice that a single row of these teats arranged on the reduced edge of the insulator, is sufficient, but when desired, of course the inner shield D could be supplied with a equivalent series of teats.
A CD 220 Hemingray-670 power insulator still in service use soon after 80 years of service in northern Indiana. The Hemingray Glass Corporation in Muncie, Indiana was the largest producer of this CD style of insulator. Millions upon millions were generate from 1921 to the early 1960's.
So far, I have only noticed a single mold where the “9” is positioned directly beneath the “A”. The most widespread placement is beneath the “G” or slightly to the correct or left of the G. Incidentally, a number of the purple colored units are from molds in which the “9” is positioned underneath “IN” or “N”. A pony style of insulator known as an exchange insulator that had been developed for open wire telephone distribution.

Hemingray May Perhaps Two 1893 Insulator Smaller Version

These Mexican insulators are discovered in red amber, and are considerably extra reasonably priced than some of the other reddish colored insulators shown in this post. These days, the truest "red" insulators are each current commemoratives. https://www.google.com.ag/url?q=https://helpful-flamingo-gml1c7.mystrikingly.com/blog/were-not-sure-why-someone-would-take-action-vandal-shoots-out-b-c-power-line The VTS CD 102 pony shown on the inside of the front cover comes in actually red glass. [newline]Some McLaughlin commemoratives, created in 1972, are a dramatic red color . But insulators made for actual service on lines seem to have only be located in "reddish" colors.
Some collectors had been buying them and turning them into candlesticks. We do not recall ever supplying a equivalent instance in more than five decades of hobby involvement, so are of the belief it really is a fairly hardly ever encountered and really desirable color variant. The base is marked with the “H more than smaller a” logo. “Scales” emblem applied on containers created for McKesson & Robbins. This is on the base of a smaller green glass jar, probably for an ointment.
For instance it could be HEMINGRAY • or something like No • 44. This list is an try to catalog identified examples as this is one thing beyond the official "guide". Mold number “33” on the base of an emerald green soda bottle made by Owens-Illinois, Inc. Millions of these forms of “generic” non-returnable soda bottles have been produced for lots of years.
The "PROVO" name can be discovered on 4 distinct CD style insulators as No. , No.1 , No.two , and No. 4 (CD 303.5). Rather than leave all of my Hemingray insulators outdoors I've brought some of them indoors and added some battery faux tea lights. Not enough light to read by but good ambiance in the living area in the evenings. There have been a lot of CD 160 Hemingray-14's on several of the poles downtown Hamler only. CD 160's are a smaller size of the CD 162 and nickname the "baby signal." They were a lot rarer to see along railroads. On this pole there have to of been in between of the CD 160's.
A collection of 66 glass threaded pin variety insulators from North America. Numerous of these insulators had been utilised on telegraph poles for wire line Morse code communication. The index is lettered “HEMINGRAY / No 9” on the front skirt and “PATENT / May perhaps ” on the rear skirt. Fred's most significant influence on insulators would be his involvement with porcelain insulators.
