Aid W Hemingrays & Clear Insulators
So far, I have only observed one particular mold where the “9” is positioned directly beneath the “A”. The most common placement is below the “G” or slightly to the ideal 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 recognized as an exchange insulator that have been created for open wire telephone distribution.



Starting from the bottom of the pole the bottom buckarm have 5 signal form porcelain insulators with what looks like a 240 volt circuit top to 3 clients. Above that an old pothead that looks abandoned due to the three box-sort cutout fuses in the open position on the crossarm above. The two white glazed porcelain insulators are U-180's, most likely supporting an old six.6A series street lighting loop circuit. The top rated two buckarms appear to have several U-784 Hi-Top rated porcelain insulators, and two CD 219 Hemingray glass insulators which one can't be noticed. Hemingray have been one of the handful of glass firms that actually created diverse colors to designate diverse circuits on a pole.

A, is the body of the insulator created of glass, porcelain or other suitable insulating material. In the latter half of the 19th century entrepreneurship was booming. Inventors, businessmen and industrialists had been forging ahead at complete steam each attempting to outdo his competitors in the new and growing industrial primarily based economy of a young America.

The pole on the left has eight CD 219 Hemingray-660's, two CD 231.two Kimble-820's, and five CD 183 Hemingray-71's. Correct pole has six CD 231.2 Kimble-820's and two CD 183 Hemingray-71's. There have been 5 phone poles with glass insulators leading to an old farm residence. In this shot, the two glass insulators are CD 122 Hemingray-16s.

At the time this photo was taken, Bluffton, Indiana was still making use of the old 6.6A series street lighting loop, which only a handful of cities and towns were working with at the time. The street lighting circuits had been changed more than to contemporary parallel circuit system a few years following the photo was taken. Possibly no other glass insulator comes to thoughts extra than the Hemingray 42 when we feel of the glass telegraph/telephone insulator. Introduced in 1921, the  petticoat communication insulator ever produced. Gill's innovative notion to help rain water shed off the glass insulator.

Weird seeing a Hemingray-42 on a energy pole since they had been produced for telegraph service. https://umek.pro/company/production I hope this article will assistance some new, beginning, insulator collectors acquire a new point of view on the Hemingray NO. 9 style that served on phone lines for so long here in the United States. The embossing which seems on the insulators is "Patented April 25, 1899." The amber colors have been mainly applied in the state of Kansas with the orange ambers employed on the line markers in Ellsworth, Kansas. https://umek.pro/company/about-us

The "PROVO" name can be identified on four unique CD style insulators as No. , No.1 , No.2 , and No. 4 (CD 303.five). Rather than leave all of my Hemingray insulators outdoors I've brought some of them indoors and added some battery faux tea lights. Not sufficient light to read by but good ambiance in the living area in the evenings. There were a lot of CD 160 Hemingray-14's on a lot of of the poles downtown Hamler only. CD 160's are a smaller size of the CD 162 and nickname the "child signal." They had been a lot rarer to see along railroads. On this pole there ought to of been among of the CD 160's.

One particular variant has a really slightly narrower “bottom loop”, as if approaching on a “V” shape. The second type is the most prevalent, noticed on likely 70% or additional of these units. The short horizontal stroke of this G typically appears indistinct or “sloppy”. The No. 12 was typically utilised on phone “drop lines” extending from the back alley to individual houses and organizations. The effectiveness of this invention is highly questionable soon after all these years, but the patent was surely “hyped” to a excellent degree by Hemingray. A significant percentage of their insulators had been made with drip points for lots of years.

Many years ago, the open wire used with the two glass insulators was abandoned and a single-user aerial cable was added. Glass energy insulators are getting very rare to see up in service today. They were last created about six decades ago, and with all the upgrading going on. CL&P employed four diverse glass insulators on their neutral lines. CD 168 Hemingray D-510s, CD 218 Hemingray-660s, CD 230 Hemingray D-512s, and CD 272 Whitall Tatum 511As.



Also on the buckarm on the right is an isolation transformer for the series street lighting. The thought of a red glass insulator has captured the thoughts of collectors due to the fact the hobby began. When I was collecting in the 1960's, collectors wondered if a red insulator would ever be found. Even currently, if you speak to non-collectors at flea markets and antique shops, they will relate stories of red glass insulators being found...
