• I do have a handful of and I have 2 HEMINGRAY NO 9 insulators that came from Western Union Telegraph.
• For further data see our copyright claims page.
• The brushed nickel rectangular wall plate measures 5″ x 7 three/8″.
• Most insulators will respond nicely to cleaning with BKF, despite the fact that some may well not.
• Clear glass was applied primarily soon after about 1935.

Hundreds of various designs had been created over the years, and insulators are identified with a wide variety of embossed names, initials, patent dates, and other markings. This set of glass insulators is in incredibly good vintage condition. The insulator is embossed with Armstrong, Produced in the USA.

R-Worth is a measure of insulation’s capacity to resist heat flow. (The greater the R-Worth, the much better the thermal functionality of the insulation) The recommended level for most attics is to insulate to R-38 or about ten to 14 inches, based on insulation type. Most of these insulators had been made by Armstrong . The base is marked with the “H over smaller a” logo. Can you give me some hints as to where I can discover insulators/not from antique shops/flea markets. I mean out in the wild, if you know what I mean.

List Of Glass Factories That Manufactured Insulators

Some insulator collectors use lye as a cleaner, but I do NOT personally recommend it unless you are Very, Incredibly careful and take ALL precautions as directed on the item label. Railroads, trains, and telegraph lines and insulators have had a extended history of being interconnected. Huge numbers of old photographs of railroads, trains and railroad-related scenes from across the United States show the telegraph lines with insulators in place – in their “original habitat”, so to speak. And contemporary model railroading layouts sometimes include things like miniature telegraph poles with tiny “insulators” to support recreate the “look” of an earlier era.



Thanks for the info, I will analysis and evaluate in detail as time permits. It appears that my No 9 insulators are of the dark aqua color and they are in quite good shape. They are also marked with a patent date of May perhaps two, 1893 and I also have the wooden posts for the insulator to screw onto.

UMEK In the course of the 1960s, 1970s and 1980s a lot of of these lines had been dismantled as technology advanced. Nowadays, a couple of lines employing glass insulators are nevertheless in service, but are only a tiny percentage compared to the heyday of open wire communication. Your two Hemingray style #9 insulators could either be CD #106 or #107. #106 "was a standard style that replaced the CD 102 for modest signal lines for both telephone and telegraph." The #106 is a "pony" insulator, pony being a "nickname for a quantity of smaller sized designs of insulators".

This series of nine prints, utilizes the same quantity of glass insulators that were identified and dug up from the ground by the artist even though walking by means of the coulee on his grandparent’s farm in southwest Saskatchewan. The pictures for this series were generated by 1st laying the person glass objects on sheets of photosensitive film and exposing them to light in a darkroom. These films have been created then exposed onto lithographic plates and printed by the artist on a press. On some companies’ solutions, extra than one style of lettering can be identified.

To totally cover your attic floor with insulation out to the eaves you want to set up rafter vents . Comprehensive coverage of the attic floor along with sealing air leaks will make sure you get the best performance from your insulation. Rafter vents guarantee the soffit vents are clear and there is a channel for outside air to move into the attic at the soffits and out through the gable or ridge vent. Porcelain cable and glass signal insulator combination.

See our other LED insulatorlight Sconces for colors and sizes. From time to time an person mold can be identified by studying and comparing insulators that have been made from it more than a considerable stretch of time. Modifications in the mold, such as re-cut (re-tooled) engraving, repair, or the addition or erasure (“blotting out”) of the engraving can be found upon really close inspection of the insulator. As a result, the comparison I’ve created to the coin collecting hobby, with the a lot of slight variations in coin die style facts, as revealed under close scrutiny by significant collectors.

Armstrongs Dp 1 Produced In The Usa 6 68 Glass Railroad Insulator

This specific bottle was created by Owens-Illinois in 1984, as indicated by markings along the decrease heel of the bottle . Once again, it depends on a combination of traits like degree of scarcity, situation, demand, age, shade of color, attractiveness, and other elements. Broken insulators, speaking strictly of monetary value, in most situations are worth only a small percentage of the worth of an otherwise identical “Very near mint” piece. All insulators, glass and porcelain, in my opinion, have some value.



Our collection database is a operate in progress. We may well update this record based on additional investigation and review. Find out far more about our strategy to sharing our collection online. The attic is the easiest location to add insulation to strengthen your comfort and the energy efficiency of your house.

“Woody” Woodward, an early pioneer, researcher and author in the field of collecting glass insulators. The CD numbers fundamentally recognize insulators by their shape and profile, regardless of precise embossed markings, glass colour, or base kind. As time went on, networks of “open wire” telegraph lines, and later, telephone lines, were developed and constructed all through the country, and these lines needed the installation of insulators.

By the way, there ARE authentic purple glass Hemingray No. 9 insulators, but they date from the late 1890s or very early 1900s and do not have the same lettering arrangement as your comparatively modern number 9. All authentic purple Hemingray No. 9s have the embossing “HEMINGRAY / NO. 9” on the front and “PATENT / May perhaps ” on the reverse. Click here to check out my page on the so-referred to as “Crackle Glass” insulators. Vintage Armstrongs Glass Phone Line listing is for vintage threaded glass in very good shape no key damage signs of normal put on and tear.
