Inquiries And Values On Glass And Ceramic Porcelain Insulators

I've integrated the patent application letter beneath and it is interesting to read the reasoning behind the little "teats" as they were named by the inventors themselves. The “Stamp” molds are easier to tell apart from each other than the Prism molds are, just simply because of the normally erratic placement of the stamped letters. The mold engraver had excellent difficulty in stamping the characters in Precisely the similar position from mold to mold. “EVO” style embossings, which are rather really hard to come across, have been noticed in most of the exact same colors as the “Script” style. “EVO 1” can be identified by the oddly shaped “9”, shown right here.
Starting from left to correct the colors are cobalt blue, dark olive green, dark red amber, dark cobalt blue, olive amber, orange amber, 7-up green, peacock blue, and honey amber. The glass insulators are three CD 231.2 Kimble-820's and six CD 183 Hemingray-71's. The CD 183's on the bottom buckarm most most likely supported old 6.6A series street lighting loop circuits.
The pole on the left has eight CD 219 Hemingray-660's, two CD 231.two Kimble-820's, and 5 CD 183 Hemingray-71's. Right pole has six CD 231.2 Kimble-820's and two CD 183 Hemingray-71's. There were five telephone poles with glass insulators leading to an old farm property. In this shot, the two glass insulators are CD 122 Hemingray-16s.

Used, Hemingray Petticoat Patent May Possibly Two 1893 Glass

By 1895 he was getting a variety of porcelain firms make porcelain insulators to his styles produced for his manufacturing company he began in 1894. In 1898 he opened his personal porcelain insulator plant in Victor, New York and produced wet method porcelain insulators. Fred would go on to retire from his insulator manufacture in December 1904 but continued to have some influence for a few a lot more years. The CD 249 is a large energy insulator used for higher voltage power distribution with a rating up to 50,000 volts. The Hemingray Glass Organization in Muncie, Indiana made these Provo Type insulators in the early 1900's, and have been employed in service around the Pittsburgh, PA region. There are three unique designs of the letter “G” observed on the STAMP style No. 9s.

• A pal of mine has about 500 insulators that I just looked through.


• If you just looked at the marble, it was red glass without having a doubt.


• A close up of a CD 232 Hemingray-D-513 in service use along a rural road just outdoors Decatur, Indiana.


• It would have been embossed with "No 16" had they put the style on it back when it was produced.

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 don't touch them.

Green Cd 162 Hemingray Glass Insulator

These Mexican insulators are discovered in red amber, and are considerably more economical than some of the other reddish colored insulators shown in this report. Today, the truest "red" insulators are each recent commemoratives. The VTS CD 102 pony shown on the inside of the front cover comes in genuinely red glass. [newline]Some McLaughlin commemoratives, created in 1972, are a dramatic red color . But insulators created for actual service on lines look to have only be identified in "reddish" colors.

Glass

When seeking at a couple of examples of these insulators, in a random assortment there might be no duplicate molds at all — each piece exhibiting lettering noticeably diverse from the other people in alignment and spacing. Yet, in yet another compact accumulation, quite a few mold duplicates could be discovered. glass insulators A handful of examples are identified with a smooth base, lettered only “HEMINGRAY / No 9” on one particular side, and these are believed to be the incredibly 1st No. 9’s created, shortly just before the 1893 patent officially went into impact. Some of these identical molds exist in each smooth-base versions and a version with sharp drip points and the “May two, 1893” embossed lettering.
what are glass insulators Yet another variant has a letter “M” placed to the left of “No 9”, almost certainly resulting from the mold worker starting to engrave “MAY” on the second line, and then realizing his error. Two examples, each from the identical exact Hemingray No 9 “STAMP” style mold. The a single on the suitable is the wider version (produced immediately after the mold was re-tooled). It may well have been manufactured months or years following the a single 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 through this time.

The amber colors had been mainly employed in the state of Kansas with the orange ambers applied on the line markers in Ellsworth, Kansas. Unique ambers were also discovered in the pacific northwest like Spokane, WA and other smaller towns throughout Idaho and Montana.
