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

The town of Troy, Ohio nonetheless had a lot of this old power distribution throughout the town. This shot shows four in service with both the Ohio and Muncie Variety embossing on the reverse side. All insulators have the Hemingray / Patent May possibly 2ND 1893 on the front embossing. This shot shows a close up of both the front and reverse embossing on the insulators. On the old poles the I&M lines were up on the best crossarms while the CL&P lines would be on the bottom crossarms. At times down an alley the I&M poles would be on 1 side with the CL&P poles on the other side.

I’ve included the patent application letter beneath and it is interesting to read the reasoning behind the small “teats” as they have been called by the inventors themselves. The “Stamp” molds are a lot easier to tell apart from each and every other than the Prism molds are, merely due to the fact of the often erratic placement of the stamped letters. The mold engraver had excellent difficulty in stamping the characters in Precisely the identical position from mold to mold. “EVO” style embossings, which are rather difficult to find, have been noticed in most of the very same colors as the “Script” style. “EVO 1” can be identified by the oddly shaped “9”, shown right here.

A lot of of the pieces in this picture have due to the fact moved on to other collections . Are you waiting for a fantastic bidding chance, there is what seems to be a “1” on the top. Four mclaughlin glass in quite good situation, no harm or put on. For Valentine’s, Crown Jewels presents “red” insulators identified in the hobby.

Also on the buckarm on the right is an isolation transformer for the series street lighting. The concept of a red glass insulator has captured the thoughts of collectors because the hobby began. When I was collecting in the 1960’s, collectors wondered if a red insulator would ever be located. Even right now, if you talk to non-collectors at flea markets and antique shops, they’ll relate stories of red glass insulators becoming identified…

• It was the density of the glass that made the insulator look more amber than red.
• That implies for $92.40 you could have ordered one particular-thousand cobalt blue insulators…
• The street lighting circuits have been changed over to modern day parallel circuit method a few years following the photo was taken.
• The CD 113 was a quite common style and millions have been made by a couple of glass businesses with Hemingray making the most.

Beginning from the bottom of the pole the bottom buckarm have 5 signal form porcelain insulators with what looks like a 240 volt circuit major to 3 buyers. Above that an old pothead that appears abandoned due to the 3 box-form cutout fuses in the open position on the crossarm above. The two white glazed porcelain insulators are U-180’s, likely supporting an old six.6A series street lighting loop circuit. The top two buckarms appear to have several U-784 Hi-Major porcelain insulators, and two CD 219 Hemingray glass insulators which one can not be observed. Hemingray have been a single of the few glass companies that in fact created distinct colors to designate distinct circuits on a pole.

Featured Inquiries And Values On Glass And Ceramic Porcelain? Insulators

The CD 154 glass insulator was by far the most common style of insulator created by lots of unique glass businesses for telegraph distribution, and to a lesser degree for open wire phone distribution. Applied along most railroads all through North America. The Hemingray-42 might be the most mass created glass insulator in the globe, but this is why it is one particular of my favorites. These are some of the color variations I have found close to home. Clear, clear-smoke, ice blue, blue, two shades of aqua, and green. In this shot the best buckarm has 4 CD 230 Hemingray and Hemingray D glass insulators.

A nice old pole with old pothead, box-type cutout fuses, and insulators, each porcelain and glass. The April 25, 1899 patent was issued to Vernon G. Converse of Pittsburgh, PA for a design patent for a power insulator assigned to the Hemingray Glass Company. This was implemented in the CD 282 and 283 and later copied by U-372. CD 272 WHITALL TATUM. Compared to the red commemorative, the Whitall Tatum hardly looks red at all.

It would have been embossed with “No 16” had they place the style on it back when it was made. From personal expertise, I can assure you that not all those drip points have been intact up on the poles. My guess is that they often had been chipped or fell off prior to they ever even went up. An insulator, offered with a series of teats at the reduced edge of the insulator shield, to attract and collect at their points the drops of water operating down the outer surface of the insulator, substantially as described.

Cd 162 Brookfield Glass Insulator Lot Of Three

All three of the actual insulators shown above have been created in the second quarter of the 20th Century. It was a time when makers of glass insulators were possessing to compete with porcelain insulator makers for marketplace share. A lot of low voltage glass insulators made during this period have been formed in dark colored glass to compete with similarly colored porcelain items. The Price Guide lists D-512’s in red amber at $50 – $75.

Enable W Hemingrays & Clear Insulators

The density of the glass is such the red tones are difficult to bring out. K Hv With High Voltage power line insulators Up Close YouTube. I feel Spirit Bear told me the date refers to the teeth at the bottom of the insulator. This a single is a bit slimmer and smaller sized than other examples I have observed. Most clear insulators are from the 1930s and later.

The story of the drip point is suitable out of that era. A buddy of mine has about 500 insulators that I just looked via. These insulators had been really well known right here in the States about 20 years ago, and sold well.

Beginning from left to appropriate 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 3 CD 231.two Kimble-820’s and six CD 183 Hemingray-71’s. The CD 183’s on the bottom buckarm most likely supported old 6.6A series street lighting loop circuits.
