The CD 154 glass insulator was by far the most widespread style of insulator created by quite a few distinctive glass companies for telegraph distribution, and to a lesser degree for open wire phone distribution. Used along most railroads throughout North America. The Hemingray-42 may be the most mass created glass insulator in the globe, but this is why it is a single of my favorites. These are some of the colour variations I have found close to dwelling. Clear, clear-smoke, ice blue, blue, two shades of aqua, and green. In this shot the prime buckarm has four CD 230 Hemingray and Hemingray D glass insulators.

Cobalt blues were utilised mainly as line markers in Ellsworth, Kansas and close to Oklahoma City, OK. CD 162 signal insulators were made for phone and low voltage power distribution that have been developed 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 product from his competitors.

All of the insulators photographed are from my personal collection. glass insulators This trio of Hemingray insulators are nevertheless 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 do not touch them.

This particular bottle was made by Owens-Illinois in 1984, as indicated by markings along the decrease heel of the bottle . I hope this post will help some new, starting, insulator collectors get a new point of view on the Hemingray NO. 9 style that served on phone lines for so lengthy here in the United States. In at least one mold, the “9” below the name HEMINGRAY is truly an upside-down “G” stamp.

• As is accurate of most glass insulators of this earlier era, the excellent majority are located in shades of aqua (blue-green).
• Right here is a general colour list, though I must make it clear it is NOT definitive or comprehensive!
• In the latter half of the 19th century entrepreneurship was booming.
• But I know 1 insulator dealer who kept red marbles at his table when he had red CD 272's for sale.

Some locations had much more than 1 energy firm on a pole, so distinctive colors have been use to aid the lineman distinguish what line they were working on. Also, the poles used different types of circuits so distinct colors were used for the distinct circuits. A excellent example would be Kansas City, MO making use of cobalt, peacock, and electric blues on their street lighting circuits.

Two Blue Hemingray Insulators

Which is the way I tend to lean when contemplating the subject. It is to acquire a extra fantastic insulation than has been obtained by this arrangement, that our invention is directed. To accomplish this result, we mold or safe at the reduce 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 decrease edge of the insulator, is adequate, but when preferred, of course the inner shield D could be provided with a comparable series of teats.



For instance it could be HEMINGRAY • or a thing like No • 44. This list is an attempt to catalog known examples as this is anything beyond the official "guide". Mold quantity “33” on the base of an emerald green soda bottle made by Owens-Illinois, Inc. Millions of these sorts of “generic” non-returnable soda bottles have been created for many years.

A collection of 66 glass threaded pin type insulators from North America. Quite a few of these insulators have been made use of on telegraph poles for wire line Morse code communication. The index is lettered “HEMINGRAY / No 9” on the front skirt and “PATENT / May ” on the rear skirt. Fred's most significant influence on insulators would be his involvement with porcelain insulators.

I believe the soot adds exceptional character to the piece A telltale clue of the insulator's actual use throughout a bygone era. In this installment we'll take a appear at an fascinating but obscure corner of the antique glass insulator globe the drip point. Drip points always come up in conversations when I run into non-collectors who show me that 1 old Hemingray insulator they had laying about out in the barn or on a windowsill. Not also many persons know the goal of the tiny teeth ringing the bottoms of these prevalent insulators except collectors inclined enough to poke about and learn the history. I normally get a kick out of explaining this small piece of Hemingray lore when I have a chance.

Closeup of “EVO 1” style, No 9 sideThe “EVO 2” is a seldom-observed variant which is additional lightly engraved, the lettering with rather squared-off orientation and similar to the succeeding Prismic style. The Script embossing has a comparatively lightly-embossed top quality about the lettering. The “1893” date is normally crude with a noticeably “handwritten” appearance. I located 5 of these, the first ones in my collection. Discovered along the former Rock Island near Malcom, Iowa.

Now, it is extremely uncommon to even see any remnants of the old open wire phone lines. By 1970, most open wire phone lines were converted over to aerial cable or placed underground. The dark olive greens had been utilized along the NYCRR water level route through Sandusky, Ohio, and the towns of Conneaut, Ohio and Meadville, Pennsylvania. This pole got upgraded about ten years ago along with all the other poles in the alley. Following all the upgrades to the power grid, two neighborhoods in Fort Wayne about 10 years ago from these days in no way got the new upgrades. Sections of the Northside Neighborhood and little sections of Spy Run Neighborhood in no way got the upgrades, but that all changed about a year later where all the old poles got upgraded to newer poles.

Teal Green ? Cd 162 Hemingray No 19 Glass Insulato

It bears a vague resemblance to the Bass Clef sign as utilized in sheet music. The engraving in the molds was deep and the resultant embossing on the insulators is powerful and bold. This insulator was produced by the Hemingray Glass Enterprise in Muncie, Indiana. The CD 113 Hemingray style insulators had been made from the c1890's-1940's. The CD 113 was a extremely common style and millions have been produced by a handful of glass corporations with Hemingray producing the most. The peacock blues were mainly used on the street light circuits around Kansas City, MO and other compact towns in Missouri, although the dark cobalt blues had been used in the states of Kansas, Texas, and Ohio.

Root Beer Amber Hemingray Patent May Perhaps Two 1893 Petticoat Glass Insulator

So far, I have only noticed a single mold where the “9” is positioned straight below the “A”. The most popular placement is below the “G” or slightly to the proper or left of the G. Incidentally, a quantity 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 have been created for open wire telephone distribution.
