Relics of Early Communication

 

QUESTION: I recently purchased a box of glass insulators, like the kind used on telephone and electric poles. Several have little white specks in the glass. I bought them because of their beautiful colors, but do these things have any value as a collectible? And just how were they used?

ANSWER: There’s nothing like the beauty of colored glass, especially when placed in a window where the sun can shine through it. Many people collect these glass electrical insulators for just that reason. But some, especially retired linemen, collect them because they’re a part of the history of telecommunications.

The first electrical systems to make use of insulators were telegraph lines; but directly attaching wires to wooden poles gave very poor results, especially during damp weather. Ezra Cornell invented the insulator in 1844 as a means of protecting electrical wires front the elements and reducing the loss of current from the wire to the ground. As technology developed, power and telephone companies needed more insulators. 

The earliest insulators had unthreaded pin holes. Because linemen simply pressed them onto a tapered wooden pin, extending upwards from the crossarm of an electric pole, they didn't stay on very well since the wires contracted and expanded in the heat and cold. When Louis A. Cauvet improved the insulator by patenting the threaded pin hole type in 1865, he sold his invention to Brookfield Glass Company of Brooklyn, which remained a major producer of insulators until 1922.

Though threaded pin holes helped insulators stay put, moisture still presented a problem since wet glass served as a conductor. In 1893, the Hemingray Company, another major manufacturer, obtained a patent for insulator "drip points." These bumps, which line the outside bottom rim of the insulator skirt,  helped prevent shorts by causing moisture to drip off. The earliest points were sharp but these were easily broken, leading to the manufacture of more rounded ones.  must have discovered that these really didn't work, since they eliminated them from later models. However, other companies continued to make insulators with drip points.

Porcelain insulators began to replace glass examples in the early 20th century, particularly on high voltage lines since glass insulators only worked on lines handling up to 60,000 volts.. By the late 1940s, only a few producers of glass insulators remained, by 1969, Kerr Manufacturing was the only company still making them. 

Manufacturers produced glass Insulators in a variety of colors and types of glass. They used remnants of window or bottle glass for earlier ones. Most companies made insulators only as a sideline,  pressing them out of whatever kind of glass happened to be available. Because of this, objects like nails, screws, coins, and bits of furnace brick would get mixed into the glass. Collectors call the little white furnace brick bits rocks. Some makers, like Hemingray, would cull out these blemished pieces, but others like Brookfield Company would just sell the blemished pieces along with the good ones.

The most common insulator colors are clear and light bluish-green or aqua. Other colors include sun-colored amethyst, green,  milk glass, royal blue, cobalt, amber and Carnival glass. The only color not made in glass is red, because red requires gold as a colorant. The most popular colors are royal blue and cobalt, with amethyst a close second. Insulator makers originally produced purple ones, ranging from  light lavender to deep amethyst, from clear glass. Manganese, used to clarify the glass, turned the glass purple after being exposed to the sun’s ultraviolet rays. After the start of World War I, manganese became scarce since it was needed for arms production. Manufacturers switched to selenium, which the sun turned to the color of wheat.

Common clear and aqua insulators sell for as little as a dollar each. But prices climb steadily for rare ones such as the Buzby or the Twin Pin. Aqua ones made by the Jeffrey Manufacturing Company can sell for as much as $125 each while a threadless Canadian insulator, also known as a snow cone, can sell for about $2,000.

Bringing Light to the Farm

QUESTION: The other day I was going through some old things that belonged to my father and came across what looks to be an almost brand-new Coleman lantern still in its box. Since I’m not much of a camper myself, I wondered if people collect these lanterns and if they have any value.

ANSWER: According to your photo, your lantern looks to be one made in the late 1940s. Soldiers who had fought in World War II and had used special field stoves designed and made by the Coleman Company were familiar with their products. So as they settled down to have families, they saw the need for vacations. Car camping became very popular, as these new families loaded up their station wagons and headed out to explore America.

Anyone who has gone camping knows the glow emitted from campgrounds as campers sit around their tables having dinner by the light of a Coleman lantern. Promoted as the "sunshine of the night," these lanterns have long since become essential gear to car campers.

The incandescent electric light, invented in 1879, was a long way from reaching rural America in 1900, when William C. Coleman, an itinerant salesman, first sold indoor pressurized gasoline units, which he called Efficient Lamps. Coleman had poor eyesight, and the standard lamp of that time burned kerosene and produced a smoky, flickering, yellowish light. The steady white light produced by his new lamp enabled him to read even the smallest print. Two years later he bought the manufacturing rights for the lamp, and by 1905 he had begun producing them in his Wichita, Kansas, factory.

By1909, Coleman had improved his 300-candlepower, portable table so that it provided light in every direction for 100 yards and could light the far corners of a barn. Single handedly, he changed the way farmers worked and thus increased their productivity. His lamp became a staple in rural America, eventually transforming the local company into a national one on which people depended.

Coleman’s initial lamp featured decorative brass or nickel-plated elements that arched up around the lantern´s glass shade, providing an upper loop for hanging or grasping the lantern for barn use. Later, he designed ones with bulbous bases that could sit on tables. And like other lamps at the time, some had colorful glass shades with elaborate designs around the edges.

Coleman’s first lamps for indoor use differed from oil lamps. Each had a pressure tank that acted as its base, replacing the oil lamp's fount or reservoir. In place of the oil lamp's chimney and wick, Coleman’s lamp used a generator, which vaporized air-forced white gas. The burning vapors ignited a mantle of loosely woven fabric. Both of these features helped Coleman lamps produce 20 times more light than oil wick lamps.

By 1914, the first self-contained, portable Coleman lanterns for outdoor use—the ones so familiar to campers today—appeared on the market. He enlarged the fount so that it stored two quarts of white gas, enclosed the generator and mantles in a wind- and bug-proof glass globe, and added a bail for easy carrying and hanging.

Coleman designers continued to improve their lanterns and by the 1930s, many came with housings in   different colors. The tops of some of the lamps of this period had a green finish which eventually became the signature look of Coleman products. The company also supplied lanterns to the National Forest Service, some of which bore the familiar “NFS” insignia.

From the 1940s on, Coleman lanterns featured a forest green finish combined with shiny nickel-plated brass elements. The upper and lower parts of one of the company’s most popular and long-running lanterns, the Model 200A, produced from 1952 through 1983, are bright red.

Most people use Coleman lanterns for camping. They’re as prized now as they were decades ago for chasing darkness from a campsite. When night falls, a few strokes on the pump primes it for action. And at the touch of a match the lantern throws its magic circle of light in a 360-degree arc.

Starting in 1901, Coleman has produced close to 50 million gas lanterns. The long history and the range of styles and models makes the Coleman lantern a popular collectible that’s affordable for most collectors. A Coleman lantern can sell today for $20 to $400, depending on its age, condition, and rarity.

The Fair Where Electricity was the Star Attraction

QUESTION: I love to browse the small items found in showcases at antique coops and at flea markets. Recently, I came across a matchsafe with a cigar cutter that came fro the Pan-American Exposition in Buffalo, New York. I’ve never heard of this. Could you tell me more about it? Is this matchsafe something I want to hold onto?

ANSWER: You’re not alone when it comes to knowing much about this world’s fair. Unfortunately, all the hoopla about the technology exhibited at the fair was overshadowed by a traumatic incident—the assassination of President William McKinley. And while this happened towards the end of the fair at the beginning of September, it undermined the importance of this event.

For six months in the summer of 1901, all the world came to Buffalo, N.Y ,to see the wonders of the new century and to celebrate the unity of the countries of North and South America during the Pan-American Exposition. More than 8.3 million people came to the exposition. Visitors called it “Doing the Pan.” For most, it was the trip of a lifetime. For one person, President William McKinley, it was his last. While canals and gardens dazzled them, the midway seduced them. The buildings, covered in the new electrical lights, kept them in awe.
                   
President William McKinley was shot by anarchist Leon Czolgosz while he was shaking hands with visitors in the Temple of Music on the fairgrounds on September 6, 1901. He died eight days later.

Every country in the Americas participated. The exposition Vacant land at the northern edge of Buffalo was transformed into a Spanish Renaissance style wonderland. Electric light bulbs outlined all of the major buildings. The 391-foot Electric Tower alone boasted 40,000 bulbs. At dusk, visitors gazed in awe at the display of electrical lighting, a novelty at that time.

The fair’s theme was to unite the Americas. Prior to the opening, the exposition’s organizers held a contest for the design of the logo. Raphael Beck, an artist from Lockport, a city on the Erie Canal northeast of Buffalo, won the $50 prize with his entry. The logo featured a map of the western hemisphere. North America was depicted by a fair-haired woman and South America depicted by a dark-haired woman. The women joined hands to form Central America.

The Pan-American Exposition produced thousands of souvenirs which collectors seek today. Many souvenir items were made picturing the buildings and other features of the fair. The Electric Tower pictured on your letter opener was the tallest structure at the fair and often appears on souvenir items.   Many of the souvenirs were pans, said Boyd. One frying pan had a button on the side. When the button is depressed, the lid opens and one sees a tiny buffalo standing in the middle of the pan.

Many of the souvenirs were made of aluminum, a new metal introduced at the Columbian Exposition in 1893. By the time of the Pan-American Exposition, aluminum had become a major industry in nearby Niagara Falls. After President McKinley's death, people bought presidential memorials made of aluminum.

Among the most popular souvenirs were postcards, of which about 500 different ones have been identified. Pan-American stationery allowed exposition visitors to send letters. The Pan-American logo, with or without a buffalo, appeared on the envelope.



Nearly every day was a special day at the Pan-American Exposition, and sponsors of various ceremonies and special days sent invitations. Many of these invitations as well as the envelopes have survived.

Post offices sold special issue stamps in denominations of 1, 2, 3, 4, 5, 8 and 10 cents. These stamps weren't to be used as postage and had to be specifically requested by customers.

And visitors could find free samples of food or beverages or free souvenirs in the Manufacturers & Liberal Arts Building, free sample soap bars in the Larkin Building, free machine-woven ribbons, bookmarks, etc. These, in addition to free brochures and advertising cards, enabled those who could afford only the costs of getting to the Exposition to carry away remembrances of their experience.

The New Kid on the Block

QUESTION:  This lamp has been in the family for reportedly over 100 years. It does not have a signature of any kind. The lighting fixture itself had been missing and my father installed a new one some years back. Is there any way to date and identify the maker of this piece?

ANSWER: Looking at your hanging lamp, it doesn’t look to be over 100 years old. Most likely it dates from the 1920s, maybe slightly earlier, based on the configuration of the socket frame.

Although Thomas Alva Edison is often given the credit for inventing the electric light bulb in 1879, the actual creation can be credited to several people, each of whom improved upon the basic concept.

In 1875, Henry Woodward received a patent for an electric light bulb. And four years later, Edison and Joseph Wilson Swan received a patent for a carbon-thread incandescent lamp. Edison initially worked with J. P. Morgan and a few privileged customers in New York City in the 1880s to light their homes, pairing his new incandescent bulbs with small generators.

In 1878, Thomas Edison began serious research into developing a practical incandescent lamp and on October 14, 1878, Edison filed his first patent application for "Improvement In Electric Lights." So it could be said that Thomas Edition created the first “commercially practical” incandescent light.

The first electric lamps, however, were nothing more than electrified gas lamps. Often the manufacturer didn’t know which sockets to use, so they put in a variety in the same lamp, and the wiring left a lot to be desired. Safety wasn’t even thought of much back then. Even the light bulbs were different. There was no standardization like we’ve known through the latter part of the 20th century and into the 21st. The electric lighting industry took a while to take off.

Back at the turn of the 20th century, electricity was just beginning to find its way into the homes of average Americans. Before that, it was mostly a new toy of the wealthy.

A number of improvements occurred as the 20th century dawned. Peter Cooper Hewitt created the first commercial mercury-vapor lamp in 1901. Alexander Just and Franjo Hanaman invented the tungsten filament for incandescent light bulbs. In 1904.

By 1913, Irving Langmuir had discovered that inert gas could double the luminous efficacy of incandescent light bulbs. Burnie Lee Benbow patented the coiled coil filament in 1917. But the most far-reaching improvement was the production by Junichi Miura of the first incandescent light bulb to use a coiled coil filament in 1921. Finally, in 1925, Marvin Pipkin invented the first internal frosted light bulb.

All these improvements had lamp makers reeling. Once the electric light bulb had finally been stabilized, they saw the opportunity to use this constant source of even light to their advantage.

As household electricity became increasingly common and the light bulb more stable and long lasting, so lamp manufacturers started paying attention to the art of lighting indoor spaces. Shades gave lamp makers an opportunity to shine a light on their sense of aesthetics, whether it was to create a romantic background glow or an eye-catching centerpiece.

Lamp makers of the early 20th century looked to the Art Nouveau style, with it plant and animal motifs, to inspire their designs. Manufacturers were soon creating shades in a spectrum of colored glass, either hand-cut into complex patterns or blown into natural forms like flowers.

Louis Comfort Tiffany designed and made some of the most recognizable Art Nouveau lamps, including shades made from iridescent Favrile glass or intricate stained glass mosaics. Originally conceived by designer Clara Driscoll, Tiffany’s Dragonfly lamp shade is possibly the Studio’s most famous, featuring minuscule glass pieces in each detailed dragonfly wing. Such shades were created using a leaded-glass technique the company perfected for stained-glass windows. Capitalizing on the Tiffany trend, companies like Duffner & Kimberly, Gorham, and Seuss also created ornate stained-glass shades in the early 20th century.

Because electricity for mass use was in its infancy in the first decade of the 20th century, no two lamp manufacturers used the same electrical components. Although   the sockets in your lamp have been replaced, the lamp, itself, is more sophisticated than those produced say from 1900 to 1910. A lot of manufacturers produced lamps like this. The thickness of the glass and the soldering of the lead came indicated that this lamp was made in a small factory, most likely by hand. But without a signature of any sort, it’s hard to tell exactly which company produced it.
