January 31 is Scotch Tape Day

January 31, 2017/2 Comments/in January

Today is Scotch Tape Day and celebrates the invention of cellophane tape in 1930. The story begins in the early 1920s at Minnesota Mining and Manufacturing, now known as 3M, which made only sandpaper at the time. Richard Gurley Drew, a banjo-playing college dropout hired as a research assistant, soon changed the course of the company’s history.

While delivering sandpaper samples to an auto body shop, Drew noticed painters’ frustration with the tape they used to mask car parts. Overly sticky, it ripped off bits of paint when removed, ruining the detail and forcing them to start over. He made it his goal to find a solution to their problem.

For the next few years, Drew experimented until he found the perfect combination of treated crêpe paper, cabinetmaker’s glue and glycerin. It adhered well yet stripped off easily without taking paint with it when removed. Automakers immediately recognized its value and began placing orders for it. The tape was marketed as Scotch Masking Tape in 1925.

Drew rose quickly through the ranks. In 1929, he struck upon the idea of using DuPont’s recently invented cellophane to make transparent tape. Cellophane was a moisture-proof material used to wrap and present baked goods and grocery items. Its only drawback was the difficulty of sealing packages securely and attractively. Drew hoped to develop tape that would blend with the wrap.

The machinery used to apply adhesive to masking tape was ill-equipped to deal with cellophane, which curled and ripped. The amber glue used on masking tape looked terrible on a transparent surface. Drew and his team had to design new machines and a new clear adhesive made from a combination of oil, rubber and resins.

The resulting Scotch Cellulose Tape was introduced in 1930. By that time, DuPont had already developed a new type of cellophane that could be sealed with heat, negating the need for tape. Despite the fact that Drew’s invention missed its target market and debuted during the Great Depression, the adhesive tape sold well to thrifty customers.

In fact, the desperate times may have spelled success for Scotch tape when other products would have failed. Even the racial slur the name is supposedly based on may have helped boost its sales. Scottish people were considered stingy. It was an ethnic stereotype that served 3M well: when money is scarce, stinginess is a virtue and a “cheap” product is a smart buy.

3M later promoted the legend with ads featuring “Scotty McTape,” a cartoon mascot who repeated the story that in 1925, auto painters told a 3M rep (presumably Drew) to go back to his “Scotch” bosses and tell them to put adhesive all over the tape. That’s unlikely since 3M didn’t make tape at the time and, in any case, the problem for the painters was that the adhesive was too strong.

Soon Scotty McTape was declared a member of Clan Wallace and began wearing its red tartan (and Wallace Hunting green plaid.) In the early 1970s, it was decided that McTape was no longer an effective marketing tool and the character was retired. The casual racism of Scotch tape’s name has been forgotten. Dispensers decorated in plaid are purchased every day with no awareness of their association with the clan of William Wallace, also known as Braveheart.

Richard Drew died in 1980 and was posthumously inducted into the Inventors Hall of Fame for U.S. patent number 1,760,820. While working for a sandpaper manufacturer, he invented a tool that has become an essential part of our lives. The next time you reach for adhesive tape, at home or the office, take a moment to imagine life without it. We can’t but, thanks to Mr. Drew, we don’t have to.

Happy Scotch Tape Day!

January 28 is National Kazoo Day

January 28, 2017/0 Comments/in January

Today is National Kazoo Day when kazoo players celebrate the long history of the instrument in America.

No one knows the exact date of the kazoo’s invention. A popular story holds that it was designed in the 1840s by an African-American man named Alabama Vest.

German clockmaker Thaddeus Von Clegg constructed a prototype which Vest introduced at the 1852 Georgia State Fair as the “Down-South Submarine.”

The closest we can get to verifying that account is to confirm that a state fair did occur in Macon, Georgia in 1852.

The modern metal kazoo was patented by George D. Smith of Buffalo, New York, on May 27, 1902.

We don’t know why it wasn’t mass-produced until a dozen years later. The factory, which became known as the Original Kazoo Company, now operates a museum open to kazoo fans who are willing to make the pilgrimage to Eden, New York.

Down south? The Kazoo Museum in Beaufort, South Carolina, opened in 2007, has a “collection of nearly two-hundred unique kazoo-related items.” It’s located in a kazoo factory on 12 John Galt Road, an address sure to delight Ayn Rand fans.

Budding kazooists should keep in mind that the kazoo is a membranophone, which modifies the player’s voice via a vibrating membrane. Players must hum, not blow, into the kazoo, varying pitch and volume to produce different sounds.

Because no advanced musical training is required, a player has the potential to become a virtuoso almost immediately. That fact may also be what keeps the kazoo from getting the respect it deserves.

Kazoo lovers across America are trying to change that with the Keep America Humming Campaign to Make the Kazoo the National Instrument. Campaign founder Barbara Stewart says:

“We have a national bird, a national song, and a national debt. Why not kazoo as a national instrument?” Why not?

Happy National Kazoo Day!

January 27 is Thomas Crapper Day

January 27, 2017/1 Comment/in January

Today is Thomas Crapper Day and commemorates the death, in 1910, of the man widely believed to have invented the flush toilet. Although that is, as they say, crap, Crapper was a shrewd marketer, leveraging his status as plumber to the British royal family to popularize indoor plumbing. He owned the first showroom of bathroom facilities and publicized the toilet at a time when no one spoke of such “necessities.”

Crapper is one small part of the largely untold history of the device that transformed the world. Humans have been building indoor plumbing for millennia. Excavations have shown evidence of flushing toilets dating back as far as 2600 B.C., during the mature Harappan phase of the Indus Valley Civilization.

John Harrington (also spelled Harington) invented a version in 1596 with a cord that, when pulled, would allow a rush of water from the “water closet,” flushing away waste. He installed one at his home and also built one for his godmother, Queen Elizabeth I. He called it the Ajax as a play on”jakes,” a slang term for toilet in use at the time. He may be the reason we sometimes call it a “john.”

An author, Harrington wrote “A New Discourse upon a Stale Subject: The Metamorphosis of Ajax.” Superficially, its subject was his invention; in truth, it was a thinly-veiled allegory about political stercus (manure) poisoning the state. The book got him banished from court for a time, and the queen referred to him as her saucy godson.

(Side note: A scent called Stercus was introduced at Smell Festival 2014 in Bologna, Italy. The perfumer named his brand Orto Parisi to honor his grandfather, who fertilized his garden with his own excrement. The bottle was displayed on a slab of dried, pressed manure inside a golden frame. Order here if you dare.)

Yup, that’s a tray made of poop.

Fellow Brits refined Harrington’s design. Alexander Cumming invented the S-trap in 1775, which used a sliding valve called a “stink trap” to seal the bowl’s outlet and prevent sewer stench from entering the home. It is still in use today. Two years later, Samuel Prosser patented the “plunger closet,” which featured a separate flush tank.

After noticing that toilets he installed in London tended to freeze in winter, Joseph Bramah replaced the sliding valve with a hinged flap and also developed a float valve system for the flush tank. Many sources state that a coworker named Mr. Allen devised the apparatus. But Bramah received the patent in 1778 and, as a result, we can’t even find Allen’s first name in historical records. In 1852, George Jennings patented his own improvements and later constructed London’s first public toilets.

At last, we’re back to where we started. When did Thomas Crapper receive patent #4990, prominently featured in his advertisements? He didn’t. Albert Giblin was awarded patent #4990 for his “Improvements to Flushing Cisterns” in 1898. (Many sites mistakenly report the year as 1819. We have located the original patent and drawings.)

Adam Hart-Davis of Exnet used the British Library to painstakingly track down all patents awarded to Thomas Crapper. According to him, “Mr. Crapper took out exactly six, starting in 1881 (#1628) to do with ventilating house drains, and ending in 1893 (#11604) for a mechanism to flush a lavatory by means of a foot lever. None of his patents was #4990. None of his patents was for a valveless water-waste preventer (WWP).”

It’s possible that Giblin, of whom little else can be learned, sold his patent to Mr. Crapper. What we can state with certainty is that Thomas Crapper and Company, claiming to be “The Original Patentees and Manufacturers of Bathroom Appliances,” is still in business today.

The company website tells the story of Crapper’s design of the first automatic flush toilet with a springloaded seat that would fly up, pulling rods which would trigger the flushing action. Unfortunately, with time and use, the rubber buffers attached to the seat’s underside began to break down and become sticky.

“This caused the seat to remain down, attached to the loo pan for a few seconds as the user got to his feet. Seconds later the seat, under stress from the powerful springs, would free itself and sweep violently upwards – striking the unfortunate Victorian on the bare bottom!”

It became known as the “Bottom Slapper” and was not a commercial success. (One could say it was a hit and then it wasn’t.) We trust that the royal family, who contracted Crapper to install plumbing fixtures at Buckingham Palace and Windsor Castle, were never subjected to that indignity.

Manhole covers bearing the company name have become minor tourist destinations. One in particular outside Westminster Abbey, another site supplied by Crapper, has become a popular spot to take brass rubbings. Some of the enthusiasm for this activity may be due to the misconception that the term “crap” as slang for human waste originated with Thomas Crapper. In fact, it predated him by hundreds of years.

He may have been indirectly responsible for the American habit of calling a toilet “the crapper.” Every time U.S. soldiers stationed in Britain during World War I used a bathroom, they saw “CRAPPER” in the porcelain of the toilet and sink. The association between “crap,” “Crapper,” and the act of crapping in a Crapper was so irresistibly hilarious that they brought it home with them, and their descendants continue to use it every day—-in word and deed.

If this holiday, focused as it is on a distasteful bodily function, seems undeserving of your attention, ask yourself this question: If you could only choose one, which could you live without? Your toilet or your iPhone?

Take that, Apple.

January 19 is Tin Can Day

January 19, 2017/0 Comments/in January

Today is Tin Can Day. On this date in 1825, the first U.S. patent for the invention of the tin can was awarded to Ezra Daggett and Thomas Kensett. Like many things, the story of the tin can is not without intrigue. (Tintrigue?) A little history:

France

Paris confectioner Nicolas Appert invented a method of sealing foods in glass jars, then placing them in boiling water, effectively sterilizing them, decades before Louis Pasteur demonstrated that heat killed bacteria.

In 1810, Appert entered a competition sponsored by the French military. He won a cash prize in exchange for making his findings public. The preserved goods were a boon to the armed forces, especially the French navy, which had no fresh food for long stretches while at sea. Appert is considered by many to be the “father of canning,” despite never using cans.

England

There were drawbacks to Appert’s system: glass was heavy, fragile and prone to rupture from internal pressure. Later in 1810, British merchant Peter Durand received a patent from King George III to preserve foods in tinplated cans.

Durand is well-known as the inventor of the tin can but his patent application reveals it was “an invention communicated to him by a certain foreigner residing abroad.” Evidence suggests that Frenchman Philippe de Girard came to London and used Durand as an agent to patent his own creation.

On January 28, 1811, Sir Charles Blagden, a fellow of the Royal Society, wrote of Girard’s frequent visits to test his canned foods on the members. “M Girard came and brought his preserved foods…The broth had been kept since August last, he said. The milk and beef six weeks…His patent is taken out in the name of Durand.”

Why not file in France? Girard had recently designed a flax-spinning loom for which Napoleon promised a reward of one million francs but never paid. But there’s no record of Durand paying him for the rights.

In any case, Durand sold the British patent to Bryan Donkin for one thousand pounds. In 1818, Durand received a U.S. patent for the same design he’d sold in England. Perhaps Durand should be hailed, not as an inventor, but as a recycler. (Girard continued to innovate, without much financial success, until his death in 1844.)

United States

Until America won its independence in 1783, the power to grant patents was that of the British crown. The United States Constitution of 1787 first included provision for the Congress to issue patents:

The Congress shall have Power . . . To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.

The first Patent Act, “An Act to promote the progress of useful arts,” was enacted in 1790 and enabled any two of the secretary of state, the secretary of war, and the attorney general to grant patents lasting 14 years for new inventions and innovations that were “useful and important.”

We have finally arrived at our stated destination. Daggett and Kensett received their patent for the process of “preserving animal substances” on January 19, 1825. More than 4,000 patents had been granted in the United States by that time, one of them Durand’s.

So who should we credit for the tin can? We’re not sure but one person we should all thank is Ezra J. Warner, who patented the first can opener —decades later—on January 5, 1858.
