hetrickJohn Hetrick’s invention was the first prototype of today’s modern air bags and derived from an accident on a Sunday afternoon drive. In the spring of 1952, Hetrick, his wife and daughter went for a car ride in their 1948 Chrysler Windsor.  The car veered into a ditch on the side of the road to avoid an on-road collision.

Hetrick recalled “As I applied the brakes, both my wife and I threw our hands up to keep our daughter from hitting the dashboard … during the ride home, I couldn’t stop thinking about the accident. I asked myself: ‘Why couldn’t some object come out to stop you from striking the inside of the car?'”

As a retired industrial engineer technician, Hetrick was concerned that there was not a device in the car to cushion the impact of an accident between the vehicle’s interior and the passengers. Hetrick used his experience working with the Navy to create a safety device for vehicles. He received U.S. patent 2,649,311 for “safety cushion assembly for automotive vehicles” on August 18, 1953.

German inventor, Walter Linderer received German patent 896,312 on November 12, 1953.  Linderer’s system involved a compressed air system, which was released by the driver or bumper contact. Later research concluded that compressed air could not expand and fill the bag fast enough for maximum safety.

The space race may have ended, but its legacy will live on in a number of everyday products.

NASA may not have invented Tang, but the legendary agency did contribute to the development of many other products we consumers use every day.  Memory foam, safety grooving and enriched baby formula were all NASA influenced.

Memory Foam –

memoryfoamIn 1966, scientists at NASA developed a open cell polyurethane-silicon plastic to improve the safety of seat cushions on spacecraft and to lessen the impact of landing. The soft cushion material wants to maintain it’s original form and structure when it is compressed. Even after being compressed to 10% of it sizes, the foam will return to its original shape and size which is why it is called memory foam.

Charles Yost, who helped to develop the product, called the substance temper foam. He formed a company to sell the product. The foam was originally used in X-ray tables and football helmets. Today, the substance is used for many applications from the medical industry to consumer products. The foam can be found in couches, mattresses and pillows.  The foam has been added to prosthetic limbs to reduce the friction on joints. Continue reading “NASA Discoveries…Not Just For The Moon”

ivorysoapTo better compete within the soap industry, Proctor & Gamble sought to create a high quality, affordable, duel bath bar and laundry product. In 1878, the first successful formula was created and produced under the name of White Soap.

Rumor has it that the floating soap formula was invented accidentally by one of the Proctor & Gamble’s employees. In 1879, an unknown soap maker left the mixer unattended and running while out for lunch. A batch of White Soap had been over-whipped and unusual amounts of air found its way into the mixture. The soap mixture continued through the rest of the production process and was shipped for consumers. Soon after, company officials began receiving letters requesting more floating soap. The addition of whipped air to the mixture made the soap lighter than water, so it floated.

This is a nice story of a mistake becoming one of Proctor & Gamble’s most successful products, but is it true? According to Proctor & Gamble’s company archivist, Ed Rider, this is a false wives’ tale. Rider had found documentation that a chemist, James N. Gamble, created the floating soap formula. In a document, James Gamble noted “I made floating soap today. I think we’ll make all of our stock that way.” The floating soap had incredible marketing potential and small amounts of air were intentionally whipped into the mixture. This process also produced a smooth textured bar of soap that was easy to lather. Continue reading “Soap Floats – The Invention of Ivory Soap”

machineThe history of popcorn making and corn popping machines have seen much improvement. Advancements have allowed us to efficiently pop our favorite snack just in time for that movie. In the past, many methods had been executed to pop corn as a treat. One simple way was placing kernels over a fire on a hot rock. As the impact of the heat increased on the kernels, they would pop in different directions. People would chase after the pieces in order catch and enjoy the taste of this snack. Sadly, many of the corn kernels were charred. Luckily, there are easier ways to obtain this delightful goody and it began with the world’s first commercial popcorn machine.

Charles Cretors is accredited as the inventor of the first commercial popcorn machine. He first received United States Patent 506,207 on October 10, 1893 for improvements on peanut-roasters or corn-popper. Continue reading “Butter, Salt and Lard – Refining Popcorn”

Question from Greg:

What aircraft and what year where abs brakes installed onto?

Spending a great deal of time looking into this subject, this is what was found; without a certain answer. Modern anti-lock brakes have undergone numerous amounts of alterations from their original form with many individuals taking credit for each milestone abs brakes have reached.

The root development of anti-lock brakes (abs) or anti-skid brakes, as they are more commonly called on aircraft, dates back to 1929. French aircraft pioneer, Gabriel Voisin, originally designed the anti-lock brakes for airplanes. Although it has been stated that the brakes were first intended for aircraft, additional data to backup this claim is very limited. Whether he tested the invention on one of his own famous biplane designs is questionable. We know that after WWI (1918), Voisin stopped developing planes and went into the automobile industry. According to these dates, that means he would have invented abs brakes after the point in which he switch to car production. Perhaps, the invention was a half-baked idea during his flight days (intended for aircrafts) but did not fully developed till his automotive days, in which his anti-lock brake system was installed on cars.

The first noted US produced plane equipped with an Hydro-Aire Mark I anti-skid system was military aircraft Boeing B-47 bomber in 1947. After WWII, landing speeds increased tremendously because of new jet aircraft. Conventional brakes were not as effective and the anti-skid brakes prevented plane wheels from locking on low traction surfaces.

Good Humor PatentIn 1920, a candy maker in Youngstown, Ohio created a recipe for coating ice cream with chocolate. Harry Burt’s smooth chocolate coated ice cream treats were delicious. The first taste tester was his daughter Ruth who loved the flavor but hated the mess. Earlier, Burt had invented a lollipop on a stick known as a Jolly Boy Sucker. Taking the advice of his son, Harry Jr., Burt froze the same stick into his ice cream, creating handles for the treats. Burt named his new ice cream invention the Good Humor Bar. The name came from the belief that a person’s humor or temperament came from their sense of taste.

On January 30, 1922, Burt applied for patents on the process and manufacturing of the frozen treat as well as for the treat itself. The United States Patent Office was reluctant to grant the patents because of the product’s similarities to Eskimo Pies. It took a trip to Washington, D.C. with a five-gallon bucket of Good Humor bar samples before his patent would be approved. Ultimately, Burt received US Patent 1,470,524 for the Process of Making Frozen Confections on October 9, 1923. He did not receive a patent for the confection itself.

The broad basis of Burt’s patent led to a popsicle battle between the major manufacturers. In 1925, Burt sued both of his major competitors, the Citrus Products Company and the Popsicle Corporation for producing similar frozen treats. Eventually, he dropped the suit against the Citrus Products Company because he realized they refused to settle in order to see if his patent would hold up in court. Burt and Popsicle reached an agreement out of court. Popsicle paid a licensing fee to Burt and was permitted to manufacture frozen treats from ice and sherbert. Burt kept the exclusive rights to produce the frozen suckers from ice cream and other dairy products. Continue reading “Bribery, Intrigue and…Ice Cream?”

Statue of Liberty PatentDid you know the subject of America’s most famous design patent wasn’t actually designed by an American?

On February 18, 1879, French sculptor Auguste Bartholdi received US Patent D11,023 for a statue design – one he called, “Liberty Enlightening The World.”

You know her as The Statue of Liberty. She stands tall on her pedestal on Liberty Island, a beacon of hope for Freedom seekers the world over.

But, did you know the greatest symbol of American Opportunity almost didn’t happen due to a lack of funding? It’s true!

Auguste Bartholdi was commissioned in 1876 – the year of the American Centennial – to create the statue as a gift to America; it would be a symbol of friendship between France & the US for everyone to see. France would raise the money to build the sculpture, and America would handle the pedestal.

Simple, right?

Not really.

Even with Bartholdi’s patent – which he got specifically to allow him to create and sell replicas of Lady Liberty as a fundraising effort – France still had trouble finding enough public support. It took numerous auctions, art exhibits, lotteries and theater events were used to raise the needed funds from their end.

Construction of the statue began in 1875 and was not completed until nine years later in 1884. Alexandre Gustave Eiffel, the designer of the Eiffel tower, planned the skeletal framework for the statue. A larger-than-life representation of the Roman Goddess Libertas, Bartholdoi used two different women as models. The face is said to be a likeness of his mother. His wife posed for the arms and torso of Lady Liberty.

Meanwhile, America was having her own bit of funding problems. That is, until Joseph Pulitzer’s shame campaign against the wealthy and middle class alike spurred enough interest to finally fund the pedestal in 1885, just months before the statue – which had been shipped from France July of 1884 – arrived in New York.

So finally, on June 19, 1885, the world’s single, most powerful symbol of Freedom arrived in America in 350 pieces packed into 214 crates. They were reassembled in their place on Bedloe’s Island in New York Harbor. On October 28, 1886, before thousands of spectators, President Cleveland dedicated the Statue of Liberty on the now-named Liberty Island.

Lady Liberty stands 305 feet and 1 inch tall from its base to the tip of the torch and weighs 450,000 pounds. Each year over 3 million people visit the statue that has welcomed immigrants to Ellis Island since 1892.

SupergluepatentYou can add Super Glue to your list of inventions that were discovered by accident. Dr. Harry Coover was not trying to invent a super-sticky substance when he came across Super Glue. In 1945, Dr. Coover was actually working on a way to create a clear plastic to use in precision gunsights for Eastman Kodak.

Cyanoacrylates were not a suitable material for this application. Dr. Coover discovered that the chemicals were extremely sticky. Moisture caused the chemical to polymerize. Every object has a thin layer of moisture so the chemical bonded almost any objects together. Testing on the cyanoacrylates was abandoned for now.

In 1952, Dr. Coover was involved in a very different project. He was working in the Eastman Kodak’s chemical plant overseeing a group of chemist who were looking for heat-resistant polymers for jet airplane cockpits. A rediscovery of the cyanoacrylates showed their full potential. They began testing the monomer and discovered that it did not require heat or pressure to adhere two objects. Again every set of objects that was tested were permanently bonded by the substance.

This time Dr. Coover saw an opportunity to create a new adhesive. He applied for a patent on June 2, 1954. On October 23, 1956, he received United States Patent 2,768,109 for Alcohol-Catalyzed Cyanoacrylate Adhesive Compositions. After refining the chemical, a new product originally known as Eastman 910 hit store shelves in 1958. Continue reading “Wow…That’s Sticky!”

Question from No Name:

When was the bulletproof vest invented? Or should I say Kevlar?

Kevlar was another accidental invention among many others throughout history that has saved thousands of lives. The fabric was originally intended to replace steel belting in the tires of vehicles. A member of DuPont’s Pioneering Research Laboratory, Stephanie Kwolek, first developed the synthetic material in 1965. Kwolek was awarded patent number 3,819,587 in 1974 for “Wholly aromatic carbocyclic polycarbonate fiber having orientation angle of less than about 45º.”

Kwolek had been hard at work developing new polymer solutions when she stumbled onto one that behaved in a way no other solution had before. The particular liquid separated into two distinct layers: one was clear and yellow, and the other was cloudy, shiny, and much thinner than other mixtures. It poured like water, which was also uncharacteristic.

Kwolek and technician Charles Smullen tested the liquid further, spinning it to fibers and ultimately discovering the material’s remarkable capabilities. The substance was lightweight, stronger than steel, chemical, flame, and high cut resistant.

Under DuPont, Kwolek’s material underwent testing as a bullet resistant fiber. DuPont first began marketing Kevlar in 1971 as bulletproof, protective body armor.

Today, Kevlar is used in many other products, including helmets, spacecraft shells, skis, and suspension bridge cables.

FahrenheitIn 1593, when Galileo Galilei invented a basic water thermometer the device was called a thermoscope. His thermoscope and the ones that followed were not standardized in the liquid or the scale for telling the temperature. These simple devices mainly indicated a temperature increase or decrease, but no one was sure by how much. Daniel Gabriel Fahrenheit was a German physicist who changed the way the world viewed temperature.

In 1709, Fahrenheit invented an alcohol thermometer. Then in 1714, he improved on this invention with the introduction of the mercury thermometer. Fahrenheit decided to use mercury after a series of experiments. Mercury expanded uniformly at temperatures ranging from negative 40 to 626 degrees. Fahrenheit also changed the design of thermometers. Previously, thermometers were spherical. A tiny glass bulb held the mercury which rose through a long, cylindrical neck.
