who invented the bulletproof vest

In , Francesco Maria della Rovere ; During the English Civil War ; One of the first examples of commercially sold bulletproof armour was produced by a tailor. Richard Davis embodied this mentality when he took some Kevlar and fashioned it into a lightweight vest — and his revolutionary design. Stephanie Kwolek, the inventor of Kevlar, the lightweight fibre used in bulletproof vests and body armour, has died at the age of CARDCONNECT IPO Regardless updates using released all check major or. Databases, or all the about on the. Based on Sun.

It is soft and flexible, so that all kinds of garments can be manufactured out of it. The most practical form of garment is a vest, which can be worn at all times as a protection to life. The second kind of fabric is a simple textile goods, being an inch thick and weighing two pounds to the square foot. This fabric resists and wards off all kinds of leaden bullets from military rifles at any distance, dum-dum bullets at a range of yards and steel bullets at a distance of yards.

The third kind of fabric is also of silk, textile, one inch thick, covered on the outside with a steel armor one-sixteenth of an inch in thickness. The silk and steel together weigh four pounds to the square foot, and the armor wards off steel bullets from military rifles at a range of yards.

The same steel bullets can be warded off at a range of , and 50 yards, but the steel armor must be increased to the thickness of one-tenth of an inch and at a range of 50 yards to one-eight of an inch. Tests of this fabric have been made in a number of places, and they have all been successful. One of the most important was at Fort Sheridan. Krag-Jorgensen bullets were fired at a distance of and yards. At the yard range the bullet perforated the steel and imbedded itself in the second thickness of the cloth.

At the range of yards the bullet pierced the entire shield, but the steel mantel of the bullet stopped at the third thickness. A test was made at Chelsea, Mass. Ryder, who is exhibiting the armor cloth in Brooklyn, has arranged for a test in the Montauk Theater building next Tuesday at P.

Historian Paul Collins rediscovered the forgotten inventor and tells Scott Simon the details.

Author Interviews. The outer layer was designed to absorb the bullet's impact, while the inner layer was added to stop further penetration. However, metal body armor was largely ineffective against firearms. In the s, softer body armor was developed by the Japanese, who made the armor from silk. These silk garments proved to be quite effective but also expensive.

After President William McKinley was assassinated in , the US military explored the use of soft body armor as well. The silk-derived garments were shown to be effective against low-velocity bullets, but not the new generation of handgun ammunition.

The US military decided against silk armor because of this, combined with the high price of silk. The flak jacket was invented during World War II. It was made from ballistic nylon and provided protection from ammunition fragments. Flak jackets were bulky and ineffective against most rifle and pistol fire, but they were widely used, as they provided some modicum of protection and allowed soldiers to feel secure.

In the s, new fibers were discovered that made truly bullet resistant vests possible. The fabric was originally intended to replace steel belting in tires, and it was extremely strong. Waterproofing and additional layers of fabric were added to the Kevlar to make the vests more durable and wearable.

To resist shots from military-grade weapons, the silk had to be layered over a thin sheet of steel. Davis, a pizza delivery driver and former marine, was attacked in ; the would-be robbery turned into a shootout. Considering how often police officers faced dangerous situations like this, Davis began working on a body armor design that could be concealed underneath everyday clothing.

He started out using commercial nylon and the dense fibers of car seat belts, but his second patent, in , used Kevlar, a relatively new synthetic that proved much more resistant than nylon. Jennifer Spirko has been writing professionally for more than 20 years, starting at "The Knoxville Journal. Regardless of how old we are, we never stop learning. Classroom is the educational resource for people of all ages.

Obviously, that many layers of silk is even heavier than a metal plate, but further experiments led him to reduce the number to Though still a long way to go, it was clear that the invention of a fabric bulletproof vest was nearing reality. However, Goodfellow was a devoted physician more than anything else, and he abandoned his work with silk to return to his primary profession. This is where we go back to 16th March and that sunny square in Chicago. It was a common right to carry guns at the time but none of the invited audience, not even the mayor, knew exactly what to expect when they saw this duo face each other.

He had hand-sewn the vest on his own but prior to the public test he had never actually tested it. He was lucky to survive. Further experiments proved that only a perfectly sewn vest was fully effective, and the level of precision required was dangerously absent in hand-sewn copies of his version. He was a genius inventor, one of the first people to even think of colour film and the man who invented the telecstrocope — a television prototype that transmitted images and sound, enabling them to be viewed live remotely.

With the invention of appropriate technology years later, his concept became a reality. Szczepanik also invented a few far less mind-blowing but fully operating machines, which made him well-known and well-off. Among these, he created a machine that could print decorative colour tapestry, a grand-grand parent of the colour printer.

After only a few months, the production line was up and running and the vest publicly available to… only the extremely rich. Silk was always very expensive and its investors wanted to capitalise properly on their invention. He never succeeded. The latter, during this promotion period, had gone back to America with his new-found knowledge to again try find investors to start a production line.

It reached its peak popularity after the silk fabric, sewn according to his method, was used to armour the royal coach of King Alfonso XIII of Spain and saved his life during an assassination attempt. He veered away from his original plan and founded the Zeglen Tire Co and American Rubber and Fabric Company, which produced tubeless, impenetrable tires. Unfortunately, we know very little about the prosperity of these companies. So did the silk vest change history?

Both inventors used one of the best-known methods of promoting their products — they offered it to rich, famous and powerful people, such as King Alfonso XIII of Spain. Cortelyou, but was turned down for an unknown reason. Mc Kinley, in September , was killed with a revolver, shot at him from a few metres away.
