Who invented the Zip?

For that matter who inventted the Safety Pin?


Answers:    Whitcomb L. Judson 1893

In 1851, Elias Howe, the inventor of the sewing machine, developed what he call an automatic continuous clothing closure. It consisted of a series of clasps united by a connecting cord running or sliding upon ribs. Despite the potential of this ingenious breakthrough, the invention was never market.

Another inventor, Whitcomb L. Judson, came up with the thought of a slide fastener, which he patented in 1893. Judson's works was an arrangement of hooks and eyes with a slide clasp that would connect them. After Judson displayed the hot clasp lockers at the 1893 World's Columbian Exposition in Chicago, he obtained financial funding from Lewis Walker, and together they founded the Universal Fastener Company in 1894.

The first zippers were not much of an augmentation over simpler buttons, and innovations came slowly over the next decade. Judson invented a zipper that would constituent completely (like the zippers found on today's jackets), and he discovered it was better to clamp the teeth directly onto a cloth tape that could be sewn into a garment, fairly than have the teeth themselves sewn into the garment.

Zippers were still subject to popping amenable and sticking as late as 1906, when Otto Frederick Gideon Sundback joined Judson's company, consequently called the Automatic Hook and Eye Company. His patent for Plako surrounded by 1913 is considered to be the beginning of the modern zipper. His "Hookless Number One," a device in which jaws clamped down on bead, was quickly replaced by "Hookless Number Two", which be very similar to modern zippers. Nested, cup-shaped teeth formed the best zipper to date, and a machine that could stamp out the metal within one process made marketing the new fastener viable.

The first zippers were introduced for use in World War I as fastener for soldiers' money belts, flying suits, and life-vests. Because of war shortages, Sundback developed a new appliance that used only about 40 percent of the metal required by elder machines.

Zippers for the general public were not produced until the 1920s, when B. F. Goodrich requested some for use within its company galoshes. It was Goodrich's president, Bertram G. Work, who came up next to the word zipper, but he wanted it to refer to the boots themselves, and not the device that fastened them, which he felt be more properly called a slide fastener.

The subsequent change zippers underwent be also precipitated by a war—World War II. Zipper factories in Germany have been destroyed, and metal was scarce. A West German company, Opti-Werk GmbH, begin research into new plastics, and this research resulted in numerous patent. J. R. Ruhrman and his associates were granted a German patent for developing a plastic stepladder chain. Alden W. Hanson, in 1940, devised a method that allowed a plastic coil to be sewn into the zipper's cloth. This be followed by a notched plastic wire, developed independently by A. Gerbach and the firm William Prym-Wencie, that could actually be woven into the cloth.

After a slow start, it be not long before zipper sales soared. In 1917, 24,000 zippers be sold; in 1934, the number had risen to 60 million. Today zippers are glibly produced and sold in the billions, for everything from blue jeans to sleeping bags.

The embryo of the safety pin dates posterior to the Mycenaeans during the 14th century B.C. (Late Mycenaean III era). They are known as fibulae (singular fibula) and were used surrounded by the same manner as modern daylight safety pins. In fact, the extremely first fibulae of the 14th and 13th centuries B.C. looked remarkably like the safety pin. The beginning of the fibulae is detailed in Chr. Blinkenberg's 1926 book Fibules grecques et orientales.

The safety pin be reinvented in July 1849 by American inventor Walter Hunt. The rights to the invention were sold for $400.
