The zipper, also known as a zip fastener or simply a "zip," is a widely used device for joining two pieces of fabric or other materials. It consists of interlocking metal or plastic teeth that can be opened or closed by sliding a small handle or pull along a track. The zipper revolutionized the way we fasten and secure clothing, bags, and various other products. Here's a detailed account of the origins of the zipper:
Early Concepts: The idea of a fastening device similar to a zipper can be traced back to the early 19th century. In 1851, Elias Howe, the inventor of the sewing machine, received a patent for an "Automatic, Continuous Clothing Closure." Howe's design used a series of hooks and eyes attached to fabric tapes, but his invention didn't gain much popularity.
Whitcomb Judson and the "Clasp Locker": In the late 19th century, Whitcomb L. Judson, an American inventor and mechanical engineer, developed a device called the "Clasp Locker" in 1893. It featured a series of metal hooks and eyes that could be fastened together. Judson envisioned his invention as a practical solution for fastening shoes, but his design was somewhat complex and not entirely successful.
Gideon Sundback and the Modern Zipper: The breakthrough in zipper design came with the work of Gideon Sundback, a Swedish-American engineer. Sundback was hired by the Universal Fastener Company, later known as the B.F. Goodrich Company, in 1906. He focused on improving and refining the design of the Clasp Locker.
Sundback introduced several key innovations:
- Interlocking Teeth: Instead of hooks and eyes, Sundback used metal teeth with a precise interlocking mechanism. These teeth could be opened and closed smoothly by sliding a slider along the track.
- Symmetrical Design: Sundback's zipper had symmetrical rows of teeth on both sides, allowing the slider to engage the teeth from either direction.
- Patent and Commercialization: Sundback's design received a patent in 1917, and the company began producing and selling the "Separable Fastener" under the name "Hookless No. 2" in 1918.
Popularity and Industrialization: The zipper gained popularity in the 1920s and 1930s for its convenience and versatility. It was initially used in boots and tobacco pouches but quickly found its way into a wide range of products, including clothing, bags, tents, and more. The B.F. Goodrich Company was one of the leading manufacturers of zippers during this time.
Evolution and Modern Usage: Over the years, the zipper design has undergone various improvements. Plastic zippers were introduced in the 1950s, offering a lighter and more affordable alternative to metal zippers. Continuous zippers, which can be cut to custom lengths, were developed for various applications. Today, zippers come in different sizes, materials, and configurations to suit different needs.
In conclusion, the zipper is the result of a series of inventions and innovations by inventors like Elias Howe, Whitcomb Judson, and Gideon Sundback. Sundback's design, with its interlocking teeth and symmetrical construction, laid the foundation for the modern zipper that revolutionized the way we fasten and secure garments and other products.
