Metal Zipper
A metal zipper is a zipper with its binding edges consisting of individual pieces of metal that are molded into shape and set at regular intervals on the zipper tape. Metal zippers are mainly made of brass, nickel and aluminium, and given their durability, they are mostly used in jeans, work-wear, heavy luggage and heavy-duty garments that must withstand high strength and tough washing. The metal zipper is the oldest type of workable zipper, having been invented by Gideon Sundback as an improvement of Whitcomb Judson's "Clasp Locker" that majorly consisted of a hook-and-eye shoe fastener. Description A metal zipper consists of two rows of protruding teeth made of metal. The metal teeth may be made of Brass, Aluminium or Nickel, and they are designed to interlock like clasped hands, linking the rows, thus creating a "Continuous Clothing Closure" as Elias Howe would have referred to it. For this to be possible, the metal zipper is usually fitted with a slider, often made of metal. Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Zipper
A zipper, zip, fly, or zip fastener, formerly known as a clasp locker, is a commonly used device for binding together two edges of textile, fabric or other flexible material. Used in clothing (e.g. jackets and jeans), luggage and other Bag, bags, camping gear (e.g. tents and sleeping bags), and many other items, zippers come in a wide range of sizes, shapes, and colors. Whitcomb L. Judson, an American inventor from Chicago, in 1892 patented the original design from which the modern device evolved. Description A zipper consists of a slider mounted on two rows of metal or plastic teeth that are designed to interlock and thereby join the material to which the rows are attached. The slider, usually operated by hand, contains a Y-shaped channel that, by moving along the rows of teeth, meshes or separates them, depending on the direction of the slider's movement. The teeth may be individually discrete or shaped from a continuous coil, and are also referred to as ''elements''. The wor ...

Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nickel
Nickel is a chemical element with symbol Ni and atomic number 28. It is a silvery-white lustrous metal with a slight golden tinge. Nickel is a hard and ductile transition metal. Pure nickel is chemically reactive but large pieces are slow to react with air under standard conditions because a passivation layer of nickel oxide forms on the surface that prevents further corrosion. Even so, pure native nickel is found in Earth's crust only in tiny amounts, usually in ultramafic rocks, and in the interiors of larger nickel–iron meteorites that were not exposed to oxygen when outside Earth's atmosphere. Meteoric nickel is found in combination with iron, a reflection of the origin of those elements as major end products of supernova nucleosynthesis. An iron–nickel mixture is thought to compose Earth's outer and inner cores. Use of nickel (as natural meteoric nickel–iron alloy) has been traced as far back as 3500 BCE. Nickel was first isolated and classified as an e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aluminium
Aluminium (aluminum in American and Canadian English) is a chemical element with the symbol Al and atomic number 13. Aluminium has a density lower than those of other common metals, at approximately one third that of steel. It has a great affinity towards oxygen, and forms a protective layer of oxide on the surface when exposed to air. Aluminium visually resembles silver, both in its color and in its great ability to reflect light. It is soft, non-magnetic and ductile. It has one stable isotope, 27Al; this isotope is very common, making aluminium the twelfth most common element in the Universe. The radioactivity of 26Al is used in radiodating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ is small and highly charged; as such, it is polarizing, and bonds aluminium forms tend towards covalency. The strong affinity tow ...

Whitcomb Judson
Whitcomb L. Judson (March 7, 1843 – December 7, 1909) was an American machine salesman, mechanical engineer and inventor. He received thirty patents over a sixteen-year career, fourteen of which were on pneumatic street railway innovations. Six of his patents had to do with a motor mechanism suspended beneath the rail-car that functioned with compressed air. He founded the Judson Pneumatic Street Railway. Judson is most noted for his invention of the common zipper. It was originally called a clasp-locker. The first application was as a fastener for shoes and high boots. The patent said it could be used wherever it was desirable to connect a pair of adjacent flexible parts that could be detached easily. Possible applications noted were for corsets, gloves, and mail bags. Early life Judson was born March 7, 1843 in Chicago, Illinois. He served in the Union Army and enlisted in 1861 at Oneida, Illinois in the 42nd Illinois Infantry Regiment according to the Illinois Stat ...

Elias Howe
Elias Howe Jr. (; July 9, 1819October 3, 1867) was an American inventor best known for his creation of the modern lockstitch sewing machine. Early life Elias Howe Jr. was born on July 9, 1819, to Dr. Elias Howe Sr. and Polly (Bemis) Howe in Spencer, Massachusetts. Howe spent his childhood and early adult years in Massachusetts, where he apprenticed in a textile factory in Lowell beginning in 1835.

Talon Zipper
The Talon Zipper company was the first zipper manufacturing company. It was founded in 1893 as the Universal Fastener Company, manufacturing hookless fasteners for shoes, but a move to Meadville, Pennsylvania led to it becoming the first manufacturer of zippers. The company flourished through the 1960s when it is estimated that seven out of every 10 zippers were Talon zippers ew York Times 12/7/1981 History The Universal Fastener Company was founded in Chicago in 1893. It was later known as the Automatic Hook and Eye Company, and the Hookless Fastener Company, producing hookless fasteners for boots and shoes. The company later moved from Chicago to Hoboken, New Jersey, and finally to Meadville, Pennsylvania where the modern zipper was invented and where it began to be mass-produced in the 1920s.
