Although functional and practical, Fay's design along with the 50 other designs patented prior to 1899 are not considered reminiscent of the modern paperclip design known today. This clip was originally intended primarily for attaching tickets to fabric, although the patent recognized that it could be used to attach papers together. History Īccording to the Early Office Museum, the first patent for a bent wire paper clip was awarded in the United States to Samuel B. Recent innovations include multi-colored plastic-coated paper clips and spring-fastened binder clips. Some other kinds of paper clips use a two-piece clamping system. The most common material is steel or some other metal, but molded plastic is also used. Paper clips usually have an oblong shape with straight sides, but may also be triangular or circular, or have more elaborate shapes. They are usually used to bind papers together for productivity and portability. When a moderate number of sheets are inserted between the two "tongues" of the clip, the tongues will be forced apart and cause torsion in the bend of the wire to grip the sheets together. Common to paper clips proper is their utilization of torsion and elasticity in the wire, and friction between wire and paper. Most paper clips are variations of the Gem type introduced in the 1890s or earlier, characterized by the almost two full loops made by the wire. A paper clip (or paperclip) is a tool used to hold sheets of paper together, usually made of steel wire bent to a looped shape (though some are covered in plastic).
