The most common type of wire paper clip still in use, the Gem paper clip, was never patented, but it was most likely in production in Britain in the early 1870s by 'The Gem Manufacturing Company', according to the American expert on technological innovations, Professor Henry J.

This clip was advertised at that time for use in fastening together loose leaves of papers, documents, periodicals, newspapers etc. Another notable paper clip design was also patented in the United States by Erlman J. 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 clip 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.
