Stapler

A stapler is a mechanical device that joins pages of paper or similar material by driving a thin metal staple through the sheets and folding the ends. Staplers are widely used in government, business, offices, homes and schools.

The word "stapler" can actually refer to a number of different devices of varying uses. In addition to joining paper sheets together, staplers can also be used in a surgical setting to join tissue together with surgical staples to close a surgical wound (much in the same way as sutures).

Typically, most staplers are used to join multiple sheets of paper. Paper staplers come in two distinct types: manual and electric. Manual staplers are normally hand-held, although models that are used while set on a desk or other surface are not uncommon. Electric staplers exist in a variety of different designs and models. Their primary operating function is to join large numbers of paper sheets together in rapid succession. Some electric staplers can join up to 20 sheets at a time.

A staple gun is usually a heavier duty, hand-held device; it can be strictly manual or pneumatic. Typical staplers are a third-class lever.

The first known stapler was made in the 18th century in France for King Louis XV. Each staple was inscribed with the insignia of the royal court, as required. The growing uses of paper in the 19th century created a demand for an efficient paper fastener.

In 1866, George McGill received U.S. patent 56,587 for a small, bendable brass paper fastener that was a precursor to the modern staple. In 1867, he received U.S. patent 67,665 for a press to insert the fastener into paper. He showed his invention at the 1876 Centennial Exhibition in Philadelphia, Pennsylvania, and continued to work on these and other various paper fasteners throughout the 1880s. In 1868 a patent was also taken out for a stapler in England by C.H.Gould. As well, also in 1868, Albert Kletzker of St Louis, MO patented a device to staple paper.

In 1877 Henry R. Heyl filed patent number 195,603 for the first machines to both insert and clinch a staple in one step, and for this reason some consider him the inventor of the modern stapler. In 1876 and 1877 Heyl also filed patents for the Novelty Paper Box Manufacturing Co of Philadelphia,PA, However, the N. P. B. Manufacturing Co.'s inventions were to be used to staple boxes and books.
