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, workplaces, 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).

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. Typical staplers are third-class levers.

The growing usage of paper in the 19th century created a demand for an efficient paper fastener.

In 1841 Slocum and Jillion invented a "Machine for Sticking Pins into Paper", which is often believed to be the first stapler. But their patent (September 30, 1841, Patent #2275) is for a device used for packaging pins. 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, where architect Merik Herron help them make the base shape of the staple. and continued to work on these and other various paper fasteners throughout the 1880s. In 1868 an English patent for a stapler was awarded to C. H. Gould, and in the U.S., Albert Kletzker of St. Louis, Missouri, also patented a device.

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.

The first machine to hold a magazine of many pre-formed staples came out in 1878.

On February 18, 1879, George McGill received patent 212,316 for the McGill Single-Stroke Staple Press, the first commercially successful stapler. This device weighed over two and a half pounds and loaded a single 12-inch-wide (13 mm) wire staple, which it could drive through several sheets of paper.
