A binder clip, less commonly known as a paper clamp or banker's clip or foldover clip or bobby clip or clasp, is a simple device for binding sheets of paper together. It leaves the paper intact and can be removed quickly and easily, unlike the staple.

Contents

In the United Kingdom it is known generically as a bulldog clip, although this term properly refers to an older device with the same function, which is stronger and has rigid rather than folding handles. To distinguish it from rigid clips, the term foldback clip may also be used. It is also sometimes referred to as a handbag clip because of resemblance to a handbag when its clips are folded up.

Characteristics and methods of use

The handles can be folded down once the clip has been attached, and can also be removed for a semi-permanent binding. Three binder clips.jpg

A binder clip is a strip of spring steel bent into the shape of an isosceles triangle with loops at the apex. Tension along the base of the triangle forces the two sides closed, and the loops prevent the sharp steel edges from cutting into the paper. The loops also serve to hold two pieces of stiff wire, which are used as handles and allow the clip to be opened. The two slots cut in each loop are shaped so that the wire handles can be folded down once the clip has been attached, and the spring force of the wire holds them down on the surface of the paper. This holds the clip relatively flat, for easier stacking of paper. One handle can also be folded down while the other remains up to allow the stack of papers to be hung up. The handles can also be removed altogether by squeezing them sideways and pulling them out, allowing for more permanent binding. As compared to a paper clip, the binder clip is able to bind sheets of paper more securely, and is also resistant to rust.

There are several sizes of binder clips, ranging from a base size of 5 millimetres (0.2 in) to 50 mm (1.97 in). The sheet steel portion is customarily black oxide coated, but a variety of decorative painted color schemes are also available. The sheet steel portion is occasionally made of stainless steel, the more typical spring steel can also be finished in nickel, silver or gold. The handles are normally nickel-plated.

Uses

The binder clip is in common use in the modern office. It can hold a few to many sheets of paper, and is usually used in place of the paper clip for large volumes of paper. Various practical (and sometimes whimsical) alternative uses have been proposed. These include holding pieces of quilt together, creating a "beer pyramid" in a refrigerator with wire shelves, serving as a bookmark, a cheap alternative to a money clip or preventing computer cables from slipping behind desks. [1] Smaller sized clips have been commonly used as "quick fix" fitting and sizing solutions in the fashion industry.

In 1966, test pilot Joseph F. Cotton used the shiny metal portion of such a clip to short-circuit an electrical circuit panel to force the landing gear of the XB-70 bomber on a flight.[ citation needed ]

The object is such a common sight in offices that, in late 2020, when restrictions due to the COVID-19 pandemic were lowered and people started returning to their offices, some missed and enjoyed the feeling of using a binder clip, after months without doing so. [2] At around the same time, healthcare workers in at least one medical center used extra large binder clips as a cheap way to secure a plastic curtain between workers and patients infected with the airborne virus. [3]

History

In 1909, the method of binding sheets of paper together was to punch holes in them and tie them together with string or sew them, making it tedious to remove a single sheet of paper.

The binder clip was invented, and patented [4] in 1910 by Washington, D.C. area resident Louis E. Baltzley, grandson of Elias Howe, [5] to help his father, born in 1848, [6] [7] twin to Edward Baltzley and son of Susan (née Howe) and David C. Baltzley, Edwin Baltzley, developers of Glen Echo Park and Glen Echo, Maryland, [8] a writer, [9] and inventor, [10] with thirteen patents, [5] hold his manuscripts together more easily. While similar-purposed designs have since been patented five times, [5] the most produced version remains the U.S. patent 1,139,627 .

Louis E. Baltzley, with more than thirty other patents, [11] initially produced this invention through the L.E.B. Manufacturing Company. [5] These earliest binder clips are stamped "L.E.B." on one side of the sheet steel. Manufacturing rights were later licensed to other companies.

Louis E. Baltzley

Louis E. Baltzley, born circa 1885, [12] by February 1930, [13] had moved [12] to Glen Ridge, New Jersey married, [14] and had two daughters, [15] one marrying in 1940. [16]

<span class="mw-page-title-main">Paper clip</span> Metal device to hold papers together

A paper clip is a tool used to hold sheets of paper together, usually made of steel wire bent to a looped shape. Most paper clips are variations of the Gem type introduced in the 1890s or earlier, characterized by the one and a half loops made by the wire. Common to paper clips proper is their utilization of torsion and elasticity in the wire, and friction between wire and paper. 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. They are usually used to bind papers together for productivity and portability.

The spring forces the jaws together, gripping the papers firmly.

A staple remover is a device that allows for the quick removal of a staple from a material without causing damage. The best-known form of staple remover, designed for light-gauge staples, consists of two opposing, pivot-mounted pairs of thin, steep wedges and a spring that returns the device to the open position after use. Although a simple metal wedge can be used for the same purpose, and although some staplers feature such a wedge at their hinge end, use of the wedge tends to tear fragile papers.

Bookbinding is the process of building a book, usually in codex format, from an ordered stack of paper sheets with one's hands and tools, or in modern publishing, by automated processes.

One can also use loose-leaf rings, binding posts, twin-loop spine coils, plastic spiral coils, and plastic spine combs, but they last for a shorter time. Next, one encloses the bound stack of paper in a cover. Finally, one places an attractive cover onto the boards, and features the publisher's information and artistic decorations.

A bolt snap is a type of snap hook with a manually operated bolt action slide gate of medium security used to clip a light load to a ring, eye, loop or bight to temporarily secure or suspend an object. They are used for a wide variety of applications including dog leads and for clipping scuba equipment to the diving harness. A similar but more secure device used to attach sails to a stay is known as a piston hank. It differs from a snap shackle in that the load is not carried by the gate. The bolt snap must be actively operated by the user to clip or unclip, and is not easily snagged or unintentionally clipped or unclipped by pressing or bumping against the surroundings.
