The clothespin for hanging up wet laundry only appears in the early 19th century supposedly patented by Jérémie Victor Opdebec.
After World War I, cheap imports from Europe began to flood the market, leading to repeated calls for protective tariffs by Vermont, and the state industry went into decline; in 1920, it cost 58 cents to manufacture one gross of clothespins in Vermont, while imported Swedish clothespins were sold for 48 cents a gross.
The situation worsened after World War II, and the introduction of the electric clothes dryer diminished demand for clothespins, further damaging the industry; the U.S.C.
However, the National Clothespin Company, who had previously moved from its original location across the street, and had been sold to a new owner, managed to stay in business by virtue of a contract with the F. W. Woolworths department store chain.
The profit margin was eaten into further by the increasing volume of cheap Chinese imports; pleas for protective tariffs continued, but to no result.
[8] The wooden clothespins do not transmit heat very effectively, and therefore are safe to touch, even when attached to hot lights for a significant period of time.
People like gaffers, grips, electricians, and production assistants may keep a collection of C47s clipped to clothing or utility belt at all times.
The common, spring-loaded two-piece wood clothespin - marked in some manner with text and/or color-coding for the designated frequency it references, usually with an added piece of thin plywood or plastic on the clothespin to place the text or color-code upon for greater visibility - is the usual basis for these, whether the model club itself provides them already clipped onto a "frequency control board" for the modeler to take for their activity (clipped onto their transmitter's antenna, in a so-called "subtractive" method) or the modeler make them for their own transmitter(s), and places them on a club facility's existing frequency board (the "additive" method).
[13] For many years players in ensembles such as brass bands playing outdoors have used spring pegs to hold their music in place since even the mildest breeze will blow a loose sheet away.
